InFoBench: Evaluating Instruction Following Ability in Large Language Models

ACL 2024findings

This paper introduces the Decomposed Requirements Following Ratio (DRFR), a new metric for evaluating Large Language Models’ (LLMs) ability to follow instructions. Addressing a gap in current methodologies, DRFR breaks down complex instructions into simpler criteria, facilitating a detailed analysis…

MMC: Advancing Multimodal Chart Understanding with Large-scale Instruction Tuning

NAACL 2024long

With the rapid development of large language models (LLMs) and their integration into large multimodal models (LMMs), there has beenimpressive progress in zero-shot completion of user-oriented vision-language tasks. However, a gap remains in the domain of chartimage understanding due to the distinct…

Polarity Calibration for Opinion Summarization

NAACL 2024long

Opinion summarization is automatically generating summaries from a variety of subjective information, such as product reviews or political opinions. The challenge of opinions summarization lies in presenting divergent or even conflicting opinions. We conduct an analysis of previous summarization mod…

SportsMetrics: Blending Text and Numerical Data to Understand Information Fusion in LLMs

ACL 2024long

Large language models hold significant potential for integrating various data types, such as text documents and database records, for advanced analytics. However, blending text and numerical data presents substantial challenges. LLMs need to process and cross-reference entities and numbers, handle d…

When Reasoning Meets Information Aggregation: A Case Study with Sports Narratives

EMNLP 2024main

Reasoning is most powerful when an LLM accurately aggregates relevant information. We examine the critical role of information aggregation in reasoning by requiring the LLM to analyze sports narratives. To succeed at this task, an LLM must infer points from actions, identify related entities, attrib…

DecipherPref: Analyzing Influential Factors in Human Preference Judgments via GPT-4

EMNLP 2023long main

Human preference judgments are pivotal in guiding large language models (LLMs) to produce outputs that align with human values. Human evaluations are also used in summarization tasks to compare outputs from various systems, complementing existing automatic metrics. Despite their significance, howeve…

Generating User-Engaging News Headlines

ACL 2023long

The potential choices for news article headlines are enormous, and finding the right balance between conveying the essential message and capturing the reader’s attention is key to effective headlining. However, presenting the same news headline to all readers is a suboptimal strategy, because it doe…

OASum: Large-Scale Open Domain Aspect-based Summarization

ACL 2023findings

Aspect or query-based summarization has recently caught more attention, as it can generate differentiated summaries based on users’ interests. However, the current dataset for aspect or query-based summarization either focuses on specific domains, on a relatively small scale, or contains only a few…

An Efficient Combinatorial Optimization Model Using Learning-to-Rank Distillation

AAAI 2022technical

Recently, deep reinforcement learning (RL) has proven its feasibility in solving combinatorial optimization problems (COPs). The learning-to-rank techniques have been studied in the field of information retrieval. While several COPs can be formulated as the prioritization of input items, as is commo…

Salience Allocation as Guidance for Abstractive Summarization

EMNLP 2022main

Abstractive summarization models typically learn to capture the salient information from scratch implicitly.Recent literature adds extractive summaries as guidance for abstractive summarization models to provide hints of salient content and achieves better performance.However, extractive summaries a…

Skills Regularized Task Decomposition for Multi-task Offline Reinforcement Learning

NeurIPS 2022accept

Reinforcement learning (RL) with diverse offline datasets can have the advantage of leveraging the relation of multiple tasks and the common skills learned across those tasks, hence allowing us to deal with real-world complex problems efficiently in a data-driven way. In offline RL where only offli…

Toward Unifying Text Segmentation and Long Document Summarization

EMNLP 2022main

Text segmentation is important for signaling a document’s structure. Without segmenting a long document into topically coherent sections, it is difficult for readers to comprehend the text, let alone find important information. The problem is only exacerbated by a lack of segmentation in transcripts…

StreamHover: Livestream Transcript Summarization and Annotation

EMNLP 2021main

With the explosive growth of livestream broadcasting, there is an urgent need for new summarization technology that enables us to create a preview of streamed content and tap into this wealth of knowledge. However, the problem is nontrivial due to the informal nature of spoken language. Further, the…
