Let's dive right in.

What is Text Analysis?

Text Analysis is the process to extract insights out of unstructured text data. Learn the basics.

What is Text Analysis?

Text Analysis is the process of extracting insights out of unstructured text data. In simple terms, it's a way to get information out of text.

This is done by parsing the text and extracting machine-readable information such as:

  • Word frequency (lists of words and their frequencies)
  • Underlying Sentiment (positive, neutral, negative)
  • Entities (people, organization, events)
  • Keywords
  • Topic detection and categorization

Companies use this AI technique to digest online data and documents at scale, and turn them into actionable insights.

This is traditionally hard to realize because companies have to allocate resources to do this manually as well as there are a lots of hidden trends and insights hard to discover.

Unstructured text can be: customer feedback, email, survey response, support tickets, call center notes, product reviews, social media posts, etc.

Text Analysis can help business:

  • discover what topics people are talking about and the underlying sentiment whether positive or negative
  • understand customers' needs and preferences to build and improve products
  • free up team members from manual processes
  • make it easier to analyze a huge volume of text
  • reduce the error due to manual processing

What are text analysis, text mining, and NLP in a few words?

Let's talk about common terms used such as Text Analysis, Text Mining and NLP

What are text analysis, text mining, and natural language processing (NLP) in a few words

When processing text data, it's very common to see these terms often used interchangeably causing a great confusion.

Text Analysis

Text Analysis is the process to find meaning, patterns and insights, in text data for businesses, to see what customers think of a product or what trends are happening in a certain industry.

It's a way to measure sentiment, or the feeling of a customer towards something.

This can be done with a machine or by hand and the output is a set of graphs, reports, and other visual information.

Text mining

Text mining is a process of analyzing text to find information.
This information can be anything from the sentiment of a customer towards a product, to the topic of a document.

Text mining uses different techniques like machine learning and natural language processing to understand human language.
This is important for companies because it can help them understand customer sentiment and make better products.

Natural Language Processing (NLP)

NLP is the process to help machines read, understand and analyze text that is written in a natural way,that is, the same way that humans do.
NLP is able to understand complicated concepts and ambiguities in text by using algorithms and machine learning.

Why Text Analysis is important?

In this chapter, we're going to understand the benefits of text analysis.

Why Text Analysis is important?

Businesses can only improve things that they know people want or don’t like.

Most businesses use quantitative survey data in order to find areas where they can improve customer experience.
Quantitative surveys are based on predetermined answers. However, they are limited because businesses can only improve things that they already know.

Qualitative data, on the other hand, is not restricted by predetermined answers.
This means businesses can get feedback on what people really think and feel about their product or service.

For this reason, qualitative data is becoming increasingly important in order to get an accurate understanding of customer sentiment.

Text analysis is a great way to get qualitative data.
Text analysis is the process of extracting insights from unstructured data.
This can be done manually or through software.
This includes data that is in the form of text, such as customer feedback, reviews, and social media posts.

For example, a company may run a customer satisfaction survey after a support call, like 'How satisfied were you with the service you received?' and provide a list of pre-defined options.
The problem is that these options are limited and don't let us know why the customer is satisfied or not.
So, it's better to ask open-ended questions to dig deeper into the real customer experience.

So, if you’re looking to improve customer experience, then you should consider using text analysis.

Text analysis is a way of looking at customer responses in order to understand what they are saying.
This technique enables organizations to understand the topics customers mention when they are dissatisfied, but also helps in identifying extremely negative topics versus not so negative ones.

This technique is especially helpful for pinpointing areas where the customer experience can be improved.
Additionally, text analysis can help to identify correlations between different factors (like staff knowledge and customer satisfaction) that can be used to improve the experience.

Overall, text analysis is a great way to understand customer feedback and improve customer experience.

When the machine does text analysis, then we have additional benefits.

Scalability

This technique unlocks the value of processing text on scale.
This allows businesses to focus their resources on more important tasks.
The software can handle large amounts of text data no matter how varied it is.

Text analysis tools are essential for companies that want to keep up with the ever-growing demand for data. The tools can quickly and easily organize and understand text data regardless of its variety.
This makes them a versatile and essential tool for any business.

Text Analysis in real-time

Text Analysis is a great way to detect urgent matters quickly and in real time.
By training text analysis models to look for expressions and sentiments that imply negativity or urgency, businesses can automatically flag tweets, reviews, videos, and the like, and take action sooner rather than later.

Text analysis is growing more and more important as we rely more on digital communication. The ability to quickly and accurately detect sentiment and emotion in text can be the difference between a successful business and one that falls behind.

For example, it be used to monitor social media for mentions of the business. By tracking what people are saying about the business online, the business can get a sense of the public’s perception and respond quickly if necessary. Just remember that more than 500 million of tweets are sent each day.

Text analysis can also be used to monitor for specific keywords or phrases. This can be helpful in identifying potential crises before they happen. For example, if the company is tracking mentions of the word "bankruptcy" it can be alerted to potential financial trouble before it becomes a major issue.

Text analysis can also be used to monitor customer service channels. This can help businesses detect and address negative sentiment before it spreads.

Deliver consistent criteria

Humans make mistakes while processing a large amount of data.
So, when processing text, it's best to delegate this task to computers, because they work faster and are more consistent with the results, meaning that the output will be more accurate and less error-prone.

Text analysis is essential for businesses in order to make consistent decisions and to avoid costly mistakes.
For example, if a company wants to analyze the sentiment of customer feedback, the computer can be programmed to identify words and phrases that indicate a positive or negative sentiment.

What are the main algorithms, methods and techniques in text analysis?

Let's take a look at the algorithms, methods and techniques used for Text Analysis.

What are the main algorithms, methods and techniques in text analysis?

Let’s dive into the main text analysis techniques and see its purpose.

Text classification

Text classification is the process of labeling unstructured text with categories or tags. This is done by using predefined tags or categories.

This is helpful for organizing and understanding text. Text classification is used in a variety of industries, such as marketing, healthcare, and finance.

There are many different text classification algorithms.The most common are:

  • Naïve Bayes: A Naïve Bayes classifier is a probabilistic classifier based on Bayes Theorem, with the assumption of independence between features. It is used in text classification, i.e., sentiment analysis, document categorization, spam filtering, and news classification. This machine learning/AI technique performs well if the input data are categorized into predefined groups. Naïve Bayes is a conditional probability model. Given a problem instance to be classified, represented by a vector x = (xi . . . xn) representing some n features (independent variables), it assigns to the current instance probabilities for every of K potential outcomes.
  • Support Vector Machines: Support Vector Machine (SVM) is one of the most extensively used supervised machine learning algorithms in the field of text classification. Support Vector Machine constructs a hyperplane or set of hyperplanes in a very high or infinite-dimensional area. It computes the linear separation surface with a maximum margin for a given training set. Only a subset of the input vectors will influence the choice of the margin; such vectors are called support vectors. When a linear separation surface does not exist, for example, in the presence of noisy data, SVMs algorithms with a slack variable are appropriate. This classifier attempts to partition the data space with the use of linear or non-linear delineations between the different classes.
  • Deep Learning: Deep learning methods are proving very good at text classification. Recurrent Neural Networks (RNN) are commonly used in text classification. Deep learning algorithms like Word2Vec, GloVe and Convolutional Neural Networks (CNN) are also employed to get high-ranking vector representations of words and improve the accuracy of classifiers based on traditional machine learning/AI algorithms. CNNs are good at extracting local and position-invariant features, while RNNs are better when classification is determined by a long range semantic dependency. CNNs are better at detecting features in text, while RNNs are better at understanding the meaning of text. For example, CNNs may be used to find specific words or phrases that indicate whether a text is positive or negative, while RNNs could be used to generate a sentence based on a series of text. Let's compare CNN and RNN in terms of speed. CNN are very fast and can be used to predict the sentiment of a restaurant review without using the information stored in the sequential nature of the data.
  • Transformers architecture: A transformer is a deep learning model that helps computers understand language and images. It is used in fields like Natural Language Processing (NLP) and Computer Vision (CV). Transformers are a type of neural network that are better at doing natural language processing than other kinds of neural networks such as RNN models suffer from the problem known as vanishing gradient problem and therefore fail to model the longer contextual dependencies. We can also use the HuggingFace transformers for text classification.

Each algorithm has its own strengths and weaknesses. Naïve Bayes is simple and fast, but it is not as accurate as other techniques. Support Vector Machines is very accurate, but it is slow and complex. Neural Networks are accurate and fast, but they are also complex and expensive to train.

Which algorithm you use depends on the specific application and the data set. For example, if you are trying to classify text data that is highly unstructured, you might want to use a neural network. If you are trying to classify data that is more structured, you might want to use a support vector machine.

The most common text classification tasks are sentiment analysis, topic modeling, language detection, and intent detection:

1- Sentiment Analysis

Sentiment analysis is a way of understanding the feelings or emotions of people in relation to businesses or products. Companies use sentiment analysis to read and classify opinions for polarity (positive, negative, neutral). This can help businesses improve their products.

People leave their opinions about businesses and products on the internet.
You can use machine learning techniques to read these opinions and figure out if they are positive, negative, or neutral. Once you have the data, you can act on it. For example, if you find that people are leaving negative comments about your product, you might want to make some changes.

There are a few different ways to do sentiment analysis. The most common way is to use a machine learning algorithm called a classifier. A classifier is a program that takes a set of data and divides it into categories.
There are a lot of different classifiers, but the most popular ones are Naïve Bayes, Support Vector Machines, Random Forest and Transformers models such as Roberta.
Each classifier has its own set of rules, and you have to choose the right one for your data.

For example, companies using Sentiment Analysis can detect complaints, let's see an example for the airlines industry.

2- Topic Modeling

Topic modeling is an unsupervised machine learning technique that automatically analyzes text data to determine clusters of words and phrases based on their commonality. This is done by assigning tags or categories to each individual text's topic or theme.
In this way, the text data can be easily sorted and analyzed.

Topic labelling combined with sentiment analysis allows you to determine what aspects of your product people are talking about.

Topic modelling is a great way to get an overview of what a text is about. It can be used to find the dominant topics in a text, or to identify key topics that are mentioned multiple times. This is useful for understanding what a text is about, and for identifying key areas of a text that you may want to focus on for further analysis.

There are a few different techniques that can be used for topic modeling:

  1. Latent Dirichlet Allocation (LDA): It is a popular technique for topic modeling. It works by assuming that each document is made up of a mixture of topics. These topics are then assigned a probability, and the documents are sorted according to their most probable topics.
  2. Hierarchical Latent Dirichlet Allocation (HLDA): It is similar to LDA, but it takes into account the hierarchical structure of a document. This can be useful for documents that are made up of multiple sections, such as a research paper.
  3. Latent Semantic Analysis (LSA): It is a technique that is used to find the most important words in a text. It does this by analyzing the relationships between words. This can be useful for identifying words that are related to a particular topic.
  4. Probabilistic Latent Semantic Analysis (PLSA): It is a more recent technique that builds on LSA. It uses a probabilistic model to find the relationships between words. This allows it to identify words that are related to more than one topic.
  5. Use deep learning and transformers architecture. BERTopic is a topic modeling technique that leverages transformers and c-TF-IDF to create dense clusters allowing for easily interpretable topics whilst keeping important words in the topic descriptions.

Unlike topic modeling, in topic classification you already know what your topics are. Topic classification is when you know what your topics are before you start. You need to give the computer documents that are already labeled by topic. The computer will learn how to do this by itself. An example of this is when you want to categorize customer support tickets by Shipping Issue and Pricing.

You can use any classifier to support this technique such as Transformers.

Basically, you need to encode the text using a transformer. This will create a sequence of numbers that represent the text. The computer can then learn how to identify the topics.

4- Intent Detection

Intent classification is the automated categorization of text data based on customer goals. It's a way for understanding the reason behind a customer's actions. In other words, intent classification is a way of understanding the reason behind customer feedback. Machine learning can read chatbot conversations or emails and automatically route them to the proper department or employee.
This is useful for understanding the intentions behind customer queries, automating processes, and gaining valuable insights.

When it comes to intent detection, there are three main types of classifiers:

  • Supervised learning algorithms: These algorithms require a training set of data that is labeled with the correct intent.
  • Unsupervised learning algorithms: These algorithms do not require a training set. They are used to find patterns in data.
  • Semi-supervised learning algorithms: These algorithms require a training set of data, but some of the data is not labeled with the correct intent.

Supervised learning algorithms are the most common type of algorithm used for intent detection. There are two types of supervised learning algorithms:

  • Neural networks: Neural networks are a type of machine learning algorithm that are modeled after the brain.
  • Support vector machines: Support vector machines are a type of machine learning algorithm that are used to find the best decision boundary for a classification

Intent detection is important for customer service because it allows you to route customer feedback to the correct department. For example, if you receive a customer complaint, intent detection can help you to determine whether the customer is angry, confused, or requesting a refund.

Sales teams need to be quick to respond to any potential customers in order to close the deal. Prospective clients appreciate fast responses, and some even expect a response within 6 hours. If someone messages you on Facebook asking about product availability, an intent classifier can identify this as an interested client and you can contact them as soon as possible.

Intent detection is also useful for understanding customer sentiment. If you're tracking customer satisfaction, you can use intent detection to determine whether a customer is happy or not. For example, if you're selling a product that has a lot of negative reviews, you can use intent detection to determine the cause of the dissatisfaction.

Intent detection is a valuable tool for understanding customer behavior. By understanding the reason behind customer feedback, businesses can improve their customer service and make necessary changes to their products.

This is saying that if you want to increase your sales, you can use a program that will identify people who are likely to buy and contact them quickly. This will increase your conversion rate, or the percentage of people who actually buy something. There are many programs that can do this. Some are quite expensive, but there are also some free ones. The important thing is to find the right one for your business.

Once you have a program like this, you need to set it up properly. This means creating a list of criteria that the program can use to identify potential customers. You also need to create a list of keywords that the program can use to find potential customers.

Once you have set up the program, you need to test it. This means putting it into action and seeing how well it works. You can then make changes to the program based on the results.

Once you have a working program, you need to track the results. This means measuring how well it is performing and making changes to it if necessary.

You can also use a program like this to find potential customers on social media. This can be a great way to increase your sales.

Text extraction

Text extraction is a process where you take pieces of data from a text. This can be done manually by reading through a text and extracting information, or by using a computer to automatically pull out specific information. You can extract keywords, prices and entities such as locations, people, company and product names.

This is done with a program called a text extractor. A common extractor is Named Entity Recognition (NER).

NER is a great tool for extracting information from texts. It is able to identify specific entities and extract them for further analysis. This can be used for a variety of tasks, such as market research, competitive analysis and more. For example, you could extract all the company names from a text and create a list of all the companies mentioned.

Keyword extraction is the process of identifying keywords in a text and extracting them for further analysis. This can be used for a variety of tasks, such as market research, competitive analysis and more. For example, you could extract all the keywords from a text and create a list of all the keywords mentioned.

Price extraction is the process of extracting prices from a text. This can be used for a variety of tasks, such as market research, competitive analysis and more. For example, you could extract all the prices from a text and create a list of all the prices mentioned.

You can start apply text extraction to do your own keyword extraction for SEO purpose as well.

Word Frequency

Word frequency is a technique that measures how often a word or phrase appears in a text.

It can be used to analyze customer support conversations to see what words or expressions are used most often. For example, if the word 'delivery' appears most often in negative support tickets, this might suggest that customers are unhappy with the delivery process.

Word frequency analysis can also be used to improve the content of your website or blog. By analyzing the words that are most commonly used on your website, you can identify topics that you should write about more often. You can also use word frequency analysis to improve your SEO strategy by identifying the keywords that are most relevant to your business.

There are a few different ways to calculate word frequency. The most common approach is to count the number of times a word appears in a text. You can also calculate the frequency of a word relative to the other words in the text. This approach is known as the 'frequency of occurrence'.

The simplest example can be counting words in text and see what is the word that appears most frequently to get the grasp of the topic of the long text.

Complicated example includes analyzing sentiment(mood) of a given text, or use the data to generate recommendation list of some product or service.

Using plain Unix tools:

#/bin/bash
cat $* | tr -sc A-Za-z '\012' | sort | uniq

Concordance

Concordance is a tool that helps us understand how words are used in different contexts. This can help us understand the meaning of words that might be ambiguous. It can also help us find synonyms and antonyms for words that we are using.

Concordance and NLP are both very useful tools. Concordance can help us make sure that we are using words correctly and that we are getting the nuance of the words correct. NLP can help us find the right words to use in our writing, to make sure that our writing sounds natural.

For example, concordance can help students understand the meaning of words they are learning in their classes. NLP can help students understand the meaning of words they are learning in their classes, as well as help them with their pronunciation.

Concordance and NLP can also be used in the business world. Concordance can help us make sure our language is accurate and precise. NLP can help us sound more natural when we are speaking, and make sure our language is easy to understand.

Collocation

Collocation is the grouping of words together that often appear together. Collocation can be helpful to identify hidden semantic structures and improve the granularity of the insights by counting bigrams.

In natural language processing (NLP), collocation is often used to determine the meaning of a word or phrase. For example, the word "bank" can have several different meanings, such as a financial institution, the side of a river, or a slope. However, when the word "bank" is used in the phrase "bank robbery," the meaning is clear because of the collocation of the words.

There are many different ways to measure collocation. One common way is to measure the frequency of two words appearing together. This can be done in a text corpus, which is a collection of texts that can be used for analysis. A bigram is a pair of words that occur together, and a trigram is a trio of words that occur together.

Collocation is often used to determine the meaning of a word or phrase.

Bigrams and trigrams can be used to determine the meaning of a word or phrase. For example, the phrase "red flag" has a different meaning than the phrase "red car." This is because the word "flag" has a different meaning than the word "car." However, when the word "flag" is used in the phrase "red flag," the meaning is clear because of the collocation of the words.

Collocation can also be used to improve the accuracy of a machine learning algorithm. For example, if a machine learning algorithm is trying to determine the meaning of a word, it can be improved by using collocation. This is because collocation can help to determine the meaning of a word based on its context.

Clustering

Text clustering is a way of grouping together vast quantities of unstructured data. This is done by algorithms that are not as accurate as classification algorithms, but they are faster to implement. This is done without the use of training data, which is known as unsupervised machine learning.

Text clustering is used to group together similar words that appear close to each other in a text document. This is done by using a distance metric, which is a measure of how different two items are.

The most common distance metric is the Euclidean distance, which is the distance between two points in a three-dimensional space. It is easy to calculate and it produces good results. The Manhattan distance is a good choice when the data is not linearly separable. The Chebyshev distance is a good choice when the data is not symmetrical.

The most common way to group similar words together is by using a k-means clustering algorithm. This algorithm starts by choosing a number, k, which is the number of clusters that will be created. Then, the algorithm assigns each word to the cluster with the closest centroid. A centroid is the center of a cluster. The algorithm then recalculates the centroids for each cluster, based on the words that have been assigned to it. This process is repeated until the clusters no longer change.

How to use Text Analysis?

Text Analysis is used in different ways within experience management. Let's see some use cases and applications.

How to use Text Analysis?

Text is a big part of businesses and there are ways to use text analysis to make processes more efficient. Automated text analysis can help with things like understanding customer insights and reducing turnover impacts. You don't need any data science or engineering experience to do it!

We can unpack applications and example in Text Analysis into 5 categories: Customer Experience, Employee Experience, Product Experience, Brand Experience and Customer Support.

Customer Experience

Sales Automation

Sales automation is a technology that helps to categorize inbound messages (emails, chats, SMS) into different categories, such as "interested", "not interested", "support", "sales" and "qualified" etc. This allows sales teams to prioritize leads in a more effective way, which increases loyalty and helps predict cross-sell potential. It also helps discover what promoters and detractors are talking about your brand using sentiment analysis.

Prevent Customer Churn

NLP helps predict and prevent customer churn. It can help predict and prevent customer churn by understanding how customers feel about a company, its products, and its services. NLP can also help identify indicators of customer churn.

You will be able to:

  • Understand the experience of your customers by analyzing open-ended NPS feedback
  • Discover and monitor customer sentiment by topic over time. Identify and fix indicators of customer churn
  • Understand exactly what bugs or features customers mention most.

According to this report, 89 percent of customers change brands because of poor customer service.

Employee Experience

Sentiment analysis is a way to measure how people feel about something. It can be used to find out if employee are happy or not with the organization. It can also be used to find out if people are feeling sad or anxious.

Key benefits are:

  • discover low sentiment around managers
  • discover depression and anxiety
  • discover insight into work-life balance and make informed decisions on how to improve workplace satisfaction

Product Experience

Product Reviews

Sentiment analysis is a way to automatically understand the opinion or feeling of a text. You can use it to figure out how people feel about a product by looking at reviews.

Key benefit is the ability to rurn reviews into business improvements.
You will be able to:

  • generate more leads by knowing how to improve review ratings and product claims
  • know and fix the most common product problems in public reviews
  • build in the requested features that customers are actively talking about.
  • be proactive and not reactive to changing customer sentiment and demands. Counter customer churn by anticipating problems and redirecting to key product features.

Business reviews can be an incredibly useful tool for attracting new customers, according to this report.

Discover New Markets

Using text analysis, you can discover new markets and trends for products.

You can identify patterns, topics, interests and trends that matter most to target markets.

It's good way to execute demand generation and sales strategies based on accurate analyses of customer opinions and feelings.

Brand Experience

Similar to product reviews, marketing agencies send out surveys to gauge public opinion about a product or project. They need a way to manage the large amount of data they are getting and to understand what people like and don't like about the product or project.

They will use this information to improve the brand. Basically, they try to analyze drivers of satisfaction for their campaigns.

Customer Support

Ticket tagging is an integral part of support team. They receive a high volume of support tickets every day, many of which are time sensitive. To make this faster, we need to eliminate the need for human intervention in the tagging and routing process.

Text analysis using machines helps customer support team to route tickets to the right team in real time by tagging the tickets with the correct topic.

This allows them to reduce their first response time and improve their ticker routing process.

What are some Text Analysis tools?

Here is a list of Text Analysis tools that you can use to process text.

What are some Text Analysis tools?

Python

Python is the most popular language for scientific computing. It is fast and dynamic, and has a lot of libraries for doing text analysis.

Most libraries include:

  • Tokenization: Splitting text into individual words
  • Stemming: Reducing words to their root form
  • Lemmatization: Converting words to their dictionary form
  • POS tagging: Assigning a part of speech to each word
  • Chunking: Breaking text into smaller chunks

NLTK

NLTK is a library that helps people analyze text.

There are many different tools that NLTK offers for text analysis. The most basic tool is the corpus, which is a collection of text. You can use the corpus to analyze the frequency of words, or to find examples of a particular word.

Another tool that NLTK offers is the tagger. The tagger assigns tags to a piece of text, which can be used to analyze the text further.

The parser is another tool that NLTK offers. The parser breaks a piece of text down into its constituent parts, which can be used to analyze the text further.

Finally, the lemmatizer is a tool that NLTK offers. The lemmatizer assigns the lemma (base form) of a word to a piece of text. This can be used to analyze the text further.

All of these tools are available in the NLTK library. They can be used to analyze text in a variety of ways.

SpaCy

SpaCy is a library used for text analysis that is stronger than NLTK.

One of the advantages of SpaCy is that it has a wide coverage of languages. This means that you can use it to perform text analysis on a wide variety of languages.

Another advantage of SpaCy is that it has a strong deep learning integration. This means that you can use it to perform more sophisticated text analysis tasks, such as sentiment analysis or machine translation.

Finally, SpaCy also comes with a number of convolutional neural network models. These models are designed to work with text data, and can be used to perform tasks such as language modeling or part-of-speech tagging.

Another advantage of SpaCy is that its algorithms are more accurate than those of NLTK. This means that SpaCy is better at understanding text and extracting information from it.

Finally, SpaCy is also faster than NLTK. This means that it can handle more data and produce results more quickly.

Scikit-learn

Overall, Scikit-learn is a great tool for text analysis. It is fast, flexible, and easy to use.

Transformers

Transformers are a type of neural network architecture that doesn't use recurrent connections, which are thought to be necessary for tasks like understanding language.

This new kind of neural network that is designed to do better than traditional networks at tasks like understanding natural language because it relies on a special kind of attention mechanism to do its job.

The transformer’s attention mechanism is inspired by the way humans pay attention to certain parts of a scene or conversation.

The transformer was first proposed in a paper by Google researchers in 2017. Since then, the transformer has become a popular model for natural language processing tasks, and has been applied to areas like machine translation and question answering.

You can find a lots of pre-trained models based on the transformer architecture in HuggingFace website. These models can help you with NLP tasks such as filling mask, question answering, text classification, summarization, etc.
