given css class and extends a given vocabulary with a term consisting with the text content of the html class tag. Additionally, the term is included into the semantic facet of the document. This allows the creation of faceted search to documents without the pre-creation of vocabularies; instead, the vocabulary is created on-the-fly, possibly for use in other crawls. If any of the term scraping for a specific vocabulary is successful on a document, this vocabulary is excluded for auto-annotation on the page. To use this feature, do the following: - create a vocabulary on /Vocabulary_p.html (if not existent) - in /CrawlStartExpert.html you will now see the vocabularies as column in a table. The second column provides text fields where you can name the class of html entities where the literal of the corresponding vocabulary shall be scraped out - when doing a search, you will see the content of the scraped fields in a navigation facet for the given vocabulary
