Zero-rating and network effects

patterns and variations in native and non-native interlanguage pragmatic rating: effects of rater training, intercultural proficiency, and self-assessment

although there are studies on pragmatic assessment, to date, literature has been almost silent about native and non-native english raters’ criteria for the assessment of efl learners’ pragmatic performance. focusing on this topic, this study pursued four purposes. the first one was to find criteria for rating the speech acts of apology and refusal in l2 by native and non-native english teachers...

Rating E-mail Personality at Zero Acquaintance*

Electronic media are pervasive in daily communication. But how well can personality traits be perceived through a short e-mail message? Working independently and under experimenter supervision, thirty judges each rated 18 short e-mail texts. These texts were written under experimental conditions by authors of known personality, who briefly described their recent activities, and were collected a...

Analysis of Movie Rating Network

The data used is MovieLens 1M from http://www.grouplens.org/node/73 which consists of 1 million ratings from 6000 users on 4000 movies. Due to huge number of nodes and edges, I only sample a small portion of the entire dataset which includes 11398 ratings from 86 users on 2154 movies during a week in 2000. Each user rates a movie using integer score ranging from 1 to 5 where larger score indica...

From Zero to Hero: How Zero-Rating Became a Debate about Human Rights

Optimization of sediment rating curve coefficients using evolutionary algorithms and unsupervised artificial neural network

Sediment rating curve (SRC) is a conventional and a common regression model in estimating suspended sediment load (SSL) of flow discharge. However, in most cases the data log-transformation in SRC models causing a bias which underestimates SSL prediction. In this study, using the daily stream flow and suspended sediment load data from Shalman hydrometric station on Shalmanroud River, Guilan Pro...
