Predicting individual or crowd behavior based on graphical text analysis of point recordings of audible expressions

1. A computer program product, comprising:

a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions readable by a processing circuit to cause the processing circuit to perform a method of determining a crowd behavior, the method comprising:

collecting, at one or more recording points in a crowd of individuals, audible expressions that the individuals of the crowd make;

generating 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 a crowd behavior by performing a graphical text analysis on the graph; and

outputting 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 computer program product 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 computer program product 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 computer program product of claim 1 , wherein the crowd control measure is for assisting the crowd in minimizing a risk the crowd behavior has.

5. The computer program product of claim 1 , wherein the audible expressions of the individuals are collected as the individuals approach or pass by the recording points.

6. A computer program product, comprising:

a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions readable by a processing circuit to cause the processing circuit to perform a method of determining a crowd behavior, the method comprising:

collecting, at one or more recording points in a crowd of individuals, audible expressions that the individuals of the crowd make;

generating 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 a crowd behavior by performing a graphical text analysis on the graph;

outputting 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 computer program product of claim 1 , wherein the method further comprises:

collecting text messages that the individuals send; and

using the text messages to generate the graph.

8. The computer program product of claim 1 , wherein the recording points comprise a screening checkpoint, wherein the method further comprises:

determining a behavior of an individual or a behavior a group of individuals of the crowd by performing the graphical text analysis on the graph; and

outputting an indication of the determined individual or group behavior to trigger a security measure.

9. A computer system for determining a crowd behavior, the system comprising:

a memory having computer readable instructions; and

a processor configured to execute the computer readable instructions, the instructions comprising:

collecting, at one or more recording points in a crowd of individuals, audible expressions that the individuals of the crowd make;

generating 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 a crowd behavior by performing a graphical text analysis on the graph; and

outputting 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.

10. The computer system of claim 9 , 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.

11. The computer system of claim 9 , wherein the method further comprises:

collecting audible expressions from phone calls that the individuals make; and

using the audible expressions collected from the phone calls to generate the graph.

12. The computer system of claim 9 , wherein the method further comprises:

collecting text messages that the individuals send; and

using the text messages to generate the graph.

13. The computer system of claim 9 , wherein the recording points comprise a screening checkpoint, wherein the method further comprises:

determining a behavior of an individual or a behavior a group of individuals of the crowd by performing the graphical text analysis on the graph; and

outputting the determined individual or group behavior to trigger a security measure.
