Understanding the semantic relations between terms in specialized texts is of critical importance in translation and terminology, and generally speaking in learning from texts. Our research highlights the advantages of formalizing them in order to build hierarchies and sets of horizontal conceptual relations (i.e. process-oriented relations) for knowledge acquisition. This paper discusses a method for extracting domain-specific semantic relations in specialized texts. Obviously, some texts are more appropriate than others in this regard. ‘Knowledge-rich’ texts such as encyclopaedia and textbooks are considered good materials because of the density and richness of thematic information. Considering them as such, we used the encyclopaedic articles of the Dictionnaire analytique de la distribution/Analytical Dictionary of Retailing. We retrieved over 3000 terms semantically related to all 350 headwords of the Dictionary, and grouped them into 28 classes of relations (paradigmatic, i.e. generic, specific, agent, goal, instrument, recipient, location, etc., and also syntagmatic, such as related verbs and adjectives). This paper discusses in particular the generic, agent and property relations and examines the linguistic markers that permit their retrieval.

Abstract. In this paper, we propose a methodology for designing data lake dedicated to Spatial Data and an implementation of this specific framework. Inspired from previous proposals on general data lake Design and based on the Geographic information – Metadata normalization (ISO 19115), the contribution presented in this paper integrates, with the same philosophy, the spatial and thematic dimensions of heterogeneous data (remote sensing images, textual documents and sensor data, etc). To support our proposal, the process has been implemented in a real data project in collaboration with Montpellier Métropole Méditerranée (3M), a metropolis in the South of France. This framework offers a uniform management of the spatial and thematic information embedded in the elements of the data lake.

The article is devoted to the consideration and generalization of modern management capabilities and tools of distributed social communities formed based on online resources (social networks) to achieve the set socio-economic management goals. The authors conducted a problem analysis of the identified opportunities for managing specialized social thematic resources in the implementation of joint projects, the formation of social groups based on interests and hobbies, and the promotion of brands and products. The authors identify software tools for managing social network media resources. These tools allow collecting data on consumer interaction (b2c), monitoring thematic information, and attracting a new target audience.

Geographical applications in EIA studies is appropriate to build up and extend their knowledge and skills in using Geographic Information Systems (GIS) in Environmental Impact Assessments (EIA), and obtain practical experience in the application of GIS technologies and disciplines. This article highlights emerging topics related to the principles and practice of EIA, including concepts, tools and methods, and related issues. GIS as a tool will be used to visually illustrate the implications of spatial decisions. GIS is applied in all EIA stages: from the acquisition, storage and display of thematic information relative to the vulnerability of the affected resources, to impact prediction and qualification, evaluation, and finally, presentation. This paper highlights how GIS applications using in EIA process in different countries and find out possibility to incorporate those applications in EIA studies in Nepal.Hydro Nepal: Journal of  Water, Energy and Environment, Issue 4 2009 pp.21-23

SPOT HRV images were evaluated for their content of thematic information in relation to specific geographical features required for 1:50 000 scale topographic maps. Information was extracted by visual methods from multispectral and panchromatic image transparencies using the PROCOM-2 system. Mapping experiments were carried out on the Sherbrooke, Quebec, test area by experienced interpreters who had limited background knowledge of the area. Excellent feature detection and identification were achieved with SPOT images, especially for linear cultural features (e.g., road, railway). Limitations to mapping related mostly to very small area or point form features (e.g., building, tower, junkyard). Results improve when both multispectral and panchromatic images are used for interpretation. BULK corrected images are very suitable for quick and accurate visual mapping. Stereo-analysis is not essential, but provides a good supplement to mapping. We conclude that SPOT images have a most encouraging potential for topographic mapping, particularly if supported by appropriate field verification.

Abstract. Map is an effective communication means. It carries and transmits spatial information about spatial objects and phenomena, from map makers to map users. Therefore, cartography can be regarded as a communication system. Efforts has been made on the application of Shannon Information theory developed in digital communication to cartography to establish an information theory of cartography, or simply cartographic information theory (or map information theory). There was a boom during the period from later 1960s to early 1980s. Since later 1980s, researcher have almost given up the dream of establishing the information theory of cartography because they met a bottleneck problem. That is, Shannon entropy is only able to characterize the statistical information of map symbols but not capable of characterizing the spatial configuration (patterns) of map symbols. Fortunately, break-through has been made, i.e. the building of entropy models for metric and thematic information as well as a feasible computational model for Boltzmann entropy. This paper will review the evolutional processes, examine the bottleneck problems and the solutions, and finally propose a framework for the information theory of cartography. It is expected that such a theory will become the most fundamental theory of cartography in the big data era.
