In the Library and Information Science Commuity, we distinguish between a
thesaurus and a classification system on the basis of prsence or absence of
a 'notation system'. A thesaurus is also structured but has no notation but
a classification has a notation( some numbering system)..
The functions are almost similar..But in a physical Library world
Classification system serve the pupose of shelf arrangement and thus act as
a location symbol as well.Both are used for structuring information.Both
help retrieve relevant items...
