Data Science Group
The group focuses on various topics in Natural Language Processing and Information Retrieval areas, working mainly with text content. One of the long-lasting themes are research topics in which we pay special attention to temporal aspects of text and of long-term document collections such as collections of news articles published over multiple years (e.g., both document timestamps and temporal expressions embedded in text).
In particular, the following research projects have been carried recently:
- Open domain question answering in large news article collections
- Multi-hop question answering and generation
- Timeline generation from news article datasets
- Multiple timeline generation
- Comparative timeline generation
- Information retrieval and access approaches to news collections
- Event time detection
- Named entity retrieval
- Bias detection in text (news articles)
- Text readability estimation
- Keyword extraction
- Temporal Natural Language Inference (TNLI)
- Automatic humor detection and generation
- Legal AI (e.g., dialogue generation)
- Text summarization
- Temporal text collection summarization
- Multi-modal document summarization
The group collaborated or collaborates actively with researchers from: Kyoto University (JP), AIST (JP), Kyoto Sangyo University (JP), University of La Rochelle (FR), Alibaba Group (CN), Nankai University (CN), Karlsruhe Institute of Technology (DE), University of Tsukuba (JP), University of Normandy (FR), Polytechnic Institute of Tomar (PT), University of Porto (PT), IIT Patna (IN), University of Gothenburg (SE), Nanyang Technological University (SG), Takushoku University (JP), Sorbonne University (FR), Polish-Japanese Academy of Information Technology (PL), Universiti Utara Malaysia (MY), Cork Institute of Technology (IE), Fraunhofer Austria (AT) and TuWien (AT).
