【摘要】 通过主题提取进行海洋信息词典的构建,利用已有的向量空间模型进行海洋信息相关度计算,设计了成员引擎的调度方法,并结合主题相关度和邻居协同推荐算法对结果综合排序,搭建了一个面向海洋信息的个性化元搜索引擎。减少了搜索结果的信息量,提高了信息搜索的准确率。更多还原

【Abstract】 The marine information dictionary is constructed through the subject words extracting.The marine-information-related degree is computed by using the space vector algorithm. The scheduling of single search engines is designed. A new personalized rank method based on both subject related degree and a collaborative recommendation algorithm is proposed. Finally, an personalized meta search engine oriented the marine-information is set up. The amount of information search results is reduced and the accuracyof professional information search is improved.更多还原
