The SKOS API is a Java interface and implementation for the W3C Simple Knowledge Organisation System SKOS. For more information about SKOS see here. An implementation of the SKOS API is provided which uses the OWL 2 API, at present you will need to obtain the OWL API seperately from the OWL 2 website. [UPDATE 12-09-2011] The current release of the SKOS API has been deprecated, a new version_3 developer branch is available in the SVN repository that works with the latest OWL API v3.
For more information please contact the user group at skos-dev@googlegroups.com
The SKOS API is open source and is available under the LGPL License
The SKOS API includes the following components:
An API for the major SKOS constructs and an efficient in-memory reference implementation based on the OWL 2 API
Abstract data model for working for SKOS that avoids commitment to any of the concrete syntaxes, such as RDF
RDF/XML parser and writer
OWL/XML parser and writer
OWL Functional Syntax parser and writer
Turtle parser and writer
Support for extending the underlying SKOS data model via the OWL 2 API
Support for integration with reasoners such as Pellet and FaCT++
Range of convenience methods for working with SKOS
ThManager is an Open Source Tool for creating and visualizing SKOS RDF vocabularies, a W3C initiative for the representation of knowledge organization systems such as thesauri, classification schemes, subject heading lists, taxonomies, and other types of controlled vocabulary. ThManager facilitates the management of thesauri and other types of controlled vocabularies, such as taxonomies or classification schemes. The tool has been implemented in Java and has the following features:
Multi-platform (Windows, Unix). As it has been developed in Java and the storage of metadata records is managed directly through the file system, the application can be deployed in any platform with the minimum requirement of having installed a Java virtual machine.
Multilingual. The application has been developed following the Java internationalization methodology. Nowadays, there are Spanish and English versions. With little effort, other languages could be supported.
Selection and filtering of the thesauri stored in the local repository.
Description of thesauri by means of metadata in compliance with a Dublin Core based application profile for thesaurus (See application profile) . These metadata can be either visualized in HTML or edited through a form.
Visualization of thesaurus concepts. The visualization interface includes the following widgets:
Alphabetic viewer: It provides the list of thesaurus concepts alphabetically ordered in the selected language.
Hierarchical viewer: It provides a tree showing the hierarchical structure of thesaurus concepts.
Concept viewer: For a selected concept it shows all the properties allowing additionally the navigation to the related concepts by means of hyperlinks.
Search tool: It facilitates search of concepts. The searching process is based on preferred labels allowing the following criteria: "equals", "starts with" and "contains".
Edition of thesaurus content. The tool provides an edition interface to modify the content of a thesaurus: creation of concepts, deletion of concepts, and update of concept properties.
Exchange of thesauri according to SKOS format. The export operation includes the export of thesaurus metadata.
Extraction of related concepts in WordNet. It generates an automatic mapping of thesaurus concepts against the concepts of Wordnet lexical database.
On-line help by means of PDF visualization.
DBpedia is a community effort to extract structured information from Wikipedia and to make this information available on the Web. DBpedia allows you to ask sophisticated queries against Wikipedia, and to link other data sets on the Web to Wikipedia data. We hope this will make it easier for the amazing amount of information in Wikipedia to be used in new and interesting ways, and that it might inspire new mechanisms for navigating, linking and improving the encyclopaedia itself.
Freebase is an open, Creative Commons licensed repository of structured data of more than 12 million entities.
An entity is a single person, place, or thing. Freebase connects entities together as a graph.
Ways to use Freebase:
* Use Freebase's Ids to uniquely identify entities anywhere on the web
* Query Freebase's data using MQL
* Build applications using our API or Acre, our hosted development platform
Freebase is also a community of thousands of data-lovers, working together to improve Freebase's data. Learn how to contribute, join our mailing list, or find out more on our community page.

E-travel is comprehensive framework for delivering personalized travel services using agent infrastructure based on our works in agent-related fields: Multimodal Communication Between Users and Software Agents and Modelling User on the Basis of Interactions with a WWW Based System. The system utilizes many existing up-to-day technologies related to the term of Semantic Web: JADE agent platform together with Jena semantic framework for processing ontology demarcated data. For easy and type safe access to ontology Jastor (Java beans generator from Web Ontologies (OWL)) has been used. Raccoon server provides a way to transform ontological data into browser-readable forms.
Our solution addresses set of the following problems:
* Connecting synchronous HTTP protocol with asynchronous nature of software agents.
* Web browser and mobile interface providing natural access to the multi-agent system.
* Separation of data and view thanks to: Model-View-Controller architecture, ontologies and Raccoon server for transforming data into view.
* Content personalization basen on user modelling, including: stereotyping, user profile learning and exploitation.
OpenCyc is the open source version of the Cyc technology, the world's largest and most complete general knowledge base and commonsense reasoning engine. OpenCyc can be used as the basis of a wide variety of intelligent applications such as:
* rapid development of an ontology in a vertical area
* email prioritizing, routing, summarization, and annotating
* expert systems
* games
to name just a few.
OWL reasoner engines can contribute with the semantic enrichment over ontologies. The manner in which this knowledge is represented in OWL has been an obstacle to incorporate this semantic features in the object-oriented paradigms. JASB architecture pretends to be a bridge for joining this two different worlds. This platform offers a connection point in which the object instances of the object-oriented programming could have semantic features provides by mean of the reasoning processes available in OWL arena.
The architecture is composed by two clearly differenciated tools, each one is focussing on different objective.
In the logical sequence of a software development, the first tool covers the statical aspect of the inclusion of semantic features into object-oriented application. Thus, in the following picture can be seen the architecture for thisthe first tool, the JASB compiler.
