There are different methods of searching the web.
Search engine | method |
---|---|
Primarily uses page rank to determine relevance | |
ask.com | Whereas Google’s PageRank ranks its
search results by popularity, Ask has something it calls “ExpertRank”. Essentially this is an automated search algorithm (like Google has), but on top of that results are ordered using topic communities and the editorial functions that create ‘Smart Answers’. While the ExpertRank formula is a secret sauce that Ask.com won’t divulge, they do say that the top results in searches are determined by expertise – and not popularity. As it states on their help pages: “Identifying topics (also known as “clusters”), the experts on those topics, and the popularity of millions of pages amongst those experts — at the exact moment your search query is conducted — requires many additional calculations that other search engines do not perform.”[2] |
wolfram alpha | Wolfram Alpha (also styled WolframAlpha and Wolfram Alpha) is a computational knowledge engine[5] or answer engine developed by Wolfram Alpha LLC, a subsidiary of Wolfram Research. It is an online service that answers factual queries directly by computing the answer from externally sourced "curated data", rather than providing a list of documents or web pages that might contain the answer as a search engine might.[3] |
Internet archive | The Internet Archive is a San Francisco–based nonprofit digital library with the stated mission of "universal access to all knowledge." It provides free public access to collections of digitized materials, including websites, software applications/games, music, movies/videos, moving images, and nearly three million public-domain books. As of October 2016, its collection topped 15 petabytes. In addition to its archiving function, the Archive is an activist organization, advocating for a free and open Internet.[4] |
Do you understand this?[edit]
Can YouTube be classed as a search engine? Google’s Panda puts the focus on quality. Cloud Kite (Open Drive) for searching the cloud. Multimedia search engines (visual / audio).
