Knowledge based AI is a fundamental paradigm that has made continued progress since early expert systems in the 1970s. While inference techniques may be developed to perform a certain task in theory, acquiring the knowledge to perform it well in practice is another matter. For limited tasks, knowledge could be added manually or acquired using existing knowledge extraction techniques like pattern matching. However, as the scope of a task becomes more general the complexity and amount of knowledge becomes too great to rely on current approaches. This knowledge acquisition bottleneck greatly limits any inference technique and is a common obstacle in further developing very general knowledge based AI like common sense reasoning and \lu{}. In this thesis we will examine the knowledge bottle neck in \lu{} and how it relates to typical reasoning techniques in many \lu{} tasks. We examine the current state of knowledge available for those tasks as well as the types and scale of knowledge that is lacking. We then discuss techniques for acquiring symbolic knowledge about general concepts from dictionary sources using semantic parsing. We propose ways of augmenting the acquired knowledge with subtext that tends to be ignored by current methods which interpret definitions literally. This allows us to abstract concepts into frames and discover semantic relationships between concepts. We show that our process of adding subtext acquires more semantic relationships of similar accuracy compared to methods without added subtext.
