In collaboration with the Rotterdam public transport organisation (RET), Allerto and the Artificial Intelligence group (Tibor Bosse & Romy Blankendaal) at the VU, the Network Institute developed a virtual reality training application to help bus drivers cope with aggressive passengers.
The application uses true immersive virtual reality by using VR-goggles and VR-controllers to give the user control over a virtual bus driver. The bus driver will be confronted with passengers who could get aggressive if not treated properly. By making the correct choices, the bus driver can avoid aggression and solve the situation with the potential for violence.
The VR training will be used beside the more traditional classroom and role-playing sessions to make sure bus driver are well instructed in how to handle potentially aggressive passengers.
Over the past two weeks there’s been a lot of media attention about the Babbeltruc App. This tablet app was created by the Network Institute in collaboration with Artificial Intelligence (Tibor Bosse & Laura van der Lubbe) at the VU and the KBO-PCOB (a national elderly organisation) to help the elderly in coping with doorstep scams.
The app confronts the users with several scenarios where a virtual human tries to either gain access to their house or get sensitive information. The user has to choose from several possible answers at each step and is then asked to say aloud the chosen response. A newly developed algorithm (by Daniel Formolo, AI-CS-VU) will determine how assertive the response was spoken.
With all this information the app can advise the user in getting better at avoiding being scammed.

Health care organization “Ons Tweede Huis” (Our Second Home) held a fun and informative festival in order to celebrate their 50th anniversary. To show what the future could hold for engaging, entertaining and caring for their patients, the Tech Labs of the Network Institute lent a set of Virtual Reality equipment. Using the head-mounted-display visitors got an idea of what this relatively new technology could mean for them and their family in care of Ons Tweede Huis.
The festival was a great success and many visitors tried on the VR set.

The Network Institute hosts the 10th ACM Conference on Web Science, 27-30 May 2018. It is a wonderful opportunity and a great pleasure for the Network Institute to be able host the 10th ACM conference on Web Science, WebSci’18, at the Vrije Universiteit Amsterdam this year.
Web Science is a unique conference where a multitude of disciplines converge in a creative and critical dialogue with the aim of understanding the Web and its impacts. Web Science participants are from diverse fields including (but not limited to) art, anthropology, computer and information sciences, communication, economics, humanities, informatics, law, linguistics, philosophy, political science, psychology, and sociology. The conference particularly welcomes contributions that seek to cross traditional disciplinary boundaries, that describe original research, analysis, and practice in the field of Web Science, and that discusses novel and thought-provoking ideas.
WebSci’18 is chaired by former network Institute director Hans Akkermans. Keynote speakers will be, amongst others, Sir Tim Berners-Lee, the inventor of the World Wide Web, and recipient of the 2016 Turing award, and José van Dijck, president of the KNAW.
Apply for interdisciplinary research projects with 2 student assistants
Deadline 8 June 2018 at 12.00 pm
The Network Institute’s (NI) Academy Assistants program (NIAA) is now entering its eighth year. Initially funded through a KNAW grant and aimed at combining social sciences and computer science research, it has since been adopted by the Network Institute and opened up for other interdisciplinary projects which fall within the NI’s research themes. The Academy Assistants program aims at promising high-potential master students who want to conduct scientific research and possibly pursue an academic career. Last year, six Academy Assistant proposals were funded, this year, the program will also be able to fund six to seven projects.
This is a call for new proposals to start from October 2018 onwards. The program aims to bring together scientists from different disciplines; therefore the projects must combine methods and themes from two different disciplines affiliated with the NI. For each awarded project, the program funds two student research assistants (0,2 FTE) for a period of ten months. The intended outcome of the projects should be papers and/or research proposals. In addition, at the end of the project (July 2019) we will publish proceedings of this year’s project.
On Friday 26 Jan the Network Institute received a visit from a high ranking delegation of the Ministry of the Interior (“Binnenlandse Zaken”), headed by Mevr. Simone Roos, one of the highest ranking civil servants in The Hague. Mrs. Roos was accompanied by a number of her colleagues from The Hague, and by Mrs. Marjolein Janssen, member of the Board of the University. The delegation had an inspiring session with researchers from the Network Institute consisting of Academy Assistants, PhD students and senior academic staff. Topics of discussion were the social effects of the increasing digitisation of society, and the roles and responsibilities of citizens and government in this process. They were impressed with how successful the Network Institute is in bridging the gap between different academic disciplines, and how it uses this interdisciplinary setting to study questions with a high social relevance.
Doorstep scams are scams in which a con artist has a convincing, but fraudulent, story with the purpose of coming into your house and/or stealing money. Often these scams appear at the doorstep, for example when somebody wants to enter your house because they must check the electricity or with similar excuses. However, it also happens that the con artist calls you by phone (telling a story about fraudulent payments, aiming to get banking information for example) or approaches you on the street. Elderly people are often the victims of such doorstep scams, which usually have a high impact on their lives.
Within this project, we are creating a tablet application that can be used to train how to verbally act in such situations. The users both learn what to say, and how to say it, in various scenarios. They will both receive automated feedback on how they dealt with the different situations (what they said) and on the assertiveness of their voice (using an algorithm to analyze vocal signals).
This project is a collaboration between the VU and Unie KBO-PCOB.

Michel ter Hark, decaan Geesteswetenschappen, vindt dat nergens zo gemakkelijk interdisciplinaire vraagstukken lijken te ontstaan als aan de VU. De organisatie van het onderzoek in de vorm van iOzi’s draagt hier zeker toe bij. Maar het aantal iOzi’s dat behalve interdisciplinair ook interfacultair is, is beperkt en juist hier liggen de kansen van onderzoeksgebonden onderwijs dat aansluit bij de brede belangstelling van bachelorstudenten.

Piek Vossen, prominent lid van het Netwerk Instituut, en Frank van Harmelen, lid en voormalig directeur van het Netwerk Instituut zijn beiden benoemd als leden van de Koninklijke Nederlandse Academie van Wetenschappen. De KNAW telt 550 leden uit alle geledingen van de wetenschap, en leden worden voor het leven benoemd.
Frank van Harmelen is hoogleraar kennisrepresentatie en redeneren aan de Afdeling Informatica. Hij is een prominent onderzoeker op het gebied van de kunstmatige intelligentie. Het doel van zijn onderzoek is dat computers zelf kunnen denken en redeneren. Daarvoor moet informatie op een voor computers logische manier beschikbaar zijn. Van Harmelen is een van de grondleggers van het zogeheten semantische web, een beschrijving van informatie op het internet waarmee computers aan de slag kunnen. De regels voor een semantisch web zijn inmiddels opgenomen in de standaarden voor www. Ook maakte Van Harmelen met zijn groep de Nederlandse richtlijn voor borstkanker begrijpelijk voor computers.
Piek Vossen is hoogleraar computationele lexicologie. Hij ontwikkelt computermodellen die taal begrijpen. Vossen leidde EuroWordNet, een project waarbij woorden in acht talen via hun betekenis met elkaar verbonden worden en samen een groot netwerk (spinnenweb) vormen. Computers gebruiken zulke netwerken om het verschil te zien tussen bijvoorbeeld bank als spaarbank en zitbank in een tekst. Verder wordt Vossen beschouwd als de belangrijkste Nederlandse onderzoeker op het gebied van text-mining. Hij bedacht de ‘Geschiedenisrecorder’: een computersysteem dat massaal nieuwsberichten leest, gebeurtenissen herkent en aan elkaar koppelt om zo automatisch de geschiedenis over jaren vast te leggen. Vossen werkte zo’n tien jaar in het bedrijfsleven voor zijn bliksemcarrière in de wetenschap begon.
This project introduces the concept of “virtual bad guys”: intelligent virtual agents that take a negative or even aggressive stance towards the user. Although they pave the way to various interesting applications, it is hard to create virtual bad guys that are taken seriously by the user, since they are typically unable to apply serious sanctions. To address this issue, this study experimentally investigated the effect of “consequential” agents that are able to physically threaten their human interlocutors. A consequential agent was developed by equipping users with a (non-functioning) device, through which they were made to believe the agent could mildly shock them. Effects on participants’ levels of anxiety and (physiological and self-reported) stress were measured, and the role of presence and perceived believability of the virtual agent was assessed. The consequential agent triggered a stronger physiological stress response than the non-consequential agent, whereas self-reported levels of anxiety and stress did not significantly differ. Furthermore, while presence and believability were substantially associated with users’ stress response, both states did not mediate or explain the effect of a consequential vs. non-consequential agent on stress, as they did not significantly differ between conditions. Implications of these findings and suggestions for follow-up studies on “virtual bad guys” are discussed.
The Tech Labs helped develop the virtual environment, using the custom developed Galvanic Skin response sensor and supplying the VR equipment to run the experiment.
