| 摘 要： | 为了解决用户兴趣建模初期存在的冷启动问题,以科研用户公开发表的学术产出作为用户兴趣建模的数据源,采用文本挖掘和基于本体的模型表示技术进行用户建模,并提出一种通过实体关系表示用户兴趣的方法。该方法与使用单个关键词或实体的表示方法相比,语义信息更为丰富,能更好地描述用户兴趣。最后,将生成的用户兴趣本体实例存储到Sesame本体数据库中,支持通过SeRQL和SPARQL语言进行查询,实现了用户兴趣信息的语义化存储和检索。

| Abstract: | In order to solve the cold start problem existing at the beginning of user interest modeling, this paper puts the literature published by researchers as the data source of user interest modeling, and applies the technology of text mining and ontology modeling in user modeling, and proposes a method which describes user interest by using entity relationship pair. Compared to the method by using single keyword or entity, this method has more semantic information and can describe user interest better. Finally, the individuals of user interest ontology are stored into the Sesame ontology database and can be queried through SeRQL and SPARQL,and the semantic storage and retrieval of user interest information is implemented. |
