1. A method for abstracting input text into output text having a given maximum length, said method comprising the steps of:
- dividing said input text into a plurality of chunks, said chunks having at least one word;
assigning a significance to said words of a chunk;
assigning a significance to at least some of said plurality of chunks based upon the significance of words contained within said chunks; and
selecting a subset of said chunks for inclusion in said output text based upon the relative significances of said chunks.

Abstract
A text message abstraction system and method allowing for the selection of important pieces of information based upon a number of criteria and for the removal of unnecessary components of a message. The abstraction system of the present invention is provided with an input message, a command set and a maximum message length and attempts to generate a message conveying all of the important information contained within the text message but within the maximum message length constraint.

17. A method for abstracting a textual message consisting of a plurality of words, said abstraction comprising the steps of:
-
dividing said textual message into a plurality of chunks, said chunks having at least one word; classifying said chunks according to predetermined criteria; assigning a significance value to said words according to the classification of the chunk containing said words; assigning a significance value to said chunks according to the total significance values for the words contained in said chunks; writing said chunks to an output buffer in order of significance of said chunks wherein most significant chunks are written to said output buffer prior to any less significant chunks. - View Dependent Claims (18, 19, 20, 21, 22, 23, 41, 42)

24. A paging system comprising:
-
an input source for receiving textual information; a memory operatively connected to said input source for storing said received textual information; text abstraction means for abstracting said received textual information; and a controller communicating with said memory and with said text abstraction means for controlling the operation of said paging system; an output buffer for storing said abstracted textual information. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 43, 44)

32. A device for abstracting a text message, said device comprising:
-
input means for receiving said text message; means for dividing said text message into a plurality of chunks, said chunks having at least one word; means for classifying said chunks according to predetermined criteria; means for assigning a significance value to said words according to the classification of the chunk containing said words; means for assigning a significance value to said chunks according to the total significance values for the words contained in said chunks; an output buffer; and means for writing said chunks to said output buffer in order of decreasing significance. - View Dependent Claims (33, 34, 35, 36, 37, 45, 46)
