查询词典 iterative computation

Based on the structural-alignment and geometric similarity model, a new approach to Chinese word similarity computation is proposed. By separating the word concept description into two parts of attribute space and case space, which respectively process the structural alignment and calculate the distance of sememes aligned, the word concept similarity is made of the two parts distance with different weight.
