11. The Practice of Data Science • Josh Wills, Data Scientist @Cloudera, writing on The Practice of Data Sciencesaid: • 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) • 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. • 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. • 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.

12. Current US GovernmentSemantic 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 113th 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)

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 pointhowever, which I think reinforces mine, that there is no US federalpolicy that prefers RDFa 1.1 over HTML Microdata for publishingmetadata in HTML. • [1]RDFa Lite 1.1, W3C Recommendation, June 7, 2012, Manu Sporny, editor, see http://www.w3.org/TR/rdfa-lite/ • Source: Owen Ambur, December 18, 2012, W3C eGov Mailing List.

14. International Linked Open Data Strategy:Linked Open Data Cloud Data 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). http://semanticommunity.info/@api/deki/files/8824/=VIVO.xlsx

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. http://manning.com/dwood/LinkedData_MEAP_ch1.pdf http://semanticommunity.info/AOL_Government/Exploiting_Linked_Data_with_BI_Tools

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 * 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. • 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).

25. Data Federation in Spotfire:Database Connections, Information Links, & Analytics Library • 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. 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. http://semanticommunity.info/Build_DoD_in_the_Cloud/Enterprise_Information_Web_for_Semantic_Interoperability_at_DoD/Spotfire_Data_Federation http://semanticommunity.info/Build_DoD_in_the_Cloud/Enterprise_Information_Web_for_Semantic_Interoperability_at_DoD/Spotfire_Information_Designer
