Study Notes
Definition and Goal of NLP
- NLP is an interdisciplinary subfield of computer science and linguistics, focusing on enabling computers to support and manipulate human language.
- The goal is to create a computer that can "understand" document contents, extract information, and categorize and organize documents accurately.
Challenges in NLP
- Speech recognition, natural-language understanding, and natural-language generation are common challenges in NLP.
History of NLP
- Roots of NLP date back to the 1940s, with Alan Turing's 1940 article "Computing Machinery and Intelligence".
- Turing proposed the Turing test, which involves automated interpretation and generation of natural language.
Approaches to NLP
Symbolic NLP (1950s – early 1990s)
- Based on hand-written rules, similar to John Searle's Chinese room experiment.
- Computers emulate natural language understanding by applying rules to data.
Statistical NLP (1990s–2010s)
- Introduction of machine learning algorithms for language processing in the late 1980s.
- Shift from rule-based to statistical approaches, driven by increased computational power and decline of Chomskyan theories.
Neural NLP (present)
- Emergence of neural networks and deep learning in NLP, achieving state-of-the-art results.
- Word2vec, a neural network-based approach, became popular in the 2010s.
Applications of NLP
- NLP is increasingly important in medicine and healthcare, helping to analyze electronic health records and protect patient privacy.
