Content to display articles: top concepts
The top concepts in articles represent a list of entities (people, organizations, and locations) and non-entities that best describe what articles are about.
Concepts used in the search are hidden by default. If you would like them to appear within the top concepts visualization, you should uncheck the window “Hide concepts used in search”.
The computation of top concepts can be done in 3 ways - by importance, frequency, or uniqueness.
Importance
The importance criterion means that the concepts which are more important in the results and appear more frequently in the results will get a higher score. The most important concept will get a score of 100, while the remaining ones get proportionally lower scores.
Frequency
In this case, the concepts are scored based on how frequently they appear in the results. The value that is shown for each concept is the percentage of the results in which the concept appears.
Uniqueness
The uniqueness criterion identifies the concepts that are more likely mentioned in the resulting articles and much less likely mentioned in all other articles. This criterion is useful for identifying unique concepts that are otherwise not frequently present in the articles but are more specific to the topic of your search.
