Semantic relation identification

Semantic relation identification: examining relations between lexical items in a sentence. The task, given a sample of semantic relation types, is to identify and classify semantic relations between nominals (i.e., nouns and base noun phrases, excluding named entities); a main purpose of this task is to assess different classification methods. Another task is, given a sentence and two tagged nominals, to predict the relation between those nominals and the direction of the relation.
