微博转发预测算法评测系统的建立及性能比较

摘要

为解决微博转发行为预测问题,提出了一个基本的预测算法评测系统框架.该系统解决了原始微博数据的抓取和预处理,以及用户微博的转发和忽略行为的判定,微博和用户的特征提取等问题,为解决微博转发行为预测问题提供了技术基础.详细分析了现有文献和工作中的微博转发行为预测算法,阐述了它们的基本原理.通过定量实验分析了不同微博转发行为预测算法的在局部预测问题和全局预测问题方面的性能,并且从算法的原理等方面出发给出了定性的分析.%In order to solve the microblog retweeting prediction problem,firstly we constructed a basic prediction algorithm testing system which solves the origin data crawling and preprocessing problem.It also handles the feature retrieving and user social action judging problem.This system provides technical base for solving the microblog retweeting prediction problem.Secondly,we analyze the four representative algorithms of solving the target problem in detail.We conducted different experiments for quantitatively analyzing the algorithms' performance solving both the local prediction problem and the global prediction problem,respectively.
