Web Crawler Analysis Paper

For this assignment, I was allowed to improvise on a provided base code to develop a functioning web crawler. The web crawler needed to accept a starting URL and then develop a URL frontier queue of “out links” to be further explored. The crawler needed to track the number of URLs and stop adding them once the queue had reached 500 links. The crawler needed to also extract text and remove HTML tags and formatting. The assignment instructions offered using the BeautifulSoup module to achieve those goals, which I chose to do. Finally, the web crawler program needed to report metrics including the number of documents (web pages), the number of tokens extracted and processed, and the number of unique terms added to the term dictionary.

With the advent of computer technology in 1990’s the need to search large databases was increasingly becoming vital. The search engines prior to PageRank had limitations, the then most widely used algorithm used text based indexes to provide search results on World Wide Web however had limitations of improper search results as the logic used by the search engines looked at the number of occurrences of the search word in webpage which sometimes resulted in improper search results. Another technique used during the time was based on variations of standard vector space model – i.e. search based on how recent the webpage was updated and/or how close the search terms are to the

By saving physical memory and storing only what is important rather than all the data from a random website. Also, due to this we may achieve faster response time. So, here we can conclude that the proposed system may be more better than the previous systems

Switches are multilayer and can sit on the data link layer (layer 2) when processing and forwarding data, also on the network layer (layer 3) by using IP addresses when forwarding

Google’s search engine allows users to input and submit data online. In return, the user would receive relevant search results. Behind the scenes upon the submission, web crawlers scan through billions of pages and link keywords from a user’s data to the publish data on the web. Their PageRank technology ranks these pages by the number and popularity of other sites that link to the page. This provides the user with accurate and popular results. Google search engines generated high revenues between advertising on its websites and selling its technology to other sites.

Sixth grade language arts class brought a painful experience that I never knew was coming. My class went outside to work on an independent reading project, and all of a sudden, I started to get extremely itchy. My skin, throat and eyes started tingling and throbbing. I rubbed my eyes without thinking twice about what was going on, I'd never experienced anything like this before. I ended up itching my eyes so much that they started to get red, dry and inflamed. I could have sworn they were at least two times the size that they normally were, if not bigger. As I stumbled down to the nurse’s office, barely being able to see, I wondered ‘what's happening to me? What caused this?’

When searching for a vehicle, you have a lot of options. However, thanks to technology and the World Wide Web, many people are choosing to skip the local dealerships and “for sale” adds and looking online to find their next new car or truck.

Below, to help you on your search, you will find what most people consider to be the best

For the last millennium, adventurous souls have been accessing new and unfamiliar frontiers in search of adventure and a taste of the exotic. The last decade ushered in with it an appeal to the more intrepid members of this small group of people: The Internet. Access to this particular medium has hit an all-time high in the 1990's, and every tekkie has his own celebration of self occupying space on it. However, not all of the sites on the Internet are shameless celebrations of self. Some of these pages can be found to have their roots in the archaic designs of the past; some are the logical progression for a technological innovation such as the internet.

The search engine industry is commonly known to have started in 1990 with the release of Archie, a tool used to search the (pre-web) Internet, allowing people to find specific files (Buganza, T., Valle, E.D.

Focused crawlers “seek, acquire, index, and maintain pages on a specific set of topics that represent a narrow segment of the web” (Chakrabarti et al. 1999). The need to collect high-quality, domain-specific content results are important characteristics for such crawlers. Some of these characteristics are specific to focused and/or hidden web crawling while others are relevant to all types of spiders. Some of the important considerations for hidden web spiders include accessibility, collection type and content richness, URL ordering features and techniques, and collection update procedures.
