专利检索系统中可视化查询的比较研究

Visualizing Query Comparisons in Patent Retrieval Systems

专利检索是一个非常复杂的过程,用户为了迅速高效地完成检索任务需要得到支持。专利检索过程的许多环节可以借助一些工具完成,其中就包括查询(式)构造工具。查询构造是一项高度依赖人工的任务,工具只能实现对可能有用数据进行预先计算,并针对用户进行可视化。信息检索系统中,查询过程和查询结果可视化的方式有很多。本研究提出了两种典型的原型系统设计,用于在专利检索过程中对不同的查询表达式进行比较。原型包含查询表达式构造因素和结果集大小因素,两种因素对于专利领域专家探究查询表达式的调整对检索效率的影响至关重要。本文开发的系统有助于在专利检索过程中对复杂查询表达式进行逐步优化,系统设计思想基于了领域专家型知识工程。

Patent retrieval is a very complex process where users need to be supported in order to finish their tasks efficiently and effectively. There are many tasks in the process that can benefit from such tools; and one of them the phase of query formulation. Being a highly manual task,it is only able to recompute possible helpful data and to then visualize it for users. The process of querying and the pertaining results of information retrieval systems can be visualized in many ways. We present two prototypical system designs for comparing the queries in patent retrieval. The prototypes include the elements of the query structure as well as the results set size. Both are crucial elements for patent experts to explore the effect of changes in a query. Our system supports the stepwise optimization of complex queries in patent searches. The design ideas are based on knowledge engineering with domain experts.
