The success of artificial neural networks in language processing tasks has underscored the need to understand how they accomplish their behavior, and, in particular, how that behavior is supported by their internal vector representations. Probing classifiers, which are often used to address this question, rely on a strong, and arguably questionable, assumption: if a classifier can decode a particular piece of information from a vector, we can conclude that that piece of information affects the model&#39;s behavior. My talk will present two methods that go beyond this paradigm. The first method, AlterRep, modifies a contextualized representation such that it encodes a particular value of a linguistic feature (e.g., whether it’s in an embedded clause), and examines how that perturbation affects the model’s behavior. Using this method, I will show that syntactic information can be decoded from all layers of BERT, but only plays a functional role in a subset of those (the middle layers). The second, DISCOVER, aims to identify linear compositional structure in the vector: it tests the hypothesis that the vector can be fully decomposed into a sum of symbol-representing vectors (filler-role bindings). This hypothesis is borne out to a remarkable extent for networks trained on highly compositional tasks, and to a lesser extent for BERT’s embeddings.

CogSci 2024

The 46th Annual Meeting of the Cognitive Science Society presents the latest research across cognitive science and highlights the theme of Cognition in Context.

The success of artificial neural networks in language processing tasks has underscored the need to understand how they accomplish their behavior, and, in particular, how that behavior is supported by their internal vector representations. Probing classifiers, which are often used to address this question, rely on a strong, and arguably questionable, assumption: if a classifier can decode a particular piece of information from a vector, we can conclude that that piece of information affects the model's behavior. My talk will present two methods that go beyond this paradigm.

The Association for Computational Linguistics (ACL) is the premier international scientific and professional society for people working on computational problems involving human language, a field often referred to as either computational linguistics or natural language processing (NLP). 

Artificial intelligence in the form of natural language processing has a pivotal role in increasing the communication rate for users of Augmentative and Alternative Communication (AAC) technologies. However, communication rates remain prohibitively slow. Research at Dundee University has highlighted the importance of participatory design, focusing on language development and the role that NLP can play to support different aspects of communication. With reference to how different AI technologies can impact communication, the need for a paradigm shift in the design of interfaces will be demonstrated.

Participatory Interface Design for Intelligent Augmentative and Alternative Communication Technologies

Human evaluation of modern high-quality machine translation systems is a difficult problem, and there is increasing evidence that inadequate evaluation procedures can lead to erroneous conclusions. While there has been considerable research on human evaluation, the field still lacks a commonly accepted standard procedure. As a step toward this goal, we propose an evaluation methodology grounded in explicit error analysis, based on the Multidimensional Quality Metrics (MQM) framework. We carry out the largest MQM research study to date, scoring the outputs of top systems from the WMT 2020 shared task in two language pairs using annotations provided by professional translators with access to full document context. We analyze the resulting data extensively, finding among other results a substantially different ranking of evaluated systems from the one established by the WMT crowd workers, exhibiting a clear preference for human over machine output. Surprisingly, we also find that automatic metrics based on pre-trained embeddings can outperform human crowd workers. We further discuss the impact of this study on both the WMT metric task, and the general MT task. We will close the talk by showcasing research that benefits from the new evaluation methodology: Minimum Bayes Risk Decoding with neural metrics significantly outperforms beam search decoding in expert-based human evaluations while the previous human evaluation standards using crowd-workers set both decoding strategies on par with each other.

A journey of MT research: Why it is crucial to work on human evolution

Most work on scholarly document processing assumes that the information processed is trustworthy and factually correct. However, this is not always the case. There are two core challenges, which should be addressed: 1) ensuring that scientific publications are credible -- e.g. that claims are not made without supporting evidence, and that all relevant supporting evidence is provided; and 2) that scientific findings are not misrepresented, distorted or outright misreported when communicated by journalists or the general public. In this talk, I will present some first steps towards addressing these problems, discussing our research on exaggeration detection of scientific claims and on scientific fact checking.

Automatically Detecting Scientific Misinformation

In this talk I will give an overview of our work on fact extraction and verification. I will first introduce the first fact extraction and verification shared task on unstructured information (text) from Wikipedia and how we constructed the first large-scale dataset for it. I will then discuss how we incorporated structured inference to achieve improved robustness while maintaining state-of-the-art accuracy in fact verification. Following this, I will describe our work on correcting factual errors in claims. I will conclude this talk by presenting our recent dataset and shared task on fact extraction and verification on both structured (tables) and unstructured (tables) information.

Fact-checking as a conversation

Federated Optimization in NLP

Federated learning for industrial systems

A pressing challenge in current dialogue systems is to successfully converse with users on topics with information distributed across different modalities. Previous work in multi-turn dialogue systems has primarily focused on either text or table information. In more realistic scenarios, having a joint understanding of both is critical as knowledge is typically distributed over both unstructured and structured forms. In this talk, I will present a new dialogue dataset, HybriDialogue, which consists of crowdsourced natural conversations grounded on both Wikipedia text and tables. The conversations are created through the decomposition of complex multihop questions into simple, realistic multiturn dialogue interactions. We conduct several baseline experiments, including retrieval, system state tracking, and dialogue response generation. Our results show that there is still ample opportunity for improvement, demonstrating the importance of building stronger dialogue systems that can reason over the complex setting of information-seeking dialogue grounded on tables and text. I will also briefly mention a few related studies on dialogue research from the UCSB NLP Group.

HybriDialogue: A Conversational AI Benchmark Grounded on Tabular and Textual Dana

This talk will focus on how the Omilia Cloud Platform® leverages the notion of Dialog Act in order to solve real-life use cases in task-oriented dialog systems for call centers. We will address the challenge of completing tasks efficiently, achieving high KPIs and integrating with a call center, while at the same time building and maintaining a flexible conversational NLU system.

Dialog Management for Conversational Task-Oriented Industry Solutions

Big pre-training models (such as BERT and GPT3) have demonstrated excellent performances on various NLP tasks. Instruction tuning and prompting have enabled these models to shine in low-resource settings. The natural question is “Will big models solve dialog tasks?” This talk will first go through big models’ impact on several sub-topics within dialog systems (e.g. social chatbots, task-oriented dialog systems, negotiation/persuasion dialog systems, continue learning in dialog systems, multilingual dialog systems, multimodal dialog systems, deployable dialog systems, etc) and then follow up with the speaker's own interpretations of the challenges remaining and possible future directions.

Will Big Models Solve Dialog Systems?

Advances in core NLP capabilities have enabled an extensive variety of scenarios where conversational AI provides real value for companies and customers alike. Leveraging lessons learned from these successes to applying the technology in the humanitarian context requires an understanding of both the potential for impact and risk of misuse.

In this talk, we'll discuss how to leverage conversational AI to scale impact for audiences in the humanitarian sector while earning and maintaining trust with the adopters of the technology and with the people they impact.
