However, when the coverage of the most frequent 1,000, 1,500, and 1,996 headwords in the lists was compared, the New-GSL provided the highest coverage. The GSL had the worst performance using both criteria. Pedagogical and methodological implications related to second language (L2) vocabulary...

This Google Ngram, which charts word frequency use from Google’s vast electronic library of books, shows that Teilhard is mentioned much more frequently than the major evolutionary scientists of his day. This is despite the fact that Teilhard has been largely forgotten by evolutionary scientists....
We do not use the full tf-idf measure because we process single sentences, where it is likely that the term frequency (tf) is 1. Because we use the reference sentences, the idf scores remain the same for all systems evaluated on a specific test set. For unknown words in the reference ...
However, the following parameters are mostly independent of the transfer bandwidth and DRAM’s bus frequency. Consequently, the number of required cycles increases with newer memories. Memory modeling can be correspondingly simplified by associating fixed latency for each of the parameters that impact ...
The measure of weakness here is the contact frequency, which corresponds to the weight of links in the network, whereas the measure to grasp structural holes uses network topology, known as Burt’s constraint, which represents the absence of a structural hole13. Burt’s constraint counts the ...
Search boxes providing simple keyword-based search are insufficient when users have complex information needs or are unfamiliar with a collection, for exam
We then compare the lists of pairs of interacting drugs across sources in order to determine the shared coverage between NDF-RT and DrugBank, as well as the coverage of the reference set by both sources. We characterize the differences among DDI sets in terms of drug classes. We also ...
where the term frequency [Math Processing Error]TF(t,d) is the number of occurrences of term t in document d, and the inverse document frequency [Math Processing Error]IDF(t) of a term t models the inverse of the number of documents a term occurs in, and is defined as [Math Processin...
The widely used technique for feature selection is the "bag of words" method (Da Silva et al., 2014), which involves breaking down text into words, treating each word as a feature, and counting its frequency of occurrence while disregarding co-occurrence (Wartena et al., 2010). ...
