twinkle-sparql-tools

Twinkle is a simple GUI interface that wraps the ARQ SPARQL query engine. The tool should be useful both for people wanting to learn the SPARQL query language, as well as those doing Semantic Web development.

usdis

(New! Sep. 27, 2008) Some materials illustrating the work have be uploaded and labled as 4.1 through 4.5. They include: 2 conference papers, a presentation ppt accompanying the papers, and 2 video clips that demonstrate the usage of the two clients. USDIS(Uniform Semantic Data Integration ... [More] System) is a Java project origigating from our research work in Semantic Web & Web Serivces. It's a dynamic data integration system, which integrates both RDF data sources and information-providing Web Services. At runtime the queries posed by the user against the domain ontology result in dynamic invocations of the matched Web Services as well as evaluation of SPARQL queries on RDF datasets. A successful experiment on the public Amazon E-Commerce Service has shown the great usability and generality of the system. The arctecture of the system is : There are 2 runnable classes at present: cn.edu.bupt.usdis.ui.DataQueryClient cn.edu.bupt.usdis.ui.DataSourceMgmtClient The former is to perform data query. And the latter is to create semantic description (i.e. Uniform Query) of a Data Source and bind it with underlying Web Services or SPARQL endpoint(at present only single local RDF file is supported). They both have a GUI. As a demo facility, there is a naive travel&book ontology and 2 data sources contained in the distribute package. The data source No.4 is the Amazon book search "data source" which can result in a real time Amazon Web Service call to search books by topic. Try it from DataQueryClient and enjoy it! A snapshot of the data query formulation GUI: A snapshot of the Web Service annotation GUI - on the ItemSearch operation of Amazon E-Commerce Service (ECS): Note the array index in the expression for element path used here can take 2 special values: '*' is used to allow the Web Service to return multiple records which is a common case in data query. Certainly there are at most one '*' appeared in an element and its position - notated as "fork point" - must be same in all elements which have a fork point. ".." is allowed to be appeared in an array that is at the right-most node of an element path, which is to indicate the concatenation of all members of that array (separated by ", "). In all other cases, only '0' is permitted for simplicity. A snapshot of result to the query - “list books about ‘Semantic Web’ and published since 2006”. Note the results come from both the Amazon Web Service and a local RDF dataset. You see the data is really Integrated! In backend and background, the data flow inside USDIS, especially the procedure of registering a Web Service and the mechanism of dynamic invocation of Web Services, is shown below: Copyright 2008 BUPT [Less]

dftproject

The Distributed Family Tree is an open network of genealogical data and metadata. In a nutshell, the big idea is that we can combine all available genealogical information on the Internet into a single distributed network. Genesis, the current focus of this effort, is a software research ... [More] assistant based on the Eclipse RCP. It provides basic data storage and retrieval, user interface, and software agent coordination facilities. It can be extended with plugins to access new data sources, analyze and correlate genealogical facts, provide new views on the data, and much, much more. Additional information can be found at the project home. [Less]

kipler

Kipler is an object-oriented tableau framework for rapid development of (modalized) description logic reasoners.It also comes with readily implemented decision procedures for some of these logics. A decision procedure for such a logic can be implemented by (programmatically) extending the classes ... [More] provided by Kipler and thus making use of object-oriented programming techniques. It is not our aim to develop a general tableau definition language for these logics. Kipler is under heavy development. Currently it supports SHIQ ABox reasoning and experimental SHOIQ reasoning. These logics are the underlying formalism of Web Ontology Language: OWL and thus are included in Kipler's profile to demonstrate its capabilities. These implementations also employ some optimization techniques, e.g., semantic branching and backjumping, to make them "practical". The facilities provided by Kipler for optimizations can be extended to modal description logics as well. The first alpha version is planned to be released when integration with an OWL parsing API is completed and more tests are done. The name Kipler means "modalities" in Turkish. [Less]
