1. A method implemented by a computing system in response to execution of program code by a processor of the computing system, comprising: receiving first data content; generating a first semantic representation of the first data content; determining whether the first semantic representation is similar to a second semantic representation of second data content; if the first semantic representation is similar to the second semantic representation, generating a third semantic representation based on the first semantic representation and on the second semantic representation, and associating the third semantic representation with the first data content and with the second data content; if the first semantic representation is not similar to the second semantic representation, associating the first semantic representation with the first data content; displaying a first view of a graphical interface, the first view of the graphical interface including a list that includes a plurality of members each being selectable by a user and corresponding to a respective semantic representation, each one of the plurality of members including an indication of data content associated with the semantic representation to which the one of the plurality of members corresponds, each one of the plurality of members indicating a number that reflects a number of additional content references that are associated with the semantic representation to which the one of the plurality of members corresponds; wherein if the first semantic representation is similar to the second semantic representation and the third semantic representation is associated with the first data content and with the second data content: a first one of the plurality of members in the list corresponds to the third semantic representation associated with the first data content and with the second data content, the first one of the plurality of members including an indication of the first data content, the first one of the plurality of members indicating a number that reflects a number of additional content references that are associated with the third semantic representation, one of the additional content references associated with the third semantic representation being the second data content; the method further comprising: after selection of one of the plurality of members in the list of the first view, displaying a second view of the graphical interface, the second view of the graphical interface including text of the data content that is associated with the semantic representation to which the selected one of the plurality of members corresponds, the second view of the graphical interface further including a list of entries each being selectable and associated with a respective one of the additional content references that are associated with the semantic representation to which the selected one of the plurality of members corresponds; wherein if the selected one of the plurality of members is the first one of the plurality of members: the text of the data content included in the second view comprises text of the first data content, and the list of entries that are selectable and included in the second view includes an entry associated with the second data content.
