Embodiment Construction

[0022] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the interest of clarity and conciseness, not all features of an actual implementation are described in this specification. It should be understood, however, that in developing any such practical implementation, many implementation-specific decisions must be made in order to achieve the developer's specific goals, such as meeting those system- and business-related constraints and those Restrictions may vary from implementation to implementation. Moreover, it should also be understood that development work, while potentially complex and time-consuming, would at least be a routine undertaking for those skilled in the art having the benefit of this disclosure.

[0023] Here, it should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only the device structure and / or processing steps closely related ...

Abstract

The invention discloses an object classification method and an object classification device. The object classification method comprises the steps of converting a project sequence representing an object into a hierarchical structure corresponding to the object; comparing the similarity between the hierarchical structure corresponding to the object and the hierarchical structure of a known type; anddetermining the known type with the hierarchical structure thereof largest in similarity as the type of the object. Nodes in the hierarchical structure of the known type and / or the hierarchical structure corresponding to the object are generalized. Meanwhile,the deeper the level in the hierarchical structure, the larger the number of generalized nodes.

Description

technical field [0001] The present invention relates generally to the field of information processing. In particular, the present invention relates to a method and apparatus capable of accurately classifying objects. Background technique [0002] With the development of information technology, every aspect of people's life is inseparable from products and services based on information technology. In order to improve the satisfaction, friendliness, and convenience of users of products and services, users can be classified to provide corresponding products and services. For example, classify users into male and female, or classify users into sports enthusiasts, game and peripheral enthusiasts, etc. [0003] Taking a user of a shopping website as an example, the user's click sequence when browsing can reflect the user's preferences, concerns, and even gender. [0004] The traditional method adopts the method of manually defining and extracting features for sequence data. Ho...
