Multi-model fused short text classification method

The invention discloses a multi-model fused short text classification method. The multi-model fused short text classification method comprises a learning method and a classification method. The learning method comprises the following steps: carrying out word segmentation and filtration on short text training data to obtain a word set; calculating the IDF value of each word; calculating the TFIDF values of all the words and constructing a text vector VSM; and carrying out text learning on the basis of a vector space model, and constructing an ontology tree model, a keyword overlapping model, a naive Bayesian model and a support vector machine model. The classification method comprises the following steps: carrying out word segmentation and filtration on a to-be-classified short text; generating a text vector on the basis of the support vector machine model; respectively classifying by using the ontology tree model, the keyword overlapping model, the naive Bayesian model and the support vector machine model to obtain single model classification results; and fusing the single model classification results to obtain a final classification result. According to the method disclosed in the invention, multiple classification modes are fused and the short text classification correctness is improved.

Trusted file relabeler

A trusted relabeler system and software is provided that allows for the simultaneous reclassification of multiple files to multiple classification labels (security domains or computer networks) through automation of the multi-person review process. Roles, used to break down the requirements of the multi-person review process, dictate what specific function a user can perform. There are three roles used: Submitter, Processor, and Reviewer. The Submitter is allowed to submit one or more documents for reclassification, while the Processor is allowed to submit one or more documents for reclassification, perform an initial review and acceptance of the document, and assign a specific Reviewer for the document. The Reviewer is allowed to perform final verification and, upon acceptance, allows the document to be reclassified appropriately. Users are assigned one or more roles and a set of source and destination classification labels inside the security policy of a specific user that are bounded (restricted) by the clearance (maximum classification) assigned to a user on the trusted operating system on which the trusted relabeler system is implemented. The bundled documents to be reclassified are virus scanned, file typed, and searched for “dirty words” indicative of a particular classification level. An integrity seal is generated to verify that the files are not tampered with between processing by the Processor and the Reviewer. Files are upgraded or downgraded only if all processes are completed successfully.

Motion recognition and fatigue detection method and system based on gait information

The invention discloses a motion recognition and fatigue detection method and system based on gait information. The method includes the steps that current gait information of a user is acquired; the current gait information is subjected to data processing, a current motion behavior of the user and multiple classification results about whether the user is currently in a fatigue state or not are recognized according to multiple preset motion recognition and fatigue classification models, and the preset motion recognition and fatigue classification models are generated in the mode that the gait information generated when the user performs multiple motion behaviors in a non-fatigue state and the fatigue state serves as sample data, and the sample data is applied to a voting classification algorithm, based on integrated learning, in machine learning to be trained; the current motion behavior of the user and the final result about whether the user is currently in the fatigue state or not are acquired according to the classification results based on the principle that minorities submit to majorities. By means of the method, the injury risk caused by the user fatigue state under different motions is reduced, and the accuracy of motion recognition and fatigue detection is improved.

System and method for generating target area information of a battlefield using information acquired from multiple classification levels

A system and method for generating target area information. The system comprises a first processor effective to receive first information of a first classification level and a second processor effective to receive second information of a second classification level distinct from the first classification level. A cross domain processor is in communication with the first and second processors. The second processor is effective to receive a request from a requesting entity about a region of interest and interrogate a first sensor regarding the request. The second processor is further effective to receive first information from the first sensor and send the request through the cross domain processor to the first processor. The first processor is effective to interrogate a second sensor regarding the request and receive second information from the second sensor. The first processor is further effective to filter the second information based on the first and second classification levels to produce filtered information and send the filtered information through the cross domain processor to the second processor. The second processor is further effective to integrate the first information and the filtered information to produce integrated information and send the integrated information to the requesting entity.
