Toward this goal, we design a new technique to efficiently build and cluster all the ego-nets of a graph in parallel (note that even just building the ego-nets efficiently is challenging on large networks). Our experimental findings are quite compelling: at a microscopic level it is easy to detect high quality communities.<\/jats:p>\n          <jats:p>Leveraging on this fact we, then, develop new features for friend suggestion based on co-occurrences of two nodes in different ego-nets' communities. Our new features can be computed efficiently on very large scale graphs by just analyzing the neighborhood of each node. Furthermore, we prove formally on a stylized model, and by experimental analysis that this new similarity measure outperforms the classic local features employed for friend suggestions.<\/jats:p>","DOI":"10.14778\/2856318.2856327","type":"journal-article","created":{"date-parts":[[2016,2,1]],"date-time":"2016-02-01T14:10:31Z","timestamp":1454335831000},"page":"324-335","source":"Crossref","is-referenced-by-count":46,"title":["Ego-net community mining applied to friend suggestion"],"prefix":"10.14778","volume":"9","author":[{"given":"Alessandro","family":"Epasto","sequence":"first","affiliation":[{"name":"Brown University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Silvio","family":"Lattanzi","sequence":"additional","affiliation":[{"name":"Google, New York"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vahab","family":"Mirrokni","sequence":"additional","affiliation":[{"name":"Google, New York"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ismail Oner","family":"Sebe","sequence":"additional","affiliation":[{"name":"Google, Mountain View"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahmed","family":"Taei","sequence":"additional","affiliation":[{"name":"Google, Mountain View"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sunita","family":"Verma","sequence":"additional","affiliation":[{"name":"Google, Mountain View"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2015,12]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1145\/2527231"},{"key":"e_1_2_1_2_1","volume-title":"Social Networks","author":"Adamic L.
