摘要 在2005年863信息检索评测中,我们主要尝试了采用入链接描述文字。以及我们在去年已使用的词对检索方法。由于只能提交一组自动方法检索的结果。我们的手工查询以及自动处理查询两组结果,都采用了比较稳定的词对检索参数。以及有比较一致的良好效果的八链接描述方法。就我们在自己构建的训练集以及提交的两组结果的实际效果的评测来看,我们的方法对用户查询词的精确性有比较高的要求,并且词对和入链接描述文字都能提高检索的效果。 In the IR evaluation of 2005, we tried to include information from in-link anchor texts and word-palr to improve retrieval performance. The two runs we submitted were one with automatic query processing and one with manual query editing. We chose the most stable and effective method for the two runs: word-pair with a stable parameter and in-link anchor included in the documents. As results from our training topics and from evaluations of the submitted two rims show, our method requires an accurate user query to achieve high performance, and the word-pair together with in-link anchor are effective retrieval methods.
