Most of overlapping community detection algorithms cannot be applied to networks with highly overlapping community such as online social networks where individuals belong to many communities. One important reason is that many algorithms detect communities based on the explicit borders where nodes have more connections inside the communities, however, when the vertices' membership number gets large,...
Recently the disconnected Delay-Tolerant Network (DTN) draws more and more attention.It is different from the traditional Ad-hoc and MANET. In DTN the disconnected nature and lack of end to end connectivity between nodes mean that the nodes communicate by the way of store-carry-forward. Therefore, it was rencently been recognized that mobility can be turn into a useful ally, by making nodes carry...
As an important part of multimedia retrieval, researches on 3D model retrieval concentrate on the shape-based retrieval method. It is a promising way to improve retrieval performance by adopting semantic information. At present, semantics of an object is usually represented by several keywords. However, acquiring each 3D model's semantics is very difficult and expensive. To solve the problem, the...
One of the fundamental challenges for Peer to Peer (P2P) systems is the ability to manage risks involved in interacting and collaborating with prior unknown and potentially malicious parties. Reputation-based trust management systems have proven to be essential to enforcing cooperative behavior in P2P networks. However, in many existing reputation-based trust models, the validity of peers' trust valuation...
Personal absorptive capacity of knowledge is basic foundation for knowledge creation and transfer. The Community of Practice (CoP) is the engine of knowledge creation. In this paper, we analyzed the relationship among SECI model, Personal absorptive capacity of knowledge, and CoP. We also bring forward the conceptual model of Personal absorptive capacity of knowledge based on the CoP.
With the increasing amount of digital media being stored, shared and consumed on the Internet, more imaging applications are deployed online. However, the usability and use model of those applications are often less studied. In this paper, we present Snapfish Lab, an open online imaging community web site, to enable both imaging technologists and enthusiasts participate actively in exploring the usability...
