Description This paper describes PC-KIMMO, a morphological parser based on Kimmo Koskenniemi's model of two-level morphology (Koskenniemi 1983). While PC-KIMMO was adequate to decompose a word into morphemes, it was not able directly to compute the part of speech of a derivationally complex word or return a word's inflectional features--precisely the information required for syntactic parsing. These deficiencies have now been remedied by adding a unification-based word grammar component to version 2 of PC-KIMMO which can provide parse trees and feature structures. A substantial analysis of English for use with PC-KIMMO is also described. Why do morphological parsing? Parsing is a standard technique used in the field of natural language processing. When you think of parsing, you likely think of syntactic parsing. But before a syntactic parser can parse a sentence, it must be supplied with information about each word in the sentence. For instance, to parse the sentence The cat chased the rat, a parser must know that cat is a singular noun, chased is a past tense verb, and so on. In English, such
