Abstract
Representative sets of software systems for computational morphology are evaluated as candiates for a general morphological program module in the context of computer-aided word class tagging. They are considered as both programming tools and representations of linguistic Knowledge. The systems, which are found to be relatively neutral with respect to linguistic theory, can be grouped into a general-purpose and a special-purpose type. Pattern matching in them is described as a high-level feature applied to the computational treatment of phenomena characteristic of morphological analysis: lexical lookup, morphotactics, and morphophonemic alternation. The systems are found to perform similarly in simple applications, but significantly differently in more complicated ones where integrated and well-structured solutions are sought.
