I am currently working on an M.Phil thesis which is focusing on topic modelling 19th century journals. The journals in question are science, literature and antiquities based. I have extracted the text using OCR. I need to build a dictionary of terms with which I can spell check my corpus. To do this, I need to find a clean scientific corpus or word list that I can build the dictionary from. edit - English language corpus required (sorry for any ambiguity)
I have looked at Archer but it's got a lot of OCR errors / non-textual content in the word list. I have also looked at The Art Corpus, but it is too modern.
Any ideas welcome.
