| 摘 要： | 用户兴趣模型的表示是信息检索的核心技术之一.利用潜在语义索引的方法构建了一种用户兴趣模型,通过计算文本与模型的匹配程度,将满足约定条件的文本推荐给用户,并利用相关反馈信息更新用户的兴趣模型.最后通过实验验证了该方法的有效性,实验表明该模型可以很好地提高用户信息检索的效率.

| Abstract: | How to represent the user interest-model is one of the key technologies of information retrieval.In this paper,latent semantic indexing approach is applied in building the user interest-model.First,the document is matched with the interest-model.And then it will be delivered to user according to his constraining conditions.Step by step,the user interest-model will be modified according to the feedback information.At last,the effectiveness of the method is verified through the experiment.It shows that this m... |
