A Novel Combined Term Suggestion Service for DomainSpecific Digital Libraries

by Daniel Hienert, Johann Schaible - Research and Advanced Technology for Digital Libraries , 2011
"... Abstract. Interactive query expansion can assist users during their query formulation process. We conducted a user study with over 4,000 unique visitors and four different design approaches for a search term suggestion service. As a basis for our evaluation we have implemented services which use thr ..."

three different vocabularies: (1) user search terms, (2) terms from a terminology service and (3) thesaurus terms. Additionally, we have created a new combined service which utilizes thesaurus term and terms from a domain-specific search term recommender. Our results show that the thesaurus-based method

Lexical Substitution for the Medical Domain

by Martin Riedl, Michael R. Glass, Alfio Gliozzo
"... In this paper we examine the lexical substitu-tion task for the medical domain. We adapt the current best system from the open domain, which trains a single classifier for all instances using delexicalized features. We show sig-nificant improvements over a strong baseline coming from a distributiona ..."

Adaptive string similarity metrics for biomedical reference resolution

by Ben Wellner - In Proceedings of BioLink 2005 , 2005
"... In this paper we present the evaluation of a set of string similarity metrics used to resolve the mapping from strings to concepts in the UMLS MetaThesaurus. String similarity is conceived as a single component in a full Reference Resolution System that would resolve such a mapping. Given this quali ..."

We use an Arabic corpus to extract domain knowledge represented by topic related concepts/ keywords and the lexical relations among them. The user’s query is expanded once by using

Automatic Ontology Extraction from Unstructured Texts

by Khurshid Ahmad, Lee Gillam - In R. Meersman and Z. Tari (eds) On the Move to Meaningful Internet Systems - ODBASE 2005 , 2005
"... Abstract. Construction of the ontology of a specific domain currently relies on the intuition of a knowledge engineer, and the typical output is a thesaurus of terms, each of which is expected to denote a concept. Ontological ‘engineers’ tend to hand-craft these thesauri on an ad-hoc basis and on a ..."

Probabilistic Lexical Generalization for French Dependency Parsing

by Enrique Henestroza Anguiano, Marie C
"... This paper investigates the impact on French dependency parsing of lexical generalization methods beyond lemmatization and morphological analysis. A distributional thesaurus is created from a large text corpus and used for distributional clustering and WordNet automatic sense ranking. The standard a ..."

Abstract HYKIS- An Information Retrieval System based on a Hybrid Knowledge base*

by Dongwook Shin, Hyongmuk Lim, Yongun Yoon, Keysun Choi
"... This paper aims at developing a knowledge-based infor-mation retrieval system that allows a naive user to re-trieve relevant documents effectively, without any help of a domain expert. For this, it develops a hybrid knowl-edge base that lets most of heuristics be represented in a simple and structur ..."

As knowledge is usually categorized by domain independent and domain dependent one, it separates the store of the knowledge into two bases: domain independent knowledge base (Ibase) and domain dependent knowledge base (Dbase). Ibase is used as a graph-based thesaurus that permits “ is
