25. A system, comprising: a processor; a storage device to hold content from one or more sources; a memory comprising computer code executed using the processor, in which the computer code implements: generating a user interface that displays analysis results identified from within one or more social media data sources, the user interface comprising: (a) a first interface portion of the user interface comprising a list of one or more analysis results identified from within one or more social media data sources, an individual analysis result from among the one or more analysis results being selectable to display a set of terms associated with a selected individual analysis result in a second interface portion, (b) the second interface portion of the user interface comprising the set of terms, a first interface control, and a second interface control, the set of terms associated with the selected individual analysis result, the first interface control constraining a search to include themes that correspond to the selected individual analysis result, the second interface control constraining the search to exclude the themes that correspond to the selected individual analysis result, and (c) a third interface portion of the user interface comprising a set of one or more semantic filters selected according to the second interface portion; receiving a search criteria to perform a search of content from the one or more social media data sources; performing the search of the content from the one or more social media data sources to generate the list of the one or more analysis results, a volatility index corresponding to a level of commonality between two or more themes being generated for the one or more analysis results, the volatility index usable to automatically control creation of a new topic based at least in part upon a threshold value established for the volatility index, the level of commonality between the two or more themes is calculated by computing centroids for the two or more themes and determining distances between the centroids; displaying the list of one or more analysis results identified from within one or more social media data sources pertaining to the search criteria in the first interface portion of the user interface; receiving a selection of the first or second interface control in the second interface portion of the user interface corresponding to an application of a semantic filter, the semantic filter constraining the search of the content from the one or more social media data sources by: (a) adding the semantic filter to definition parameters for a new topic if the first interface control is selected; (b) adding the semantic filter to the set of one or more semantic filters in the third interface portion of the user interface if the second interface control is selected; and (c) performing a modified search of the content with application of the semantic filter, the modified search updating the list of one or more analysis results identified from within one or more social media data sources in the first interface portion of the user interface to either remove or add results in the first interface portion that pertain to the semantic filter; and creating the new topic based at least in part on the definition parameters, wherein the new topic corresponds to the search criteria and the semantic filter.
25. A system, comprising: a processor; a storage device to hold content from one or more sources; a memory comprising computer code executed using the processor, in which the computer code implements: generating a user interface that displays analysis results identified from within one or more social media data sources, the user interface comprising: (a) a first interface portion of the user interface comprising a list of one or more analysis results identified from within one or more social media data sources, an individual analysis result from among the one or more analysis results being selectable to display a set of terms associated with a selected individual analysis result in a second interface portion, (b) the second interface portion of the user interface comprising the set of terms, a first interface control, and a second interface control, the set of terms associated with the selected individual analysis result, the first interface control constraining a search to include themes that correspond to the selected individual analysis result, the second interface control constraining the search to exclude the themes that correspond to the selected individual analysis result, and (c) a third interface portion of the user interface comprising a set of one or more semantic filters selected according to the second interface portion; receiving a search criteria to perform a search of content from the one or more social media data sources; performing the search of the content from the one or more social media data sources to generate the list of the one or more analysis results, a volatility index corresponding to a level of commonality between two or more themes being generated for the one or more analysis results, the volatility index usable to automatically control creation of a new topic based at least in part upon a threshold value established for the volatility index, the level of commonality between the two or more themes is calculated by computing centroids for the two or more themes and determining distances between the centroids; displaying the list of one or more analysis results identified from within one or more social media data sources pertaining to the search criteria in the first interface portion of the user interface; receiving a selection of the first or second interface control in the second interface portion of the user interface corresponding to an application of a semantic filter, the semantic filter constraining the search of the content from the one or more social media data sources by: (a) adding the semantic filter to definition parameters for a new topic if the first interface control is selected; (b) adding the semantic filter to the set of one or more semantic filters in the third interface portion of the user interface if the second interface control is selected; and (c) performing a modified search of the content with application of the semantic filter, the modified search updating the list of one or more analysis results identified from within one or more social media data sources in the first interface portion of the user interface to either remove or add results in the first interface portion that pertain to the semantic filter; and creating the new topic based at least in part on the definition parameters, wherein the new topic corresponds to the search criteria and the semantic filter. 28. The system of claim 25 , wherein the semantic filter comprises a filter to exclude themes less like selected theme.
