Abstract: A method and system is disclosed for determining the changes in valuation of an asset of interest and then using high or low betweeness centrality values as an indicator for near term future changes in asset value. The present invention searches a broad set of electronically based documents, such as Web pages, blog entries, and online forum posts that are relevant to the asset of interest, in a manner that identifies the interlinking characteristics between the documents. It also weights query terms (=asset of interest) by information retrieval metrics, and calculates the sentiment of their context.
