主题模型是一种有效提取大规模文本隐含主题的建模方法。本文将Latent Dirichlet Allocation(LDA)主题模型引入专利内容分析领域,实现专利主题划分,解决以往专利主题分类过于粗泛、时效性差、缺乏科学性等问题。并在原有模型基础上构建LDA机构-主题模型,对专利知识主体和客体联合建模,实现专利主题和机构之间内在关系分析。最后,以通信产业LTE技术领域为例,验证该模型可以有效用于专利主题划分,实现各主题下专利知识主体竞争态势测度。

Topic model is an effective modeling method for extracting implied themes in large- scale text. In this paper, Latent Dirichlet Allocation (LDA) topic model is introduced to patent content analysis for patent theme extraction, which solves the problems in previous patent subject classification, such problems as too rough classifications, lack of time - effectiveness and scientific nature, etc. And then, based on the original LDA model, an extended institution -topic model is developed in this paper. By joint modeling of patent subject and object, the internal relationships between patent themes and corresponding institutions is identified. Finally, a case study is carried out in the LTE technology of the telecommunication industry, and it is found out that these models can be used effectively for patent subject classification and identifying competition situation of patent subjects under each corresponding theme.
