摘要:

针对当前目的地选择服务系统机械片面的处理用户的查询请求,提出了采用回答集(ASP)逻辑推理的方式,综合运用旅游常知,情景信息和用户信息来处理用户的查询请求,使得查询结果在精度上有了很大的提高。并对现有的一个ASP推理引擎进行了改进,使其能实现非确定性推理,从而能在目的地选择服务系统中应用。

关键词: 目的地选择, 回答集编程, 推理

Abstract:

Compared with the current destination decision system usually processes user input on the grammatical level, a means for understanding the user input on the pragmatic level by using logic inference engine are proposed. Within a searching context, composed of the common sense of tourism, situation variables and user information, the engine could infer user truly requirement on the pragmatic level. And this inference engine is implemented by doing some alternation to a disjunctive datalog system(DLV)to handle user preferences and desires. The ASP ( answer set programming) can be implemented with the engine.

Key words: destination decision system, answer set programming, reasoning
