Private Search Engines
In lecture, we discussed how search engines like Google come across the Problem of Abundance where there are just too many pages that could contain a key word. As a result, they employ all sorts of algorithms in order to weight each page through authority scores and hub scores. According to my news article, Google […]

Bargaining in Networks in the Airline Industry
The air transport industry is a great example of network exchange theory. The main players in the air transport industry are the airplane manufacturers, the airlines, and travel agents. These players interact with each other and airline customers. One of the key interactions is between the airlines and the airplane manufacturers. In this interaction, the […]
YouTube’s Video Search Algorithm
We discussed in class how search engines like Google utilize page rank algorithms to prioritize certain websites when ranking the pages relevant to a search. Google famously bought the popular video-sharing site YouTube in 2006. As an avid YouTube watcher, I was curious how YouTube determined which videos to rank first. How did they determine […]
Wikipedia as a Network (The Wiki Game)
Wikipedia, a free online encyclopedia, is well-known for the range of topics that it covers. Wikipedia also has the distinct feature of excessive internal linking. That is, one will find that every Wikipedia article inevitably has hyperlinks to other Wikipedia articles, in addition to external links. Visualizing Wikipedia as a network, then, yields an interesting […]
Fake Product Reviews

Certain companies pay people to write fake reviews for their product which results in their company’s product being featured higher in amazon’s search results. Why is this important, and why does Amazon care? The reason for this is because […]
Submodular Functions in Generalized Matching Markets and Game Theory
A set function (a function mapping a set to a value) is said to be submodular if it has the property that the function value increases more and more slowly as more elements are added to the input set. Intuitively, these functions have a diminishing returns property. Recently, there have been much research into this […]
Market Clearing Wage and Efficiency Wage
In class, we learned about market clearing prices for items, such as parking lots, and how these prices result in a perfect matching in the preferred-seller graph. We can also apply this market concept to labour. In this scenario, we can think of labour as the item. The market clearing wage would then be the wage […]
Changes to Google’s Mobile Search in Early 2015
https://www.washingtonpost.com/news/the-switch/wp/2015/04/20/google-is-about-to-dramatically-change-how-search-works-on-your-phone/ In class, we have been discussing the ideas that one needs to implement when designing a search engine. We have gone into depth for one method that this can be done; however, this method is by no means the only way to implement search engines. In fact, Google, often makes small changes to their […]

The article discusses the history of Facebook and their most popular […]
