Summer 2018
6/21 -- Downloaded Crunchbase data using API version 3.1, loaded 17 files into crunchbase2 database, checked each table to make sure specs matched new data and updated line counts. Grace and I ran into an issue with blank strings on date types. Date types with "" were not being read as null. We fixed this using a one-line command that we've written on Crunchbase Data. Later we used Connor's master list of 166 accelerators and tried to create a table with accelerators and their uuids by using the 'orgnizations' table. Some names matched multiple times and some did not match at all so we ended up with 179 matches, which we will clean through tomorrow.
6/22 -- Loaded Accelerator Master List as a table and matched on accelerator name or accelerator URL. Manually edited out bad results with same name and different URLs or different URLs and same names. There were 34 entries from the master accelerator list that could not be matched to anything in the crunchbase data table 'organizations'. Grace and I manually searched for these using ILIKE and found a number of matches that we added back into our spreadsheet of matches. Now we have a clean list of accelerator names, their matches from the crunchbase data, and their UUIDs.
6/25 -- Created a table in database crunchbase2 called 'AccUUIDsFinal'. This is a list of 3 columns: accelerator names from the master list, accelerator names from crunchbase, accelerator UUIDs from crunchbase. Then we joined this table back to the needed info fields from crunchbase. This new table is called 'AccAllInfo'. From this table, joining accelerator UUIDs to company UUIDs does not work. This gives investors that have invested in accelerators. From this, Connor and I figured that company_name/company_uuid actually refers to the company being invested in. Joining accelerator names to investor names also gives nothing back. However, when I manually searched Y Combinator as an investor name, I got results back. Not sure what is going on - I think the accelerator names to investor names join should work.
