PhD position and Post-doc position: Privacy-respecting dialog systems
=============================================
(Computational Linguistics, Computer Science or similar)

Conversational interfaces based on deep learning are becoming more and
more ubiquitous. However, the massive amounts of stored speech and
text data that is needed for training state-of-the-art models raises
serious privacy concerns for its users. Each spoken message may
potentially reveal information about the user's personality, may
contain critical information (credit card numbers, passwords, etc.),
and may convey sensitive information (ethnicity, age, health status,
etc.). Voice recordings may even be malevolently used to build
synthesized voiced to impersonate users.

The Spoken Language Systems group at Saarland University is seeking
new ways to provide dialog technology that is 'private by design' by
means such as e.g. privacy-preserving machine learning. To this end,
we are anticipating the availability of a PhD position and a Post-Doc
position starting at the beginning of 2019.

Ideal candidates for either position would have:

  1. A good understanding of not just NLP, but of dialog phenomena in
     particular. Here, an understanding of how privacy-relevant
     information may arise as a result of dialog behavior (rather than
     as part of a single utterance) is desirable.

  2. Excellent knowledge of machine learning, experience with
     weakly-supervised methods a plus.

  3. Knowledge of and experience with scientific evaluation
     methodologies.

  4. Excellent programming skills, experience with RESTful APIs a plus.

  5. Experience with architecting large, heterogeneous, modular and
     distributed systems.

Salaries: The PhD position will be 75% of full time on the German E13
scale (TV-L). The Post-Doc position will be 100% of the full time on
the German E13 scale (TV-L). The appointments will be for three years
with possible extensions subject to follow-up funding.

About the department: The department of Language Science and
Technology is one of the leading departments in the speech and
language area in Europe. The flagship project at the moment is the CRC
on Information Density and Linguistic Encoding. Furthermore, the
department is involved in the cluster of excellence Multimodal
Computing and Interaction. It also runs a significant number of
European and nationally funded projects. In total it has seven faculty
and around 50 postdoctoral researchers and PhD students.
