Purpose – To show that stem generation compares well with lemmatization as a morphological tool for a highly inflectional language for IR purposes in a best‐match retrieval system. Design/methodology/approach – Effects of three different morphological methods – lemmatization, stemming...

Purpose – To present a method for creating a comparable document collection from two document collections in different languages. Design/methodology/approach – The best query keys were extracted from a Finnish source collection (articles of the newspaper Aamulehti ) with the relative average...

Purpose – The aim of this paper is to explore the possibility of retrieving information with Kohonen self‐organising maps, which are known to be effective to group objects according to their similarity or dissimilarity. Design/methodology/approach – After conventional preprocessing, such...

It is generally recognised that numeric databases (NDBs) have become essential in information retrieval (IR). NDBs differ from traditional bibliographic databases (BDBs) with respect to their content, structural complexity, data manipulation capabilities, and the complexity of the user...

This article presents a novel user‐oriented interface for generalised informetric analysis and demonstrates how informetric calculations can easily and declaratively be specified through advanced data modelling techniques. The interface is declarative and at a high level. Therefore it is easy...

Purpose This paper analyses the research in Library and Information Science (LIS) and reports on (1) the status of LIS research in 2015 and (2) on the evolution of LIS research longitudinally from 1965 to 2015. Design/methodology/approach The study employs a quantitative intellectual content...

Purpose The purpose of this paper is to investigate information retrieval (IR) in the context of authentic work tasks (WTs), as compared to traditional experimental IR study designs. Design/methodology/approach The participants were 22 professionals working in municipal administration,...
