Abstract
A system, method, and computer program product retrieve information associated with the signals. The information retrieval can be performed on a signal by quantizing the signal, forming words, and indexing based on weights of the words. The words are formed by grouping letters together to form a number of words within predetermined threshold values. The weights of the words are determined using a binomial log likelihood ratio analysis. The present invention may be applied to identification of an unknown song.
Claims40
A computer-implemented method comprising:
- accepting a file and information corresponding to the file;
- associating the file and the information corresponding to the file;
- organizing the file into at least one document comprising at least a portion of the file;
- associating the file and the document corresponding to the file;
- quantizing the document to obtain letters;
- grouping the letters to form a set of words, the set being based on a predetermined frequency of occurrence of the grouped letters;
- associating each document and the corresponding set of words in an index of documents;
- obtaining a set of query words;
- identifying one or more documents in the index, each of the identified documents containing at least one query word in the set of query words;
- and
- scoring each of the identified documents, a score for each identified document being based at least in part on a weighting of each query word found in the identified document, the weighting being determined using a local weighting factor and a global weighting factor.
