The keyword extraction method comprises the steps of: text-mining each of a plurality of technical documents to generate a document-term matrix in which term frequency (TF) of each of a plurality of terms included in each of the technical documents is used as an element; determining a first...
TextRank: Bringing Order into Texts 2. Rake算法 算法原理 Rake是Rapid Automatic keyword extraction的简称,它通过给每个候选的关键词打分,然后排序,得到最后的关键词。其原理是通过累加关键词中每个字的得分来求该关键词的得分,而每个字的得分由该字的度/该字的词频得到。每个字的度是指该字与文档中所有字在候...
Keywords are of benefit to many text mining applications. However, a large number of documents do not have keywords and thus it is necessary to assign keywords before enjoying the benefit from it. Several research efforts have been done on keyword extraction. These methods make use of the ‘...
