Effective Modeling of Encoder-Decoder Architecture for Joint Entity and Relation Extraction

Understand

A relation tuple consists of two entities and the relation between them, and often such tuples are found in unstructured text.

• There may be multiple relation tuples present in a text and they may share one or both entities among them.
• Extracting such relation tuples from a sentence is a difficult task and sharing of entities or overlapping entities among the tuples makes it more challenging.
• Most prior work adopted a pipeline approach where entities were identified first followed by finding the relations among them, thus missing the interaction among the relation tuples in a sentence.
