19. A system for use in converting contextually indeterminate data from a first form to a second form, comprising: a feature module, comprising non-transitory computer readable instructions stored in a memory that are accessible and executable by a processor of a computer-based string analysis tool, that is operable to represent each of a plurality of schema as a plurality of schema features; an indexing module, comprising non-transitory computer readable instructions stored in a memory that are accessible and executable by a processor of the computer-based string analysis tool, operable to compile an index comprising a mapping, wherein the mapping correlates each schema feature to each one of the plurality of schema containing the schema feature; a similarity metric module, comprising non-transitory computer readable instructions stored in a memory that are accessible and executable by a processor of the computer-based string analysis tool, that is operable to calculate a similarity metric between a set of data to be converted from the first form to the second form, wherein the set of data is contextually indeterminate and each of a selected portion of the plurality of schema has at least one common feature to the source string, wherein the similarity metric comprises a quantitative value regarding the commonality of features between the set of data and each of the selected portion of the plurality of schema; an optimization module, comprising non-transitory computer readable instructions stored in a memory that are accessible and executable by a processor of the computer-based string analysis tool, that is operable to determine the selected portion of the plurality of schema for which a similarity metric is calculated based at least partially on elimination of features from consideration based on a minimum similarity metric threshold; and a conversion module, comprising non-transitory computer readable instructions stored in a memory that are accessible and executable by a processor of the computer-based string analysis tool, that is operable to select, based on the similarity metric between the set of data and each of the selected portion of the plurality of schema to identify at least one selected schema, wherein the conversion module is operable to apply a contextually dependent conversion rule of the selected schema to the set of data to covert the set of data from the first form to the second form.
20. The system of claim 19 , wherein the conversion module operates independently of the context of the set of data to be converted.
