  1. Speech Recognition. This involves converting spoken words into text, a crucial task for applications that respond to voice commands.
  2. Part of Speech Tagging. Determining the grammatical category of each word based on its usage and context.
  3. Word Sense Disambiguation. Selecting the correct meaning of a word with multiple interpretations based on context.
  4. Named Entity Recognition (NER). Identifying words or phrases as entities, such as locations or names.
  5. Coreference Resolution. Identifying when two words refer to the same entity, a task extending beyond pronouns to include metaphors and idioms.
  6. Sentiment Analysis. Extracting subjective qualities like attitudes and emotions from text.
  7. Natural Language Generation (NLG). Converting structured information into human language.

NLP tools and approaches

Python, coupled with the Natural Processing Language tool – Natural Language Toolkit (NLTK), emerges as powerful tools for addressing NLP tasks. NLTK encompasses libraries for tasks like part of speech tagging, word segmentation, stemming, lemmatization, and tokenization, aiding in the breakdown of complex language data.

As NLP evolved, statistical approaches, machine learning, and deep learning models entered the scene. The marriage of these technologies allows Natural Language Processing systems to learn from vast amounts of unstructured data, enabling them to continually enhance their understanding and accuracy over time.

Natural Language Processing benefits

Natural Language Processing in AI yields a multitude of benefits, enhancing human-computer communication and facilitating various applications:

  • Improved Accuracy and Efficiency. Natural Language Processing work enhances the accuracy and efficiency of documentation, making it easier to process and understand large volumes of text.
  • Automatic Summarization. Natural Language Processing work allows for the automatic creation of readable summaries from complex original texts, aiding in quick comprehension.
  • Enhanced Personal Assistants. Personal assistants like Alexa leverage Natural Language Processing to understand spoken words, making interactions more intuitive for users.
  • Chatbot-Driven Customer Support. Organizations leverage NLP to implement chatbots for efficient and context-aware customer support.
  • Sentiment Analysis. Natural Language Processing work enables businesses to perform sentiment analysis, extracting valuable insights from the vast pool of textual data.
  • Advanced Analytics. NLP unlocks advanced insights from analytics, allowing any organization to glean information that was previously challenging due to data volume.

Natural Language Processing Examples and Cases

Large foundation models, such as GPT-3, may generalize a large number of tasks without any task-specific training. The latest advancements in this technology represent an important step toward human-level generalization and general artificial intelligence, which are the ultimate aims of most AI research, including those at OpenAI and Google’s DeepMind.
