Báo cáo khoa học: "Word Maturity: Computational Modeling of Word Knowledge" docx

... paradigm called word meaning maturity which tracks the degree of knowledge of each word at dif- ferent stages of language learning. We pre- sent a computational algorithm for estimating word maturity, ... including: o Words known by most children in grade 2 o Words known by 40-80% of children in grade 2 o Words known by 40-80% of children in grade 6 o Words known by...

... kinetic parameters of Y10F could not be measured at pH 9.0 due to enzyme instability. At pH 8.0 Y10F showed a k cat of 0.55 and K m of 47.2 (compared to a k cat of 3.5 and a K m of 24.9 in the wildtype ... formed and broken). Thus, the calculated effect of rotation of Asp142 on the pK a of Glu144 only gives an indication of what may happen to the acidity of Glu144. Althoug...

... instance of this method based on identity of words in the variation contexts, so-called variation n-grams, successfully detects a variety of errors in the WSJ corpus. The usefulness of the notion of ... assign- ment for a word is dependent on the context of that word. The second takes into account that natural languages favor the use of local dependencies over non-local ones....

Thus, the goal of maximizing the parsing coverage while minimizing the ... results of the technique on the basis of two sets of unseen test data. In section 5 we discuss system engineering issues to accommodate the proposed technique, i.e., integration...
