Automated methods for resource annotation are a clear necessity, as the success of the semantic Web depends on the availability of Web resources with meta data conforming to known standards and ontologies. This paper describes the WebCAT framework for automatically generating RDF descriptions of Web pages. We present a general view of the system and the algorithms involved, giving an emphasis to typical issues in processing Web data.

In this paper, we design and implement a P2P cooperative proxy caching system based on a novel P2P cooperative proxy caching scheme. To effectively locate the cached Web documents, a TTL-based routing protocol is proposed to manage the query and response messages in the P2P cooperative proxy cache system. Furthermore, we design a predict query-route algorithm to improve the TTL-based routing protocol by adding extra information in the query message packets. Our performance studies demonstrate that the proposed message routing protocols significantly improve the performance of the P2P cooperative proxy cache system, in terms of cache hit ratio, byte hit ratio, user request latency, and the number of query messages generated in the proxy cache system, compared to the flooding based message routing protocol.

Beyond serving as online diaries, Weblogs have evolved into a complex social structure, one which is in many ways ideal for the study of the propagation of information. As Weblog authors discover and republish information, we are able to use the existing link structure of blogspace to track its flow. Where the path by which it spreads is ambiguous, we utilize a novel inference scheme that takes advantage of data describing historical, repeating patterns of "infection." Our paper describes this technique as well as a visualization system that allows for the graphical tracking of information flow.

Ontologies are widely used for organising and sharing knowledge. But elaborating these resources is a heavy and time-consuming task. This paper is two-fold: it describes EADS DCS text-mining platform, in particular, its service to annotate documents with semantic tags and it presents its extension for incremental learning of ontologies. Domain experts are assisted in the ontology population task by recent machine learning techniques (i.e. conditional random fields). Comparisons are made between annotations from the ontology and from a trained CRF model, so as to detect candidate instances. An iterative process controlled by the experts results in knowledge discovery and constitution of an accurate ontology.

An artificial neural network model, capable of processing general types of graph structured data, has recently been proposed. This paper applies the new model to the computation of customised page ranks problem in the World Wide Web. The class of customised page ranks that can be implemented in this way is very general and easy because the neural network model is learned by examples. Some preliminary experimental findings show that the model generalizes well over unseen Web pages, and hence, may be suitable for the task of page rank computation on a large Web graph.

This paper describes an approach for a composition of Web services based on their semantic descriptions. The process section of OWL-S service descriptions is built with references to ontology concepts which represent service input and output data types. We present an engine that receives a request containing a concept (OC) corresponding to a service output and a set of concepts (ICs) corresponding to a service inputs. The engine produces a sequence of services whose first element has ICs as inputs and whose last element has OC as output. The result of the composition is described as a BPEL process.

In this work, we show that Kleinberg's hubs and authorities model (HITS) is simply principal components analysis (PCA; maybe the most widely used multivariate statistical analysis method), albeit without centering, applied to the adjacency matrix of the graph of Web pages. We further show that a variant of HITS, SALSA, is closely related to correspondence analysis, another standard multivariate statistical analysis method. In addition, to provide a clear statistical interpretation for HITS, this result suggests to rely on existing work already published in the multivariate statistical analysis literature (extensions of PCA or correspondence analysis) in order to analyse or design new Web pages scoring procedures.

The online recommendations are a popular presence in the Web sites world due to their potential to increase the customers' satisfaction. The ability to represent epistemic information about the clients' beliefs is important to understand their needs. This paper presents a recommender system based on reinforcement learning. The system represents concepts presented on a Web site by epistemic logical programs and uses a similarity measure between programs in order to facilitate generalization. A prototype of this system and experiments are presented.

With the development of Web technology and it is applied in education, Web-based learning support systems (WLSSs) have been adopted all over the world. This paper presents a formal evaluation model for WLSSs based on the method of fuzzy integrated evaluation. We concentrate on the commonly factors and elements that ensure and contribute to the learning course. The model is comprehensive and objective, so that it can be used to evaluate all WLSSs. Based on the proposed model, some WLSSs are evaluated and compared with each other. Some further research issues are also discussed.

It has been well documented that Web searchers have difficulties crafting queries to fulfill their information needs. In this work, we use a concept knowledge base generated from the ACM computing classification system to generate a query space that represents the query terms in relation to the concepts they describe and the other terms that are related to these concepts. A visual representation of this query space allows the user to interpret the relationships between their query terms and the query space. Interactive query refinement within this visual representation takes advantage of the user's visual information processing abilities, and allows the user to choose terms that accurately represent their information need. A preview of the search results from Google provides the user with an indication of the current state of their query refinement process. This work allows the user to take an active role in the information retrieval process, supporting the fundamental shift from information retrieval systems to information retrieval support systems.
