| 2026 | TencentLLMEval: A Hierarchical Evaluation of Real-World Capabilities for Human-Aligned LLMsabstractLarge language models (LLMs) have shown impressive capabilities across various natural language tasks. However, evaluating their alignment with human preferences remains a challenge. To this end, we propose a comprehensive human evaluation framework to assess LLMs’ proficiency in following instructions on diverse real-world tasks. We construct a hierarchical task tree encompassing seven major areas covering over 200 categories and over 800 tasks, which covers diverse capabilities such as question answering, reasoning, multi-turn dialogue, and text generation, to evaluate LLMs in a comprehensive and in-depth manner. We also design detailed evaluation standards and processes to facilitate consistent, unbiased judgments from human evaluators. A test set of over 3,000 instances is released, spanning different difficulty levels and knowledge domains. Our work provides a standardized methodology to evaluate human alignment in LLMs for both English and Chinese. We also analyze the feasibility of automating parts of evaluation with a strong LLM (GPT-4). Our framework supports a thorough assessment of LLMs as they are integrated into real-world applications. We have made publicly available the task tree, TencentLLMEval dataset, and evaluation methodology which have been demonstrated as effective in assessing the performance of Tencent Hunyuan LLMs. By doing so, we aim to facilitate the benchmarking of advances in the development of safe and human-aligned LLMs. Shuyi Xie, Wenlin Yao, Yong Dai 0001, Zishan Xu, Fan Lin, Donglin Zhou, Lifeng Jin, Xinhua Feng, Pengzhi Wei, Zhichao Hu, Dong Yu 0001, Zhengyou Zhang |

| 2021 | A New Approach Customizable Distributed Network Service Discovery SystemabstractComputer systems and applications on the internet provide services to outsiders and, at the same time, the vulnerabilities may be exploited by attackers and leak some sensitive private information. To collect and monitor the service information provided by the network environment such as IoT (Internet of Things), vehicular networks, cloud computing, and cloud storage, it is particularly important that a system can provide faster service discovery for discovering and identifying specific network services. The current service discovery systems mainly use port scanning technology, including Nmap, Zmap, and Masscan. However, these technologies hard code the service features and only support common services so that cannot cope with real‐time updates and changing network services. To solve the above problems, this paper proposed a customizable distributed network service discovery system based on stateless scanning technology of Masscan and proposed a customizable interactive pattern set syntax. The system used random destination address technologies to scan for Ipv4 address allocation and used a distributed deployment scheme. Experimental results show that the system has high scanning speed and has high adaptability to new services and special services. Xiangzhan Yu, Zhichao Hu, Yi Xin 0002 |

| 2018 | Modeling Linguistic and Personality Adaptation for Natural Language GenerationabstractPrevious work has shown that conversants adapt to many aspects of their partners' language.Other work has shown that while every person is unique, they often share general patterns of behavior.Theories of personality aim to explain these shared patterns, and studies have shown that many linguistic cues are correlated with personality traits.We propose an adaptation measure for adaptive natural language generation for dialogs that integrates the predictions of both personality theories and adaptation theories, that can be applied as a dialog unfolds, on a turn by turn basis.We show that our measure meets criteria for validity, and that adaptation varies according to corpora and task, speaker, and the set of features used to model it.We also produce fine-grained models according to the dialog segmentation or the speaker, and demonstrate the decaying trend of adaptation.

| 2017 | Inferring Narrative Causality between Event Pairs in FilmsabstractTo understand narrative, humans draw inferences about the underlying relations between narrative events.Cognitive theories of narrative understanding define these inferences as four different types of causality, that include pairs of events A, B where A physically causes B (X drop, X break), to pairs of events where A causes emotional state B (Y saw X, Y felt fear).Previous work on learning narrative relations from text has either focused on "strict" physical causality, or has been vague about what relation is being learned.This paper learns pairs of causal events from a corpus of film scene descriptions which are action rich and tend to be told in chronological order.We show that event pairs induced using our methods are of high quality and are judged to have a stronger causal relation than event pairs from Rel-grams.

| 2013 | Unsupervised Induction of Contingent Event Pairs from Film ScenesabstractHuman engagement in narrative is partially driven by reasoning about discourse relations between narrative events, and the expectations about what is likely to happen next that results from such reasoning.Researchers in NLP have tackled modeling such expectations from a range of perspectives, including treating it as the inference of the CONTINGENT discourse relation, or as a type of common-sense causal reasoning.Our approach is to model likelihood between events by drawing on several of these lines of previous work.We implement and evaluate different unsupervised methods for learning event pairs that are likely to be CONTINGENT on one another.We refine event pairs that we learn from a corpus of film scene descriptions utilizing web search counts, and evaluate our results by collecting human judgments of contingency.Our results indicate that the use of web search counts increases the average accuracy of our best method to 85.64% over a baseline of 50%, as compared to an average accuracy of 75.15% without web search.
