CAMB at CWI Shared Task 2018: Complex Word Identification with Ensemble-Based Voting

Abstract

This paper presents the winning systems we submitted to the Complex Word Identification Shared Task 2018. We describe our best performing systems' implementations and discuss our key findings from this research. Our best-performing systems achieve an F 1 score of 0.8736 on the NEWS, 0.8400 on the WIKINEWS and 0.8115 on the WIKIPEDIA test sets in the monolingual English binary classification track, and a mean absolute error of 0.0558 on the NEWS, 0.0674 on the WIKINEWS and 0.0739 on the WIKIPEDIA test sets in the probabilistic track.
