Summary
This study on Spanish TripAdvisor reviews found that adjectives and sentiment words in single-word titles reduce polarity judgment variation. Neutral words, however, increase variation, with effects diminishing in longer titles.
Area of Science:
- Natural Language Processing (NLP)
- Computational Linguistics
- Sentiment Analysis
Background:
- Crowdsourced data, like TripAdvisor reviews, is crucial for NLP tasks, especially sentiment analysis.
- Understanding factors influencing polarity judgments in Spanish reviews is essential for accurate NLP applications.
Purpose of the Study:
- To investigate factors affecting polarity judgment variation in Spanish TripAdvisor reviews.
- To test the influence of Part Of Speech (POS), sentiment words, and neutral words on judgment variation.
Main Methods:
- Analysis of one-word titles from Spanish TripAdvisor reviews.
- Statistical tests on mean equality for different word groups (POS, sentiment, neutral).
- Comparison of results from one-word titles versus longer titles.
Main Results:
- Adjectives and sentiment words in one-word titles significantly reduce polarity judgment variation.
- Neutral words are associated with higher judgment variation.
- Observed effects are less consistent in longer titles due to contextual influences.
Conclusions:
- One-word titles are effective for studying isolated word polarity, while longer titles introduce confounding factors.
- Findings provide insights for NLP practitioners and researchers working with Spanish sentiment analysis.

14.7K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

00:56Attribution Theory

Behavior is a product of both the situation (e.g., cultural influences, social roles, and the presence of bystanders) and of the person (e.g., personality characteristics). Subfields of psychology tend to focus on one influence or behavior over others. Situationism is the view that our behavior and actions are determined by our immediate environment and surroundings. In contrast, dispositionism holds that our behavior is determined by internal factors (Heider, 1958).

01:25Factors Affecting Perception
1.6K
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.

Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Attitude is our evaluation of a person, an idea, or an object. We have attitudes for many things ranging from products that we might pick up in the supermarket to people around the world to political policies. Typically, attitudes are favorable or unfavorable: positive or negative (Eagly & Chaiken, 1993). And, they have three components: an affective component (feelings), a behavioral component (the effect of the attitude on behavior), and a cognitive component (belief and knowledge;...

Measures of variability are statistical metrics that reveal the dispersion pattern within a dataset. They are pivotal in biostatistics, providing insights into the heterogeneity within health and biological data. Variability signifies the degree to which data points diverge from one another, helping researchers understand the potential range of values and associated uncertainty within the data.
