- ZeitschriftenartikelInformation Density and Linguistic Encoding (IDeaL)(KI - Künstliche Intelligenz: Vol. 30, No. 1, 2016) Crocker, Matthew W.; Demberg, Vera; Teich, ElkeWe introduce IDeaL (Information Density and Linguistic Encoding), a collaborative research center that investigates the hypothesis that language use may be driven by the optimal use of the communication channel. From the point of view of linguistics, our approach promises to shed light on selected aspects of language variation that are hitherto not sufficiently explained. Applications of our research can be envisaged in various areas of natural language processing and AI, including machine translation, text generation, speech synthesis and multimodal interfaces.
- ZeitschriftenartikelSearch Challenges in Natural Language Generation with Complex Optimization Objectives(KI - Künstliche Intelligenz: Vol. 30, No. 1, 2016) Demberg, Vera; Hoffmann, Jörg; Howcroft, David M.; Klakow, Dietrich; Torralba, ÁlvaroAutomatic natural language generation (NLG) is a difficult problem already when merely trying to come up with natural-sounding utterances. Ubiquituous applications, in particular companion technologies, pose the additional challenge of flexible adaptation to a user or a situation. This requires optimizing complex objectives such as information density, in combinatorial search spaces described using declarative input languages. We believe that AI search and planning is a natural match for these problems, and could substantially contribute to solving them effectively. We illustrate this using a concrete example NLG framework, give a summary of the relevant optimization objectives, and provide an initial list of research challenges.
