The proposed mechanism of context-aware service selection and...

  • Serendipitous Recommendations Through Ontology-Based Contextual Pre-filtering

    Publikacja

    Context-aware Recommender Systems aim to provide users with better recommendations for their current situation. Although evaluations of recommender systems often focus on accuracy, it is not the only important aspect. Often recommendations are overspecialized, i.e. all of the same kind. To deal with this problem, other properties can be considered, such as serendipity. In this paper, we study how an ontology-based and context-aware...

    What defines excellent lighting design for humans and animals? The answer to the above question is more than com­plex. It is not enough nowadays to design a project to make it aesthetically pleasing. Nor is it sufficient to create nicely lit environments, or simply to achieve the light levels required by the lighting norms or stan­dards. With the new scientific research of the last few de­cades that relates directly or indirectly...

    We discuss ellipticity property within the linear couple-stress elasticity. In this theory, there exists a deformation energy density introduced as a function of strains and gradient of macrorotations, where the latter are expressed through displacements. So the couple-stress theory could be treated as a particular class of strain gradient elasticity. Within the micropolar elasticity, the model is called Cosserat pseudocontinuum...
