PROMT Syntactic and Semantic Analyzer

PROMT Syntactic and Semantic Analyzer is a Windows program that performs a deep morphological, syntactic, and semantic parsing for a given text in natural language. The following languages are supported as of October 2012:

  • English
  • French
  • Spanish
  • Italian
  • Portuguese
  • Russian

PROMT Syntactic and Semantic Analyzer interprets sentences of any level of complexity and nesting. As PROMT has been developing machine translation (MT) engines for over 20 years, it has created advanced algorithms for natural languages analysis that can be used not only for MT but also for data mining, text search, and abstracting systems.

The default linguistic database contains 30+ million word forms and allows entering new words and patterns such as new semantic classes or user-defined syntactic patterns. The toolkit for entering new classes and patterns can be delivered to the client together with PROMT Syntactic and Semantic Analyzer.

The default output from every given sentence is as follows (and can be extended, if needed):

  • Borders of a composite sentence
  • Borders of clauses within the composite sentence
  • Syntactic groups within the sentence (noun groups, verb groups, etc.)
  • The output for every lexical item:
    • Part of speech (noun, adjective, verb, etc.)
    • Grammatical form with extended morphological and syntactic characteristics. For example:
      • For nouns: gender, number, semantic marker, animate/inanimate object, etc.
      • For verbs: person, number, tense, gender, voice, mood, reflexivity, transitivity, semantic marker, etc.
    • Syntactic role in the sentence (subject, predicate, object, etc.)
    • Initial form
  • Identification of special lexical items such as people, dates, locations, etc.

The output format is XML which can be easily analyzed. The product kit also contains a tool to visualize the analysis output for human expert evaluation.
