专利分析是一个热门的研究课题。然而,设计者不会在早期设计阶段接触专利,因为专利由于其复杂的结构和所使用的法律术语,阅读和理解起来非常耗时。先前的研究已经证明了手动制作专利工作原理的图形表示,以提高设计者对现有技术的认识。本文提出了一种自动化方法,利用自然语言处理(NLP)技术从专利独立权利要求中识别发明工作原理并生成可视化。将这种自动化方法的结果与之前手动生成的示例进行比较。结果表明,自动方法和手动方法之间的匹配率超过 40%,这为进一步开发奠定了良好的基础。比较表明,自动化方法对于明确且一致地表达的特征和关系效果很好,但在应用于复杂句子时开始失去准确性。比较还表明,通过使用经过训练的词性(POS)标记器、改进的解析语法和本体,可以提高所提出的自动化方法的准确性。
Patent analysis is a popular topic of research. However, designers do not engage with patents in the early design stage, as patents are time-consuming to read and understand due to their intricate structure and the legal terminologies used. Manually produced graphical representations of patent working principles for improving designers’ awareness of prior art have been demonstrated in previous research. In this paper, an automated approach is presented, utilising Natural Language Processing (NLP) techniques to identify the invention working principle from the patent independent claims and produce a visualisation. The outcomes of this automated approach are compared with previous manually produced examples. The results indicate over 40% match between the automatic and manual approach, which is a good basis for further development. The comparison suggests that the automated approach works well for features and relationships that are expressed explicitly and consistently but begin to lose accuracy when applied to complex sentences. The comparison also suggests that the accuracy of the proposed automated approach can be improved by using a trained part-of-speech (POS) tagger, improved parsing grammar and an ontology.
