Selecting an entity or link semantic type

About this task

When you choose a semantic type for a specific entity or link type, only those semantic types relevant to that entity or link type are displayed. This filtering is useful when the entity type uses different icons to represent specializations of the type. For example, if you select a Telephone entity type in the query, several Phone semantic types are available.

You might narrow your query to search just cellphones by selecting the Mobile Phone semantic type.

Note: All the ancestors of the semantic type are still displayed, indicating from which more general semantic types the Mobile Phone is type is derived.

Procedure

To select an entity or link semantic type:

1. In a query, right-click an item and select Semantic Type.

2. Select the required semantic type from the tree view.

3. You can widen your search by changing the text that is displayed in Search Available Semantic Types:

   Option	Description
   Shorten the displayed text	"Documents" to "Document"
   Simplify the displayed text	"End date" to "date" or "end"
   Consider alternative spellings	"tire" to " tyre"

4. If none of the semantic types in the Ordered Results area are suitable, you can browse the semantic types that are displayed in the tree view.

5. From the Match Option list select the required option:

   Option	Description

   is exactly	Finds all entity or link types that are assigned the selected semantic type, but not a semantic type descended from it in the hierarchy.
