1. Structured Minimally Supervised Learning for Neural Relation Extraction Fan Bai and Alan Ritter NAACL 2019 paper code

   PGM | DSRE

   This paper adds a PGM inference into training stage.

2. Combining Distant and Direct Supervision for Neural Relation Extraction Iz Beltagy, Kyle Lo and Waleed Ammar NAACL 2019 paper code

   Combining Direct Supervision | DSRE

   This paper combines direct supervision and distant supervision. It innovatively uses direct supervision for training sigmoid attention in a multi-task way. Further, when applying to the CNN backbone with different filter sizes, adding entity embedding as additional inputs is a useful trick, which performs comparable to RESIDE and better than PCNN-ATT. After combining the supervised sigmoid attention, this paper become a new sota.

1. Graph Neural Networks with Generated Parameters for Relation Hao Zhu and Yankai Lin and Zhiyuan Liu, Jie Fu, Tat-seng Chua, Maosong Sun ACL 2019 paper

   GNN | new task | new perspective

   This paper considers multi-hop relation extraction, which constructs a fully-connected graph for all entities in a sentence. Experiments show that modeling entity-relation as a graph signifcantly improves the performance.

   | new dataset | new perspective| joint extraction of relations and entities

   In this paper, we propose a new paradigm for the task of entity-relation extraction. We cast the task as a multi-turn question answering problem, i.e., the extraction of entities and relations is transformed to the task of identifying answer spans fromthe context. Thismulti-turn QA formalization comes with several key advantages: firstly, the question query encodes important information for the entity/relation class we want to identify; secondly, QA provides a natural way of jointly modeling entity and relation; and thirdly, it allows us to exploit the well developed machine reading comprehension (MRC) models. Additionally, we construct a newly developed dataset RESUME in Chinese, which requires multi-step reasoning to construct entity dependencies, as opposed to the single-step dependency extraction in the triplet exaction in previous datasets.
