I recently started working with ontologies and I am using Protege to build an ontology which I'd also like to use for automatically classifying strings. The following illustrates a very basic class hierarchy:
String
|_ AlphabeticString
|_ CountryName
|_ CityName
|_ AlphaNumericString
|_ PrefixedNumericString
|_ NumericString
Eventually strings like Spain
should be classified as CountryName
or UE4564
would be a PrefixedNumericString
.
However I am not sure how to model this knowledge. Would I have to first define if a character is alphabetic, numeric, etc. and then construct a word from the existing characters or is there a way to use Regexes? So far I only managed to classify strings based on an exact phrase like String and hasString value "UE4565"
.
Or would it be better to safe a regex for each class in the ontology and then classify the string in Java using those regexes?
