Method for searching Web services according to non-functional requirements of user

ActiveCN102193994AEliminate subjective differencesEliminate differences in environmental conditionsSpecial data processing applicationsNon functionalNon-functional requirement
The invention relates to the technical field of software engineering, in particular relating to a method for searching Web services according to non-functional requirements of a user. The method comprises the following steps: processing a requirement text of the user, and extracting key words from the requirement text; using a noumenon to perform semantic disambiguation on the got key words; identifying the key words representing the non-functional requirements of the user, and mapping the key words to corresponding Web service quality attributes; collecting data of the quantity attributes tobe analyzed in the candidate Web services one by one, and using the cloud transform method to get a corresponding atomic concept set; transforming the got atomic concept set to a corresponding candidate concept set with appropriate grain size one by one; and selecting one concept which is most matched with the key words representing the non-functional requirements of the user from each of the sets respectively, and generating combined constraint conditions for inquiry according to a corresponding cloud model. By utilizing the qualitative and quantitative conversion of the cloud model, the impacts of subjective differences of experts and differences in environmental conditions on the inquiry are reduced, and a result which is closer to expectation of the user is returned.

Interaction control method and device of intelligent blackboard, intelligent blackboard and storage medium

The embodiment of the invention discloses an interaction control method and device of an intelligent blackboard, the intelligent blackboard and a storage medium, and relates to the field of intelligent blackboards. The intelligent blackboard comprises a touch module, at least one first blackboard area and at least one second blackboard area, wherein a display screen is installed in the first blackboard area, and the touch module is used for detecting touch operation for the first blackboard area and the second blackboard area. The method comprises the steps: receiving the first touch operationfor the second blackboard area; when the first touch operation is a writing operation, displaying a touch track corresponding to the writing operation in the display screen; when the first touch operation is a non-writing operation, responding according to a response strategy of the non-writing operation, and displaying a display picture corresponding to the non-writing operation in the display screen. By the adoption of the method, the technical problem that data interaction cannot be conducted between a traditional blackboard and electronic equipment in an intelligent blackboard in the prior art can be solved.

Evaluation system for transient stability of large-scale power system based on optimal mutual information redundancy

The invention discloses an evaluation system for transient stability of a large-scale power system based on optimal mutual information redundancy. The system firstly obtains a power system large dataset that can approximately represent all operating characteristics of a current power system based on PMU data or software simulation; on the basis, an optimal characteristic set with maximum correlation and minimum redundancy with transient stability margin of the system is constructed through multi-time utilization of an information redundancy optimization algorithm; a function expression of a relationship between a selected variable and TSM is constructed by utilizing MATLAB; and the TSM can be directly estimated by an expression through real-time variable data obtained by the power system,after appropriate compensation is performed on a result, the result is fed back to on-site scheduling personnel in order to make timely decisions. The system can solve the shortcomings that traditional evaluation methods are poor in precision, are slow in speed, are poor in robustness of data loss, are poor in evaluation analyticity, and the like, and effectively meets real-time evaluation requirements of large-scale power systems.

Image classifying method and device, electronic equipment and computer readable storage medium

The invention relates to an image classifying method and device, electronic equipment and a computer readable storage medium. The method comprises the steps of obtaining a first-level human face whichsatisfies a preset condition from images according to the size of the area of the human face, and conducting human face identification on the first-level human face to obtain the human face type corresponding to the first-level human face; then obtaining a second-level human face in the images, and then conducting human face identification on the second-level human face to obtain the human face type corresponding to the second-level human face, wherein the second-level human face is the human face except the first-level human face in the images; finally, classifying the images into corresponding human face types according to the human face type corresponding to the first-level human face and the human face type corresponding to the second-level human face. The human face types obtained inthis way can be accurate, a large quantity of unimportant human face types cannot be generated, and the effectiveness of the classification result is improved, which better meets actual requirementsof a user. Finally, the images are classified into the corresponding human face types.

Mouse control method and application thereof

The invention provides a mouse control method and application thereof, and the method comprises the steps: building a selection table P of an initial DPI value of a mouse, recognizing the type of a real-time program D0, responding to the mouse in real time, on a host, selecting a DPI value matched with the type of the program from the selection table P, and setting the DPI value as the initial DPI value of the mouse. According to the method, the mouse DPI values can be primarily selected according to the program types, the selection efficiency is high, the calculation amount can be remarkably reduced, and the primarily selected mouse DPI values which are relatively adaptive can be provided for different types of programs. After primary selection, the mouse DPI value is adjusted for the first time and more than one time of subsequent adjustment to complete adjustment of the mouse DPI value, so that the mouse DPI value can be further matched with a corresponding program type, and compared with the method of selecting the DPI value by adopting an optimal iteration algorithm and the like in the prior art, the calculation amount can be remarkably reduced, the workload of a host is reduced, and crash of the host or occupation of a large number of computing resources is avoided, and the adjustment duration is short.
