"UMBEL Concept Plain Tagger This plain tagger uses UMBEL reference concepts to tag an input text. The OBIE (Ontology-Based Information Extraction) method is used, driven by the UMBEL reference concept ontology. By plain we mean that the words (tokens) of the input text are matched to either the preferred labels or alternative labels of the reference concepts, with the match basis denoted by color. The simple tagger is merely making string matches to the possible UMBEL reference concepts."
