Methods for Legal Citation Prediction in the Age of LLMs: An Australian Law Case Study

no code implementations9 Dec 2024 Ehsan Shareghi, Jiuzhou Han, Paul Burgess

In recent years, Large Language Models (LLMs) have shown great potential across a wide range of legal tasks.

Agent S: An Open Agentic Framework that Uses Computers Like a Human

1 code implementation10 Oct 2024 Saaket Agashe, Jiuzhou Han, Shuyu Gan, Jiachen Yang, Ang Li, Xin Eric Wang

We present Agent S, an open agentic framework that enables autonomous interaction with computers through a Graphical User Interface (GUI), aimed at transforming human-computer interaction by automating complex, multi-step tasks.

Strategies for Improving NL-to-FOL Translation with LLMs: Data Generation, Incremental Fine-Tuning, and Verification

no code implementations24 Sep 2024 Ramya Keerthy Thatikonda, Jiuzhou Han, Wray Buntine, Ehsan Shareghi

Research in symbolic logical reasoning explored FOL generation using state-of-the-art LLMs (i. e., GPT-4) to produce FOL translations of natural language (NL) statements, but errors in translation are usually not the focus.

Towards Uncertainty-Aware Language Agent

no code implementations25 Jan 2024 Jiuzhou Han, Wray Buntine, Ehsan Shareghi

We present the Uncertainty-Aware Language Agent (UALA), a framework that orchestrates the interaction between the agent and the external world using uncertainty quantification.

POSQA: Probe the World Models of LLMs with Size Comparisons

1 code implementation20 Oct 2023 Chang Shu, Jiuzhou Han, Fangyu Liu, Ehsan Shareghi, Nigel Collier

Embodied language comprehension emphasizes that language understanding is not solely a matter of mental processing in the brain but also involves interactions with the physical and social environment.

Reward Engineering for Generating Semi-structured Explanation

1 code implementation15 Sep 2023 Jiuzhou Han, Wray Buntine, Ehsan Shareghi

Semi-structured explanation depicts the implicit process of a reasoner with an explicit representation.

PiVe: Prompting with Iterative Verification Improving Graph-based Generative Capability of LLMs

1 code implementation21 May 2023 Jiuzhou Han, Nigel Collier, Wray Buntine, Ehsan Shareghi

We show how a small language model could be trained to act as a verifier module for the output of an LLM~(i. e., ChatGPT, GPT-4), and to iteratively improve its performance via fine-grained corrective instructions.

Self-supervised Graph Masking Pre-training for Graph-to-Text Generation

1 code implementation19 Oct 2022 Jiuzhou Han, Ehsan Shareghi

Large-scale pre-trained language models (PLMs) have advanced Graph-to-Text (G2T) generation by processing the linearised version of a graph.

Decoder Text Generation

Generating Diverse Descriptions from Semantic Graphs

1 code implementation INLG (ACL) 2021 Jiuzhou Han, Daniel Beck, Trevor Cohn

Text generation from semantic graphs is traditionally performed with deterministic methods, which generate a unique description given an input graph.
