Enhanced Distant Supervision with State-Change Information for Relation Extraction.
International Conference on Language Resources and Evaluation (LREC)(2022)
摘要
In this work, we introduce a method for enhancing distant supervision with state-change information for relation extraction. We provide a training dataset created via this process, along with manually-annotated development and test sets. We present an analysis of the curation process and data, and compare it to standard distant supervision. We demonstrate that the addition of state-change information reduces noise when used for static relation extraction, and can also be used to train a relation-extraction system that detects a change of state in relations.
