Description
Chapter two of the book N. Marwan & C.L. Webber, "Recurrence Quantification Analysis. Theory and Best Practices" discusses how the Kolmogorov entropy can be connected to and computed from Recurrence matrices. See 2.2 and 2.3.3 .
A method for estimating KS entropy has long been requested from ChaosTools, see https://github.com/JuliaDynamics/ChaosTools.jl/issues/6 .
Would be cool to implement the algorithm in this package!

Research direction
Start with sections 2.2 and 2.3.3 of the cited book and the linked ChaosTools issue #6 to define the requested Kolmogorov–Sinai entropy method from recurrence matrices. The issue names no source file or test, so first locate the relevant RecurrenceAnalysis.jl entry point; done means the algorithm is implemented in this package.
