Dragon Systems has continued to develop its continuous speech recognition capability on personal computers, with a strong focus on achieving real-time or near real-time performance in that environment We are now able to run recognition using vocabularies of up to 5000 words, although the larger vocabularies do slow down the recognition substantially; therefore more work still needs to be done t...

This chapter presents an analytical study about methodology and methods to build ontologies and controlled vocabularies, compiled by the analysis of a literature about methodologies for building ontologies and controlled vocabularies and the international standards for software engineering. Through theoretical and empirical research it was possible to build a comparative overview which can help...

Metadata Registries (MDR) are information systems defined to manage and publish metadata related to information and data models. An inherent part of the data models registered within an MDR is the vocabularies used to assign values to data elements. These vocabularies relate to concepts that can be managed by Knowledge Organization Systems (KOS). This paper discusses how an MDR can import and t...

We present a mathematical model of cross-situational learning, in which we quantify the learnability of words and vocabularies. We find that high levels of uncertainty are not an impediment to learning single words or whole vocabulary systems, as long as the level of uncertainty is somewhat lower than the total number of meanings in the system. We further note that even large vocabularies are l...

This paper describes a method of collecting mulitiligual speech data for use in the compilation of spoken command vocabularies for ICT devices and services in the EU, the EFTA countries and Turkey and Russia. The resulting vocabularies will be published as a European standard, for use by industry in the production of such applications. The context of this work is the EU i2010 framework for addr...

Metadata is used to describe documents and applications, improving information seeking and retrieval and its understanding and use. Metadata can be expressed in a wide variety of vocabularies and languages, and can be created and maintained with a variety of tools. Ontology based annotation refers to the process of creating metadata using ontologies as their vocabularies. We present similaritie...

The demo paper presents B-Annot, a Protégé plugin for annotation of ontologies and linked data vocabularies by background model distinctions. In addition, it briefly demonstrates the subsequent use of the annotations created by B-Annot, for verifying the ontological coherence of the ontologies/vocabularies at the level of meta-models. Finally, possible further extensions of the tool and its rol...

Encouragingly accurate translations have recently been obtained using a connectionist translator called RECONTRA (Recurrent Connectionist Translator). In order to deal with tasks of medium or large vocabularies, distributed representations of the lexicons are required in this translator. A simple connectionist model has been recently designed to automatically obtain word distributed representat...

The construction of minimal acyclic deterministic partial nite automata to represent large natural language vocabularies is described. Applications of such automata include: spelling checkers and advisers, multilanguage dictionaries, thesauri, minimal perfect hashing and text compression. Part of this research was supported by a grant awarded by the Brazilian National Council for Scienti c and ...
