abstract |
DBpedia has become one of the major sources of structured knowledge extracted from
Wikipedia. Such structures gradually re-shape the representation of Topics as new
events relevant to such topics emerge. Such changes make evident the continuous evolution
of topic representations and introduce new challenges to supervised topic classification
tasks, since labelled data can rapidly become outdated. Here we analyse topic changes
in DBpedia and propose the use of semantic features as a more stable representation
of a topic. Our experiments show promising results in understanding how the relevance
of features to a topic changes over time. |
