摘要:

关键词注释是识别表示文档主要内容的文本单元的任务。关键词注释可以通过从文档中提取最重要的短语(关键词提取)或通过从受控的特定领域词汇表中分配条目(关键词分配)来执行。分配方法通常更可靠。它们提供了格式更好的关键短语,以及文档中没有出现的关键短语。但是,与不依赖于手动构建资源的提取方法相反,它们通常是沉默的。本文提出了一种新的方法,执行关键词提取和关键词分配在一个集成和相互加强的方式。在涵盖人文社会科学不同领域的数据集上进行了实验。与关键词提取和关键词分配最先进的方法相比,它们在统计上有显着的改进。

英文摘要:

Keyphrase annotation is the task of identifying textual units that represent the main content of a document. Keyphrase annotation is either carried out by extracting the most important phrases from a document, keyphrase extraction, or by assigning entries from a controlled domain-specific vocabulary, keyphrase assignment. Assignment methods are generally more reliable. They provide better-formed keyphrases, as well as keyphrases that do not occur in the document. But they are often silent on the contrary of extraction methods that do not depend on manually built resources. This paper proposes a new method to perform both keyphrase extraction and keyphrase assignment in an integrated and mutual reinforcing manner. Experiments have been carried out on datasets covering different domains of humanities and social sciences. They show statistically significant improvements compared to both keyphrase extraction and keyphrase assignment state-of-the art methods.
