Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is made the most in detail
Describe.Following example are used for illustrating the present invention, but are not limited to the scope of the present invention.
The information retrieval method of embodiments of the invention includes as shown in Figure 1:
Step S110, parses inquiry tag, institute from the demand information that information inquiry side issues
State inquiry tag and represent the demand condition of demand information.Described inquiry tag is mark set in advance
Signing the label in list, set some labels in described list of labels, each label belongs to not
Same classification, such as: product or service item are retrieved, the label bag in described list of labels
Include: in industry label, role's label, area label, department's label and academic title's label classification
At least one.
Certainly, before performing this step 110, the demand information of the issue of information inquiry side is obtained
Take, in the present embodiment, receive the label that information inquiry side selects from described list of labels, and
Generate the demand information comprising selected label by predetermined format, selected label is described inquiry
Label.Wherein, predetermined format is such as: I to look for " gift toy " industry of " Chinese "
" down toy (teddy bear) " " supplier "；I to get in touch with the " main of " market survey " department
Seat ".Wherein, the text in quotation marks is label, and the text outside quotation marks is predetermined word statement
Display format.
Step S120, by the supply label of described inquiry tag with the information providing prestored
Mate, the information provision matched with demand information with retrieval.Wherein, supply label list
Showing the feature of the information provision that information providing issues, supply label is also label set in advance
Label in list.
During coupling, the value by each inquiry tag in demand information is identical with described inquiry tag
The value of the supply label of classification compares, if the value of inquiry tag and the value phase of supply label
With, or the scope represented by the value of inquiry tag can cover represented by the value of described supply label
Scope (such as: the value of the regional label in inquiry tag be China, supply label in area
The value of label is Beijing), then match hit, if the inquiry tag in demand information is to supply letter
The hit rate of the supply label of breath reaches predetermined value, the most described demand information and information provision coupling
Success.Hit rate predetermined value to be reached sets according to practical situation, if requiring high precision,
Hit rate may be provided at more than 80%, and even 100% so that it is mate completely.Preferably, hit
Rate can arrange ad hoc rules, such as: must hit " industry " classification.
Certainly, before performing this step 120, the information provision of the issue of information providing is obtained
Take, in the present embodiment, receive the label that described information providing selects from described list of labels,
And (similar with demand information, including label text, predetermined word statement shows to press predetermined format
Show text) generate the information provision comprising selected label and store, selected label is described
Supply label.

Before entering) in label, it is also possible to be User Defined label, or both have concurrently.
Such as: retrieving for product or service item, demand information and information provision are data base
In relevant storage field include: ID (UserID), industry (industrycategory)
Tag identifier, role (rolecategory) tag identifier, area (areacategory) label
Mark, department (departmentcategory) tag identifier, position (jobcategory) mark
Sign mark.Above-mentioned all marks can consist of demand, an information provision content completely.Often
Individual user will have a plurality of different demand, information provision data, this type of information cluster for
Same type demand information carries out matching operation.This message trunking can persistence, and for real
Time coupling, to reach the pairing of optimum label.
Step S130, returns to information inquiry side by the information provision matched with demand information.
Further, the information provision issued due to information provider is probably employing different language
(such as: English, French etc.), in order to more retrieve more effective information, described parsing
Also include before inquiry tag: demand information is translated as different from described demand information original language
At least one language.Preferably, it is also possible to translate into several languages set in advance.Translation
Being divided into two parts, a part is the translation of label, and one is the translation that word statement shows.By
The content and the form that show in word statement are more fixing, and the translation that therefore word statement shows is led to
Cross resource bag to realize.Here the main translation introducing lower label (Tag).
Tag has a Tag table, and comprising TagID TagName, TagID is Tag mark,
TagName is the Tag title of default language.
When needs negated default language Tag word content, need to inquire about Tag_Translate table
Field has ItemID [mark] TagID [Tag mark] TagViewName [Tag display Name]
Language [language]
Content after query translation is to be acquired by Tag mark inquiry Tag_Translate table
Content after translation, if without translation, taking Tag default language title.
Further, each label in described list of labels is equipped with predetermined weight, coupling
Time mate successively by label weight size, in the range of the tag match that weight is bigger, mate power again
The label that weight is less.Such as: when the label chosen in demand information includes industry label, should
The weighted value of label is first-selected weight, needs on the basis meeting the sector label, then goes
Mate other label.The weight of label can select label from list of labels in information inquiry side
Time be set according to self different demand.
Further, in order to provide more information to information inquiry side so that it is there is bigger choosing
Selecting property, step S120 specifically includes:
After once coupling, it is judged that what described inquiry tag matched supplies the confession that label is corresponding
Answer information content whether less than predetermined quantity, such as 10 information provision records, if being less than, then
Reduce the number of described inquiry tag or reduce hit rate predetermined value, and by the inquiry mark after reducing
Re-start coupling after signing or reducing hit rate predetermined value, i.e. carry out fuzzy matching.Such as: only
Choose " the industry label ", " role's label " in inquiry tag and " area label ", just may be used
The matching result that the scope that searches is bigger.
In order to take into account the precision of inquiry in the case of hunting zone is bigger simultaneously, it is preferable that
The weight of the inquiry tag after described minimizing is more than or equal to the weight of the inquiry tag being reduced.
Further, step S130 specifically includes: by height or the coupling mark of described hit rate
The comprehensive weight size the signed information provision sequence to matching；Information provision after sequence is returned
Back to described information inquiry side.With facilitate information inquiry side on the information provision page returned fast
Speed positions oneself required information.
