Research in recommender systems focusses on stimulating serendipity on the user side, by suggesting items that might more likely be unexpected, potentially novel, and necessarily of value to the user. Several components of the proposed model were implemented in related work, and art and music recommendation connects to the area of computational creativity. \paragraph{{[}To add: HR.{]}}
A recommender system must come with a prepared mind \paragraph{Recommender systems.} Research in
terms of full knowledge of recommender systems focusses on stimulating serendipity on the
user side, by suggesting items
in the search space, that might more be unexpected, novel, and
of valuable to the
user's partial knowledge user.

If a pattern is found, it is used to \textbf{bridge} between items that are known and valuable to the user, and those that are potentially unexpected. As an example, \cite{Sugiyama2011} connects users with divergent interests, while \cite{Onuma2009} weight items stronger that bridge between topical clusters.
Recommender systems have to cope with a
dynamic world \textbf{dynamic world} of user preferences and new items that are introduced to the system. The imperfect knowledge about the user's preferences and interests represents perhaps the strongest dimension of
chance. \textbf{chance}. Determining the
value \textbf{value} of an item, both in terms of value for the user and unexpectedness, is of paramount importance. While standardized measures such as the $F_1$-score or the (R)MSE
)are are used to determine the accuracy of an evaluation in terms of preferred items in the user's history, there is no common agreement on a measure for serendipity yet \cite{ Murakami2008, Adamopoulos2011, McCay-Peet2011}.
