Ranking Algorithms: Application for Patent Citation Network
in: Information Quality in Information Fusion and Decision Making
How do technologies evolve in time? One way of answering this is by studying the US patent citation network. We begin this exploration by looking at macroscopic temporal behavior of classes of patents. Next, we quantify the influence of a patent by examining two major methods of ranking of nodes in networks: the celebrated “PageRank” and one of its extensions, reinforcement learning. A short history and a detailed explanation of the algorithms are given. We also discuss the influence of the damping factor when using PageRank on the patent network specifically in the context of rank reversal. These algorithms can be used to give more insight into the dynamics of the patent citation network. Finally, we provide a case study which combines the use of clustering algorithms with ranking algorithms to show the emergence of the opioid crisis. There is a great deal of data contained within the patent citation network. Our work enhances the usefulness of this data, which represents one of the important information quality characteristics. We do this by focusing on the structure and dynamics of the patent network, which allows us to determine the importance of individual patents without using any information about the patent except the citations to and from the patent.
…of the MBA market at a particular moment. They reflect the prevailing conditions such as salaries, jobs available and the situation at a school at the time the survey was carried out. Results of rankings can be volatile, so they should be treated with caution. The various media rankings of MBA programmes all employ a different methodology. None is definitive, so our advice to prospective students is to understand the ethos behind each one before deciding whether what it is measuring is important for you.

Hungary is 87th in the 2019 World Press Freedom Index compiled by the international organization Reporters Without Borders (RSF), a far fall from last year’s ranking.
Hungary Slips 14 Places in RSF World Press Freedom Index
In recent years, Hungary’s position has fallen significantly. In 2011, it was in 44th place, but the next year, it slipped 16 spots. According to RSF, this happened because “the initiation of controversial media laws” led to “self-censorship becoming a wide-spread practice in newsrooms.” The World Press Freedom Index of Hungary has been falling ever since it received a ranking of 71 in 2016. Countries are scored from 0 to 100, with 0 being the best and 100 the worst. According to the 2019 RSF report, with a score of 30.44, press freedom in Hungary is currently at a ‘problematic’ level.
In an article in the New York Times with the title You underestimate yourself (the electronic version has a more eye-catching title: You Are Not as Good at Kissing as You Think. But You Are Better at Dancing.
Could you read the paper, and make comments on it? Here are some items from the paper:
Do you think you are an above-average driver, as most people do? How do you compare with others as a parent? Are you better than most at dancing? Where do you rank in your capability to save humanity?
Netflix Ranked as No. 1 Fastest-Growing U.S. Brand in 2019
Netflix — whose name has practically achieved verb status — was the fastest-growing brand from 2018-19 among American companies, according to a new study by Brand Finance, a global brand-valuation consulting firm.
The streamer’s estimated brand value more than doubled over the past year, growing 105%, to $21.2 billion, per the study. Brand Finance calculates values of brands using a “royalty relief” methodology, which involves estimating the likely future revenue that are attributable to a brand by calculating a royalty rate that would be charged for its use.
“Netflix delivers high-quality and varied programming to anyone with internet access and a credit card,” said Alex Haigh, Brand Finance’s valuation director. “The platform has embarked on a disruptive approach to media services and now has incumbents in the market looking over their shoulder.”
It would be so great to see the algorithm, which “estimating the likely future revenue”.
