data.cityofchicago.org Chicago’s open data portal provides almost 600 datasets that are updated on a daily basis, ranging from crimes to the quality of water on beaches. 

data.cityofchicago.org/view/caas-knxs Chicago has released more data, including important items such as red light and speed camera violations, problem landlords, and public chauffeurs. 

OPEN DATA PROVIDES A MEANS TO CREATE AN ECOSYSTEM AROUND DATA, WHICH INCLUDES MULTIPLE STAKEHOLDERS AND INITIATIVES THAT EXTEND BEYOND TRANSPARENCY.

“Open data initiatives are an increasingly popular component of governance. At the national level, Chicago’s open data initiative has been held up as a model for cities that are seeking to start their own open data programs.” - National League of Cities, p. 22 

We released our automation framework as an open-source project that can be downloaded to quickly deploy automated updates. It can be freely used by other governments and improvements can be submitted. ETL Utility Kit github.com/Chicago/open-data-etl-utility-kit 

Chicago has a large, vibrant, productive, civic community. This is led by Chicago residents interested in technology and society. Smart Chicago Collaborative and non-profits provide assistance and city officials regularly engage in meetups and other activities. This group has produced several helpful apps. Community 

THE OPEN DATA PORTAL IS NOT SUFFICIENT FOR THE COMMUNITY, BUT SERVES AS THE TOWN SQUARE FOR A COMMUNITY, PROVIDING A COMMON TOPIC OF CONVERSATION FOR EVERYONE. 

LOS DATOS ABIERTOS PORTAL NO ES SUFICIENTE PARA LA COMUNIDAD, PERO SIRVE COMO LA PLAZA DEL PUEBLO PARA UNA COMUNIDAD, PROPORCIONANDO UN TEMA COMÚN DE CONVERSACIÓN PARA TODOS.

The City of Chicago partnered with developers to create LargeLots, a website using #opendata to help residents apply to the City of Chicago $1 lot program designed to encourage investment in struggling neighborhoods. largelots.org 

Chicago Flu Shots was developed to easily find flu-shot locations across Chicago during the fall and winter months. This provides an easy-to-use central website built upon open data by a volunteer. chicagoflushots.org 

This site shows the work completed by city crews and is also based on the data portal. It provides summary statistics of potholes filled, graffiti removal, and other work completed by city council ward. chicagoworksforyou 

OPEN DATA & INTERNET OF THINGS University of Chicago has partnered with multiple institutions to build a mesh network of small sensors, dubbed the Array of Things, that will frequently post data for public consumption. arrayofthings.github.io 

Array of Things The Array of Things will provide hyper- local, temporal data on using a variety of sensors: §Sensors measuring sound and vibration §Low-resolution infrared cameras measuring sidewalk temperature §Climate and environmental data, such as air-quality and temperature

Sometimes, the terms & conditions were onerous for companies to use data. Likewise, people wanted to sometimes correct our data. Data posted on GitHub can be edited by others and comes with a business-friendly MIT license. Open-source data github.com/Chicago/osd-street-center-line 

The open-source approach also lets users submit corrections for data. Like the example above, a mistake was found on the data compared to actuality. 

Open-source data (and the MIT license) allowed openstreetmaps.org to import all of the building footprints in the city, giving the shape of the city to its users. 

OPEN DATA, IN ADDITION TO OPEN SOURCE LICENSING, PROVIDES A PRACTICAL AND LEGAL FRAMEWORK TO SHARE AND INTERACT WITH THE COMMUNITY. 

DATOS ABIERTOS, ADEMÁS DE ABRIR LICENCIAS FUENTE, PROPORCIONA UN MARCO PRÁCTICA Y LEGAL PARA COMPARTIR Y INTERACTUAR CON LA COMUNIDAD. 

The City of Chicago releases a number of open source projects which can be adopted by other cities or modified by outside developers. This allows a greater community to improve city projects. Open Source Projects github.com/Chicago/RSocrata 

A non-profit which has three primary areas of focus under which we organize all of our work: Access to the Internet & technology, Skills to use technology once you've got access, and Data, which we construe as something meaningful to look at once you have access and skills. 

Smart Chicago’s Civic User Testing group provides incentives and is tailored to encourage regular residents to provide feedback on applications, ensuring they reach beyond a technical audiences. Civic User Testing cutgroup.com 

Smart Chicago Collaborative provides developer resources and limited free hosting of web apps created by civic developers. 

Hackathons Frequently hosted by multiple groups, helps establish networking amongst civic developers. However, these events rarely lead to “Learnathons” Weekend events dedicated to providing free workshops on introductory data analysis and advanced analysis.

Incorporating a data-driven practice is contingent on leadership, practice, and technology. Most cities have the technology framework in place, it just needs to be added. REPORTS DATABASES PORTAL ANALYTICS

#ENGAGEMENT The City of Chicago teamed-up with the Civic Consulting Alliance and Allstate Insurance Company’s data science team to help develop the predictive model. Data from the open data portal was used to develop the model. While other data were considered, almost all of the useful data was publicly available. 

data.cityofchicago.org/view/2bnm-jnvb Chicago leveraged the open data portal to share data with external researchers, leveraging the city’s premiere method of sharing data and saving time on data- sharing agreements. #OPENDATA 

Restaurants with previous critical violations Three-day average high temperature CDPH risk level Location of restaurant Nearby garbage and sanitation complaints Type of facility Nearby burglaries Whether the establishment has a tobacco or has an incidental alcohol consumption license. Length of time since last inspection. Length of time the restaurant has been inspecting. The model predicts the likelihood of a food establishment having a critical violation, a violation most likely to lead to food borne illnesses. Over a dozen data sources were used to help define the model. Ultimately, ten different variables proved to be useful predictors of critical violations. Significant Predictors: 

Data-driven Status quo 0% 10% 20% 30% 40% 50% 60% 70% The research revealed an opportunity to find deliver results faster. Within the first half of work, 69% of critical violations would have been found by inspectors using a data-driven approach. During the same period, only 55% of violations were found using the status quo method. Critical violations 

After comparing a data-driven approach versus the current methods, the rate of finding violations was accelerated by an average of 7.4 days in the 60 day pilot. That means more violations would be found sooner by CDPH’s inspectors. 7 days IMPROVEMENT The food inspection model is able to deliver results faster. 

OPTIMIZING FOOD INSPECTIONS Impact Discovering critical violations sooner rather than later reduces the risk of patrons becoming ill, which helps reduce medical expenses, lost time at work, and even a limited number of fatalities.

The project was released using an academic- quality technical paper instructing others on the variables and statistical methodology used in the project. In addition to source code, the paper will help researchers adopt this approach. Technical Documentation 

The technical paper was written as a highly- reproducible “knitr” document, allowing other researchers to understand how summary numbers were calculated. Each statement in the project can be traced to an original source. Reproducible Research 

The data science team has built a website which lets CDPH prioritize inspections based on projected risk. 

http://github.com/Chicago The analytical model will be released as an open source project on GitHub, allowing other cities to study or even adopt the model in their respective cities. No other city has released their analytic models before this release. #OPENSOURCE 

CHICAGO ECOSYSTEM Chicago’s ecosystem is driven by leveraging open data and open source solutions for easier sharing amongst a network of partners.
