Semantic vector types

After processing with TextChart, the terms in a document are associated with one or more semantic vectors. An LxBase defines each semantic vector as one of the following: an entity, a no-output entity, a part of speech, pragmatic, or relational.

• Entities

  A term that's associated with an entity semantic vector such as PERSON, ORG, or PLACE is extracted as an entity and included in the output.

• No-output entities

  A term that's associated with a no-output entity semantic vector is extracted as an entity but is not included in the output.

  By changing a semantic vector from "entity" to "no-output entity", you can prevent entities of the affected type from appearing in the output.

• Parts of speech

  A term that's associated with a part-of-speech semantic vector has been identified as a part of speech, such as a verb or an adjective.

• Pragmatic

  A term that's associated with a pragmatic semantic vector has been identified as belonging to a pragmatic category such as "given name" or "possible identification number".

• Relational

  A term that's associated with a relational semantic vector such as "interviewed" or "identified as" is used as the predicate in a predicate-subject-object (PSO) relationship.
