Leveraging social data with semantics
0 likes482 views
This document discusses using semantic web technologies for social network analysis. It describes how social network data can be represented using ontologies like FOAF, SIOC, and relationship to form semantic social graphs. Classic social network analysis metrics like in-degree and betweenness centrality can then be computed on these graphs using SPARQL queries extended with social network analysis functions. Global semantic graphs can also be constructed by linking different domain ontologies and user data from social networks and bookmarks. Some bridges already exist between semantic web and mobile/enterprise applications.
