Re: real world use cases for temporal reasoning on the Semantic Web

Chuming:

At the HCLS interest group, the "adaptable clinical protocols and 
pathways" group attempts to deal with temporal concepts.  There are four 
types of temporal constraints seen in clinical guidelines and protocols. 
Please see wiki page 
(http://esw.w3.org/topic/HCLS/ACPPTaskForce/TimeConceptUseCase". 

Our goal is for the reasoner to make real-time recommendations to a 
patient.  So the reasoner needs to know a reference to the real-time of 
the patient encounter event. 

We did some experiments on modelling these four types of temporal patterns 
(i.e. elapse time, duration, frequency, repetition)  using a rdf:List to 
simulate a range concept like (start  end).  Then we write rules (in N3) 
to tell the reasoner how this range (list) should be handled.  This, of 
course, is not what transitionally the "temporal reasoning on the Semantic 
web".  Yet it is a simple mechanism to do the reasoning about temporal 
concepts on the semantic web :).

Kind regards.

real world use cases for temporal reasoning on the Semantic Web








Dear All,

Sorry for cross posting.

Does anybody have some use cases which require temporal reasoning in the 
context of Semantic Web? In the domain of e-business and e-life science, 
many of the activities and knowledge are event-based. The temporal 
reasoning would be an important part of a Semantic Web based application.

Any pointers to those kind of use cases or the related work will be 
highly appreciated.

Thanks,

Chuming Chen
