Towards Spatio-Temporal Toponym Ontology to Assist in Geographic Information Retrieval

چکیده
During the search for geographical information in web pages, people are geo-referred with toponyms (place names) instead the use of coordinates. The conceptions of places are often complicated ambiguous and different in different time. When gazetteers are utilized as background knowledge in geographic information retrieval (GIR), they are limited because of their poor geographic semantics. Therefore, there is a need to specify the place name to geospatial semantic knowledge. Ontologies play a key role in the development of semantic spatial search. We propose in this paper the design methodology for building the spatio-temporal toponym ontology based on the basic formal ontology (BFO) and the Algerian administrative division. The spatio-temporal toponym ontology includes geographic elements such as spatial relationships, concepts, terms and historical names related to a place, which can assist in GIR by expressing changes and time characteristics of the evolution of place names and providing factual and semantic reports to solving several common problems using free ontology editor tool protégé. Keywords—geographic information retrieval; spatio-temporal ontology; basic formal ontology; place name ontology; Algerian administrative division

Context-aware Modeling for Spatio-temporal Data Transmitted from a Wireless Body Sensor Network
Context-aware systems must be interoperable and work across different platforms at any time and in any place. Context data collected from wireless body area networks (WBAN) may be heterogeneous and imperfect, which makes their design and implementation difficult. In this research, we introduce a model which takes the dynamic nature of a context-aware system into consideration. This model is con...
متن کاملUsing Conceptual and Ontological Models for Tracking Changes of Spatio-Temporal Objects and Concepts over Time
In this paper, we present a new approach that benefits from the advantages of both conceptual and ontological models in order to provide a powerful spatio-temporal data model for geographic information systems (GIS). We base our model on the MADS conceptual model that is transformed to a corresponding ontology model, using database to ontology mapping techniques and a set of transformation rule...
متن کاملToponym Disambiguation Using Ontology-Based Semantic Similarity
We propose a new heuristic for toponym sense disambiguation, to be used when mapping toponyms in text to ontology concepts, using techniques based on semantic similarity measures. We evaluated the proposed approach using a collection of Portuguese news articles from which the geographic entity names were extracted and then manually mapped to concepts in a geospatial ontology covering the territ...
متن کاملAn empirical study of the effects of NLP components on Geographic IR performance
Natural Language Processing (NLP) techniques, such as toponym detection and resolution, are an integral part of most Geographic Information Retrieval (GIR) architectures. Without these components, synonym detection, ambiguity resolution and accurate toponym expansion would not be possible. However, there are many important factors affecting the success of an NLP approach to GIR, including topon...
متن کاملPublic Transport Ontology for Passenger Information Retrieval
Passenger information aims at improving the user-friendliness of public transport systems while influencing passenger route choices to satisfy transit user’s travel requirements. The integration of transit information from multiple agencies is a major challenge in implementation of multi-modal passenger information systems. The problem of information sharing is further compounded by the multi-l...
