Property-based Semantic Similarity and Relatedness for Improving Recommendation Accuracy and Diversity

Silvia Likavec, Francesco Osborne, Federica Cena
2015 International Journal on Semantic Web and Information Systems (IJSWIS)  
These measures are used in the propagation of user interest values in ontology-based user models to other similar or related concepts in the domain.  ...  The authors tested their algorithm in event recommendation domain and in recipe domain and showed that property-based propagation based on similarity outperforms the standard edge-based propagation.  ...  This propagation of user interests can be seen as a special case of spreading activation theory (Salton and Buckley, 1988) , since starting from a user interest in one domain object, it is possible to  ...

Property-Based Interest Propagation in Ontology-Based User Model [chapter]

Federica Cena, Silvia Likavec, Francesco Osborne
2012 Lecture Notes in Computer Science  
Starting from initial user feedback on an object, we calculate user interest in this particular object and its properties and further propagate user interest to other objects in the ontology, similar or  ...  We tested our approach for interest propagation with a real adaptive application and obtained an improvement with respect to IS-A-propagation of interest values.  ...  The system records implicitly the user actions, inferring from them the interest for the object the action is performed on, and uses it to incrementally create and update the user model by modifying the  ...

Selective Propagation of Social Data in Decentralized Online Social Network [chapter]

Udeep Tandukar, Julita Vassileva
2012 Lecture Notes in Computer Science  
Due to the fact that most current OSNs are centralized, people are forced to share their data with the site, in order to be able to share it with their friends, and thus they lose control over it.  ...  This paper discusses an approach for propagation of social data in a decentralized OSN so as to reduce irrelevant data among users.  ...  That is why it is desirable for the representation of user data in the user model to follow some ontology so that it could be understood and interpreted outside of the context of the application in which  ...
