Despite the presence of software enabling communications and content sharing, they are not always shared among people inside networks. We present here an architecture aimed at helping people to share informations and find collaborators inside an organization. It is part of our PIAF framework, an intelligent agent system we use to develop recommender and personalization software. The main contribution of this paper is the introduction of principles of stigmergy and artificial ants to model data flows in a social network.
Nature-Inspired Dissemination of Information in P2P Networks

It is an easy task to subscribe to a social network, join one of the Web-based communities according to some personal interests and start to share content with all the people who do the same. It is easy once you solve two basic problems: select the network to join (go to hi5, facebook, myspace,…? join all of them?) and find/pick up the right communities (i.e., find a strict label to match non-strict centers of interest). An error of appreciation would result in getting too much of useless/non-relevant information. This chapter provides a study on the dissemination of information within groups of people and aim at answering one question: can we find an effortless way of sharing information on the Web? Ideally, such a solution would require neither the definition of a profile nor the selection of communities to join. Publishing information should also not be the result of an active decision but be performed in an automatic way. A nature-inspired framework is introduced as an answer to this question. This framework features artificial ants taking care of the dissemination of information items within the network. Centers of interest of the users are reflected by artificial pheromones laid down on connections between peers. Another part of the framework uses those pheromone trails to detect shared interests and creates communities.

The free-libre Sugar learning platform is now compatible with common GNU/Linux distributions such as Fedora, Mageia-Mandriva and Ubuntu. Recent XO laptops are more powerful but keep their original sturdy and low consumption design. OLPC tablets should be commercialized in 2013. Specific Sugar activities will complete already existing free (and sometimes libre) educational activities of Android. Résumé Nous présentons les développements récents du projet sans but lucratif OLPC. La plate-forme éducative libre Sugar est maintenant compatible avec les distributions GNU/Linux usuelles telles que Fedora, Mageia-Mandriva et Ubuntu. Les portables XO récents sont plus puissants mais gardent leur conception robuste et économe en énergie. Des tablettes OLPC devraient être commercialisées début 2013. Elles utiliseront le système Android en attendant l'adaptation de la plate-forme éducative libre Sugar. Des activités Sugar spécifiques compléteront les applications pédagogiques gratuites et parfois libres qui existent déjà sous Android.

From fragment to fabric - Dutch census data in a web of global cultural and historic information (CEDAR) is an ongoing (2011-2015) Dutch multidisciplinary national research project. It is funded by the Royal Netherlands Academy of Arts and Sciences (KNAW) as part of the Computational Humanities Programme. Its participants are Data Archiving and Networked Services (DANS), the VU University Amsterdam, the International Institute of Social History6 (IISH) and the Erasmus University Rotterdam.

The Eventseer web service was originally created to simplify this task by providing access to academic calls for papers in a semi-structured and searchable format. This paper describes the work being done to make the Eventseer data available as Linked Data, thereby further increasing its accessibility and usefulness to the scientific community. Details are given about the process of extracting necessary information such as event names and dates, deadlines and associated people, topics and organizations from the call for paper texts. The resulting mapping to a Linked Data RDF format and the modeling choices made are discussed. Examples of secondary use of Eventseer data are given; these include social network analysis of academic communities, altmetrics for measuring researcher impact, and automated modeling of topic hierarchies. Finally, a set of suggested improvements and known limitations are mentioned, along with plans for further improvement of the breadth and quality of the Linked Data.

Often, variable values of such statistical data come in a non-standardized way and represented by too narrow, concrete or wrongly typed literals. Generally, adequate and standard concept schemes for such variables (especially in very specific domains like historical religious denominations, or building types in the pre-industrial era) do not exist and need to be created. This is a manual task that requires lots of expert knowledge and time investment. We present a workflow that combines hierarchical clustering and semantic tagging to automatically build concept schemes in a data-driven and bottom-up way, leveraging lexical and semantic properties of the non-standard dimension values. We apply our workflow in two different use-cases and discuss its usefulness, limitations and possible improvements.

We argue that methods from computational intelligence (CI) can play an important role in solving these problems. In this paper we introduce and systemically discuss the typical application problems on the Semantic Web and discuss CI alternative to address the limitations of their underlying reasoning tasks consistently with respect to the increasing size, dynamicity and complexity of the data. Finally, we discuss two case studies in which we successfully applied soft computing methods to two of the main reasoning tasks; an evolutionary approach to querying, and a swarm algorithm for entailment.

Things are changing now and these boxes are being open for sharing the artefacts they contain. The question then raises of how to best share this artefacts on the Web. In this paper we discuss how Digital Archives can play a key role as a versatile data sharing platform exposing and interlinking all the artefacts of a given research process.

National Statistical Offices (NSO) encode knowledge to detect these inconsistencies in so-called edit rules. These days, there is an increasing number of statistical data being published and linked on the Web using the RDF Data Cube vocabulary. However, edit rules are hardly ever published together with data cubes on the Web. This causes two important problems: (a) quality of RDF Data Cube data cannot be assessed; and (b) reusability of edit rules is hampered. In this paper we present Linked Edit Rules (LER), a method that makes edit rules Web friendly and reusable as Linked Data. We show that LER can be easily linked, retrieved, reused, combined and executed to check quality and consistency of RDF Data Cubes, opening up the internal NSO validation processes to the Web.
