Automatic Generation of Patentmaps from Patent Documents by Extraction of Expressions using Bootstrapping

从专利文献中获取技术词和有效词是有用的，例如，它可以应用于专利地图的自动生成。因此，我们首先提出了一种自动生成专利地图的方法，从专利文献中提取的表达式，使用交叉自举。然后提出了一种结合语法模式和引导法的方法，利用线索词来获取这些词。我们开发了一种方法来详细分析要提取的对象自动专利地图生成。

Technical words and effective words acquisition from the patent document is useful, for example, it can be applied to automatic generation of patent map. Therefore, we first propose an automatic generation method of patentmaps from patent documents by extraction of expressions using cross-bootstrapping. Then we propose a method to a combination of grammar patterns and bootstrap method using the clue word,to obtain these words. We develop a method to analyze in detail the object to be extracted for automatic patent map generation.
