To address “exclude terms” further, “PyeongChang 2018 Olympic Winter Games” brings posts, including a term “gold medal,” a flour manufacturer's name captured in our primary search terms, Gold Medal. The posts about gold medal games, therefore, are excluded by the exclusionary term “Olympics” because they drive a large number of social media activities unrelated to flour. In addition, posts about other baked dishes, such as baked chicken, were removed because they were captured by the search terms “bake” or “baked.” Moreover, “bake” or “cake,” two of the primary search terms, captured or counted posts about the news that a baker refused to make a cake for a gay couple, which brought many social media posts around June 2018. Thus, the term “gay” was included as an exclusionary term to eliminate the large number of posts about cakes for gay weddings.
