WebTTS is a trouble ticketing system written in PERL5 designed for businesses that need to track problems in their network.

Trouble Ticketing Systems are used by businesses and individuals to track problems in some type of product or service.

Nouns, verbs, adjectives and adverbs are grouped into sets of cognitive synonyms (synsets), each expressing a distinct concept.
