利用术语资源改进术语抽取

Improving Term Extraction with Terminological Resources

Sophie Aubin, Thierry Hamon

摘要:

生物医学领域的语料库上的不同术语提取器的研究显示,当应用于高度技术性的文本时,性能下降。难以或不可能将它们定制到新的域是另一个限制。在本文中,我们建议使用外部术语来影响通用语言数据,以提高提取的质量。我们实现的工具利用在不同的步骤的过程中证明的条款:组块,解析和提取候选术语。实验结果表明,使用该方法,可以获得更多的候选项,具有更高的可靠性。我们进一步描述的提取过程中,涉及内源性消歧实施长期提取YaTeA。

英文摘要:

Studies of different term extractors on a corpus of the biomedical domain revealed decreasing performances when applied to highly technical texts. The difficulty or impossibility of customising them to new domains is an additional limitation. In this paper, we propose to use external terminologies to influence generic linguistic data in order to augment the quality of the extraction. The tool we implemented exploits testified terms at different steps of the process: chunking, parsing and extraction of term candidates. Experiments reported here show that, using this method, more term candidates can be acquired with a higher level of reliability. We further describe the extraction process involving endogenous disambiguation implemented in the term extractor YaTeA.
