15. A computer-implemented method comprising: retrieving, in at least one computing device, a text block from a network site; processing, in the at least one computing device, the text block to generate a plurality of scores, wherein each score of the plurality of scores is in a predefined range of values; determining, by the at least one computing device, that a content of the text block expresses an actionable user concern based at least in part on at least one score of the plurality of scores satisfying a threshold value, wherein the actionable user concern is capable of being addressed by a customer service agent; in response to determining that the content of the text block expresses the actionable user concern, storing, in a memory accessible to the at least one computing device, a representation of the text block in at least one queue of a plurality of queues; and granting access, in the at least one computing device, to the at least one queue of the plurality of queues to generate a message in response to the text block.
