This paper studies the problem of extracting data from large numbers of semi-structured web pages. The fact that many websites have enormous pages generated dynamically from a underlying structured source like a database makes it feasible to induct a common template for similar web pages and then extract data accordingly. Previous work on this problem has limited practical utility because of either...
Electronic Commerce has offered a convenient way for people to go shopping on the Internet. However, it is difficult for Internet customers to select a valuable item from the great number of various products available on line. When we use a keyword and search in a EC website, the ranking algorithm of products is usually based on statistics or simply the shop manager's preference, which does not fully...
The Tactical Internet (TI) is a new and highly maneuverable network, so traditional network management (NM) methods can't solve its NM well, new methods needs to be explored. In this paper, the modeling of TI NM was researched at first, the action model, function model and organizing model were established and they settled the framework of TI NM. Secondly, the frequency planning of TI NM was researched,...
Cloud Storage has been increasing in popularity recently due to per-use pricing and elastic scalability, providing a significant advantage over the typical acquisition and deployment of equipment that was previously required. The effect has been a shift to outsourcing of not only equipment setup, but also the ongoing IT administration of the resources as well. In this paper, we describe the design...
The publish/subscribe paradigm provides a loosely coupled form of interaction that is well suitable for the large-scale distributed systems. In this paper, we introduce the semantic Web technologies into the publish/subscribe systems and propose a new type of publish/subscribe system. In the system, concept models are represented as ontologies, events are represented as RDF graphs, and subscriptions...
The design of micro-mobility management protocols stands out as an important challenge in integrating wireless networks into the IP-based Internet, especially when such networks are deployed for real-time multimedia applications. We present a new load balancing hierarchical model for micro-mobility management for the wireless access network. The scheme includes a novel anchor selection algorithm....
