Data excavation isn't screen-scraping. I cognize that whatsoever empire in the legroom may dispute with that statement, but they're certainly two about categorically deviating concepts.

In a nutshell, you can nation it this way: screen-scraping allows you to get information, where information excavation allows you to examine rumour. That's a beautiful big simplification, so I'll luxuriant a bit.

The occupancy "screen-scraping" comes from the old digital computer last life where population worked on computers next to lush and black screens containing single textual matter. Screen-scraping was nearly new to passage characters from the screens so that they could be analyzed. Fast-forwarding to the web global of today, screen-scraping now furthermost readily refers to extracting substance from web sites. That is, computing device programs can "crawl" or "spider" finished web sites, pull out information. People ofttimes do this to size things similar examination buying engines, depository web pages, or but download paper to a table so that it can be filtered and analyzed.

Data mining, on the other hand, is delimited by Wikipedia as the "practice of without thinking probing enlarged stores of aggregation for patterns." In another words, you simply have the data, and you're now analyzing it to learn helpful property going on for it. Data production oft involves loads of convoluted algorithms supported on applied math methods. It has zero to do near how you got the facts in the early function. In facts excavation you just effort nearly analyzing what's just location.

The trouble is that group who don't cognize the occupancy "screen-scraping" will try Googling for anything that resembles it. We encompass a digit of these status on our web spot to relief specified folks; for example, we created pages eligible Text Data Mining, Automated Data Collection, Web Site Data Extraction, and even Web Site Ripper (I say "scraping" is sort of same "ripping"). So it presents a bit of a problem-we don't needfully deprivation to bear on a idea (i.e., screen-scraping = notes production), but we as well have to use terminology that race will in actuality use.
