| 摘要: |
| 为了更好的理解搜索用户的检索行为,在查询会话基础上分析了用户修改查询的行为规律及用户、查询和点击三者之间的关系.从查询会话的角度,综合考虑了会话中修改的次序、用户、查询和点击等多方面因素,发现了用户修改查询的规律,证明了查询推荐的必要性.统计结果显示:用户修改查询的方式和修改次数有关,而对应的点击数量相对稳定;最终查询一般要比初始查询长,通常是部分替换了初始查询;用户使用搜索引擎的频率越高,修改查询的可能性就越大. |

| Abstract: |
| The session in search engine log denotes a sequential of queries from a user when he is searching for certain information during a period of time.Session analysis is a fundamental work for user behavior analysis.In contrast to current query log analysis focusing on the query modification and the relationship among user,query and clickthrough,this paper presents user behavior analysis based on session,which includes the times of reformulation and the relationship among user,query and click-through.Experimental results show that the way users reformulate queries relates closely to the times they reformulate,while the number of click-through is steady;the last query often gets longer than the first,what is more,the main variation lies in some changed characters;the more often the users use the search engine,the greater the likelihood that they reformulate queries. |
