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 ...
Semantic Wiki as a Light-Weight Metadata Management System
人工知能学会全国大会論文集, 2006
For the development of technologies for Semantic Web, machine-understandable metadata such as RDF is essential. Constructing RDF triples in a Wiki environment can be done by enabling the writing of labeled links. The labeled link represents the RDF property that links the RDF subject with its object. In a Semantic Wiki environment, users can write and edit RDF triples even though users have no knowledge about it. Semantic Wiki can be used for lightweight metadata management, and is useful to bridge the gap between non-technical users and Semantic Web technology.
Semantics on demand: Can a Semantic Wiki replace a knowledge base?
2008
In the same way that Wikis have become the mechanism that has enabled groups of users to collaborate on the production of hypertexts on the web, Semantic Wikis promise a future of collaboration on the production of semantically linked and ontologically structured hypertexts. In this paper we describe our efforts to convert an existing ontologically structured web site called Framework Reference Model for Assessment (FREMA) into a Semantic Wiki specifically to enable community contribution.
ODEWiki: A Semantic Wiki That Interoperates with the ODESeW Semantic Portal
2008
We present ODEWiki, a technology for the development of Semantic Wikis, which has a combined set of added-value features over other existing semantic wikis in the state of the art. Namely, ODEWiki interoperates with an existing semantic portal technology (ODESeW), it manages inconsistencies raised because of the distributed nature of knowledge base development and maintenance, it uses RDFa for the annotation of the resulting wiki pages, it follows a WYSIWYG approach, and it allows decoupling wiki pages and ontology instances, that is, a wiki page may contain one or several ontology instances. Although some of these features appear in some of the state-of-the-art semantic wikis, but they are not combined together in a single solution.
Techniques, Methods, and Applications, 2008
The wiki concept is ten years old this year but has attained public success only recently, thanks to Wikipedia. However, in the intranet world, several studies have shown that the usage of wikis is subject to debate. Acceptance of such open, low-structured collaborative tools is not the rule. There are different reasons for explaining such low acceptance: social reasons (corporate culture may not be adapted) but also usability reasons (the wiki is not structured enough, it is hard to navigate and find relevant information, the wiki markup language used by most wiki engine makes people reluctant to contribute to the wiki, etc.).
