Abstract
The present invention relates to summarization of a document. The method includes receiving texts of the document and a submodular function for defining an amount of information of a subset of the document as a summary of the document, generating a dependency structure tree representing a dependency structure of sentences in a document, identifying a set of paths including the root of the dependency structure tree, recursively selecting a paths using a greedy algorithm for maximizing the submodular function, and outputs a subset with the maximum amount of information as a the summary of the document.
