Relation Extraction with Self-determined Graph Convolutional Network

no code implementations2 Aug 2020 Sunil Kumar Sahu, Derek Thomas, Billy Chiu, Neha Sengupta, Mohammady Mahdy

The state-of-the-art methods use linguistic tools to build a graph for the text in which the entities appear and then a Graph Convolutional Network (GCN) is employed to encode the pre-built graphs.

Inter-sentence Relation Extraction with Document-level Graph Convolutional Neural Network

no code implementations ACL 2019 Sunil Kumar Sahu, Fenia Christopoulou, Makoto Miwa, Sophia Ananiadou

Inter-sentence relation extraction deals with a number of complex semantic relationships in documents, which require local, non-local, syntactic and semantic dependencies.

Siamese Neural Networks with Random Forest for detecting duplicate question pairs

no code implementations22 Jan 2018 Ameya Godbole, Aman Dalmia, Sunil Kumar Sahu

We got the best result by using the Siamese adaptation of a Bidirectional GRU with a Random Forest classifier, which landed us among the top 24% in the competition Quora Question Pairs hosted on Kaggle.

Investigating how well contextual features are captured by bi-directional recurrent neural network models

no code implementations WS 2017 Kushal Chawla, Sunil Kumar Sahu, Ashish Anand

Our experiments focus on important contextual words as features, which can easily be extended to analyze various other feature types.

What matters in a transferable neural network model for relation classification in the biomedical domain?

no code implementations11 Aug 2017 Sunil Kumar Sahu, Ashish Anand

We systematically investigate effectiveness of the proposed frameworks in transferring the knowledge under multiple aspects related to source and target tasks, such as, similarity or relatedness between source and target tasks, and size of training data for source task.

Unified Neural Architecture for Drug, Disease and Clinical Entity Recognition

no code implementations11 Aug 2017 Sunil Kumar Sahu, Ashish Anand

Three important characteristics of the framework are as follows - (1) model learns contextual as well as morphological features using two different BLSTM in hierarchy, (2) model uses first order linear conditional random field (CRF) in its output layer in cascade of BLSTM to infer label or tag sequence, (3) model does not use any domain specific features or dictionary, i. e., in another words, same set of features are used in the three NER tasks, namely, disease name recognition (Disease NER), drug name recognition (Drug NER) and clinical entity recognition (Clinical NER).

Drug-Drug Interaction Extraction from Biomedical Text Using Long Short Term Memory Network

1 code implementation28 Jan 2017 Sunil Kumar Sahu, Ashish Anand

The two models, {\it AB-LSTM} and {\it Joint AB-LSTM} also use attentive pooling in the output of Bi-LSTM layer to assign weights to features.

Recurrent neural network models for disease name recognition using domain invariant features

no code implementations ACL 2016 Sunil Kumar Sahu, Ashish Anand

In particular, we propose various end-to-end recurrent neural network (RNN) models for the tasks of disease name recognition and their classification into four pre-defined categories.
