System and method for information browsing using multi-modal features
First Claim
1. A method for information browsing using multi-modal features, comprising the steps of:
- automatically isolating a plurality of surface multi-modal features associated with each of a first plurality of objects in a collection, each object in the collection being untagged, the plurality of surface multi-modal features including at least one image mode feature;
generating a feature vector for each of the first plurality of objects from the isolated surface multi-modal features;
searching the collection using a first feature of the plurality of surface multi-modal features to obtain search results;
clustering a second plurality of objects into a plurality of clusters using a second feature of the plurality of surface multi-modal features; and
presenting the clusters to a user.

Abstract
A system and method for browsing, retrieving, and recommending information from a collection uses multi-modal features of the documents in the collection, as well as an analysis of users'"'"' prior browsing and retrieval behavior. The system and method are premised on various disclosed methods for quantitatively representing documents in a document collection as vectors in multi-dimensional vector spaces, quantitatively determining similarity between documents, and clustering documents according to those similarities. The system and method also rely on methods for quantitatively representing users in a user population, quantitatively determining similarity between users, clustering users according to those similarities, and visually representing clusters of users by analogy to clusters of documents.

11. A system adapted for information browsing using multi-modal features, comprising:
-
storage for a document collection, wherein the document collection includes a plurality of untagged documents each having a plurality of multi-modal surface features, the plurality of multi-modal surface features including at least one image mode feature;
a database adapted to store a quantitative representation of each feature corresponding to each document in the document collection;

a computer readable memory storing instructions for causing the processor to browse information, the instructions comprising;
automatically generating a multi-modal feature vector for each document in the collection of untagged documents using the multi-modal surface features;
associating the multi-modal feature vector for each document with the document;
searching the collection using a first feature of the plurality of surface multi-modal features and the multi-modal feature vectors associated with each document in the collection to obtain search results;
clustering a second plurality of documents into a plurality of clusters using a second feature of the plurality of surface multi-modal surface features;
adding documents from the collection to the second plurality of documents based upon closeness of values for the second feature of the plurality of surface multi-modal features;
presenting the clusters to a user. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
