GRK 1994: Adaptive Informationsaufbereitung aus heterogenen Quellen

点击翻译按钮获取中文摘要

The importance of thorough research under tight deadlines is increasing rapidly and the consequences of the quality of the research results are far-reaching, especially for decision making processes. At the same time, the amount of information is growing exponentially and there is a continual increase of complexity, heterogeneity, and a high variation in the quality of electronic information sources.The vision of this graduate program is to extract structured knowledge from heterogeneous sources using automated means in order to create dossiers of stylistically homogeneous content. Within this project, we develop methods that are able to adapt to different genres and domains, so that the results can easily be transferred to other tasks and – in later phases of the project – to other user groups and languages. The first phase of the graduate program focuses on multi-document summarization (MDS) as a prototypical task. As a representative use-case, we choose German documents on educational topics extracted from heavily heterogeneous sources. The German Institute for International Educational Research (DIPF) in Frankfurt/Main provides a common German document collection and also formulates user requirements and supports large-scale evaluations at different stages of the graduate program. Adaptive information processing is a complex task which requires extensive research on integrated methods that incorporate knowledge of the involved scientific disciplines. The main research questions of the graduate program are (A) the computational linguistic modeling of discourse phenomena in heterogeneous text genres, (B) the development of language technologies for heterogeneous MDS, (C) the representation and analysis of text-induced structures, (D) and the criteria and mechanisms for selecting and assessing the quality of heterogeneous sources and resulting summaries in information management. By investigating these questions in a densely connected research plan, the four research areas will jointly address our guiding research topic in breadth and depth.The qualification concept includes a collaboration across disciplines and locations, intensive international networking, scientific consultation of at least two PhD advisors and of one international co-advisor for each doctoral project, and the responsible participation of excellent post-doctoral researchers in doctoral supervision and training jointly with experienced advisors. The graduate program will form a central location for the qualification of young researchers in this highly demanded academic field in the Rhine-Main-Neckar region.
