Towards Knowledgeable Foundation Models

Knowledge has been an important pre-requisite for a variety of AI applications, and is typically sourced from either structured knowledge sources such as knowledge bases and dictionaries or unstructured knowledge sources such as Wikipedia documents.

More recently, researchers have discovered that language models already possess a significant amount of knowledge through pre-training: LLMs can be used to generate commonsense knowledge and factual knowledge context for question answering. While the results are encouraging, there are still lingering questions:

Where does this knowledge come from?
How much do language models know?
Is this knowledge reliable?
If some knowledge is wrong, can we fix it?

This workshop examines the lifecycle of knowledge within language models:

(1) the emergence of knowledge through language model pre-training;
(2) injection of external knowledge;
(3) the updating and modification of knowledge;
(4) probing and generation of knowledge.

This is the 3rd workshop for Knowledgeable Foundation Model workshop. The previous workshop was hosted at KnowFM@AAAI2025 and KnowLM@ACL2024.

Call for Papers

Knowledge has been an important prerequisite for various NLP applications and is typically derived from either structured knowledge sources such as knowledge bases and dictionaries or unstructured knowledge sources such as Wikipedia documents and news articles.

It is known that language models already possess a significant amount of knowledge through pre-training: LLMs can be used to generate commonsense knowledge and factual knowledge when prompted to do so. However, beyond the surface, there are still many lingering questions such as “where the knowledge comes from”, “how do we quantify the amount of knowledge”, “is the knowledge reliable (and do LMs themselves know)”, “how can we augment LMs with domain-specific knowledge”, “how can we revise knowledge without hurting the reasoning abilities of LMs” and “how can we leverage knowledge to assist the self-correction of LMs”.

In this workshop, we want to bring together researchers who focus on different stages and different aspects (structured knowledge, unstructured knowledge, and knowledge acquired from LMs themselves) of the knowledge lifecycle to discuss the role of knowledge in the era of large language models.

Submission Topics

We welcome submissions on all topics related to knowledgable LMs, including:

Analysis of knowledge within LMs: how much they know and where that knowledge is from.
Enhancing LMs with existing knowledge sources (knowledge graphs, domain-specific databases, manuals, and rules, etc, either during training or inference).
Analyzing and improving RAG (retrieval-augmented generation) systems
Updating and editing knowledge in LMs.
Knowledge extraction and generation using LMs
Evaluation of knowledge utilization (faithfulness, truthfulness) by LMs.
Identification and mitigation of LM hallucinations, factual error correction

We will also announce a Best Paper Award at our workshop.

Submission Instructions

We welcome two types of papers: regular workshop papers and non-archival submissions. Only regular workshop papers will be included in the workshop proceedings. Review process will be double-blind. All submissions should be in PDF format following the ACL template and made through OpenReview submission portal (https://openreview.net/group?id=aclweb.org/ACL/2025/Workshop/KnowFM)

Time	Program
09:00-09:10	Opening Remarks
09:10-09:50	Keynote Speech Preslov Nakov: Towards Truly Open, Language-Specific, Safe, Factual, and Specialized Large Language Models First, we will argue for the need for fully transparent open-source large language models (LLMs), and we will describe the efforts of MBZUAI's Institute on Foundation Models (IFM) towards that based on the LLM360 initiative. Second, we will argue for the need for language-specific LLMs, and we will share our experience from building Jais, the world's leading open Arabic-centric foundation and instruction-tuned large language model, Nanda, our open-weights Hindi LLM, Sherkala, our open-weights Kazakh LLM, and some other models. Third, we will argue for the need for safe LLMs, and we will present Do-Not-Answer, a dataset for evaluating the guardrails of LLMs, which is at the core of the safety mechanisms of our LLMs. Forth, we will argue for the need for factual LLMs, we will discuss the factuality challenges that LLMs pose. We will then present some recent relevant tools for addressing these challenges developed at MBZUAI: (i) OpenFactCheck, a framework for fact-checking LLM output, for building customized fact-checking systems, and for benchmarking LLMs for factuality, (ii) LM-Polygraph, a tool for predicting an LLM's uncertainty in its output using cheap and fast uncertainty quantification techniques, and (iii) LLM-DetectAIve, a tool for machine-generated text detection. Finally, we will argue for the need for specialized models, and we will present the zoo of LLMs currently being developed at MBZUAI's IFM.
09:50-10:30	Keynote Speech Yunyao Li: Declarative to Generative: Building and Querying Enterprise Knowledge Bases Over the last 25 years -- search, knowledge graph and even large language model innovations have been adopted by consumers much before enterprises. The delay in adoption of such technologies in enterprises is largely due to two factors. First, enterprise knowledge bases vary widely based on industry verticals and even within an industry vertical by organization-specific terminology and vocabulary. Second, querying such knowledge bases needs to account for very low-tolerance enterprise users have for mistakes and hallucination. In this talk I will describe tools to build, maintain and query such knowledge bases and the evolution of these tools over two decades from declarative to generative systems.

12:15-12:25	Best Paper Award Announcement
12:25-14:10	Lunch Break
14:10-14:50	Keynote Speech Chengxiang Zhai: From Knowledgeable Foundation Models to Knowledgeable Agents: A Neurosymbolic Perspective on Knowledge Representation Foundation models acquire massive amounts of useful knowledge from both pre-training and fine-tuning, but the knowledge they encode in their parameter space is neither interpretable nor verifiable, and their behavior in applying the knowledge during inference time is unpredictable. These limitations cause concerns about their trustworthiness when they are directly used in real world applications. While much work has attempted to address those limitations via improving a foundation model itself, we argue that those limitations of foundation models are better addressed by building an agent that can augment the foundation model with a memory mechanism, regulate its behavior using a symbolic representation module, and self-improve itself over time. In this talk, we will discuss how compression of deep neural networks enables foundation models to acquire generalizable knowledge in both pre-training and fine-tuning, why the behaviors of foundation models are inherently unpredictable, and why it is necessary to build a knowledgeable agent on top of a knowledgeable foundation model and use a neurosymbolic knowledge representation to enable both trustworthiness and lifelong learning of the agent. We will conclude with some promising future directions for future research.
