Projects
Project leader for BREDT, a research project within the KUNSTI (knowledge development for Norwegian language technology) framework sponsored by the Research Council of Norway (NFR). BREDT finished in 2005. The project webpage is at BREDT , where you will find a demonstrator, some software for analogical modeling, and a demonstrator for anaphora resolution (including a graphical editor, and a possibility to store edited results).
