Extending AutoTag support
Developers perform this task.
Currently AutoTag supports Articles and Blog Posts. To extend this functionality to additional content types, a developer must create an Augmentation
of that type, implementing the AutoTaggable
interface.
When implementing AutoTaggable
, override the getAutoTaggableText()
method to return the appropriate text to be submitted to the Amazon Comprehend service.
The following example shows the ArticleAutoTaggableAugmentation
implementation. It returns text from the article's headline, subheadline, and body fields.
public class ArticleAutoTaggableAugmentation extends Augmentation<Article> implements AutoTaggable { @Override public String getAutoTaggableText() { Article article = getOriginalObject(); return Optional.ofNullable(article.getHeadline()).orElse("") + " " + Optional.ofNullable(article.getSubHeadline()).orElse("") + " " + Optional.ofNullable(article.getBody()) .filter(RichTextBody.class::isInstance) .map(body -> ((RichTextBody) body).getRichText()) .map(text -> text.replace("<br/>", " ")) .map(RichTextUtils::stripRichTextElements) .map(RichTextUtils::richTextToPlainText) .orElse(""); } }
