1. A computer system for summarization and comparison of sentiment towards one or more entities, the system comprising: a processor and memory configured to execute software instructions embodied within the following components; a content data store that stores a corpus of content gathered from one or more networks; a user request component that receives user requests to summarize and compare entities; an entity summary component that performs an entity summarization by determining a weighted list of relatedness between the entity and each of a provided list of vocabulary words as determined by the corpus in the content data store; a corpus analysis component that analyzes the corpus of content stored in the content data store to determine a ratio of occurrences of a requested entity and each provided vocabulary word versus the total occurrences of the vocabulary word in the corpus; a vocabulary weighting component that assigns a weight to each vocabulary word in the provided vocabulary list based on how frequently each term occurs with the entity name; an entity compare component that handles entity comparisons by performing an entity summarization on each of two received entities and then comparing a weighted vocabulary list for each entity to determine which entity is more associated with the provided vocabulary list; and a user response component that provides results of the summarization and/or comparison in response to the user request.
