Digital Classicist London & Institute of Classical Studies seminar 2015

Friday June 12th at 16:30, in Room 348, Senate House, Malet Street, London WC1E 7HU

Livecast at Digital Classicist London YouTube channel.

Pelagios is a community-driven initiative that facilitates better linkage between online resources documenting the past, based on the places that they refer to. Our member projects are connected by a vision of a world in which the geography of the past is every bit as interconnected, interactive and interesting as the present. Each project represents a different perspective on our shared history, whether expressed through text, map or archaeological record. But as a group we believe that the combination of all of our contributions is enormously more valuable than the sum of its parts.

In this presentation, we outline Recogito, a Web-based tool we have developed specifically for most efficient annotation of both texts and maps. Recogito features several work areas, each dedicated to different stages of the geo-annotation workflow: an image annotation area to mark up and transcribe place names on map or manuscript scans, a text annotation area to demarcate place names in digital text, and a geo-resolution area, where the identified (and transcribed) place names are mapped to a gazetteer (and, thus, to geographical coordinates). Recogito also provides basic features for managing documents and their metadata, as well as functionality for viewing and downloading annotation data and usage statistics. Editing functionality is limited to registered users. However, data downloads and basic overview information is also available for access to the public. Our own production instance of Recogito is hosted at The tool as such, however, is Open Source software (available from the Pelagios project’s GitHub repository, which makes it possible to set up additional instances of Recogito for personal or institutional use.


The seminar will be followed by wine and refreshments.
