Selecting The Most Highly Correlated Pairs Within A Large Vocabulary
نویسنده
چکیده
Occurence patterns of words in documents can be expressed as binary vectors. When two vectors are similar, the two words corresponding to the vectors may have some implicit relationship with each other. We call these two words a correlated pair. This report describes a method for obtaining the most highly correlated pairs of a given size. In practice, the method requires computation time, and memory space, where is the number of documents or records. Since this does not depend on the size of the vocabulary under analysis, it is possible to compute correlations between all the words in a corpus.

Feature selection based on word–sentence relation1
Feature selection proved to improve both the speed and the quality of classification. Methods such as mutual information, information gain or chi-square are all based on the joint distribution of classes and words; there exist only a few methods which exploit contextual information for feature selection. We introduce an algorithm based on word and word pair frequencies that reduces both vocabul...

متن کاملInteractive Clustering Techniques for Selecting Speaker-Independent Reference Templates for Isolated Word Recognition
It is demonstrated that clustering can be a powerful tool for selecting reference templates for speaker-independent word recognition. We describe a set of clustering techniques specifically designed for this purpose. These interactive procedures identify coarse structure, fine structure, overlap of, and outliers from clusters. The techniques have been applied t a large speech data base consisti...
متن کاملWord Type Effects on L2 Word Retrieval and Learning: Homonym versus Synonym Vocabulary Instruction
The purpose of this study was twofold: (a) to assess the retention of two word types (synonyms and homonyms) in the short term memory, and (b) to investigate the effect of these word types on word learning by asking learners to learn their Persian meanings. A total of 73 Iranian language learners studying English translation participated in the study. For the first purpose, 36 freshmen from an ...
