A document image that is the source of Optical Character Recognition (OCR) output is displayed. Recognition confidence parameters are determined for regions of the document image corresponding to words in the OCR output. The regions are displayed in a manner (e.g., highlighted in various colors) that is indicative of the respective recognition confidence parameter. Preferably, a user can select a region of the displayed document image. When the region is selected, text of the OCR output corresponding to the selected region is displayed in a pop-up menu.

Method and apparatus for displaying regions in a document image having a low recognition confidence

The present invention is a computer system for modifying a database which comprises a computer that modifies records stored in a database. In the process for modifying records in the database, addresses to memory locations in a disk storage unit are accessed during the commit phase by first checking the address space in a transaction log. The computer system of the present invention operates by committing transactions without locking out readers. This is possible because any changed data in the database is reflected in the transaction log and the log must be accessed prior to reading from the disk storage unit. As a result, the user sees changed data when the log is accessed, or if data has not been changed, the log merely directs the computer to the address in the original database storage where unchanged data is stored.

System for modifying a database using a transaction log

Document texts are produced by recognizing characters in document images by an Optical Character Recognition (OCR) process. When such a document text matches one or more search terms of a query, the corresponding document image is displayed. Regions of the document image, corresponding to words of the document text that match the search terms, are displayed in a visually distinctive manner. The display of the document image may be augmented by displaying a region corresponding to a reference text within the document text in another visually distinctive manner.

Methodology for displaying search results using character recognition

The system of the present invention provides for a method and apparatus of displaying portions of text from multiple documents over multiple databases related to a search query. The initial step in this method is to identify a search query. Based on this identification, a search against multiple databases is initiated. In particular, the computer system identifies auxiliary databases either within a network or between networks that are likely to contain documents relating to terms in the search query. Upon identification of these databases, the databases are then searched to identify those documents relating to the identified query. The various sets of identified documents from multiple databases are then returned and processed to create an ordered ranking for the returned documents. Text portions from the highest ranking documents across the multiple databases are then automatically displayed to the user.
