Examples
- Then , shallow technologies of nlp used in this paper are introduced
其次介绍了文本过滤技术，并分析了常用的rocchio模型的特点。 - Then the threads in segmenting document into different topic is introduced , which includes statistical methods and semantic network . then , the rocchio model characteristics in text filter are analyzed
然后，介绍了根据不同线索将文本中不同子主题切分的技术，这些线索包括词义网络和各个段落关键词出现的频率统计，并指出它们各自的优缺点。 - This method effectively shield the learning process from plenty of feedback noises produced by distorted threshold and sparseness of initial information , and also imitate artificial feedback approximately to perfect the intelligence of adaptive learning mechanism
此外,选择聚类择优后的一类信息参与rocchio自适应学习与更新,能够有效地削弱阈值偏见性和伪相关反馈排序偏见性造成的负面影响。 - The learning algorithms to build user profile are the hot point in the current researches of information filtering . cluster algorithm integrates the advantages of rocchio and knn . but conventional cluster algorithms cannot embody the different interests of users
用户兴趣特征的学习算法是目前信息过滤研究的热点，聚类算法综合了目前流行的两类算法rochio和knn的优点，但传统的聚类算法不能体现用户对文档的不同兴趣度。 - To fulfill the requirement and characteristics of this track , which include paragraph - based and a relevant document supplied by user before retrieval , the rocchio model and vector model are merged to compute relevance between query and document . then , gradient decrease method is used to train the parameters of rocchio model . then , based on the paragraph - level relevance , the sorted documents are returned
本文针对文本检索大会子项目的要求和基于段落的，用户查询时可能提供一篇相关文章的查询特点，首先将rocchio模型和向量空间算法结合起来来把握用户需求并计算文档与查询的相关度，再使用梯度下降技术来训练模型中的参数，最后依据查询和段落层的相关度，使用基于段落切分的方法返回包含用户查询最相关文章。
