1. A system for generating a normalized version of a free-formatted data record, said data record being characterized by a plurality of data words, said system comprising a dictionary comprising sequences of data words associated with respective attribute fields corresponding to respective attribute fields defining a normalized data record and associated with respective weight values,means for partitioning said free-formatted record into a plurality of n-word tuples, where n≧

  • 1,means for associating each of said n-word tuples, that compares with a respective one of said sequences, with the associated one of said attribute fields and a respective score value, said score value being derived as a function of the associated one of said weight values, and for identifying for each of said attribute fields the associated n-word tuples having the largest score values, andmeans for forming different combinations from individual ones of the identified n-word tuples and output as said normalized data record that one of said combinations formed from those of said identified n-word tuples having score values which produce the largest sum.
