  In this article, I present the questions that I seek to answer in my PhD
research. I posit to analyze natural language text with the help of semantic
annotations and mine important events for navigating large text corpora.
Semantic annotations such as named entities, geographic locations, and temporal
expressions can help us mine events from the given corpora. These events thus
provide us with useful means to discover the locked knowledge in them. I pose
three problems that can help unlock this knowledge vault in semantically
annotated text corpora: i. identifying important events; ii. semantic search;
and iii. event analytics.
