Event order generation using Reference Event based qualitative Temporal (REseT) relations in Time Event Ontology

Time ontology with Reference Event based Temporal Relations (RETR)

Ontology of time is gaining importance as it is necessary to realize the Semantic Web. They play an important role in Natural Language Processing applications, data mining, decision support systems etc. Existing time ontologies have been represented using DAML, OWL, KSL, KIF and Cyc. In time ontology, events are concepts and topological temporal relations between events are either Point based o...

Temporal Pattern Mining and Reasoning using Reference Event based Temporal Relations (RETR)

Reasoning and mining over temporal patterns has to be more specific and accurate for efficient knowledge discovery. The patterns expressed with the temporal interval relationships of Allen have the problem of aggregating many events under one relation “before” and hence leads to ambiguity. In this work an attempt has been made to overcome this by augmenting the “before” relation with four conte...

Log-based Generation of Event Labels using Event Attributes

A prompt increase in the number of sensor devices, and the progress in sensor data analytics have led to new opportunities as well as challenges. One such challenge is to acquire and analyze life-log data of human activities. The evolution of ubiquitous computing environments and devices has facilitated the recognition of the life-log concept, which addresses the tracking of behavioral data wit...
