[Distant Reader: distantreader.org][1] is a text mining gateway system which locally harvests/caches content you specify. It then transforms the content into plain text, performs sets of natural language processing & text mining against the text, saves the results in a number of formats, reduces the whole to a cross-platform database file, queries the database thus summarizing the collection, zips the results of the entire process into a single file, and makes the file available to you for downloading,sharing and best of all - further investigation -- "reading".
