摘要:
Described is a method and apparatus for obtaining accurate, timely information for event detection and prediction based on autonomous opportunism. The objective is to make the best possible use of all available resources at the time of acquisition, including historical data, multiple sensors, and multiresolution acquisition capabilities, under a given set of processing and communication bandwidth constraints. This method (and the corresponding apparatus) fuses multiple adaptively acquired data sources to prepare information for use by decision support models. The onboard data acquisition schedule is constructed to maximize the prediction accuracy of the decision models, which are designed to operate progressively, utilizing data representations consisting of multiple abstraction levels and multiple resolutions. Due to the progressive nature of these models, they can be executed onboard even with the use of substantially summarized (or compressed) datasets delivered from the ground or from other satellite platforms. Models are formulated to accept data with less than complete certainty, thus allowing real-time decisions to be made on locations where additional data is to be acquired based on predicted likelihood of the event of interest and uncertainties. Multi-abstraction-level multi-resolution data is expressed using standard-compliant representations, and progressively transmitted to the ground or other platforms. More detailed calculations can then be performed on the ground using all of the available real time and historical data.

The invention provides a next generation decision support system that includes highly adaptive sensors, transport, and models to enable time critical decision making. The decision support model of the system is progressive so that not all input parameters need to be available to produce model prediction output. Input parameters of the model with the largest first order derivative values are given highest priority in data acquisition and transmission. The parameters acquired at the sensors are stored in progressive data representation formats, which later on are progressively transmitted to the decision support server. Progressive data representation, progressive transmission, and progressive model are thus three key elements that need to be integrated together. The present invention presents a method and an apparatus that form an optimized process including the three elements subject to the decision making utility function.

Methods and apparatus for providing a multi-tier object-relational database architecture are disclosed. In one illustrative embodiment of the present invention, a multi-tier database architecture comprises an object-relational database engine as a top tier, one or more domain-specific extension modules as a bottom tier, and one or more universal extension modules as a middle tier. The individual extension modules of the bottom tier operationally connect with the one or more universal extension modules which, themselves, operationally connect with the database engine. The domain-specific extension modules preferably provide such functions as search, index, and retrieval services of images, video, audio, time series, web pages, text, XML, spatial data, etc. The domain-specific extension modules may include one or more IBM DB2 extenders, Oracle data cartridges and/or Informix datablades, although other domain-specific extension modules may be used.

Systems and methods for describing image content establish image description records which include an object set (24), an object hierarchy (26) and entity relation graphs (28). For image content, image objects can include global objects (O0 8) and local objects (O1 2 and O2 6). The image objects are further defined by a number of features of different classes (36, 38 and 40), which in turn are further defined by a number of feature descriptors. The relationships between and among the objects in the object set are defined by the object hierarchy (26) and entity relation graphs (28). The image description records provide a standard vehicle for describing the content and context of image information for subsequent access and processing by computer applications such as search engines, filters, and archive systems.

A computer-based technique is provided for retrieving one or more items from a database in response to a query specified by a user via one or more example sets. Preferably the example sets include multiple positive and negative example sets. The method comprises the following steps. First, a scoring function is constructed from the one or more example sets. The scoring function gives higher scores to database items that are more closely related to the query than to database items that are not as closely related to the query. The scoring function is operable for use with a multidimensional indexing structure associated with the database. Then, the one or more database items that have the highest score as computed using the scoring function are retrieved via the multidimensional indexing structure.

Under the present invention, an illustrative feature is to provide a method and system/structure for remotely controlling multiple computer systems by interacting with GUIs. Specifically, the present invention allows a controlled computer/system to be remotely controlled via a controlling computer/system. To this extent, data/action capture instrumentation is provided on the controlling system for automatically creating a representation of content of the GUI of the controlling system, for automatically observing a set of actions performed by a user on the GUI of the controlling system, for automatically creating a representation of the observed actions, and for sending to the controlled system the representation of the observed actions. In addition, execution instrumentation is provided on the controlled system for receiving the representation and replicating the actions on the controlled system by interacting with a GUI of the controlled system.

As indicated above, an exemplary feature of the present invention is to automatically identify corresponding GUI elements on different computer systems, or the same computer system at different points in time. Specifically, under the present invention, a user action on a widget of a GUI provided by an application loaded a first computer system is observed, and information about the widget(s) involved in the user action as well as on all other widget(s) in the GUI is collected and associated with the user action. Thereafter a widget(s) (on which the user action is to be performed) of a GUI provided by the application as loaded on a second computer system is robustly identified using the collection information. Then, the action is performed on the identified widget(s). In identifying the widget(s), the present invention utilizes a set of hard and soft constraints to identify a matching widget(s).

Access is obtained to a plurality of intermediately transformed electronic documents (with a plurality of sections and subsections) which have been transformed, by topical analysis and text summarization techniques, from a plurality of original electronic documents comprising at least some unstructured electronic documents. Audit and retrieval agent code is appended to the sections and subsections to create a plurality of finally transformed electronic documents. Users are allowed to access the finally transformed electronic documents. The users are provided with accountability reminders contemporaneous with the access. The access of the users to the sections and subsections of the finally transformed electronic documents is logged. An audit report is provided based on the logging. Also provided is a cloud service for enterprise-level sensitive data protection with variable data granularity, using one or more one guest virtual machine images.

A method, system and computer program product for facilitating creation of a presentation by a user. In one embodiment, an input unit is configured to receive a target outline for a target presentation. An outline unit is configured to generate context-sensitive queries based, in part, on the hierarchical relationships of the outline topics in the target presentation. A search unit is configured to search a presentation repository using the context-sensitive queries for matching presentation slides that are relevant to the outline topics of the target presentation. An output unit is configured to present the matching presentation slides for evaluation by the user.
