The term Web scraping refers to the process or technique of extracting information from various websites using specially coded software programs. This software program stimulates the human exploration of the Web through various methods that include embedding Web browsers like the Mozilla and the Internet Explorer browsers or implementing HyperText Transfer Protocol (or more popularly known as HTTP). Web scraping focuses on extracting data such as product prices, weather data, public records (Unclaimed Money, Sex Offenders, Criminal records, Court records), stock price movements etc. in a local database for further use.
Although the method of web scraping is still a developing process, it favors more practical solutions that are based on already-existing applications and technologies as opposed to its more ambitious counterparts that require more complicated breakthroughs and knowledge to work. Here are just some of the various Web scraping methods available:
We at ITSYS Solutions specialize in developing anonymous and non-intrusive web scraping tools that are able to scrape dynamically generated data from the private web as well as scripted content. Our customized website scraping programs begin by identifying and specifying as input, a list of URLs that define the data that is to be extracted. The web scraping program then begins to download this list of URLs and the corresponding HTML text.
The extracted HTML is text is thereafter parsed by the application to identify and store the needed information in a data format of your choice. Embedded hyperlinks / images that are encountered can be either followed or ignored, depending on requirement (Deep-WebData extraction).
