摘要: 在电子商务网站中，关键字搜索是用户查询商品的一种重要手段，其中计算检索串中的切词权重则是搜索引擎查询处理时的一个重要步骤.本文总结了现有计算切词权重方法的不足，提出了一种新方法.该方法结合切词重要性和相关性确定切词权重，有效地提高了切词权重确定的准确性，是一种切实可行的计算切词权重的方法.Abstract: In most E-commerce web sites, key word search is an important way for users to find commodities, and calculation of the term weights is a major step for search engine to process queries.
