Learning to Borrow– Relation Representation for Without-Mention Entity-Pairs for Knowledge Graph Completion

1 code implementation NAACL 2022 Huda Hakami, Mona Hakami, Angrosh Mandya, Danushka Bollegala

In this paper, we propose and evaluate several methods to address this problem, where we borrow LDPs from the entity pairs that co-occur in sentences in the corpus (i. e. with mentions entity pairs) to represent entity pairs that do not co-occur in any sentence in the corpus (i. e. without mention entity pairs).

Combining Long Short Term Memory and Convolutional Neural Network for Cross-Sentence n-ary Relation Extraction

no code implementations AKBC 2019 Angrosh Mandya, Danushka Bollegala, Frans Coenen, Katie Atkinson

We propose in this paper a combined model of Long Short Term Memory and Convolutional Neural Networks (LSTM-CNN) that exploits word embeddings and positional embeddings for cross-sentence n-ary relation extraction.
