Here is a quick video showing how to make a concept. 

The Concept Modeler is a tool for additional analytics in Gavagai Explorer

You can define different concepts in Explorer and then analyze your data with respect to them. Same as models, concepts are independent from projects and one concept can be used in different projects. A concept is defined by its including terms. In contrast with topics, the including terms in a concept do not need to be synonyms or semantically similar terms, but they are elements that jointly define that concept. Let’s give an example.

In Hotel Reviews you might define a topic called breakfast, including the terms “breakfast” and “the breakfast”. Each of these terms that appear in a text we will know that the topic breakfast is included in the text. Now consider the two following sentences retrieving from texts:

  • They had excellent organic coffee available in the lobby.

  • I enjoyed starting the mornings with cinnamon latte and croissant.

None of the words “coffee”, “latte”, “croissant” or “mornings” can define the topic breakfast independently; as the case in the first sentence, but a combination of these words can tell us that the text might be related to the concept breakfast; as the second sentence.  

Therefore, the concept breakfast can be defined by set of words like {tea, coffee, latte, bread, cheese, jam, morning,…}. 

You can start defining the concept by a few most necessary words. Then Explorer will show you more suggestions to be added to your concept.

It is also possible to create a concept from a topic in Explorer. When you open a project, in the left panel of the GUI and for a topic of your choice, you can click on Edit terms button which is located next to the blue topic box.

Then, in the top right corner of the grey area, there is a button for creating a concept from your topic. When you click on this button, a confirmation pop up will appear and after you click ok, Explorer creates a concept from your topic. The concept has the same name as your topic and same terms as your topic terms. When your concept has been created, you can choose to either stay in your project page or go to that concept page to edit it.
