Observing users, designing clarity: A case study on the user‐centered design of a cross‐language information retrieval system

Abstract

This report presents a case study of the development of an interface for a novel and complex form of document retrieval: searching for texts written in foreign languages based on native language queries. Although the underlying technology for achieving such a search is relatively well understood, the appropriate interface design is not. A study involving users from the beginning of the design process is described, and it covers initial examination of user needs and tasks, preliminary design and testing of interface components, building, testing, and refining the interface, and, finally, conducting usability tests of the system. Lessons are learned at every stage of the process, leading to a much more informed view of how such an interface should be built.

Analysing user's queries for cross‐language image retrieval from digital library collections

“…This shows that users are willing to accommodate the system"s behaviour in an attempt to improve retrieval effectiveness. Indeed, in a further 11 queries (1%) of participants inputted English words to overcome (real or perceived) system limitations, which is consistent with the findings in (Petrelli et al 2004).…”

“…Evidence from this study (and previous work (He et al 2002, Petrelli et al 2004), suggests to design the interface in such a way that the translated query is presented to the user who can then better understand why a certain image was retrieved and correct the translated query if needed.…”

“…This is also the case for other forms of cross-language information retrieval, with exceptions such as work on the Clarity project (Petrelli et al, 2004) and at events such as the interactive track of the Cross Language Evaluation Forum (CLEF), known as iCLEF 2 (see, e.g. (Oard & Gonzalo, 2002)).…”

Análise de atos normativos por meio do comportamento de busca de usuários: O caso da Agência Nacional de Energia Elétrica – Aneel

“…Para que um SRI tenha seu foco centrado no usuário é necessário que ele seja construído de acordo com as necessidades deles. Segundo Petrelli (2004) para que um sistema de informação seja efetivo, ele deve ser fiel ao real contexto de seus usuários finais. O desenho de um sistema centrado no usuário requer que o usuário esteja envolvido em todo o processo.…”

Bibliothèques et accès à l’information multilingue : pour en finir avec Babel

“…De nombreux travaux reliés à la RIML textuelle ont été effectués depuis quelques années (Jones 2002 ;Nie 2003 ;Petrelli et al 2004 ;Kishida 2007 ;Ménard 2008). Ces travaux mettent en relief plusieurs problèmes.…”
