Summary
Analyzing online discussions reveals that while conversations initially diverge, they tend to converge on popular topics. This study introduces an entity graph to map human communication patterns in social networks.
Area of Science:
- Computational Social Science
- Natural Language Processing
- Cognitive Psychology
Background:
- Online communication generates vast digital data suitable for computational analysis.
- Traditional social network analysis models users as nodes and concepts as flowing between them.
Purpose of the Study:
- To propose an alternative perspective for analyzing online discourse by organizing it into a static concept space called an entity graph.
- To investigate the dynamics of online conversations and their predictability using this novel framework.
Main Methods:
- Extraction and organization of large-scale online discourse from Reddit into an entity graph.
- Quantitative experiments to assess the predictability of conversations.
- Development of an interactive tool to visualize conversation trails over the entity graph.
- Application of the spreading activation function from cognitive psychology.
Main Results:
- Online discourse proved difficult to predict, particularly as conversations progressed.
- Conversations initially diverged broadly across topics but tended to converge towards simpler, popular concepts.
- The entity graph and associated tools provided compelling visual narratives of communication dynamics.
Conclusions:
- The entity graph framework offers a new way to understand online communication by mapping static concepts and dynamic human interaction.
- Despite unpredictability, online conversations exhibit a general trend of topic divergence followed by convergence.
- Computational analysis of digital communication can yield insights into cognitive processes and social dynamics.

5.7K
An ogive graph is sometimes called a cumulative frequency polygon. It is one type of frequency polygon that shows cumulative frequency. In other words, the cumulative percentages are added to the graph from left to right. An ogive graph plots cumulative frequency on the vertical y-axis and class boundaries along the horizontal x-axis. It’s very similar to a histogram; only instead of rectangles, an ogive displays a single point where the top right of the rectangle would be. Creating this...

02:06Social Exchange Theory

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).

The pV diagram, which is a graph of pressure versus volume of the gas under study, is helpful in describing certain aspects of the substance. When the substance behaves like an ideal gas, the ideal gas equation describes the relationship between its pressure and volume. On a pV diagram, it is common to plot an isotherm, which is a curve showing p as a function of V with the number of molecules and the temperature fixed. Then, for an ideal gas, the product of the pressure of the gas and its...

A time-series graph is a line graph with repeated measurements taken at successive intervals of time. It is also called a time series chart. To construct a time-series graph, one must look at both pieces of a paired data set. The horizontal axis is used to plot the time increments, and the vertical axis is used to plot the values of the variable that one is measuring. By using the axes in this way, each point on the graph will correspond to time and a measured quantity. The points on the graph...

01:18Signal Flow Graphs

Signal-flow graphs offer a streamlined and intuitive approach to representing control systems, providing an alternative to traditional block diagrams. These graphs use branches to symbolize systems and nodes to represent signals, effectively illustrating the relationships and interactions within the system.
In a signal-flow graph, branches denote the system's transfer functions, while nodes represent the signals. The direction of signal flow is indicated by arrows, with the corresponding...

01:07Bar Graph

A bar graph is also called a bar chart and consists of bars that are separated from each other. It either uses horizontal or vertical bars to show comparisons among categories. The bars can be rectangles, or they can be rectangular boxes (used in three-dimensional plots). One axis of the graph represents the specific categories being compared, and the other axis shows a discrete value. In this graph, the length of the bar for each category is proportional to the number or percent of individuals...
