|Understanding the Oracle Java CAPS Match Engine Java CAPS Documentation|
The standardization configuration files define additional logic used by the Oracle Java CAPS Match Engine to standardize specific data types. This logic helps define how fields in incoming records are parsed, standardized, and classified for processing. Standardization files include data patterns files, category files, clues files, key type tables, constants files, and reference files.
The standardization configuration files are stored in the master index project and appear as nodes in the Standardization Engine node of the project. Several standardization files are common to all implementations of the Oracle Java CAPS Match Engine, but each national domain uses a subset of unique files. The common files are listed directly under the Standardization Engine node of the master index project; the files unique to each national domain are listed in individual sub-folders under the Standardization Engine node.
The standardization configuration files for the Oracle Java CAPS Match Engine must follow certain rules for formatting and interdependencies. The following topics provide an overview of the types of configuration files provided for standardization.
Several different types of configuration files are included with the Oracle Java CAPS 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 Oracle Java CAPS 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 Oracle Java CAPS 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 Oracle Java CAPS 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 Oracle Java CAPS 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.
By default, the Oracle Java CAPS Match Engine supports addresses and names originating from Australia, France, Great Britain, and the United States. Each national domain uses a set of common standardization files and a smaller set of unique, domain-specific files to account for international differences in address formats, names, and so on. You can process with your data using the standardization files for a single domain or you can use multiple domains depending on how the Match Field file is configured.
