In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
The term "and/or" herein merely describes an associative relationship, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the term "at least one" herein means any one of a plurality or any combination of at least two of a plurality, for example, including at least one of A, B, C, and may mean including any one or more elements selected from the group consisting of A, B and C.
The retrieval system, the method and the device aim at overcoming the defect of low retrieval efficiency caused by the fact that when a plurality of retrieval systems are used for retrieval, the retrieval needs to be carried out on each retrieval system respectively, and then retrieval results are manually gathered and displayed.
As shown in fig. 1, the retrieval system includes an analysis presentation apparatus 101 and a plurality of retrieval systems, wherein the plurality of retrieval systems may be existing retrieval systems, for example, a human face and body information retrieval system 102, a vehicle information retrieval system 103, a wireless network retrieval system 104, and the like.
The analysis and presentation device 101 is configured to obtain a retrieval condition input by a user, or intelligently generate a retrieval condition according to a target to be retrieved input by the user, and send each sub-retrieval condition in the retrieval condition to a retrieval system corresponding to the sub-retrieval condition. The search condition includes a plurality of sub-search conditions, and the search condition may include, for example, 3 sub-search conditions: the face and body information of the object a, the vehicle information of the object a and the wireless network related information of the object a are queried, and at this time, the analysis and display device 101 sends each sub-retrieval condition to the face and body information retrieval system 102, the vehicle information retrieval system 103 and the wireless network retrieval system 104 respectively.
After receiving the sub-search condition, each search system searches according to the sub-search condition to obtain initial search result information, and sends the obtained initial search result information to the analysis display device 101.
The analysis and display device 101 receives initial retrieval result information fed back by the plurality of retrieval systems respectively, and generates and displays target retrieval result information.
Illustratively, when receiving the target to be retrieved, the analysis and presentation device 101 performs information feature extraction on the target to be retrieved to obtain the retrieval condition, where the retrieval condition includes a plurality of sub-retrieval conditions.
Exemplarily, if the target to be retrieved is an image to be retrieved, the analysis display device 101 performs object identification on the image to be retrieved after receiving the image to be retrieved, and determines a plurality of objects to be retrieved; and then, for each object to be retrieved, extracting image characteristic information corresponding to the object to be retrieved from the image to be retrieved, and generating sub-retrieval conditions corresponding to the object to be retrieved based on the extracted image characteristic information, so as to obtain the retrieval conditions for the plurality of objects to be retrieved.
After receiving the initial retrieval result information fed back by each retrieval system, the analysis and display device 101 integrates each initial retrieval information, and generates and displays target retrieval result information. Illustratively, firstly, according to a preset data display format, merging initial retrieval result information fed back by each sub-retrieval system to obtain target retrieval result information; and then, displaying the target retrieval result information.
In addition to the actual generated or existing search conditions described above, the analysis presentation apparatus 101 may also generate some pre-search conditions based on data stored in the respective search systems. And then, searching the pre-search conditions in each search system to obtain pre-search result information. The analysis and presentation device 101 stores the pre-search condition, the pre-search result information and the mapping relationship between the two in the storage device. In this way, before the analysis and presentation device 101 sends the sub-search condition to the search system corresponding to the sub-search condition, the sub-search condition matching the current sub-search condition is screened from the pre-search conditions stored in the storage device as the first target search condition; and under the condition that the first target retrieval condition is not screened, sending the current sub-retrieval condition to a corresponding retrieval system for retrieval, otherwise, acquiring pre-retrieval result information corresponding to the first target retrieval condition from a storage device. The processing mode can effectively improve the retrieval efficiency.
Further, after receiving the initial search result information fed back by each search system in response to each sub-search condition, the analysis display device 101 may further establish a mapping relationship between each sub-search condition and the corresponding initial search result information, and store each sub-search condition, the initial search result information corresponding to each sub-search condition, and the mapping relationship corresponding to each sub-search condition in the storage device.
In this way, before sending the sub-search condition to the search system corresponding to the sub-search condition, the analysis presentation device 101 first filters the sub-search condition matching the current sub-search condition from the sub-search conditions stored in the storage device as a second target search condition; and under the condition that the second target retrieval condition is not screened, sending the current sub-retrieval condition to a corresponding retrieval system for retrieval, otherwise, acquiring initial retrieval result information corresponding to the second target retrieval condition from a storage device. The processing mode can effectively improve the retrieval efficiency.
In addition, a mapping relation between the retrieval condition and the target retrieval result information can be established, and the retrieval condition, the target retrieval result information and the corresponding mapping relation are stored in the storage device.
As can be seen from the above description, the storage device may store the pre-search condition, the sub-search condition, and the search condition at the same time, so that after receiving the new search condition, the analysis display device 101 may first filter the search condition matching the current search condition from among the search conditions stored in the storage device as the third target search condition; and under the condition that the third target retrieval condition is not screened, respectively determining whether the storage device stores a first target retrieval condition or a second target retrieval condition which is matched with each sub-retrieval condition in the current retrieval condition, and if the first target retrieval condition does not exist and the second target retrieval condition does not exist, sending the corresponding sub-retrieval condition to the corresponding retrieval system for retrieval. And under the condition that the third target retrieval condition is screened, acquiring and displaying target retrieval result information corresponding to the third target retrieval condition from a storage device. Under the condition that the first target retrieval condition is screened, obtaining pre-retrieval result information corresponding to the first target retrieval condition from a storage device; and acquiring initial retrieval result information corresponding to the second target retrieval condition from a storage device under the condition that the second target retrieval condition is screened.
The following describes a search method, a search device, an electronic apparatus, and a storage medium according to the present disclosure with specific examples.
As shown in fig. 2, an embodiment of the present application discloses a retrieval method, which may be applied to the analysis display apparatus 101, and specifically includes the following steps:
s210, obtaining a retrieval condition, wherein the retrieval condition comprises a plurality of sub-retrieval conditions.
Here, after the user inputs the search condition through the client, the analysis presentation apparatus 101 that performs this step acquires the search condition input by the user.
The search condition may be a limitation condition of information to be searched by the user, for example, related information of the user whose query identity information is B may be vehicle information, face information, information of a used wireless network, and the like. It should be noted here that when the search method according to the embodiment of the present application is used to perform a joint search in a plurality of search systems, the search condition is not necessarily limited to the search for the user-related information, and may be a search for related information of an object having a certain characteristic, for example, a search for related information of a book whose sales volume is larger than a predetermined sales volume in a plurality of search systems.
In addition to the retrieval condition which is directly input by the user and comprises a plurality of retrieval sub-conditions, the user can also input a target to be retrieved, and then the retrieval condition is obtained by extracting the information characteristics of the target to be retrieved, wherein the retrieval condition comprises a plurality of sub-retrieval conditions. Through the target to be retrieved, a plurality of sub-retrieval conditions can be generated intelligently, so that the retrieval intelligence is improved, and the retrieval efficiency is improved.
For example, the target to be retrieved may be an image to be retrieved, and then the retrieval condition may be intelligently generated by the following steps:
firstly, carrying out object identification on the image to be retrieved, and determining a plurality of objects to be retrieved; and for each object to be retrieved, extracting image characteristic information corresponding to the object to be retrieved from the image to be retrieved, and generating sub-retrieval conditions corresponding to the object to be retrieved based on the extracted image characteristic information, so as to obtain the retrieval conditions for the plurality of objects to be retrieved.
A retrieval target image may include a plurality of retrieval targets, such as a person, a vehicle, and the like. Then, when the object to be retrieved is a person, based on the extracted image feature information, an age feature, a post feature, a face feature, a body feature, and the like of the object to be retrieved can be determined. When the object to be retrieved is a vehicle, the characteristics of the number plate, the vehicle type and the like of the object to be retrieved can be determined based on the extracted image characteristic information. Then, based on the determined age characteristic, post characteristic, face characteristic, human body characteristic, license plate number, vehicle type, etc., corresponding sub-search conditions can be generated respectively. The generated plurality of sub-search conditions constitute the search condition.
The sub-retrieval condition aiming at each object to be retrieved can be accurately generated based on the extracted image characteristic information, and the generated sub-retrieval condition is favorable for generating the accurate retrieval condition.
For example, the target to be retrieved may be a text to be retrieved, and then the retrieval condition may be intelligently generated by the following steps:
firstly, performing word segmentation processing on the text to be retrieved, and determining a plurality of target keywords based on words obtained by the word segmentation processing; and determining a plurality of sub-retrieval conditions based on the target keywords, so as to obtain the retrieval conditions for the text to be retrieved.
For example, the determined target keywords may be directly used as the sub-search condition, or the target keywords may be combined to generate the sub-search condition. For example, the text to be retrieved is "number plate and face feature of the query user C", and the target keyword corresponding to the text to be retrieved includes "user C", "number plate" and face feature ", then the sub-retrieval condition may be: license plate number of user C, face characteristics of user C.
The sub-retrieval conditions can be more accurate based on the extracted keywords.
And S220, respectively sending each sub-search condition in the search conditions to a search system corresponding to the sub-search condition.
After the retrieval conditions are acquired, the retrieval conditions need to be analyzed to determine retrieval systems corresponding to the respective sub-retrieval conditions, where the retrieval systems corresponding to the sub-retrieval conditions refer to retrieval systems storing data corresponding to the sub-retrieval conditions, for example, a person face and human body information retrieval system, a vehicle information retrieval system, and a wireless network retrieval system are used as corresponding retrieval systems when vehicle information, person face information, and wireless network information of a certain user are queried, as shown in fig. 3.
As shown in fig. 3, the parsing of the search condition may be performed by a data analysis engine, and the determining of the search system corresponding to the sub-search condition and the distributing of the sub-search condition may be specifically performed by a data aggregation engine in the analysis presentation apparatus 101.
And S230, respectively receiving initial retrieval result information fed back by each retrieval system in response to the sub-retrieval conditions.
After receiving the sub-search condition, each search system searches according to the received sub-search condition to obtain initial search result information, and feeds back the initial search result information to the analysis display device 101 executing the embodiment, and specifically, may feed back the initial search result information to the data aggregation engine in fig. 3.
Illustratively, the face and the face retrieval result information fed back by the human body information retrieval system can be received, and the vehicle retrieval result information such as the vehicle number and the vehicle type fed back by the vehicle retrieval system can be received. The received information is the initial search result information.
And S240, generating and displaying target retrieval result information based on the initial retrieval result information fed back by the plurality of retrieval systems respectively.
The data collection engine can send the received initial retrieval result information to the data analysis engine, and the data analysis engine analyzes and integrates the received initial retrieval result information after receiving each piece of initial retrieval result information to generate and display target retrieval result information. During information integration, the initial retrieval result information fed back by each retrieval system may be integrated according to a preset data display format, for example, the initial retrieval result information fed back by each retrieval system is put into a table with a preset format according to a preset sequence for display, and the data in each cell is displayed according to the preset data format of the cell. The initial retrieval result information fed back by each retrieval system is integrated, so that the data display effect can be improved, and the user can conveniently check the initial retrieval result information. After the target search result information is generated, the target search result information may be displayed at the display front end of the analysis display apparatus 101.
The sub-retrieval conditions are automatically distributed to the corresponding retrieval systems, the initial retrieval result information fed back by each retrieval system is processed, the target retrieval result information is generated and displayed, and the retrieval efficiency when the associated retrieval is carried out in a plurality of retrieval systems is effectively improved.
The search is performed based on the search condition that has already appeared, and in order to improve the search efficiency, the search condition that is likely to appear may be predicted from the data types stored in the respective search systems, and the search result may be determined based on the predicted search condition and stored. In this way, when a search condition or sub-search condition matching the predicted search condition appears, the corresponding search result can be returned directly.
Specifically, at least one data type common to a plurality of retrieval systems may be determined to obtain at least one target data type; the plurality of retrieval systems respectively store data of a plurality of data types, for example, each retrieval system stores data types such as user identification information, user face identification information, user mobile phone number and the like.
Then, determining at least one value of the at least one target data type to obtain at least one pre-retrieval condition, respectively sending the pre-retrieval condition to each retrieval system, and respectively receiving pre-retrieval result information fed back by each retrieval system in response to the pre-retrieval condition; for example, if the value D of the id information is used as a pre-search condition, the information of the object whose id information is D is searched during the search. Each retrieval system feeds back relevant information of the object D, for example, license plate number, vehicle type, face feature information, and the like of the object D, and specifically, the retrieval system may feed back the license plate number and the vehicle type of the object D in a plurality of retrieval systems, and the retrieval system feeds back the face feature information of the object D.
And finally, storing the pre-retrieval result information and the pre-retrieval conditions into a storage device. Here, the pre-search result information, the pre-search condition, and the mapping relationship between the two are stored in the storage device. For example, the object D is stored in correspondence with the license plate number and the vehicle type of the object D, and information such as the identification information, the face identification information, and the mobile phone number of the object D, so that pre-retrieval result information retrieved from different retrieval systems is associated.
The pre-retrieval condition is generated based on the values under the common data type in the plurality of retrieval systems, pre-retrieval is carried out by utilizing the pre-retrieval condition, and the pre-retrieval result information and the corresponding pre-retrieval condition are stored in the storage device, so that the corresponding pre-retrieval result information or the target retrieval result information can be directly obtained when the sub-retrieval condition or the retrieval condition matched with the pre-retrieval condition occurs, and the retrieval efficiency is improved.
Specifically, when a new sub-search condition is acquired, firstly, the pre-search condition matched with the new sub-search condition is screened from the pre-search conditions stored in the storage device as a first target search condition; and if the first target retrieval condition is not screened, sending the sub-retrieval condition to a retrieval system corresponding to the sub-retrieval condition for retrieval. And if the first target retrieval condition is screened, obtaining pre-retrieval result information corresponding to the first target retrieval condition.
When the sub-retrieval condition appears, firstly, whether the pre-retrieval condition matched with the sub-retrieval condition is stored or not is searched from the storage device, if yes, the corresponding pre-retrieval result information is directly obtained, otherwise, the sub-retrieval condition is sent to the corresponding retrieval system for real-time retrieval, and the retrieval efficiency is favorably improved.
As shown in fig. 3, the above-described process of determining the data type common to the respective retrieval systems and determining the pre-retrieval result information based thereon may be performed by a data aggregation engine. The process from determining the data type common to the retrieval systems to determining the pre-retrieval result information can be repeatedly executed according to a preset time interval along with the time and the updating and the change of the data, and the latest and most accurate pre-retrieval result information and the corresponding pre-retrieval conditions are ensured to be stored.
In some embodiments, after initial retrieval result information fed back by each retrieval system in response to the sub-retrieval condition is received, a mapping relation between the sub-retrieval condition and the initial retrieval result information may be established for each sub-retrieval condition, and the sub-retrieval condition, the initial retrieval result information, and the mapping relation may be stored in a storage device. The storage device may be a storage device in the analysis presentation device 101 that executes the search method, or may be a storage device independent of the analysis presentation device 101. For example, the sub-search condition, the initial search result information, and the mapping relationship between the two may be stored in a data storage engine executing the analysis presentation apparatus 101.
The sub-retrieval conditions and the initial retrieval result information are correspondingly stored in the storage device, so that the corresponding initial retrieval result information can be directly obtained when the same sub-retrieval conditions appear in the follow-up process, and the retrieval efficiency is improved. Specifically, after the sub-retrieval conditions are obtained, the sub-retrieval conditions matched with the currently obtained sub-retrieval conditions may be searched in the sub-retrieval conditions stored in the storage device, and the screened sub-retrieval conditions successfully matched are used as second target retrieval conditions; if the second target retrieval condition is not found, sending the sub retrieval condition to a retrieval system corresponding to the sub retrieval condition for retrieval; and if the second target retrieval condition is found, directly acquiring an initial retrieval result information corresponding to the second target retrieval condition from a storage device.
The second target search condition matching the currently acquired sub-search condition may include a second target search condition that is the same as the currently acquired sub-search condition, for example, the currently acquired sub-search condition and the second target search condition are both "item feather era", and the second target search condition matching the currently acquired sub-search condition is a second target search condition that is substantially the same as the currently acquired sub-search condition, for example, the currently acquired sub-search condition is "item feather era", and the second target search condition is "xichuba biography".
When a new sub-retrieval condition is obtained, whether the sub-retrieval condition is stored or not or a second target retrieval condition matched with the sub-retrieval condition is searched from the storage device, if the corresponding initial retrieval result information is directly obtained, the sub-retrieval condition is sent to a corresponding retrieval system for real-time retrieval, and therefore the retrieval efficiency is improved.
As time goes on, new data continuously appears, old data may also appear to be updated, so that data in each retrieval system continuously changes, and in order to ensure that initial retrieval result information obtained from the storage device is up-to-date, each sub-retrieval condition may be repeatedly sent to the retrieval system corresponding to the sub-retrieval condition according to a preset time interval; and respectively updating the initial retrieval result information corresponding to each sub-retrieval condition based on the new initial retrieval result information fed back by each retrieval system.
