Description
Technical field
The present invention relates to a kind of method of carrying out a plurality of Search engine retrievals simultaneously, refer to a kind of network data system that is applied to especially,, can obtain the method for many website information simultaneously by the input key word and/or after setting search argument.
Background technology
Along with the develop rapidly of internet (Internet), the information on the network is also more and more abundant, and also has every day new website to add.Because information content is huge, allows the user look for information just as looking for a needle in a haystack on internet, knows that required information necessarily exists perfectly well, but wants oneself to go for, and but almost has no way of doing it.Therefore, the user retrieves from the website of some internet Search engines (Search Engine) usually seriatim.
The internet Search engine be a kind of in internet active searching information and with the website of its automatic index, it is day and night walked on internet so that constantly seek new webpage, and the individual character in its each page that retrieves of index, its index content is stored in can be in the large database of inquiring about; This class Search engine is a lot of now, as Yahoo, and Infoseek, Altavista etc.
It is in will be on the internet immense information ocean, to find the needed information of user that the user utilizes the purpose of Search engine; The user usually and pay no attention to result that Search engine returns have on earth what, what be concerned about is whether these Search engines can lead the place of wanting to it to the user, thereby obtains valuable information; Therefore, the user wishes that Search engine can really return its needed result
But each Search engine is all searched independently on the net, because their retrieval mode differences separately, the scope that the station data that they search is contained also has nothing in common with each other; The data directory mode of each Search engine is also each has something to recommend him, has plenty of by the mode that is similar to index list in the library and carries out category index, as Yahoo; And what have is to carry out index by each word that occurs in the webpage, as OpenText.Even also have the Search engine of special certain category information of search, if any special patent searching information, special retrieval shareware is arranged also.
When utilizing these Search engines to search information, traditional search method is to open a browser (Browser) earlier, as the Interner Explorer of Microsoft or the Netscape Navigator of Netscape, find the homepage (Home Page) of certain Search engine, in its homepage, key in the key word (Keyword) that to inquire about, need set some options (parameter) in case of necessity, as return what results, the scope of retrieval etc.; Search engine will be inquired about in its database then, and the result that will retrieve is back to browser; If the result of the dissatisfied retrieval of user repeats above-mentioned step till satisfaction just can move to the homepage of another Search engine again.
For example, if want to use the Yahoo Search engine to remove to seek the website of some relevant calculation machine magazines, must open the Netscape Navigator of Netscape earlier, in its homepage, key feeding key words " computermagazine " is pressed Search (searching) button, as shown in Figure 1; Then, the Yahoo Search engine will return the relevant data of many PC Magazine, as shown in Figure 2, if utilize the Infoseek Search engine to inquire about computer magazine (PC Magazine) equally, the result that its inquiry is returned is different with the Yahoo Search engine just, as shown in Figure 3.
Just because of this, retrieve in different Search engines with same key word, resulting result is different often, each Search engine all can return it think the coupling the result.
Therefore it but is not all to be the needed answer of user that these Search engines may be found out thousands of results, and many people had such experience, and they have spent a large amount of time and have inquired about in a Search engine, but do not find needed information at last; Yet the information that can not find out in a Search engine but might find in another Search engine, so they must go to the website of another Search engine to inquire about again; Because the neither one Search engine can be contained all station datas, so in several different Search engines, inquire about simultaneously and can obtain result preferably certainly, therefore, whenever in certain Search engine, can not find the information that needs, just can utilize each Search engine to retrieve continually, hope can be found needed result, but has wasted a large amount of time like this, feels inconvenience very again.
General internet Search engine (as Yahoo etc.) all is to adopt a kind of being called " spider " technology (Spider) to be implemented in information search on the internet; Its main operation principles is the webpage that comprises a plurality of other website hyperlink (Hyperlink) from, with each hyperlink in the webpage as a new starting point, remove to read the webpage at these hyperlink places, hyperlink from these new webpages that read again, remove to read other new wire side, circulation successively, so the webpage that is read will be more and more many, again the universal resource locator (url) address of each webpage of being read is write down, and the individual character in this webpage of index, then its index content being deposited in the URL address can be in the large database of inquiring about; When the user when this Search engine is sent query requests, it just is sent to the key word of user input in its database and inquires about, the individual character in the webpage that this key word is indexed with it compares, and returns the result of coupling then; Its database because the Query Result that it can return places one's entire reliance upon, so it need constantly remove the webpage of retrieving novel, could constantly expand its database, therefore, this class Search engine all is equipped with many large servers (Server) usually, on internet, search for new webpage around the clock, and accept user's inquiry simultaneously; This method is not only to the having relatively high expectations of hardware, and cost is also bigger, and general user oneself can't realize.
Summary of the invention
The objective of the invention is to realize a kind of method of on network, controlling automatically, inquiring about in the specified one or more Search engines of user in regular turn by system, the user need not enter respectively in each Search engine and inquire about, only need once configure querying condition, just can obtain the result that a plurality of Search engines are responded.
To achieve these goals, a kind of method of carrying out a plurality of Search engine retrievals in network simultaneously that is provided comprises the following step:
A. select the website of one or more Search engines;
B. via the more than one at least key word of input block input;
C. set the content of described each Search engine option;
D. according to the website of each Search engine of selecting, with the query argument of user's setting or the option content of Search engine, convert the interrogate format of the Search engine that can Gong be selected to, set up query argument and interrogate format characteristic of correspondence form shfft with each Search engine website;
E. transmit query argument in this feature form shfft to each corresponding Search engine;
F. receive the result for retrieval that each Search engine returns; And
G. show the result for retrieval that each returns from described each Search engine via an output unit.
Adopt method of the present invention can save user's activity duration, and simplify work flow; Because respond the result of inquiry, have not only more widely that information contains face, and the result of retrieval is more reliable from a plurality of Search engines.

H. the site information of returning is stored in a storage device 43, becomes a unified concordance list (inventory),, cause the user to be easier to find the content of wanting for user inquiring;
I. judge whether that all Search engines have all returned result for retrieval,, then skip to step k, otherwise continue next step if all Search engines have all returned result for retrieval;
J. move to next Search engine and be set as present Search engine, skip back to step c;
K. on output unit 45, show the result for retrieval in the concordance list; And
L. finish retrieval agent device (program module).
According to aforesaid operating process, further specify the function and the content of each operating process below:
At first, the invention provides a kind of use picture as shown in Figure 7 of user, the position input key word on query contents hurdle that can be therein is as computer magazine, promptly as described in the step a, the user selects some Search engines and imports key word or set search condition in case of necessity.
Secondly, as described in step c, the retrieval agent device is according to the impose a condition part of the interrogate format of obtaining Search engine of user, and it is described as follows.
Because the query requests with the user of each Search engine is sent to database when inquiring about, the interrogate format that oneself is all arranged, generally include the parameter such as key word, the logical relation between several key word, the number of results of at every turn returning, range of search of inquiry, and Search engine is to control the result that it returns by these parameters.Employed form when making each different Search engine under the different set condition, all can accept user inquiring, each Search engine employed interrogate format under different parameters is set is designed to a feature form shfft (Feature Table), its flow process comprises the following steps: as shown in Figure 8
C1. open a browser;
C2. enter the website of this Search engine;
C3. in the website of this Search engine, import key word;
C4. in the website of this Search engine, set each query argument of this Search engine;
C5. carry out the query actions of this Search engine;
C6. obtain the interrogate format and the query argument that are present in the search result that this Search engine returns;
C7. set up a feature form shfft; And
The content of c8. replacing this key word and each this Search engine option is corresponding query argument in this feature form shfft.
And the data structure of this feature form shfft is as follows, has generally comprised:
(1) Search engine title is as Yahoo;
(2) Search engine is accepted the network address form inquired about for the first time, as
http：//search.yahoo.com/search？p＝％s&d＝y&za＝and?&h＝s&g＝o&n＝％d；
(3) after Search engine is accepted inquiry for the first time, the network address form when same key word is inquired about next time, as
Http:// search.yahoo.com/bin/search? p=%s﹠amp; H=s﹠amp; N=%d; And wherein, the %s in the network address form, symbols such as %d are some query arguments;
(4) other sums up number of results that inspection (checksum) returns etc. for information about at every turn as Search engine
Among aforesaid example,, be not only to be defined in this kind URL form though alleged network address form is to be example with existing URL form.
Behind the interrogate format of having understood each Search engine, retrieval agent software of the present invention just can utilize these parameters, directly replaces the user to search in the database of different search engines; The user equally can be as in Search engine, these parameters are set, meeting of the present invention is found the interrogate format corresponding with Search engine according to these parameters in the feature form shfft, automatically these parameters are changed into the receptible form of Search engine then.For example, in the URL of last routine Yahoo interrogate format, %s is key word, %d is for allowing Yahoo return what results, if it is computer that the user sets the key word of inquiry, once return 20 results, then just the parameter in the URL interrogate format replaced to user's setting, replaceable in this example one-tenth http://search.yahoo.com/bin/search? p=computer﹠amp; H=s﹠amp; N=20 Here it is the final receptible interrogate format of Yahoo; After obtaining the receptible form of Search engine institute, the present invention just is sent to query requests a plurality of search engines simultaneously.
As described in step f, the utilization parsing table is dynamically analyzed the result for retrieval that returns, also comprise the following steps, as shown in Figure 9:
(f1) read the parsing table of Search engine;
(f2) obtain in the parsing table grammatical markers (Syntax Tag) of information such as relevant website theme URL address, brief introduction;
(f3) in the file that Search engine returns, seek grammatical markers; And
(f4) filter site information corresponding in the backspace file.
The Query Result that Search engine is returned carries out the reason of grammatical analysis (parse), be because the result of present all Search engines inquiries, all be with HTML (Hyper Text Markup Language, Hypertext Markup Language) form of file returns, and the form of each Search engine backspace file also is different.Therefore to understand these forms earlier, and make corresponding parsing table (Parsing Table), could carry out dynamic grammatical analysis the html format that Search engine returns at this Search engine.And generally include in the parsing table of each Search engine in the Search engine backspace file and the corresponding grammatical markers of information (Syntax Tag) such as website theme, URL address, website brief introduction.
According to the file of passing back being analyzed with the corresponding parsing table of Search engine, seek these grammatical markers hereof, could incite somebody to action the theme in each station data wherein, the URL address, finish messages such as website brief introduction come out; And the information that other is useless, fall as filtrations (Filter) such as the picture that comprised in the file and advertisements.
For example in the parsing table of Yahoo, following grammatical markers is arranged:
<li><A?HREF＝URL>TITLE</a>SUMMARY
After Search engine Yahoo returns search result, according to this parsing table to passing file analysis back, seek these grammatical markers hereof, when finding "＜li〉＜A HREF=" hereof, the file content that follow its back, until find〉till, be exactly the URL address of website.By〉to＜/a between file content be the theme of website.And＜/a〉afterwards file content is the brief introduction of website.So just the information analysis of website is come out in the destination file that can pass Search engine Yahoo back.
When carrying out aforesaid step h, because different Search engines may return identical station data, and the site address passed back of Search engine has not existed in fact sometimes.In order to improve the reliability of Search Results, each station data that the retrieval agent device is passed back Search engine is all checked.When the user searched at every turn, the retrieval agent device can all store each URL network address of finding in the concordance list, when analyzing a new URL website, just removed to check concordance list.If this URL exists, then represent the website of this URL, just it is deleted for repeating in concordance list; Otherwise, just its new adding in the concordance list.
And the flow process of this deletion repetition station data is as shown in figure 10, and it has comprised step:
H1 judges whether the URL address of newly obtaining has existed in the concordance list, then carries out step h2 if existed, does not then carry out step h3 if exist;
H2 deletes this URL address from search result, finish then.
The URL address that h3 will newly obtain adds in the concordance list, finishes then.
Except the site information that repeats is got rid of, the retrieval agent device also can replace the user to go to check whether each site address also exists.After each URL adress analysis came out, the retrieval agent device was just attempted removing to connect this website, does not exist if the information that website returns shows this URL address, just then the retrieval agent device is deleted this non-existent URL address in concordance list.For net result, show with unified inventory again, make the user be easier to find the content of wanting.
In sum, will be not difficult to find out that compare with traditional search method, method provided by the present invention not only can be saved user's time, and has simplified user's operating process widely.The user need not to inquire about one by one between each Search engine again, as long as once configure querying condition, just can obtain the result for retrieval of a plurality of Search engines simultaneously.And, because make in this way can be from many different Search engines result for retrieval, so information coverage rate is comparatively widely not only arranged, and Query Result is also more reliable.
Though describe concrete technical characterictic of the present invention in the above in detail, what should emphasize is that the preferred embodiment only is used for example explanation the present invention, is not to be used for limiting to scope of the present invention.Other is any not to break away from improvement or the change that spirit of the present invention is done, and all belongs to protection scope of the present invention.
