语义树 meaning in English

semantic tree

Test result shows that compared with traditional similarity model of word frequency , the weighted semantic similarity model improves the precision obviously
实验表明，本文提出的基于语义树的加权语义相似度模型与传统的词频相似度模型相比，准确率有明显提高。
First , the question answering system calculates semantic similarity by using distance between words in semantic tree and the height of semantic tree , then this system uses semantic similarity between words and the weight of word to calculate semantic similarity between users ' questions and questions in answer database
首先，利用语义树中词语间的距离和语义树的高度来计算词语间的语义相似度，然后利用词语间的语义相似度和词语的权重进一步计算用户问题与答案库中问题间的语义相似度。
