INTRODUCTION In this paper, we describe the system used by the UMIST team as members of the FACILE consortium, to undertake the NE task in MUC-7. The main characteristics of this system employed are as follows: it is rule-based its rule formalism supports context-sensitive partial parsing rules may use pattern-matching-style iteration operators the notation(More)
We report on the design and partial implementation of a bilingual English-Arabic dictionary based on WordNet. A relational database is employed to store the lexical and conceptual relations, giving the database extensibility in either language. The data model is extended beyond an Arabic replication of the word↔sense relation to include the morphological(More)
Corpus-based methods have been widely used to tackle NLP tasks after the advent of annotated corpora with a notable success. Inevitably, shifting from classical rule-based to corpus-based method has a major drawback. That is, most of corpus-based ones produce statistical models that are hard to interpret and modify along with their higher complexity in(More)
Members of the aldehyde dehydrogenase gene (ALDH) superfamily play an important role in the enzymic detoxification of endogenous and exogenous aldehydes and in the formation of molecules that are important in cellular processes, like retinoic acid, betaine and gamma-aminobutyric acid. ALDHs exhibit additional, non-enzymic functions, including the capacity(More)
UK PubMed Central (UKPMC) is a full-text article database that extends the functionality of the original PubMed Central (PMC) repository. The UKPMC project was launched as the first 'mirror' site to PMC, which in analogy to the International Nucleotide Sequence Database Collaboration, aims to provide international preservation of the open and free-access(More)
Text Mining is a relatively new area of research, very interesting for both computational linguists and data miners. It involves collecting and analyzing quantities of textual data by domain experts, whose main task is the manual revision of markup. We describe a suite of tools used to simplify the process: the Parmenides System that consists of data(More)
The website www.aldh.org is a publicly available database for nomenclature and functional and molecular sequence information for members of the aldehyde dehydrogenase (ALDH) gene superfamily for animals, plants, fungi and bacteria. The site has organised gene-specific records. It provides synopses of ALDH gene records, marries trivial terms to correct(More)
Curation of biomedical literature is often supported by the automatic analysis of textual content that generally involves a sequence of individual processing components. Text mining (TM) has been used to enhance the process of manual biocuration, but has been focused on specific databases and tasks rather than an environment integrating TM tools into the(More)
OBJECTIVE The human aldehyde dehydrogenase (ALDH) gene superfamily consists of 19 genes encoding enzymes critical for NAD(P)-dependent oxidation of endogenous and exogenous aldehydes, including drugs and environmental toxicants. Mutations in ALDH genes are the molecular basis of several disease states (e.g. Sjögren-Larsson syndrome, pyridoxine-dependent(More)
The refracton hypothesis describes the lens and cornea together as a functional unit that provides the proper ocular transparent and refractive properties for the basis of normal vision. Similarities between the lens and corneal crystallins also suggest that both elements of the refracton may also contribute to the antioxidant defenses of the entire eye.(More)
