Title: Does Topic Consistency Matter? A Study of Critic and User Reviews in the Movie Industry
Authors: Eunsoo Kim, MengQi (Annie) Ding, Xin (Shane) Wang, and Shijie Lu
Slide 2
Abstract
This study investigated the relationship between topic consistency and movie demand. The authors
defined topic consistency as the degree of overlap between critic and user review content. They
found that high topic consistency is positively associated with subsequent box office revenue. This
suggests that when critics and users focus on the same aspects of a movie, it is more likely to be
successful.
The authors also found that the effect of topic consistency on demand is the greatest for movies
with mediocre review ratings and when the review ratings from critics are close to those from users.
This suggests that topic consistency is particularly important for movies that are not easily
categorized as either "good" or "bad."
The authors conclude that topic consistency is a valuable metric for predicting movie demand. They
suggest that movie producers and advertisers can use this information to promote their films in a
way that maximizes their chances of success.

Introduction
Movie reviews are an important part of the movie-going experience. They can help consumers make
informed decisions about which movies to watch, and they can also play a role in determining a
movie's success at the box office.
In recent years, there has been a growing interest in the relationship between movie reviews and
movie demand. Some studies have found that positive reviews can lead to increased box office
revenue, while other studies have found no such effect.
This study investigates the relationship between topic consistency and movie demand. Topic
consistency is the degree of overlap between critic and user review content. The authors
hypothesize that high topic consistency will be positively associated with subsequent box office
revenue.
Slide 4
Methods
The authors analyzed data for 1,000 movies released in the United States from 2015 to 2019. They
used a topic modeling algorithm to identify the topics discussed in critic and user reviews. They then
calculated the topic consistency for each movie by measuring the degree of overlap between the
critic and user review topics.

Discussion
The results of this study suggest that topic consistency is a valuable metric for predicting movie
demand. Movie producers and advertisers can use this information to promote their films in a way
that maximizes their chances of success.
For example, movie producers can use topic consistency to identify movies that are likely to appeal
to a wide range of audiences. They can also use topic consistency to target their marketing
campaigns to specific audiences.
Advertisers can use topic consistency to create ads that are relevant to the topics discussed in movie
reviews. This can help to increase the effectiveness of their advertising campaigns.
