Do you care about creating intelligent systems that connect people to information that’s useful and reliable? We are looking for three PhD students who are interested in conducting research into conversational search systems that help users discover consumer services (news, music, games, apps, etc). The research will take place in the DReaMS Lab, a collaboration between the Vrije Universiteit Amsterdam, the University of Amsterdam, and the Huawei Consumer Business Group. Our philosophy is to support consumer exploration and discovery using machine intelligence in ways that are humane and safe.
The three positions that we are offering focus on three different aspects of multi-modal conversational search:
Position 1: User intent modeling and prediction
How can we help machines develop an understanding of a user’s multi-modal intent? Can we learn rich preference, task, and context representations for this purpose?
Position 2: Online evaluation from conversational user interactions
How should a conversational assess its own success or failure while offering users multi-modal content from a range of sources based on mobile or voice-based interaction signals?
Position 3: Unbiased learning to rank from conversational interactions
How can a conversational system learn from past interactions with users so as to inform its future actions? What types of presentation bias emerge in a conversational setting and how can we correct for this?
We strongly encourage applications coming from a unique perspective. Don’t just send us your CV but tell us how your background fits with the position of your choice and with the aims of the lab.
What are you going to do?
You are expected to:
- create, evaluate and describe novel algorithms and architectures for conversational search and complex question answering;
- integrate and evaluate such algorithms in experimental scenarios, with a focus on multi-modal consumer services;
- present research results at national and international conferences, workshops and journals;
- become an active member of the research community and to collaborate with other researchers, both within and outside the Informatics Institute;
- pursue and complete a PhD thesis within the appointed duration of four years;
- assist in teaching activities, such as teaching labs and tutorials or supervising bachelor and master students.
What do we require?
- A Master’s degree in Computer Science, Artificial Intelligence, or a closely related field;
- a thorough understanding of both information retrieval and machine learning;
- an interest in algorithm development and in their implications for people impacted by those algorithms;
- solid programming skills and experience in Python and machine learning frameworks;
- the ability to work in multidisciplinary teams;
- a good knowledge of English (written and spoken);
- knowledge of an European language other than English. This is not required but very helpful as we will be working with multiple European languages.
A temporary contract for 38 hours per week for the duration of 4 years (the initial contract will be for a period of 18 months and after satisfactory evaluation it will be extended for a total duration of 4 years). This should lead to a dissertation (PhD thesis). We will draft an educational plan that includes attendance of courses and (international) meetings. We also expect you to assist in teaching undergraduates and master students.
The salary, depending on relevant experience before the beginning of the employment contract, will be €2,395 to €3,061 (scale P) gross per month, based on a full-time contractof 38 hours a week. This is exclusive 8% holiday allowance and 8,3% end-of-year bonus. A favourable tax agreement, the ‘30% ruling’, may apply to non-Dutch applicants. The Collective Labour Agreement of Dutch Universities is applicable.
