This article describes automated tools for increasing organizational awareness within a global enterprise. The MITRE Corporation is the context for the current work, however the tools and techniques are general and should apply to a wide variety of distributed, heterogeneous organizations. These tools provide awareness of team members and materials in virtual collaboration environments as well ...

Link discovery is a new challenge in data mining whose primary concerns are to identify strong links and discover hidden relationships among entities and organizations based on low-level, incomplete and noisy evidence data. To address this challenge, we are developing a hybrid link discovery system called KOJAK that combines state-of-theart knowledge representation and reasoning (KR&R) technolo...

Providing an adequate route description requires in-depth spatial knowledge of the route in question. In this article we demonstrate that despite having travelled a route recently and having much experience of the area in question, an individual may lack such a degree of knowledge. Previous research and experience informs us that a map is an effective tool for bridging gaps in one’s spatial kno...

Introduction Model finding technology is highly useful in nearly every stage of logico-mathematical discovery. In the initial formalization of domain knowledge, model finders may be employed to ensure that formulae intended to capture some real domain knowledge are not contradictory; in conjecture generation and verification, the presence or absence of certain models can indicate whether or not...

Organisations are increasingly information intensive; hence providing access to data that is trapped in various proprietary forms including catalogues, databases, human resource systems and internally generated documents is now becoming a significant and challenging task. The authors have undertaken research into approaches to capture relevant knowledge from legacy documents. This is achieved b...

Organisations capitalise on their best knowledge through the improvement of shared expertise which leads to a higher level of productivity and competency. The recognition of the need to foster the sharing of expertise has led to the development of expert finder systems that hold pointers to experts who posses specific knowledge in organisations. This paper discusses an approach to locating an e...

Today, great observatories around the world, devote a substantial amount of observing time to sky surveys. The resulted images are inputs of source finder modules. These modules search for the target objects and provide us with source catalogues. We sought to quantify the ability of detection tools in recovering faint galaxies regularly encountered in deep surveys. Our approach was based on com...

However, since this model is acteristics, the reflectance parameters can be esticomplicated in nature, the simplified...
