 Hello, as you probably know, computational morphology deals with the processing of words and word forms, in both their graphemic and phonemic form. It has a wide range of practical applications such as spelling correction and hyphenation. This unit discusses the techniques available to tackle these tasks. In the virtual session, we will first look at the structure of natural language understanding systems, their components and their processing principles. Special emphasis will be put on the lexicon, its structure and the central lexical access mechanisms. Using finite state transducers, we will also give you the opportunity to see morphological parses at work. Use the question sheet with its video links and hyperlinks as default guidance if you don't know where to start. The mastery worksheet is a dynamic multiple choice test with several questions about computational morphology, not difficult after all and especially after the virtual session. One of the practical gives you even more opportunities to apply your knowledge, especially in the area of morphographic alternation. We hope that we've created an interesting unit for you.
