Automatic understanding of natural language problems is a long-standing challenge research problem in automatic solving. This paper models the understanding of geometry questions as a problem of relation extraction, instead of as the problem of semantic understanding of natural language;further it discovers that the entities and the geometric attribute pattern of elements can play an important role in relation extraction. Based on these ideas this paper proposes a syntax-semantics (S2) model approach to understand geometry problem, targeting to produce a group of relations to represent the giv...
