Method Detail

getRelevantText

Map<String,Integer> getRelevantText(Entity entity)

The method retrieves a string or a set of strings, which is weighted by importance with respect to the entity. For instance, an rdfs:label of an entity can be given more weight than an rdfs:comment, which in turn can be more important than a description retrieved from a web page.

Parameters:

entity - The entity to handle.

Returns:

A weighted set of strings. For a value x, we need to have 0 <= x <= 1.
