Resumo(s)
Online reviews play a significant role in shaping consumer decisions, influencing perceptions,
and serving as key reference points for various choices. The Anna Karenina Principle, derived
from Leo Tolstoy's classic novel, provides valuable insights into success and failure in complex
systems. Recent studies have explored the application of this principle to online reviews in the
tourism and restaurant sectors, focusing on challenges in identifying areas of dissatisfaction
within predominantly positive feedback. By employing state-of-the-art methodologies, such
as BERTopic for topic modeling, this research provides a more transparent view of the
relevance of the Anna Karenina Principle in the context of Portuguese restaurant online
reviews. Building on these insights, this research delves deeper into the success and failure
factors specific to the Portuguese restaurant sector, providing a nuanced understanding of
consumer sentiment and its alignment with the Anna Karenina Principle, particularly in
identifying key factors that contribute to the success and failure of Portuguese restaurants.
