A hierarchical lexical representation for bi-directional spelling- to-pronunciation/pronunciation-to-spelling generation

摘要

We propose a hierarchical framework for integrating a variety of linguistic knowledge sources of lexical represen- tation in English, in order to facilitate their concurrent utilization in language applications. Our unified lexical rep- resentation encompasses information including morphology, stress, syllabification, phonemics and graphemics. Each linguistic knowledge source occupies a distinct stratum in the hierarchy. The merits of the proposed framework is demonstrated on the test bed of bi-directional spelling-to-pronunciation/pronunciation-to-spelling generation.
