Sinhalese Text Entry Research by Shyam Reyal, University of St. Andrews

More info

The Sinhalese language (which falls into the family of Indo-Aryan languages) is spoken, read and written by over 22 million users worldwide (and by almost all the citizens of Sri Lanka). The language itself is very rich and complex – with over 60 base characters + 13 vowel variations for each, and also in terms of contextual phrases and idioms, which are much more diverse than Western languages. Nevertheless, very little work has been done in terms of creating efficient, user friendly text entry mechanisms for Sinhalese, in both computers and mobile devices. As present, despite attempts to standardize input methods, no such single main-stream popular method of text entry has surfaced. Continue reading

Seminar by Leo Liberti on “Symmetry in Mathematical Programming”, 19th Nov, 11am

Symmetry in Mathematical Programming

Abstract: When solving Mathematical Programming (MP) problems (be they linear or nonlinear, continuous or mixed-integer) using Branch-and-Bound (BB), the presence of symmetries of the solution set results in BB taking longer than strictly needed, due to the symmetries induced on the BB tree. I shall illustrate a class of “symmetry breaking” methods based on reformulating the symmetric MPs so that some of the symmetric optima become infeasible. I shall show how to automatically detect MP formulation symmetries by reducing MP to graphs, and how to automatically generate reformulated MPs with (hopefully) fewer symmetric optima. Although computational tests show that reformulations may not always succeed in making BB terminate faster, they can be applied very efficiently – so they can be considered an efficient “pre-solving step” to running BB.

We were privileged today to hear three lectures from Monty Widenius, main author of the MySQL database system.   His main focus was on entrepreneurship and being an entrepreneur while giving away source code on an open source basis.

Three staff members from St Andrews are pictured with Monty before the first lecture, in St Salvator’s quad at the University of St Andrews.

Title: Rich Speech Transcription for Spoken Document Processing

Abstract:
As storage costs drop and bandwidth increases, there has been rapid growth of spoken information available via the web or in online archives — including radio and TV broadcasts, oral histories, legislative proceedings, call center recordings, etc. — raising problems of document retrieval, information extraction, summarization and translation for spoken language. While there is a long tradition of research in these technologies for text, new challenges arise when moving from written to spoken language. In this talk, we look at differences between speech and text, and how we can leverage the information in the speech signal beyond the words to provide a rich, automatically generated transcript that better serves language processing applications. In particular, we look at how prosodic cues can be used to recognize segmentation, emphasis and intent in spoken language, and how this information can impact tasks such as topic detection, information extraction, translation, and social group analysis.
