Wherein, described cloud storage system can use existing various cloud storage system to realize, does not give unnecessary details here.
Step 202: the participle dictionary according to default electric power thesaurus carries out word segmentation processing to each document in the electric power data storehouse, the word segmentation result that obtains is stored according to arranging structure, constitute index data base, described index data base is stored in the cloud storage system.
Comprise in the described index data base: lexical item and this comprise the collection of document of the document formation of this lexical item.Wherein, can only put down in writing the document information of document correspondence in the described collection of document, for example document identification (ID) and/or document title etc.
Wherein, according to the participle dictionary of default electric power thesaurus each document in the electric power data storehouse being carried out word segmentation processing comprises:
To treat that successively each entry in the character string and participle dictionary mates in the participle document,, then store the information of this entry and entry correspondence, proceed the coupling of this entry successive character string again, up to the document end if on the coupling.
The word segmentation result of carrying out obtaining after the word segmentation processing is just to arrange structure, and word segmentation result is a main fields with the document, has write down the lexical item that comprises in each document, that is to say: the corresponding lexical item set that is made of lexical item that the document comprises of each document.Arranging structure is main fields with the lexical item then, has write down all documents that comprise lexical item, that is to say: the corresponding collection of document that is made of all documents that comprise this lexical item of each lexical item.For example, just arranging structure is to comprise: document 1, lexical item set { t1, t2, t3}; Document 2, lexical item set { t1, t2, t4}; The structure of arranging of its correspondence then is: lexical item t1, collection of document 1,2}; Lexical item t2, collection of document 1,2}; Lexical item t3, collection of document { 1}; Lexical item t4, collection of document { 2}.
Step 203: obtain the retrieving information of user's input, according to the keyword of described retrieving information deterministic retrieval information, and the logical relation between the keyword.
Wherein, the retrieving information of user input can be entry or statement, at this moment, generally needs the keyword by the mode deterministic retrieval information of participle, and concrete segmenting method is not given unnecessary details here.At this moment, generally need with in the word segmentation result for example " " " " etc. the lexical item that retrieval not have to help is deleted, concrete, can set in advance the dictionary that to delete, by the lexical item in the lexical item behind the participle and this dictionary is compared, thereby obtain the keyword of final retrieving information correspondence.At this moment, the logical relation between the keyword can for: comprise all keywords in the document.
Perhaps, also can set in advance the how rule of retrieving information of user, for example, set need between the different search keys by logical connective " and " " or " " * " "? " or the like indicate logical relation between the keyword, at this moment, directly the keyword of the lexical item between adjacent two conjunctions as retrieving information got final product.At this moment, the logical relation between the keyword can be determined by the logical connective in the retrieving information.
Wherein, the relation of each conjunction representative can independently be set, and is general, and in actual applications, the implication of various conjunctions is as follows:
