Using the Entity Browser view
Prerequisite: Performing the Entity Extraction
The Entity Browser view can be used to browse the entity information extracted from the set of documents. By default the Entity Browser view is opened behind the Workspace Navigator view. To bring it to front, click its title bar.
Elements of the Entity Browser View
The view consists of the following elements:
Context Menu:
The context menu can be accessed by clicking the small triangle next to the title tab. The context menu contains the following actions:
-
Refresh - forces the system to reload the data in the Entity Browser
-
Filter Entity Types... - Allows to filter out certain entity types
-
Sort Entity By
-
Alphabetic - orders entities in the Results Tree in alphabetic order
-
Frequency - orders entities in the Results Tree by number of occurrences (frequency)
-
Related Docs - orders entities in the Results Tree by number of related documents (documents which contain the entity)
-
Project Selector:
The project selector is used to select one of the existing case projects in the workspace.
Entity Search field:
The search field is used to search for specific entities. It supports * as a wildcard for any characters. For example, the search term "Barac*" will find any entity starting with "Barac". Enter a search term and click Search. The results will be shown in the result tree.
Back Navigation:
This drop-down element shows a list of previously defined search operations. Select one to go back to previous search results.
Entity Result Tree:
This is a tree-like viewer which shows the found entities ordered by type.
The viewer has two additional columns:
-
Freq - Frequency of Occurrence, the number of occurrences of an entity across all documents
-
Docs - Related Documents, the number of documents which contain the entity
By default the columns show the frequency and related documents of an entity across all documents in the case project. If a search for a specific entity or entities related to a specific entity is active (see the Back Navigation drop down) the data in relation to the current search is shown.
Entity Context Menu:
Right-click on an entity to show the Entity Context Menu. The context menu contains the following actions:
-
Add to Graph - adds the selected entity to the Graph view
-
Show related entities - shows the related entities of the entity in the Browser view. This action is added to the Back Navigation. This action switches the data in the frequency and docs column in relation to the selected entity.
Using the Entity Browser view
The view shows all found entities in a result tree ordered by entity type.
Searching for a specifc Entity
In order to search for a specifc entity, do the following:
-
Enter the name of the entity or the start of the name in the Entity Search Field
-
Click Search or hit the enter key
The search field supports the use of wild card symbols to search for parts of names, for example “Franz*” searches for all entities which start with “Franz”. The wildcard patterns support ? to replace a single character and * to replace one or multiple characters. By default the system adds the * wildcard pattern to the end of a term to match all entities starting with this term. If you want to search for an exact term, enclose the term in double quotes.
In the result tree either all entities or the entities matching the search term are shown. Expand the result tree to the next level to view the documents where the different entities are found. Double-click on a document icon in the result tree to open the document in the Document editor view.
Right-click on an entity, and click Show related entities to show all related entities in the Entity Browser view. In order to go back, select a previous set of entities from the drop down menu which contains a list of previous actions.
Now the Entity Browser view is updated showing only the related entities to the previously selected one
