Abstract	An online community involves many interactions among members. When the interactions are frequent and important enough, they are usually explicitly shown as "friend links " among community members. In this paper, a tag-based network evolution model is proposed to simulate the growth and evolution of social networks of online communities. Our model is an agent-based model in which community members are simulated as agents who can decide whether to link to other agents as friends or not, according to their tag similarity. A tag is a value that represents an agent's total trait. Agents' traits could be their interests, locations or ages. We demonstrate the emergent properties of online communities generated by our tag-based evolution model, and compare these properties with those of other three network evolution models: BA model, small world network and random network model. Furthermore, two real-world online communities are studied empirically and compared with the online communities evolved from our model. Experimental results show that our evolution mechanism can facilitate the formation of a higher-quality community in which distances between members are smaller and members are more closely clustered.
