Presentation Transcript

  1. Institute for Language, Cognition, and Computation (ILCC) www.inf.ed.ac.uk

  2. Broad and Deep Strength in Research • Natural language processing and computational linguistics (SMT, web mining, parsing ...) • Spoken language processing • Dialogue and multimodal interaction • Information extraction, retrieval and presentation • Computational models of human cognition • Educational and assistive technology • http://wcms.inf.ed.ac.uk/zope/iccs/research www.inf.ed.ac.uk

  3. Example: Machine Translation • Develop and maintain Moses (> 450 downloads/month) • Dominant academic platform for statistical MT • Deployed commercially (e.g., Asia Online) • Directly influenced Google's Language Model • Group focus: • Large scale data (randomisation and streaming) • Novel machine learning methods for translation • Linguistics in translation www.inf.ed.ac.uk

  4. Machine Translation: Aiding human translators

  5. Example: Social Media Finding events mentioned In Twitter, in real time and at scale > 500 Million Tweets, > 1 Million Tweets/day

  6. But the web is not all text • Image Retrieval: • Number of image collections is rapidly growing • Increasing demand for browsing and searching • Manual search is too costly • Retrieval Methods: • Image content-based retrieval system --> good query images • Text query-based retrieval --> annotated databases • Goal: Automatic image annotation • Exploit resources where images and annotations co-occur naturally (e.g., Wikipedia, Flickr) • News articles associated with images and their captions (BBC News Database) • caption describes image content directly or indirectly • document describes the content of the image • Use machine learning to associate images with keywords

  7. Example: Image annotation Afghanistan, troop, Blair, British, NATO, helicopter, soldier, support, operation, commander Troops need more Chinook helicopters to carry out operations

  8. Social Media: Model Prediction Market using Tweets (“Will Swine Flu become A Pandemic?”)

  9. Example: Speech Recognition and Synthesis • Internationally known for speech synthesis and recognition • Speaker-adaptive speech synthesis • Recognition of multi-party conversation • Developed principal open source toolkit for speech synthesis research (Festival) • Co-ordinate the only international evaluation campaign for speech synthesis • Spinoffs • Text-to-speech: Rhetorical systems, Cereproc • Speech recognition: Quorate Technology (pre-spinout stage) • World leader in speaker-adaptive speech synthesis • EU FP7 EMIME Project; voice re-construction

  10. Demo: voice construction from existing recordings • Voice for US film critic Roger Ebert • Loss of vocal function due to cancer • Pre-existing recordings (DVD commentaries) used by our spinout Cereproc to build a conventional unit-selection synthesiser • Huge media coverage • Example: • Oprah Winfrey show: http://www.youtube.com/watch?v=hMyxgSLESz8

  11. Demo: reconstruction of voices which are already disordered

  12. Demo: reconstruction of voices which are already disordered • Original disordered speech • Reconstructed synthetic speech
