RESEARCH IMPROVING DATA GATHERING & Luca Matteis
What is Research?
"In the broadest sense of the word, the definition of
research includes any gathering of data, information and facts for the advancement of knowledge."
"Research is a process of steps used to collect and
analyze information to increase our understanding of a topic or issue"
Data is essential for research
Where do we get data from? Einstein got his data
from his own experiments and from other peoples experiments Information exchange took weeks if not months
Today we have the internet! Information exchange takes milliseconds Works
much better than anything Einstein had
BUT THERE’S STILL ISSUES
DATA IS SCATTERED ALL OVER THE WEB

Information that can be extremely valuable, lives somewhere online and
we don’t know it because we can’t find it
EVEN WITH GOOGLE, IT’S STILL HARD TO FIND WHAT WE
NEED
Scientific data searching is facilitated if there is a central
repository or data bank

When our information is centralized by context, we can more
easily find what we’re looking for
We already have websites that centralize this information
And allow us to find data that Google couldn’t
BUT THERE’S ROOM FOR IMPROVEMENT
How is this data currently being centralized?
Each center sends us their data in the form of
Excel or Access files, through FTP or Email
None
THIS IS AN ENTIRELY MANUAL PROCESS
Is this sustainable?
Is this sustainable? This process needs to be automated
• no human interference • less communication hassles • less
human errors • more accurate data • more data What are the advantages of automating the data exchange process?
How do we automate? Centers no longer have to send
us anything. We get it directly from their website
There’s no secret. Google, hotel sites, flight search engines and
many others do this It is called web scraping
How does it work
We automatically navigate to the centers websites and fetch the
information that we need
We automatically navigate to the centers websites and fetch the
information that we need This is done by little scripts called spiders or web crawlers
What? Spiders?
“A Web crawler (or spider) is a computer program that
browses the World Wide Web in a methodical, automated manner or in an orderly fashion.”
None
This process allows us to reach more centers and gather
more data
For each center to have a website that displays their
information The main requirement Without a website we wouldn’t be able to automate this exchange
