Data Extraction and Scraping Services

Crawling usually refers to dealing with large data-sets where you develop your own crawlers (or bots) which crawl to the deepest of the web pages. Data scraping on the other hand refers to retrieving information from any source (not necessarily the web). Its more often the case that irrespective of the approaches involved, we refer to extracting data from the web as scraping (or harvesting) and thats a serious misconception.

1. Scraping data does not necessarily involve the web. Data scraping could refer to extracting information from a local machine, a database, or even if it is from the internet, a mere Save as link on the page is also a subset of the data scraping universe. Crawling on the other hand differs immensely in scale as well as in range. Firstly, crawling = web crawling which means on the web, we can only crawl data. Programs that perform this incredible job are called crawl agents or bots or spiders (please leave the other spider in spidermans world). Some web spiders are algorithmically designed to reach the maximum depth of a page and crawl them iteratively (did we ever say scrape?).

2. Web is an open world and the quintessential practising platform of our right to freedom. Thus a lot of content gets created and then duplicated. For instance, the same blog might be posted on different pages and our spiders dont understand that. Hence, data de-duplication (affectionately dedup) is an integral part of data crawling. This is done to achieve two things- keep our clients happy by not flooding their machines with the same data more than once, and saving our own servers some space. However, dedup is not necessarily a part of data scraping.

Summary:

While making a comparison between web scraping tools and services, you may arrive at the conclusion that the services are much more beneficial, reliable, and efficient than the major tools.
