Text Analytics VS Keyword Search

Text Analytics

The process of analysing unstructured text, extracting essential information, and translating it into structured data that may be used in a variety of ways is known as text analytics. 

Text analytics combines machine learning, statistical, and linguistic tools to deduce insights and patterns from vast amounts of unstructured text or text that does not have a specified format. 

Text analytics is being employed in a wide range of big data applications, from social media analysis to warranty and fraud analysis. Furthermore, businesses are increasingly turning to a combined perspective of structured and unstructured data to acquire a complete picture.

It lets corporations, governments, researchers, and the media make critical decisions using the vast amounts of data available. Sentiment analysis, topic modelling, named entity identification, phrase frequency, and event extraction are some of the approaches used in text analytics.

Keyword Search

When we utilise keyword (word) search, we type a few terms into a search engine, and the machine returns one or more documents that include those words. Each hit corresponds to a single document, which you must study to determine whether it is relevant. As a result, if you have 1000 hits, you must read 1000 documents.
 

It is basically the process of finding the documents and texts that contain a specified word or group of words.

Differences 

Search is the process of fetching a document based on what the end-user already knows they seek. The goal of text analytics is to find information. While text analytics is not the same as search, it can help to supplement search strategies. Text analytics paired with search, for example, can be used to improve document categorisation or classification and to generate abstracts or summaries. They both work on unstructured data.
 

The end-user can utilise a keyword search to locate papers that contain the names of a company’s competitors. A group of documents would be returned from the search. The end-user could only find relevant answers to their questions by reading the documents. It is retrieval-based.

Text analytics returns fragments of information that require human intervention to assemble and interpret. It gathers insight from texts.

Frequently Asked Questions
