社会新闻聚合中的社会信息处理

Social Information Processing in Social News Aggregation

Kristina Lerman

摘要:

博客、维基、Digg和Flickr等社交媒体网站的兴起突出表明,网络正在转变为一种参与性媒体,用户在其中协作创建、评估和分发信息。社交媒体引入的创新带来了一种与信息互动的新范式,我们称之为"社交信息处理"。在本文中,我们研究了社会新闻聚合器Digg如何利用社会信息处理来解决文档推荐和评级问题。首先,我们显示,随着时间的推移跟踪故事,社交网络在文档推荐中发挥着重要作用。本文的第二个贡献包括两个数学模型。第一个模型描述了如何从许多用户做出的独立决策中出现故事的协作评级和推广。第二个模型描述了用户的影响力、推广故事的数量和用户的社交网络如何随时间变化。我们发现模型的预测和从Digg收集的用户数据之间存在定性的一致性。

英文摘要:

The rise of the social media sites, such as blogs, wikis, Digg and Flickr among others, underscores the transformation of the Web to a participatory medium in which users are collaboratively creating, evaluating and distributing information. The innovations introduced by social media has lead to a new paradigm for interacting with information, what we call 'social information processing'. In this paper, we study how social news aggregator Digg exploits social information processing to solve the problems of document recommendation and rating. First, we show, by tracking stories over time, that social networks play an important role in document recommendation. The second contribution of this paper consists of two mathematical models. The first model describes how collaborative rating and promotion of stories emerges from the independent decisions made by many users. The second model describes how a user's influence, the number of promoted stories and the user's social network, changes in time. We find qualitative agreement between predictions of the model and user data gathered from Digg.
