Feature-Frequency–Adaptive On-line Training for Fast and Accurate Natural Language Processing
Fast Accurate NaturalLanguage Processing
2015/9/14
Training speed and accuracy are two major concerns of large-scale natural language processing systems. Typically, we need to make a tradeoff between speed and accuracy. It is trivial to improve the tr...

Suffix Arrays Compute Term Frequency Document Frequency All Substrings
2015/8/26
Bigrams and trigrams are commonly used in statistical natural language processing; this paper will describe techniques for working with much longer n-grams. Suffix arrays (Manber and Myers 1990) were ...
Extracting the Lowest-Frequency Words:Pitfalls and Possibilities
Lowest-Frequency Words Pitfalls Possibilities
2015/8/25
In a medical information extraction system, we use common word association techniques to extract side-effect-related terms. Many of these terms have a frequency of less than five. Standard word-associ...
