System and method for online information analysis
First Claim
1. A system comprising:
- a collection engine configured to accumulate document information retrieved from publicly accessible network resources according to predefined subjects; and
an analysis engine configured to analyze the accumulated document information to identify change over a time period in general discussion of a topic within a selected subject of the predefined subjects, the analysis engine further configured to normalize the identified change over the time period based on change in a total number of documents found for the selected subject during the time period.

9. A method comprising:
-
collecting documents from network resources according to predefined subjects to form corpora from the documents according to the predefined subjects;
weighting token values for tokens identified in respective ones of the corpora to increase values of topic-indicating tokens, from the identified tokens, within respective ones of the predefined subjects; and
generating an analysis of prevalence over a time period of one or more words in at least one of the corpora based on the weighted token values. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
