VoCamp is a series (hopefully) of informal events where people can spend some dedicated time creating lightweight vocabularies/ontologies for the Semantic Web/Web of Data. The emphasis of the event(s) is not on creating the perfect ontology in a particular domain, but on creating vocabs that are good enough for people to start using for publishing data on the Web. The intention is to follow a "paper first, laptops second" format, where the modelling is done initially on paper and only later committed to code. The VoCamp idea is heavily influenced by BarCamp, although the VoCamp should only have presentations where strictly necessary.

Through ANLoc, the African Network for Localization, the Kamusi Project is proud to be involved with a project to create Locales for 100 African languages. The following presentation provides an introduction to the initiative:

Sesat is an open sourced Search Middleware with federation capabilities and a built-in search portal framework. Sesat enables a single user query to be dispatched to multiple information sources. The result is analysed, weighted and presented to the user according to configurable business rules.

The Web is ephemeral. Pages change frequently, and it is nearly impossible to find data or follow a link after the underlying page evolves. We present Zoetrope, a system that enables interaction with the historical Web (pages, links, and embedded data) that would otherwise be lost to time. Using a number of novel interactions, the temporal Web can be manipulated, queried, and analyzed from the context of familar pages. Zoetrope is based on a set of operators for manipulating content streams. We describe these primitives and the associated indexing strategies for handling temporal Web data. They form the basis of Zoetrope and enable our construction of new temporal interactions and visualizations.

Wikipedia, the free online encyclopedia, has challenged the way that reference works are used and understood, and even the way that the collective enterprise of knowledge construction and circulation is itself conceptualized. The article presents an ethnographic study of Wikiversity, an educationally-oriented sister project to Wikipedia. It begins by providing an overview of the orientations and aims of Wikiversity, which seeks to provide for participants both open educational contents and an open educational community. It then undertakes a detailed examination of this project's emerging, overlapping communities and cultures by providing descriptions produced through a combination of ethnographic techniques. These descriptions focus on the experiences of a participant-observer in the context of an 11-week course developed and delivered via Wikiversity, titled Composing Free and Open Online Educational Resources. These descriptions are discussed and interpreted through reference to qualitative studies of the more developed dynamics of the Wikipedia effort - allowing this study to trace the possible trajectories for the future development of the fledgling Wikiversity project. In this way, this paper investigates the communal and cultural dynamics of an undertaking that - should it meet only with a fraction of Wikipedia's success - will be of obvious significance to education generally.

This paper presents two design patterns for the hypermedia domain: `Navigational Contexts' and `Information on Demand'. They are applied in two different aspects of hypermedia applications design: the design of healthy navigational structures and the design of understandable and usable hypermedia interfaces, respectively. These two patterns are part of an effort for developing a Pattern Language for that domain.

The Cultural Revival Dialog - Building the Europe of the Future Together - was organized by the European Movement Croatia in cooperation with the University of Oslo Knowledge Federation Project, on occasion of the 60th anniversary of the International European Movement. The invitation letter was sent to prominent Croatian researchers, policy makers and media workers, inviting them to a free and open dialog about the prospects for contemporary cultural revival. As always, the purpose of this Key Point Dialog was to come closer to the Key Point - an inspiring vision of the cultural revival, which The Club of Rome considered to be the solution to our global issues, or to the world problematique as they called them. This time we began our dialog by reflecting about a specific theme, the Sheng Zhen Qigong. The intention behind this reflection was to become aware of the nature of our present cultural turning point, of the obstacles that hinder us from changing course, and of the opportunities that a new direction may make available.

Jigsaw provides a collection of visualizations that each portray different aspects of the documents. We particularly focus on presenting the identifiable important entities (people, places, organizations, etc.) and their direct or indirect connections. Textual processing extracts the important entities from the documents and then the visualizations help an analyst to explore the relationships and connections among the entities. The system includes graph, calendar, scatterplot and and tabular connections-based views, as well as views of individual document's text and the report collections as a whole. Jigsaw essentially acts as a visual index onto the document collection, helping analysts identify particular documents to read and examine next.

A list of Beehive features, from a Beehive introduction session yesterday (presented by VP and Chief Architect, Oracle Collaborative Technologies, Terry Olkin): * Contacts * Messages (email) * Wiki * Tasks * Conferencing * IM (transcripts) * Calendar * Documents * Discussions

The confluence of computers, communications, and databases is quickly creating a distributed database where many applications require real-time access to both temporally accurate and multimedia data. This is particularly true in military and intelligence applications, but these required features are needed in many commercial applications as well. We are developing a distributed database, called BeeHive, which could offer features along different types of requirements: real-time, fault-tolerance, security, and quality-of service for audio and video. Support of these features and potential trade-offs between them could provide a significant improvement in performance and functionality over current distributed database and object management systems. In this paper, we present a high level design for BeeHive architecture and sketch the design of the BeeHive Object Model (BOM) which extends object-oriented data models by incorporating time and other features into objects, resulting in a highly reflective architecture.

The present research analyses the 'social visualization' tool Sense.us, a commercial interactive Web application in which U.S. Census data are visualized. Sense.us was developed as a tool for social data exploration and interaction, in which it would be worthwhile to pay attention to the socio-cultural values that have driven the collection and categorization of the underlying U.S. Census datasets. It is argued that closer attention to value driven U.S. Census statistics would greatly enhance the social appeal of Sense.us, and would be a logical next step in the development of online social visualization tools. In order to allow for explicit socio-cultural values of statistics in online visualizations, three strategies are offered: pro-active annotation; more attention to visual aesthetics; and, a tighter integration of user profiles and represented data.

IkeWiki is a new kind of Wiki (a Semantic Wiki ) developed by SalzburgResearch that allows users to annotate pages and links between pages with semantic annotations. Such annotations are useful because they give machines a certain amount of "understanding" of the content that goes beyond merely displaying the page. This information can then e.g. be used for context-specific presentation of pages, advanced querying, consistency verification or drawing conclusions. Currently, IkeWiki can make use of some of the knowledge represented in RDFS and OWL schemas to display enhanced navigation tools. Furthermore, we implemented a sample "biology ontology" that automatically displays a taxonomy box for biological objects. Although IkeWiki looks and behaves like Wikipedia/MediaWiki in many aspects, it is a complete rewrite, and the system design significantly differs from other Wikis. IkeWiki makes full use of Semantic Web technologies like RDF(S) and OWL using the Jena RDF store, and is implemented as an AJAX-based Rich Internet Application, based on the Dojo Toolkit

This is the official community gathering place and information resource for the OpenDocument Format (ODF) OASIS Standard (ISO/IEC 26300). Suitable for text, spreadsheets, charts, graphs, presentations, and databases, ODF frees documents from their applications-of-origin, enabling them to be exchanged, retrieved, and edited with any OpenDocument-compliant software or tool. This is a community-driven site, and the public is encouraged to contribute content.

Collaborative tagging describes the process by which many users add metadata in the form of keywords to shared content. Recently, collaborative tagging has grown in popularity on the web, on sites that allow users to tag bookmarks, photographs and other content. In this paper we analyze the structure of collaborative tagging systems as well as their dynamical aspects. Specifically, we discovered regularities in user activity, tag frequencies, kinds of tags used, bursts of popularity in bookmarking and a remarkable stability in the relative proportions of tags within a given url. We also present a dynamical model of collaborative tagging that predicts these stable patterns and relates them to imitation and shared knowledge.

By the year 2050, nearly 80% of the earth's population will reside in urban centers. Applying the most conservative estimates to current demographic trends, the human population will increase by about 3 billion people during the interim. An estimated 109 hectares of new land (about 20% more land than is represented by the country of Brazil) will be needed to grow enough food to feed them, if traditional farming practices continue as they are practiced today. At present, throughout the world, over 80% of the land that is suitable for raising crops is in use (sources: FAO and NASA). Historically, some 15% of that has been laid waste by poor management practices. What can be done to avoid this impending disaster?

The fishnet organization is a new organizational form which, among others, emerged in scientific literature in the field of organization theory in the past 20 years. Questions to ask here include: how to develop and maintain such a dynamic and heterarchic structure, described with the metaphor of a fisher's net, in a real organization? How to find knowledge and abilities which are fundamental in constructing such a structure? It seems obvious that without an adequate information system this task would be almost impossible. Thus we present organizational and information tools which are needed for the development and maintenance of this dynamic organization.

10 Pillars of Knowledge is a systematic map of human knowledge. It presents, at a glance, the structure of knowledge and the meaningful relations among the main fields.

The conference on Computational Model of Arguments (COMMA) originated from the ASPIC project, and is intended as a regular forum in which research related to computational aspects of argumentation will be presented.

I've set up this site to provide space for me to share ideas with a "Board of Directors", so I can get feedback on refining the ideas, and advice on how and when to share these ideas. Bootstrapping Collective Intelligence: This represents my response to Christina Engelbart's challenge during her presentation, and the Program For The Future challenge. GTD.brain. This is my entry to the contest for how people are using the PersonalBrain to implement David Allen's Getting Things Done methods: RESOLVING: This is a 3-D framework I've been developing, most influenced by Bill's Appreciation-Influence-Control philosophy. Combinatorial Modeling: applying combinatorial theory to assigning values based on models of N-node systems
