Named-entity recognition involves the identification and classification of named entities in text. This is an important subtask in most language engineering applications, in particular information extraction, where different types of named entity are associated with specific roles in events. The manual construction of rules for the recognition of named(More)
This paper presents a large-scale Greek morphological lexicon, developed by the Software & Knowledge Engineering Laboratory (SKEL) of NCSR "Demokritos". The paper describes the lexicon architecture, the procedure followed to develop it, as well as the provided functionalities to update it. The morphological lexicon was used to develop a lemmatiser and a(More)

for dissemination) This document outlines the “Methodology for Semantics Extraction from Multimedia Content” that will be followed in the framework of the BOEMIE project. The basic aim is to describe the architecture and methods that will be used in each particular modality (text, image, video-audio) for extracting semantics from multimedia content using an(More)
This paper addresses the problem of Information Extraction (IE) system customization to new domains and extraction needs with the use of PatEdit, an IE Pattern Editor. PatEdit is a human-assisted knowledge engineering tool, that facilitates the production of IE patterns. First, we present the problem of IE system customisation and the use of human assisted(More)
for dissemination) This document specifies the general architecture of the BOEMIE prototype system. It elaborates on the specification approach used for the architecture, on suitable modeling techniques, technical plat­ forms and integration aspects.
