  • Publication number: 20200118653
    Abstract: A method, system and computer program product for ensuring quality in electronic health data. Data processing pipelines among different tenants are monitored for data artifacts generated from electronic health data, where a “data artifact” refers to the tangible by-products produced during the processing of the electronic health record datasets generated by the electronic health record systems as well as the datasets themselves. Out of the generated data artifacts, those data artifacts that are produced from the same stage of the data processing pipelines among the different tenants are aggregated. A set of metrics at various levels of a dataset hierarchy are produced from the aggregated data artifacts. Such metrics provide information about a quality of the electronic health data. A quality report, which may include flagged issues with the datasets, is then generated and presented to a user based on an analysis of the produced set of metrics.

  • Publication number: 20180232344
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for determining summary content for resources in a domain. In one aspect, a method includes accessing a first resource belonging to a particular domain, selecting an anchor in the first resource linking to a second resource belonging to the particular domain, identifying particular text content in the first resource that is subordinate to the anchor that the second resource includes the particular text content that is subordinate to the anchor, based on determining that the second resource includes the particular text content that is subordinate to the anchor, generating a domain template for the particular domain, the domain template specifying a location of the particular text content in the second resource, and determining, for each respective resource belonging to the particular domain having a structure matching the domain template, respective text content for the respective resource.

  • Patent number: 9753901
    Abstract: Systems and techniques are provided for detecting columns of an electronic page based on a render of the electronic page and identification of one or more columns based on the render. A column of interest may be identified based on detecting the one or more columns based on a physical position of the column, a column size, and/or the content within the column. The column of interest may be used to index or categorize the electronic page as the most relevant information corresponding to the page may be contained in the column of interest.

  • Publication number: 20150322873
    Abstract: A fuel-saving self-adjusting system for a vehicle engine adapted to the actual conditions of a road, including an information center and a plurality of onboard computers respectively mounted on a plurality of vehicles. Each of the onboard computers has a vehicle controlling module for adjusting a response of the engine of each vehicle so as to reduce adverse influences of improper driving manners. An optimized standard road resistance characteristic coefficient is applied as a more reliable reference to reduce the fuel consumption of the vehicle efficiently.

  • Patent number: 9080669
    Abstract: A system and method of selecting optimum gear of automobile is provided. The system includes a data processor; a running vehicle data collection module; an output module; and a memory. The memory is stored with universal characteristic curve of an engine, gear ratios of a gearbox, speed reduction ratios, and a tire radius. The running vehicle data collection module collects and sends a current vehicle speed, revolutions of the engine, and an output torque of the engine to the data processor. The data processor processes the universal characteristic curve of the engine, the gear ratios of the gearbox, the speed reduction ratios, and the tire radius to determine a current gear and an optimum gear. The data processor outputs the optimum gear to the output module if the current gear is not the optimum gear. The system can select optimum gear in real time and lower fuel consumption.
