Facilitating user communication about a common topic

A computer-implemented method comprising:

• identifying, in first data available to a first user and not available to a second user, and in second data available to the second user and not available to the first user, data pertaining to a common topic;
• sending a communication to the first user that a) indicates that particular data not available to the first user and pertaining to the common topic is accessible upon request and b) identifies the common topic based on identifying, in the first data available to the first user and not available to the second user, and in the second data available to the second user and not available to the first user, the data pertaining to the common topic;
• receiving, from the first user and in response to the communication, a request to access the particular data not available to the first user and pertaining to the common topic;
• and
• enabling the first user and the second user to communicate about the common topic based on identifying, in the first data available to the first user and not available to the second user, and in the second data available to the second user and not available to the first user, the data pertaining to the common topic.

A system comprising:

• a database storing first data available to a first user and not available to a second user, and storing second data available to the second user and not available to the first user
• an analysis engine configured to identify, in the first data and in the second data, data pertaining to a common topic;
• and
• a communication engine to:
• send a communication to the first user that a) indicates that particular data not available to the first user and pertaining to the common topic is accessible upon request and b) identifies the common topic based on the analysis engine identifying, in the first data available to the first user and not available to the second user, and in the second data available to the second user and not available to the first user, the data pertaining to the common topic;
• receive, from the first user and in response to the communication, a request to access the particular data not available to the first user and pertaining to the common topic;
• and
• enable the first user and the second user to communicate about the common topic based on the analysis engine identifying, in the first data available to the first user and not available to the second user, and in the second data available to the second user and not available to the first user, the data pertaining to the common topic.

A computer readable storage device storing a computer program product comprising machine-readable instructions that, when executed, cause a computer system to carry out operations comprising:

• identifying, in first data available to a first user and not available to a second user, and in second data available to the second user and not available to the first user, data pertaining to a common topic;
• sending a communication to the first user that a) indicates that particular data not available to the first user and pertaining to the common topic is accessible upon request and b) identifies the common topic based on identifying, in the first data available to the first user and not available to the second user, and in the second data available to the second user and not available to the first user, the data pertaining to the common topic;
• receiving, from the first user and in response to the communication, a request to access the particular data not available to the first user and pertaining to the common topic;
• and
• enabling the first user and the second user to communicate about the common topic based on identifying, in the first data available to the first user and not available to the second user, and in the second data available to the second user and not available to the first user, the data pertaining to the common topic.
