Abstract: Provided are a system for recommending related data based on similarity, and a method thereof, the system including: a data collection device; an event extraction device; a data cleansing device; an event vector generation device; an artificial intelligence learning device; and a similar data recommendation device. The present disclosure is directed to providing a system for recommending related data based on similarity and a method thereof, wherein unstructured open data on a webpage is collected to automatically generate an event label for determining a similarity relation, and an artificial intelligence (AI)-based model is trained to group and recommend semantically similar related data, thereby effectively helping users including data scientists who want to see meaningful results through open data.

Abstract: Transaction management methods for enhancing data stability of a NoSQL DB based on a distributed file system are presented. The methods include, for instance: initializing a data storage transaction in which the distributed file system stores a logical file in the NoSQL DB, writing, by the distributed file system, the logical file into an inter-file IF, and moving, by the distributed file system, the inter-file to a physical file of the NoSQL DB when commit on a transaction occurs.
