摘要
SQL语言对数据库的精确查询表现出较佳的性能,但模糊查询却不太令人满意。我们将ROCCHIO反馈算法引入数据库的查询,通过用户的少量反馈同时实现了精确查询和模糊查询。另外,每一次反馈除向用户显示最相关的记录之外,还提供相关度最不确定的记录以加快查询的速率,确保了系统查询的良好性能和用户的满意度。
SQL shows a fine performance in database for exact queries, but not for fuzzy queries. We introduce Rocchio algorithm into database query to achieve both exact queries and fuzzy queries by few feedback. In addition, not only the most correlative records but also the most uncertainty （correlation value with the user query） records will be presented to accelerate the query, which granted the super performance of system and the satisfaction of user.
