Location service information supporting system based on ontology

Ontology-based system for supporting manufacturing sustainability

Sustainability is one of the biggest challenges of this century either for the environment or economical growth. The required cultural shift needs challenging action that will involve deeply software and hardware aspect of manufacturing processes. In this paper, the software part of the matter is addressed by proposing a product centric ontology, in which concepts of product, processes and reso...

Petri Net-Based Ontology Analysis Method for Indoor Location- Based Service System

This paper presents a Petri net based analysis of ontology for indoor location-based services. The proposed method builds up a Petri net model for the given ontology at the first step. Then, it analyzes the Petri net model by running the simulation on it. The proposed method of building a Petri net model for the given ontology is given in the paper. Then algorithms of performing inferences on t...

Supporting Mobile Learning with Location-aware Printing Service Supporting Mobile Learning with Location-aware Printing Service

Learning and studying are very often connected with reading printed materials. In this paper we describe some implementation issues of a common task – printing a document, when applied in a mobile environment. In a non-mobile context this task is simple and is usually taken for granted, but the introduction of a palmtop/laptop equipped with a wireless-LAN card makes the task less trivial. To fu...

Geo-Information (Lake Data) Service Based on Ontology

Recently ontology research has received much attention in geo-information science and the concept of ontology is very important for spatial information concept modeling and data sharing, classification of geographical classes. More importantly, it enriches the semantic theory of spatial information. Geo-information services and geo-information interpretation and extraction are the two main appl...
