Abstract:

 

Conventional data is typically considered as a collection of independent observations identically distributed in the space of possible attribute values.  In reality data are packed-full with all sorts of relationships themselves maintaining their own attribute values. For instance, in a database of books, these books are considered independent and when querying this database or recommending a book only the attribute values are taken into account. Yet, there are various relationships between books that could be considered such as co-authorship, friendship of readers, etc. These relationships have significant influence thus should be reflected upon in data analysis. Much data is nowadays in this form of networked entities such as in biology, criminology, sociology, marketing, finance, etc. Studying information networks is also known as social network analysis.  Social network analysis is a field of study attempting to understand and measure relationships between entities in networked information.  We introduce social network analysis, illustrate some practical examples drawn from different application domains, examine some work done in this area, and present relevant challenges.
