CMUML Micro-Reader System for KBP 2016 Cold Start Slot Filling, Event Nugget Detection, and Event Argument Linking

In this paper, we present an overview of the CMUML’s Micro-Reader system for three TAC KBP tasks: Cold Start Slot Filling (SF); Event Nugget Detection and Coreference (EN); and Event Argument Extraction and Linking (EAL). The Micro-Reader system is a result of the CMU NELL team’s research efforts on single-document understanding using background knowledge. It is a generalpurpose machine reading system that takes as input a text document and outputs spanlevel semantic annotations for document understanding. There are several reading components in the Micro-Reader, each having a different reading capability. For the SF task, we aggregate the outputs of different reading components to propose KB assertions that can be used to answer the SF queries. For the EN and EAL tasks, we mainly utilize the event reading component of the MicroReader, which performs joint inference of entities and events within a document context.
