We present an emotion model based on social tags, which is built upon an automatically generated lexicon that describes emotions by means of synonym and antonym terms. Using this model we develop a number of methods that transform social tag-based item profiles into emotion-oriented item profiles. We show that the model’s representation of a number of basic emotions is in accordance with the we...

Description of test and diagnostic standards The 6 item CRAFFT test (table 1) was administered verbally and the responses to the 6 yes/no questions were recorded. 2 scales were administered concurrently for criterion validity. The first diagnostic standard was the 17 item Substance Use/Abuse Scale from the Problem Oriented Screening Instrument for Teenagers (POSIT), which assesses substance rel...

The construct validity of a 10-item scale oriented to measure traditional culture, the Organizational Culture Scale of Artifacts, was analyzed under the hypothesis of unidimensionality. Confirmatory factor analysis took into account the method effects associated with reverse-worded items. Based on the data from one-half of a sample of 926 participants (79.8% male; M age = 33.4 yr., SD = 12.8), ...

Aggregated recommendation refers to the process of suggesting one kind of items to a group of users. Compared to user-oriented or item-oriented approaches, it is more general and, therefore, more appropriate for cold-start recommendation. In this paper, we propose a random forest approach to create aggregated recommender systems. The approach is used to predict the rating of a group of users to...

The two-dimensional discrete bin-packing problem (2BP ) consists in minimizing the number of identical rectangles used to pack a set of smaller rectangles. This problem is NP-complete. It occurs in industry if pieces of steel, wood, or paper have to be cut from larger rectangles. It belongs to the family of cutting and packing (C & P) problems, more precisely Two-Dimensional Single Bin Size Bin...

Adopting a ‘cross-cultural indigenous approach’ (CCI), we attempted a conceptual analysis of cultural conceptions of SWB in terms of individual-oriented SWB (ISWB) and socially oriented SWB (SSWB) views. Also incorporating findings from our previous qualitative studies, a culturally balanced and fair measurement, The Individual-oriented and Socially oriented cultural conceptions of SWB Scales (...

In this paper we present an emotion computational model based on social tags. The model is built upon an automatically generated lexicon that describes emotions by means of synonym and antonym terms, and that is linked to multiple domain-specific emotion folksonomies extracted from entertainment social tagging systems. Using these cross-domain folksonomies, we develop a number of methods that a...
