| Definition |
- Screen Scraping
v.
The act of capturing data from a system or program by snooping
the contents of some display that is not actually intended
for data transport or inspection by programs. Around 1980
this term referred to tricks like reading the display memory
of a smart terminal through its auxiliary port. Nowadays
it often refers to parsing the HTML in generated web pages
with programs designed to mine out particular patterns of
content. In either guise screen-scraping is an ugly, ad-hoc,
last-resort technique that is very likely to break on even
minor changes to the format of the data being snooped.
- Deep Web/Hidden Web
n.
The Deep Web (or Hidden Web) comprises all information that
resides in autonomous databases behind portals and information
providers' web front-ends. Web pages in the Deep Web are
dynamically-generated in response to a query through a web
site's search form and often contain rich content. A recent
study has estimated the size of the Deep Web to be more
than 500 billion pages, whereas the size of the "crawlable"
web is only 1% of the Deep Web (i.e., less than 5 billion
pages). Even those web sites with some static links that
are "crawlable" by a search engine often have
much more information available only through a query interface.
Unlocking this vast deep web content presents a major research
challenge. |
