“…This layer provides a lightweight, string-based interface to communicate with the front-end, stores the ontology permanently in a database, and is able to handle queries. COW uses the ontology framework KAON [2] to implement the interface of the abstraction layer. A useful feature of KAON is the evolution log, a list stored in a meta-ontology where all ontology changes are logged.…”

“…Query templates are embedded into normal wiki text (1). COW renders this query as a question with forms to be filled out by the user (2). The user has the possibility to execute the query and view the result (3a) or to click on an instance to see further information (3b).…”

“…COW, Combining Ontologies with Wikis 1 , is a novel approach to build a semantic wiki, by bringing together two different concepts: easy content evolution with the help of wikis, and formal knowledge representation using ontologies. We use the KAON tool suite [2] as back-end for an ontology editor and a query processor; a simple text wiki engine complements the system's functionality. Our approach is different from other semantic wikis in two aspects: The ontology data is edited and stored outside the text wiki, and we implemented so-called query templates, which can be particularly useful for inexperienced users (figure 1).…”

Abstract. We present an architecture for combining wikis containing hypertext with ontologies containing formal, structured information. A web-based ontology editor that supports collaborative work through versioning, transactions and management of simultaneous modifications is used for ontology evolution. In wiki pages, ontology information can be used to render dynamic content and answer user queries. Furthermore, query templates are introduced that simplify the use of queries for inexperienced users. The architecture allows easy integration with existing ontology frameworks and wiki engines. The usefulness of the approach is demonstrated by a prototypical implementation as well as a small case study.

Abstract. Information Portals have gathered lot of attention among many organizations interested in a single point of access to their information and services. But developing portals from scratch is sometimes too expensive, so many vendors have proposed frameworks to make it affordable. Notwithstanding the frameworks the market offers seem stuck in a simplicity vs. flexibility trade off imposed by the Web technologies they are built with. Therefore we believe that a technology change is required and that Semantic Web technology can play a key role in developing a new, Semantic, generation of simpler and, at the same time, flexibler frameworks for Organizational Information Portal.

“…This global schema has two main roles in the mediation process: 1) acting as semantic framework for the mapping process, and 2) describing the complete universe of queries for the mediated database set. The use of ontologies for database integration has been widely studied and implemented in projects such as Ontofusion-carried out in our research lab [3] -, TSIMMIS [4] and KAON [5] among others.…”
