Hubs: Hubs Data

List of Variables

For a more in-depth of the variables and procedure please see: Hubs: Mechanical Turk. This page will reflect the variables being collected separated into three categories. Each variable will include a breakdown of levels being collected if the definition is not trivial and an approximate approach.

As of Week of 7/25

Group 1

Variables Difficult to Obtain

1. Founding Date (date_founded)
   • Difficulty: Finding date based on our strategies
   • New Approach:
     1. Whois.net Date
     2. Factavia/other press release searches
2. Multiple locations within city + Franchise (as of now just addresses) (multi_address)
   • Difficulty: Company or establishment level will impact measurements
   • New Approach: Will record all addresses at company level
3. Onsite Venture Capital v. Angel Investors (e.g. # and Assets Under Management) (onsite_Vc_bin)/(onsite_vc_list) (onsite_angel_bin)/etc.
   • Levels: Binary, list of investors
   • Difficulty: Hub website usually does not include investors
   • New Approach:
     1. Google key terms with address of Hub
     2. Start with partners and use google/crunchbase

Group 2

Variables Comfortable, Not Complete (rough order of most difficult to least difficult)

1. Onsite accelerator (onsite_accel_bin)/(onsite_accel_cnt)/(onsite_accel_list)
   • Levels: Binary, count, list
   • Difficulty: Usually not a list, which requires more scrubbing as many other variables just require us to find one page on a website.
   • Approach:
     1. Google searches and procedure to use on website yields decent results
     2. Similar procedure to onsite investors
2. Size (# members) (num_members)
   • Levels: Count for companies (currently not planning to include list of companies given that some potential hubs have 200+ members)
   • Difficulty: Some companies don’t list all members - only selective ones-, others do not separate current members and alumni, and some just write "we have served more than 120 startups..."
   • Approach: For companies that have a list, we will count. For those with select members, we will count those they listed and try to see if there is a comment about how many they have. For those that just have a statement "with over," we will write the number and + (e.g. "120+).
3. Office hours investors and Office hours mentor/advisors (OH_bin)/(OH_inv_bin)/(OH_inv_list)/etc.
   • Levels: Binary for OH, binary for two separate OH, list of names/descriptions of OH
   • Difficulty: Some companies do not list who OH are with, not always obvious if investor, mentor, or advisor, sometimes not clear if mentor is investor/future investor
   • Approach: Google approach to get to OH pages and then lookup key words in description to separate out
4. Onsite temporary workshops and Networking Meetups (Count) (onsite_temp_events_bin)/(onsite_temp_workshop_bin)/(onsite_temp_workshop_cnt)/etc.
   • Levels: Binary for do they exist, count for each
   • Difficulty: Difficult for Turkers to differentiate between these two and also other potential events (e.g. symposiums)
   • Approach: Uses key search terms (e.g. Java/etc.) to separate out workshops and key terms (e.g. lunch/happy hour) for networking meetings
5. Onsite code school and Curriculum (onsite_long_term_courses)/(onsite_code_school_bin)
   • Levels: Binary for do they exist, binary for each
   • Difficulty: Difficult for Turkers to differentiate between long-term coding programs for individuals and curriculum for startups
   • Approach: Uses key search terms (e.g. specific code schools) to separate out known code schools and also to look into key terms (e.g. leadership) for curriculum
6. Sponsors/Partners (University, Corporate) (sponsors_cnt)/(sponsors_list)/etc.
   • Levels: Count, list of sponsors/partners (if exist), separate columns for university and corporate
   • Difficulty: Not all companies will list sponsors, partnesrs, or either. Not always clear the difference among sponsors, partners, investors.
   • Approach: Use two different levels and use of google search, then if list exists, separate by "college"/"university" and rest
7. Alumni Network (alumni_bin)/(alumni_list)
   • Levels: Binary, list
   • Difficulty: Not all companies list alumni, some only list "selected"
   • Approach: Include all that have lists
8. Size (sqft) (size_sqft)
   • Levels: Number in sqft
   • Difficulty: Not all companies list square feet online
   • Approach:
     1. Google search with key words
     2. If results do not appear, use of press releases is possible
9. Onsite Mentors (onsite_mentors_bin)/(onsite_mentors_cnt)/(onsite_mentors_list)
   • Levels: Count and list of mentors (if exist)
   • Difficulty: Not all companies list mentors - bigger issue is onsite investors
   • Approach: Use two different levels and use of google search

Group 3

Variables Easy to Obtain

1. Twitter activity (twit_handle)/(twit_prev_mon_cnt_tweets)/(twit_cnt_followers)/(twit_cnt_retweets)
   • Levels: Twitter Handle, # Tweets in a Month, # Followers, # Retweets
   • Approach: Easy to get twitter handle from Turk or Veeral's code that allows us to run a series of searches on google and then use Gunny's Twitter crawler to get other levels from handle
2. Site URL (url)
   • Levels: URL
   • Approach: Google using Veeral's code that allows us to search
3. Whois Date (date_whois)
   • Levels: Date
   • Approach: Date active website was registered
4. Address (address)
   • Levels: Will include all addresses
   • Approach: Google key terms (e.g. Contact Us) and URL using Veeral's code
5. Nonprofit status (nonprofit_binary)
   • Levels: Binary variable indicating if the potential Hub is a nonprofit organization
   • Approach: http://www.guidestar.org/ is a site that we can use to search if a company is nonprofit or not
6. Mission statement (missions_stmt)
   • Levels: Official mission statement or description of company (if mission does not exist)
   • Approach: If not explicitly stated mission statement, will include "About" or statements on main page
7. Specific Industry (spec_industry)
   • Levels: Industry included in statement (no aggregation)
   • Approach: *Based on Mission Statement, not aggregated
8. Price for a space/office (price_space)
   • Levels: Two prices one for shared, other for private
   • Approach: Uses google methodology with key terms and URL
