Not only is calculating PCA for every sentence in a document computationally complex, but the first principal component of a small number of normally distributed words in a high dimensional space is subject to random fluctuation. Their calculation of word frequencies from the unigram count of the ...

Such concepts are often complex, co-occurring with other concepts, or difficult to infer from individual words. Researchers can leverage supervised machine learning classification methods to automatically expand (systematic) manual coding onto a large number of texts. These methods infer word patterns ...
