Birte Lönneker-Rodman

From September 2006 to November 2008, I was a visiting researcher within the AI group (FrameNet project) at the International Computer Science Institute, Berkeley, CA. I am now at the University of Hamburg, Germany. My main research areas include: semantic resources for Natural Language Processing; computational lexicography; computational approaches to metaphor and figurative language in general; and Cognitive Linguistics. Some of my recent and current projects are presented below, together with relevant publications, events, teaching, and resources. Further information about my previous and future work and activities can be found on my Story Generation web page.

FrameNet and multilinguality

FrameNet is creating an on-line lexical resource for English, based on frame semantics and supported by corpus evidence. In Natural Language Processing, the resource is exploited for shallow semantic tagging or "semantic role labeling". I am researching representation structures and abstraction levels in FrameNet and other lexico-semantic NLP resources. To exemplify the practical consequences for multilingual applications, I am investigating the integration of FrameNet methods and information types into a bilingual online dictionary that I created previously, Online SLO-DE-SLO.

Slovenian FrameNet

At the International Computer Science Institute, we are adapting the FrameNet annotation tool (FrameNet Desktop) to Slovenian. This involved the creation of various related tools and resources. I populated the lexicon part of the FrameNet database with Slovenian data, collected and preprocessed several sample corpora, produced part-of-speech annotated data, and trained an automatic part-of-speech tagger for Slovenian. Several short texts (speeches, stories) have been tagged and loaded into the FrameNet Desktop, where some of them have been annotated with semantic frames in the full-text annotation format.

Related tools and resources

• Automatic ambiguous morphological tagger (part-of-speech tagger) for Slovenian
• Manually disambiguated morphological annotation of Slovenian texts (over 14,000 tokens)
• Word-form generator for Slovenian nouns, verbs, and adjectives
• Slovenian word form lexicon containing more than 600,000 word forms of roughly 6,000 lemmas
• Slovenian parameter file for automatic part-of-speech tagging with the TreeTagger

The Hamburg Metaphor Database

Several years ago, I initiated and created the Hamburg Metaphor Database, an online database of predominantly French and some German metaphors, supported by the Institute for Romance Languages at Hamburg University. The database includes a lexical as well as a conceptual layer; currently, it contains more than 1,600 annotated attestations from corpora. Together with Ernesto De Luca (Magdeburg, Germany), I am now exploring possibilities to convert the Hamburg Metaphor Database into RDF/OWL and to make the product available as an add-on to EuroWordNet.

Computational approaches to non-literal language

Metaphors and other types of non-literal language are a challenge for Natural Language Processing applications. They have a double-layered semantics: consider, for example, the image evoked by a metaphor, and its actual meaning in context. Ideally, translation (including Machine Translation) preserves both the actual meaning and the image - but sometimes, the target language does not offer any lexicalized expression that serves this purpose. Information Retrieval applications, on the other hand, should work with the contextual meaning only; document classification would be influenced negatively if the underlying images were processed. Researchers in the emerging field of Figurative Language Processing are currently exploring techniques, methods, and representational issues related to the computational treatment of non-literal language. We are hoping so see our results integrated into truly semantic-aware NLP systems of the future.
