Relation rst#definition (description_content/medium/container,description_content/medium/container)  a logical relation should be used instead of this relation
  exclusion:  circumstance  solution  elaboration  cause  effect  comparison  means  condition  otherwise  interpretation  restatement  summary  theme  contrast
  supertype:  subject_matter_rhetorical_relation (description_content/medium/container,description_content/medium/container)  connect to details for making a better description
     supertype:  rhetorical_relation (description_content/medium/container,description_content/medium/container)  main sources: the Rhetorical Structure Theory (RST) and the PENMAN ontology; DO NOT USE such fuzzy relations: instead, use relations from/to situations!
        supertype:  relation_from_description_content/medium/container (description_content/medium/container,*)
           supertype:  relation_from/to_thing_of_common_kind (*)  this type permits to categorize relations according to their signatures and hence offers (i) a concise way to set essential exclusion relations, and (ii) a systematic and easy-to-follow categorization

           supertype:  refers (?,?)  the 1st argument mentions or includes a reference to the 2nd argument, e.g., an article whose topic is a recent change in the price of oil may refer to many other things, e.g., the general state of the economy, the weather in California, the prospect of global warming, the options for alternative energy sources, the stock prices of various oil companies, etc.
              supertype:  Relation (?,?)  to specify a reference to a related resource; in WebKB, pm#relation or MORE PRECISE RELATION TYPES SHOULD BE USED INSTEAD
                 supertype:  binary_relation (?,?)  in WebKB, most relation types are binary and some have a variable number of arguments (as in KIF), hence this type is currently only specialized by types that I do not want to see as direct subtypes of pm#relation
                    supertype:  relation_with_particular_property (*)  this rather fuzzy type permits to group categorization schemes less common than those covered by the previous sibling categories
