Demand information.For example, released news in the network platform in the presence of two：（A）Supply trendy Nokia's smart mobile phone；（B）Supply
Nokia's battery of mobile phone.When information search user is scanned for by the use of " mobile phone " as search term, the inspection of engine is generally searched for
Rope logic uses literal hit and matching process, it is thus determined that this two release news it is all related to the search term, so this two
Bar information can all be called back.However, actually only have（A）It is the demand for meeting information search user,（B）Searched for the information
It is irrelevant information for rope user, such search degree of accuracy is relatively low, it is impossible to meets user's request well.
Such to solve the problems, such as, search engine is typically released news come in identifying that this releases news by analysis at present
Core presentive word or core product word（Referred to as core word）, and recall as search engine the correlation calculations of result
Foundation, rather than released news by whole piece and carry out literal hit to the search term of information search user and match related to determine
Property, literal matching thus can be reduced to a certain extent and the incoherent information of meaning is recalled.
In such method, identifying the usual way of core word is, releasing news point for user is issued to information
Word processing and part-of-speech tagging, according to pre-prepd part of speech or attribute dictionary matching, are labeled, Huo Zhetong to releasing news
Machine learning method automatic marking part of speech or attribute are crossed, then basis will such as be labeled as the word of noun as core word etc
Pre-defined rule, identify the core word that this releases news.
For those describe it is lack of standardization or more description information release news, may will recognise that by this method
Multiple core words.For example, release news " to supply trendy notebook computer, 500G hard disks, 4G internal memories, 15 cun of liquid crystal displays
Device ", " notebook computer ", " hard disk ", " internal memory " and " liquid crystal display " can be all identified as by core word by the above method.
Under such circumstances, it will usually according to such as TF-IDF（Term frequency-inverse document frequency,
Word frequency-anti-document frequency）Etc method identify importance of these core words in this releases news, then according to core
The importance of word determines correlation that this releases news with search term, and is shown and search term phase according to relevance ranking
What is closed releases news.
However, the inventors discovered that, in the case of this multiple core words, i.e. release news description it is lack of standardization or
