Predicting individual or crowd behavior based on graphical text analysis of point recordings of audible expressions
Embodiments relate to determining a crowd behavior. A method of determining a crowd behavior is provided. The method collects, at one or more recording points in a crowd of individuals, audible expressions that the individuals of the crowd make. The method generates a graph of the audible expressions as the audible expressions are collected from the individuals. The method determines a crowd behavior by performing a graphical text analysis on the graph. The method outputs an indication of the crowd behavior to trigger a crowd control measure.
1. A computer-implemented method for determining a crowd behavior, comprising:
collecting, via a computer processor, at one or more recording points in a crowd of individuals, audible expressions that the individuals of the crowd make;
generating, via a computer processor, a graph of the audible expressions as the audible expressions are collected from the individuals, wherein the graph comprises nodes that represent tokens and edges that represent temporal precedence in the audible expressions;
determining, via a computer processor, a crowd behavior by performing a graphical text analysis on the graph; and
outputting, via a computer processor, an indication of the crowd behavior to trigger a crowd control measure, wherein the crowd behavior comprises a risk metric, and wherein the crowd control measure is triggered when the risk metric is above a threshold.
2. The method of claim 1 , wherein the determining comprises:
performing the graphical text analysis on the graph to identify at least one of a cognitive stage of each individual, a cognitive state of a group of individuals of the crowd, and a cognitive state of the crowd as a whole; and
determining the crowd behavior based on the identified cognitive state.
3. The method of claim 1 , wherein the crowd control measure is for deterring the crowd behavior if the crowd behavior is determined to be a risk.
4. The method of claim 1 , wherein the outputting comprises providing an alert to an individual who implements the crowd control measure.
5. The method of claim 1 , wherein the at least one of the recording points moves in the crowd.
6. A computer-implemented method for determining a crowd behavior, comprising:
collecting, via a computer processor, at one or more recording points in a crowd of individuals, audible expressions that the individuals of the crowd make;
generating, via a computer processor, a graph of the audible expressions as the audible expressions are collected from the individuals, wherein the graph comprises nodes that represent tokens and edges that represent temporal precedence in the audible expressions;
determining, via a computer processor, a crowd behavior by performing a graphical text analysis on the graph;
outputting, via a computer processor, an indication of the crowd behavior to trigger a crowd control measure;
collecting audible expressions from phone calls that the individuals make; and
using the audible expressions collected from the phone calls to generate the graph.
7. The method of claim 1 , further comprising:
collecting text messages that the individuals send; and
using the text messages to generate the graph.
