摘要： 元搜索引擎中采用Borda投票法，根据位置关系采取线性递减的规则为结果机械地分配相关分值，会影响排序结果。针对该不足，提出一种Borda投票的改进算法，计算查询串与各个结果之间的相似度，并将相似度作为该结果的相关分值。实验结果证明，改进算法的查准率优于Borda投票法。

Abstract: Borda voting method is adopted in meta search engine. It is based on the relationship between position taken by the linear decrease in the allocation of the relevant rules to score the results. Mechanical distribution of scores affect the results of the sort. According to its default, this paper presents an improved Borda voting algorithm, which calculates the similarity of query string with each result and similarity as the result of the relevant scores. Experimental results show that the precision of improved algorithm is better than Borda voting method.
