Being based on Web technologies, Linked Data is distributed and decentralised in its nature. Hence, for the purpose of finding relevant Linked Data on the Web, search indices play an important role. Also for avoiding network communication overhead and latency, applications rely on indices or caches over Linked Data. These indices and caches are based on local copies of the original data and, th...

The paper discusses the issue of views in the Web context. We introduce a set of languages for managing and restructuring data coming from the World Wide Web. We present a spe-ciic data model, called the Araneus Data Model, inspired to the structures typically present in Web sites. The model allows us to describe the scheme of a Web hypertext, in the spirit of databases. Based on the data model...

In this paper, the authors analyse how educational institutions behave in relation with the contents available through the Web. They also reflect on the features of the currently available information managers, from an educational point of view. They found there is a lack of tools for information management at low scale when it has to be used as a resource for teaching and learning whether at s...

More and more people rely on Web information and with the advance of Web 2.0 technologies they can increasingly easily participate to the creation of this information. Country-level politicians could not ignore this trend and have started to use the Web to promote them or to demote their opponents. This paper presents how candidates to a French mayor local election and with less budget have eng...

Web-based research support systems (WRSS) are a specific type of Web-based support systems (WSS) that support research activities for scientists. They are motivated by the challenges and opportunities of the Web, as well as the needs of scientists. The recent advancements of computer and Web technologies make the implementation of WSS feasible. A general framework of WSS is presented by conside...

The main role of medical and healthcare informatics is the manipulation of medical information and the dissemination of knowledge. The advent of the Web increased the pervasiveness of medical information and attracted the interest of both practitioners and patients. Web 2.0 in its turn brings people together in a more dynamic, interactive space. With new services, applications and devices, it p...

XML views are essential for managing XML data on the Web. Like views in traditional databases, XML views allow users to see data from different perspectives. Moreover, XML views are able to offer a structured interface over semistructured data and make it possible to integrate heterogeneous data source. In this paper, we describe a graphical case tool for designing XML views with the following ...

XML is emerging as a new major standard for representing data on the world wide web. Several XML storage models have been proposed to store XML data in different database management systems. The unique feature of model-mappingbased approaches is that no DTD information is required for XML data storage. In this paper, we present a new modelmapping-based storage model, called XParent. Unlike the ...

Performance-enhancing mechanisms in the World Wide Web primarily exploit repeated requests to Web documents by multiple clients. However, little is known about patterns of shared document access, particularly from diverse client populations. The principal goal of this paper is to examine the sharing of Web documents from an organizational point of view. An organizational analysis of sharing is ...

A large amount of publicly available Web pages are generated dynamically upon request, and contain links to other dynamically generated pages. This usually produces Web sites which can create arbitrarily many pages. This poses a problem to search engine managers: they need a rule to configure the search engine’s crawler in such a way that it stops downloading pages from each Web site at some de...
