Abstract :
This paper describes an approach for the partitioning of large dictionaries which can be used in document analysis. It introduces a concept of virtual views on the dictionary. The architecture of the dictionary system is based on redundant hashing techniques. The system distinguishes between the two main modules: the dictionary generator and the dictionary controller. Our tests comparing the dictionary with standard UNIX utilities show that dictionary look-up is very fast
