King, T.C. (author), Van Riemsdijk, M.B. (author), Dignum, V. (author), Jonker, C.M. (author)This paper deals with the problem of automating the contribution of resources owned by people to do work for others, whilst providing a means for owners of resources to maintain autonomy over how, when and to whom their resources are used with the specification of resource use policies. We give representations of requests for resource usage as a...book chapter 2015

Zhu, Y. (author), Heynderickx, I. (author), Redi, J.A. (author)In the past decades, a lot of effort has been invested in predicting the users’ Quality of Visual Experience (QoVE) in order to optimize online video delivery. So far, the objective approaches to measure QoVE have been mainly based on an estimation of the visibility of artifacts generated by signal impairments at the moment of delivery and on a...conference paper 2014

Aydogan, R. (author), Hindriks, K.V. (author), Jonker, C.M. (author)Much attention has been paid to bilateral negotiation in which the dispute is between only two parties. However, automated multilateral negotiation in which more than two negotiating parties need to reach a joint agreement, has received relatively less attention, even though such negotiations are required in many circumstances (e.g. a group of...conference paper 2013

Hindriks, K.V. (author), Jonker, C.M. (author), Pasman, W. (author)Rational agents programmed in agent programming languages derive their choice of action from their beliefs and goals. One of the main benefits of such programming languages is that they facilitate a highlevel and conceptually elegant specification of agent behaviour. Qualitative concepts alone, however, are not sufficient to specify that this...conference paper 2008

Gemert, J.C. (author), Jain, M. (author), Gati, E. (author), Snoek, C.G.M. (author)This paper is on action localization in video with the aid of spatio-temporal proposals. To alleviate the computational expensive segmentation step of existing proposals, we propose bypassing the segmentations completely by generating proposals directly from the dense trajectories used to represent videos during classification. Our Action...conference paper 2015

(author)Pulsars with their periodic pulses and known positions are ideal beacons for navigation. The challenge, however, is the detection of the very weak pulsar signals that are submerged in noise. Radio based approaches allow the use of advanced techniques and methods for the detection and acquisition of such weak signals. In this paper, an effective...conference paper 2012

Oren, N. (author), Van Riemsdijk, M.B. (author), Vasconcelos, W. (author)This paper seeks to address the question of preference alignment in normative systems. We represent detached obligations and goals as preferences over outcomes, and describe when deterministic behaviour will occur within a MAS under specific system instantiations. We then investigate what obligations an agent with so called normative power...conference paper 2013

Kehl, C. (author), Tutenel, T. (author), Eisemann, E. (author)Visualising large-scale geospatial data is a demanding challenge that finds applications in many fields, including climatology and hydrology. Due to the enormous data size, it is currently not possible to render full datasets interactively without significantly compromising quality (especially not when information changes over time). In this...conference paper 2013

Vliegendhart, R. (author), Liem, C.C.S. (author), Larson, M.A. (author)In this paper, we present a social media based approach to finding anchors in video archives. We use social activity on Twitter to find topics on which people have questions about in order to select suitable anchors. The experiments were carried out on the MediaEval Search and Anchoring in Video Archives Task (SAVA) data set, consisting of 68...conference paper 2015

Xu, J. (author), Broekens, D.J. (author), Hindriks, K.V. (author), Neerincx, M.A. (author)Mood contagion is an automatic mechanism that induces a congruent mood state by means of the observation of another person's emotional expression. In this paper, we address the question whether robot mood displayed during an imitation game can (a) be recognized by participants and (b) produce contagion effects. Robot mood was displayed by...conference paper 2014

(author)It remains a challenge with current state of the art technology to use BDI agents to control real-time, dynamic and complex environments. We report on our effort to connect the GOAL agent programming language to the real-time game UNREAL TOURNAMENT 2004. We focus in particular on the design of a suitable interface to manage agent-bot interaction...conference paper 2010

Scholte, K. (author), Rothkrantz, L.J.M. (author)Many services provide weather forecasts, including severe weather alerts for the marine. It proves that many ships neglect the warnings because they expect to be able to handle the bad weather conditions. In order to identify possible unsafe situations the Coast Guard needs to observe marine vessel traffic 24 hours, 7 days a week. In this paper...conference paper 2014

Wojdel, J. (author), Wiggers, P. (author), Rothkrantz, L.J.M. (author)This paper describes the gathering and availability of an audio-visual speech corpus for Dutch language. The corpus was prepared with the multi-modal speech recognition in mind and it is currently used in our research on lip-reading and bimodal speech recognition. It contains the prompts used also in the well-established POLYPHONE corpus and...conference paper 2002

A distinction can be made between getting the right information and having the rights to get that information. The first is an information filtering and relevance problem, the second is a...conference paper 2012

The framework allows the rapid construction of a multimodal, multi-device, and multi-user communication...conference paper 2009

Koenderink, J. (author)The egg-rolling behavior of the graylag goose is an often quoted example of a fixed-action pattern. The bird will even attempt to roll a brick back to its nest! Despite excellent visual acuity it apparently "takes a brick for an egg." Evolution optimizes utility, not veridicality. Yet textbooks take it for a fact that human vision evolved so as...conference paper 2011
