The TD_NERExtractor function performs Named Entity Recognition (NER) on input text according to user-defined dictionary words or regular expression (regex) patterns.

TD_NERExtractor can be used to match and label specific elements within a given input text. The function identifies the contents of the text by matching extracts from the text to specific words (dictionary) or string patterns using regular expressions.
