-1. DESCRIPTION
-This tool annotates a document with URLs of corresponidng entities.
-
-Linker parses annotated tokens/groups of tokens to spot expressions which 
-have to be described by mentioned URL.
-URLs are taken from semantic graph of connected resources.
-
-Linker accepts *.ccl file with annotations of following type:
-  - mwe (multi-word expressions)
-  - ne (named entities)
-  - wsd (word sense disambiguation - annottated with syn_id)
-
-Note: in current version, multi-word expressions (including named entity)
-have precedence over disambiguated words. It's the case when 
-word annotated with wsd have been included in multi-word expression.
-Then in many cases sesnse of this single word will differ from sense
-of whole expression.
-
-As a result, *.ccl document is returned with included URL annotations.
