Predefined Page Facts

If input text comes from a web page, RL3 enables to make use of page metadata in conditions with applying predefined page facts.

Every page serving as an input for an RL3 annotator can have the following information:

URL

Page URL, e.g. http://europe.yamaha.com/en/products/proaudio/

domain

E.g. the domain for http://europe.yamaha.com/en/products/proaudio/ will be "europe.yamaha.com".

domain_name

A top-level domain, e.g. http://europe.yamaha.com/en/products/proaudio/ has a domain name "yamaha.com".

domain_basename

The "base name" of a domain, i.e. a top-level domain without a zone (e.g. .com, .ru, .co.uk) or hosting info (.narod.ru). For a page http://europe.yamaha.com/en/products/proaudio/, domain_basename is "yamaha". For a page http://http://www.zorallabs.com/, domain_basename is "zorallabs".

languages

Page languages. If a page uses more than one language, several values will be available for the fact.

E.g. to annotate only for pages with a German text:

  annotation
       Product=product
  search text
       {product={german_specific_product_pattern}}
  if
       each xx in languages
            match xx german

In the example above, a predicate would be executed only if all the languages in the page match \Agerman\Z , i.e. a page has only one languages that equals "german". If it is enough to check that at least one of the languages on the page is German, try the following (either with 'match' or 'search'):

  annotation
       Product=product
  search text
       {product={german_specific_product_pattern}}
  if
       any xx in languages
            search xx german

title

Page title, is extracted from an HTML markup (i.e. text from the element <title>...</title>). E.g. for a page http://zorallabs.com/ will be "Home Page - Zoral Labs".

description

Page description, is extracted from an HTML markup (i.e. text from the element <meta name="description">...</meta>).

pathway

So-called "breadcrumbs" (http://en.wikipedia.org/wiki/Breadcrumb_(navigation) ) often used for navigation on corporate websites. For a page http://zorallabs.com/company/management-team will have a value "Home › Company › Management Team"
