5 Ways Big Data can Help us

 by Lorena Salvado, San Marin High School 

Data storage centers


Big Data, or large data sets are used to train machines and programs (using specific algorithms) to identify and solve problems in our world. Many machine learning algorithms focus on identifying images and recognizing early symptoms of many illnesses, helping patients and doctors alike. Many other algorithms work around predicting our voting and economic futures- each equally important. All of these algorithms are fueled by large data sets, or Big Data, which help train the machine ( or AI) and help it in making more accurate predictions and decisions. 

Many researchers, such as Abby Smith who came to Marin Science Seminar and talked about the benefits of Big Data in her talk :“Data Science for Social Good”, use these algorithms to predict and help marginalized communities. These data collections and datasets help many other organizations in determining help to deliver as well as keeping track of the issues within these communities. 

So, given that there are many opportunities to help using Big Data, here are 5 different and positive ways Big Data is being used to help those who need it. 


1. Tracking and Helping the Homelessness Crisis

One of the main projects Smith worked on, was a predictive and preventative program for individuals that were at close future risk of homelessness in Allegheny County. Her work involved taking data from numerous individuals as well as taking previous homelessness data and patterns and applying it to the current situations. From these programs she can understand who is at a higher risk of near homelessness, and from there the Allegheny County Department of Human Services could intervene and further help these people. This was a very impactful project as it helped many people that were at risk of homelessness. 

2. Local data for Local people 

The Native BioData Consortium (NBDC) is a database run by Native Americnas focused on gathering information about Native Americans. This big data ranges from public healthy COVID-19 surveillance and tracking to the study and documentation of chronic diseases and effects of medicine. This research and data helps foster trust within these communities as well as incorporate more aspects of their lives into science (by incorporating biological, ecological, sociological factors into the data alongside the data itself). It is also used to encourage and teach future Native American scientists and improve their tribes and communities. 

3. Language Preservation and Research 

Language preservation has become a big issue in the recent decades. As predicted by UNESCO, 90% of the world’s languages could disappear within the next 80 years. This means that many small indigenous communities will lose their languages, due to assimilation or benign overtaken in importance and significance by outside cultures and languages. Languages are a very important part of culture, with many aspects of the culture being carried by the spoken or written language. To preserve these languages many have launched large Data Science for Good projects, such as Google’s Wallaroo project. These projects collect large data about endangered languages, their syntax, their phonetic sounds, and their cultural importance. Documenting these endangered languages helps us preserve our cultures and use machine learning algorithms to teach it back to future generations, or simply to understand the language patterns better. Another example of language preservation can be seen in the work done for extinct languages. For example, many Native American languages were lost due to colonization and years of forced assimilation. Many of these languages did not have written forms for us to historically trace back and find. Many language based algorithms are using the little oral data that there is on these languages to predict and “fill in” ( phonetically, grammatically ect) what these languages might have sounded like. This helps many historians and Native communities as they have better chances at recovering their languages and cultures. 

4. Track and prevent Avian Influenza Risk 

During the 2020/2021 Avian influenza outbreak, a team in Korea decided to make a large database containing cases of avian influenza as well as its early stages. This data was later used in many algorithms across the country to help identify and track cases of avian influenza, which helped mitigate the infections and the effects of the illness. Today, with a widespread outbreak of avian influenza going around - with cases even spreading outside of the avian world ( such as cattle and even humans now ! ) large data and algorithms like these are needed. By having a lot of information on the patterns and spread of illnesses, we can better protect our own communities and lessen their spread . 

5. Help Businesses target their consumers better

This is by far one of the most widespread uses of Big Data in our current, modern world. Many businesses ranging from social media platforms, to small business, to large companies all seeking to advertise and adapt to their consumer base  use some sort of data collection systems to keep track of their consumericus. Many businesses have a certain demographic of people in mind to sell their products to ( ex: A business selling paints will want to market their products to other painters or artists looking for paint ) and collecting big data about individual users on platforms or internet browsing helps these businesses target their advertisements in a more accurate way. 


From preventing and tracking homelessness factors, to helping businesses run smoothly and make more profit, to predicting and keeping track of global diseases and preserving and predicting historical and lesser spoken languages, big data and algorithms play a huge role in our world. More and more data is produced every day, and every machine learning algorithm becomes more accurate and more efficient than the last one. These crucial algorithms can help not only our world, in the domains of business, finance, and homelessness, but also the world that we live in, tracking avian flu cases, and predicting natural disasters or helping spaceflights run smoother. And of course, these are just some of the ways that large data sets can be used to help people and improve algorithms. A few more examples can be seen in depth in Abby Smith’s talk at Marin Science Seminar, which can be seen here : "Data Science for Social Good"

Interview with Art Wallace, MD PhD on Big Data and Medical Innovation


By Angel Zhou, Branson School


Mobile technologies, sensors, genome sequencing, and advances in analytic software now make it possible to capture vast amounts of information that could transform medicine. The question is: can Big Data make health care better?

In the upcoming Marin Science Seminar, "Big Data and Medical Innovation," Dr. Art Wallace, Chief of Anesthesia Service at the San Francisco VA Medical Center and a Professor of Anesthesiology and Perioperative Care at UCSF Medical Center, will discuss applications of Big Data in medicine and how Big Data has changed epidemiology, quality improvement, and drug discovery. Read the following interview to learn more about Dr. 

Wallace’s thoughts on Big Data and its impact on medical innovation.

Art Wallace, MD PhD

What is Big Data and what is its significance to medicine?  What makes Big Data different from other data that people work with in the healthcare industry?

Big Data is data that is acquired for other purposes that can be analyzed to understand processes, people, and systems. Big Data includes many things: cell phone records, super market purchase card records, credit card records, medical records, internet search terms, medication usage, hospital admissions, social security records, etc. This data can be used for epidemiology to identify associations between factors and outcomes.

Big Data gives additional power to identify factors associated with rare outcomes. I can now easily do a study in 1 million people using data collected for administrative purposes. Doing a study in 1 million patients used to be enormously expensive, now it just requires computer programming and epidemiologic analysis. Before Big Data, the cost of collecting data was prohibitive, so many studies could not be done. With Big Data, there is little to no cost of collecting the data, making the analysis the entire cost for large studies. The profoundly lower costs with Big Data techniques make studies that were previously impossible, possible at minimal cost.

How does Big Data impact professionals in the medical field? Can Big Data be used to improve healthcare?

We have identified factors associated with adverse outcomes, identified medication practices that are associated with increased mortality, identified medications that can reduce morbidity and mortality, and we have identified possible therapies for diseases that have no current therapy. We can reduce morbidity, mortality, cost, and assist in the development of new therapies.
  
Big Data can be used to reduce morbidity, mortality, cost, and improve efficiency. Big Data can be used to ask questions that are morally, politically, technically, socially, ethically, or legally impossible to answer with randomized trials. Big Data is being used to improve quality of life while lowering costs.

Describe how Big Data is reshaping the drug industry?

Big Data can be used to identify medications that reduce or increase risks. Post marketing testing can identify medications that have significant associated morbidity and mortality. For example, we identified a drug that increased mortality risk 5 fold (increased from 3 to 15% with drug use). This use of Big Data led to a medication being taken off the market. It had been used in Europe for 30 years, in the U.S. for 10 years, and it increased the risk of death from 3 to 15%. Big Data was used to identify a very serious risk to patients and led to the medication being taken off the market.

How will Big Data accelerate innovation in medicine?

Big Data will be used to identify new uses of medications. It will identify risk factors for morbidity and mortality. It will lead to further randomized trials.

What are the benefits and dangers of providing Big Data online as the "ever expanding cloud of information" becomes more accessible?

It is easy to identify people from their digital detritus. It is easy to identify very personal things about people from their data trails. Factors such as financial status, interests, sexual orientation, political beliefs, religious beliefs, health status, pre-existing medical conditions, drug and alcohol use, pregnancy status, and proclivities can all be assessed via Big Data. Big Data can be used to manipulate, track, and market to people. At the same time, Big Data can identify very serious risks to patients’ health. Scientific method is an approach; Big Data is a tool. Both can be used for good or bad purposes. Big Data is simply a new and extremely powerful scientific tool.
