14. The system of claim 13 , wherein the semantic layer includes an Artificial Intelligence (AI) engine configured to modify the received query into a predetermined structure, wherein disseminating the query comprises: receiving, from the second individual, input responsive to requesting the second individual to provide a second characterization of the skill level of the first individual in the target skill set; and upon programmatically determining that the second characterization confirms the first characterization of the skill level of the first individual in the target skill set, generating output identifying the first individual and specifying the confirmed first characterization of the skill level of the first individual in the specified skill, wherein the output is returned to the source.
13. A system to determine individuals having target skills, the system comprising: one or more computer processors; at least one memory, the at least one memory containing a program executable by the one or more computer processors, the program including: a semantic layer configured to receive a query from a source, the query seeking names of individuals having a target skill set including one or more skills; a knowledge management system (KMS) layer configured to represent a body of knowledge including information pertaining to a first individual in the target skill set, wherein the information includes a first characterization of a skill level of the first individual in the target skill set, wherein the first characterization is determined based on input from a plurality of individuals, wherein the query is composed according to a query language not supported by the first layer, wherein the query is reformulated into a different query language supported by the first layer; and a collaboration layer configured to, upon determining that a count of the plurality of individuals is less than a predefined count of individuals characterizing the skill level of the first individual, confirm the skill level of the first individual by disseminating the query to at least a second individual in a social network for soliciting responses to the query and for verification of the responses, wherein the second individual is not included in the plurality of individuals.
