Part 1 Introduction: the need for a computational lexicon; what is thelexicon?; morphology; segmentation and orthography; word structure; the unitof storage; lexical redundancy; preprocessing and look-up; what this book isabout. Part 2 Morphographemics: generative phonology; formalizingphonological rules; transducers; the two-level model; the transducer version;the two-level rule notation; the lexicon and word grammar interface; formalissues. Part 3 Word structure rules: context free rules; features andcategories; the word structure formalism; varieties of unification; the termunification enhancements; the role of the word grammar; an illustrative. Part4 Feature propagation in the word grammar: beyond structural rules; othertheories of feature propagation; feature-passing conventions; usefulness ofconventions. Part 5 Lexical rules: lexicon expansion; the role of lexicalrules; format of lexical rules; completion rules; multiplication rules;consistency checks; application of lexical rules; lexicon management; theadvantages of lexical rules. Part 6 A description of English: overview of themodel; what is a morpheme?; stems and affixes; morphographemics; lexicalrules and defaults; syntactic features; inflection and derivation;classifying words; the word grammar; feature conventions; illustrativeexamples; over-generation; a caveat. Part 7 The implemented system:facilities provided; the lexicon; spelling rules; the word grammar; theanalysis process; dictionary command interpreter; other implementationissues; practical considerations. Part 8 Limitations and extensions: spellingrules; word grammar and feature conventions; lexical entries and rules;idioms; compounds; irregularity and blocking; the implemented system.Appendices: definition of the linguistic notation; syntactic andmorphological features; some sample lexical entries; a description of Englishmorphology; sample results of lexical look-up; formal definitions; complexityof two-level morphology.
