Assignee:

Lockheed Martin Corporation - Bethesda MD

International Classification:

G06F 11/00

US Classification:

714 41, 714 37

Abstract:

A system evaluates a data cleansing application.

Appl. No.:

10/308760

Inventors:

Douglas R. Burdick - Ithaca NY, US
Robert J. Szczerba - Endicott NY, US
Joseph H. Visgitus - Endwell NY, US

Assignee:

Lockheed Martin Corporation - Bethesda MD

International Classification:

G06F 17/30

US Classification:

707102, 707 6

Abstract:

A system evaluates a first data cleansing application and a second data cleansing application. The system includes a test data generator, an application execution module, and a results reporting module. The test data generator creates a dirty set of sample data from a clean set of data. The application execution module cleanses the dirty set of sample data. The application execution module utilizes the first data cleansing application to cleanse the dirty set of sample data and create a first cleansed output. The application execution module further utilizes the second data cleansing application to cleanse the dirty set of sample data and create a second cleansed output. The results reporting module evaluates the first and second cleansed output. The results reporting module produces an output of scores and statistics for each of the first and second data cleansing applications.

Appl. No.:

10/308763

Inventors:

Douglas Burdick - Ithaca NY, US
Steven Rostedt - Endwell NY, US
Robert Szczerba - Endicott NY, US

Assignee:

Lockheed Martin Corporation

International Classification:

G06F007/00

US Classification:

707/003000

Abstract:

A system identifies similarities in data. The system includes a collection of records, a plurality of transform functions, and a cell list structure. Each record in the collection represents an entity and has a list of fields. Data is contained in each field. The plurality of transform functions operates upon the data in each field in each record. The plurality of transform functions generates a set of output values for facilitating comparison of the records and determining whether any of the records represent the same entity. The cell list structure is generated from the output values. The cell list structure has a list of cells for each field and a list of pointers to each cell of the list of cells for each output value generated by the plurality of transform functions.

Assignee:

Lockheed Martin Corporation

International Classification:

G06F017/00
G06F007/00

US Classification:

707/101000

Abstract:

A system cleanses data. The system includes an input component, a pre-process component, an automated learning component, and a post-process component. The input component receives a collection of records. The pre-process component formats the collection of records and creates a plan for cleansing the collection of records. The automated learning component performs the plan and modifies the plan based on feedback from intermediate steps within the plan. The post-process evaluation component evaluates the result of the automated learning component. The post-process component determines whether to accept the result or to feed back the result to the automated learning component.

Assignee:

Lockheed Martin Corporation

International Classification:

G06F017/00
G06F007/00

US Classification:

707/102000

Abstract:

A system identifies similar records. The system includes a collection of records, a set of Boolean rules, and a cell list structure. Each record in the collection has a list of fields and data contained in each field. The set of Boolean rules operate upon the data in each field. The cell list structure is generated from the collection of records. The cell list structure has a list of cells for each field and a list of pointers to each cell of the list of cells for each record. The set of Boolean rules identifies the similar records from the cell list structure.

International Classification:

G06F007/00

US Classification:

707/001000

Abstract:

A system represents data during a data cleansing application. The system includes a record collection. Each record in the collection includes a list of fields and data contained in each field. The system further includes a predetermined sequence of operations to be performed on the record collection and a plurality of bit-maps representing the record collection. The system still further includes a partitioned sequence of operations for parallel processing of the bit-maps by a plurality of separate devices.

International Classification:

G06F007/00

US Classification:

707/003000

Abstract:

A system builds an extended dictionary for a data cleansing application. The system includes a record collection. Each record in the collection includes a list of fields and data contained in each field. The system further includes an input dictionary defining predetermined valid values for variants of values in at least one of the fields and a set of rules derived from patterns of the field values. The system still further includes an extended dictionary including the input dictionary and the rules.
