I found a problem with the dataset.
at (q_bio.qm-ann11.json -> 1807.09728v2.Adaptive_locally_linear_models_of_complex_dynamics/paragraph_17)
In the text, 9999999999 symbol is processed as a blank.
I want to know why, and please solve it.
Thanks for your question.
In order to reduce the complexity of the text, some nested entities (e.g. inline equation inside an equation) were removed (these are the footprint of those). You can treat these symbols as blank space.
