In the paper "Discovering Relevant Topics using DBPedia providing non-obvious recommendations" they have used skos:broader property and dcterms:subject property.

In my task given the word I want to identify the topic of it. For example, given the word; 'suport vector machine', I want to identify topics from it such as classification algorithm, machine learning etc.

However, I could not find the properties mentioned in the paper (skos:broader and dcterms:subject) in the relevant DBpedia pages: http://dbpedia.org/page/Support_vector_machine

Please let me know how I can achieve my task (retrieving topics from keywords) using DBpedia properties (or using any other knowledgebase)?

I am happy to provide more examples if needed.
