ABSTRACT:
A technique for constructing a dictionary word list for use in a data compressor is provided by determining a set of words that are included in the dictionary word list and sorting each subset of words having a common starting character by lengths of the words. Partitions are formed and identified based on the common starting character and word length, with each partition being stored in memory and indexed.
