‘Big Data’ Public Databases: An Annotated Bibliography

Big Public Databases

1.     Kin Lane’s Federal Dataset Tool

http://federal-agency-dataset-adoption.publicprivatesector.org/index.html

Many of the following listings refer to US Federal Government datasets. These are some of the biggest public datasets available. Unfortunately, much of this data is messy, published without much regard to its consumption and use.

This project, from Kin Lane, is both an index of a huge number of Federal Government datasets, and a way to access versions of these datasets on GitHub as these are cleaned and repurposed by other users – including descriptions of the alterations made. This tool requires a GitHub account.

Keywords: big data, public data, Open Data Policy-Managing Information, GitHub

Audience: social scientists, economists, advocacy groups

2.     IPUMS project (Minnesota Population Centre)

https://www.ipums.org/

The Integrated Public Use Microdata Series (IPUMS) is an enormous database of individual level microdata. The data in IPUMS USA is drawn from the United States census, the American Community Survey and the Current Population Survey. IPUMS International includes census data from 73 countries, harmonized to allow comparisons across different times and places.

Combined, these datasets comprise a truly massive resource of census-type information, carefully prepared for ready comparison and interrogation. The website has a built-in SQL selector, a useful FAQ covering the basic questions about the data and its use, and a forum covering more technical questions.

Keywords: IPUMS, Minnesota Population Centre, big data, microdata, census

Audience: population survey researchers, marketers, social scientists, political scientists

3.     The American Economic Association

Due to the huge file sizes involved in many of the Open Science Data Cloud datasets, it is necessary to download UDT, a high-speed data transfer protocol.

Keywords: big data, UDT, UDR, UDP

Audience: data scientists, machine-learning specialists

15.  Datamob

http://datamob.org/

Datamob is a New York-based startup aiming to harness the disruptive potential of public data. The datasets are not actually hosted on the Datamob site; the site itself only links to the original content providers. The data browsing system is visually attractive, although the fact datasets are only indexed alphabetically is a major limitation. The data on Datamob is mostly related to social-causes and activism.

For those interested in communicating through data, Datamob also hosts apps that present data drawn from Datamob sources, giving these and immediate platform.

Keywords: social causes, public data, activism

Keywords: civil society, activism, open data, governance

Audiences: NGOs, civil society organizations, students

17.  Thinknum

http://www.thinknum.com/

Thinknum is a library of financial data, aimed at helping finance professionals build and test models. The site groups together a diverse array of financial data under a single user interface.

Data is grouped according to company name. Analysis is probably best achieved on Thinknum’s own website, but it is also possible to download. Data is retrieved through an HTTP call system, explained on the Thinknum website, that takes a little getting used to.

Keywords: financial data, open data

Audience: financial industry workers, economists

18.  Wikipedia Open Data

http://en.wikipedia.org/wiki/Open_data

While this page neither hosts datasets, nor indexes any datasets, it is an invaluable resource for anyone searching for big open public datasets for big data research. The page contains an introduction to the open data movement, as well as a list of links to the open data resources of 38 governments.

In addition, the subheading “Organizations Promoting Open Data” lists many institutions that maintain their own open data directories.

Keywords: Wikipedia, Wikimedia, big data, social data, pubic data, open data

Audience: students, teachers, economists, social scientists

19.  Open Data Catalogs

http://datacatalogs.org/

DataCatalogs is a registry of open data catalogs from around the world, curated by data experts. The catalog includes open data organizations ranging from local, to state, to national governments, in addition to other open data organizations.

The major weakness of the Open Data Catalogs is its lack of an index, except for a few unhelpful tags. This means if you don’t know exactly what you’re looking for, you will have to wade through a lot of local government listings until you find a treasure.

Keywords: registry, open data, government data

Audience: data scientists, machine learning specialists, urban planners, economists

20.  Commonwealth Scientific and Industrial Research Organization (CSIRO)

http://www.csiro.au/

These are organized exhaustively by theme (many themes containing only one result) and concerned with applied scientific research subjects. The datasets are well described, including all the details of the original research project from which they are drawn, and available data formats depend on the format of the original research data.

Keywords: science, open data, big data

Audience: biologists, chemists, physicists, geologists

21.  Stanford Large Network Dataset Collection

http://snap.stanford.edu/data/

The Stanford Large Network Dataset Collection is a treasure trove for big data researchers interested in network data. Networks are organized according to type, nodes and edges. The datasets are mainly sources from online networks: social networks, online communities, online reviews etc. Though there are also datasets for road networks and scientific collaboration networks.

The files are enormous, and the website does not provide any capacity to analyze them online. These will therefore most likely be suitable for people working in a university or professional capacity.

Keywords: networks, social networks, nodes, edges, graphs

Audience: data scientists, academics, students

22.  GRANIT (State of New Hampshire)

http://library.rice.edu/services/gdc/gis-data/gis-data/copy_of_gis-data-beyond-earth

New Hampshire’s GRANIT is just one of many US state clearinghouses for GIS data. Other databases can be accessed by searching GIS clearinghouse and looking for the various US state names among the results. Many are also listed by Rice University’s library at the previous link.

Together these clearinghouses represent a truly enormous repository of GIS data, which can be used for a variety of GIS projects.

Keywords: GIS data, public data, big data

Audience: geographers, social scientists, conservationists, advocacy groups

23.  University College Dublin Dynamics Lab

http://www.growmeme.com/overview

The Social Network Analysis Interactive Dataset Library from the University of Dublin contains links to data from more than two hundred networks, which will be of interest to social scientists and other social network researchers.

The data can be explored through an interactive visualizer, which displays data according to data of publication, data type and number of datasets. There is also a reference table, which seems to be more reliable.

The datasets are hosted offsite and data formatting is dependent on the host.

Keywords: network, public data, visualizer

Audience: social scientists, sociologists

24.  NASA Shuttle Radar Topography Mission

http://www2.jpl.nasa.gov/srtm/

NASA’s Shuttle Radar Topography Mission (SRTM) contains high-resolution digital topographic information about virtually the entire surface of the planet. Areas of missing data include very high peaks and very deep valleys, thought these represent less than 0.2% of total data.

This data is a great back-end for all sorts of cartographic projects. It is the dataset of choice for Digital Elevation Model data. One example is the following OpenCycle map of world cycle paths.

http://www.opencyclemap.org/

Keywords: GIS, geographic data, NASA, OpenMaps, topography

Audience: geographers, GIS specialists, cartographers

25.  Google Ngram

http://storage.googleapis.com/books/ngrams/books/datasetsv2.html
