Parsing coordination units is important as a part of preprocessing phase of an NLP tool. In this paper, a method for modelling and recognition of coordination of some noun phrase classes in Serbo-Croatian is presented. The model is based on local grammars and can be applied to a digital text by using an equivalent finite-state transducer. Therefore, the implementation of the model is efficient and can be embedded as a preprocessor in a system that performs further linguistic analysis of a digital text. In addition to the recognition of a coordination of noun phrases, we discuss possibilities to check some agreements between such a unit and other constituents of a sentence.
