Abstract: The present invention uses a segmented caching data structure to cache database objects provided by a database server. The database server provides database objects in response to requests by a number of different programs. The segmented caching data structure is made up of a single central cache and a number of program caches, each corresponding to one of the programs. When a database object is provided by the database server in response to a request by any of the programs, a copy of the database object is stored in the central cache. Another copy of the object is stored in the program cache for the program that requested the database object. When the segmented caching data structure is maintained in this manner, when a request is made by one of the programs a copy of the requested object stored in either of the central cache or the program cache for the program may be used, making it unnecessary for the database server to provide the requested database object.

Abstract: An information retrieval system generates query feedback terminology for an input query based on a corpus of documents and the input query. Potential query feedback terms are identified through the corpus of documents for use as query feedback in the information retrieval system. To process a query, which includes at least one query term, co-occurrence signatures for “N” query feedback terms are generated. An N×N matrix of the co-occurrence signatures depict patterns of semantic distance and conceptual proximity among the “N” query feedback terms. The N×N matrix is processed to reduce the number of the entries in the signature to an N×M matrix while preserving the co-occurrence distance characteristics among the signatures. Query feedback terms with co-occurrence signatures, which compare with co-occurrence signatures of the query term in a predetermined manner, are selected as query feedback.

Abstract: Frame-based heroic data recovery on data retrieved from mass storage in which identifiable blocks have been detected to be corrupt. Logical sets of blocks are configured into frames. The invention becomes operable when standard data recovery techniques such as Error Correction Code (“ECC”), working on a frame-by-frame basis, are unable to recover all the corrupt data within the frame because there are just too many corrupt data blocks. The invention then sequentially applies a preselected series of heroic techniques, each heroic technique in the series applied concurrently to all blocks in the frame. The invention combines the corrective effects of the individual applications of heroic techniques in the series, until sufficient individual data blocks overall in the frame are recovered to allow standard frame-based recovery techniques such as ECC to complete the job.

Abstract: A technique for implementing in a networked client-server environment, e.g., the Internet, network-distributed advertising in which advertisements are downloaded, from an advertising server to a browser executing at a client computer, in a manner transparent to a user situated at the browser, and subsequently displayed, by that browser on an interstitial basis, in response to a click-stream generated by the user to move from one web page to the next. Specifically, an HTML advertising tag is embedded into a referring web page. This tag contains two components. One component effectively downloads, from a distribution web server and to an extent necessary, and then persistently instantiates an agent at the client browser. The other component is a reference, in terms of a web address, of the advertising management system. The ad management system selects the given advertisement that is to be downloaded, rather than having that selection or its content being embedded in the web content page.

Abstract: The imaging system that is described below is an image streaming system which is different from traditional compression systems. It eliminates the necessity to store a compressed version of the original image, by streaming ROI data using the original stored image. The imaging system of the present invention also avoids the computationally intensive task of compression of the full image. Instead, once a user wishes to interact with a remote image, the imaging server performs a fast preprocessing step in near real time after which it can respond to any ROI requests also in near real time. When a ROI request arrives at the server, a sophisticated progressive image encoding algorithm is performed, but not for the full image. Instead, the encoding algorithm is performed only for the ROI.
