ABSTRACT This paper reports the results of an international web-based survey on the use of field studies in the design and evaluation of interactive systems, which was conducted between December 2006 and February 2007. The results suggest that the advantages and disadvantages of field methods are generally well understood, but guidance is needed in their application and use. Field studies were ...

We describe methods and practices of early user involvement and human-centred design: how researchers and designers, in the ICT industry, attempt to cooperate with end-users, with the goal of making a better match with end-users’ needs and preferences. We describe six (dance) moves: participatory design, ethnographic fieldwork, lead-user approach, contextual design, codesigning, and empathic de...

The validity of semantic inferences depends on the contexts in which they are applied. We propose a generic framework for handling contextual considerations within applied inference, termed Contextual Preferences. This framework defines the various context-aware components needed for inference and their relationships. Contextual preferences extend and generalize previous notions, such as select...

The identification of the scientific production and the evaluation of the researchers is a problem we are facing at present times. Bibliometric methods use mainly statistical tools and their results are of quantitative nature. Consequently, this approach does not provide any tools of qualitative evaluation. It is for this reason we suggest to examine the specific details of the bibliographic re...

While efforts to address the management of chronic diseases in the context of large, urban hospitals are underway, the literature is silent on how to facilitate such efforts in the community clinics that provide services to many chronic-care patients who are medically underserved. We offer a contextualist framework for developing IT-enabled chronic care management in community clinics. To under...

Three realities (mindscapes) used in constructing knowledge and their traditional research methodologies are discussed as a basis for proposing a research agenda and strategy for rural education. In order to study rural education, the authors propose the use of conceptual empiricism and contextual appraisal consisting of four domains; personal (self), instruction (class), institutional (school)...

This paper is a comment on Contextual Design, a method frame proposed by Beyer & Holtzblatt (1998) for redesigning work in conjunction with developing technological support for this work. It is scrutinized in which ways Contextual Design is a participatory approach and in which ways Contextual Design is suitable for capturing practices, meanings and challenges in the work environments to be red...

Automatic Construction of a Contextual Valence Shifters Lexicon The research presented in this paper takes place in the field of Opinion Mining, which is mainly devoted to assigning a positive or negative label to a text or a sentence. The context of a highly polarized word plays an essential role, as it can modify its original polarity. The present work addresses this issue and focuses on the ...

In opinion mining, many linguistic structures, called contextual valence shifters, may modify the prior polarity of items. Some systems of sentiment analysis have tried to take these shifters into account, but few studies have focused on the identification of all these structures and their impact

Designing 3D objects from scratch is difficult, especially when the user intent is fuzzy and lacks a clear target form. We facilitate design by providing reference and inspiration from existing model contexts. We rethink model design as navigating through different possible combinations of part assemblies based on a large collection of pre-segmented 3D models. We propose an interactive sketch-t...
