The project KiWi is concerned with knowledge management in Semantic Wikis and funded by the European Commission under the Project Number 211932 in the EU Seventh Framework Programme (FP7). KiWi's objective is to investigate how knowledge management in highly dynamic environments can be supported using Semantic Wiki technologies, and how Semantic Wikis can be improved to satisfy the requirements of knowledge management. For this purpose, KiWi will * implement an advanced knowledge management system based on the Semantic Wiki IkeWiki and extend it by improved, rule-based reasoning support, information extraction, personalisation, and advanced visualisations and editors * verify the system on two use cases in the areas of project knowledge management and software knowledge management, with flexible workflow models and specific support for the respective application areas.

KHarvester (Informal Knowledge Harvester) is a SOA layer which collects RDF data from web pages. It provides REST based Web Services for managing data available on Social Semantic Information Sources (SSIS): semantic blogs, semantic wikis, and JeromeDL (the Social Semantic Digital Library). These Web Services allow saving harvested data in the informal knowledge repository, and providing them in a form of informal Learning Objects (LOs) that are described accroding to LOM (Learning Object Metadata) standard. Also, IKHarvester is an extension to Didaskon system. Didaskon (διδάσκω - gr. teach) delivers a framework for composing an on-demand curriculum from existing Learning Objects provided by e-Learning services (formal learning). Moreover, the system derives from SSIS which provide informal knowledge. Then, the selection and work-flow scheduling of Learning Objects is based on the semantically annotated specification of the user's current skills/knowledge (pre-conditions), anticipated resulting skills/knowledge (goal) and technical details of the clients platform.

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

The SMW+ User Forum is an online community for users and developers of Semantic MediaWiki+ in a commercial or production environment with the purpose to improve and extend Semantic Media Wiki+. SMW+ Forum fuses the social networking aspect of Web 2.0 with semantic technologies.

Swirrl is a wiki-like application that was built using Semantic Web technologies and launched as a beta last week.

COSMO is the proposed Common Semantic Model, viewed as consisting of a lattice of ontologies which will serve as a set of basic logically-specified concepts (classes, relations, functions, instances) with which the meanings of all terms and concepts in domain ontologies can be specified. The most important function of the COSMO is to serve as a Foundation Ontology that has a sufficient inverntory of fundamental concept representations so that it can support utilities to translate assertions of fundamentally different ontologies into the terminology and format of each other. The use of a common set of defining concepts will permit accurate interoperability of knowledge-based systems using the logical relations of their ontologies as the basis for reasoning in the system. The COSMO can also be used as the starting ontology for creation of more specialized domain ontologies.

In ECOSPACE, the Semantically Interlinked Online Community (SIOC) is used to facilitate CWE interoperability [1, 2]. SIOC provides an ontology for representing rich data from the Social Web in RDF. The SIOC ontology was recently published as a W3C Member Submission, which was submitted by 16 organisations [3]. The SIOC Core ontology defines the main concepts and properties required to describe information from online communities on the Semantic Web. The main terms in the SIOC Core ontology are shown in Figure 1. The basic concepts in SIOC have been chosen to be as generic as possible, thereby enabling many different kinds of user-generated content to be described. Once proprietary CWE data is annotated with the SIOC ontology, it becomes interpretable by other CWEs. Based on this, a CWE Interoperability Architecture has been designed.

The OntologyDesignPatterns.org is a semantic web portal dedicated to ontology design patterns (OPs) for the Semantic Web developed in the context of the Neon project (http://www.neon-project.org).

SWiM is a semantic wiki for collaboratively building, editing and browsing a mathematical knowledge base. Its pages, containing mathematical theories, are stored in OMDoc, a markup format for mathematical knowledge. Our long-term objective is to develop a software that facilitates the creation of a shared, public collection of mathematical knowledge (e.g. for education) and serves work groups of mathematicians as a tool for collaborative development of new theories.

AceWiki is a semantic wiki that is powerful and at the same time easy to use. Making use of the controlled natural language ACE, the formal statements of the wiki are shown in a way that looks like natural English. In order to help the users to write correct ACE sentences, AceWiki provides a predictive authoring tool.

WikiProteins enables community annotation in a Wiki-based system. Extracts of major data sources have been fused into an editable environment that links out to the original sources. Data from community edits create automatic copies of the original data. Semantic technology captures concepts co-occurring in one sentence and thus potential factual statements. In addition, indirect associations between concepts have been calculated. We call on a 'million minds' to annotate a 'million concepts' and to collect facts from the literature with the reward of collaborative knowledge discovery. The system is available for beta testing at http://www.wikiprofessional.org

For the past few months I've been an active member of Twine.com; a beta semantic web app riddled with AI to help us organize, share and discover information. The beta is still under heavy construction, but at this point in time, I've migrated entirely from Del.icio.us, personal wikis and similar online services and over to Twine.

OntoWiki facilitates the visual presentation of a knowledge base as an information map, with different views on instance data. It enables intuitive authoring of semantic content, with an inline editing mode for editing RDF content, similar to WYSIWIG for text documents.

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.

"The ECOSPACE vision is to bring together semantic and social web (Web 2.0) through a user-centric interoperability approach towards the collaborative web or web 3.0!"

There is a growing community interest in applying Semantic Web and Web 2.0 technologies in health care and life sciences areas including the Health Care and Life Sciences Interest Group (HCLSIG ; http://www.w3.org/2001/sw/hcls/) and Medicine 2.0 (http://www.medicine20congress.com/). This has motivated us to explore how to intersect these two sets of technologies in the context of the HCLS Knowledge Base (KB).

The Object-Oriented Hypermedia Design Method (OOHDM) (and its successor, the Semantic Hypermedia Design Method, SHDM) allow the concise specification and implementation of hypermedia (web) applications. This is achieved based on various models describing information (conceptual), navigation and interface aspects of these applications, and the mapping of these models into running applications, in various environements.

Primary Objectives * Build a demo that spans from bench to bedside using RDF and OWL. * Explore the effectiveness of current tools. * Document our finding to help accelerate adoption of the Semantic Web.
