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 invention.
For the convenience of understanding of the embodiments of the present invention, the following description will be further explained with reference to specific embodiments, which are not to be construed as limiting the embodiments of the present invention.
Fig. 1 is a schematic flow chart of a method for identifying a commodity according to an embodiment of the present invention, and as shown in fig. 1, the method specifically includes:
and S11, acquiring the categories, brands and at least one specification model parameter of the commodities to be identified.
In the embodiment of the invention, a plurality of commodities are obtained from the database of the online shopping mall, and the commodities are identified by using the commodity identification method provided by the embodiment of the invention so as to identify the same commodity. Hereinafter, for convenience of description, the plurality of commodities will be referred to as commodities to be identified.
Further, the commodity information of each commodity to be identified can be obtained from the database, and the commodity information includes but is not limited to: a category, a brand, and at least one specification model parameter.
Taking a certain mobile phone as an example, the categories refer to: first class, digital, second class, communication, third class, mobile phone; the brand refers to Hua Shi; the rule model parameters include, but are not limited to: 256G and 8G.
And S12, classifying the commodities to be identified.
As an embodiment, in step S12, the obtained multiple commodities to be identified are first classified according to categories and brands, so that commodities of the same category and brand are classified into the same category, and multiple categories are obtained.
And S13, aiming at each commodity to be identified in each category, determining a target commodity matching template matched with the commodity to be identified from a plurality of preset commodity matching templates corresponding to the categories on the basis of at least one specification model parameter of the commodity to be identified.
In step S13, the to-be-identified commodities in each category are further precisely identified, so as to identify the commodities of the same type.
As an embodiment, commodity matching templates corresponding to a plurality of commodities can be preset manually according to experience, each commodity matching template includes standard rule parameters of a commodity, which means that the commodity matching template can be used to describe a commodity.
For example, taking a commodity as a mobile phone as an example, the main classes in the matching template include: first class, digital, second class, communication, third class, mobile phone; brand name: huashi, millet or apple, etc.; the main attributes of the specification and the model are as follows: and commodity information such as internal memory, transportation or camera.
Based on the commodity matching template, at least one specification model parameter of the commodity to be identified and a standard specification model parameter in each commodity matching template can be matched for each commodity to be identified in each category, if the commodity to be identified is matched with the standard specification model parameter, the commodity to be identified belongs to the matched commodity matching template, and the commodity matching template successfully matched with the commodity to be identified is referred to as a target commodity matching template for convenience in description.
How to determine a target product matching template matching the product to be identified from a plurality of preset product matching templates corresponding to the category based on at least one specification model parameter of the product to be identified is exemplified by different embodiments hereinafter, and will not be described in detail here.
And S14, dividing the commodities to be identified into commodity sets corresponding to the target commodity matching templates.
As can be seen from the above description, if the to-be-identified product matches with the target product matching template, it means that the to-be-identified product belongs to the product described by the target product matching template, and therefore, all the to-be-identified products can be divided into sets corresponding to the target product matching templates corresponding thereto, so as to obtain a plurality of product sets. The commodities in the same commodity set are the same type of commodities. For example, one of the obtained sets of items includes a certain model of mobile phone of a brand. As another example, a certain collection of goods includes a certain model of notebook computer of millet brand.
The commodity identification method provided by the embodiment of the invention comprises the steps of obtaining the types, brands and at least one specification model parameter of a plurality of commodities to be identified; classifying a plurality of the commodities to be identified; for each commodity to be identified in each category, determining a target commodity matching template matched with the commodity to be identified from a plurality of preset commodity matching templates corresponding to the category based on at least one specification model parameter of the commodity to be identified; the commodities to be identified are divided into commodity sets corresponding to the target commodity matching templates, and the commodities and the commodity matching templates are matched through the scheme, so that the same type of commodities of all merchants can be accurately identified.
Fig. 2 is a flowchart of an embodiment of step S13 according to an embodiment of the present invention, and as shown in fig. 2, the method specifically includes:
s21, searching a plurality of commodity matching templates corresponding to the categories by taking the first specification model parameters of the commodities to be identified as keywords.
Generally, a certain type of commodity can be identified through a small number of key specification model parameters, and therefore, as an embodiment, when matching is performed, preset key specification model parameters (hereinafter referred to as first specification model parameters for convenience of description), first, matching of the commodity and a commodity matching template is performed through the first specification model parameters.
Specifically, as an optional implementation manner, the first specification model parameter is used as a keyword, and a plurality of commodity matching templates corresponding to the category where the commodity is located are searched from a plurality of preset commodity matching templates. And the first specification model parameters of the plurality of commodity matching templates corresponding to the category of the commodity are the same.
And S22, if the commodity matching template containing the keywords is found, determining the found commodity matching template as the target commodity matching template.
And if the commodity matching template with the same parameters as the first specification model is found from the plurality of commodity matching templates, determining the commodity matching template as a target commodity matching template. And the parameters of the first specification model are the same, so that the matching result is accurate.
Further, a matching degree (for example, 100%) is set for the to-be-identified product successfully matched with the target product matching template, the to-be-identified product and the product recorded by the target product matching template are considered to be the same product, and at this time, the matched multiple products are all products accurately matched.
And S23, if the commodity matching template containing the keyword is not found, determining the matching degree of the commodity to be identified and the plurality of commodity matching templates corresponding to the categories based on at least one specification model parameter of the commodity to be identified.
And S24, determining the commodity matching template with the matching degree exceeding a preset threshold value as the target commodity matching template.
Here, fuzzy matching is performed, because descriptions of the same commodity by each merchant may be different, there may be some commodities which cannot be accurately matched after the accurate matching, and in this case, fuzzy matching is continued
How this is achieved is illustrated below by means of two embodiments, fig. 3 and fig. 4, which are not described in detail here.
According to the commodity identification method provided by the embodiment of the invention, the specification and model parameter information of the commodities is firstly accurately matched, and then fuzzy matching is carried out, so that most commodities can be identified.
Fig. 3 is a flowchart of an embodiment of step S23 according to an embodiment of the present invention, and as shown in fig. 3, the method specifically includes:
s31, extracting the feature vector of the commodity to be identified according to at least one specification model parameter of the commodity to be identified.
In an optional embodiment of the present invention, since descriptions of the same product by each merchant may differ, there may be some products that cannot be accurately matched after the accurate matching, and the product needs to be identified according to the description of the product by the merchant. Through analysis of the commodity description information, a plurality of characteristics corresponding to the commodity are obtained from the description information of the commodity, and a characteristic vector of the commodity is calculated according to the obtained plurality of characteristics.
For example, the natural language recognition NLP algorithm is used to perform overall language semantic recognition and calculate feature vectors according to the information described in the product or the specification and model parameters described in the product page.
And S32, calculating the similarity between the characteristic vector and the standard characteristic vectors of the plurality of commodity matching templates corresponding to the categories.
And comparing the similarity of the feature vector of the to-be-identified commodity obtained by the calculation with the feature vectors of the plurality of commodity matching templates corresponding to the category of the commodity.
And S33, determining the matching degree of the to-be-identified commodities and the plurality of commodity matching templates corresponding to the categories based on the similarity.
And representing the matching degree of the commodity to be identified and the commodity matching template by using the similarity of the feature vector of the commodity to be identified and the feature vectors of the plurality of commodity matching templates corresponding to the category of the commodity.
And setting the commodity matching template with the similarity between the feature vector of the commodity to be identified and the feature vectors of the commodity matching templates corresponding to the category of the commodity exceeding a preset threshold value (for example, 95%) as a target commodity matching template, and further obtaining a plurality of commodities which are the same commodity as the target commodity matching template.
Fig. 4 is a flowchart of another embodiment of step S23 provided in the embodiment of the present invention, and as shown in fig. 4, the method specifically includes:
and S41, aiming at each commodity set, determining a standard commodity from the commodity set according to the matching degree of the to-be-identified commodity and the commodity matching template corresponding to the commodity set and the historical sales information of the to-be-identified commodity, and obtaining a plurality of standard commodities.
And in the commodity set which is matched with the target commodity matching template and identified as the same commodity, determining a standard commodity under the condition of the matching degree, the historical sales volume and the historical sales price of each commodity and the commodity matching template corresponding to the commodity set, and further obtaining a plurality of standard commodities of a plurality of commodity sets.
For example, the matching degree of a certain commodity and the commodity matching template corresponding to the commodity set where the commodity is located is 100%, the historical sales volume of the commodity is the highest compared with the rest of the commodities in the commodity set, the historical sales price is stable, and the difference between the historical sales volume of the commodity and the manufacturer guide price or the average sales price of the commodity on the market is within a set range, then the commodity is taken as the standard commodity.
S42, if the specification model parameters are found in the commodity matching template, determining a first matching degree of the specification model parameters and the commodity matching template based on a preset weight value corresponding to the specification model parameters.
If the corresponding specification and model parameters are found in the commodity matching template, taking a preset weight value (for example, 1) corresponding to the specification and model parameters as a first matching degree of the commodity and the commodity matching template.
Optionally, if the corresponding specification model parameter is found, the matching degree obtained by the specification model parameter is set to 0.
For example, the memory of a certain mobile phone is 256G, if a product matching template with the memory of 256G is found, the matching degree is recorded as 1, further, the shipping storage is 8G, if a product matching template with the shipping storage of 8G is found, the matching degree is recorded as 1, and then, the matching degree obtained by the mobile phone is 2.
And S43, determining the matching degree of the commodity to be recognized and the commodity matching template based on the first matching degree of each specification model parameter and the commodity matching template.
And obtaining the matching degree of the commodity to be identified and the commodity matching template according to the sum of the first matching degrees obtained by matching each specification model parameter and the commodity matching template, determining the commodity with the matching degree exceeding a set value (for example, 10) as the same commodity as the commodity matching template, and obtaining a commodity set corresponding to each commodity matching template.
It should be noted that the two flows shown in fig. 3 and fig. 4 are only two possible implementations of fuzzy matching, and in practical applications, other implementations may also exist. For example, the flow shown in fig. 3 is executed first, and then the flow shown in fig. 4 is executed for the commodity of the unmatched upper template, or the flow shown in fig. 4 is executed first, and then the flow shown in fig. 3 is executed for the commodity of the unmatched upper template, which can realize multi-layer matching.
Fig. 5 is a flowchart of a method for establishing a standard commodity library according to an embodiment of the present invention, and as shown in fig. 5, the method specifically includes:
and S51, if the commodity matching template containing the keywords is found, setting the matching degree corresponding to the commodity to be identified as a preset value.
If the commodity matching template containing the keywords is found, the matching degree of the to-be-identified commodity and the commodity matching template is set as a preset value (for example, 1).
For example, the memory of a certain mobile phone is 256G, the shipping number is 8G, if a matching template of the memory 256G and the shipping number 8G is found, the matching degree is recorded as 1, and then the matching degree obtained by the mobile phone is 1.
And S52, aiming at each commodity set, determining a standard commodity from the commodity set according to the matching degree of the to-be-identified commodity and the commodity matching template corresponding to the commodity set and the historical sales information of the to-be-identified commodity, and obtaining a plurality of standard commodities.
And S53, storing a plurality of standard commodities in a standard commodity library.
In the commodity set which is matched with the target commodity matching template and identified as the same commodity, determining a standard commodity under the condition of the matching degree, the historical sales volume and the historical sales price of each commodity and the commodity matching template corresponding to the commodity set, further obtaining a plurality of standard commodities of a plurality of commodity sets, storing the obtained plurality of standard commodities into a standard commodity library, and recording the incidence relation of the rest commodities in the commodity set and the standard commodities as the same commodity.
For example, the matching degree of a certain commodity and the commodity matching template corresponding to the commodity set in which the commodity is located is 100%, the historical sales volume of the commodity is the highest compared with the rest of the commodities in the commodity set, the historical sales price is stable, and the difference between the historical sales volume of the commodity and the manufacturer guide price or the average sales price of the commodity on the market is within a set range, so that the commodity is used as a standard commodity and is stored in a standard commodity library.
