Description
Technical field
The present invention relates to bidding field, more particularly to a kind of acquisition method of information on bidding.
Background technology
Bid is a kind of commonly used in the world, organized market trading activity with bid, is engineering, cargo or clothes
The dealing of business trade.Typically purchaser offers and requires in advance, and numerous trading objects is invited to participate in competition simultaneously
Conclusion of the business person is therefrom selected according to the program of regulation.Bidding activity to break trade monopoly and barriers between the regions, increase economic efficiency,

Want means.
Information-based development brings the new situation in bidding field, and originally bidder mainly obtains item by periodicals and magazines
The mode of mesh bidding information is transformed to obtains the information for being suitble to oneself to submit a tender by internet site.One kind of bidder
Way is to log in each bidding website of various regions to obtain information, and then being retrieved and being investigated one by one by artificial mode needs
The information wanted.Another more efficient way is to log in some large-scale bidding information sites, passes through full-text search
The bidding information that mode removal search needs.
However, this mode takes time and effort, while the included search of bidding website cannot guarantee that quality, this is resulted in
Mistake misses important information.And by logging in large-scale bidding information site, it is gone by way of full-text search
Search for the bidding information needed, it is matched of low quality also due to use fuzzy matching algorithm, caused by the nothing that searches out
It imitates data and is more than valid data, more frighteningly miss more valuable informations.
Invention content
To solve the above-mentioned problems, the present invention provides a kind of acquisition methods of information on bidding, including step：
S100 information on bidding) is acquired：Using each bid net as information source, the web data of information on bidding bulletin is obtained, then
Web crawlers is transferred to carry out information collection this web data；
S200 information on bidding) is extracted：Advertisement in the web data of web crawlers acquisition, friendly link are filtered out, so
The effective information in web data is extracted afterwards, and each information defines an index, all index compositions indicator lists；
S300 information on bidding) is stored：Effective information uses the table in database to store, each index extracted uses
A row storage in structured database, web data, bidding information medium source, affiliated area, the industry, webpage are sent out
Cloth time, web retrieval time are also stored in the row of database one respectively as index.
Preferably, the step S100 acquisitions information on bidding further includes the screening of web data：Information on bidding is not timing
Publication, the frequency acquisition of web crawlers can be higher than the newer maximum frequency of information on bidding, and acquisition is will appear in gatherer process
To the situation of duplicate message；Web crawlers judges the address for the web data to be acquired the information with address only needs
Acquisition is primary.
Preferably, the information collection frequency of the web crawlers is once a day.
Preferably, the effective information includes：Project name, project number, bid the time, submit a tender the time, the place of the bid submission,
Open bid time, opening of bid place, budget amount, procurement unit, procurement unit contact person, procurement unit's contact method, procurement unit
Address, agency, agency contact person, agency's contact method, agency address, buying content, attachment documents.
Preferably, the database can be any one in Access, sql server, mysql and oracle.
Beneficial effects of the present invention are：The present invention provides a kind of acquisition methods of information on bidding, select all kinds of bid nets
It is information source to stand, and is acquired to webpage information using web crawlers, and extract effective information and stored, and bid letter is improved
The acquisition quality and efficiency of breath.
