Discovering
Detecting link rot for a given URL is difficult using automated methods. If a URL is accessed and returns an HTTP 200 (OK) response, it may be considered accessible, but the contents of the page may have changed and may no longer be relevant. Some web servers also return a soft 404, a page returned with a 200 (OK) response (instead of a 404 that indicates the URL is no longer accessible). Bar-Yossef et al. (2004) developed a heuristic for automatically discovering soft 404s.

Famous quotes containing the word discovering:
“This is really the common mentality of prisoners: they read with great attention all the articles that deal with illnesses and send away for treatises and “be your own doctor” or “emergency treatments” and end up by discovering that they have at least 300 or 400 illnesses, whose symptoms they are experiencing.”
—Antonio Gramsci (1891–1937)
“The secret of biography resides in finding the link between talent and achievement. A biography seems irrelevant if it doesn’t discover the overlap between what the individual did and the life that made this possible. Without discovering that, you have shapeless happenings and gossip.”
—Leon Edel (b. 1907)
“License my roving hands, and let them go
Before, behind, between, above, below.
O my America! my new-found-land,
My kingdom, safeliest when with one man manned,
My mine of precious stones, my empery,
How blest am I in this discovering thee!
To enter in these bonds is to be free;
Then where my hand is set, my seal shall be.”
—John Donne (1572–1631)
