Embodiment Construction

[0088] It should be pointed out that the following detailed description is exemplary and intended to provide further explanation to the present application. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

[0089] Specifically:

[0090] One is to improve the PageRank algorithm to evaluate the authority of system users.

[0091] The second is to establish a problem recommendation framework and recommendation process, so that the system can automatically recommend the problems to be solved to the most suitable users.

[0092] In order to achieve the above object, the technical solution adopted in the present invention specifically includes:

[0093]User Analysis Module: It is used to analyze the questions raised by users, extract characteristic content and analyze the authority of users in various fields.

[0094] Analysis and matching m...

Abstract

The invention discloses a problem recommendation method and system based on a PageRank algorithm. The method comprises the following steps that: on the basis of a traditional PageRank algorithm, carrying out improvement, and combining with semantic information including answer relevancy, answer quality, problem difficulty and the like to obtain the authority degree of a user in a community. A matching degree of a task and a participant is combined with a user degree of interest and user availability by aiming at innovative creativity and an innovative scheme released by the system to design a recommendation mechanism, and a proper problem is recommended to proper users. The users can carry out subjective and objective evaluation. The participator can obtain participation integrals, and the integrals can exchange a material reward and can be taken as a reference for enterprises to pick up talents. When the method is adopted, innovative design can be taken as an activity in which the public participate.

Description

technical field [0001] The invention relates to a question recommendation method and system based on PageRank algorithm. Background technique [0002] The rise of the Internet and cloud computing not only makes software developers encounter transformation problems, but also brings opportunities to social groups and individuals with good creative products, high-quality resources or technologies. Crowdfunding, crowd-wisdom, and crowd-creation have become the most effective H. Q&A community is a new form in the field of information retrieval. Users use natural language to initiate questions and answer behaviors. Compared with traditional information retrieval technologies (such as search engines), the Q&A community solves the following two problems: On the one hand, users change from using sporadic keywords as search conditions to using natural language questions with richer and clearer semantics This form, therefore, can express and describe its needs more clearly, and provi...
