Example of usage

You can add the keyword extractor widget to a Group field in semantics.json like so:

  "name": "keywordExtractorGroup",
  "label": "Keyword extractor",
  "type": "group",
  "widget": "KeywordExtractor",
  "keywordExtractor": {
    "buttons": {
      "contentText": "extractKeywords",
      "customKeywords": "parseKeywordsComma"
    },
    "keywords": "keywords"
  },

Here,

• the widget is added by "widget": "KeywordExtractor" (you need to add the widget as a library dependency as well, of course),
• one button to perform slightly intelligent keyword extraction from a text in a Text field (optionally using a Textarea widget) is set to be the field with the name contentText,
• one button to perform simple keyword extraction from a comma separated list of keywords in a Text field is set to be the field with the name customKeywords,
• the Text field that is supposed store the keywords is set to be field with the name keywords.

A complete Group field could look like this in semantics.json:

{
  "name": "keywordExtractorGroup",
  "label": "Keyword extractor",
  "type": "group",
  "importance": "low",
  "expanded": true,
  "widget": "KeywordExtractor",
  "keywordExtractor": {
    "buttons": {
      "contentText": "extractKeywords",
      "customKeywords": "parseKeywordsComma"
    },
    "keywords": "keywords"
  },
  "fields": [
    {
      "name": "contentText",
      "label": "Content",
      "description": "Reference text block for users.",
      "type": "text",
      "importance": "medium",
      "optional": true,
      "widget": "textarea"
    },
    {
      "name": "customKeywords",
      "description": "Add custom keywords of your choice, separated by comma.",
      "type": "text",
      "label": "Add keywords",
      "importance": "low",
      "optional": true
    },
    {
      "name": "keywords",
      "description": "Below listed keywords will available for users.",
      "label": "Keywords",
      "type": "text",
      "importance": "medium",
      "optional": true,
      "maxLength": 5000
    }
  ]
}
