Rule Modeling Using Semantic MediaWiki

Semantic MediaWiki (SMW) is a popular semantic wiki engine that enables collective knowledge modeling within the expressivity of a small subset of OWL. However, SMW is limited in offering native support for modeling rules. In this paper, we show that by using templates and semantic queries provided by SMW, it is possible to model several types of rules within SMW, e.g., OWL entailment rules and logic programs. Such modeling practice enables us to perform some broadly useful inference tasks on SMW, e.g., integrity constraint checking

A Controlled Natural Language Interface for Semantic Media Wiki

Despite their potential value as collaborative knowledge editing systems, semantic wikis present a number of usability challenges for human end users. In particular, there are several mismatches between the simple user interaction mechanisms of wikis (which are the key to the success of wikis) and the need for users to create, edit and understand structured knowledge content (e.g., in the form of RDF or OWL ontologies). In this paper, we present a Controlled Natural Language (CNL) approach to collaborative ontology development using Semantic MediaWiki (SMW). In order to support the expressivity required for OWL ontology development, we extended the representational substructure of the SMW system with an OWL meta model using a template-based mechanism. To improve usability, we provided a form-based guided input interface and implemented several CNL verbalizers (CNL text generation components). In particular, we developed verbalizers for the English and Chinese variants of the Rabbit CNL, as well as the Attempto Controlled English (ACE) CNL. The combination of semantic wiki systems and CNL editing interfaces may provide an effective mechanism for promoting the large-scale collaborative creation of semantically-enriched online content

Star formation in the large Magellanic cloud

What role the Large Magellanic Cloud (LMC), a dwarf irregular galaxy, plays in understanding infrared luminous galaxies is discussed. There are two main reasons the LMC may prove helpful. One, the LMC is only 55 kpc away, very nearby compared to much rarer high luminosity systems. Second, the environment in the LMC is distinctly different than in the Milky Way, at least those parts of the Milky Way interior to the sun, where most of the studies of massive star formation were concentrated. The LMC is an interacting system with a large amount of neutral hydrogen that is pushed around by the galaxy's encounter with the Milky Way. Perhaps a good understanding of star formation process in the LMC will provide guidance in the study of the infrared luminous galaxies. Two questions which will be addressed are: how is star formation in the LMC similar to the Milky Way Galaxy, and how is it different

GIDS: Global Interlinked Data Store

This paper introduces the Global Interlinked Data Store1 (GIDS), a technique to support the easy creation and retrieval of interlinked semantic data within a web-scale distributed network environment such as the World Wide Web (WWW). The GIDS enables the network to be treated as a data store without worrying about files, databases or other traditional data storage concerns. Data created on the network can be subsequently accessed and navigated by end users and software agents alike. The GIDS proposes a novel three-stage data storage process which enables the data to be stored in up to three contextually relevant locations to enhance subsequent retrieval opportunities. We believe that the capability offered by the GIDS will be of significant use to rapidly formed diverse coalitions who wish to communicate and exchange semantic data in a large network environment such as the WWW
