Social Scripts02:10

Social Scripts

10.2K
People tend to know what behavior is expected of them in specific, familiar settings. A script is a person’s knowledge about the sequence of events expected in a specific setting (Schank & Abelson, 1977). Essentially, scripts are a particular kind of schema, one containing default values for the features within an event. In the restaurant example, the script's features include the props (e.g., tables, menu, food, and money), the roles to be played (e.g., customer and waiter),...

Social Proof

Social proof is a form of persuasion based on comparison and conformity. People compare their behavior and actions to what others are doing and will change to conform to do what their peers do.

Social Exchange Theory

39.5K
We have discussed why we form relationships, what attracts us to others, and different types of love. But what determines whether we are satisfied with and stay in a relationship? One theory that provides an explanation is social exchange theory. According to social exchange theory, we act as naïve economists in keeping a tally of the ratio of costs and benefits of forming and maintaining a relationship with others (Rusbult & Van Lange, 2003).

Social Traps01:41

Social Traps

26.3K
Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...

Social Facilitation01:04

Social Facilitation

36.0K
Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

Social Loafing01:37

Social Loafing

38.9K
Another way in which a group presence can affect performance is social loafing—the exertion of less effort by a person working together with a group. Social loafing occurs when our individual performance cannot be evaluated separately from the group. Thus, group performance declines on easy tasks (Karau & Williams, 1993). Essentially individual group members loaf and let other group members pick up the slack. Because each individual’s efforts cannot be evaluated,...

Area of Science:

  • Computer Science
  • Information Science

Background:

  • User interactions in online social networks reveal social relationships and user preferences crucial for e-commerce recommendation services.
  • Recommender systems face efficiency challenges due to social data overload, necessitating research into user interaction's impact.

Purpose of the Study:

  • To develop a novel social recommendation method, the SRUI model, enhancing recommender system efficiency.
  • To address the need for applied research on user interaction in the context of social recommendation.

Main Methods:

  • Mapping a weighted social interaction network based on historical user behavior.
  • Utilizing the complete path mining (CPM) algorithm to identify socially similar neighbors.
  • Predicting user ratings by analyzing social similar tendencies within complete paths using the SRUI model.

Main Results:

  • The SRUI model demonstrates superior recommendation performance compared to existing state-of-the-art methods.
  • Experimental results on two public datasets validate the effectiveness of the proposed approach.

Conclusions:

  • The SRUI model offers a robust solution for improving social recommendation efficiency.
  • Leveraging user interaction in complex social networks is key to advancing recommender systems.
