摘要
知识检索过程必须借助于语言工具来实现,这一过程在用户同系统知识库的交互中,表现为知识→语言→知识→……的互相转换过程。在知识检索中普遍存在语境支持等语用现象,这些现象尤其集中存在于人机交互的检索界面,而其中的锚文本等及其分布构成了检索交流中重要的语境支持信息。知识检索系统界面的语用设计直接决定了系统检索的成效。系统界面及锚文本的语用设计的基本要求包括语境充分和整体优化等。
Knowledge retrieval process must be achieved by means of language tools,in the human-computer interaction,this process is represented as mutual conversion process such as knowledge → language → knowledge →…….The pragmatic phenomena such as context support exist widely in knowledge retrieval.These phenomena are particularly concentrated in the retrieval interface of human-computer interaction,while the anchor text and its distribution form the important context support information in knowledge retrieval process.The pragmatic design of the knowledge retrieval system interface directly determines the effectiveness of the retrieval system.The basic requirement for the pragmatic design of the system interface and the anchor text includes the full context and overall optimization.
