In this thesis, we have proposed ACTOM, a Topic Map building approach based on an automated processtaking into account multilingual documents and Topic Map evolution according to content and usage changes.To enrich the Topic Map, we are based on a domain thesaurus and we propose to explore all potentialquestions related to source documents on order to represent usage in the Topic Ma...

The tropical root weevil, Diaprepes abbreviatus (L.), has been a pest of citrus and ornamental plants since its introduction into Lake County, FL, in 1964. Since then, it has colonized the Florida peninsula to the south of its point of introduction but has not expanded its range to the north. A lower threshold for oviposition by D. abbreviatus was estimated as 14.9 degrees C. Eggs were highly s...

Many documents and more generally many resources are produced or used in an e-learning application. In order to capitalize these resources and to facilitate their access, we propose to organise them in a “learning organisational memory” (MEMORAe project). In this paper, we present the context of use, the needs and the contents of this memory. We describe the ontologies and the Topic Maps formal...

Nowadays, data handled by an institution or company is spread out by more than one database and lots of documents of different types. To extract the information implicit in that data, it is necessary to pick parts from those various archives. To obtain a general overview, those information slices should be gather. Different approaches can be followed to achieve that integration, ranging from th...

Synthetic aperture radar (SAR) yields high resolution two dimensional images of the radar backscatter properties of the sea surface and can thus be used to measure wind field and sea state from space independent of daylight and cloud coverage. This makes SAR particularly suited to investigate severe weather events over the oceans. ERS SAR wave mode is acquired over the ocean every 200 km along ...

Road traffic safety is the result of a complex interaction of factors, and causes behind road vehicle crashes require different measures to reduce their impacts. This study assesses how strongly the variation in daily winter crash rates associates with weather conditions in Finland. This is done by illustrating trends and spatiotemporal variation in the crash rates, by showing how a GIS applica...

This paper describes the digitization and utilization of Complete Map of Peking, Qianlong Period, which is the oldest measured map of Beijing made about 250 years ago. We first proposed the geometric correction method called “linepreserving distance weighting method” to preserve linear features relevant in the old map of cities. Next we improved the reliability of the old map as information inf...

In E-Learning, the selection of the pedagogical contents to teach and the organization of this content are two principal operations during the design of a course. The growth and the diversity of the informational resources used generate problems of diffusion, access, of classification and management. With the MEMORAe project, we deal with these problems and propose to answer them by using an on...

This paper explores the idea of using contexts to support more efficient information search in Topic Maps-based digital libraries. The notion of context is perceived as abstraction of grouping of domain concepts and resources based on the existing semantic relationships between them. The proposed model of context is used for context representation in the TM4L environment.
