The pos­i­tion is forseen to do research and devel­op­ment in the BMBF-fun­ded pro­ject OKS. This pro­ject aims at the optim­iz­a­tion of human-machine inter­ac­tion with learn­ing con­ver­sa­tional speech inter­faces. Machine learn­ing is already suc­cess­fully used in research for the imple­ment­a­tion of intel­li­gent and nat­ural speech-based per­sonal assist­ants. However, even large ICT enter­prises do not over auto­matic meth­ods for the gen­er­a­tion of dia­log sys­tems.
The aim of the pro­ject is to fill this imple­ment­a­tion gap with tried and tested tools and work pro­cesses for the Ger­man eco­nomy in order to enable the cost-effi­cient devel­op­ment of such speech-based assist­ants. To this end, adapt­ive dia­logue sys­tems shall be cre­ated auto­mat­ic­ally from know­ledge bases and optim­ized by using machine learn­ing, espe­cially rein­force­ment learn­ing. On the basis of this tech­no­logy, sys­tems will be cre­ated that enable speech access to com­plex data struc­tures in every­day pro­fes­sional life and speech-based sup­port in every­day private life. The solu­tions avail­able in basic research have to be val­id­ated with regard to their usage for dia­log sys­tem archi­tec­tures and eval­u­ated with users.
If you have the wish and the right suit­ab­il­ity, you can pur­sue a doc­tor­ate at our chair.

  • The con­crete tasks include, depend­ing on pre­vi­ous know­ledge:
    Deriv­a­tion of dia­log domains and dia­log man­agers from onto­lo­gies and data­base sys­tems
  • Con­cep­tion of dia­logue strategies and dia­logue sys­tems
  • Imple­ment­a­tion of a rein­force­ment learn­ing envir­on­ment for stat­ist­ical dia­logue man­agers (e.g. based on Q-Learn­ing or neural net­works)
  • Con­cep­tion of suit­able Reward func­tions
  • Imple­ment­a­tion of heur­istic and data-driven user sim­u­la­tions
  • Integ­ra­tion of the dia­log man­ager in spoken dia­log sys­tems
  • Eval­u­ation of spoken dia­log sys­tems
  • The oppor­tun­ity for work­ing on a doc­toral dis­ser­ta­tion is given.


  • Suc­cess­fully com­pleted uni­versity degree (Mas­ter, Dip­lom or equi­val­ent) in com­puter sci­ence, com­pu­ta­tional lin­guist­ics or a com­par­able field of study
  • Good pro­gram­ming skills in Python and secure hand­ling of GIT as well as unit tests, ideally exper­i­ence with Con­tinu­ous Integ­ra­tion
  • Good know­ledge in deal­ing with onto­lo­gies, SQL or No-SQL data­bases
  • Interest in con­duct­ing empir­ical stud­ies with test par­ti­cipants or expert eval­u­ations for the eval­u­ation of spoken dia­logue sys­tems
  • Lan­guage skills: Ger­man at the level of a nat­ive speaker, Eng­lish flu­ent in spoken and writ­ten form
  • Good skills in the field of machine learn­ing (train­ing and eval­u­ation), ideally exper­i­ence with rein­force­ment learn­ing
  • Ideally prior exper­i­ence in the devel­op­ment of spoken dia­log sys­tems or nat­ural lan­guage pro­cessing
  • A desire to work in an inter­na­tional and inter­dis­cip­lin­ary envir­on­ment

About Technische Universität Berlin, Quality and Usability Lab

The major­ity of sys­tems and ser­vices that are provided by com­puter sci­ence, elec­trical engin­eer­ing and inform­a­tion tech­no­logy finally are ori­ented towards the needs of their human users. To suc­cess­fully build such sys­tems and ser­vices it is essen­tial to invest­ig­ate and under­stand users and their beha­vior when inter­act­ing with tech­no­logy. On the hand, this under­stand­ing allows to derive design prin­ciples for human-machine-inter­faces and to define require­ments con­cern­ing the sys­tem and its under­ly­ing tech­no­lo­gies. On the other hand, new avail­able tech­no­lo­gies do offer new pos­sib­il­it­ies regard­ing the design of such inter­faces, and the devel­op­ment of new kinds of inter­ac­tion.
The Qual­ity and Usab­il­ity Lab is part of TU Ber­lin’s Fac­ulty IV for Elec­trical Engin­eer­ing and Com­puter Sci­ence and deals with the design and eval­u­ation of human-machine inter­ac­tion. Here, the main sub­jects of our research are human per­cep­tion, aspects of tech­nical sys­tem that are related to the inter­ac­tion, as well as inter­ac­tion design.
