AntCorGen is a freeware corpus generation tool. The app lets you search for documents in the PLOS ONE research database via search queries and/or subject category browsing, and decide which sections (e.g., title, abstract, introduction) of these documents should be stored. AntCorGen then accesses the database, downloads the sections, and saves each one as a text file in an
appropriate folder. AntCorGen can also analyzes the different parts of speech (e.g., adjectives, verbs) of words in the files and clusters similar sentences into sub-groups. These sub-groups will show similar patterns of language use.
