Description
Technical Field
The invention relates to the field of application program commodity configuration, in particular to a commodity duplicate removal method and system based on material combination.
Background
The micro tax platform is a unified platform for supporting the personalized configuration of application program commodities in the whole country and in each region. The enterprise service channel of the micro tax platform is an application program mall and stores application program commodities. The general online shopping malls display nationwide unified commodities, and the enterprise service channel can display not only nationwide promoted commodities but also locally configured commodities in the region where the user is located, so that the requirement of regional personalized configuration is met.
If a certain region does not want to promote a certain national commodity, or the price of a certain commodity in a certain region is different from that of other regions, or a certain commodity in a certain region wants to display another commodity name, etc., for these special requirements, a set of same commodities can be configured in the local region, and the attributes of "whether to promote", "commodity unit price", "commodity name", etc. are modified to realize the purpose. Since various commodity attributes including "commodity name" may vary, the conventional deduplication method is not applicable.
Disclosure of Invention
In order to solve the technical problem of difficulty in commodity de-duplication caused by changing commodity attributes in an application program market in the background art, the invention provides a commodity de-duplication method based on material combination.
The material is actually the minimum unit after the splitting of the commodity, and for the commodity with local personalized requirements, although attributes such as commodity unit price, commodity name and the like may be changed, the material combination corresponding to the commodity is usually not changed, so that the material combination becomes the best basis for the deduplication operation. For application program commodities, materials represent different application program functional modules, and different material combinations may correspond to a set of complete application programs or a part of functions in the application programs. The process of trying or purchasing the commodity is the process of trying or purchasing the material combination corresponding to the commodity.
The commodity de-weight method based on material combination comprises the following steps:
step 1, acquiring a complete list of national commodities, provincial commodities and municipal commodities corresponding to a current user, and sequencing the national commodities, the provincial commodities and the national commodities according to the sequence of the municipal commodities, the provincial commodities and the national commodities, wherein the commodities are modularized application programs;
step 2, acquiring corresponding relations between material combinations and a commodity number list, wherein initial values of 'commodity numbers after duplication elimination' of all the corresponding relations do not exist, the materials are functional modules of commodities, different material combinations form different application program commodities, the corresponding relations between the material combinations and the commodity number list are that the material combinations of all the commodities are collected and then classified, commodity numbers corresponding to the same material combinations are recorded in the same commodity number list, and the 'commodity numbers after duplication elimination' are marks indicating that the commodity number list contains the commodity numbers of the commodities which should be reserved;
step 3, splitting the obtained complete commodity list of the current merchant into a market-level commodity list, a provincial commodity list and a national commodity list, and setting the serial number of the commodity list as t, wherein the initial value of t is 1, and the serial numbers of the market commodity list, the provincial commodity list and the national commodity list are 1, 2 and 3 respectively from the initial value;
step 4, acquiring a list t of articles to be deduplicated;
step 5, obtaining commodities in a to-be-deduplicated commodity list t;
step 6, splitting the corresponding relation between the material combination and the commodity number list into a corresponding relation containing a commodity number after weight removal and a corresponding relation not containing a commodity list after weight removal, when the corresponding relation containing the commodity number of the commodity in the step 5 exists in the corresponding relation of the commodity number after weight removal, the commodity is skipped over, when a next commodity still exists in the commodity list t, the step 5 is skipped, when the next commodity does not exist in the commodity list t, the step 4 is skipped to by setting t to t +1, and when the commodity number list t is larger than 3, the step 8 is skipped to;
step 7, when the corresponding relation containing the commodity number of the commodity in the step 5 does not exist in the corresponding relation of the commodity number after the duplication removal, searching the corresponding relation containing the commodity in the corresponding relation without the commodity number after the duplication removal, updating the searched corresponding relation, completing the commodity number after the duplication removal, jumping to the step 5 when a next commodity still exists in the commodity list t, and jumping to the step 4 when the next commodity does not exist in the commodity list t by setting t to t +1, and jumping to the step 8 when the commodity list t is more than 3;
and 8, screening the complete list obtained in the step 1 according to all the processed 'commodity numbers after weight removal', reserving commodities with the commodity numbers still existing in the 'commodity numbers after weight removal', deleting other commodities, and obtaining a commodity weight removal list.
