As part of preliminary studies for the development of a digital library, we have studied the possibility of using the UMLS Information Sources Map (ISM) database to provide the means to connect and map different terminologies, as well as to facilitate access to available information sources. The main issues discussed are the indexing of and connection to relevant online sources. We found the fe...

1 US president Bill Clinton will hold talks covering arms control, the Russian economy, and the situation in Chechnya during his meeting in Moscow with Russia's new president Vladimir Putin.

In remote sensing, thematic map comparison is often undertaken on a per-pixel basis and based upon measures of classification agreement. Here, the degree of agreement between two thematic maps, and so the difference between the pair, was evaluated through visual and quantitative analyses for two scenarios. Quantitative assessments were based on basic site-specific measures of agreement that are...

This report discusses dimensionality reduction techniques used to create a music map - a map where the distances between songs represent their similarity and that can be used to recommend songs. We evaluate two techniques: Isomap and L-Isomap.

A technique to improve stereoscopic image quality of pictures generated from depth maps is proposed. Generally, there are two key problems with methods that render new images from an original image and its corresponding depth map: the depth map could contain artifacts (e.g., blockiness or contouring) and there is no information on newly exposed (disoccluded) regions. For the former, the solutio...

An aim of WP8 is to develop ‘objective’ components of creativity that could be used to evaluate the creativity of artificial systems and humans. Ideally, the components should form a semantic map with concepts related to the concept of creativity and related to each other. The notion ‘objective’ entails that the sematic map should be derived by objective (i.e., repeatable) methods, instead of c...

When several robots explore the same environment, it is at some point necessary to merge their local maps into a global map to exploit the full potential of the robot team. Efficient multi-robot task coordination is virtually impossible without a common interpretation of the environment. If there is no information available about the relative positioning of the robots or if this information is ...

Localization and mapping are essential capabilities of virtually all mobile robots. These topics have been the focus of a great deal of research, but it is not always easy to tell which methods are best. This paper discusses performance evaluation for an important sub-problem of robot mapping, map optimization. We explore aspects underlying the evaluation of map optimization such as the quality...

Map construction methods automatically produce and/or update road network datasets using vehicle tracking data. Enabled by the ubiquitous generation of geo-referenced tracking data, there has been a recent surge in map construction algorithms coming from different computer science domains. A cross-comparison of the various algorithms is still very rare, since (i) algorithms and constructed maps...
