    Joint Grammar Development by Linguists and Computer Scientists
    (2008) Maxwell, Michael; David, Anne
    For languages with inflectional morphology, development of a morphological parser is often a bottleneck for further development of computational linguistic capabilities. We focus on two difficulties: first, finding people with expertise in both computer programming and the linguistics of a particular language, and second, the short lifetime of software such as parsers. We then describe a methodology we have developed to split the task of building a parser for a language into two tasks, descriptive grammar development and formal grammar development. The two grammars are combined into a single document using Literate Programming. The formal grammar is designed not to be dependent on a particular parsing engine’s programming language, so that it can be readily ported to a new parsing engine, thus helping solve the software lifetime problem.

    Interoperable Grammars
    (2008) Maxwell, Michael; David, Anne
    For languages with significant inflectional morphology, development of a morphological parser is often a prerequisite to further computational linguistic capabilities. We focus on two difficulties for this development: the short lifetime of software such as parsing engines, and the difficulty of porting grammars to new parsing engines. We describe a methodology we have developed to promote portability, using a formal declarative grammar written in XML, which we supplement with a traditional descriptive grammar. The two grammars are combined into a single document using Literate Programming. The formal grammar is designed to be independent of a particular parsing engine’s programming language, thus helping solve the software lifetime and portability problems.
