International Classification:

G06F 17/30

US Classification:

707739, 707777, 707796, 707803

Abstract:

One or more classification algorithms are applied to at least one natural language document in order to extract both attributes and values of a given product. Supervised classification algorithms, semi-supervised classification algorithms, unsupervised classification algorithms or combinations of such classification algorithms may be employed for this purpose. The at least one natural language document may be obtained via a public communication network. Two or more attributes (or two or more values) thus identified may be merged to form one or more attribute phrases or value phrases. Once attributes and values have been extracted in this manner, association or linking operations may be performed to establish attribute-value pairs that are descriptive of the product. In a presently preferred embodiment, an (unsupervised) algorithm is used to generate seed attributes and values which can then support a supervised or semi-supervised classification algorithm.

Yan Liu - Elmsford NY, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 17/30

US Classification:

707706, 707707, 707708, 707709, 707723, 707748, 707749, 707750, 707751, 707753

Abstract:

A method and system for identifying nodes with similar content. In one aspect, the method comprises determining a structure of a network of nodes, said structure defined by incoming links and outgoing links between nodes within said network, grouping said nodes within said network into a first set of modules, calculating a first modularity value between each of the modules within the first set, said modularity value indicating a degree of similar content within each module, calculating a topical relevance value for each of the modules, selecting those modules whose topical relevance value exceeds a threshold value and calculating an authority score for the selected modules.

International Classification:

H01L 21/683

Abstract:

Electrostatic chucks include multiple electrodes, each having a spiral shape surrounding a center of a surface of the electrostatic chuck, to provide a polyphase electrostatic chuck. Each electrode can be connected to a different phase of power. The spiral shapes can each avoid one another as well as avoiding holes or openings in the surface of the electrostatic chuck. The spiral shapes can be algorithmically determined using a processor. These electrostatic chucks can include three or more electrodes. Methods of manufacture of the electrostatic chucks include determining shapes for each of the electrodes and providing each of the electrodes.
