Information Retrieval systems are limited by the linguistic variation of language. ... Two different sources of syntactic information, queries and documents, are studied in order to increase the performance of Information Retrieval systems. ... In this paper we study how the use of syntactic information can improve the performance of Information Retrieval systems, analyzing the performance of different approaches for managing the syntactic variation ...doi:10.1145/1096601.1096643 dblp:conf/doceng/VilaresGA05 fatcat:z6khtwza25ca3pqnhayivefyau

This article describes the application of lemmatization and shallow parsing as a linguistically-based alternative to stemming in Text Retrieval, with the aim of managing linguistic variation at both word ... Several alternatives for selecting the index terms among the syntactic dependencies detected by the parser are evaluated. ... Conclusions Throughout this article we have studied the employment of Natural Language Processing techniques in Text Retrieval as an alternative to stemming for managing linguistic variation. ...doi:10.1007/978-3-540-30075-5_36 fatcat:b6xn6age4rfflainp2flj6qlqi

next step consists of deciding how to process, at phrase level, its syntactic content in order to manage the syntactic variation of the document. ... The first approach is based on the lemmatization of the text in order to avoid inflectional variation. ...

Text mining techniques, which involve the processes of information retrieval, information extraction and data mining, provide a means of solving this. ... With biomedical literature increasing at a rate of several thousand papers per week, it is impossible to keep abreast of all developments; therefore, automated means to manage the information overload ... Review TRENDS in Biotechnology Vol.24 No.12 Syntactic variations characterize the different realizations of a predicate (verb); thus, for the verb 'activate', we can have several syntactic variations ...doi:10.1016/j.tibtech.2006.10.002 pmid:17045684 fatcat:ppkcfka7yrenjkz3z3ad4dj6ha

In this paper we describe Tagged Information Management System (TIMS), an integrated knowledge management system for the domain of molecular biology and biomedicine, in which terminology-driven literature ... Tag-based interval operations and a query language are introduced in order to facilitate KA and retrieval from XML documents. ... The main goal of literature mining is to retrieve knowledge that is 'buried' in a text and to present the distilled knowledge to users in a concise form. ...doi:10.1016/s1386-5056(02)00055-2 pmid:12460630 fatcat:yulxesw4svffxcnzhx5i5n6ayy
Final results are evaluated for precision and recall, and implications for indexing and retrieval are discussed. ... This includes a finite-state part of speech tagger, a derivational morphological processor for analysis and generation, and a unificationbased shallow-level parser using transformational rules over syntactic ... In using a list of controlled terms coupled with a syntactic analyzer, the method is more precise than traditional text simplification methods. ...doi:10.3115/976909.979621 dblp:conf/acl/JacqueminKT97 fatcat:ij2a6wxg7fdtfm7pdagrmas4ga

Reports results of a market study to determine the changes that have taken place in text retrieval and imaging systems: the 2 dominant components of electronic document management systems (EDMS). ...
In this respect, we introduce the phrase retrieval hypothesis to replace the keyword retrieval hypothesis. ... AbstractÐIn this article we describe a retrieval schema which goes beyond the classical information retrieval keyword hypothesis and takes into account also linguistic variation. ... Word sense disambiguation tries to deal in a degree with semantical variation. The problem of cooccurrence brings the use of syntactic information into retrieval. ...doi:10.1016/s0306-4573(98)00030-2 fatcat:xvp3dr56enh2hdz7lsa6lj6ti4
The performance of Information Retrieval systems is limited by the linguistic variation present in natural language texts. ... We propose the use of syntactic dependencies as complex index terms in an attempt to solve the problems deriving from both syntactic and morpho-syntactic variation and, in this way, to obtain more precise ...
