When analyzing a comparison, Relative Insight identifies differences, frequencies and similarities across topics, phrases, words, emotions and grammar.

This article covers the important things to know about topical analysis:

A topic is a classification under which words are grouped, based on a shared theme or mental concept.

For example, the topic 'parts of buildings' contains words such as room, bedroom, ceiling and hundreds of similar words and phrases.

Relative Insight uses a topic hierarchy that consists of 21 top-level categories and over 420 sub-categories that cover a broad range of tangible and commercially relevant domains.

The 21 top-level categories are:

We also have a complete list of topics available as a downloadable resource, which details all 420 sub-categories.

Words are imprecise and can take on different meanings in different contexts. Consider the word 'spring' that can be used as a verb, a season, a mechanical component or a body of water. This underscores the importance of analyzing text in a way that considers not just a specific linguistic feature but also the words and phrases that surround it.

Relative Insight does this through a combination of predefined classifications and machine learning that enables the platform to make informed judgements about the topic(s) present in a text.

When exploring the results of a comparison, you can choose to rename topics. Any changes will be reflected on any insight cards where the particular topic(s) are present.
