Application ID: 11946680

Base Claim:
1. A computer-implemented method comprising: receiving, at a computer device, a collection of text-based strings associated with a document; determining, via the computer device, a set of lexical identifiers for the collection of text-based strings, the set of lexical identifiers comprising one or more lexical identifiers assigned to uniquely represent one or more of the text-based strings of the collection, wherein the one or more lexical identifiers are assigned using a map, wherein, if wholly represented in the map, a text-based string of the collection is represented by a lexical identifier, and, if not wholly represented in the map, the text-based string of the collection is represented using multiple lexical identifiers from the map, wherein the map comprises lexical identifier values such that any text-based string can be represented using either a single lexical identifier or a new lexical identifier created using multiple lexical values of the map.

Claim 6:
6. The method as in claim 1 , wherein, if the text-based string of the collection is not wholly represented in the map, determining the set of lexical identifiers further comprises: identifying that a first portion of the text-based string maps to a first lexical identifier value in the map; identifying that a second portion of the text-based string maps to a second lexical identifier value in the map; and utilizing the first lexical identifier value and the second lexical identifier value to create the new lexical identifier for the text-based string, and including the new lexical identifier in the set of lexical identifiers for the collection of text-based strings.
