Utilities for document similarity and reference extraction for research papers
Both utilities expect input in the form of text files. If you have a directory
of pdf files, you can convert them using pdftotext on linux. You should use
the -raw switch to make sure that text in two columns is not garbled. To
convert all pdf files in the current directory to txt, outputting with the same
filename, just with a .txt extension, use
find . -type f -name *.pdf -exec pdftotext -raw {} \;Alternatively, you can use pdfminer, a python utility which should give
similar results.
