Abstract:
1. A method in a computer system with a processor and a memory for calculating importance of documents, the documents having inter-document links, the method comprising: providing an organization of the documents into collections, each collection including a plurality of documents; for each collection, identifying inter-collection links of the documents within the collection, an inter-collection link being a link between a document in one collection and a document in another collection; calculating by the processor importance of each collection by applying a page ranking algorithm to the collections wherein the page ranking algorithm operates on nodes and links, each collection represented by a node and the inter-collection links represented by links between the nodes, to calculate importance for each collection of documents based on the inter-collection links from a document in one collection to a document in another collection; dividing by the processor the collections into a high importance set of collections and a low importance set of collections, wherein the collections of the high importance set of collections have a calculated importance that is above the calculated importance of the collections in the low importance set of collections; after dividing the collection into the high importance set of collections and the low importance set of collections, presenting a combined ranking of the documents in the collections based on the calculated importance of the documents of the high importance set of collections and the calculated importance of the documents of the low importance set of collections.
