When Peculiarity Makes a Difference: Object Characterisation in Heterogeneous Information Networks

A central task in heterogeneous information networks (HIN) is how to characterise an entity, which underlies a wide range of applications such as similarity search, entity profiling and linkage. Most existing work focus on using the main features common to all. While this approach makes sense in set...
