Recommender Systems

Recommender Systems

Tamara Heck

Recommendation systems suggest relevant and suitable resources (such as products, music, people and tags) to a user. The goal is to predict a user’s preferences. The prediction is based on resource information (content-based) and information about users and users' social environment (collaborative filtering). Recommender services are used in many different fields, e.g. in e-commerce, social bookmarking services and music websites. The can also be used in the academic field, e.g. to suggest collaborators to target researchers, based on social infromation like publications, citations and bookmarks.
