Making Good Use of Data at
Hand: Open Source Tools

Overview
• Open Data concept – Data is produced for
various purposes but can be used to derive
novel insights; i.e. “Business Intelligence (BI)”
• Open Source tools exist for making good use
of existing data sets
– ETL (“Extract, Transform, Load”) + Analytics
• Knime and the R language are two of the most
powerful resources for leveraging data

Open Data
• Open Data concept – governments collect,
through existing management systems, enormous
quantities of data that can be leveraged in
alternative and novel ways to find solutions.
• The goal is often to leverage the broader
community to develop solutions that
governments may not have previously conceived.
• Open Data and Business Intelligence should be
used by internal consumers as well.

Doing Data the Old Way
• Data is locked inside systems :-(
– Software systems are designed to wrap a Graphical
User Interface (GUI) around data.
– The GUI functionality, historically, has to be
programmed to produce reports, views, and analysis.
• The GUI is driven by the sole purpose of the
software. But the data has many purposes…

Open Data – Way Forward
• Making data talk across platforms: AS400, SQL,
XML, Excel, PDF’s, Text Files, Image Files (.png,
.jpeg, etc.), Shape Files (ESRI), email archives,
web-scraping, API’s from social media, etc.
• Connecting data across multiple platforms
• Using data for novel insight
• Tools now exist for importing, cleaning,
standardizing, and analyzing data using complex
algorithms built into accessible packages

Open Data
• These systems are known as “Data Agnostic:”
Database Agnostic - Database-agnostic is a term
describing the capacity of software to function with any
vendor’s database management system (DBMS). In
information technology (IT), agnostic refers to the ability of
something – such as software or hardware – to work with
various systems, rather than being customized for a single
system.

Data Science
• What is the breadth of the tool base?
– Reading in data from various resources
– Transforming data to merge various resources, translate
data into a usable format or to add new data elements
– Analyzing data from basic logical and statistical
functions to higher level machine learning tools and
algorithms
“Machine learning, a branch of artificial intelligence, concerns the
construction and study of systems that can learn from data.”

Data Science
• What is the output?
– “Business Intelligence” or actionable information
that drives business decisions through insight
– Creating new insights from existing data
– Visualizations - representation of that BI in ways to
make it consumable to a non-specialist audience
“According to Friedman (2008) the "main goal of data visualization is
to communicate information clearly and effectively through
graphical means.”

• Knime is a GUI-based data agnostic tool for ETL,
analytics, and visualization.
• Knime is an open source platform for the desktop
with commercial enterprise server layers
including collaboration tools and web-services
(web-portal).
• Knime supports other analytics languages,
including the R language for statistical computing

• The advantages of Knime:
– Rapid development environment
– Very powerful processing handling large datasets
on commodity hardware
• Allows for 100% data samples up to millions of
elements row-wise
– Workflows can be saved, shared, and duplicated
– nodes are stepwise allowing for quick revisions
– nodes provide access to complex algorithms

Knime Nodes
• Nodes are the workers inside a
workflow
• Every node serves at least one
function
• Nodes can also be built as MetaNodes, which are a collection of
nodes performing common
functions
• A collection of nodes is called a
“workflow”
• You can develop nodes with Java
and the node development
support

Knime Nodes
• For example, the file reader node
is an intelligent file reader that
can determine the type of file
• However, it also allows for the
end user to adjust parameters

Knime Nodes
• The Column Filter node
allows users to filter
columns from a table
(conveniently named…)

Knime Integrates with R
• R integration is key to expanding
the data analysis and visualization
capabilities of Knime
• R supports data ingestion of
complex files (including ESRI)
• R supports complex data
manipulation and statistical
analysis
• R supports a wide variety of highly
customizable visualizations
So, what is R, exactly?

R Project for Statistical
Computing

• R is an open source scripting language which can be run
inside Knime, but also within a command line environment
independently
• Several GUI interfaces for R exist such as R Studio, a group
that provides software for using R as well as training and
extension packages (www.rstudio.com)
• Community contributions make up the bulk of R packages,
which now total more than 4,700

• The R base package (standard software) provides methods
for reading data, ETL, analysis and visualizations
• The community provided packages take this base and build
on it depending on the interest of the producer
• Packages stretch across all imaginable data uses, including
advanced statistical analyses, machine learning and data
mining, and advanced graphical visualizations (including
sophisticated mapping)

Popular R Packages
A (very) brief overview of popular packages:
• Plyr – for advanced data manipulation
• Maps – for mapping datasets onto georeferenced outputs
• GGPlot2 – for advanced data visualizations
• Rcurl – for reading data from webpages and repositories
• TextMining – for text mining applications
• SNA – for social network analysis

Knime + R + TPP
Case examples for working with TPP:
• Look at distribution of TPP accounts across a county, state, or
region
• Map entities or create a heatmap (choropleth) of the
distribution of personal property values
• Compare personal property reporting across schedules across
industry sectors (m&e across manufacturing types)
• Compare like-kind entity reporting (franchises, big-box) for
consistency in values
• Compare personal property accounts with other data
resources (real property accounts, permits, etc.)

Brief Demonstration
Data:
Florida
67 Counties
More than 1.24 million personal property accounts
Goals:
1. Group all data by industry to illustrate the taxable value and
exempted value by type
2. Subset the data to include only a particular industry
3. Map the state-wide exempt value in a choropleth
