An electronic search is automatically initiated when a cursor hovers in one location for a predetermined time. A target process associated with a target window is forced to re-render data to the target window in an update region that includes the detected cursor location. From the re-rendered data, a primary word and context words near the cursor location are determined. One or more local or remote electronic data stores are searched for substantive content related to the words. The content is prioritized according to user preference and displayed in a semitransparent window that is persistently visible to a user, yet does not obscure other content in an underlying window and does not shift the focus from an active window. Re-rendering is accomplished by invalidating an update region of the target window, and forcing the operating system to issue a paint message, causing the target process to redraw the update region.

One embodiment of the present invention provides a system for facilitating use of a collation element that supports a large number of characters. The system operates by receiving the collation element and reading a primary weight value from a primary weight field within the collation element. If the primary weight value falls within a reserved set of values, the system reads an additional portion of the primary weight value from both a secondary weight field and a tertiary weight field within the collation element. On the other hand, if the primary weight value is not within the reserved set of values, the system reads a secondary weight value from the secondary weight field, and also reads a tertiary weight value from the tertiary weight field.

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.

A system and method for communicating information in a wireless cooperative relay network of nodes, the nodes including a source, a set of relays, and a destination. The source broadcasts a code word encoded as a data stream using a rateless code. The relays receive the data stream, decode the data stream to recover the code word, and reencode and transmit the recovered code word as the data stream with the rateless code. The destination receives and decodes the reencoded data streams to recover the code word.

The present invention relates to a disc array apparatus assuring that even if contradiction is detected in matching of parity data during a read parity check, correct host data is Restructured and can always be transferred to the host. The disc array apparatus of the present invention is particularly applicable to disc drives in the RAID configuration. For example, in a disc array apparatus of the present invention implementing RAID level 3, the disc array apparatus adds CRC data to data transferred from a host computer, divides the data, generates parity from the divided data, and stores the data and the parity data into the disc drives. During a read operation, the disc array apparatus of the present invention executes a read parity check. If contradiction is detected between the parity data stored in the disc drives and the parity data generated during the read parity check, the disc array controller sequentially assumes, one disc drive at a time, that one of the disc drives is storing erroneous data, restructures the host data from the divided data and parity data of the disc drives other than the disc drive storing erroneous data for each assumption, and executes a CRC check on the restructured host data for each assumption. Restructured host data is determined to be correct host data when the CRC check detects no error. The principle of the present invention is also implemented in other RAID levels, and using data such as time or counter value, to determine and restructure erroneous data.

A processor includes first and second execution cores that operate in a redundant (FRC) mode, an FRC check unit to compare results from the first and second execution cores, and an error check unit to detect recoverable errors in the first and second cores. The error detector disables the FRC checker, responsive to detection of a recoverable error. A multi-mode embodiment of the processor implements a multi-core mode in addition to the FRC mode. An arbitration unit regulates access to resources shared by the first and second execution cores in multi-core mode. The FRC checker is located proximate to the arbitration unit in the multi-mode embodiment.

The amount of work processing (main processing amount) of a database is acquired and accumulated. A value (main processing index) indicating the transition of the amount of main processing amount available in a time frame that is presumed to be required for backup is calculated by using the amounts of main processing accumulated during the latest period of time. The main processing index is compared with the backup executability reference value which is a threshold value determining the backup executability. If the main processing index is smaller than the threshold value, backup is executed. If the main processing index is larger than the threshold value, backup is not executed but the amount of main processing is again acquired to calculate the main processing index, and the main processing index is compared with the backup executability reference value.
