Outliers and Influential Points01:08

Outliers and Influential Points

4.8K
An outlier is an observation of data that does not fit the rest of the data. It is sometimes called an extreme value. When you graph an outlier, it will appear not to fit the pattern of the graph. Some outliers are due to mistakes (for example, writing down 50 instead of 500), while others may indicate that something unusual is happening. Outliers are present far from the least squares line in the vertical direction. They have large "errors," where the "error" or residual is the...

Social Exchange Theory02:06

Social Exchange Theory

36.7K
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 Proof00:52

Social Proof

29.5K
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.

Confidence Coefficient01:24

Confidence Coefficient

8.8K
The confidence coefficient is also known as the confidence level or degree of confidence. It is the percent expression for the probability, 1-α, that the confidence interval contains the true population parameter assuming that the confidence interval is obtained after sufficient unbiased sampling; for example, if the CL = 90%, then in 90 out of 100 samples the interval estimate will enclose the true population parameter. Here α is the area under the curve, distributed equally under...

Group Polarization01:01

Group Polarization

36.4K
Group polarization is the strengthening of an original group attitude following the discussion of views within a group (Teger & Pruitt, 1967). That is, if a group initially favors a viewpoint, after discussion the group consensus is likely a stronger endorsement of the viewpoint. Conversely, if the group was initially opposed to a viewpoint, group discussion would likely lead to stronger opposition.

Area of Science:

  • Social Network Analysis
  • Open Source Systems
  • Knowledge Management

Background:

  • Open-source projects (OSPs) generate substantial semantic content through designer collaboration.
  • Understanding knowledge collaboration dynamics is crucial for OSP development.

Purpose of the Study:

  • To construct and analyze a semantic-based knowledge collaborative network in OSPs.
  • To identify key opinion leaders and assess network robustness under different degradation scenarios.

Main Methods:

  • Constructed a directed, weighted, semantic-based knowledge collaborative network.
  • Utilized social network analysis, entropy weight, and TOPSIS to identify opinion leaders.
  • Developed three degradation modes and a susceptible-infected-removed (SIR) model for opinion leader influence.
  • Conducted dynamic robustness analysis on empirical data from Local Motors OSP community.

Main Results:

  • Network robustness varied significantly across degradation modes.
  • Degradation of opinion leaders' collaborative behavior resulted in the lowest network robustness.
  • Main knowledge dissemination and contribution behaviors showed intermediate robustness.
  • Random behavior degradation exhibited the highest network robustness.

Conclusions:

  • The study reveals the differential impact of node type degradation on network robustness in OSPs.
  • Findings can inform management strategies for open-source communities to ensure stable development.
  • Identifying and supporting opinion leaders is critical for maintaining network integrity.
