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:
What is a topic?
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.
What topics can Relative Insight identify?
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.
How are topics identified?
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.
Changes to topic names are contained within the particular project you are working on, they do not carry over to other projects in which the topic is surfaced.
