GAP addresses two primary concerns related to online resources: discovery and usability, using the ancient world as a test case. No one person is going to able to find all the ancient places referenced in large text corpora (like the one million plus Google Books corpus): for that you need a helping hand. GAP is developing a search engine (based on the Edinburgh Geoparser), which automatically finds (“geotags”) references to ancient places in a text and then links (“georesolves”) them to a gazetteer. In order to visualize the results in meaningful ways, GAP uses a single-screen application called GapVis with various components to help the reader navigate through a text geospatially.
