Open access and data processing of Social Media (Twitter) data – a new and valuable consumer research instrument

Thierry Worch, Anne Hasted &Hal MacFie


Overview
Overview data – a new and valuable consumer research instrument

  • Using Twitter for Research – Macro vs Micro

  • The R based macro TwitteR

  • A food product application

  • Possible use in Sensory and Consumer Science

Slide 2


What is twitter
What data – a new and valuable consumer research instrumentis Twitter?

  • Online social network and microblog.

  • Open text-based messages of up to 140 characters also known as “Tweets”.

  • Tweets are open:

    • personal information (what people are doing/feeling);

    • discussions;

    • sharing information...

  • Tweets are grouped together according to their content (use of “#word”).

  • People can “follow” friends, celebrities or brands to stay updated.

  • Over 500 million registered users in 2012, generating over 340 millions tweets/day, and handling over 1.6 billion search queries/day.

Diurnal and seasonal mood vary with work sleep and day length across diverse cultures
Diurnal and Seasonal Mood Vary with Work, data – a new and valuable consumer research instrumentSleep, and Day length Across Diverse Cultures

MACRO APPLICATION 1

  • Study from Golder et al.

  • Science 30 September 2011: 1878-1881.

  • Previous studies small samples of American students.

  • Students are exposed to varying academic schedules that constrain when and how much they sleep.

  • Retrospective self-reports, vulnerable to memory error and experimenter demand effects.

  • Researchers have acknowledged the limitations of this methodology but have had no practical means for in situ real-time hourly observation of individual behavior in large and culturally diverse populations over many weeks.

Slide 4


Methodology
Methodology data – a new and valuable consumer research instrument

2.4 million individuals worldwide

509 million messages February 2008 and January 2010

Twitter data access

Linguistic Inquiry and Word Count (LIWC) Analysis

Negative Term Frequencies

Positive Term Frequencies

Time of day

Slide 6


Results
Results data – a new and valuable consumer research instrument

  • Individuals awaken in a good mood that deteriorates as the day progresses—which is consistent with the effects of sleep and circadian rhythm.

  • Seasonal change in baseline positive affect varies with change in day length.

  • People are happier on weekends, but the morning peak in positive affect is delayed by 2 hours, which suggests that people awaken later on weekends.
