Social Identity01:29

Social Identity

14
Social identity constitutes a significant aspect of an individual’s self-concept, shaped by membership in various social groups, including gender, nationality, ethnicity, sexual orientation, and political affiliation. Individuals associate specific traits with particular social groups, leading to internalization of these traits. For example, musicians are often perceived as creative, while women are frequently associated with nurturing tendencies. Once individuals identify with a...

In- and Out-Groups

People all belong to a gender, race, age, and social economic group. These groups provide a powerful source of our identity and self-esteem (Tajfel & Turner, 1979) and serve as our in-groups. An in-group is a group that we identify with or see ourselves as belonging to.

Social Loafing

36.3K
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,...

Surveys

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Area of Science:

  • Social Network Analysis
  • Community Detection Algorithms
  • Data Mining

Background:

  • Realistic social communities are complex, multi-profiled structures based on shared traits.
  • Dense, holonic cross-communities are significant due to their granular and distinguishable interests.
  • Existing methods often overlook community granularity in detection.

Purpose of the Study:

  • To develop a novel methodology for detecting the smallest, most granular multi-profiled cross-community.
  • To introduce a system, ID_CC, for implementing this methodology.
  • To enhance the accuracy of cross-community detection by addressing missing links.

Main Methods:

  • Developing a novel methodology for granular multi-profiled cross-community detection.
  • Implementing the methodology in a system named ID_CC.
  • Uncovering missing links in social networks to improve detection accuracy.

Main Results:

  • Experimental evaluation of ID_CC against eight existing methods.
  • Demonstrated marked improvement in detecting granular multi-profiled cross-communities.
  • ID_CC effectively identifies smallest and most granular communities.

Conclusions:

  • The proposed methodology and ID_CC system significantly advance the detection of granular multi-profiled cross-communities.
  • Addressing missing links is crucial for accurate social network community analysis.
  • ID_CC offers a more precise approach to understanding user communities.
