New Dataset: Semantic Roles and Case Frames Dataset: LHB Edition

Rick Brannan (Logos)

What is it?

Grammatical annotation (subject, direct object, etc.) only denotes the grammatical function an item fills in a given clause. However, semantic roles annotate a text for what an entity is doing or having done to it no matter what its grammatical function. A subject could be an Agent (the entity doing something) or an Experiencer (the entity having something done to it). Marking the semantic role makes meaning-based searching possible.

How does it work? 

Practically, this means that instead of searching for where David is the subject of a clause, one can focus the search for where David is the Agent. When this is combined with Logos' participant analysis and referent analysis it means the instances where pronouns refer to David as Agent or where verb morphology implies David as Agent are located as well.
