Dr. Sven Schmeier studied physics and computer science at Saarland University from 1989 to 1997 and graduated by receiving a Diplom (MSc) in computer science. His PhD-Thesis in Computational Linguistics is about “Exploratory Search on Mobile Devices”.
In 1998 he started working at the German Research Center for Artificial Intelligence (DFKI) as a researcher and software developer in several projects.
Sven was co-founder of the company XtraMind Technologies GmbH (now Sematell GmbH) in 2000 and was the head of the research department until 2005.
Since 2007 he is back at the DFKI as Chief Engineer leading several research and industrial projects in the area of Natural Language Processing, Machine Learning and Big Data.
Also in 2007 Sven founded the DFKI spin-off company Yocoy Technologies GmbH together with his colleagues Prof. Hans Uszkoreit and Dr. Feiyu Xu. Under his technical leadership as CTO more than 30 mobile applications as multilingual communication assistants for English, Chinese,French, German and Spanish speaking tourism markets, available for iOS and Android with users from more than 100 countries have been developed.
In 2017 Sven has been promoted to be the Associate Head of Language Technology Lab of DFKI consisting of more than 30 researchers, engineers and consultants at different levels.
- Leading small to midsize groups of international experts in AI and Computer Science
- Creating products from scratch to successful market entry

Ph.D. Computational Linguistics. Thesis title: Exploratory Search On Mobile Devices, Institute for Computational Linguistics, University of Saarland 
The goal of my thesis was to provide a general framework (MobEx) for exploratory search beyond the document centered approaches. The central part was the design, implementation of several core modules for on-demand unsupervised information extraction. These core processing elements, combined with a multitouchable user interface specially designed for mobile devices have been finally implemented in a research prototype.
In several evaluations I was able to show that the developed ad-hoc interactive Query Disambiguation, Named Entity Recognition, and Relation Extraction components compare with current State-Of-The-Art supervised and semi-supervised approaches. Furthermore I analysed the prospects and limitations of the framework and the prototype in several user evaluations.
Master’s Degree in Computer Science, Thesis title: PASHA II – A Personal Assistant for Scheduling Appointments
During my master thesis I implemented a Multi Agent System in which cooperating agents autonomously scheduled appointments on behalf of their users. The agents were connected to the Unix CM (Calendar Managment) system which was popular that time. The scheduling process was done completely by negotiation between these agents taking (underspecified) temporal and spatial constraints into account.
In the research project COSMA the agents have been connected to a natural language dialogue system. With this users could communicate in natural language with the agents and schedule appointments without noticing whether they were communicating with individuals or agents.
