Large language models (LLMs) are AI systems that process and comprehend natural language, much like humans do. They are trained on vast corpora of text data and learn to predict the likelihood of a word appearing in a given context. In this article, we explore the different types of anaphora, or pronoun resolution, in LLMs, specifically focusing on definite and non-definite anaphora. We also discuss the challenges of dealing with non-identity anaphora, such as bridging and event anaphora, which require further theoretical work.
The authors begin by explaining that LLMs are trained on large corpora of text data, which allow them to learn complex connections between words and phrases. They use probability distributions to capture the statistical patterns of word co-occurring in data, making them distributional language models. However, despite their successes, LLMs often face challenges when dealing with non-identity anaphora, which are not resolved through simple reference resolution.
The authors then delve into the different types of anaphora, including definite and non-definite anaphora. Definite anaphora refers to the resolution of pronouns that have a clear reference in the context, while non-definite anaphora involves resolving pronouns with multiple potential references. The authors acknowledge that dealing with non-identity anaphora is challenging and require further theoretical work.
To better understand the complexities of anaphora resolution, the authors use analogies such as a group of students reading books and learning from them, or a sailor navigating through rough seas. They also provide a visual representation of how the discourse relation between pronouns and their referents can be evaluated through a bag-of-words diagram and transformed into a partial quantum circuit (PQC).
The authors conclude by highlighting the importance of understanding anaphora resolution in LLMs, particularly when dealing with non-identity anaphora. They emphasize that this area requires further theoretical work to develop more accurate and efficient models for anaphora resolution. By advancing our understanding of anaphora resolution, we can improve the performance of LLMs and enhance their ability to comprehend complex language structures.
