Extracting and representing user interests on the social web is becoming an essential part of the web for personalization and recommendations. Such personalization is required in order to provide an adaptive web to users, where content fits their preferences, background and current interests, making the web more social and relevant. Current techniques analyze user activities on social media systems and collect structured or unstructured sets of entities representing users' interests. These sets of entities, or user profiles of interest, are often missing the semantics of the entities in terms of: popularity and temporal dynamics of the interests on the social web and abstractness of the entities in the real world.
