Duplicated stems and you will stems shorter following one or two letters was indeed in the end removed acquiring a sample out-of stems we used in the study.
Finally (results in Figure step three), i opposed the essential difference between American English and you may United kingdom English courses inside the about three other research establishes (as well as temper conditions): content-free terms, utilizing the range of the content-totally free terminology available with Huges mais aussi al. , the same arbitrary stems utilized for Figure dos, as well as the variety of the new one hundred prominent metropolitan agglomerations from the industry (off that features terminology such as for example Tokyo, Karachi, and you can Berlin.

A: Frequencies try normalized with the cumulative number of your top ten most frequent words for each and every season. Correlations towards big date series included in the research (normalized on the yearly matter out-of “the”) is actually statistically extreme (Pearson’s to have line data, and for smoothed studies. In the two cases and you can ). B: Frequencies is stabilized using the total matters of just one-g for every seasons. As well as in this instance correlations for the go out show found in the research are mathematically tall (Pearson’s getting line studies, as well as for smoothed investigation.

Getting a year , because of the count of word “the” regarding the corpus while the matters of your own WordNet terms representing one of many half a dozen believed aura versions, i computed a feeling get ( ) as follows: (1) i.e. a mood get is largely the common normalized volume along the sensed vibe terms and conditions. To help you contrast different varieties of moods effortlessly, immediately following computing the feeling ratings for your band of decades (1900 to help you 2000), i translated them to the -score similar ( ), using: (2) where and you will signify the brand new suggest and you can basic departure of your own temper scores over the believed set of decades.
