Vectors for Topics: The use of Topical Vector Spaces in Epistemic Logics
This paper proposes a novel approach to modeling topics in epistemic logics by using vector spaces instead of traditional semi-lattices. Drawing inspiration from large language models, the authors argue that vectors offer a more fine-grained and philosophically satisfying representation of topic relationships, allowing for the modeling of degrees of similarity, vagueness, and disagreement. The work reconstructs a logic of conditional hyperintensional belief, replacing its semi-lattice of topics with a vector space, and demonstrates soundness and completeness. Future work includes extending this framework to multi-agent logics, fuzzy logic, and Bayesian techniques for topics.

Vector Spaces as Topic Structures
The paper introduces vector spaces as a natural and advantageous representation for topics, moving beyond traditional semi-lattices. Vectors allow for modeling semantic relationships, degrees of similarity, and provide both fine-grained (individual vectors) and coarse-grained (subspaces) levels of topic representation. This approach is motivated by their successful application in large language models (LLMs) to represent word meanings and their semantic relations.
Hyperintensionality in Epistemic Logics
Hyperintensionality is the concept that logically and modally equivalent sentences are not always interchangeable, particularly in contexts like belief. Topic-Sensitive Intentional Modals (TSIMs) address this by incorporating a topic component into their semantics. The vector space approach provides a robust structure for these topics, ensuring the distinctness of truth conditions and topic, which is crucial for 2C semantics.
LLM Insights for Logical Semantics
The motivation for using vector spaces for topics comes directly from their application in LLMs, where vectors effectively capture semantic relations between words. While LLM vector spaces are complex and often opaque, their ability to represent similarities and differences between meanings makes them ideal for formalizing topic relations in logic. This demonstrates a practical, empirically-backed foundation for the proposed logical semantics.
Reconstructing Topic Containment
In the reconstructed logic, topic containment is formalized: the topic of B is contained in the topic of A when the vector representing B lives in the smallest standard subspace containing the vector for A. This allows for a two-level understanding of topics: individual vectors for fine-grained representation and subspaces for coarse-grained inclusion, while maintaining compatibility with existing semi-lattice properties for topic fusion.

Reduction in Topic Ambiguity
By leveraging vector spaces, the model can quantify the 'distance' between topics, leading to a significant reduction in ambiguity compared to traditional Boolean or semi-lattice representations.

Case Study: Advanced Customer Support AI
Problem: A major financial institution struggled with its AI-powered customer support chatbot misinterpreting user intent due to subtle topic shifts, leading to irrelevant responses and customer frustration. The existing topic model was based on a rigid semi-lattice structure.
Solution: Implemented a vector-based topic model, allowing the AI to understand nuances and degrees of topic relevance. User queries were mapped to vectors, and the system identified not just 'on-topic' but 'close-enough-to-topic' responses.
Outcome: Improved first-contact resolution by 15% and reduced customer complaints related to misinterpretation by 30%. The AI now proactively suggests relevant follow-up questions based on the vector proximity of related topics.
