Sentiment analysis explained in 1 minute

While googling "Sentiment analysis metrics" I came a cross an instructive and useful video series on YouTube called "1 metric, 1 minute" where Dr. Kaye Sweetser from University of Georgia explains diverse social media metrics around 1 minute. Here is the information on her YouTube channel. You find the link below.

Dr. Kaye Sweetser from UGA quickly discusses what to count when it comes to social media. She said raw counts of number of followers is not meaningful and suggests counting engagements instead. This is a part of a social media measurement series for her students called "1 Metric, 1 Minute."

Metrics in the future of education: Revolution of free global digital education

I once asked my university lecturer in mathematics: "don't you think we (students) would better and quicker grasp the complex equations if you were showing and rotating the 3D figure projected on the whiteboard instead of hand-drawing it and really try hard to have us imagine different rotations and perspectives?", my teacher looked at me as if I had just came from a distant planet.

Now what it seems to happen with education (and beyond just math) is so much more than just throwing 3D shapes on the wall using computers. Aaron Saenz at Singularity Hub posts "Yes, The Khan Academy IS the Future of Education":

I am left with little doubt that the Khan Academy represents the future of education. And it’s already here. Sal Khan does a very thorough job of explaining the ways in which the Khan Academy website takes its 2000 videos and expands them into a complete set of lessons, test exercises, and evaluations. If I could just highlight a few moments, however, I would point to the incredibly detailed blow by blow analysis that KA keeps of a student’s progress. Teachers can see the results of each and every problem the student attempted. ... With the Khan Academy, teachers would “intervene only when a student is stuck.” In other words, the KA is supplementing the education paradigm in such a way that teachers are only needed as corrective influences. They’ll be tutors more than lecturers. ... You can track your progress with some wonderful metrics. Teachers (or ‘coaches’) can monitor student progress in groups. Students can earn badges to keep them interested. The list goes on and on and it’s all free.

Aaron further writes:

My secret hope is that by the time I have children, and they are ready for school, they will be among the first generation raised in the new paradigm of digital education.

Aaron, I share your dream.

The new metric centric site "What Metric" is launched

A new metric centric site is launched:

Based on a mass collaboration model, What Metric attempts to serve as a knowledge base and a library of all sorts of metrics. What Metric's primary (and nearly impossible) task is to identify, collect, and organize all types of metrics in diverse fields and applications.

Measuring and tracking body metrics in healthcare and fitness is a popular and growing application so I wanted to kickstart this topic by this app update from Matrix information systems inc. (this is not a product test and review)

Body Metric’s is designed with the Health Care Professional in mind, utilizing standardized CDC datum, known calculations, and reasonable assumptions. This application is not designed for the lay person, but rather assumes a certain base knowledge in how to properly interpret the values.

Features include:
• Percentiles based on CDC datum for infant and youth.
• Gender specific.
• Displays colour coded spinners for percentiles.
• Calculates age in months from birthdate.
• Exact value entry permitted.
• Spinners for fast selection.
• Double tap age and spinners center on 50 percentile.
• Switches datum automatically based on age.
• Detailed synopsis of patient by rotating device to the side.
• Supports both metric and imperial units.
• Support for data entry using both metric and imperial units.
• Complete CDC tables for infant and youth.
• Includes a Help section detailing usage and all formula’s.
• Ideal weights (Robinson & Devine) for adults.
