Methods and apparatus for integrating relational and hierarchical data, schema definitions, and queries in a data processing system are provided. It is determined if one or more schema definitions or one or more query expressions are provided as input to the data processing system. The one or more schema definitions are converted into an intermediate schema language component of an intermediate data language when one or more schema definitions are provided. The one or more query expressions are converted into an intermediate query language component of the intermediate data language when one or more query expressions are provided. The intermediate schema language component or the intermediate query language component is compiled in an intermediate data language processing engine into a run-time representation in accordance with a relational-hierarchical analysis.

The invention discloses a malicious encrypted flow feature analysis method, which belongs to the crossing field of network security and machine learning, and is used for analyzing the HTTPS flow and detecting the malicious threats in the HTTPS flow. The method comprises the following steps of modeling the flow data by taking a connection quaternion as a data structure, analyzing the encrypted flowfrom four levels by taking the connection quaternion as a unit, and extracting the flow-level features, TLS handshake features, X.509 certificate features and context features of the connection quaternion to obtain an initial feature set, adopting a recursive feature elimination method based on a decision tree to screen the initial feature set to obtain an optimal feature set used for the machinelearning model training to thereby obtain a malicious encrypted flow detection model.

A graphic user interface facilitates the hierarchical analysis of timing parameters related to network-based applications. At the top level of the hierarchy, the user is presented a summary of the delays incurred while running an application, or while simulating the running of an application, organized by delay categories, including processing delays at each node, as well as propagation delays at each link between nodes. The interface enables a user to “drill down” into lower levels of the timing information hierarchy by ‘clicking’ on currently displayed information. The information is presented in a form most appropriate to the level of analysis. The presentation forms include, for example, pie-charts, multi-variable timing diagrams (in both absolute and relative forms), data exchange charts, and so on, and ‘zoom’ capabilities are provided as appropriate to the particular display form.

The invention relates to a vehicle information extraction method and s system thereof. The input of the system is a picture shot by an existing bayonet system. Through the pretreatment methods of the adjustment of a contrast range and de-noising processing, a hierarchical analysis method is employed, a plurality of areas comprising vehicles in the picture and the corresponding vehicle type information and vehicle color information, for a passenger car area, the brand and specific model of the car are calculated through a unified vehicle type recognition model, and vehicle license plate information is extracted for passenger car and large vehicle areas. Through the system, the vehicle type, brand and specific model of a vehicle in the picture can be analyzed in a 100-millisecond level.

A computer implemented method of producing macro-view conclusion data related to a seismic event. The method includes receiving at a processing center a set of data related to a parameter of a seismic event. The parameter is measured using a vibration sensor of a hard disk drive of a computer at a known, fixed location, wherein the vibration sensor produces the set of data. The method further includes processing the set of data at the processing center to produce the macro-view conclusion data. The macro-view conclusion data is then stored in a storage device.

The invention provides an analytic hierarchy process based heterogeneous wireless network selection method. The method is characterized in that a proper network is selected according to the requirements of different services on the network performance; meanwhile, different network determining results are provided according to the requirement of a user on the network and different network cost and benefits of the user, so that the user can be satisfied to the maximum. The method comprises the steps of analyzing the usability property of the candidate networks to create an analytic hierarchy structural model; creating a determining matrix for describing the relative importance degree of the properties according to the requirements of different services on the network performances; selecting two secondary determining matrixes from the determining matrixes according to the cost and benefit property parameters; performing the analytic hierarchy process to obtain network advantages and disadvantages sequence result; providing the final network determining result according to the interests of the user to the network cost and benefits; selecting the most proper network as the switching target network.

A method and apparatus for partitioning of the input design into repeating patterns called template cores for the application of reticle enhancement methods, design verification for manufacturability and design corrections for optical and process effects is accomplished by hierarchy analysis to extract cell overlap information. Also hierarchy analysis is performed to extract hierarchy statistics. Finally template core candidates are identified. This allows to the design to be made amenable for design corrections or other analyses or modifications that are able to leverage the hierarchy of the design since the cell hierarchy could otherwise be very deep or cells could have significant overlap with each other.

The invention relates to a data processing method and device for a customer service staff scoring system. The method includes the following steps that: a plurality of key indexes are automatically identified and analyzed from a large number of preset evaluation indexes based on a sparse regularization model; the weights of the plurality of key indexes relative to customer service scoring can be determined through adopting an analytic hierarchy process; and the comprehensive score of customer service staff is calculated according to the weights of the plurality of key indexes and the actual index values of the key indexes. Compared with the prior art, and according the method of the invention, the coefficient regularization method and the analytic hierarchy process are combined together, and therefore, scoring on the customer service staff can be realized automatically, and the workload of scoring personnel can be decreased, and work efficiency can be improved.
