Chris Nolan's Presentation

Mr Nolan's lecture taught me a great deal about search engines on the internet. I learnt that Google uses a different searching system to find relevant hits to a search term. Google uses a links and reference system to determine relevancy. They look at the amount of links and relevancy of the links that go to the particular sites that relate to the search term. The more highly cited websites get more relvance 'points' and therefore are higher on the list of hits. I was also surprised to learn about Google's advanced search system; you were able to limit the search to a particular website, whether that be a government site (.gov), and educational website (.edu), or a not-for-profit organizational website (.org). Google also has another search engine named Google scholar, which lists peer reviewed journal articles. The lecture gave me many new skills that will help me in my research projects.
