SemKey: A Semantic Collaborative Tagging System

Problems related to synonymy, polysemy, different lexical forms, mispelling errors or alternate spellings, different levels of precision and different kinds of tag-to-resource association cause inconsistencies and reduce the efficiency of content search and the effectiveness of the tag space structuring and organization. They are mainly caused by the lack of semantic information inclusion in the tagging process. We propose a new way to describe resources: the semantic tagging. It allows user to state semantic assertions: each of them expresses a defined characteristic of a resource associating it with a concept. We present SemKey, a semantic collaborative tagging system, describing its global architecture and functioning along with the most relevant organizational issues faced. We explore the adequacy of the support offered by the entries of Wikipedia and WordNet in order to access to and reference concepts.

Semantify del.icio.us: automatically turn your tags into senses

In this paper, after a detailed analysis of the attempts made to improve the organization and structure of tagging systems as well as the usefulness of this kind of social data, we propose and evaluate the Tag Disambiguation Algorithm, mining del.icio.us data. It allows to easily semantify the tags of the users of a tagging service: it automatically nds out for each tag the related concept of Wikipedia in order to describe Web resources through senses. On the basis of a set of evaluation tests, we analyze all the advantages of our sense-based way of tagging, proposing new methods to keep the set of users tags more consistent or to classify the tagged resources on the basis of Wikipedia categories, YAGO classes or Wordnet synsets. We discuss also how our semanitied social tagging data are strongly linked to DBPedia and the datasets of the Linked Data community.

turístico, tanto para las empresas como para los destinos. A través de los blogs, las comunidades de
usuarios y las redes sociales, el turista puede recomendar o criticar los destinos y sus servicios
turísticos,  permitiendo, a la vez, que éstos puedan aprender a conocer mejor los gustos y los intereses
de sus clientes.
Pero la web 2.0 no sólo supone una ventaja en la interacción con el cliente, sino que también permite 
la creación, distribución e intercambio de información y conocimiento entre las empresas y los
órganos públicos gestores del turismo. En este sentido, en España han surgido ejemplos de empresas y
profesionales que han abierto sus bitácoras o blogs para reflexionar sobre la situación y las tendencias
del sector. Uno de los servicios de mayor éxito ha sido Turismo 2.0, una red social que ha conseguido
integrar profesionales de todo el abanico de subsectores turísticos, y en la cual se originan debates e
iniciativas de mejora e innovación tanto para la gestión privada de los servicios turísticos como en la
gestión pública y privada de los destinos.
Este “paper” pretende analizar los elementos principales que definen el cambio de paradigma en las
redes de conocimiento de los destinos turísticos, identificando aquellos que han de contribuir de
manera más destacada a la innovación, a la vez que se expondrán ejemplos en la práctica de esta
nueva estrategia de los destinos.

Six years later (2005-2011), OpenStreetMap and Google Earth (GE) are now full-fledged, crowdsourced ‘Wikipedias of the Earth’ par excellence, with millions of users contributing their own layers to GE, attaching photos, videos, notes and even 3-D (three dimensional) models to locations in GE. From using Twitter in participatory sensing and bicycle-mounted sensors in pervasive environmental sensing, to creating a 100,000-sensor geo-mashup using Semantic Web technology, to the 3-D visualisation of indoor and outdoor surveillance data in real-time and the development of next-generation, collaborative natural user interfaces that will power the spatially-enabled public health and emergency situation rooms of the future, where sensor data and citizen reports can be triaged and acted upon in real-time by distributed teams of professionals, this paper offers a comprehensive state-of-the-art review of the overlapping domains of the Sensor Web, citizen sensing and ‘human-in-the-loop sensing’ in the era of the Mobile and Social Web, and the roles these domains can play in environmental and public health surveillance and crisis/disaster informatics. We provide an in-depth review of the key issues and trends in these areas, the challenges faced when reasoning and making decisions with real-time crowdsourced data (such as issues of information overload, “noise”, misinformation, bias and trust), the core technologies and Open Geospatial Consortium (OGC) standards involved (Sensor Web Enablement and Open GeoSMS), as well as a few outstanding project implementation examples from around the world.

What can we learn about contemporary work and its collective forms of sociability from the rise of ‘rendez-vous' games on Internet ? Games can be useful tools for analyzing work on the condition that our understanding of the encounters between of these two types of activity is not limited to a common-sense interpretation in which games represent at worst a simple form of entertainment, at best, training for something more serious. On the basis of interviews with players of an online game, we show that forms of play vary with the work activity with which they are associated, and especially, on the presence or absencce of multi-activity, where interactions at a distance and heterogeneous solicitations occupy an important place. Examing gaming pratice during breaks enables us to see how employees manage to maintain the consistency of their activities in such professional contexts, and to understand the developing of new forms of sociability based mainly on shared life/work rhythms.

Résumé

Que peut nous apprendre l'essor des « jeux de rendez-vous » sur le travail contemporain et les collectifs qui s'y inventent ? Si le jeu peut constituer un bon analyseur du travail, c'est que l'intrication de ces deux activités ne se résume pas aux deux interprétations courantes, qui voient dans le jeu un divertissement ou un entraînement. En partant d'entretiens menés avec des joueurs d'un jeu en ligne sur internet, on montre que la forme prise par la pratique de jeu varie selon l'activité de travail où elle s'insère, en particulier selon la présence ou non d'une situation de multi-activité, où se multiplient les communications à distance et les sollicitations hétérogènes dans le cours de l'activité. Le jeu donne ainsi à voir le travail déployé pour maintenir une cohérence de l'activité dans les contextes professionnels, plus nombreux aujourd'hui, où les temps sont individualisés, les arrangements techniques, laissés à la responsabilité du travailleur, et les sollicitations hétérogènes. On comprend aussi que s'y développent des nouvelles formes de sociabilités essentiellement basées sur le partage de rythmes.

Semantic Web or Web 2.0? Socialization of the Semantic Web

by Jorge Morato

Jorge Morato, Sonia Sánchez-Cuadrado, Anabel Fraga and Yorgos Andreadakis. Semantic Web or Web 2.0? Socialization of the Semantic Web. First World Summit on the Knowledge Society. Athens, Sept. 2008

Web 2.0 and the Semantic Web are approaches that target the improvement of the Web through mechanisms for sharing information and resources. This document argues that Web 2.0 is not an immature stage of the Semantic Web but an orthogonal dimension of another Web aspect, the semantic. Unfortunately, both dimensions are not independent; the more developed a semantic representation of a system is, for being more useful for the Semantic Web, the more distant it is to the Web 2.0. A semantic system highly formalized is less intuitive and less usable for users. The different possible evolutions are: the convergence of both Webs, their co-existence and the autonomous evolution of the Social Web towards other semantic solutions. In order to enable a real Social Semantic Web eight proposals are sited and discussed.

This paper describes how a series of participatory design activities allowed postgraduate students in education, social sciences and computer sciences to contribute to the development of new Web 2.0 tools to enhance an existing virtual collaboration environment. In the course of these design activities, students reflected on and articulated the existing and emerging academic practices in which they were involved as they managed their transition from undergraduate courses to postgraduate research. The tools that were developed can therefore be seen as reifications of participants' emerging academic practices and the challenges they face as new researchers. This highlights the need for flexible design approaches and adaptable technological frameworks if Web 2.0 tools are to be successfully integrated into higher education settings.

A Socio-epistemological Framework for Scientific Publishing

Simon, J. (2010). A Socio-Epistemological Framework for Scientific Publishing, Social Epistemology, 24 (3), 201-218.

This framework is informed by social epistemology, science and technology studies (STS) and feminist epistemology. Its core consists of a tripartite classification of socio-technical epistemic systems based on the mechanisms of closure they employ to terminate socio-epistemic processes in which multiple agents are involved. In particular I distinguish three mechanisms of closure, integration, aggregation and selection, and argue that they correspond to three different types of epistemic sociality. Different systems can employ different mechanism of closure or combinations thereof. Yet each mechanism has its own epistemic merits, depends on specific social, technical and epistemic prerequisites, has different strengths and weaknesses, and is optimal for different epistemic tasks. The aim of my analysis is twofold. Distinguishing different modes of epistemic sociality is a way for me not only to put forward a more nuanced framework for analysing socio-epistemic practices, such as web-based scientific publishing and scholarly communication. It can also serve as the theoretical basis for improving them.

Knowing Together: A Social Epistemology for Socio-Technical Epistemic Systems

In many of these applications people are engaged in epistemic activities, such as the dissemination, organization or creation of knowledge. The goal of this thesis is to analyze the epistemological relevance of such epistemic social software. Because communication and interaction between multiple agents seems to be the key to understand the epistemic processes within such systems, social epistemology, the philosophical discipline exploring the ways and the extent to which knowledge is social, was chosen as a theoretical framework. However, none of the existing comprehensive social epistemologies delivers a sufficient framework to analyze epistemic social software. Therefore, I have developed a new socio-epistemological framework to analyze epistemic social software which is rooted in socio-epistemological discourse, but amends it with insights from the field of Science and Technology Studies (STS).

My framework is founded on a tripartite classification of socio-technical epistemic system based on the mechanisms they employ to close socio-epistemic processes. These three mechanisms are integration, aggregation and selection. With this classification I do not aim at reducing the differences between systems to their mechanisms of closure. However, I argue that the classification based on this indicator is heuristically fruitful. Systems employing different mechanisms of closure depend on different social, technical and epistemic prerequisites, have different strengths and weaknesses and are optimal for different epistemic tasks. My model puts a fact into the focus that has been neglected so far in social epistemology: the technical and its relationship to the social and the epistemic. Since most epistemic practices are nowadays pervaded by technologies, such a consideration of the role of technologies in these practices seems to be indispensable for any social epistemology that aims at being not only normatively appropriate, but also empirically adequate.
