Information on Chilean schools

Description: 
This demo mixes two different datasets: One containing information about schools (location, phone number, etc.) and other containing the SIMCE (a standardized Chilean test) scores of that school over the years.

Comparing Chilean SIMCE test for middle school in each region

Description: 
This demo shows scores in mathematics for a Chilean standardized score by region. The data is complemented by information taken from dbpedia (such as population and geographical positions).
Contributor:

Note: Region's name, latitude and population are taken from dbpedia. For some regions there is no such information so I provide only the URI of those regions.

Data table

This table show the results from the SIMCE (Quality of Education Measurement System, in spanish) together with data obtained from dbpedia. An interesting aspect is that there is information missing in dbpedia about some regions.
Region (dbpedia) Population (dbpedia) Latitude (dbpedia) Avg. math score per region(simce) Avg. language score per region (simce)

Visualizations

The first graph shows the average of Math and Language scores in each region. It is clear that the scores are higher in the central region. A potential explanation if the correlation between population in each region and its score (as you can see in the second graph). Finally, we used dbpedia to obtain the latitude (remember that Chie is roughly speaking a vertical line, so longitudes are more or less the same for each region) and we compared that with the SIMCE results (as can be seen in the third graph). It is possible to do more analysis (in terms of density, ratio of rural/urban population and so on).

Data.gov survey: dataset modification dates compared

Description: 
This demonstration shows when data.gov datasets were last updated, as determined by their HTTP responses. How up-to-date are the datasets listed in data.gov? We start with a time line histogram for a moment in time.
Contributor:
On the afternoons of __ and __, we crawled data.gov's links to datasets and recorded the modification dates reported by the source agency's HTTP servers. Of __ data.gov datasets, __ datasets returned modification dates on __ and __ returned modification dates on __. The list of data.gov datasets came from the 13 Sept 2010 version of their Dataset 92.

Number of Datasets Modified since __


Process used

The following diagram shows the process used to obtain the last-modified dates of the data.gov datasets.

Use of provenance

The following diagram illustrates how the Proof Markup Language was used to record the HTTP headers obtained from the government agency servers. A portion of this data graph is selected by the SPARQL query listed above (the headers are excluded). The red links show the HTTP redirects and HTML anchor hrefs from the data.gov details page to the actual dataset URL on the hosting agency's domain. The green boxes represent URIs for the information obtained (HTTP headers), while the purple boxes associate the information received with its source and when it was received. For more discussion on how provenance is used in LOGD and csv2rdf4lod, see A look at how csv2rdf4lod incorporates provenance into its tabular conversions.

On the afternoon of 21 Sept, 2010, we crawled data.gov's links to data sources and recorded the modification dates reported by the source agency's HTTP servers. Of __ data.gov datasets, __ datasets returned HTTP last-modified dates. The list of data.gov datasets came from the 13 Sept 2010 version of their Dataset 92.

Process used

The following diagram shows the process used to obtain the last-modified dates of the data.gov datasets.

Using the demo: Select a year and a data series to show a heatmap that compares data for different states on a US map (the map may be blank in some combination because impacteen datasets (other than the policy data) only cover data between 1991 and 2007). Select a state to show the evolution of data series from 1991 to 2007.
