Taxonomy plays an important role in many applications by organizing domain knowledge into a hierarchy of is-a relations between terms. Previous works on the taxonomic relation identification from text corpora lack in two aspects: 1) They do not consider the trustiness of individual source texts, which is important to filter out incorrect relations from unreliable sources. 2) They also do not co...

The concept of teacher efficacy has received significant attention in educational contexts in the recent years and has been empirically probed at 2 levels: individual teacher efficacy and collective teacher efficacy. Having their origins in the social cognitive theory, teacher and collective efficacy perceptions are quite distinct constructs, each affecting educational decisions and student ach...

We consider general heterogeneous ensembles of phase oscillators, sine coupled to arbitrary external fields. Starting with the infinitely large ensembles, we extend the Watanabe–Strogatz theory, valid for identical oscillators, to cover the case of an arbitrary parameter distribution. The obtained equations yield the description of the ensemble dynamics in terms of collective variables and cons...
