The Practice of Data Science

11 The Practice of Data Science Josh Wills, Data writing on The Practice of Data Science said:The Practice of Data Science – Key trait of all data scientists. Understanding “that the heavy lifting of [data] cleanup and preparation isn’t something that gets in the way of solving the problem: it is the problem.” (DJ Patil)DJ Patil – Inverse problems. Not every data scientist is a statistician, but all data scientists are interested in extracting information about complex systems from observed data, and so we can say that data science is related to the study of inverse problems. Real-world inverse problems are often ill-posed or ill- conditioned, which means that scientists need substantive expertise in the field in order to apply reasonable regularization conditions in order to solve the problem.inverse problemsill-posedill- conditionedsubstantive expertise – Data sets that have a rich set of relationships between observations. We might think of this as a kind of Metcalfe’s Law for data sets, where the value of a data set increases nonlinearly with each additional observation. For example, a single web page doesn’t have very much value, but 128 billion web pages can be used to build a search engine.Metcalfe’s Law – Open-source software tools with an emphasis on data visualization. One indicator that a research area is full of data scientists is an active community of open source developers. 11

12 Current US Government Semantic Web Strategy Data.gov Advocates RDFa 1.1 Lite for Semantic Web Strategy. – See Comment From Owen Ambur on Next Slide. I believe there is a better way to handle this that I showed the W3C eGov Special Interest Group on January 21st and have recommended for the reintroduction of the Data Act to the 113 th Congress. – Create a Semantic Index of Strong Relationships (SR) in RDF Format in a Spreadsheet. See next slide for example (spreadsheet and words) – Integrate That With Other Spreadsheets and Relational Databases in An Interoperability Interface (e.g. Dashboard) That Can Searched. Essentially: – Computer Scientists Use RD2RDF (James Hendler) – Data Scientists Use SR2Excel2RDF (Brand Niemann) 12

13 Comment From Owen Ambur OMB's official guidance to agencies on implementation of section 10 of the GPRA Modernization Act (GPRAMA) says they may use XML, JSON, spreadsheets or CSVs in order to meet the requirement to publish their strategic and performance plans and reports in machine-readable format... but not PDF or HTML -- at least not without "enhanced structural elements".[1] I couldn't help but chuckle at how [1] is a PDF. I get your point however, which I think reinforces mine, that there is no US federal policy that prefers RDFa 1.1 over HTML Microdata for publishing metadata in HTML. – [1] RDFa Lite 1.1, W3C Recommendation, June 7, 2012, Manu Sporny, editor, see Source: Owen Ambur, December 18, 2012, W3C eGov Mailing List. 13

14 International Linked Open Data Strategy: Linked Open Data Cloud Data 14 My Question: Is it easy to add columns for who links to who? Answer: Not in a single table. SPARQL can't do cross- tabulation (Richard Cyganiak).

15 International Linked Open Data: Comments to David Wood The Linked Open Data Cloud is not actually “linked data”. – RDF at Data.gov is not linked data. The analytical and statistical communities view Data.gov and Linked Open Data as “IT projects”. – Former Census Bureau Director Robert Groves. Conventional tools can do linked data and data integration. – Spotfire Information Designer, Informatica, Information Builders, etc. 15

17 Our Semantic Web Strategy for Big Data: Previous Presentations 17 MITRE: October 2, 2012 GSA: November 29, 2012

18 Our Semantic Web Strategy for Data: Simple Explanation One Table: – Two Columns Example: Column 1: Section and Column 2: URL Note: A Column 3: Description could be in the URL Example: See Next Slide – Three Columns: Example: Column 1: Subject, Column 2: Object, and Column 3: Predicate Note: This is the Semantic Web’s Linked Open Data Cloud as Linked Open Data for Network Analytics! Example: See Semantic MedlineSemantic Medline – Four Columns: Examples: Column 1: Subject, Column 2: Attribute, Column 3: From, and Column 4: To, or Column 1: City, Column 2: Country, Column 3: Longitude, and Column 4: Latitude Note: This is the format for Spotfire’s Network Analytics Module developed for the CIA Example: See Semantic MedlineSemantic Medline 18

21 My 5-Step Method So what I like to do to illustrate (data science) and explain (data journalism) is the following (like a recipe): – Put the Best Content into a Knowledge Base (e.g. MindTouch*) NASA Big Data – Put the Knowledge Base into a Spreadsheet (Excel*) Linked Data to Subparts of the Knowledge Base – Put the Spreadsheet into a Dashboard (Spotfire*) Data Integration and Interoperability Interface – Put the Dashboard into a Semantic Model (Excel*) Data Dictionaries and Models – Put the Semantic Model into Dynamic Case Management (Be Informed*) Structured Process for Updating Data in the Dashboard 21 * Examples of tools used.

22 To Get to 5-Stars With Open Data StarDefinitionExample / Tool* Make your stuff available on the Web (whatever format) under an open license This StoryThis Story / MindTouch Make it available as structured data (e.g., Excel instead of image scan of a table) SpreadsheetSpreadsheet / Excel Use non-proprietary formats (e.g., CSV instead of Excel) TableTable / MindTouch and Spotfire Use URIs to identify things, so that people can point at your stuff Table of ContentsTable of Contents / MindTouch and Spotfire Link your data to other data to provide context TableTable / MindTouch and Spotfire 22 * Examples of tools used.

24 Data Federation in Spotfire: In-Memory and In-Database Data In-Memory Data – When you are working with in-memory data tables (text files, Excel files, information links, etc.) you have access to all the functionality of Spotfire. You have the opportunity to use all columns as filters and perform any number of calculations. You can also use any of the tools within Spotfire to cluster data, calculate new columns, bin columns, make predictions etc. See Working With Large Data Volumes for some tips on how to improve the performance of an analysis with lots of data.Working With Large Data Volumes In-Database Data – When a connection to an external source is set up, all calculations are done using the external system and not with the Spotfire data engine. This will allow you to work with data volumes too large to fit into primary memory and take advantage of the power of the external system. When working with external data connections, you access only the current selection of data and all aggregations and calculations are made in-database (in-db). 24

25 Data Federation in Spotfire: Database Connections, Information Links, & Analytics Library 25 A database connection dialog is used to set up a connection to say a Teradata database, where you can analyze data from the database without bringing it into your analysis. An information link is a structured request for data which can be sent to the database. These specifications include one or more columns, and may include one or more filters. – Stated in plain English, an information link could be: "Fetch the Name, Address and Phone_number for employees that pass the filter High_Income." – Information links can also be used to limit what data to open in an analysis in a number of different ways. The library provides publishing capabilities for all of your analysis materials, so you can share data with your colleagues. The library can be used directly from Spotfire by anyone who has at least read privileges.

26 Data Federation in Spotfire: Data Panel The Data panel is used to get an overview of the columns in all data tables, in-memory as well as in-database (in- db). When working with in-database data the Data panel is the starting point for configuring both visualizations and the filters panel, since no filters are created automatically for external data. 26 https://silverspotfire.tibco.com/us/library#/users/bniemann/Public?NASABigData-Spotfire

27 Data Federation in Spotfire: Information Designer The Information Designer is a tool for setting up data sources and creating and opening information links. An information link is a database query specifying the columns to be loaded and any filters needed to narrow down the data table prior to creating visualizations in Spotfire. In Information Designer, information links are created from building blocks such as columns and filters using joins, calculations and aggregations. 27
