Message Passing for Hyper-Relational Knowledge Graphs

1 code implementation EMNLP 2020 Mikhail Galkin, Priyansh Trivedi, Gaurav Maheshwari, Ricardo Usbeck, Jens Lehmann

We also demonstrate that existing benchmarks for evaluating link prediction (LP) performance on hyper-relational KGs suffer from fundamental flaws and thus develop a new Wikidata-based dataset - WD50K.

Learning to Rank Query Graphs for Complex Question Answering over Knowledge Graphs

1 code implementation2 Nov 2018 Gaurav Maheshwari, Priyansh Trivedi, Denis Lukovnikov, Nilesh Chakraborty, Asja Fischer, Jens Lehmann

In this paper, we conduct an empirical investigation of neural query graph ranking approaches for the task of complex question answering over knowledge graphs.

Fair NLP Models with Differentially Private Text Encoders

1 code implementation12 May 2022 Gaurav Maheshwari, Pascal Denis, Mikaela Keller, Aurélien Bellet

Encoded text representations often capture sensitive attributes about individuals (e. g., race or gender), which raise privacy concerns and can make downstream models unfair to certain groups.

Formal Ontology Learning from English IS-A Sentences

no code implementations11 Feb 2018 Sourish Dasgupta, Ankur Padia, Gaurav Maheshwari, Priyansh Trivedi, Jens Lehmann

Ontology learning (OL) is the process of automatically generating an ontological knowledge base from a plain text document.

SimDoc: Topic Sequence Alignment based Document Similarity Framework

no code implementations15 Nov 2016 Gaurav Maheshwari, Priyansh Trivedi, Harshita Sahijwani, Kunal Jha, Sourish Dasgupta, Jens Lehmann

Document similarity is the problem of estimating the degree to which a given pair of documents has similar semantic content.

BitSim: An Algebraic Similarity Measure for Description Logics Concepts

no code implementations19 Mar 2015 Sourish Dasgupta, Gaurav Maheshwari, Priyansh Trivedi

In this paper, we propose an algebraic similarity measure {\sigma}BS (BS stands for BitSim) for assigning semantic similarity score to concept definitions in ALCH+ an expressive fragment of Description Logics (DL).

An End-to-End Approach for Full Bridging Resolution

no code implementations ACL (CODI, CRAC) 2021 Joseph Renner, Priyansh Trivedi, Gaurav Maheshwari, Rémi Gilleron, Pascal Denis

We demonstrate the performance of an end-to-end transformer-based higher-order coreference model finetuned for the task of full bridging.

FairGrad: Fairness Aware Gradient Descent

no code implementations22 Jun 2022 Gaurav Maheshwari, Michaël Perrot

We address the problem of group fairness in classification, where the objective is to learn models that do not unjustly discriminate against subgroups of the population.

Fair Without Leveling Down: A New Intersectional Fairness Definition

no code implementations21 May 2023 Gaurav Maheshwari, Aurélien Bellet, Pascal Denis, Mikaela Keller

In this work, we consider the problem of intersectional group fairness in the classification setting, where the objective is to learn discrimination-free models in the presence of several intersecting sensitive groups.
