Recognize/generate regular languages, i.e., languages specified by regular expressions. recognition problem can be solved in linear time (independent of the size of the automaton). there is an algorithm to transform each automaton into a unique equivalent automaton with the least number of states. This document provides an overview of computational morphology. it discusses how computational morphology deals with processing words and their graphemic and phonemic forms, with applications including spelling correction and hyphenation. After a compact overview of the basic concepts in morphology, this chapter presents the state of the art computational approaches to morphology, concentrating on two level morphology and cascaded rules and describing how morphographemics and morphotactics are handled in a finite state setting. Word form, form: a concrete word as it occurs in real speech or text. lemma: a distinguished form from a set of morphologically related forms, chosen by convention (e.g., nominative singular for nouns, infinitive for verbs) to represent that set. lemma can be also called the canonical/base/dictionary/citation form.

Train on large quantities of data, compile up a model. input unannotated text. use the model to guess where morpheme boundaries occur. the right arrow rule: l:s => e "only but not always." the left arrow rule: l:s <= e "always but not only." the double arrow rule: l:s <=> e "always and only.“ the never rule: l:s /<= e "never.“. This paper starts with a brief introduction to computational morphology, followed by a review of recent work on computational morphology with neural network approaches, to provide an overview of the area. This article reviews research on the unsupervised learning of morphology, that is, the induction of morphological knowledge with no prior knowledge of the language beyond the training texts. Any languages of your choice; you can work in groups, too. addressed in the lectures (in more detail): english, italian, finnish, arabic. principal tool: gf, grammatical framework. also introduced: xfst, xerox finite state tool. these tools can co operate! morphology and syntax for natural languages. currently covering.
