An Architecture of Semantic Information Extraction Tool Text2ALM

Abstract

In this work we design a narrative understanding tool TEXT2ALM. This tool uses an action language ALM to perform inferences on complex interactions of events described in narratives. The methodology used to implement the TEXT2ALM system was originally outlined by Lierler, Inclezan, and Gelfond [11] via a manual process of converting a narrative to an ALM model. It relies on a conglomeration of resources and techniques from two distinct fields of artificial intelligence, namely, natural language processing and knowledge representation and reasoning. The effectiveness of system TEXT2ALM is measured by its ability to correctly answer questions from the bAbI tasks by Facebook Research in 2015. This tool matched or exceeded the performance of state-of-the-art machine learning methods in six of the seven tested tasks.
