Description

Search method and device

This case is about the field of network technology, especially about a search method and device.

With the rapid development of computer technology and network technology, and the improvement of the domestic Internet environment in recent years, the Internet has gradually become an important channel for obtaining information, and online information has also experienced explosive growth. The emergence of search technology provides a convenient means for Internet users to quickly find the information they need. The traditional search method mainly uses three types of search engines, namely, robot search engine (Robot), directory search engine (Directory or Catalog) and Meta Search Engine (Meta). The traditional search method mainly uses keyword matching to realize the retrieval of information. Because it is difficult for users to simply use keywords or keyword strings to faithfully express the content that really needs to be retrieved, the difficulty of expression leads to difficulty in searching, and the natural language The change of time, region or domain, the same concept can be expressed in different language expressions. For the same concept retrieval, different users may use different keyword queries, resulting in a large amount of irrelevant information returning to the user.

In order to solve the above problems, a smart search engine based on the smart search method has appeared in the industry. The knowledge base-based semantic analysis technology is used, and word-of-word technology, phrase recognition, and synonym are used to search for user input according to features. The parameters are analyzed to produce different search scenarios, ie search plans. The search parameter input by the user may be a vocabulary with certain characteristics, and may be a transliteration word or a homophone. If the user enters the wrong search parameter, for example, the user mistakenly inputs "Nokia" into "Nuo Ke Ya", the system platform can analyze the wrong word and automatically recommend the "Nokia" search scheme, the search scheme is A search plan for the search parameters entered by the user. In addition, when the user is too colloquial to describe "I want to purchase a mobile phone", the user actually searches for "mobile phone", so the search engine can only keep the "mobile phone" as a search plan. The above two schemes for generating a search plan can be implemented in the search engine through a spelling correction module and a rewrite module, respectively. Among them, the spelling correction module can change the wrong input word into the correct input word; the rewriting module can input the word segmentation, find the center word, etc., and rewrite it into a word suitable for searching for the application.

In the prior art, a search program is usually generated by using a dynamic loading module. Specifically, in an existing open source service platform, such as an Apache server, a dynamic expansion module can be implemented by writing C code. Among them, the Apache server is a web server that responds to HTTP (Hyper Text Transfer Protocol) requests to respond to the most basic web services. When dynamically loading a module on an Apache server, you first need to fully understand the operating mechanism of the Apache server, or write a PHP (Hypertext Preprocessor) module to repackage the Apache interface with a PHP module. The PHP module is compiled and dynamically loaded into the Apache server to provide services. The above dynamic loading module adopts the design of the ordinary responsibility chain mode, and once the task of the module is completed, the application is immediately exited.

In the process of implementing the present case, the inventor found that at least the following problems exist in the prior art: because the design of the Apache server itself is too complicated, implementing the Apache dynamic module directly leads to high module cost and increased maintenance difficulty. In addition, there is no coordination between the modules, and the module cannot be uniformly controlled. When there is a conflicting Apache module, if you directly improve the programming requirements of the module, you need to modify the previous module when adding new modules. When the number of modules is large, the cost will be large, and the module will be reduced. Scalability; if you use PHP module extensions, it will increase the difficulty of dependency and maintenance.

This case provides a search method and device, which can acquire search terms more quickly and facilitate the management of the execution module.

Of course, implementing any of the products of the present invention does not necessarily require all of the advantages described above to be achieved at the same time.

The main idea of this case includes using an independent platform to uniformly control the generation of search terms, managing multiple execution modules in the same execution sequence according to a unified interface, and determining the processing search parameters according to the accuracy level of the output results of each execution module. The module is executed, and based on the determined execution result of the execution module, the search engine is used to search and obtain the search result. For example, when the system selects the spelling correction module and the rewriting module to process the search parameters at the same time, when the output of the spelling error correction module and the rewriting module meets the accuracy requirements of the execution sequence, the search plan is searched. The spelling correction module and the rewriting module can be used to obtain the execution result of the spelling correction module and the rewriting module, and the search result of the search engine for the execution result; if the spelling correction module and the rewriting module In conflict with each other, the execution module retained in the search plan is determined according to the accuracy level of the output of the spelling correction module and the rewriting module.

When the output result of the execution module meets the preset accuracy requirement, the execution module is executed to obtain the execution result of the execution module.

In addition, in order to facilitate the comparison of the accuracy of the output results of different execution modules, the system can set a uniform accuracy level for the output of each execution module.

The accuracy level is used to characterize the suitability of the execution module to process the search parameters.

In addition, the system can also set an accuracy requirement for the execution sequence, and by comparing the relationship between the accuracy requirement and the accuracy level of the output result of the execution module, determine whether the output result of each execution module corresponding to the execution sequence satisfies the requirement. . If the accuracy level of the output result of the execution module is greater than the accuracy requirement corresponding to the execution sequence, it is determined that the output result of the execution module satisfies the accuracy requirement corresponding to the execution sequence; otherwise, the output result of the execution module is not determined Meet the accuracy requirements of the execution sequence.

The technical solutions in the present invention will be clearly and completely described in the following with reference to the drawings in the present invention. It is obvious that the described embodiments are a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative efforts are within the scope of the present disclosure.

As shown in FIG. 1 , a flowchart of a search method in the first embodiment of the present invention includes the following steps:

Step 101: Acquire a search parameter input by the user end, and determine an execution sequence of processing the search parameter according to a pre-configured or search tag selected by the user end.

The search tag is a category of the search result corresponding to the search parameter input by the user, and may include categories such as “product”, “information”, “technology”, and “all”. The user can select the search tag according to the user's needs. When the user does not select the search tag, the system can use the pre-configured search tag, that is, the "all" search tag.

Different search tags correspond to different execution sequences, and the execution sequence is a package package of one or more execution modules preset by the system, and the execution module in the execution sequence may be a customized module. The system may define an execution sequence including a part of the execution module, and perform execution selection on the execution module through the execution sequence; or configure the execution sequence as a default execution module by default. Each execution sequence set by the system can perform different processing on the search parameters input by the user end, corresponding to different processing functions and accuracy requirements on the output results. The user terminal may select a search tag corresponding to the required processing function according to the user's needs, and input the search parameter to be processed, and the system and the search tag determine an execution sequence for processing the search parameter.

Step 102: sequentially execute an execution module corresponding to the execution sequence according to the execution sequence, obtain an output result of the execution module for the search parameter, and generate a search plan according to an accuracy level of the output result of the execution module.

The search plan may include an execution module that processes the search parameters, and may also execute a processing strategy of the module for the search parameters.

Specifically, a unified interface may be set for each execution module in the execution sequence, and a uniform accuracy level is set for the output result of each execution module through the interface. The system can determine whether the accuracy level of the output result of the execution module satisfies the first accuracy requirement, and if so, determine that the search module processes the search parameter, that is, the execution module is included in the search plan.

After determining that the accuracy level of the output result of the execution module satisfies the accuracy requirement, it may also be determined whether the execution modules satisfying the first accuracy requirement conflict with each other, and if they conflict with each other, the conflicting execution modes are The execution module with the highest accuracy level of the output result in the group processes the search parameter, that is, only the execution module with the highest accuracy level of the output result in the conflicting execution module is retained in the search plan.

The determining whether the execution modules satisfying the accuracy requirement conflict with each other may include: determining whether there are at least two execution modules included in the predefined conflict sequence in the execution module that meets the first accuracy requirement; If yes, it is determined that the execution modules satisfying the first accuracy requirement conflict with each other; if not, it is determined that the execution modules satisfying the first accuracy requirement do not conflict with each other.

The output result of the execution module may further include an execution result of the execution module. When the output result of the execution module meets the second accuracy requirement and the search parameter meets a preset complexity requirement, the execution module is followed. The results of the execution are searched to obtain search results. The second accuracy requirement above is higher than the first accuracy requirement.

The execution result of the execution module on the search parameter may be a search parameter corrected by the execution module. For example, when the execution module is a spelling correction module and the search parameter is “Nuo Ke Ya”, the execution result of the spelling correction module is the corrected search parameter, ie “Nokia”; when the execution module is rewritten When the module and the search parameter are "I want to purchase a mobile phone", the execution result of the rewrite module is the corrected search parameter, that is, "mobile phone". When the output result of the execution module includes the execution result of the execution module, after obtaining the output result of the search parameter by the execution module, the execution result in the output result of the execution module may be notified to the execution sequence. The subsequent execution module causes the subsequent execution module to generate an output result according to the execution result of the execution module.

Step 103: The search module determined by the search plan processes the search parameter, obtains the execution result of the determined execution module, and performs a search according to the execution result to obtain the search result.

Specifically, each execution module in the search plan may separately process the search parameters, obtain the execution result of each execution module, and determine whether the number of execution results is greater than the specified output number; if the number of execution results is greater than The designated output number is sent to the search engine as the search term, and the search result is obtained by the search engine.

In addition, while the execution result of the execution module is sent to the search engine for searching, the system may also return the execution result of the execution module to the client for use by the user. The system can also return the execution result of the execution module to the client only, and no longer send it to the search engine to reduce the pressure on the search engine. For example, when the execution module is a filter module for the prohibited word, the execution result can be directly returned to the client without searching according to the execution result.

The present invention includes the following advantages: coordinate the execution modules that may conflict according to the accuracy of the execution result of the execution module, and can obtain the user intention behind the search parameters more quickly and accurately and convert the user intention into a machine language that the search engine can understand. And the execution strategy facilitates the management of the execution module, and can output better search terms without changing the original execution module. In addition, the execution of the module is independent, does not affect the stability of the search engine core query service, and the execution module can be distributed, not bound to the search engine service, or compete with the search engine for server resources. The pressure generated on the server is small and the processing speed is fast. Of course, implementing any of the products of the present invention does not necessarily require all of the advantages described above to be achieved at the same time.

The search method in the present case can be applied to the system architecture shown in FIG. 2, the system includes a client, a parameter processing server, and a search engine server, wherein the client is used to send a search request to the parameter processing server. Enter a search parameter and select a search tag preset by the parameter processing server; the parameter processing server invokes an execution module corresponding to the execution sequence according to an execution sequence selected by the user terminal, and obtains an output result of the execution module on the search parameter, when the execution mode is performed When the output result of the group satisfies the accuracy requirement corresponding to the execution sequence, the execution result of the execution module is sent to the search engine server and the client; the search engine server uses the execution result from the parameter processing server as a search term, Search for words to search for results.

Specifically, the parameter processing server includes an error correction module, a rewriting module, and other execution modules, and each of the execution modules may separately process the search parameters to obtain an output result respectively, and when the output result satisfies the execution sequence corresponding When the accuracy is required, the execution result of the execution module can be returned to the client as a search term and sent to the search engine server. The search engine server includes an analysis module, a query module, and a merge module, wherein the parsing module is configured to parse the execution result from the parameter processing server to obtain a search term; the query module is configured to query the website according to the search term. The database, such as the web crawler structure, obtains the query result; the merge module is used to merge the query results of the query module to obtain the search result.

It should be noted that, in the specific implementation manner of the present invention, the parameter processing server and the search engine server in the system architecture may be separately deployed, or the parameter processing server and the search engine server may be merged into the same system. a device. The above parameters processing server and search engine server deployment methods do not affect the scope of protection of this case.

The search method in this case is described in detail below in combination with the above application scenarios.

As shown in FIG. 3, a flow chart of a search method in the second embodiment of the present invention includes the following steps:

Step 301: The parameter processing server acquires the search parameter input by the user end, and determines an execution sequence of processing the search parameter according to the pre-configured or search tag selected by the user end.

Step 302: The parameter processing server sequentially calls the execution module corresponding to the execution sequence according to the execution sequence, and obtains an output result of the execution module to the search parameter.

Step 303: The parameter processing server determines whether the accuracy level of the output result of the execution module satisfies the first accuracy requirement.

If the result of the determination is yes, then step 304 is performed; otherwise, the process ends.

Step 304: The parameter processing server determines whether the execution modules satisfying the first accuracy requirement conflict with each other.

If the execution modules that meet the first accuracy requirement conflict with each other, the module 305 is executed; otherwise, step 306 is performed.

Step 305: The parameter processing server determines that the execution module is processed by the execution module with the highest accuracy level of the output result in the conflicting execution module, and the execution module is retained in the search plan to obtain the execution result of the execution module.

Step 306: The parameter processing server processes the search parameter by using the execution module determined by the search plan, and obtains the execution result of the determined execution module.

Step 307: The parameter processing server determines whether the number of execution results of the execution module is greater than a specified number of outputs.

If the number of execution results is greater than the specified number of outputs, step 308 is performed; otherwise, step 309 is performed.

Step 308: The parameter processing server sends the execution result with the highest accuracy level in the execution result of the execution module as a search term to the search engine server, and returns the execution result to the client.

It should be noted that after performing this step, step 310 can be continued.

In step 309, the parameter processing server sends all execution results as search words to the search engine server, and returns the execution result to the client.

Specifically, a unified interface may be set for each execution module in the execution sequence, and a uniform accuracy level is set for the execution result of each execution module through the interface. When the number of retained execution results is greater than the specified number of outputs, the execution results are sorted according to the accuracy level, and the execution result with the specified number of precision levels is selected as the search plan.

In the specific implementation process, there are multiple possibilities due to the output of the execution module in the system, that is, the matching of the input keywords and the like. If the entered keyword exactly matches the word in the module, the output accuracy of the module is high. Since the dictionary index of each module is independent, there is no correlation between the output precision of different modules. Since each module is independent of each other, it is not necessary to change the previous module when adding a new module, and a unified interface can be set for the module output for the module to set the accuracy of the output. Each module has different accuracy algorithms, and the results are not comparable. The output results are unified to several accuracy levels in the interface, which serves as a reference for unified selection at the time of output.

In step 310, the search engine server searches for the search term and obtains the search result.

It should be noted that the case can also be realized by independently setting up a service by each module, and the service can be integrated by the user terminal respectively calling their respective services. The technical solution proposed in this case can be implemented in C++, and running on a Linux system can achieve the best implementation effect.

The present invention includes the following advantages: coordinate the execution modules that may conflict according to the accuracy of the execution result of the execution module, and can obtain the user intention behind the search parameters more quickly and accurately and convert the user intention into a machine language that the search engine can understand. And the execution strategy facilitates the management of the execution module, and can output better search terms without changing the original execution module. In addition, the execution of the module is independent, does not affect the stability of the search engine core query service, and the execution module can be distributed, not bound to the search engine service, or compete with the search engine for server resources. The pressure generated on the server is small and the processing speed is fast. Of course, implementing any of the products of the present invention does not necessarily require all of the advantages described above to be achieved at the same time.
