Detecting Domain Experts
•The detection of Experts is based on the
concepts they mention inside the tweets.
•Simple concepts do not show expert knowledge
•Very specific concepts are an indicator for expert
knowledge
•A person which talks about the sun, moon and stars is
not necessary an astronomer, a person mentioning
concepts like Irregular Galax, Magellanic Cloud or
Supernova Remnant is more likely an expert in the
area.
