Showing in \ref{fig:LCS}, the dataset is generated as following steps: 
(1) split document into sentences. 
(2) enumerate all unused sentence pairs in a document, and generate their normalized copies. 
(3) calculate their LCS from normalized copies by SuffixAutomaton \url{https://github.com/NAME_1/SuffixAutomaton}, a pair which has a long enough LCS is a similar pair.  
(4) sample similar pairs into dataset.  
(5) a sentence which length exceeds NAME_2 length will be randomly cropped \cite{izacard2022unsupervised} in dataloader.
