Discovering Knowledge Graph Schema from Short Natural Language Text via Dialog

no code implementations SIGDIAL (ACL) 2020 Subhasis Ghosh, Arpita Kundu, Aniket Pramanick, Indrajit Bhattacharya

For such mini-dialogs with response uncertainty, we propose a dialog strategy that looks to elicit the schema over as short a dialog as possible.

Do the Benefits of Joint Models for Relation Extraction Extend to Document-level Tasks?

no code implementations1 Oct 2023 Pratik Saini, Tapas Nayak, Indrajit Bhattacharya

Joint models, which capture interactions across triples, are the more recent development, and have been shown to outperform pipeline models for sentence-level extraction tasks.

Do I have the Knowledge to Answer? Investigating Answerability of Knowledge Base Questions

no code implementations20 Dec 2022 Mayur Patidar, Prayushi Faldu, Avinash Singh, Lovekesh Vig, Indrajit Bhattacharya, Mausam

When answering natural language questions over knowledge bases, missing facts, incomplete schema and limited scope naturally lead to many questions being unanswerable.

Generating An Optimal Interview Question Plan Using A Knowledge Graph And Integer Linear Programming

no code implementations NAACL 2021 Soham Datta, Prabir Mallick, Sangameshwar Patil, Indrajit Bhattacharya, Girish Palshikar

Given the diversity of the candidates and complexity of job requirements, and since interviewing is an inherently subjective process, it is an important task to ensure consistent, uniform, efficient and objective interviews that result in high quality recruitment.

Joint Learning of Representations for Web-tables, Entities and Types using Graph Convolutional Network

no code implementations EACL 2021 Aniket Pramanick, Indrajit Bhattacharya

Existing approaches for table annotation with entities and types either capture the structure of table using graphical models, or learn embeddings of table entries without accounting for the complete syntactic structure.

Enabling human-like task identification from natural conversation

no code implementations23 Aug 2020 Pradip Pramanick, Chayan Sarkar, Balamuralidhar P, Ajay Kattepur, Indrajit Bhattacharya, Arpan Pal

In this work, we provide a non-trivial method to combine an NLP engine and a planner such that a robot can successfully identify tasks and all the relevant parameters and generate an accurate plan for the task.

Discovering Topical Interactions in Text-based Cascades using Hidden Markov Hawkes Processes

no code implementations12 Sep 2018 Srikanta Bedathur, Indrajit Bhattacharya, Jayesh Choudhari, Anirban Dasgupta

We show using experiments on real and semi-synthetic data that HMHP is able to generalize better and recover the network strengths, topics and diffusion paths more accurately than state-of-the-art baselines.

Nested Hierarchical Dirichlet Processes for Multi-Level Non-Parametric Admixture Modeling

no code implementations26 Aug 2015 Lavanya Sita Tekumalla, Priyanka Agrawal, Indrajit Bhattacharya

The Hierarchical Dirichlet Process (HDP), is an extension of DP for grouped data, often used for non-parametric topic modeling, where each group is a mixture over shared mixture densities.

Test Set Selection using Active Information Acquisition for Predictive Models

no code implementations3 Dec 2013 Sneha Chaudhari, Pankaj Dayama, Vinayaka Pandit, Indrajit Bhattacharya

Arising in the context of two rather disparate applications- banking and medical diagnosis, we pose the active information acquisition problem as a constrained optimization problem.
