The TTLab (Text Technology Lab), headed by Prof. Alexander Mehler, is part of the Department of Computer Science and Mathematics (Fachbereich Informatik und Mathematik) at the Goethe Universität in Frankfurt. It investigates formal, algorithmic models to deepen our understanding of information processing in the humanities. We examine diachronic, time-dependent as well as synchronic aspects of processing linguistic and non-linguistic, multimodal signs. The Lab works across several disciplines to bridge between computer science on the one hand and corpus-based research in the humanities on the other. To this end, we develop information models and algorithms for the analysis of texts, images, and other objects relevant to research in the humanities.

Open Full-Time Position (E13) for ENTAILab in SPP 2431: New Data Spaces for the Social Sciences
by
At the Institute for Computer Science (Prof. Dr. Alexander Mehler), Department of Computer Science and Mathematics at Goethe University Frankfurt, a position for a
Research Assistants (m/f/d)
(E 13 TV-G-U, 100% full-time)is available at the earliest possible date for a period of three years within the ENTAILab project – research infrastructure and innovation lab. The salary scale is based on the job characteristics of the collective agreement applicable to Goethe University (TV-G-U).
The project is part of the priority program (SPP) New Data Spaces for the Social Sciences, which is funded by the German Research Foundation (DFG) (see https://www.new-data-spaces.de). The aim of the project is to establish a research-oriented infrastructure for novel data in survey research. To this end, a method-oriented innovation laboratory for novel methods in survey research is to be set up, which will develop and test methods of machine learning and artificial intelligence in cooperation with the projects of the SPP. The subject of the methods to be developed is multimodal data and thus not primarily or exclusively linguistic research data.
You are expected to collaborate in the project and actively participate in the workshops and events of the SPP. We are looking for a highly qualified individual with a keen interest in working in the field of cutting-edge research infrastructures and in the team-oriented development and application of innovative, research-oriented methods in the field of survey research and the social sciences. With the SPP New Data Spaces for the Social Sciences and the Text-Technology Lab, in which the position will be embedded, we offer two research-strong, internationally oriented working environments in the areas of computational humanities, multimodal computing, machine learning and artificial intelligence. This also includes financial resources for conference participation and individual career development.
Requirements
- Completed academic university degree (e.g. Master’s) in a relevant subject with a focus on information science
- Very good knowledge of English (C1)
- Proven experience in the field of databases and machine learning or artificial intelligence methods
- Extensive programming knowledge in Java, Python or similar
- Knowledge of virtualization technologies such as Docker, Kubernetes or similar
- An interest in social science issues is desirable.
Please send your application with the usual documents (cover letter, CV, copies of certificates) electronically in a combined PDF document by 08.10.2024 to Prof. Dr. Alexander Mehler: mehler@em.uni-frankfurt.de.

New Publication Accepted for the 2nd Workshop on Legal Information Retrieval meets AI (LIRAI24)
by
Our paper, “Finding Needles in Emb(a)dding Haystacks: Legal Document Retrieval via Bagging and SVR Ensembles,” has been accepted to the 2nd Workshop on Legal Information Retrieval Meets AI. In this work, we present an approach that leverages embedding spaces, bootstrap aggregation, and SVR ensembles to retrieve legal passages efficiently, demonstrating improved recall compared to baseline methods (0.849 > 0.803 | 0.829):
