We present a consistent and transparent caching system for dynamic web pages produced by a server-side application using a back-end database. Cached pages always reflect current database values. No intervention from the programmer is necessary to implement ...
The link structure of the Web graph is used in algorithms such as Kleinberg's HITS and Google's PageRank to assign authoritative weights to Web pages and thus rank them. In HITS, a solid theoretical model is lacking and the algorithm often leads to non-uni ...
In the last three decades the management of information technologies has become a major issue in most organizations. In this context, virtual communities (VC), as a means to technologically foster collective social exchanges, are often proposed as viable s ...
This paper introduces a personalized content preparation and delivery framework for universal multimedia access. This framework has a wealth of potential applications in broadcasting, the World Wide Web and mobile telecommunication. Content preparation dea ...
Market forces are continuously driving public and private organisations towards higher productivity, shorter process and production times, and fewer labour hours. To cope with these changes, organisations are adopting new organisational models of coordinat ...
Previous studies of the Web graph structure have focused on the graph structure at the level of individual pages. In actuality the Web is a hierarchically nested graph, with domains, hosts and Web sites introducing intermediate levels of affiliation and ad ...
Most of new databases are no more built from scratch, but re-use existing data from several autonomous data stores. To facilitate application development, the data to be re-used should preferably be redefined as a virtual database, providing for the logica ...
We present a new technique of annealing the EM algorithm to allow for its tractable application to fitting models which include graph structures like assignments. The method, which can be generally used to sparsify dependence models, is applied to solve th ...
This paper presents results of our research that targets the improvement of workgroup efficiency with technological support for the management of group-related information. We built a software tool that enables all the people in a workgroup to work with in ...
Until recently, most data integration techniques involved central components, e.g., global schemas, to enable transparent access to heterogeneous databases. Today, however, with the democratization of tools facilitating knowledge elicitation in machine-pro ...
