  Abstract This study explores the acquisition of internal orderings of adjective-addedKorean classifier phrases. When a classifier phrase includes an adjective, twoconstraints rule out impossible orderings: adjectives occur before the nounthey modify, and no modifying elements can intervene between the numberand the classifier. An acceptability judgment experiment was conducted withnative Korean-speaking adults and children to test their knowledge of thetwo constraints. The results indicate that, like adults, the children know thetwo constraints, disallowing impossible orderings. The results also show aranking in the preference of the possible orderings. We suggest that semanticcompositionality (i.e., A and N together) can account for the preferred internalorderings of Korean adjective-added classifier phrases. [Collapse]

  Abstract This study investigates the relationship between anticipatory behaviors and inhibitory controls in L2 learners using a visual world paradigm. Thirty-four college students with high-intermediate English proficiency participated in an eye-tracking experiment and a flanker task. The eye-tracking results show that the participants predict upcoming words, thereby incrementally processing English sentences in a similar manner to L1 speakers. The eye-movement patterns indicate that they actively made use of combinatory information extracted from subject and verb and real-world knowledge. The results from a flanker task, as a measurement of inhibitory controls, reveal that the flanker effect of accuracy, but not the flanker effect of RT, is signficantly correlated with anticipatory processing. That is, the participants who responded to the flankers more accurately were better and faster in predicting the target object. In short, our study supports the constraint-based accounts for sentence processing in L2 suggesting that inhibitory controls as an index of cognitive functions can be another constraint on predictive sentence processing.

• Effects of Visual, Lexical, and Contextual Factors on Word Recognition in Reading Korean Sentences

  Abstract In order to assess the role of visual, lexical, and contextual information on word identification during Korean sentence reading, a self-paced reading experiment was conducted. It was found, with regard to word length variables, that the number of syllables and the number of visual features affected reading times significantly, but the other sub-lexical units (i.e., phonemes and letters) did not. The findings suggest that when taking internal structure variations into account, the relevant processing unit in Korean in the context of sentence is the syllable. In addition, the main effects of both word frequency and predictability on reading time were significant, respectively; however, the interaction between these two variables was not. The results imply that Korean word recognition during sentence reading is affected by word frequency and word predictability, additively. [Collapse]
• Finding Sentiment Dimension in Vector Space of Movie Reviews: An Unsupervised Approach
  by Youngsam Kim & Hyopil Shin
  J. CS. 2017, 18(1), 85-102;
  Abstract This study suggests an unsupervised method to find sentiment orientations of the words in Korean movie reviews. The orientations are represented as real values on a sentiment domain, which is derived from high-dimensional vector space for the movie reviews. To search for the dimension, the Point- wi...

  Abstract This study suggests an unsupervised method to find sentiment orientations of the words in Korean movie reviews. The orientations are represented as real values on a sentiment domain, which is derived from high-dimensional vector space for the movie reviews. To search for the dimension, the Point- wise Mutual Information is first used to select a set of words that are close to common modifiers; The phrases comprised of these words often form good/ bad associations (e.g., “good acting”, “terrible acting”). A neural language model (Word2Vec) is then used to calculate the point-wise similarity distances between the chosen words and, dimensionality reduction algorithms (e.g., PCA, MDS) are employed to find the axis of the sentiment orientations. Finally, the performance of our method is measured by unsupervised classification of the two movie reviews based on the orientation values. According to the results, the best accuracy achieves 66% and 76% for the two datasets. [Collapse]
