基于双语词典和歧义消解的中英双语专利信息检索研究

Research on Chinese-English Bilingual Patent Information Retrieval Based on Bilingual Dictionary and Disambiguation

[目的/意义]为了增进知识交流、知识共享,避免专利侵权,研究了基于双语词典和歧义消解的中英双语专利信息检索方案,并将其应用到实际系统开发中。[方法/过程]通过基于双语词典的提问式翻译实现双语专利检索,利用基于潜语义分析的提问式消歧策略进行歧义消解,结合布尔检索模型与向量空间模型构建检索表达式,与专利索引库进行匹配,生成检索结果。[结果/结论]选取"3D打印"领域中英双语专利语料为样本,通过检索实验证明方案的有效性。

[ Purpose/significance ] In order to enhance knowledge communication and knowledge sharing, as well as to avoid patent infringement, this paper studies the Chinese-English bilingual patent information retrieval scheme based on bilingual diction- ary and disambiguation, and applies it to develop systems. ~ Method/process ] The paper uses the meth^d of query translation based on bilingual dictionary to achieve retrieval, resolves ambiguity based on latent semantic analysis of disambiguation strategy, and combines with boolean retrieval model and vector space model to build retrieval expression. Then the paper matches the patent index database to generate the retrieval results. [ Result/conclusion ] The Chinese-English bilingual patent corpus in the field of ＂3D printing＂ is chosen as the sample, which proves the effectiveness of the scheme by searching experiment.
