Abstract: A computer-implemented system and method for providing a ranking of content is disclosed. A computer processor is configured to access ranked listing content from one or more electronic sources. A database is connected to the processor and configured to store information related to the content. A software-implemented parsing module is configured to parse text of the content into individual words. A software-implemented counting module computes an appearance frequency for each word. A software-implemented ranking module associates a ranking with a parsed word. A software-implemented topic module identifies the content items in the snapshot containing a word and the associated rank of each such content item in the ranked listing in which it appears. A software-implemented content index module forms an index ranked list by computing an aggregate grouping score from the ranking. A display device is connected to the processor and configured to display the ranking associated with a word.
