摘要：针对元搜索引擎返回结果无序的问题，提出了运用特征模板的模糊积分算法来辅助实现文档评价的排序，以“个性化旅游服务平台”为实验基础平台，运用元搜索与垂直搜索相结合的方法，验证了该种改进后的结果融合模型的可行性及其优势。实验结果表明，该方法既能很好地体现文档的行业特性，又能很好地体现文档中特征向量与特征向量之间的相互关系对文档评价的影响。

Abstract: Aiming at the disorder problem of results from the metasearch engine, the fuzzy integral algorithm using feature template was adopted to achieve aided sort of documents evaluation. Combining metasearch and verticalsearch, the platform of “personalized tourist service”was used to verify the applicable and advantage of the improved results combining model. The experimental results show that the method finely realizes not only the industry characters of the documents, but also the impact to the documents evaluation with the relationship among characteristics vectors.
Key words: fuzzy integral; metasearch engine; vertical search; feature template; characteristics vectors
