Knowledge Graphs (KGs) are the backbone of reliable industrial data strategies, yet verbalizing them with Large Language Models (LLMs) often leads to unacceptable risks for high-stakes applications, such as hallucinations or omitted relations. To enforce strict semantic fidelity in KG-to-text generation, we introduce a self-supervised round-trip pipeline. The system verbalizes KG triples into text and immediately attempts to reconstruct the original graph from that text; only verbalizations that enable perfect graph recovery are retained. This creates a closed feedback loop that guarantees the generated text is semantically equivalent to the source data. Experiments confirm that our automated round-trip consistency score correlates strongly with expert judgment, effectively acting as a scalable proxy for human review. Furthermore, we show that standard LLMs can bootstrap their own KG-extraction and generation capabilities by fine-tuning on this trusted synthetic data. Our approach yields significant improvements in triple-extraction accuracy and verbalization faithfulness without relying on costly manual annotation or massive teacher models, offering a practical path to deploying trustworthy, KG-grounded AI systems.

2022 Annual Conference of the North American Chapter of the Association for Computational Linguistics

technical paper

It is my great pleasure and honor to welcome you to the 64th Annual Meeting of the Association for Computational Linguistics (ACL 2026), held in San Diego, California, USA, July 2–7, 2026. ACL 2026 continues our fields tradition of excellence in scholarship, innovation, and inclusivity, and I am deeply grateful to the many volunteers who have worked tirelessly to bring this event to life.

It is exciting to see the many developments in the field reflected at our conference, such as the advancement of large language models (born out of our community) into many application directions. This is not without challenges, partly due to unsolved problems, and partly due to misuse of the technology. All this is reflected well at ACL 2026. The conference also reflects that the field is not only about advancing technology, but also the science of fundamentally understanding language and how it is use by many different speaker communities.

We present a deployed system that automates end-to-end customer support workflows inside an enterprise Business Process Management (BPM) platform. The approach is scalable in production and reaches selective automation within two weeks for a new process, leveraging supervision already generated at scale: structured per-case UI interaction traces and low-overhead copilot feedback, where operators either accept a suggestion or provide a correction. A staged deployment pipeline trains a next UI action policy, learns a critic from copilot feedback to calibrate abstention, and executes only high-confidence steps in the background while deferring uncertain decisions to operators and resuming from the updated UI state. This setup lets one operator supervise multiple concurrent sessions and be interrupted only when the system is uncertain. The system operates on a schema-driven view of the BPM interface and includes monitoring and safe fallbacks for production. In production, it automated 45% of sessions and reduced average handling time by 39% without degrading support quality level.

Learning Selective LLM Autonomy from Copilot Feedback in Enterprise Customer Support Workflows

Mechanistic interpretability aims to reverse-engineer large language models (LLMs) into human-understandable computational circuits. However, the complexity of pretrained models often obscures the minimal mechanisms required for specific reasoning tasks. In this work, we train small, attention-only transformers from scratch on a symbolic version of the Indirect Object Identification (IOI) task, a benchmark for studying coreference-like reasoning in transformers. Surprisingly, a single-layer model with only two attention heads achieves perfect IOI accuracy, despite lacking MLPs and normalization layers. Through residual stream decomposition, spectral analysis, and embedding interventions, we find that the two heads specialize into additive and contrastive subcircuits that jointly implement IOI resolution. Furthermore, we show that a two-layer, one-head model achieves performance comparable to that of a multi-head model by composing information across layers primarily through query-key interactions. These results demonstrate that task-specific training induces highly interpretable, minimal circuits, offering a controlled testbed for probing the computational foundations of transformer reasoning.

Emergence of Minimal Circuits for Indirect Object Identification in Attention-Only Transformers

Logical fallacy detection models frequently over-flag valid reasoning due to reliance on surface-level spurious correlations, a brittleness that persists even in state-of-the-art benchmarks like CoCoLoFa despite strong in-distribution performance. This study introduces a targeted debiasing strategy using 703 LLM-generated counterfactually augmented pairs ---minimally differentiated valid and fallacious arguments matched on topic, structure, and wording---to isolate logical distinctions beyond superficial cues. Fine-tuning DeBERTa-v3-large on CoCoLoFa augmented with these pairs yields only marginal in-distribution improvement (+0.4\% F1 on the test set) but delivers substantial out-of-distribution robustness: a 58\% relative reduction in false positive rate (64\% 26.7\%) on a 300-sample balanced manual evaluation set curated from Reddit and other real-world sources. Zero-shot evaluation of recent LLMs (Llama-3.1-8B and Llama-3.3-70B) shows high performance under carefully optimized prompts (F1 90--94\%), but severe degradation under simple human-like prompts (F1 63--72\%, FPR rising to 54--74\%) and partial recovery with few-shot examples (F1 83--90\%, FPR 21--34\%). In contrast, the proposed lightweight and prompt-invariant approach achieves competitive robustness (F1 85.9\%, FPR 26.7\%) across all prompting regimes without any dependence on prompt engineering. This makes the method particularly stable for environments with unpredictable user input. The 703-pair counterfactual dataset, the fine-tuned model, and an interactive Hugging Face demo are publicly released to facilitate further research in misinformation detection and argumentation analysis.

Debiasing Logical Fallacy Detection for Real-World Robustness via Counterfactually Augmented Data

User-level ADHD-related text classification from social media is methodologically challenging because predictions must aggregate many short posts, performance can be inflated by direct diagnostic leakage, and screening-adjacent settings require calibrated probabilities rather than discrimination alone. We introduce a leakage-aware evaluation framework organized around two controlled axes: evidence budget, i.e., the number of tweets available per user, and leakage control. Within this setup, we compare document-level transformers, strong non-graph embedding-pooling baselines, and heterogeneous graph models combining semantic tweet embeddings, psycholinguistic features, and temporal structure. The main result is regime-dependent: graph aggregation is most useful when user evidence is scarce, whereas simple embedding pooling becomes highly competitive and often slightly stronger as more evidence becomes available. Overall, the main contribution is a controlled benchmarking framework and a clearer account of when graph-based aggregation is actually beneficial.

Leakage-Aware User-Level ADHD Signal Classification from Social Media: When Graph Aggregation Helps, and When It Does Not

Speaker diarization systems produce segmentation errors, such as false splits and boundary misplacements, that degrade transcript readability and downstream applications. We present CBAL (Context-Based Agentic Learning), a post-processing framework that refines segmentation boundaries in diarized scripts through targeted error correction. CBAL detects potential segmentation errors using acoustic and temporal heuristics and employs a lightweight LLM agent to reason about merge decisions, validating corrections through uncertainty-aware filtering with signal-based constraints. CBAL achieves 93.4\% accuracy across 359 applied merges and reduces segment count by 6.1\%. We demonstrate that our framework identifies and corrects high-confidence errors while maintaining 0\% degradation in terms of concatenated minimum-permutation Word Error Rate (cpWER). An ablation study confirms that each component contributes non-redundantly, demonstrating the viability of interpretable refinement frameworks that use the strengths of acoustic models and language understanding without requiring end-to-end retraining.

CBAL: Context-Based Agentic Learning for Speaker Diarization Segmentation Refinement

We study cross-lingual transfer by fine-tuning seven large language models (4B--671B parameters) on Arabic and evaluating zero-shot reading comprehension on Semitic languages and non-Semitic controls. Across dense and Mixture-of-Experts architectures, we find no evidence of Semitic-specific transfer: models with weak baselines improve dramatically across all languages, while strong-baseline models show only marginal gains regardless of language family. A chain-of-thought ablation reinforces this finding---the same models that benefit most from fine-tuning benefit equally from inference-time reasoning, suggesting both mechanisms address task-format alignment rather than cross-lingual knowledge transfer.

Disentangling Linguistic Relatedness from Task Alignment in Cross-Lingual Transfer

Organizations must continuously monitor evolving regulations to maintain compliance. While current tools are limited to surface-level text comparison, existing models lack the fine-grained classification schemes to determine whether small changes impact legal obligations or merely update formatting. To address this gap, we introduce a novel benchmark for change detection in EU regulations. It comprises 4,772 manually annotated pairs of structurally distinct provisions, defined as Atomic Legal Units (ALUs), mapped to a six-class taxonomy. We formalize three core tasks: structural alignment, change classification, and a combined task requiring simultaneous alignment and classification. Evaluating baselines from lexical algorithms to Large Language Models (LLMs), we find LLMs excel at isolated change classification, whereas domain-specific dense encoders offer the most robust combined performance. By providing fine-grained labeled data, this benchmark enables the development of AI systems that can help organizations analyze regulatory shifts and support version-aware retrieval in the legal domain.

RegTrack: A Fine-Grained Benchmark for Multi-Class Legal Change Detection

Reliable automatic evaluation is essential for benchmarking Machine Translation (MT) systems. However, their reliability is often underexplored in morphologically complex, non-English-centric contexts. Current metrics frequently exhibit "semantic blindness" toward subtle morphological shifts in morphologically rich languages like Finnish. This study proposes a framework that utilizes a controlled perturbation suite to systematically isolate and quantify the metric sensitivity to morphosemantic errors in Swedish to Finnish translation. It combines authentic MT outputs with a tiered adversarial corpus, subjecting reference translations. It will quantify discriminative ability and ordinal monotonicity by leveraging a diverse evaluation suite.

We present **Copyright Detective**, the first interactive forensic system for detecting, analyzing, and visualizing potential copyright risks in LLM outputs. The system treats copyright infringement versus compliance as an **evidence discovery** process rather than a static classification task due to the complex nature of copyright law. It integrates multiple detection paradigms, including content recall testing, paraphrase-level similarity analysis, persuasive jailbreak probing, and unlearning verification, within a unified and extensible framework. Through interactive prompting, response collection, and iterative workflows, our system enables systematic auditing of verbatim memorization and paraphrase-level leakage, supporting responsible deployment and transparent evaluation of LLM copyright risks even with black-box access. In our experiments with GPT-4o-mini, we demonstrate that specific persuasive strategy "Pathos" shift the leakage distribution from about 0.1 (ROUGE-L) to 0.7. Our live system is hosted on [Streamlit](https://copyright-detective.streamlit.app), and the source code will be made publicly available at [GitHub](https://github.com/changhu73/Copyright-Detective) upon acceptance. In addition, a [demo video](https://youtu.be/10gmwV3q_gg) is also included as supplementary material.

We demonstrate Hindsight, a working memory system for AI agents that organizes long-term memory into four logical networks and exposes three core operations. The world, experience, observation, and opinion networks separate objective facts from subjective beliefs, giving developers clear visibility into what an agent knows versus what it believes. The retain, recall, and reflect operations handle memory ingestion, retrieval, and reasoning respectively. The retrieval layer combines vector search, keyword matching, graph traversal, and temporal filtering in a parallel pipeline backed by PostgreSQL with pgvector. Unlike existing memory systems such as MemGPT, Zep, and Mem0, Hindsight is the only system that jointly provides fact-belief separation, temporal entity graphs, evolving opinions with confidence scores, and configurable behavioral profiles. On the LongMemEval and LoCoMo benchmarks, Hindsight with a 20B open-source model achieves 83.6% and 83.2% accuracy, outperforming full-context GPT-4o and all prior memory systems; with Gemini-3 Pro, accuracy reaches 91.4% on LongMemEval. Our interactive demonstration lets users build memory graphs through multi-session conversations, inspect how memories are classified across networks, and observe how agent opinions form and change over time. The system is $\textbf{open-source under the MIT license}$ and available as a Python package (pip install hindsight-all) and Docker image, with $\textbf{1.9K GitHub stars}$ and 191 forks till date.A video demo is at https://youtu.be/4M2wS-yEmVA.
