A Methodical Study Of Web Crawler
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 11
Abstract
World Wide Web (or simply web) is a massive, wealthy, preferable, effortlessly available and appropriate source of information and its users are increasing very swiftly now a day. To salvage information from web, search engines are used which access web pages as per the requirement of the users. The size of the web is very wide and contains structured, semi structured and unstructured data. Most of the data present in the web is unmanaged so it is not possible to access the whole web at once in a single attempt, so search engine use web crawler. Web crawler is a vital part of the search engine. It is a program that navigates the web and downloads the references of the web pages.Search engine runs several instances of the crawlers on wide spread servers to get diversified information from them. The web crawler crawls from one page to another in the World Wide Web, fetch the webpage, load the content of the page to search engine’s database and index it. Index is a huge database of words and text that occur on different webpage. This paper presentsa systematic study of the web crawler. The study of web crawler is very important because properly designed web crawlers always yield well results most of the time.
