The invention discloses a
label automatic generation method based on a meta-
search engine. The method comprises the steps that firstly, text preprocessing optimization is conducted,
Chinese word segmentation is conducted and meanwhile, basis information of words is saved and the basic information comprises
part of speech, word position, word frequency of which quintuple is composed; secondly, the words are filtered, stop words are removed,
part of speech filtration is conducted, and according to experience,
noun,
verb and gerund are kept and
noise disturbance is reduced; word
information quantity is recalculated again, by counting the word basic information, word position
score, word frequency and word span are calculated and comprehensive
score is calculated as weight of the words; finally, the similarity between words is calculated as edge weight in TextRank
algorithm and the TextRank
algorithm is used for calculating TextRank value of each word. According to the
label automatic generation method based on the meta-
search engine, the meta-
search engine technology and automatic generation
label are used, the automatic label technology is applied to the search engine and therefore recall ratio and precision ratio are guaranteed.
