Description
Technical field
The present invention relates to print relevant information management and information security field, promptly relate to a kind of text searching method based on document printing.
Background technology
The print management of government, enterprise, army, military project unit, printing security system; The authentication that air exercise print is closed, watermark interpolation, log tracks, audit, statistical study etc. are managed, but for the key message of document printing database trace, the database tap/dip deep into also do not have ripe scheme.Do not have the support of global search technology, in the document printing storehouse of magnanimity, the inquiry of concerning security matters key message, statistic of classification be just as looking for a needle in a haystack, for management, monitoring, the tracking of type information brought very big difficulty.Simultaneously, depth data excavates, the print record of statistical study enterprise, for the corporate strategy development provides decision analysis to have no way of doing it especially.Search technique is widely used in internet environment, promptly to the searching object data source, sets up information database and index data base through processed, thereby response is made in the various retrievals that the user proposes, and required information of user or associated pointers are provided.User's search channel mainly comprises the retrieval of free word full-text search, keyword retrieval, systematic searching and other specific informations.Search technique is that data source is put in order, gives the user information feedback according to customer requirements.The work of search technique mainly divides 3 points; Set up index data base, in index data base, search for and sort, data-base recording is fed back to the user.Index technology is one of core technology of search, to the information of collecting put in order, classification, index to be to produce index database, the Chinese search core is a participle technique.Participle technique is to utilize certain rule and dictionary, is syncopated as a speech in the sentence, and is ready for searching for.Index generates the concordance list that concerns from keyword to the index Resource Unit.Concordance list generally uses the inverted list of certain form, promptly searches corresponding index Resource Unit by index entry.Physical store so that neighbouring relations or closeness relation between the searcher computation index item, and is carried out with specific data structure in the position that concordance list also wants the recording indexes item in document, to occur.Searcher mainly is to retrieve in the inverted list that index forms according to the keyword of user's typing, accomplishes the degree of correlation evaluation between the page and the retrieval simultaneously, the result that will export is sorted, and realize certain user's relevance feedback mechanism.Result for retrieval through search engine obtains is often hundreds and thousands of, and in order to obtain Useful Information, technology commonly used is to grade to search unit by the importance of search unit or correlativity, carries out relevance ranking.The degree of correlation here is meant the amount that search key occurs in document.When amount is high more, think that then the degree of correlation of the document is high more.Existing search technique is widely used in internet, e-book, sector application system etc., but also is blank to print management, the application of printing security system.In realizing process of the present invention; The inventor finds that existing print system focus rests on authentication, document printing management, the tracking of document printing closed loop, document printing statistical study more, but does not realize to data search, the statistical study of document printing data key message of document printing.
Summary of the invention
The present invention aims to provide a kind of text searching method based on document printing; Can solve in the existing system problem that does not have tap/dip deep into to document printing storehouse key message, cause the security files safe early warning inadequately comprehensively, do not have perfect data statistic analysis, the document of divulging a secret is traced inadequately thoroughly, the security files statistics is not accurate enough.Based on the realization of the text searching method of document printing, for place mat has been carried out in the intellectuality of print system.
A kind of text searching method based on document printing comprises: print What literal extraction module is used for extracting the Word message of document printing, as the data source of full-text search; Search engine module is used for user's typing key message is searched for, analyzed, and Search Results is fed back to the user.
Preferably, said print What literal extraction module comprises: print out task is intercepted and captured the unit, is used to intercept and capture all print out task, prepares for extracting the document printing content; Extract the word content unit, be used to extract the word content of document printing; Preserve the word content unit, be used for the word content that extracts is saved in the file, so that carry out full-text search.
Preferably, said search engine module comprises: search UI unit, be used for user interactions, and receive the search condition of user's typing, and display of search results; The index unit, being used for the document printing is the basis, is unit with every part of document printing, extracts the index entry of this document printing and records in the index data base; The searcher unit is used for the retrieval according to the user, in index database, finds out document printing, carries out degree of correlation coupling, search relevance printing matching document searching result.
Preferably, search UI unit comprises hunting zone setting, keyword setting, keyword search, Search Results ordering, print out task search result list display unit; The user is in hunting zone information such as UI page input types of organization, personal information, document security level, document purposes, time-write intervals; Keyword according to this inquiry; Submit to search engine to search for hunting zone setting, key word information; Search Results according to search engine shows ordering to Search Results, and the print out task list information is shown to the user the most at last; The user can carry out flexible configuration to the detailed row of printing the task list demonstration, with the print job information of explicit user care.
Preferably, said index unit is according to the document printing Word message that extracts, and the document printing information representation is a kind of mode of being convenient to retrieve and is stored in the concordance list that generates document library in the index data base; Look for corresponding document printing by index entry, in the time of with document printing set ordering storage a sorted lists of keywords is arranged, be used to store the mapping relations concordance list of keyword to document printing.
Preferably, said searcher unit is the inquiry according to the user, in index database, finds out relevant document printing, prints the degree of correlation evaluation of document and inquiry, returns to meet the document printing set of setting threshold values.
In such scheme; Literal through to document printing extracts; Word content to document printing is set up index; To the keyword message that the user is concerned about, can search for, add up, analyze relevant document printing, overcome in the existing method for comprehensive retrieval of document printing keyword message, the deficient phenomena of macromethod.Cause enterprises and institutions for the document content in document printing storehouse can't be comprehensively, three-dimensional, depth analysis; The content investigation of document of divulging a secret has been brought very big difficulty; Simultaneously because not to the document library tap/dip deep into, also lack data support and theoretical direction for the decision-making of unit classified information management and control from now on.
