Systems and methods for assessing similarity of documents are provided. Embodiments of the systems and methods include extracting a reference document text from a reference document, extracting an archived document text from an archived document, and quantifying the reference document and the archived document. The systems and methods may also include determining a document similarity value of the quantified reference document and the archived document. Determining the document similarity value includes calculating a set of vector similarity values for a set of combinations of a reference document text vector and an archived document text vector, and calculating the document similarity value, including a sum of the plurality of vector similarity values.

Method and system for assessing similarity of documents

A method for document similarity analysis. The method includes generating a reference document content identifier for a reference document, including identifying frequently occurring terms in reference document content, encoding each frequently occurring term in a term identifier and combining the term identifiers to form the reference document content identifier associated with the reference document. The method also includes obtaining at least one document similarity value by comparing the reference document content identifier to a set of archived document content identifiers stored in a document repository.

An object of the present disclosure is to provide a beamforming method for a massive MIMO system. Specifically, S routes of data streams to be transmitted via the antenna array are subjected to horizontal direction baseband beamforming processing, to obtain T routes of data streams; the T-routes of data streams are subjected to vertical direction digital beamforming processing to map the T routes of data streams onto a corresponding channel according to a predetermined rule; a data stream on each channel is subjected to analog beamforming processing to map the data stream on each channel onto a corresponding array element of the antenna array for transmission. Compared with the prior art, the present disclosure implements the following advantages: by combining the advantages of RF beamforming with the BB beamforming with limited antennas at the FH, a good flexibility regarding BB algorithm selection and RF beam design is provided, which balances the complexity and performance between BB and RF and implements a massive MIMO in sub-6 GHz.

Embodiments of the present disclosure relate to a method, a device, and a computer-readable storage medium for allocating system resources among a plurality of network slices in a communication network. In the communication network, a network device determines utility values of two network slices. A network slice corresponds to a set of network functions of a set of services served thereby. A utility value of the network slice indicates the level of demand for system resources by the set of services associated with the network slice. The network device determines a difference between the utility values of the two network slices. If the difference exceeds a threshold utility value, the network device re-allocates system resources among the plurality of network slices in the communication network. According to the embodiments, the communication network updates the system resources allocated for the plurality of network slices only when the difference between the utility values of the two network slices exceeds a certain threshold. Hence, the complexity of updating system resource allocation among the plurality of network slices may be reduced by the method according to the embodiments of the present disclosure.
