【摘要】 针对当前目的地选择服务系统机械片面地理解用户的查询请求,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处理用户的查询请求,使查询结果在精度上有了很大的提高．同时对现有的一个ASP推理引擎进行了改进,使其能实现非确定性推理,并应用于目的地选择服务系统中．更多还原

【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 on top of a disjunctive datalog system (DLV) to handle user preferences and desires. The answer set programming (ASP) can be implemented with the engine.更多还原
