Wide-Coverage Semantics for Spatio-Temporal Reasoning
نویسنده
چکیده
In this article, we describe our research on wide-coverage semantics for Frenchlanguage texts and on its application to produce detailed semantic descriptions of itineraries. Using a categorial grammar semi-automatically extracted from the French Treebank and a manually constructed semantic lexicon, the resulting parser computes discourse representation structures representing the meaning of arbitrary text. The main goal of this paper is to apply and specialize this general framework of wide-coverage semantics to the spatial and temporal organization of the Itipy corpus — a set of 19th century texts discussing voyages through the Pyrenees mountains. The implemented system gives satisfying results and opens the door to the integration with specialized extensions, such as a separate module computing the discourse relations between the textual units. RÉSUMÉ. Dans cet article, nous donnons une description de notre recherche sur la sémantique à large couverture pour le français et, plus précisément, de la façon dont ces expressions sémantiques sont utilisées pour donner l’interprétation spatio-temporelle des itinéraires. En utilisant une grammaire catégorielle extraite semi-automatiquement du French Treebank et un lexique sémantique construit manuellement, l’analyseur convertit les analyses syntaxiques en DRS (discourse representation structures). Le but principal de cet article est l’application et la spécialisation de cette méthodologie générale au corpus Itipy contenant des récits de voyage du 19e siècle. La chaîne de traitement complète donne des résultats tout à fait satisfaisants et laisse l’opportunité d’y ajouter des extensions spécialisées, comme un composant qui calculerait les relations discursives entre les parties du texte.

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 کاملTowards a generalized spatio-temporal understanding for the semantic web
While there have been decades of research on spatio-temporal reasoning (STR) logics, the obstacle preventing a complete understanding of our world is the lack of spatio-temporal structures in existing ontologies. This is particularly true for semantic web efforts: for how do we begin to create a semantic web when we cannot define the semantics of the entities with which we which we wish to popu...
متن کاملA Qualitative Representation of Evolving Spatial Entities in Two-dimensional Topological Spaces
This paper identifies a spatio-temporal model that represents the evolution of 2-dimensional spatial entities. The research proposes a qualitative reasoning approach for modelling time in Geographical Information Systems (GIS). Spatio-temporal relationships are inferred by combining properties of measured time (chronological sequences) and historical time (ordered events) to geometrical and top...
متن کاملBayesian Learning on Graphs for Reasoning on Image Time-series
Satellite image time-series (SITS) are multidimensional signals of high complexity. Their main characteristics are spatio-temporal patterns which describes the scene dynamics. The information contained in SITS was coded using Bayesian methods, resulting in a graph representation [2]. This paper further presents a concept of interactive learning for semantic labeling of spatio-temporal patterns ...
متن کاملDeveloping an Object-Oriented Video Database System with Spatio-Temporal Reasoning Capabilities
Video data management (VDM) is fast becoming one of seminar topics in multimedia information systems. In VDM systems, there exists an important need for novel techniques and mechanisms which can provide an efficient retrieval facility of the voluminous data stored in the databases. While "content-based" retrieval provides a direct and an intuitive approach for video data access, it is inadequat...
