  • Patent number: 10860849
    Abstract: A method, electronic device and computer program product for categorizing a document that includes determining a key words associated with a document category and corresponding weight. The method also includes determining a score of the document with respect to the key word at least based on frequencies of the key word appearing in a field of the document and the weight and determining that the document is in the document category in response to the score of the document being higher than a threshold.

  • Publication number: 20200371771
    Abstract: An apparatus for upgrading a software product is provided. The apparatus generates an upgrade package of the software product, the upgrade package including an installation file of the software product, a metadata file and one or more executable files. The apparatus also executes the one or more executable files to perform operations for upgrading the software product. The operations include unpacking the installation file; adding a disk file in the installation file to a virtual machine based on a file name indicated in the metadata file, the disk file including upgraded files of the software product; mounting the disk file to a mount point of the virtual machine, wherein the mount point is indicated in the metadata file; and providing a path to access the upgraded files based on the mount point and a folder path of the upgraded files indicated in the metadata file.

  • Publication number: 20200341853
    Abstract: An apparatus, method, and system for indexing backed up files is disclosed. The operations comprise: maintaining a File index and a Backup index, the File index comprising entries each associated with an individual file backed up, the Backup index comprising entries each associated with a particular backup; receiving a request to determine whether or not a first file is included in a first backup; determining whether or not the first file is included in the first backup based on the File index entry corresponding to the first file and the Backup index entry corresponding to the first backup; and returning a result of the determination of whether or not the first file is included in the first backup.

  • Publication number: 20200233837
    Abstract: Indexing files to account for snapshots can include generating, based on a scan of the storage system, one or more file records. Each file record of the one or more file records can correspond to a file stored on the storage system at the time of the scan. The file records can be maintained based on one or more notifications received from the storage system. A snapshot list of the storage system can be maintained, the snapshot list having snapshot data corresponding to one or more snapshots stored on the storage system. A search result can be generated that satisfies a search parameter based at least on a) the one or more file records and/or b) the snapshot list.

  • Patent number: 9991895
    Abstract: A wireless radio-frequency transmission apparatus includes a phase frequency detector, a charge pump, a loop filter and a twin voltage-controlled oscillator. The twin voltage-controlled oscillator includes a first oscillator and a second oscillator. When the twin voltage-controlled oscillator is in a reception mode, the first and the second oscillators are coupled to each other to form a quadrature voltage-controlled oscillator, and the quadrature voltage-controlled oscillator, the phase frequency detector, the charge pump and the loop filter constitute a phase-locked loop to generate quadrature carriers. When the twin voltage-controlled oscillator is in a transmission mode, the first oscillator, the phase frequency detector, the charge pump and the loop filter constitute a phase-locked loop, and the second oscillator performs frequency modulation on transmitted data.
