Technical Field
The present application relates to search boxes, and in particular, to a method, an apparatus, a system, and a storage for recommending a vehicle type in a search box.
Background
Search is widely available in web pages and mobile application software as a main means for acquiring network information. As the domain is subdivided, it is slowly evolving by traditional search engines to personalized searches. The technical solutions used by different search service providers are different, and the display modes are also different. The present application takes a vehicle type search as an example for explanation.
Fig. 1 shows a schematic diagram of using a Baidu search for an audi brand, fig. 2 and 4 show pull-down menu options of home search boxes for easy car networks and cars, and fig. 3 and 5 show pull-down menu options of home search boxes for easy car searches and cars.
In the prior art, a search box is based on search keywords for maximum prefix matching, Google Suggest and AutoComplete technologies are mostly used, the real vehicle type search intention of a searcher is not accurately identified, and the efficiency of recommendation and advertisement delivery is not high.
FIG. 6 shows the front-end and back-end interaction steps in the Google Suggest's technical architecture as follows:
a user inputs vehicle type information, such as 'Cleisler' in a search box, a browser asynchronously sends a request to a Web server through AJAX, and meanwhile, the frequency of continuously inputting and submitting the request is controlled, and the request is submitted in a delayed mode;
after receiving the request, the server forwards the request to a memcached cache cluster, a compressed search tree (trie) is used for judging whether a prefix which can be matched exists in the cache or not, if so, a result is returned to the server, and the result is returned to the front end of the browser through AJAX by the server;
and if the cache does not have corresponding data, the data is obtained from the RDBMS and stored in memcached, and meanwhile, the data is returned to the front end of the browser through the server.
If the Autocomplete in the general search engine is used, the back end is relatively complex, but if the vehicle model information is only automatically supplemented, because the data volume is very small, the cache cluster is not needed at all, and the requirement can be met by using a memcached cache server or directly using an xml file.
In the prior art, the technologies used in a general search engine are not oriented to a specific field, the exclusive characteristics of the field are not strong, the particularity of vehicle type recommendation is not highlighted, and optimization is not carried out aiming at the vehicle type recommendation; at present, GoogleSuggest is applied without combining any searcher feature information, so that only one face of thousands of people can be achieved, but not the face of thousands of people can be achieved; in the prior art, vehicle type information input in a search box is only supplemented or only limited recommendation of similar vehicle types is made, and recommendation of various competitive product vehicle types and hot search vehicle types is lacked; in the prior art, the advertisement position attribute of a pull-down list box is not highlighted, and the presentation information is usually non-advertisement attribute information, not to mention the combination with accurate advertisements; in addition, in the prior art, vehicle type text information is contained in pull-down list boxes, and vivid media forms such as visual vehicle type diagrams and dynamic diagrams are lacked.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The invention utilizes the mature personalized recommendation algorithm to realize the personalization of the vehicle type recommendation of the search box, binds the behavior and the attribute of the searcher with the vehicle type to implement the recommendation, and helps the searcher to quickly find the target vehicle type matched with the search intention of the searcher, and the realization of the target effect is mainly to see the click rate improvement of the searcher on the pull-down menu option.
In order to achieve the purpose of the invention, the invention is mainly realized by three parts, namely user interest portrait preparation, a personalized recommendation/advertisement engine, a recommendation/advertisement triggering mechanism and the like.
FIG. 7 is a flow chart illustrating a process of preparing a user interest representation according to the present invention. The user interest portrait is obtained by analyzing the user log. The user interest portrait comprises a user long-term interest portrait generated according to behaviors such as historical access and clicking of a user and a user short-term interest portrait generated according to behaviors such as instant access and clicking of the user, the short-term interest portrait is often generated efficiently in a streaming mode, and the long-term interest portrait is often generated off-line every other day in a batch mode. When a user accesses a website or application software where a search box is located for the first time, the website can plant cookies at the browser end of the user, and the application software can record APP and open a log for the first time according to imei/idfa. The server generates an offline user log according to the browsing, accessing and purchasing behaviors of the user. The user center (comprising a user behavior library and a user attribute library) analyzes a user log by taking cookie and imei/idfa as units to form a multi-dimensional user interest portrait related to population attributes, historical behaviors, interest contents, preference tendency and vehicle purchasing stages of a user, wherein the most important user interest portrait is a vehicle type interest portrait and a vehicle purchasing stage portrait for the application, the vehicle type interest portrait comprehensively judges the interest weight of the user on a certain vehicle type according to behaviors of accessing, clicking, placing orders and the like of the user, and the vehicle purchasing stage portrait comprehensively judges which stage the user is in interest, intention, purchasing and purchased vehicles according to multi-channel source data comprising offline data. The vehicle purchasing stage drawing can help the system to accurately capture what kind of stage the user is in relative to the vehicle, so that different recommendation strategies are used for providing different vehicle type recommendations when recommending drop-down list box recommendations, for example, as many competitive vehicle types as possible are provided for the user to select in the interest stage, more accurate closing-up vehicle types of the same brand are provided for selection in the purchasing stage, and vehicle type changing recommendations are provided for the purchased vehicle user to select in the drop-down box. In addition, the access and clue data of all users are counted, and the vehicle type competition list and the hot vehicle searching type list are refreshed. The user behavior library comprises behaviors of data items such as user vehicle type channel browsing, clue submitting, praise, comment and collection, and the user attribute library comprises user gender, age range, academic history, marital status, work category, frequent residence, income level, interests and hobbies.
As shown in FIG. 7, the process of generating a representation of interest of a user includes:
and step 740, refreshing the hot vehicle searching type table.
Fig. 8 is a flow chart of personalized recommendations/advertisements provided by the present invention. Through user operations, such as drop-down list recommendation/advertisement space item exposure when a user puts a cursor in a search box and clicking actions of the user, a user interest portrait is pulled from the center of the user and a feature vector of the user is generated. When the drop-down list is expanded to execute recommendation, vehicle type interests do not need to be used as orientation conditions, for example, regional orientation recommendation is made to the whole users in a certain city, at this time, if only non-behavior features are used, namely user attribute features are used, a vehicle type behavior extraction and behavior feature conversion module is not needed, and the output of the module is the user feature vector. And converting the feature vector of the user into an initial recommended item list by using the feature vector of the user and a pre-stored feature-item correlation matrix. Preferably, the recommended item list can be preprocessed to filter out vehicle types with obvious problems, such as vehicle types with abnormal names, vehicle types with extremely low interest weight, and the like. And obtaining the vehicle type and the competitive product vehicle type with the correlation degree meeting the threshold value according to the long-term interest portrait of the user generated by the offline data, predicting the click through rate CTR according to the trained sequencing model, and selecting the first N as the final recommendation result to obtain the vehicle type interest portrait. The vehicle type interest portrait can be in the form of "(< vehicle type name, vehicle type quotation section > | < vehicle type name, vehicle type page URL, vehicle type quotation section > | < vehicle type name, advertisement type, advertisement material, advertisement landing page URL, vehicle type quotation section >)" and can be periodically brushed into an online cache.
As shown in fig. 8, the personalized recommendation/advertisement flow chart provided by the present invention includes:
at step 845, a final recommendation is formed.
FIG. 9 is a detailed flowchart of a method for accurately recommending vehicle types in a search box according to the present invention. When a user puts a focus (such as a cursor) in a search box but does not input information, a server firstly queries an online cache cluster, matching is carried out through compressing a Trie tree, and if a matching result exists, the matching result is directly displayed in a drop-down list box. If the online cache cluster is not queried, the online database can be called to continue matching, and if the matching result exists, the matching result is displayed in a drop-down list box. And if the matching result does not exist in the online database, matching is carried out in the user center, and if the matching result exists, the matching result is displayed in a drop-down list box. If the user center also does not have a match, the hot search type is presented in the drop-down list box. When the user inputs information in the search box, the contained vehicle type can be identified according to the input information, and the browser or the APP sends the vehicle type information to the server. The server calls the recommendation/advertisement list corresponding to the user, the real-time recommendation algorithm is utilized to jointly input vehicle types, long-term interest pictures of the user and content in a vehicle type competition list to be mixed, and the recommendation list aiming at the user is directly returned and displayed in a drop-down list box. Specifically, the logs are analyzed in a streaming manner according to the short-term behaviors and interest characteristics of the users through Kafka + storm real-time analysis.
In the returned search results, if the user hovers over the mouse in the drop-down list box and the corresponding option is an advertisement item, different types such as video advertisements, extensible advertisements, animation advertisements and the like can be triggered according to the advertisement type. If the user clicks the corresponding option in the pull-down list box to be the recommended item, the user jumps to the URL corresponding to the vehicle type page, and if the user clicks the corresponding option in the pull-down list box to be the advertisement item, the user jumps to the advertisement landing page.
As shown in fig. 9, the method for accurately recommending the vehicle type in the search box specifically includes:
Through the process, the recommendation result can be displayed to the user more accurately according to the interest portrait of the user.
