Marvin – A tool for semantic annotation released


Marvin – semantic annotator

We created Marvin, an semantic text annotation tool that uses external resources such as DBPedia and WordNet to annotate semantically text. Marvin is built in java and can be used as a standalone application or as a library.

Marvin semantic annotator already has a lot of knowledge, which will make anyone probably depressed and therefore we gave him a name with reference to “Hitchhikers guide to the Galaxy” depressed robot.



Basically, Marvin queries the sources he can for the definitions about words in inputed text. He uses some NLP transformations in order to obtain as much knowledge as possible. For DBPedia he uses unigram and bigrams, while wordnet queries only with single words.
