Wisniewski and Murphy collected ratings on familiarity (participants indicated phrases they had "heard or seen before"), plausibility (on a scale of 1 to 7 with 1 being very weird and 7 being very plausible), and frequency of phrase occurrence based on number of hits from the Google Internet search engine (similar to the phrase-frequency measure used in the present study).
According to Google Ngram Viewer, which tracks the frequency a phrase is used over time, "sleep deprivation" is a term of relatively recent origin.
In contrast to participant-based ratings such as meaningfulness and association, all other ancillary measures were based on either text corpora (for LSA, word frequency and phrase frequency) or surface properties (number of letters).
In a database of 18 major newspapers, the relative frequency of phrases like "race prejudice" has declined by 60percentt since 1980 (as far back as the online records go), while the frequency of "racism" has doubled.
Nevertheless, there is an increase in the number of contributions related to ATE and an interesting tendency to use contrasting corpora and domain stoplists, even though most contributions only use frequency, noun phrases, and morphosyntactic patterns.
The influence on meaningfulness ratings of the following five factors was examined: association, LSA distance, letter length, phrase frequency, and summed word frequency (Table 3).
Phrase frequency analysis (the occurrence frequency of multiword technical phrases) provides the pervasive technical themes of the topical databases of interest, and phrase proximity analysis provides the relationships among the pervasive technical themes.
Using the random model expected three-phrase combination frequencies were calculated as the product of the frequency of each phrase.
The much lower frequency of this phrase in regard to President Bush implies that Bush is first in line, is the legitimate heir to the nomination of his party, whereas Kerry for some reason is not.
