International Classification:

G06F 17/30

US Classification:

707756, 707769, 707E17014

Abstract:

An adapter receives tuples of streaming data from a streaming data source. The adapter extracts selected attributes from the tuples of streaming data, and writes the selected attributes to a buffer associated with a visualization engine for displaying the selected attributes in a visualization screen. The selected attributes are written to the buffer according to a predefined format supported by the visualization engine. The adapter receives interactive user input to change the selected attributes to be extracted from the tuples and written to the buffer.

International Classification:

G06K 9/46

US Classification:

382190, 382218

Abstract:

A collection of documents are correlated with information items in a fast stream of information using categorical hierarchical neighborhood trees (C-HNTs). First data entities extracted from the documents are inserted into corresponding C-HNTs. The first data entities that are neighbors in the C-HNTs of second data entities extracted from the fast stream items are identified. Similarities between the documents and the fast stream items are determined based on the location at which the neighbors are located.

US Classification:

707822, 707E17005

Abstract:

A sentiment cube system is disclosed. In one example, the system discloses a sentiment storage, including a sentiment cube data structure having a set of cells arranged by a set of dimensions. The system includes a computer programmed with executable instructions which operate a set of modules, wherein the modules comprise: a sentiment storage module which receives sentiment values associated with a set of entity features, and then populates a hierarchy of the cells in the sentiment cube with the sentiment values. A sentiment analysis module effecting a set of operations on the sentiment cube.

International Classification:

G06F 17/30

US Classification:

707722, 707774, 707E17014

Abstract:

A method of evaluating nested complex sequence pattern queries includes obtaining events from an event stream and evaluating the events within a first window using an outer query to produce outer partial results. The method also includes determining a more stringent window constraint, the more stringent window constraint comprising a subset of the window constraint corresponding to events that produces the outer partial results and passing the more stringent window constraint to an inner query nested within the outer query. A complex event processing system is also provided.

US Classification:

707718, 707E17132

Abstract:

There is provided a computer-implemented method of determining an execution ordering. An exemplary method comprises generating a directed graph based on a hierarchy. The hierarchy includes a plurality of pattern queries. The method also includes determining a minimum spanning tree of the directed graph. The method further includes determining an execution order of the pattern queries based on the minimum spanning tree.

US Classification:

701119

Abstract:

A method and system for identifying impact of a traffic incident on a road network, wherein the impact may be measured in terms of a spatial-temporal-impact region, in terms of incident duration from the time the incident is reported to the time at which the affected road network returns to recurrent flow conditions, and in terms of a cumulative time delay of all affected drivers.
