A method, system, and computer program product to make query processing more robust in the face of optimization errors. The invention validates the statistics and assumptions used for compiling a query as the query is executed and, when necessary, progressively re-optimizes the query in mid-execution based on the knowledge learned during its partial execution. The invention selectively places a number of CHECK operators in a query execution plan to validate the optimizer's cardinality estimates against actual cardinalities. Errors beyond a threshold trigger re-optimization, and the optimizer decides whether the old plan is still optimal and whether to re-use previously computed results. The invention addresses arbitrary SQL queries whose plans can contain sub-queries, updates, trigger checking, and view maintenance operations. The invention can handle concurrent update transactions or updates of common sub-expressions in a query execution plan without compromising consistency and isolation as locking information is tied to the record ID.

A procedure for clustering documents that operates in high dimensions, processes tens of thousands of documents and groups them into several thousand clusters or, by varying a single parameter, into a few dozen clusters. The procedure is specified in two parts: computing a similarity score representing the k most similar documents (typically the top ten) for each document in the collection, and grouping the documents into clusters using the similarly scores.

A display method and apparatus for navigation system enables a user to quickly view zoomed images by using a radial scaling method. The display method includes the steps of: reading out map data from a map data storage for displaying a map image on a screen of a navigation system; converting the map data to screen coordinates so that an intended map image is displayed on a correct position on the screen; zooming the map image by enlarging or shrinking distances of points on the map image relative to a center of the screen; and storing the map data converted to the screen coordinates in a memory for use with a further operation of changing the map scale.

Empirically derived models are used to relate user perception to objectively measurable characteristics, under a criterion of nearly perfect co-variance between predicted MOS values and the variations in the values of the objectively measurable characteristics. In the example context of evaluating packet switched telephony service, the present invention eliminates the need to perform subjective tests to characterize each combination of codec type and transmission protocol.

Jigsaw connector pieces representing tasks to be performed are displayed on a computer screen, preferably hierarchically in a tree, to elucidate the relationships between tasks. To perform a task, a user positions an attachment jigsaw piece next to its corresponding connector piece. The user is then prompted to input or verify preferences in a properties panel. For example, a printer may be installed by interconnecting an attachment piece (corresponding to the printer to be installed) next to the printer connector piece in the tree. The user may be aided in the process of matching connector and attachment pieces through the use of matching colors and images on the pieces.
