An Approach to Design and Implement Parallel Web Crawler

摘要

Indefinite cyberspace crawling is an architecture for a parallel searching process occurred in various websites using internet. Web crawler is defined as a software or program which traverses the Web and downloads web documents in an automated manner. It’s depends on the type of questions asked by the user. The pertinence of Web Crawler in the field of web search of this architecture is to capably and successfully crawl the current set of publicly index able web pages to amplify the download rate on shrinking the parallelization. Now a days web grows is becoming extremely difficult to recover the substantial or significant portion of the Web using in a single method. There are many search engines like-Google, Bing, Yandex, Search Encrypt etcetera runs various threads in parallel to perform the above job, so that the download rate gets exploited. The requirement of web crawler is to gather and verify the data in order to store the huge amount of data in such a speed on the Web requires parallel computing. It is definite as a program or as a software that traverses the Website and downloads web documents in a systematic, robotic method. We are going to discuss about the relevance of the Web Crawler. The topic about web crawler is the option to do web search and a small examination on Web Crawler on different problematic fields or domains in web search as mention here.
