Understanding the Sun Match Engine

The Address Clues File (addressClueAbbrev*.dat)

The address clues file lists common terms in street addresses, specifies a normalized value for each common term, and categorizes the terms into street address component types. A term can be categorized into multiple component types. The relevance value specifies which of the component types the term is most likely to be. For example, the term “Junction” is standardized as “Jct”, and is classified as a street type, building unit, and generic term (giving relevance in that order).

This file helps the Sun Match Engine recognize common terms in street addresses, and to parse and normalize the values correctly. The syntax of this file is:

common-term normalized-term ID-number/type-token

You can modify or add entries in this table as needed. Table 16 describes the columns in the addressClueAbbrev*.dat file.

Table 16 Address Clues File Columns

Column 

Description 

common-term

A term commonly found in street addresses. 

normalized-term 

The normalized version of the common term. 

ID-number/type-token 

An ID number and a token indicating the type of address component represented by the common term. The ID number corresponds to an ID number in the address master clues file, and the type token corresponds to the type specified for that ID number in the address master clues file. One term might have several ID number and token type pairs.
