1. A method for generating shorter versions of one or more sentences, the method comprising: receiving, by a computing device, the one or more sentences from a text; based on the one or more sentences, generating, by the computing device within a memory of the computing device, a tree comprising a plurality of nodes; wherein the tree represents the one or more sentences; wherein each node, of the plurality of nodes, represents a grammatical element of the one or more sentences; using a named entity recognizer, automatically recognizing which nodes, of the plurality of nodes, represent grammatical elements that correspond to recognized named entities; selecting a particular node from the tree based, at least in part, on (a) which nodes in the tree correspond to recognized named entities, (b) a position of the particular node within the tree, and (c) a node type of the particular node; wherein the particular node has no children within the tree that correspond to recognized named entities identified by the named entity recognizer; after said selecting, modifying the tree within the memory of the computing device by removing the particular node and children of the particular node from the tree; after removing, from the tree, the particular node and the children of the particular node, generating, from remaining nodes of the tree a first set of one or more sub-sentences; wherein the first set of one or more sub-sentences are shorter in length than said one or more sentences; causing display of at least one sub-sentence generated from remaining nodes of the tree to a user.

The method of claim 1 , wherein the tree represents a grammatical structure of the one or more sentences and wherein said step of selecting is further based on the grammatical structure of the one or more sentences represented by the tree.
