Pronouns: he/him

Hi! I am Siddharth (Sid). I am a fourth-year Computer Science Ph.D. student at the University of Rochester advised by Aaron White.

My research focus is in Natural Language Understanding and Information Extraction. I work on building computational models of semantics in natural language text. In my previous work, I have worked on building models for extracting semantic information related to events – event triggers, event chronology, event duration etc. I also collaborate with Ben Van Durme and his group at Johns Hopkins University on projects related to Information Extraction.

My papers are listed on the publications page. Full list of publications can be found at Semantic Scholar/Google Scholar

Fine-Grained Temporal Relation Extraction

We present a novel semantic framework for modeling temporal relations and event durations that maps pairs of events to real-valued scales. We use this framework to construct the largest temporal relations dataset to date, covering the entirety of the Universal Dependencies English Web Treebank. We use this dataset to train models for jointly predicting fine-grained temporal relations and event durations. We report strong results on our data and show the efficacy of a transfer-learning approach for predicting categorical relations.

Temporal Reasoning in Natural Language Inference

Vashishtha, Siddharth, Poliak, Adam, Lal, Yash Kumar, Van Durme, Benjamin, and White, Aaron Steven

In Findings of the Association for Computational Linguistics: EMNLP 2020

Abs PDF Code

We introduce five new natural language inference (NLI) datasets focused on temporal reasoning. We recast four existing datasets annotated for event duration{---}how long an event lasts{---}and event ordering{---}how events are temporally arranged{---}into more than one million NLI examples. We use these datasets to investigate how well neural models trained on a popular NLI corpus capture these forms of temporal reasoning.
