Embodiment Construction

[0029] figure 1 is a schematic structural diagram of an information recommendation device based on a decision tree according to an embodiment of the present invention. Such as figure 1 As shown, the decision tree-based information recommendation device disclosed in the present invention includes a user interface 1 , a decision tree generation module 2 , a weighting module 3 and a recommendation module 4 . Wherein, the user interface 1 obtains the user's information browsing record sequence based on the user's behavior, and transmits the information browsing record sequence to the decision tree generation module 2, wherein each information browsing record in the information browsing record sequence Includes the following: attributes associated with the browse target and browse time. The decision tree generation module 2 generates a decision tree based on the received information browsing record sequence, wherein each node in the decision tree represents the classification of ...

Abstract

The invention provides an information recommendation device and method based on a decision-making tree. The information recommendation device comprises a user interface, a decision-making tree generation module, a weighting module and a recommendation module, wherein the decision-making tree generation module can generate the decision-making tree based on a received information browsing record sequence, each node in the decision-making tree represents classes of attributes of different levels in the attributes related to a browsing target, and the root node of the decision-making tree represents a first-level class at the uppermost layer of the decision-making tree. The weighting module assigns weighted values to the node related to information browsing records based on the browsing time of each information browsing record in the information browsing record sequence after the decision-making tree is generated. The information recommendation device and method based on the decision-making tree can improve the efficiency and accuracy of information searching.

Description

technical field [0001] The present invention relates to an information recommendation device, and more particularly, to an information recommendation device and method based on a decision tree. Background technique [0002] At present, with the increasingly wide application of the network and the increasing variety of businesses in different fields, it is becoming more and more common for users to search and browse specific information (eg, search and browse products they intend to purchase) through the network. [0003] However, the existing information search and browsing systems and methods have the following problems: due to the rapid growth of the types and quantities of information, users need to spend a lot of time and energy to find interesting information in massive information data, so the efficiency of information search and Less accurate. [0004] Therefore, there is a need to provide an information recommendation device and method based on a decision tree that ...
