WordSelectionFunction

is an option for WordCloud and other functions that specifies which words to use.

Details

  • The following settings can be given for WordSelectionFunction:
  • Automatican automatic selection
    True&no filtering
    fan arbitrary selection function f
  • The function f takes a word as the first argument and that word's weight as its second argument:
  • #Word or #1the word
    #Weight or #2the word's weight

Basic Examples  (1)

Select strings based on their length:

Wolfram Language code: WordCloud[RandomWord["KnownWords", 100], WordSelectionFunction -> (StringLength[#] < 6&)]

Applications  (2)

Make a word cloud with the Wolfram Language symbols ranked by their documentation usage:

Wolfram Language code: data = WolframLanguageData[All, {"Name", EntityProperty["WolframLanguageSymbol", "Frequencies", {"Corpus" -> "WolframDocumentation"}]}];
Wolfram Language code: WordCloud[data]

Use WordSelectionFunction to pick only symbols with the NumericFunction attribute:

Wolfram Language code: WordCloud[data, WordSelectionFunction -> Function[MemberQ[Attributes[#Word], NumericFunction]]]

Select the countries based on their name length:

Wolfram Language code: data = CountryData[#, "Population"] -> CountryData[#, "Name"]& /@ CountryData[];
Wolfram Language code: WordCloud[data, WordSelectionFunction -> (StringLength[#] == 6&)]

Include the element weight in the selection:

Wolfram Language code: WordCloud[data, WordSelectionFunction -> Function[{country, population}, StringTake[country, 1] == "G" && population < Quantity[10^7, "People"]]]
