MapPSO

Fri, 26 Sep 2008 18:41:18 +0200

MapPSO is a tool for Ontology Alignment, which uses Discrete Particle Swarm Optimisation. Revisiting the alignment problem as an optimisation problem, MapPSO uses a particle swarm to search for the optimal alignment. The algorithm is massively parallel and adapts naturally on parallel architectures.

OWL Benchmarking

Mon, 29 Oct 2007 16:32:47 +0100

OWL benchmarking aims to provide guidance for selecting the appropriate reasoner for a given application scenario. In order to so, the experiments are done based on some datasets with different fragments such as RDFS, OWL DL. Based on the benchmark results we identify which reasoners are most adequate for which classes of ontologies and corresponding reasoning tasks.

NeOn Toolkit

Fri, 18 May 2007 14:40:01 +0200

NeOn is a 14.7 million Euros project involving 14 European partners and co-funded by the European Commission’s Sixth Framework Programme under grant number IST-2005-027595. NeOn started in March 2006 and has a duration of 4 years. Our aim is to advance the state of the art in using ontologies for large-scale semantic applications in the distributed organizations. Particularly, we aim at improving the capability to handle multiple networked ontologies that exist in a particular context, are created collaboratively, and might be highly dynamic and constantly evolving. In this portal you can download the source code of the NeOn Toolkit. If you just to use it please go to the project homepage to find the latest executables.

Pattern Learner for Ontology Learning

Wed, 01 Mar 2006 15:46:50 +0100

Pronto, is a bootstrapping based relation extraction system. Given a small set of example facts (e.g. "Paris is located in France.", "Bejing is located in China") it is able to come up with a large amount of facts of that kind (e.g. a huge lists of cities and where they are located). To do so, Pronto considers the way the relations are mentioned in the text (i.e. what stands around "Paris" and "France" when these words occurr together). We set up Pronto to discover relations in this test Wikipedia between page titles and hyperlinks. When it discovers new facts, Pronto generates the questions, you will find on the bottom of the pages. The answers you give to these questions are used as confirmation of the results before they are written into the wiki and as feedback to improve output in the next iteration of the system.

If you are interested in the topic, you are invited to read the following research paper:

TARTAR

Tue, 10 Jan 2006 00:20:06 +0100

TARTAR - Transforming ARbitrary TAbles into fRames

Efficient automatic information handling has become increasingly important in information society. Most information on the Web is presented in the form of semi-structured or unstructured documents, encoded as a mixture of loosely structured natural language text and template units. The lack of metadata, which would precisely annotate the structure and semantics of documents, and ambiguity of natural language makes automatic computer processing very complex. The Semantic Web aims to overcome this bottleneck.

The contribution of this software package presents a novel method for automatic generation of knowledge models such as ontologies from arbitrary tabular structures found on the Web. The method is based on a grounded cognitive table model introduced by Hurst. The methodology is stepwise instantiated in four steps. In the first step, a table is transformed into regular matrix form. In the following two steps the table is handled from a structural and functional, and in the last step from a semantic point of view. The outcome of the method is threefold: a knowledge frame, an ontology, and a knowledge base, all encoded in an F-Logic representation language. A system is implemented in Java language, and consists of approximately 15.000 lines of code. In order to fully exploit (i.e. for query answering) the outcomes produced by the system, one can use an inference engine that supports F-Logic, like OntoBroker.

ONTHOLOGY

Most ontologies today exist in pure form without any additional information, e.g. authorship or domain specific information. The proposed Ontology Metadata Vocabulary OMV aims to establish a standard which enables users from academia and industry to identify, find and apply - basically meaning to reuse - ontologies effectively and efficiently. Our demo/poster contribution consists of the presentation of the up-and-running metadata portal ONTHOLOGY (``anthology of ontologies'').

Tiger214 is a small tool to convert Java Tiger (1.5.x) source code to Java 1.4 source code - hence the name 'tiger 2 14'. It exploits a feature of the 1.5-compiler to compile into source code and converts 1.5-generic into the correct 1.4-syntax. After this, some rexexps fine-tune the code to handle autoboxing for-each-loops are not handled at all. Note: you can contribute to the code in a wiki-like manner. Goto to the CVS with username 'wikidev' and pass 'wikidev'. You have full write-rights. You can also check your emails at wikideveloper@gmail.com with the pass 'wikidev123'.

AEON

Thu, 04 Aug 2005 17:52:21 +0200

Did you ever try to evaluate ontologies? Ever tried to apply OntoClean? Did you find it difficult and timeconsuming to tag all the concepts? We have a solution for you.

AEON (Automatic Evaluation of ONtologies) automatically tags concepts with appropriate OntoClean meta-properties. The implementation can be easily expanded to check the concepts for other abstract meta-properties, thus providing for the first time tool support in order to enable intensional ontology evaluation for concepts. Our main idea is using the web as an embodiment of objective world knowledge, where we search for patterns indicating concepts meta-properties. We get an automatic tagging of the ontology, thus reducing costs tremendously. Moreover, AEON lowers the risk of having subjective taggings.

OntoClean is a unique approach towards the formal evaluation of ontologies, as it analyses the intensional content of concepts. Although it is well documented in numerous publications, and its importance is widely acknowledged, it is still used rather infrequently due to the high costs for applying OntoClean, especially on tagging concepts with the correct meta-properties.

We believe that evaluation of Ontologies is important. Therefore we are working on lowering the burden associated with it. AEON is a highly valuable first step.

SEAL - Semantic Portal

Tue, 12 Apr 2005 15:03:37 +0200

SEAL aims to use ontologies as key elements for managing community Web sites and Web portals. The ontology supports queries to multiple sources. It also uses schema information, allowing automatic generation of navigational views (such as navigation hierarchies and mixed ontology and content-based presentation. The core idea behind SEAL is that semantic portals for a community of users contributing and consuming information require Web site management and Web information integration. To reduce engineering and maintenance effort, SEAL uses an ontology for semantic integration of existing data sources and for Web site management and presentation to the outside world. SEAL exploits this ontology to offer mechanisms for acquiring, structuring, and sharing information through semantic annotations between human and machine agents.7 Thus, SEAL combines the advantages of Web site management on the one hand and Web information integration on the other hand.

Ontology Alignment and Mapping

Tue, 26 Oct 2004 14:05:42 +0200

FOAM, Framework for Ontology Alignment and Mapping:

The ontology alignment framework is a tool to full- or semi-automatically align two or more OWL ontologies. It is based on heuristics (similarity) of the individual entities (concepts, relations, and instances). As result we receive pairs of aligned entities. The underlying research has already been presented at different conferences, see e.g.

Happy Aligning.
