Summary: We used API (Application Programming Interface) as the source to extract data from the USGS database in order to analyze the last 50 years and estimate the frequency of earthquakes in Southeast Asia. With the help of Python, the extracted data was exported into CSV file for categorizing different parameters such as by country, magnitude and year.
Application programming interface (API) is commonly used to extract data from a remote website server. In layman term, API is used to retrieve data or information from another program. There are several websites such as Facebook, the USGS, Twitter, Reddit, which offer web-based API helping get information or data.
In order to retrieve data, we will send requests to the host web server where you want to extract the data and tweak parameters like URL in the module to connect to the server. Different websites have different requests format and can easily be accessed through the host’s website.
In our module, we will be extracting the data of earthquakes that hit Southeast Asia in the last 50 years from the web server of USGS using API.
One of the most frequent natural disasters on planet earth is earthquake. The sharp unleash of energy from Earth’s lithosphere generates seismic waves which lead to sudden shaking of the surface of the Earth. This natural disaster has led to the death of thousands of millions of people all around the world.
The strength of earthquakes is measured through Richter magnitude scale or just magnitude. The magnitude is the scale which ranges from 1-10.
The most highly sensitive region in the world prone to the earthquakes are Southeast Asian countries. To find the trend in the region, we extracted 50 years data from USGS by using API and convert the numbers into CSV file through Python coding for a comprehensive understanding of earthquakes situation in Southeast Asia.
Summary: Unfair and imbalanced news stories always mislead readers, hiding and even distort truths, thus decreasing the credibility of media as well as increasing ‘news victims’. As a qualified news organization, one must get its news as close to the fact as possible. This time we want to take China Daily as an example, to analyze whether its news is fair or not.
We decided to rely on data to quantize the requirement, thus we use python to show the most effective way to figure out the fairness of news.
Background: Difficulty to Reach Absolute Objectivity
According to the Cambridge online dictionary, objectivity means “not influenced by personal opinion or feeling.” For a long time in journalism, objectivity meant writing a story without putting any personal opinion into it.
Over the last several years, many journalists stopped using “objectivity” in favor of the word “fairness.” Complete objectivity, they reasoned, is impossible. Fairness is more possible. Fairness means that you tell a story in ways that are fair to all sides once all the available information is considered.
Telling a story fairly is more difficult than it sounds. Reporters try to put colorful images and descriptions into their stories. For fresh reporters, especially those working in a second language, it can sometimes be difficult to distinguish between colorful description and editorializing. Some words have a feeling or connotation to them that is hard to recognize. Some English words have “loaded” or “double” meanings that are extremely positive or negative. Writers should be aware of the positive or negative meanings of a word and how its use to affect an article. Also, as human beings, we all have feelings and opinions about events and issues around us—-it is sometimes difficult to conceal those feelings, especially if we feel strongly about something. These feelings sometimes come through in our stories in the words we choose.
Therefore, the TextBlob, a module of python, is designed for pointing out humans’ subjectivity in news.
Professor Jordan Peterson has been the center of attention in last few weeks for participating in a number of debates regarding gender wage gap. Unlike the feminists calling for the reduction of discrimination over salary, he believes gender wage gap is an explainable consequence of multiple social factors rather than a problem caused by discrimination. Is he right? After all, why is there gender wage gap? Looking into 3 reports (Why is There a Gender Wage Gap – Our World in Data, Six Key Facts About the Gender Pay Gap – Our World in Data, Gender Pay Gap: the Day Women Start Working For Free – Washington Post) and a published recently with analytics over statistics regarding gender wage gap will give us a thorough understanding of current gender wage gap.

Nathan Ruser, a 20-year-old Australian National University student who is majoring in international security with a keen interest in cartography, discovered a fitness app had revealed the locations of secret military sites in Syria and elsewhere. He posted on Twitter about this, did not expect much response.
But the news ricocheted across the internet. Security experts said the Strave app’s “heat map” could be used by hostile entities glean valuable intelligence. The Pentagon said it was reviewing the situation.
How he found the news?
“Whoever thought that operational security could be wrecked by a Fitbit?” Mr. Ruser, said in an interview with New York Times from Thailand, where he is spending part of the Australian summer break.
When he looked over Syria on Strava’s map — which is based on location data from millions of users, including military personnel, who share their exercise activity — the area “lit up with those U.S. bases,” he said.
Before publicly sharing his findings over the weekend, he discussed them in a private chat group on Twitter, made up of people interested in intelligence and security issues. “I know about two-thirds of what I know about the world from the group chats,” he said.

It is time to break-down the broad concept of “data journalism”. When talking about the combination of data and news, we usually refer to two processes, sometimes conducted in an integral manner. One process is to discover news points from datasets. The datasets can provide a lead for further investigation. The final product does not necessarily reflect the usage of data. It may look the same as normal news products mainly composed of interviews and photos. This is called “data mining” in the science domain. Another process is to present news points using data. There come to all kinds of charts and interactive/ immersive presentations. This is called “data visualisation” in the science domain.
Let’s focus on the “data mining” part in this article. That is to discover news from datasets, or more precisely discover a news lead from datasets. The further development of the entire news story may take much more efforts with a combination of traditional and modern methods. For easier discussion, we treat “news” in the general form: something the audience does not know before reading, a.k.a, something that “appears new”. It could be the status update of a current affair, or it could be the “new knowledge” to the readers (probably be “common knowledge” to experts which we don’t want to waste time debating).
As advocated by the “Road to Jan”: the most profound theory takes the simplest form. As a first step, we try not using programming, or even sophisticated spreadsheet skills. One can readily find some “news” with a bit “nose for news” and be computer literate is good enough. In this article, we will demo a few news points mined by our undergraduate students from Hong Kong government data portal: https://data.gov.hk . It took around 20 minutes in the second class of a data journalism course. We start with a public dataset from the portal, check out the data tables and eyeball if there is anything interesting. The process is so quick that we would like to give it a brand name: Lightning News. One can sharpen his/her news sense and data sense by doing this as daily exercise.

媒體在數字化轉型中，越來越多地用數據可視化作為呈現方式。但許多可視化的作品只是追求形式上的美感，沒有實現數據可視化真正的功能：清晰有效地傳達信息，使讀者更形象地理解數字背後的含義。媒體推出的可視化新聞良莠不齊，水準忽上忽下，卻少有懂行的同行或讀者給予反饋。本週的數據新聞給讀者介紹由Perceptual Edge網站創始人、信息視覺化專家Stephen Few提出的一個標準化衡量規則，評價可視化是否達到了必要的效果。
