What is a text mining tool

Text mining tools are tools for extracting and analyzing meaning from huge amounts of text data. Using natural language processing technology, desired keywords, topics, human emotions and evaluations can be extracted from text data, and the analysis results can be visualized.

The text mining tool analyzes the text using natural language processing technology and extracts important keywords, topics, emotions, etc. By analyzing the extracted results from the frequency of occurrence and degree of relevance, and visualizing them in graphs and charts, it is possible to identify problems and areas for improvement.

Text mining tools are used for marketing research, social media information gathering, news article analysis and translation.

What you can do with text mining tools

Here are four things you can do with text mining tools.

  • Understanding customer needs
  • Accelerate issue discovery
  • Analysis from a new angle
  • work efficiency

I will explain each.

Understanding customer needs

The first is understanding customer needs.

A text mining tool can classify text data such as customer feedback and inquiries to understand what the most requested or dissatisfied customers are and to which category they belong. In addition, by extracting specific words and phrases from text data, it is also possible to identify what requests, needs, and dissatisfaction customers have. If you know your customers are unhappy, you’ll be able to spot improvements quickly.

By understanding customer needs, it is possible to identify which products and services are popular and whether there is room for improvement.

Accelerate issue discovery

The second is speeding up problem discovery.

You can quickly identify hidden problems and issues by extracting specific keywords and phrases from a large amount of text data. By classifying related keywords and phrases contained in the text as themes, you will be able to find common issues from multiple documents. You can also understand customer emotions and reactions to gauge the severity of issues.

By using text mining technology, companies will be able to take measures against problems seen from text data. Since it is faster than manual analysis by humans, it is possible to respond quickly to complaints and troubles and to prepare for potential risks.

Analysis from a new angle

The third is analysis from a new angle.

Text mining tools are classified and analyzed by segments such as time, period, gender, and age. Analysis definitions can be set according to your company, so you will be able to capture customer needs from multiple angles. Documents and sentences related to the same topic can also be classified together, so it is possible to analyze data from a new angle based on the accumulated analysis data of the company.

Using text mining technology gives companies new analytical perspectives. It can also be expected to lead to improved business performance, such as discovering new business ideas and improving business processes, by noticing information that was overlooked by conventional analysis methods.

work efficiency

The fourth is work efficiency.

Using text mining tools, you can automatically collect, extract, and classify huge amounts of text data. As a result, the conventional effort of manually entering, checking, and summarizing data using Excel and other tools will be eliminated, and work efficiency will be greatly improved. In addition, long sentences can be automatically summarized and displayed visually on dashboards and other places in an easy-to-understand manner, increasing the speed of comprehension when reading.

By using a text mining tool, free-form questionnaire results, which could not be analyzed due to lack of manpower, can be converted into data and used effectively. Work efficiency will be greatly improved as more data can be analyzed in less time.

Types of text mining tools

The main types of text mining tools are:

  • for text extraction
  • For SNS analysis
  • For call center business

I will explain each.

for text extraction

The first is for sentence extraction.

As a text mining tool for document extraction, it has the following features.

  • Extract specific keywords
  • Dealing with non-standard expressions and grammatically complex sentences
  • Supports named entities such as person names, place names, and organization names
  • Classify a large number of documents according to certain rules
  • Extracting important information from large amounts of documents

Text mining tools for extracting documents can efficiently and systematically classify and analyze complex sentences such as newspaper articles and research papers, and are useful in many companies and research institutions.

For SNS analysis

The second is for SNS analysis.

A large amount of text data is posted on SNS every day. Text mining tools can analyze these data and grasp customer preferences, opinions, trends, etc. Key features of text mining tools for social media analysis include:

  • Designed to efficiently collect text data from multiple SNS sites
  • Supports non-standard expressions such as colloquialisms, abbreviations, and slang
  • Automatically extract and analyze hashtags
  • Understanding awareness of specific companies and brands

Text mining tools for SNS analysis are mainly used in marketing, public relations, customer support, etc.

For call center business

The third is for call center operations.

Tools specialized for call center operations can analyze large amounts of voice data and text data held by call centers to analyze customer problems, requests, and complaints. By using text mining technology on data that converts customer remarks into text, you will be able to extract what the customer wants and what kind of problems are hidden, and decide what to do. .

In addition, call centers often communicate by voice, so there are tools that can also mine VOCs based on conversations and customer interactions. Using speech recognition technology, recorded voice data is converted into text data and analyzed. This will allow other employees to effectively understand the content of interactions between call center operators and customers, and will be able to take appropriate measures to address any issues that arise.

Comparison points of text mining tools

When comparing text mining tools, it is important to be aware of the following three points.

Range of analysis

I will explain each.


The first is operability.

It is necessary to check whether the person in charge who handles the text mining tool can easily perform analysis even if they do not have specialized knowledge, and whether it is easy to utilize the output results. For example, ease of use of the GUI, easy-to-understand operation procedures, and intuitive operation. If the tool is easy to operate even for beginners, even if the person in charge of operation changes during operation, it will be easy to take over and stable results will be obtained.


The second is customizability.

After implementing a text mining tool, you may need to customize it according to your company’s specific needs and challenges. For example, if you want to analyze text that contains technical terms or keywords in a specific field, you will need to register the specialized language. Therefore, check whether it is possible to register company-specific terms and product names in the dictionary, whether it is possible to add company-specific analysis items and indicators, and whether the format and format of the data to be analyzed can be set by the tool. let’s go.

If you choose a highly customizable text mining tool, it will be easier for your company to use, and the decision-making speed of management and others may increase.

Scope of analysis

The third is the scope of analysis.

The scope of analysis refers to the type, amount, language, etc. of text data that the tool can handle. For example, one text mining tool may not be compatible with the data formats your company works with. Therefore, check whether the tool can be analyzed according to the scene you want to use, such as document extraction, SNS, call center, questionnaire, and chat.

Also, some tools are better suited for small-scale data analysis, while others are better suited for large amounts of textual data. If you choose a tool that is not suitable for your processing volume, processing may take a long time, so be careful.

The scope of analysis is an important point when selecting a text mining tool. Choose a tool that matches the data your company handles.
