Abstract: Provided is a system and method for economic virtuous cycle simulation based on an artificial intelligence (AI) twin. The system for economic virtuous cycle simulation based on an AI twin includes an AI twin initial training unit configured to perform initial training on an AI twin model and learn initial parameters using an economic model, an AI twin optimization training unit configured to perform optimization tuning on the initial parameters of the AI twin model using past data collected in an initially trained model, an AI twin generating unit configured to generate an AI twin based on a learning model, and an AI twin operation unit configured to acquire an index for economic prediction to update the AI twin and perform an AI twin-based simulation.

Abstract: Provided is an engine container configured by a workflow engine framework for a cross-domain extension, including a plurality of operators configured to interwork with a plurality of representational state transfer (REST) application programming interfaces (APIs), respectively, a runner configured to sequentially call the plurality of operators according to a request from a client, and a controller configured to control an operation of the plurality of operators and the runner, wherein each operator operates in a pipeline manner to call a corresponding REST API using uniform resource locator (URL) information transferred from the runner and to transfer a processing result obtained by processing data provided through the corresponding called REST API to a next operator.

Abstract: A workflow engine framework for creating a single-domain adaptive and a cross-domain adaptive workflow performing platform is disclosed. The workflow engine framework includes: a resource management unit configured to manage resources including engine components and workflow property specification components; a system configuration unit configured to create an engine by assembling the property specification components; and a system control unit configured to drive and execute one or more engines. Further the workflow engine framework is allocated to each of two or more different signal domains and forms a cross-domain adaptive workflow engine framework.

Abstract: A method for indexing a suffix tree in a social network includes: scanning an input string and dividing the string into partitions each having a common prefix; performing no-merge suffix tree indexing on the divided partitions; storing information on the partitions on which no-merge suffix tree indexing is performed; storing suffix nodes of the no-merge suffix tree; and establishing a prefix tree. The performing no-merge suffix tree indexing includes: generating a set of suffixes having the common prefix in the input string; generating a suffix set from the set of suffixes and storing the suffix set; and building the suffix set as a sub-tree.
