Abstract

We describe the development of a new German parser that
uses a hybrid approach, combining a hand-written rule-based grammar with a probabilistic disambiguation system. Our evaluation shows that this parsing approach can compete with state-of-the-art systems both in terms of efficiency and parsing quality. The hybrid approach also allows for the integration of the morphology tool GERTWOL, which leads to a comparatively high precision for core syntactic relations.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
