Is He The One? Subject Identification in Topic Maps

Paper, by Robert Barta

This paper is about subject identifying in Topic Maps.

Topic Map content is about things (subjects) be they tangible things like physical objects like a particular car, or abstractions like the class ‘car’ or even homocentric concepts as ‘love’ and ‘hate’. It also includes things which only exist electronically such as online documents. As such topics are only representants: they represent (proxy) the subject; the subject itself, of course, exists outside the topic map. Equivalently, we sometimes use the phrase a subject is reified by a topic.

The problem the topic map author faces is how to connect a topic with the subject outside the map. Only to name a topic ‘Stalin’ does not necessarily mean that every other person in this universe knows exactly that we talk exactly about the Russian dictator during the second world war.

According to the Topic Map paradigm this problem is resolved using subject addresses and subject indicators. This short feature presents the options Topic Map authors have to refer to the outside world. As notation we will use XTM

Topic Maps offered the semantic flexibility that I needed in Topincs, an application with an unlimited domain. It allowed me to make statements about any subjects. Exactly what I was looking for.
