Virtual Schemas are part of the visual information retrieval system called Mavigator. The system is dedicated to naive users (computer non-professionals) and allows them to retrieve information from any data source, in particular, from objectoriented and XML-oriented databases. A significant problem related to all browsing tools is a way of presenting database schema graph. In many cases, there...

Reformatting information currently held in databases into HyperText Markup Language (HTML) pages suitable for the World-Wide Web (WWW) requires significant effort both in creating the pages initially and their subsequent maintenance. We avoid these costs by directly coupling a WWW server to the source data within a database using additional software we have developed. This software layer automa...

In our paper we introduce comprehensive solution for processing and archiving information about artwork specimens used in the course of art restoration – Nephele. The information processing based on image data is used in the procedure of identification of pigment and binder present in the artwork, which is very important issue for restorers. Proposed approach geometrically aligns images of micr...

The development of spectrum measurement infrastructure that can produce real-time geographic maps of spectrum usage is important to the deployment of future wireless systems. Such an infrastructure also provides the basis for creating a spectrum database in support of dynamic spectrum access. We are developing algorithms that can aggregate, classify and geographically map collected RF power mea...

We describe the design of an object-oriented multimedia database management system that can store and manage SGML/HyTime compliant multimedia documents. The system is capable of storing, within one database, different types o f documents by accommodating multiple document type definitions (DTDs). This is accomplished by dynamically creating object types according to element definitions in each ...

1 Abstract We present work in progress on creating and using a novel audiovisual database that contains a diverse set of conversational expressions. The database is currently undergoing cleaning, annotation and validation to make it useful for the research community. While our main focus is on conversational expressions, we believe that the audio data is of use for the language community. We ai...

Commentaries by Derrfuss and Mar (Derrfuss, J., Mar, R., 2009. Lost in localization: the need for a universal coordinate database. Neuroimage.) and Nielsen (Nielsen, F.A., 2009. Lost in localization: a solution with neuroinformatics 2.0? Neuroimage.) outline the need for a universal coordinate database and some possible approaches to creating one. I highlight the issue of minimal or maximal dat...

Diphone Backoff mechanisms in text-to-speech provide a means of ensuring that synthesis of the text takes place, even if some of the diphones in the text are missing in the speech database. This paper describes an automatic method for synthetically creating missing diphones from halfphones that are in the speech database.

This paper explores the linguistic and technical challenges in creating a typological database for demonstrative and personal pronouns. Our database identifies a fundamental difference between morphological (or semantic) features that are relatively fixed across languages and those that are highly variable from one language to the next.
