Weerkat: An extensible semantic wiki (original) (raw)
Web Semantics: Science, Services and Agents on the World Wide Web, 2008
Everyone agrees that user interactions and social networks are among the cornerstones of "Web 2.0". Web 2.0 applications generally run in a web browser, propose dynamic content with rich user interfaces, offer means to easily add or edit content of the web site they belong to and present social network aspects. Well-known applications that have helped spread Web 2.0 are blogs, wikis, and image/video sharing sites; they have dramatically increased sharing and participation among web users. It is possible to build knowledge using tools that can help analyze users' behavior behind the scenes: what they do, what they know, what they want. Tools that help share this knowledge across a network, and that can reason on that knowledge, will lead to users who can better use the knowledge available, i.e., to smarter users. Wikipedia, a wildly successful example of web technology, has helped knowledge-sharing between people by letting individuals freely create and modify its content. But Wikipedia is designed for people-today's software cannot understand and reason on Wikipedia's content. In parallel, the "semantic web", a set of technologies that help knowledge-sharing across the web between different applications, is starting to gain attraction. Researchers have only recently started working on the concept of a "semantic wiki", mixing the advantages of the wiki and the technologies of the semantic web. In this paper we will present a state-of-the-art of semantic wikis, and we will introduce SweetWiki, an example of an application reconciling two trends of the future web: a semantically augmented web and a web of social applications where every user is an active provider as well as a consumer of information. SweetWiki makes heavy use of semantic web concepts and languages, and demonstrates how the use of such paradigms can improve navigation, search, and usability.
SweetWiki: semantic web enabled technologies in Wiki
2006
Wikis are social web sites enabling a potentially large number of participants to modify any page or create a new page using their web browser. As they grow, wikis suffer from a number of problems (anarchical structure, large number of pages, aging navigation paths, etc.). We believe that semantic wikis can improve navigation and search. In SweetWiki we investigate the use of semantic web technologies to support and ease the lifecycle of the wiki. The very model of wikis was declaratively described: an OWL schema captures concepts such as WikiWord, wiki page, forward and backward link, author, etc. This ontology is then exploited by an embedded semantic search engine (Corese). In addition, SweetWiki integrates a standard WYSIWYG editor (Kupu) that we extended to support semantic annotation following the "social tagging" approach made popular by web sites such as flickr.com. When editing a page, the user can freely enter some keywords in an AJAX-powered textfield and an auto-completion mechanism proposes existing keywords by issuing SPARQL queries to identify existing concepts with compatible labels. Thus tagging is both easy (keyword-like) and motivating (real time display of the number of related pages) and concepts are collected as in folksonomies. To maintain and reengineer the folksonomy, we reused a web-based editor available in the underlying semantic web server to edit semantic web ontologies and annotations. Unlike in other wikis, pages are stored directly in XHTML ready to be served and semantic annotations are embedded in the pages themselves using RDF/A. If someone sends or copy a page, the annotations follow it, and if an application crawls the wiki site it can extract the metadata and reuse them.
Bringing the “Wiki-Way ” to the Semantic Web with
2008
Abstract. The Wiki and the Semantic Web can be compared as two different approaches to capturing knowledge, where the former trades away precise, explicit, and internally consistent semantics for speed and simplicity. Any attempt to bridge these two approaches has to either somehow reconcile these trades-off or make compromises one way or the other. This paper describes how Rhizome, an open source application framework for developing “Semantic Wiki ” applications, attempts to bridge these approaches. Rhizome includes a text formatting language called ZML whose syntax is similar to text formatting languages found in most Wikis but with enhancement to make it easy for users to express explicit and arbitrary semantics. Rhizome relies on “shredding”, a flexible framework for specifying rules for characterizing semi-structured content with RDF and providing an ontology that can precisely describe the relationship between the source content and the resulting statements. 1
Semantic wiki as a lightweight knowledge management system
The Semantic Web …, 2006
Since its birth in 1995, Wiki has become more and more popular. This paper presents a Semantic Wiki, a Wiki extended to include the ideas of Semantic Web. The proposed Semantic Wiki uses a simple Wiki syntax to write labeled links which represent RDF triples ...
On integrating a semantic wiki in a knowledge management system
Citeseer
The use of knowledge management systems is often hampered by the heavy overload for publishing information. In particular, uploading a document and then profiling it with a set of meta-data and keywords is a tedious and time-consuming activity. Therefore, one of the main goals for such systems should be to make publishing of explicit knowledge as natural as possible. In the project described in this paper, we exploit a semantic wiki editor to support document publishing by means of textual descriptions augmented by ontology-defined annotations. Such annotations are then managed as entries in metadata profiles. Moreover, we can publish semantic-wiki-based documents that do not require any further activity to be profiled and included in a knowledge base as they are self-describing. The semantic wiki project is part of a collaborative knowledge management system that has been developed to support project teams and communities of interest.
Towards an Interlinked Semantic Wiki Farm
2008
This paper details the main concepts and the architecture of UfoWiki, a semantic wiki farm -i.e. a server of wikis -that uses form-based templates to produce ontology-based knowledge. Moreover, the system allows different wikis to share and interlink ontology instance between each other, so that knowledge can be produced by different and distinct communities in a distributed but collaborative way.
Semantic Wikis and the Collaborative Construction of Ontologies: Case Study
Ontologies are complex artifacts. They should seek consensus on the use of a set of modeled concepts. Some authors propose that these devices would be beneficial if they were built collaboratively. This article aims to address the use of a semantic wiki as an alternative to the collaborative construction of ontologies, and describes its ontological structure. Wikis are known as tools for collaborative construction of content. The semantic wiki is a research effort to integrate the concepts of wikis with the semantic web. The case study presented shows an implementation in Semantic MediaWiki: the best known and most used semantic wiki features by the academic community and the organizational environment.
WikiApp–Engineering of Domain-specific Wiki Applications
ABSTRACT Since its inception in the early 2000s, Wiki technology became a ubiquitous pillar for enabling large-scale collaboration. However, the Wiki paradigm was mainly applied to unstructured, textual content thus limiting the content structuring, repurposing and reuse. More recently with the appearance of Semantic Wiki's the Wiki concept was also applied and extended towards semantic content with adverse effects on scalability.

This paper describes an approach to the design and implementation of ontology driven dynamic web sites combining ontologies and wiki technologies. The core of the architectural solution proposed is completely based on ontologies rather than on more traditional forms of persistent data storage facilities, such as relational databases. This approach provides a flexible support to the design and implementation of web portals in which navigation schemes are not entirely predetermined but are instead influenced by actual relationships among the contents of the ontology, that are used to generate web pages as well as hyperlinks. A wiki technology is integrated with this approach in order to create pages not directly derived by elements of the ontology, but also to enrich the textual contents with suitable formatting, images and hyperlinks. The application of this approach to the realization of a web portal is also described; the portal is devoted to enable a number of scientific communities to share archaeological knowledge about the Silk Road domain.
