Abstract: The present disclosure provides example methods and apparatuses of labeling product identifiers and methods of navigating products. Description information of one or more products is extracted. The description information of the products is clustered into a text. A subject analysis is applied to the text by using a text analysis method based on subject models to obtain one or more subjects and definition names for the subjects. A subject that is correlated to the description information of the product is used as an identifier of the product to label the product. The present techniques label the products with identifiers that have one or more user dimension attributes so that users may easily and intuitively find their desired products.

Abstract: The present disclosure provides techniques for commodity property navigation. These techniques may determine, by a computing device, current corresponding property information of any product node in a product information database, and corresponding property information of each commodity under the product node. The computing device may add the property information to be updated into the current corresponding property information of the product node when property information to be updated exists. The computing device may then perform commodity property navigation by using the updated current corresponding property information of the product node. Using techniques of the present disclosure, mining and navigation of novel commodity properties may be implemented automatically, therefore solving problems (e.g., failure for timely updating commodity properties) associated with existing techniques.
