value A measure of how closely a given object
file , {web page }, database {record }, etc .) matches a user 's
search for information .
The relevance {algorithms } used in most large web {search
engines } today are based on fairly simple word -occurence
measurement : if the word "daffodil " occurs on a given page ,
then that page is considered relevant to a {query } on the word
daffodil "; and its relevance is quantised as a factor of the
number of times the word occurs in the page , on whether
daffodil " occurs in title of the page or in its META
keywords , in the first {N } words of the page , in a heading ,
and so on ; and similarly for words that a {stemmer } says are
based on "daffodil ".
More elaborate (and resource -expensive ) relevance algorithms
may involve thesaurus (or {synonym ring }) lookup ; e .g . it
might rank a document about narcissuses (but which may not
mention the word "daffodil " anywhere ) as relevant to a query
on "daffodil ", since narcissuses and daffodils are basically
the same thing . Ditto for queries on "jail " and "gaol ", etc .
More elaborate forms of thesaurus lookup may involve
multilingual thesauri (e .g . knowing that documents in Japanese
which mention the Japanese word for "narcissus " are relevant
to your search on "narcissus "), or may involve thesauri (often
auto -generated ) based not on equivalence of meaning , but on
word -proximity , such that "bulb " or "bloom " may be in the
thesaurus entry for "daffodil ".
Word spamming } essentially attempts to falsely increase a web
page 's relevance to certain common searches .
