Determinants of sociability include obvious measures such as the number of participants in a community, the number of messages per unit of time, members’ satisfaction, and some less obvious mea...

Separating Wheat from the Chaff - A Relationship Ranking Algorithm

We address the problem of ranking relationships in an automatically constructed knowledge graph. We propose a probabilistic ranking mechanism that utilizes entity popularity, entity affinity, and support from text corpora for the relationships. Results obtained from preliminary experiments on a standard dataset are encouraging and show that our proposed ranking mechanism can find more informati...
