面向技术机会发现TOD的专利信息抽取*——韩国科学技术信息研究院KISTI语义服务

技术机会发现(TOD,Technology Opportunity Discovery)是面向新技术进行监测，并提供机会的一种服务；所谓“基于专利的信息”是指采用自然语言技术对专利进行抽取的结果。本研究的目标资源覆盖过去20年间发表的所有专利，目标信息则是其中产品名称及其部分-整体关系(Part-of relations)。应用基于词典和相似度的命名实体识别、基于模式的关系抽取、以及基于机器学习的信息过滤几项技术，本研究取得了令人鼓舞的效果。

Patent Information Extraction for Technology Opportunity Discovery

Technology Opportunity Discovery is a service to detect and provide opportunities for the new technologies. Patent-based information is extracted by natural language processing techniques. All patents published during the past 20 years are target resources and product names and their Part-of relations are target information. A dictionary and similarity-based named entity recognition, a pattern-based relation extraction, and a machine learning-based filtering have been used and showed an encouraging performance.
