A computation study on semantics based weighted sentence similarity
ABSTRACT:
Semantic similarity is the essential part of automatic
question answering system, and the computation of semantic similarity based on
ontology can provide more various semantic information compared with the
traditional method. In this paper, we firstly propose a semantic similarity
algorithm used in the sentence similarity computation, combining relations of
semantics, hierarchical structure and depth. Next, based on conventional
sentence similarity algorithm, we develop a weighted sentence similarity
algorithm. Finally, a question answering system is implemented with the two
proposed algorithms. The experimental results show that our proposed method can
achieve higher accuracy than others.
