Abstract:

 Feature words of relation between generalized spatial entities can express these relations and semantics
of them accurately. In order to abstract feature words precisely, firstly, based on location, speech and frequency
of candidate word around entities, this paper defined synthesis supporting probability, aiming at evaluating the
likelihood of becoming feature word. Secondly, a mode for abstracting feature words was proposed. Finally,
experiments were carried on ORG-PER data and LOC-PER data in Sohu news, which achieved a precision about 90%.

Key words: generalized spatial entity, relation abstracting, feature word, candidate word, supporting probability
