Automatic Retrieving of Derived Quechua Verbs

In this paper, I present a method that helps to automatically retrieve derived and inflected Quechua verbs embedded in a corpus. It consists of the formal construction of paradigms and grammars managing the grammatical combinations of verbal suffixes. I use these formalized grammars to extract all the verb forms in a corpus. Then, using the Electronic Dictionary of Quechua verbs that I have previously constructed, and with the help of some elementary statistical tools, I have developed a practical system that allows answering the following socio-linguistic questions: a. how frequent is the use of multi-suffixation of verbs (derived by a combination of two or more suffixes) in everyday life communication? b. Is there a notable difference in this phenomenon between written and oral communication?
