Sun Match Engine Standardization File Types

Several different types of configuration files are included with the Sun Match Engine, each providing specific information to help the engine standardize and match data according to requirements. Several of these files are common to all supported nationalities, but a small subset is specific to each.

• Category Files - The Sun Match Engine uses category files when processing person or business names. These files list common values for certain types of data, such as titles, suffixes, and nicknames for person names or industries and organizations for business names. Category files also define standardized versions of each term or classify the terms into different categories, and some files perform both functions. When processing address files, category files named “clues files” are used.

• Clues Files - The Sun Match Engine uses clues files when processing address data types. These files list general terms used in street address fields, define standardized versions of each term, and classify the terms into various component types using predefined address tokens. These files are used by the standardization engine to determine how to parse a street address into its various components. Clues files provide clues in the form of tokens to help the engine recognize the component type of certain values in the input fields.

• Constants Files - The Sun Match Engine refers to constants files for information about the standardization files, such as the maximum length of the files. For the address data type, the constants file also describes input and output field lengths.

• Patterns Files - The patterns files specify how incoming data should be interpreted for standardization based on the format, or pattern, of the data. These files are used only for processing data contained in free-form text fields that must be parsed prior to matching (such as street address fields or business names). Patterns files list possible input data patterns, which are encoded in the form of tokens. Each token signifies a specific component of the free-form text field. For example, in a street address field, the house number is identified by one token, the street name by another, and so on. Patterns files also define the format of the output fields for each input pattern.

• Key Type Files - For business name processing, the Sun Match Engine refers to a number of key type files for processing information. These files generally define standard versions of terms commonly found in business names and some classify these terms into various components or industries. These files are used by the standardization engine to determine how to parse a business name into its different components and to recognize the component type of certain values in the input fields.

• Reference Files - Reference files define general terms that appear in input fields for each data type. Some reference files define terms to ignore and some define terms that indicate the business name is continuing. For example, in business name processing “and” is defined as a joining term. This helps the standardization engine to recognize that the primary business name in “Martin and Sons, Inc.” is “Martin and Sons” instead of just “Martin”. Reference files can also define characters to be ignored by the standardization engine.
