The methods and tools of tuning the block of morphological analysis to subject fields

The class of semantic linguistic processors is considered. The processor extracts information objects and links between them from natural language texts. Its signifi cant component is the block of morphological and lexical analysis. It has a set of additional functions. The block generates semantic attributes of lexical units and extracts the elementary constructions from texts. It has special means of tuning with regard to the features of natural texts and subject fields. The paper highlights the problems of developing the methods and tools to realize these functions.
