In a computer-implemented method for generating a knowledge graph of interaction information, a data item including an interaction between at least two entities is received. A knowledge tuple for the data item is generated, the knowledge tuple including entities of the data item and a topic of the interaction of the data item. At least one thread to which the data item corresponds is identified, wherein a thread includes connected data items. An interaction tuple for the data item is generated, the interaction tuple including the entities of the data item, the thread corresponding to the data item, and a type of interaction of the data item. The knowledge graph is populated with the knowledge tuple and the interaction tuple, the knowledge graph including nodes associated with the entities, the topics, and the interactions, wherein the nodes associated with interactions include the type of interaction and thread of the data item.
