Edge gateway modeling method based on TF-IDF algorithm

An edge gateway modeling method based on a TF-IDF algorithm is characterized by comprising the following steps: collecting edge gateway access side data according to actual field conditions, and storing the data into a database; reading transfer-out model library information, and calculating word frequency data TF of each data of the transfer-out model according to a word frequency algorithm in a TF-IDF algorithm; reading access side database information, and calculating word frequency data TF corresponding to description information of each data of the access device; respectively calculating inverse document frequencies (IDF) of the accessed and transferred entries, and generating TF-IDF data of each entry; according to the TF-IDF data of each entry, generating entry-based vector values of access data and a transfer-out model; and generating a forwarding side database through the established mapping relation. According to the method, the characteristic of text similarity of the TF-IDF algorithm is utilized,
