Random Walk Integration and Remove unnecessary codes coming from SORBET

[sefeoglu]

Hi,

• Keep only data preprocessing codes

• Modify them only for data cleaning and preparation

• Keep only Random Walk algorithm codes from SORBET on our repo and run it on the cleaned data

• High precision matcher: Exact string matching algorithm

The code for the random walk, can be found at: https://github.com/Lama-West/SORBET_ISWC23/blob/main/src/batch_loaders/random_walk.py

The Random walks are used in SEBMatcher's batch loaders here: https://github.com/Lama-West/SORBET_ISWC23/blob/main/src/batch_loaders/MLM_batch_loader.py#35 and here: https://github.com/Lama-West/SORBET_ISWC23/blob/main/src/batch_loaders/pair_alignment_batch_loader.py#L24
