*This is the first in a series of posts from Dr Bernhard Haslhofer, one the recipients of the [DM2E Open Humanities Award](http://openhumanitiesawards.org).*

In my previous [blog post](https://blog.okfn.org/2013/05/08/announcing-the-open-humanities-award-winners/) I announced that we will use the Open Humanities Award to integrate [Maphub’s Semantic Tagging feature](http://maphub.github.io/) into [Annotorious](http://annotorious.github.io/), which is a light-weight JavaScript annotation tool that works for online images, including zoomable images – such as digitized maps. The semantic tagging feature will give people the opportunity to enrich their annotations with links to entities in existing knowledge graphs such as [Freebase](http://www.freebase.com/) or DBPedia (http://dbpedia.org/About), but also to customized knowledge contexts that reflect institution-specific needs. If for instance, someone uses Annotorious for a collection of images relating to automotive history, it should be possible to define a knowledge context reflecting concepts from that domain (e.g., cars, people related to car racing and technology, etc.).

Technically, this means we have build two things: (i) a plug-in for Annotorious that provides semantic tagging functionality on the user interface, and (ii) a lightweight tag recommendation service that proposes possibly related entities (semantic tags) from a given knowledge context.

[Rainer](http://twitter.com/aboutgeo), who is the mastermind behind Annotorious, is working on the plug-in and set up a [first beta demo](http://annotorious.github.io/demos.html). In the next step we will focus on the tag recommendation service and its integration with the front-end and expect a first beta by the end of July.
