This paper describes automatic Web-page classification by using machine learning methods. Recently, the importance of portal site services is increasing including the search engine function on World Wide Web. Especially, the portal site such as for Yahoo! service which hierarchically classifies Web-pages into many categories is becoming popular. However, the classification of Web-page into each...

Web portal software is relatively easy to set up and populate from the perspective of the end-user, but it leaves the back-end database devoid of subject domain semantics due to the requirement for a generic implementation. This approach seriously hampers effective search capabilities to retrieve relevant information. Ontology-based data access (OBDA) could, in theory, solve this problem throug...

The combination between ubiquitous computing environments and ambient displays enables a broad range of new scenarios for situated interaction. In this paper, we describe our web based approach for situated displays. The concept of situated portal is introduced as a web portal that is targeted for presentation at a specific situation and that is based on interaction metaphors that are radically...

Securing web-based systems involves a whole host of security components and practices, such as managing user digital identities, user authorizations, creating a web portal, implementing single sign-on, managing and monitoring servers and other resources critical to the enterprise web. This paper describes some of the real world challenges encountered in implementing enterprise web security, and...

A web based portal acting as a presentation layer to the Grid allows us to provide a transparent means of access to Grid resources. Our previous experiences in developing Grid portals have shown that there is a need to draw a clear high-level picture of the architecture. This could be defined using the J2EE component-oriented architecture, which enables a clear separation between the presentati...

The paper presents a Web Portal for measurement application based on GRID Service as an innovative solution to provide researchers with a “collection” of measurement algorithms characterized by huge computational burden. In its current version, the portal allows the execution of two different algorithms (i.e. estimation of spectral density power and instantaneous frequency). Other functionaliti...

Based on the cognitive psychology of selective attention and priming effect, and visual display effect, this research aims to explore how banner advertisements in the portal sites affect brand communication after end user enter the web. This study uses online SSI Web questionnaire and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method. The prime age group selection c...

This article presents the semantic portal MUSEUMFINLAND for publishing heterogeneous museum collections on the Semantic Web. It is shown how museums with their semantically rich and interrelated collection content can create a large, consolidated semantic collection portal together on the web. By sharing a set of ontologies, it is possible to make collections semantically interoperable, and pro...
