N-grams
The N-grams tab includes details of sequences of phrases and their frequency within HTML page content.
To enable this functionality, ‘Store HTML / Store Rendered HTML’ needs to be enabled under ‘Config > Spider > Extraction’. A URL or a selection of URLs can then be highlighted in the top window, and the n-grams tab will populate with aggregated n-gram data.
The left-hand side displays aggregated n-grams for all highlighted URLs. The filters can be adjusted to display a range of n-grams, from 1-gram to 6-gram.
The right-hand side displays the details of the URL the selected n-grams are on. In the example above, the 2-gram ‘broken links’ is highlighted and is shown to be on 3 pages.
