MarcXimiL is a free, flexible, fully standards-compliant and efficient bibliographic similarity analysis framework.

Similarity analyses may be set up at all levels of the process, run in batch or through the API. Options include:

* the order of comparisons between and within collections
* for each field, the selection of a parsing function
* for each field, the selection of a comparison function amongst a wide selection: vectorial (Dice, Jaccard, Salton's cosine), probabilistic (OKAPI BM25), Levenshtein based, Shingling, Authors, Date, and others.
* the global record similarity strategy (integration of fields similarities)
* the output format (XML, spreadsheet)
* thresholds at different levels
