1. A method comprising:

  • parsing, by a computer-based system for extracting semantic tags from text, a body of text by determining a language and structure of the body of text;

    tokenizing, by the computer-based system, the body of text by splitting the body of text into individual tokens;

    generating, by the computer-based system, a tagged body of text by assigning each individual token a part-of-speech tag indicating a grammatical role of the individual token, wherein the grammatical role includes one of a noun, a pronoun, a verb, an adverb, an adjective, a conjunction, a preposition, an article, an auxiliary verb, an infinitive, an interjection, modal verb, an object, a participle, a phrase, and a predicate;

    splitting, by the computer-based system, the tagged body of text into grammatical chunks;

    identifying, by the computer-based system, named entities within the body of text;

    resolving, by the computer-based system, the individual tokens having a pronoun grammatical role with corresponding noun phrases;

    deciding, by the computer-based system, a context and purpose of the body of text, and translating semantic concepts of the body of text into one or more semantic tags;

    identifying, by the computer-based system, one or more communication topics and presuppositions of the body of text, wherein the identifying the one or more communication. topics and presuppositions comprises analysis of prior communications within the body of text to facilitate the tokenizing the body of text; and

    generating, by the computer-based system, a list of the one or more semantic tags.
