In a possible implementation manner, the body information of the clothing industry needs to be managed, so that a technician first establishes a corresponding body library according to the existing body information, for example, by inputting the existing body information in a server, and then the server automatically generates the corresponding body library according to the body information, and performs cloud sharing on the body library at a cloud.
In the management process, the user A needs to search a certain clothing body, for example, needs to search a skirt, so the user A firstly inputs information to be searched, for example, the user A inputs the 'skirt', and the service automatically analyzes the information to be searched and matches the information with the body library. In the embodiment of the invention, the ontology library comprises a multi-level ontology, for example, in the field of clothing, the first-layer ontology is clothing, the second-layer ontology is top-dress, bottom-dress, underwear, full-body dress, protective dress and the like, each ontology of the second layer further comprises other ontologies of the third layer, the server determines that matching ontology information exists in the ontology library according to 'skirt' input by the user a, in the embodiment of the invention, the matching ontology information comprises similar ontology information and/or top-layer ontology information and/or bottom-layer ontology information, the server optimizes the information to be searched according to the searched similar ontology information and/or top-layer ontology information and/or bottom-layer ontology information, so as to obtain optimized information to be searched, at the moment, corresponding search results are obtained according to the optimized information to be searched, and the search results are fed back to the user a, thereby obtaining a more accurate search result for the user.
Further, if the server does not match the matching body information corresponding to the information to be searched, the body library is optimized according to the information to be searched, and therefore the optimized body library is obtained.
In the embodiment of the invention, the body base is automatically matched with the information to be searched in each searching process of each user, so that the searching information of the user is optimized in a multi-level body information manner, the effective searching range of the user is greatly enlarged, and the searching accuracy of the user is improved; on the other hand, once unmatched ontology information is found, the ontology base is optimized from bottom to top immediately according to the information to be searched of the user, so that the ontology base is optimized and updated accurately in real time, and the management accuracy and the management efficiency of ontology resources are greatly improved.

s36) generating corresponding matching ontology information based on the selection operation.
In a possible implementation manner, the B user needs to search for information related to the suit, so as to input "suit" for searching, the server further obtains screening operation information of the user after obtaining the information to be searched, for example, by setting three options of "similar body", "upper body" and "lower body" on the user interface to prompt the user, for example, in an embodiment of the present invention, the B user clicks the "lower body" to further screen the body expansion operation of the "suit", after obtaining the "lower body" option selected by the B user, the server obtains matching lower body information corresponding to the "suit" according to a preset lower body screening operation, for example, the matching lower body information includes information of a collar, a sleeve, a pocket, a widget shape, an upper body front body, an upper body back body and the like, and at the moment, the server further obtains the selection operation of the user B on the matching lower-layer body information, for example, the user B selects a collar, sleeves and a pocket, and the server generates corresponding matching body information according to the collar, sleeves and pocket selected by the user B and the 'suit'.
It should be noted that the user may also select multiple pieces of screening information according to actual needs, for example, two screening options of a "similar body" and a "upper body" may be simultaneously selected, and at this time, the server obtains the body information corresponding to the information to be searched according to the two screening options, which also belongs to the protection scope of the present invention and is not described in detail herein.
In the embodiment of the invention, the searching operation of the user is subjected to multi-layer ontology searching and supplementing through the ontology library with a large amount of ontology information, so that the searching accuracy of the user in the searching process is greatly improved, and meanwhile, the user can further select the extended information provided by the server according to actual needs, so that the searching accuracy of the user is further improved, and the user experience is improved.
