Corpus Terms

Corpus Terms is a table view of term frequencies in the entire corpus.

Use it with a Jane Austen corpus or with your own corpus.

Overview

The table view shows the following three data columns by default:

  • Term: this is the term in the corpus
  • Count: this is the frequency of the term in the corpus
  • Trends: this is a sparkline graph that shows the distribution of relative frequencies across documents in the corpus (if the corpus contains more than one document); you can hover over the sparkline to see finer-grained results

Additional columns are available by clicking on the down arrow that appears in the right side of a column header:

  • Relative: this is the relative frequency of the term in the corpus (calculated by dividing the raw frequency by the total number of terms in the corpus and multiplying by 1 million). Sorting by count and relative should produce the same results, the relative frequencies might be useful when comparing to another corpus.
  • Comparison: this is the relative frequency of the term in the corpus compared to the relative frequency of the same term in a comparison corpus; to specify the comparison corpus, click the options icon and specify the comparison corpus to use
  • Peakedness: this is a statistical measure of how much the relative frequencies of a term in a corpus are bunched up into peaks (regions with higher values where the rest are lower)
  • Skew: this is a statistical measure of the symmetry of the relative frequencies of a term across the corpus

By default, the most frequent terms in the corpus are shown.

Corpus Terms with the Works of Jane Austen. You can also use Corpus Terms with your own corpus.

Options

You can specify terms by typing a query into the search box and hitting enter (see Search for more advanced searching capabilities).

Clicking on the options icon allows you to define a set of stopwords to exclude – see the Stopwords for more information.

You can also specify a comparison corpus by copying and pasting a comparison corpus ID (or selecting one of the pre-defined ones). The comparison is used for relative frequencies. You also need to show the "Comparison" column in the grid.

Spyral

To use Corpus Terms in Spyral you can use the following code as a starting point. Modify the config object to modify the visualization.

let config = {
    columns: null, // 'term', 'rawFreq', 'relativeFreq', 'relativePeakedness', 'relativeSkewness', 'comparisonRelativeFreqDifference', 'distributions'
    comparisonCorpus: null, // An existing corpus to be used for comparison purposes. 
    dir: null, // The direction in which to sort the results: 'asc' or 'desc'
    maxBins: null, // The maximum number of bins to use for distributions in Trend.
    query: null, // A query or array of queries (queries can be separated by a comma). For query syntax, see the search documentation.
    sort: null, // The column to sort the results by
    stopList: null, // A comma-separated list of words, a named list or a URL to a plain text list, one word per line. By default this is set to 'auto' which auto-detects the document's language and loads an appropriate list (if available for that language). Set this to blank to not use the default stopList.
    termColors: null, // Which term colors to show in the grid. By default this is set to 'categories' which shows the term color only if it's been assigned by a category. The other alternatives are 'terms' which shows all terms colors, and '' or undefined which shows no term colors.
};

loadCorpus("austen").tool("corpusterms", config);

Please see Tools.CorpusTerms for more information about configuration.
