Trillium Software (a division of Harte-Hanks Data Technologies) is a leader in its field
of "data cleansing" sometimes associated with "data mining." Trillium's data cleansing
software annually saves its customers millions of dollars by helping phone companies,
financial institutions, or mail order houses merge together disparate, mammoth databases
by standardizing fields across databases, extraction of important information buried in
free-form text fields, and removing duplicate records. Intelligence in Trillium can
surmise that "Mary E. Smith" and "M. E. Smith" and "Mary Smith" living at the same
address are the same person and thus eliminate fuzzy duplicates. When Trillium Software
decided to take Trillium to Japan, they called on Basis Technology for its expertise in
Unicode-enablement and cultural/linguistic expertise in Asia.
Trillium is an excellent case study of using Unicode to allow Trillium to process
Japanese data. In this project, we modified an application to process database
information using Unicode as its internal encoding, while allowing for multiple Japanese
legacy encodings on input and output. In the first part of the project, we dealt with
several Unicode-related issues (1) creating mapping tables between Japanese mainframe
vendor encodings and Unicode, (2) ensuring roundtrip convertibility between encodings,
and (3) data storage and sorting. The second half involves creating an all-Unicode
Japanese address and name parser with the intelligence to parse free-form text fields
into the name and address elements. Though the areas covered are specific to Trillium,
issues resolved can also be generalized to other Unicode-enablement situations.
