A transcription error is a specific type of data entry error that is commonly made by human operators or by optical character recognition programs (OCR).

Text joins for data cleansing and integration in a relational database management system

An organization's data records are often noisy: because of transcription errors, incomplete information, and lack of standard formats for textual data. A fundamental task during data cleansing and integration is matching strings—perhaps across multiple relations—that refer to the same entity (e.g., organization name or address). Furthermore, it is desirable to perform this matching within an RDBMS, which is where the data is likely to reside. In this paper, We adapt the widely used and established cosine similarity metric from the information retrieval field to the relational database context in order to identify potential string matches across relations. We then use this similarity metric to characterize this key aspect of data cleansing and integration as a join between relations on textual attributes, where the similarity of matches exceeds a specified threshold. Computing an exact answer to the text join can be expensive. For query processing efficiency, we propose an approximate, sampling-based approach to the join problem that can be easily and efficiently executed in a standard, unmodified RDBMS. Therefore the present invention includes a system for string matching across multiple relations in a relational database management system comprising generating a set of strings from a set of characters, decomposing each string into a subset of tokens, establishing at least two relations within the strings, establishing a similarity threshold for the relations, sampling the at least two relations, correlating the relations for the similarity threshold and returning all of the tokens which meet the criteria of the similarity threshold.

Method of detecting data entry errors by sorting amounts and verifying amount order

InactiveUS6055327AReduction of correction keying laborLabor for correctingCharacter and pattern recognitionPattern recognitionAmbiguity
An improved method and system for verifying the correctness of data entered from document images. Images are sorted according to their entered values, and are then presented to an adjudication operator, who verifies that the values shown in the images are correctly ordered. Images violating the sorted order are marked for correction. The marking of images is ergonomically advantageous in requiring only a simple pointing device used infrequently. Input can be by voice command. In one preferred embodiment, images are presented in rows and columns upon a video screen, and the operator uses controls similar to the "forward" and "back" buttons of a web browser to navigate through a set of images. In another preferred embodiment, images scroll automatically upwards through an attention zone, within which the operator verifies correct pairwise ordering. The adjudication method can operate with or without information used in previous systems, such as target values, recognition confidence, balancing information, and the like. Variants are described using such information to disambiguate mis-ordered pairs of images; to select images to participate in amount order adjudication; to determine when to accept a second-choice recognition result; and to bypass initial data entry altogether. The method provides for non-intrusive monitoring of its own performance and of the accuracy of the initial data entry module, by measuring results on items whose ordering has been intentionally manipulated.

Patent management devices for applicants and firms

The invention provides a patent management device for applicants. The device comprises a data receiving unit, a data analyzing unit and a match writing unit. The data receiving unit is used for receiving original data from a firm through a predetermined data path, and the original data at least includes parts of data consistent with electronic application interface specification. The data analyzing unit is used for analyzing the original data according to the electronic application interface specification and acquiring at least one item of patent attribute information from the original information, and the patent attribute information includes at least one predetermined patent application identifier. The match writing unit is used for finding corresponding patent table entries in a database according to the patent application identifier, and storing the patent attribute information into the patent table entries. The invention further provides a corresponding patent management device for firms. The patent management devices for applicants and firms are matched to realize that data can be stored in an enterprise database automatically, procedure labor investment is reduced greatly, and meanwhile, the problem that manual data entry error probability is high is avoided.
