The focus is implicit relations, where no connective such as "because" signals the link between two text spans. Earlier systems used cross-argument word pairs as discrete features, which produced very sparse feature spaces.… 2. **[Balancing Classification and Calibration Performance in Decision-Making LLMs via Calibration Aware Reinforcement Learning](https://md.research.elamur.ai/free/en/papers/yaldiz-2026-balancing-classification-calibration-performance-decision/)** *(2026)* LLMs used for decisions such as content moderation or clinical support need confidence scores that tell downstream systems when to fall back to a larger model or a human. ## All works 3 works of theirs in our library, the most cited first; 2 with a page here, the others link their original until we summarise them. 1. **[Instruction Tuning for Few-Shot Aspect-Based Sentiment Analysis ↗](https://aclanthology.org/2023.wassa-1.3/) Proceedings of the 13th Workshop on Computational Approaches to Subjectivity, Sentiment, & Social Media Analysis · no summary yet**Siddharth Varia et al.*2023 · 58 citations* 2. **[Discourse Relation Prediction: Revisiting Word Pairs with Convolutional Networks](https://md.research.elamur.ai/free/en/papers/varia-2019-discourse-relation-prediction-revisiting-word/) [Annual Meeting of the Special Interest Group on Discourse and Dialogue (SIGDIAL)](https://md.research.elamur.ai/free/en/venues/sigdial/)**Siddharth Varia, Christopher Hidey, Tuhin Chakrabarty*2019 · 39 citations* 3. **[Balancing Classification and Calibration Performance in Decision-Making LLMs via Calibration Aware Reinforcement Learning](https://md.research.elamur.ai/free/en/papers/yaldiz-2026-balancing-classification-calibration-performance-decision/) [Findings of the Association for Computational Linguistics](https://md.research.elamur.ai/free/en/venues/findings/)**Duygu Nur Yaldiz, Evangelia Spiliopoulou, Zheng Qi, et al.*2026* ## Co-authors here 6 co-authors with a page, the most papers together first. - [Christopher Hidey](https://md.research.elamur.ai/free/en/authors/christopher-hidey/) - [Evangelia Spiliopoulou](https://md.research.elamur.ai/free/en/authors/evangelia-spiliopoulou/) - [Nikolaos Pappas](https://md.research.elamur.ai/free/en/authors/nikolaos-pappas/) - [Srikanth Doss](https://md.research.elamur.ai/free/en/authors/srikanth-doss/) - [Tuhin Chakrabarty](https://md.research.elamur.ai/free/en/authors/tuhin-chakrabarty/) - [Zheng Qi](https://md.research.elamur.ai/free/en/authors/zheng-qi/) ## Venues Where their works here were published, the most works first, with the editions of those that have a page. - [Findings of the Association for Computational Linguistics](https://md.research.elamur.ai/free/en/venues/findings/): [Findings of the Association for Computational Linguistics 2026](https://md.research.elamur.ai/free/en/venues/findings/2026/) - [Annual Meeting of the Special Interest Group on Discourse and Dialogue (SIGDIAL)](https://md.research.elamur.ai/free/en/venues/sigdial/): [SIGDIAL 2019](https://md.research.elamur.ai/free/en/venues/sigdial/2019/) - Proceedings of the 13th Workshop on Computational Approaches to Subjectivity, Sentiment, & Social Media Analysis ## Cited by Papers of our library cite their works 35 times (of the 149,439 papers whose bibliographies we read); [8 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/siddharth-varia/cited-by/).
