Social Network Analysis (SNA) is an appealing research topic, within the domain of Artificial Intelligence (AI), owing to its widespread application in the real world. In this dissertation, we have proposed effective Machine Learning (ML) and Deep Learning (DL) approaches toward resolving these open problems in SNA, viz: Breakup Prediction, Link Prediction, Node Classification, Event-based Analysis, and Trend/Pattern Analysis. Existing literature have focused on studying the apparent and latent interactions within social graphs as an n-ary operation, which yields binary outputs comprising positives (friends, likes, etc.) and negatives (foes, dislikes, etc.). Thus, as part of the research contributions in this dissertation, we have proposed an automatic technique toward flagging ties for breakups (negative-tie state) based on an n-ary operation which renders ternary outputs composed of positives, negatives, and intersections. Furthermore, SNA can be employed toward resolving several real-world problems; and ML as well as DL have proven to be very effective methodologies for accomplishing AI-related goals. 
Keywords: Social Network analysis (SNA), Artificial Intelligence (AI), Machine Learning (ML), Deep Learning (DL), breakup prediction, link prediction, node classification, event-based analysis, trend/pattern analysis
