Search for data tables.

Project description

When we search for ordinary written documents, we send words into a search engine and get pages of words back.

What if we could search for spreadsheets by sending spreadsheets into a search engine and getting spreadsheets back? The order of the results would be determined by various specialized statistics; just as we use PageRank to find relevant hypertext documents, we can develop other statistics that help us find relevant spreadsheets.

To index a new spreadsheet, run this.

, --index [csv file]

For example,

, --index /home/tlevine/Math Scores 2009 Copy (1).csv \

Caches from the indexing process are stored in the ~/., directory.

By default, CSV files that have already been indexed will be skipped; to index the same CSV file again, run with the --force or -f option.

, --index --force [csv file]

Once you have indexed a bunch of CSV files, you can search.

, [csv file]

You’ll see a bunch of data tables as results.

$ , 'Math Scores 2009.csv'
/home/tlevine/Math Scores 2009.csv
/home/tlevine/Math Scores 2009 Copy (1).csv

To do

  • Add non-exact column matches so that there can be more matches.

  • Store distributions of values (collections.Counter objects) instead of just distinct values (set objects) so that I can run more interesting comparisons.

  • Store a preview of the table in the db or load it from the cache so that the web interface can show the preview.
