Higher knowledge beats intelligent algorithms, however extra knowledge beats higher knowledge.
— Peter Norvig
I constructed a factor. It was enjoyable, and I believe it introduced (or hopefully will carry) worth. Nevertheless it got here at an expense which I’ve grow to be all too aware of in my trade. It shouldn’t be (and doesn’t must be) the norm that knowledge is tough to entry. I check with this as Knowledge Jail. It’s straightforward to get knowledge in, onerous to get it again out. And lots of circumstances, the proverbial bars of the information jail are clear. You don’t understand it’s onerous to get to till you have to.
Defining ‘Knowledge Jail’
Let me begin by ensuring we’re all clear on what I imply by Knowledge Jail. Basically, Knowledge Jail describes a situation the place knowledge, regardless of being technically out there, is confined inside codecs that hinder quick access, evaluation, and efficient utilization. Frequent culprits embody PDFs and different doc codecs that aren’t designed for seamless knowledge extraction and manipulation.
Some Context into the Drawback I’m Fixing
Seattle Public Faculties (SPS) introduced close to the tip of the 2023/2024 college yr that they have been unable to beat a price range shortfall in extra of $100M/yr and rising by way of time. Quickly after, a program and evaluation have been initiated which aimed to determine and shut as much as 20 of the almost 70 elementary faculties in Seattle.
I’m a mum or dad of one of many youngsters in considered one of these elementary faculties. And like lots of the different dad and mom who have been thrust upon this program with out a lot warning, I felt annoyed on the lack of open & available knowledge, regardless that the district pointed in direction of quite a few PDFs out there by way of their webpage.
Positive, somebody might go and duplicate/paste the information from every of the PDFs, however that’s going to take an amazing period of time.
Positive, somebody might go have a look at prior analyses that are made out there (once more, by way of PDF), however these analyses would possibly solely be tangentially related.
Positive, somebody might request the information by way of CSVs, however these requests are solely supported by 2 part-time people, and the lead time for getting the information is measured in months, not days.
And so I spent a while making an attempt to amass the information that I imagine anybody would wish to come back to an affordable conclusion on which faculties (if any) to shut. Apparent info like Finances, Enrollment and Services knowledge — for the previous 3 years by college.
Fortunately I didn’t have to repeat & paste the information manually. As an alternative, I used Python to scrape the PDFs with the intention to get a dataset which anybody might use to carry out a strong evaluation. It nonetheless took perpetually.
What’s Potential when the Knowledge is Unlocked
Quick ahead a few weeks from after I began pulling the information, and you’ll see the ultimate product. The app I constructed is hosted on Streamlit, which is a super-slick platform that gives all the scaffolding and help to rapidly allow exploration of your knowledge, or present a UI on prime of your code. You get to spend time on fixing the issue as an alternative of getting to fiddle with buttons, HTML and the like.
My exploration started as an examination of the budgets and enrollment themselves, however then rapidly morphed right into a solution to perceive considered one of many impacts from closing faculties — particularly, how do the scholars grow to be redistributed primarily based on present relationships between enrollment boundaries and variety of college students who attend inside or outdoors of them.
So, that grew to become the first use-case for what I created:
As a member of the group, how will a particular situation of college closures influence different surrounding faculties from a capability perspective?
The entire knowledge may be rapidly downloaded by way of the tables under the maps, and customers can rapidly play with and observe their very own situations. Like, “What in the event that they closed my college?”
An unintended A-Ha!
I did make an attention-grabbing statement whereas analyzing this knowledge. This statement was carried out simply after finishing a reasonably easy linear regression. The y-intercept for the regression was round $760k, which represented an estimated baseline value for having a college open. In easier phrases, by closing a college, and redistributing workers and price range {dollars}, the district will most likely see on common $760k in value financial savings per college. Due to this fact closing as much as 20 faculties, sustaining staffing ranges, and redistributing college students, would save slightly over $15M. There’s a giant hole between that and the $100M deficit that the closures intend to deal with. This most likely warrants some extra evaluation — if solely I had entry to higher (or much more) knowledge…
Breaking Out is a Alternative
As I went by way of this train, it grew to become more and more clear that FOIA and Public Information legal guidelines give a possibility (perhaps unintended) to assist break by way of knowledge jails when scrappy scraping expertise can’t be leveraged.
Others have seemingly requested this knowledge previously, sought and obtained mandatory approvals, and been supplied that knowledge. And regardless that that knowledge shared with the requestor is taken into account public, it’s not made accessible to anybody else in a simple manner. Herein lies the issue. Why can’t I simply have a look at and use the information that others have already requested for and been given?
Wrapping Up
So — I constructed a factor. I scraped knowledge from PDFs utilizing a factor. However, I even have a request within the queue with Seattle Public Faculties and Seattle.gov to get entry to any info supplied by way of public requests and FOIAs for public college knowledge during the last 2 years. These responses and the requests are additionally themselves public data.
However, for individuals who don’t have the abilities to put in writing code to scrape this themselves, this knowledge stays simply past arm’s size, locked behind the bars of PDFs, webpages, & photos. It doesn’t must be that manner. And, it shouldn’t be that manner.
There are actually discussions available on formalizing on a constant format for knowledge within the first place. Issues like commonplace desk codecs comparable to Delta Lake look like a really scalable and cheap resolution throughout the board (Thanks Robert Dale Thompson), however even making the information from previous FOIAs and public data requests accessible on present websites comparable to knowledge.seattle.gov look like desk stakes.
Let’s work collectively to unlock the potential of public knowledge. Try my Streamlit app to see how accessible knowledge could make an actual distinction. Be a part of me in advocating for open knowledge by reaching out to your native representatives and backing initiatives that promote transparency. Share your individual experiences and information together with your group to unfold consciousness and drive change. Collectively, we are able to break down these knowledge jails and guarantee info is really accessible to everybody.
Extra to come back, as soon as I get entry to the information.
