Eickhoff, C. (author), De Vries, A.P. (author)Crowdsourcing successfully strives to become a widely used means of collecting large-scale scientific corpora. Many research fields, including Information Retrieval, rely on this novel way of data acquisition. However, it seems to be undermined by a significant share of workers that are primarily interested in producing quick generic answers...journal article 2012

Rijcken, T. (author), Stijnen, J. (author), Slootjes, N. (author)The Dutch Delta Program is currently developing new government policies for flood protection and fresh water supply. Decision support instruments have to address the program’s technical and political complexity. The water system functions are highly interwoven and would benefit from an integrated approach on a national level, with decisions...journal article 2012

Gunawan, L.T. (author), Fitrianie, S. (author), Brinkman, W.P. (author), Neerincx, M.A. (author)Despite the growing awareness of the untapped potential of the affected population in a disaster situation, their inclusion in a disaster management is extremely limited. This study aims to survey the literature to see whether utilizing the affected people and prevalent mobile technology can be used during disaster response. The idea is to...conference paper 2012

Gunawan, L.T. (author)The research focuses on guiding the affected population towards a safe location in a disaster area by utilizing their self-help capacity with prevalent mobile technology. In contrast to the traditional centralized information management systems for disaster response, this research proposes a decen- tralized computer-supported management system...doctoral thesis 2013

Rudinac, S. (author)To facilitate finding of relevant information in ever-growing multimedia collections, a number of multimedia information retrieval solutions have been proposed over the past years. The essential element of any such solution is the relevance criterion deployed to select or rank the items from a multimedia collection to be presented to the user....doctoral thesis 2013

Rijcken, T. (author), Christopher, D.K. (author)The research project ‘SimDelta’ builds on novel internet technology to support the development of the Rhine-Meuse delta water infrastructure. It has three goals: education, organisation of research and design studies, and stakeholder polling. A current question is how the SimDelta technology could be made transferable to systems outside Europe,...journal article 2013

Basak, Debarshi (author), Loni, B. (author), Bozzon, A. (author)Crowdsourcing and Human computation have enabled industry and<br/>scientists to create innovative solutions by harnessing organised<br/>collective human effort. In human computation platforms, it is<br/>observed that workers spend large amount of time searching for<br/>appropriate tasks due to lack of effective task discovery mechanism. This...conference paper 2014

Kovacsova, N. (author), de Winter, J.C.F. (author), Hagenzieker, Marjan (author)In the Netherlands, 30% of fatal crashes between 2010 and 2015 involved a cyclist [1], with a large portion of these crashes occurring at intersections in urban areas. Contributing factors to driver-cyclist collisions at intersections are not only inadequate visual search, but also incorrect expectations about the other’s intentions [2]....conference paper 2017

Tidball, B.E. (author)User centered design of products, services, and systems is widely accepted. Numerous user research tools and methods exist to engage users and gather users’ insights to inform the design process. Unfortunately, time, effort, and expense of many tools often delay the availability of user insights. To address this concern, a series of studies...doctoral thesis 2017

Thepreferences of individual group members often diverge, but it isimportant to keep everyone in the group satisfied during the entiretrip. We propose a method to consider the preferences of all thepeople in the group....conference paper 2018

(author)A common challenge with processing naturalistic driving data is that humans may need to categorize great volumes of recorded visual information. By means of the online platform CrowdFlower, we investigated the potential of crowdsourcing to categorize driving scene features (i.e., presence of other road users, straight road segments, etc.) at...journal article 2018

(author)Training machine learning (ML) models for natural language processing usually requires large amount of data, often acquired through crowdsourcing. The way this data is collected and aggregated can have an effect on the outputs of the trained model such as ignoring the labels which differ from the majority. In this paper we investigate how label...conference paper 2018
