Abstract

The invention relates to a specific domain-oriented network user group division method and device, and the method comprises the steps: extracting semantic clue information corresponding to one or moredomains from collected network text data; determining an account sequence corresponding to each account in the account set according to the target semantic clue information of the target domain corresponding to the account set and the association relationship between the accounts in the account set, the account sequence comprising a plurality of accounts taking each account as a starting account;generating a second feature vector corresponding to each account according to the first feature vector of the account in the account sequence; and dividing accounts included in the account set into aplurality of network user groups according to the second feature vector. According to the method and the apparatus, the technical problem of relatively low accuracy when the network user groups are divided is solved.

Description

technical field [0001] The present application relates to the field of computers, in particular to a method and device for dividing network user groups for specific fields. Background technique [0002] With the development of the Internet, the discovery of network user groups for specific fields aims to discover potentially relevant network user groups for specific fields from multiple sources of massive network texts and associated network data, which plays an important role in the fields of business intelligence and network information supervision. Value. Existing methods mainly include three categories: methods based on deep learning, methods based on matrix decomposition, and methods based on probability models. However, the groups discovered by existing methods are not highly targeted and have low accuracy. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0004] In order to solve the above technical problems...
