This paper describes a proposed new syntax that can be used to write and read OWL ontologies in Controlled Natural Language (CNL): a well-defined subset of the English language. Following the lead of Manchester OWL Syntax in making OWL more accessible for non-logicians, and building on the previous success of Schwitter's PENG (Processable English), the(More)
At OWLED2007 a task force was formed to work towards a common Controlled Natural Language Syntax for OWL 1.1. In this paper members of the task force compare three controlled natural languages (CNLs) — Attempto Controlled English (ACE), Ordnance Survey Rabbit (Rabbit), and Sydney OWL Syntax (SOS) — that have been designed to express the logical content of(More)
Situation Awareness (SA) is the problem of comprehending elements of an environment within a volume of time and space. It is a crucial factor in decision-making in dynamic environments. Current SA systems support the collection , filtering and presentation of data from different sources very well, and typically also support some form of low-level data(More)
This study includes developing a suitable ontology to represent a simple domain using an ontology editor, representing logical constraints using constructs available within OWL-DL, and then illustrating that some of the classification criteria set for the task cannot be represented within OWL and require logical rules to be added using a rule language to(More)
A significant boost on the path towards a web of linked, open data is the establishment and promotion of common semantic resources including ontologies and other operationalised vocabularies, and their instance data. Without consensus on these, we are hamstrung by the famous " n-squared " mapping problem. In addition, each vocabulary has its own associated(More)
The Semantic Web brings powerful languages for creating models, based on Description Logics and Rules. These languages are used within ontology engineering tools and applied in strong and efficient reasoners. Working within the context of a Summer School, we explored these technologies by creating a small and easy to understand example, working firstly with(More)
Both ISO's Topic Map Standards and the W3C's Semantic Web Recommendations provide the means to construct meta-level semantic maps describing relationships between information resources. Developed independently, attempts at interoperability between the original Topic Map standard and RDF have proved challenging. However, ISO 13250's drafting of an explicit(More)
aBstract Semantic technologies are a new wave of computing, using explicit representation of meaning to enable data interoperability and more powerful and flexible information services and transactions. At the core of semantic technologies are ontologies, which capture meaning explicitly and may be used to manipulate and reason over information via its(More)
