Mining Local Specialties for Travelers by Leveraging Structured and Unstructured Data
Advances in Multimedia, Volume 2012, Issue 1, 2012., 2012 Recently, many local review websites such as Yelp are emerging, which have greatly facilitated people′s daily life such as cuisine hunting. However they failed to meet travelers′ demands because travelers are more concerned about a city′s local specialties instead of the city′s high ranked restaurants. To solve this problem, this paper presents a local
