VoCAL, Voice with CityU Apps Lab (CAL), aims to inspire CityU students by showing the inspirational real life example. Through an interactive sharing, students can be inspired and think out of the box and meanwhile speakers can gain feedback and spread positive messages.
With Internet of Things (IOT), technology advancement and big data being more common in our daily life, Data Analytics is a new job area that surfaced in the 21st century.
Being able to get access the powerful internet world at ease, we are exposed to a considerable amount of data at any time and any place. Therefore, the ability to find a pattern, analyze and make a conclusion from a big pile of data is extremely valuable.
Pili Hu, a data scientist at Initium Lab shared his experience in data analytics during the mini-VoCAL sharing on 22nd August 2015. His sharing mainly focussed on the Legco matrix, a project that he worked on to visualize the recent movement and voting situation of Hong Kong legislative council. By looking at the 70 x 70 Legco matrix, he extracted a lot of the hidden information about HK LegCo.
Throughout the sharing, he told the audience about his motive to start this project, the model and methodology he used in analyzing voting data, the process and challenges he faced as well as the findings and result he obtained from this project. Besides the matrix, he and his team also developed a mobile app that is able to read the matrix so that a normal layman could simply understand the meaning behind each cell of the matrix. To let the disabled able to understand the project, they even made a 3D printed version of the matrix. “We’re trying to make this more understandable for the public,” said Pili.
“Our project is an open-sourced project, if you ever think that the conclusion shouldn’t be in this way, you may use our code to remodel the whole thing again. I believe that at last, you will find the same result”, said Andy, one of the project members. “To make information reliable, it is very important to display the methods you used to generate the information to the readers. Being transparent is the best way to prove the reliability of any information.”
The details of the events are recapped as follow:
In Hong Kong legislative council, there are 70 members who can propose or vote for motions. Besides the Legco members, 12 government departments can also propose motions. How do they behave in the legislative council? Who votes for the most “Yes” or “No”? Who is top absent person? Are the pan-democrats camp and pro-establishment camp holding totally different views on all issues? How do members’ political standing evolve over time? Do you know that most motions are voted in one of the last weeks of “a semester”?
