Core algorithms used and modified in TableDataExtractor have originally been developed by Embley et al. This is the MIPS (Minimum Indexing Point Search) algorithm that is used to find the row/column headers and the data region, as well as algorithms for prefixing header cells. Also, some of the examples in this documentation are based on examples from Embley et al:

Embley, D.W., Krishnamoorthy, M.S., Nagy, G., and Seth, S. (2016) Converting heterogeneous statistical tables on the web to searchable databases. *Int. J. Doc. Anal. Recognit.*, *19* (2), 119–138.

Algorithms for duplicating spanning cells and extending headers, that are used in TableDataExtractor, have been developed by Nagy and Seth:

Nagy, G., and Seth, S. (2017) Table headers: An entrance to the data mine. *Proc. - Int. Conf. Pattern Recognit.*, 4065–4070.

The algorithm for converting html files to Numpy arrays has been modified from John Rico:
