In order to understand the reasons that lead individuals to practice physical activity, researchers developed the Motives for Physical Activity Measure-Revised (MPAM-R) scale. In 2010, a translation of MPAM-R to Portuguese and its validation was performed. However, psychometric measures were not acceptable. In addition, factor scores in some sports psychology scales are calculated by the mean o...

Mitkov and Ha (2003) and Mitkov et al. (2006) offered an alternative to the lengthy and demanding activity of developing multiple-choice test items by proposing an NLP-based methodology for construction of test items from instructive texts such as textbook chapters and encyclopaedia entries. One of the interesting research questions which emerged during these projects was how better quality dis...

Executive functions depend on the ability to represent relations between objects and events, and the prefrontal cortex provides the neural substrate for this capacity. Patients with probable Alzheimer's disease (AD) and control participants were administered measures of working memory and reasoning that varied systematically in their relational complexity. AD patients showed impairment on reaso...

BACKGROUND Urinary tract infection (UTI) is a common condition in primary care. Patient-reported outcome measures (PROMs) are crucial in the evaluation of interventions to improve diagnosis, treatment and prognosis of UTI. The aim of this study was to identify an existing condition-specific PROM to measure symptom severity, bothersomeness and impact on daily activities for adult patients with s...

This article describes how mathematical content items and formulæ are processed, retrieved, and accessed in ActiveMath. Central to the retrieval and access is a search tool which allows for searching text, attributes, relations and formulæ, and presenting items. The search tool has been evaluated according to the standard measures of precision and recall as well as for usability. We report resu...

We introduce the measures share, coincidence and dominance as alternatives to the standard itemset methodology measure of support. We also redefine the confidence measure in this context. An itemset is a group of items bought together in a transaction. The support of an itemset is the ratio of transactions in which an itemset appears to the total number of transactions. The share of an itemset ...

The symmetric EM algorithm is proposed for probabilistic latent semantic analysis in collaborative filtering. The algorithm allows to reveal the latent interest profiles of both users and items, then to easily construct high-quality similarity measures of all required types: user–user, item–item, and item–user. The advantage of the proposed approach is that different profiles are consistent to ...
