Interface Application.NLP

Enclosing class:
Application
public static interface Application.NLP
The common set of applications for natural language processing (text data).

  • Field Details

    • ANY

      static final Application ANY
      Any NLP application, including those in Application.NLP.

    • FILL_MASK

      static final Application FILL_MASK
      An application that masking some words in a sentence and predicting which words should replace those masks.

    • QUESTION_ANSWER

      static final Application QUESTION_ANSWER
      An application that a reference document and a question about the document and returns text answering the question.

      The typical signature is Model<QAInput, String>.

    • TEXT_CLASSIFICATION

      static final Application TEXT_CLASSIFICATION
      An application that classifies text data.

      The typical signature is Model<String, Classifications>.

    • SENTIMENT_ANALYSIS

      static final Application SENTIMENT_ANALYSIS
      An application that classifies text into positive or negative, a specific case of TEXT_CLASSIFICATION.

    • TOKEN_CLASSIFICATION

      static final Application TOKEN_CLASSIFICATION
      A natural language understanding application that assigns a label to some tokens in a text.

    • WORD_EMBEDDING

      static final Application WORD_EMBEDDING
      An application that takes a word and returns a feature vector that represents the word.

      The most representative signature is Model<String, NDArray>. However, many models will only embed a fixed Vocabulary of words. These words are usually given integer indices which may make the signature Model<String, NDArray> (or NDArray). The signatures may also use singleton NDLists instead of NDArray.

    • TEXT_GENERATION

      static final Application TEXT_GENERATION

    • MACHINE_TRANSLATION

      static final Application MACHINE_TRANSLATION
      An application that translates text from one language to another.

      The typical signature is Model<String, String>.

    • MULTIPLE_CHOICE

      static final Application MULTIPLE_CHOICE
      An application to represent a multiple choice question.

    • TEXT_EMBEDDING

      static final Application TEXT_EMBEDDING
      An application that takes text and returns a feature vector that represents the text.

      The special case where the text consists of only a word is a WORD_EMBEDDING. The typical signature is Model<String, NDArray>.
