What makes a concept?

In a first step, the significant noun phrases (for example, health care system) are detected in order to identify the most frequently occurring concepts in the data. In the second step, the concepts and their frequencies are collected across all files in the set being processed.

ATLAS.ti actively filters the concepts — only the most relevant concepts are presented in the results. You can review the concepts in their surrounding context in the Quotation Reader, and then decide which concepts you want to be coded automatically.

You can search for concepts in documents, document groups, codes or code groups for concepts.

There are several ways how you can start a concept analysis:

Select the Search & Code tab and from there Concepts.

As soon as you select an entity, ATLAS.ti begins to analyse the data. The results are displayed in form of a word cloud. Optional you can also view the result as list. Just change the view option to List.
