开放知识库构建技术的多维量化评价方法

Multi-dimensional Quantitative Evaluation Method of Open Knowledge Base Construction Technology

网络大数据时代的到来使得开放知识库的构建技术越来越受到学术界和工业界的关注。近年来,依托开放知识库构建技术而构建的知识库及相关应用层出不穷。然而,目前并没有一种较为统一、全面的开放知识库构建技术的多维量化评价方法。在已有工作的基础之上,提出了一套开放知识库构建技术的多维评价指标体系,综合考虑包括开放知识库的构建准确率、构建时间、构建规模在内的多个维度,并在此基础上提出了开放知识库构建技术的多维量化评价方法。实验表明,开放知识库构建技术的评价结果较传统的评价方法更为全面、合理,并且可以根据实际应用中维度的重要性差异产生不同角度的评价结果。

With the coming of the era of network big data,the construction of open knowledge base attracts more andmore attention from both academia and industry.ln recent years,the applications based on open knowledge base construction technologies are emerging in an endless stream.However,there is no unified and comprehensive multi-dimensionalquantitative evaluation method which evaluates the construction technique of the open knowledge base.Based on existing work,the multi-dimensional specification system of open knowledge base construction technique was put forward,which combines three dimensions,i.e.,the accuracy,the construction time,and the scale of a knowledge base.Furthermore,a multi-dimensional quantitative evaluation method was proposed to evaluate a group of open knowledgebase construction techniques.Experiments show the rationality and comprehensiveness of the proposed evaluation method,and it can deduce different results to meet the demand of different applications according to the importance of the dimensions.
