    Text clustering is a procedure that involves grouping or segmenting texts into clusters based on their similarities or relevance. This helps identify patterns, relationships, or themes within a large set of texts, enabling more efficient analysis and understanding of the data.

Applications of Text Mining

 Here are a few of the multiple uses that text mining has across numerous sectors. 

  • Sentiment Analysis

Sentiment analysis, or opinion mining, is a widely used text mining application that tracks customer sentiment towards a company. By mining text from online reviews, social networks, emails, call centre interactions, and other sources, sentiment analysis identifies common threads that indicate positive or negative feelings from customers. This information can be utilised to address product issues, improve customer service, and plan effective marketing campaigns. 

  • Resume Screening

Text mining is employed in screening job candidates based on the wording and content of their resumes. Organisations can identify relevant skills, qualifications, and experiences by analysing the text, making the candidate selection process more efficient and effective.

  • Spam Detection

By analysing the content and characteristics of incoming emails, text mining algorithms can identify patterns and indicators of spam, allowing organisations to filter out unwanted messages.

  • Content Classification

Text mining facilitates the classification of website content into different categories. By analysing the text on web pages, text mining algorithms can automatically categorise and organise the content, making it easier to search for specific information or navigate the website.

  • Fraud Detection

The identification of possibly fraudulent insurance claims is made easier by text mining. It analyses the linguistic data in claim forms, emails, and other pertinent documents to find suspicious trends or discrepancies that might be signs of fraud.

  • Medical Diagnosis

In order to help in diagnosis, text mining algorithms are used to analyse reports of medical symptoms. It can extract useful information and help healthcare professionals make accurate diagnoses and treatment decisions by mining medical texts, research articles, and patient records.

  • Electronic Discovery

Text mining is used in examining corporate documents as part of electronic discovery processes in legal cases. By analysing large documents, it can identify relevant information, relationships, and patterns, helping legal teams gather evidence and build cases.

  • Chatbots and Virtual Assistants

Chatbots and virtual assistants use text mining algorithms to comprehend user questions and provide relevant answers. Natural language understanding (NLU) technology, a subtype of natural language processing (NLP), enables chatbots to accurately and pertinently respond to user enquiries by comprehending spoken and written human language.

  • Natural Language Generation

Natural language generation (NLG) is a related technology that utilises text mining to extract information from various data sources, such as documents and images, and then generates human-like text. NLG algorithms can be used to write descriptions for real estate listings, explain key performance indicators in business intelligence systems, and other automated content generation tasks.
