TagFinder (tagfinder.herokuapp.com) is a full text search engine for OpenStreetMap tags. It uses Taginfo, translation services (German to English), a thesaurus and an adapted domain-specific semantic net.
TagFinder was developed during a semester thesis in informatics at the Geometa Lab, University for Applied Sciences Rapperswil (Switzerland). The application offers a RESTful API, is written in Python 2.7 and uses the Flask web framework. The source code is on Github.
