摘要

作为一种新环境下的信息资源，微博产生的海量数据也具有相应的生命周期。以3个微博热门话题数据为分析对象，将评论数作为微博信息生命周期的表征量，分析微博信息生命周期的特征、分布类型、半衰期等。发现微博信息生命周期有负指数型、平缓型、爆发型和锯齿型4种类型，其类型特征与微博活跃度无关，并且微博信息不具有特定的半衰期。

关键词： 微博; 生命周期; 寿命; 半衰期; 评论数

Abstract

As a kind of information resource in new environment, the mass data produced by Microblog has its lifespan. Based on the study of three hot topics from Microblog, the amount of comments is considered as the characteristic parameter of Microblog message's lifecycle. The study analyzes the features and distribution of Microblog message's lifecycle and its half-life. The types of Microblog message's life cycle include negative exponent, flat, burst andzigzag. The Microblog doesn't have a fixed half-life and its activity is irrelevant to its lifespan type.

Key words： Microblog; life cycle; lifespan; half-life; comment count
