... recognition uses. We con- ducted a mapping from the ARPAbet phonemes to the international phonetic alphabet (IPA) phonemes and we grouped the IPA phonemes based on the phoneme classification documented ... Conclusion In this paper, we have focused on the task of automa- tizing the naming process and described a computa- tional approach to generate neologisms with homo- phonic puns...

... rohini}@cymfony.com Abstract This paper presents a new bootstrapping approach to named entity (NE) classification. This approach only requires a few common noun/pronoun seeds that correspond to ... separation of features into several orthogonal views. In case of NE classification, usually one view uses the context evidence and the other relies on the lexicon evidence. Lea...

Conclusions Our conclusions regarding the hybrid represen- tation approach of intensional logic plus NIKL -based axioms to define constants are based on three kinds of efforts: ... constraints to eliminate candidate referents.
