Improved document annotation techniques are provided. For example, in one aspect of the invention, a technique for determining an annotation for a document includes the following steps/operations. A user-proposed annotation to be associated with the document is obtained. Then, the technique automatically determines, in accordance with a knowledge base, whether the user-proposed annotation matches at least one allowed annotation.

Techniques are provided for enabling execution of a process employing a cache. Method steps can include obtaining a first probability of accessing a given artifact in a state Si, obtaining a second probability of using a predicate from a current state Sc in the state Si, determining a benefit of prefetching the given artifact using the predicate based on at least the first probability and the second probability, and whether and/or when a cache replacement should be conducted, based at least on the benefit determined.

An electrical contact configuration having a test contact point and a contacting element belonging to a testing device for manually touch-contacting the test contact point. The test contact point is a recess, and the contacting element has a contact region producing at least one line contact with the recess.

A method of growing a thin film comprises growing a thin film by conformally forming at least one layer over a substrate having structures extending from a surface of the substrate, whereby the or each layer is formed over the surface of the substrate and over the structures extending from the surface. The thickness of the conformal layer, or the sum of the thicknesses of the conformal layers, is at least half the average spacing of the structures, and; at least one of the height of the structures, the average spacing of the structures and the size of the smallest dimension of the structures is set so as to provide an enhanced growth rate for the or each conformal layer (compared to the growth rate over a planar substrate).

The introduction of extensions to query processing systems for XML documents that allow the analysis of such documents via grouping and aggregation operations. Assumed is the existence of an analysis module for extracting information on how parts of an XML document interrelate with other parts. This information is then used together with a user query in order (1) to partition the nodes of the document in various ways and (2) to compute and output the aggregation value of each such partition. To these ends, there are provided new query operators and extensions to query processing systems comprising a hierarchical node list generator and a hierarchical node list processor. The former takes the grouping information from the query as input and generates document node partitionings. The latter takes the node partitionings as input and computes aggregation values for each partition and generates a query result that is returned to the user.
摘要:
A method of utilizing one or more hints for query processing over a hierarchical tagged data structure having a plurality of nodes in a computing system having memory, the hint being positive if there is a tag accessible in top-down traversal from a child node, and otherwise negative. For each tag in the data structure, the method calculates a bitmap for a current node with all bits set to 1 and for each child node, followed by AND-ing all child bitmaps and setting a bit corresponding to a tag ID of a current tag to zero if such current tag exists. The method further sets a bit of a current tag to 0, calculates a plurality of possible non-redundant hints for each child node, and refreshes a hint list.
摘要:
Methods and systems for analyzing XML documents. The system scans an XML document, identifies different dimensions that span the XML document and detects scoping relationships amongst them. The system uses the dimensional information to create a logical hierarchical scoped dimension analysis model, maps the logical XML tree to this model, and then implements the analytical method over the logical model. The logical model allows both structural features and numeric/non-numeric data to be used for analysis. The analytical method allows users to query irregular structural properties of the XML documents using the XPath navigational API.

Systems and methods of estimating a fluid injector tip temperature. A controller having a processor and a memory supplies a current to a coil of a fluid injector, a resistance of the coil is measured when the current is supplied to the coil, a coil temperature is determined based on the measured resistance, and a tip temperature of a fluid injector tip is estimated based on the determined coil temperature.
