|
We have been specialists in offering web crawling and data scraping services for the last few years. We use diverse platforms ranging from Java and PHP to VC++ and C# to create customized crawling solutions to provide you the data you require.
What does web crawling do? Web crawling is a way of running programs or scripts which access various websites to capture all or specific data from them. Depending on the target websites this could be a trivial task or a complex one. All search engines have spiders (another name for a web crawler) which go through the web and gather data from them. These results are then stored, filtered and indexed to provide search results for the search engine. We, at TrueLogic, create crawlers to capture data from a single website or thousands of websites, depending on the requirements. We have crawled major search engines, the largest directory site in the world, leading sites related to various industries or domains. Our objective is to automate the data extraction to provide you with the required data in the shortest possible time Why do you need a specialized crawling service Web crawling is not simply a matter of capturing website data in the fastest time possible. There are lots of factors to consider like: - Speed restrictions - Crawl too fast and the target site may block you out. Crawl too slow and it might take forever to get the data - Methodology - Some jobs require a brute force crawling application , others require a browser based crawling where pages have to be dynamically manipulated to extract rhe data. - Authentication and Cookies - Some sites require user login and authentication or the existence of certain data in cookies before they will let you access their content. These things need to be handled by the crawling application. - Simulated geographical access - In some cases, the crawler needs to act like several people are accessing the content from different parts of the world , in order to bypass content access limitations. This requires setting up proxies at various points in the globe and using them concurrently.
TrueLogic has over 15 years of experience with diverse technologies and platforms both in development and crawling and that brings an enormous leverage to the table. |
