Several high-stakes administrative tasks require supporting verdicts and decisions with auditable reasoning. While the application of LLMs in this regard has been studied, existing benchmarks are unsuitable because they either score only the final answer or evaluate citation quality separately from outcome correctness. We introduce HS-BENCH, a benchmark for customs classification, to study this problem. The task involves assigning tariff codes to products with reasoning grounded in legal authorities. HS-BENCH consists of 1,390 product descriptions paired with supporting legal authorities across diverse sources, including dictionary definitions, statutory notes, and prior rulings. We propose Strict Support Accuracy (SSA), a metric that credits a prediction only when both the outcome and the reasoning are well supported. Evaluating frontier models in closed-book and oracle-evidence regimes, we find that classification accuracy and SSA diverge sharply: models often reach the correct outcome through incorrect reasoning. We release the dataset, extraction pipeline, and evaluation code at https://github.com/adalat-ai-tech/hs-bench to support research on auditable LLM systems in administrative law.

This paper describes our system used in the SemEval-2023 Task 11 Learning With Disagreements (Le-Wi-Di). This is a subjective task since it deals with detecting hate speech, misogyny and offensive language. Thus, disagreement among annotators is expected. We experiment with different settings like loss functions specific for subjective tasks and include anonymized annotator-specific information to help us understand the level of disagreement. We perform an in-depth analysis of the performance discrepancy of these different modelling choices. Our system achieves a cross-entropy of 0.58, 4.01 and 3.70 on the test sets of HS-Brexit, ArMIS and MD-Agreement, respectively. Our code implementation is publicly available.

Identifying human values behind arguments isa complex task which requires understandingof premise, stance and conclusion together. Wepropose a method that uses a pre-trained lan-guage model, DeBERTa, to tokenize and con-catenate the text before feeding it into a fullyconnected neural network. We also show thatleveraging the hierarchy in values improves theperformance by .14 F1 score.

This paper presents our submission to the WebNLG Challenge 2023 for generating text in several low-resource languages from RDF-triples. Our submission focuses on using machine translation for generating texts in Irish, Maltese, Welsh and Russian. While a simple and straightfoward approach, recent works have shown that using monolingual models for inference for multilingual tasks with the help of machine translation (translate-test) can out-perform multilingual models and training multilingual models on machine-translated data (translate-train) through careful tuning of the MT component. Our results show that this approach demonstrates competitive performance for this task even with limited data.
