Data Scraping

CHASR supports data scraping, either as a standalone activity, or as part of a larger project. Data scraping is a technique where human-readable content is transferred into another format so that it may be analyzed more easily. This translation is automated using custom computer programs. CHASR staff can convert the data into a range of formats, including CSV, XML, or JSON.

Custom data and web scraping programs can process large amounts of data in a relatively short period of time. The program must be developed to extract the needed data, usually from websites or web repositories. The program also handles data cleaning, and translation of the data into the desired output format.
