自适应推荐模型中的异质性、质量和信誉
Heterogeneity, quality, and reputation in an adaptive recommendation model
摘要:
推荐系统帮助人们解决信息过载的问题。最近提出的自适应新闻推荐器模型[Medo等人,2009年]是基于在社交网络中的新闻传播。通过基于代理的模拟,我们研究了模型的“好的更丰富”的功能,并确定哪些属性是必要的用户在网络中发挥主导作用。我们进一步研究过滤效率的模型,以及其对恶意和垃圾邮件行为的鲁棒性。我们表明,将用户的声誉在推荐过程中可以大大提高结果。
英文摘要:
Recommender systems help people cope with the problem of information overload. A recently proposed adaptive news recommender model [Medo et al., 2009] is based on epidemic-like spreading of news in a social network. By means of agent-based simulations we study a "good get richer" feature of the model and determine which attributes are necessary for a user to play a leading role in the network. We further investigate the filtering efficiency of the model as well as its robustness against malicious and spamming behaviour. We show that incorporating user reputation in the recommendation process can substantially improve the outcome.
