Discovering similar Twitter accounts using semantics [article]

Gerasimos Razis, Ioannis Anagnostopoulos
2015 arXiv   pre-print
Towards this direction, we introduce a methodology for discovering and suggesting similar Twitter accounts, based entirely on their disseminated content in terms of Twitter entities used.  ...  The more common entities are found in the messages of two different accounts, the more similar, in terms of content or interest, they tend to be.  ...  In Section 6 we evaluate and discuss the results of the case study, and we further evaluate our methodology against subjective ratings from 22 evaluators.  ...
