Epistemic Skills: Logical Dynamics of Knowing and Forgetting

X Liang, YN Wáng - arXiv preprint arXiv:2410.22763, 2024 - arxiv.org
We present a type of epistemic logics that encapsulates both the dynamics of acquiring
knowledge (knowing) and losing information (forgetting), alongside the integration of group …

Field Knowledge as a Dual to Distributed Knowledge: A Characterization by Weighted Modal Logic

X Liang, YN Wáng - arXiv preprint arXiv:2407.00687, 2024 - arxiv.org
The study of group knowledge concepts such as mutual, common, and distributed
knowledge is well established within the discipline of epistemic logic. In this work, we …

Epistemic Logic over Similarity Graphs: Common, Distributed and Mutual Knowledge

X Liang, YN Wáng - arXiv preprint arXiv:2310.00264, 2023 - arxiv.org
In this paper, we delve into the study of epistemic logics, interpreted through similarity
models based on weighted graphs. We explore eight languages that extend the traditional …

Characterization of Similarity Metrics in Epistemic Logic

X Liang, YN Wáng - Pacific Rim International Conference on Artificial …, 2024 - Springer
The comprehension of similarity metrics lags behind that of distance metrics. This study aims
to address this disparity by synthesizing the properties of similarity metrics and examining …

[PDF][PDF] Epistemic logics over weighted graphs

X Liang, YN Wáng - Logics for New-Generation AI, 2022 - collegepublications.co.uk
In this paper we introduce weighted graphs and as a special case of it, similarity graphs,
which can be used to model similarity between epistemic objects. We study epistemic logics …

Epistemic Logic via Distance and Similarity

X Liang, YN Wáng - Pacific Rim International Conference on Artificial …, 2022 - Springer
A weighted graph extends a standard Kripke frame for modal logic with a weight on each of
its edges. Distance and similarity measures can be imposed so that the edges stand for the …
