In this paper, based on the feedback mechanism from perspective of network groups, evolutionary characteristics and laws group networks under information dissemination are studied. First, is divided into groups different sizes, each given a dynamically changing activity positive degree response to categories information. Second, feedback-based model in developed, which takes account differences...

their help in finding and understanding exciting practical research problems. This work would not have been possible without them.

Given a social network, we are interested to determine k seeds that maximize the dissemination of information. Based on the principle of homophily, communities play an important role since information can be disseminated to communities via the seeds. We introduce a new mechanism for detecting communities satisfying the pertinent criteria for communities and information dissemination. We demonst...

Using autonomous intelligent agents that converse based on mutually accepted ontologies distributed entities can share and disseminate knowledge across system and organization boundaries. By using ontologies that are expressed in rst order predicate-logic participating agents can query and declare knowledge in a very high-level fashion that goes beyond mere data sharing. This high-level concept...

for goal of transparency, listed companies are required to disclose their significant events, quarterly reports and the decisions taken in their general meetings. of course, when the dissemination of information might prejudice a company’s interests, it can withhold the disclosure on condition that it keeps the information confidential. this article, by using american and english experiences, s...

This paper examines the construction of distributed information systems that incorporate the ability to push data out to clients (i.e., dissemination) in addition to having clients pull data from servers. One key issue that distinguishes such dissemination-based information systems (DBIS) from more traditional ones is communications asymmetry. Asymmetry arises in many new applications due to bo...

This paper describes Transparent Replication through Invalidation and Prefetching (TRIP), a self tuning data replication middleware system that enables transparent replication of large-scale information dissemination services. The TRIP middleware is a key building block for constructing information dissemination services, a class of services where updates occur at an origin server and reads occ...

Wireless sensor networks constitute an emerging technology that has received recently significant attention both from industry and academia. On the one hand, there is an ever-widening range of attractive applications (e.g., disaster and environmental monitoring, wildlife habitat monitoring, target tracking, intrusion detection, security surveillance) sensor networks can be used for. On the othe...

Much climate data are available that can only be utilized if there is a flow of information to agri-business and farmers. As dissemination is the distribution of information, two-way communication channels are a necessity. The content of the message must be relevant to the decisions of the client. The process should involve the identification of climate sensitive decisions and interactions betw...
