SWRL (http://www.w3.org/Submission/SWRL/#2.1) is proposal for a semantic web rules-language, combining sublanguage of the OWL Web Ontology Language (OWL DL and Lite) with those of rule markup language (RuleML). The Rule Markup Language (RuleML) is a markup language developed to express both forward (bottom-up) and backward (top-down) rules in XML for deduction, rewriting, and further inferential-transformational tasks.
SQWRL (Semantic Query-Enhanced Web Rule Language; pronounced squirrel) is a SWRL-based query language that can be used to query OWL ontologies. SQWRL provides SQL-like operations to format knowledge retrieved from an OWL ontology. SQWRL does not alter SWRL’s semantics and uses the standard SWRL presentation syntax supported by the SWRLTab.
Below is the example of SWRL syntax to infer visitor’s location. (more…)

While the command-line
sparql tool is useful for running standalone queries, Java applications can call on Jena’s SPARQL capabilities directly. SPARQL queries are created and executed with Jena via classes in the
com.hp.hpl.jena.query package. Using
QueryFactory is the simplest approach.
QueryFactory has various
create() methods to read a textual query from a file or from a
create() methods return a
Query object, which encapsulates a parsed query. (more…)

Today i attended to Prof. Harold Boley talk in National Chengchi University Taiwan about POSL. I got new knowledge about one of language in semantic web. POSL integrates Prolog’s positional and F-logic’s slotted syntaxes for representing knowledge (fact and rules) in the semantic web. Positional-slotted(POSL) language accomodates various assertional-logical and object-centered modeling styles. (more…)

Suppose i have Event e, which hasStartTime t1 and hasEndTime t2. To calculate the duration using SWRL of the event in minutes i use this rule :
hasStartTime(?e, ?t1) ∧
hasEndTime(?e, ?t2) ∧
temporal:duration(?d, ?t1, ?t2, temporal:Minutes)
→ hasDuration(?e, ?d)
?d is return value in a minute .
