Exploring Computational Linguistics in Computer Science

Join Dr. Carl Alphonce in CSE 111 as we delve into the fascinating world of Computational Linguistics. This week, we will focus on Artificial Intelligence and its application in processing natural human language. We'll cover techniques for spoken and written language, including spelling and grammar checkers, natural language interfaces, and more. We will explore general problem areas like information retrieval, speech recognition, and natural language understanding. Get ready for an insightful discussion that bridges computer science with the intricacies of human communication.

  3. Announcements • HW5 • Part 1 – work on this week • Part 2 – work on next week • due April 16 • 4/5-4/9: Artificial Intelligence • 4/12-4/16: Theory • 4/19-4/23: Exam week

  4. Today’s Agenda • Artificial Intelligence • Computational linguistics • Knowledge representation and reasoning • Game playing

  5. What is Computational Linguistics? • The study of techniques for processing natural human language by computer. • “computational techniques that process spoken and written language, as language” [Jurafsky & Martin,Speech and Language Processing, pg. 2]

  6. Some applications – extant and envisioned • spelling checkers • grammar checkers • natural language interfaces • information extraction • text summarization • conversational agents • machine translation

  7. General problem areas • information retrieval (finding sources) • information extraction (extracting from sources) • speech recognition • natural language understanding • inference (drawing conclusions) • natural language generation • speech synthesis

  8. If only…

  9. Levels of processing • phonetics/phonology – sounds • morphology – word structure • syntax – sentence structure • semantics – meaning • pragmatics – goals of language use • discourse – utterances in context
