This talk is in the field of Computational Linguistics which analyzes the bit patterns of human language. It is at the intersection of Computer Science and Linguistics and is closely related to Information Theory. There are 3 kinds of language: spoken (sequences of phonemes), written (sequences of graphical characters), and text (sequences of characters encoded for computers). This talk will focus on the languages of the world, especially in the form of text. Say you have some text such as a web page or email in a language you do not recognize. Of the many thousands of languages which one is it? Identifying the language may allow you to forward it to someone who knows the language or to the appropriate automatic translator. Difficulties include: a) some text will contain few words or may be contain more than one language, b) the ratio of linguistic information to web formatting may be quite small making everything look like English, and c) speed requirements may limit you to extremely simple algorithms (if you wish to perform this task on billions or trillions of web pages or real-time on rapidly streaming text) . This talk will provide a brief introduction to the world’s scripts (alphabets, etc.) and the languages encoded using those scripts and how languages can be identified. After Alan retired from the government he became Chief Knowledge Engineer at Northrop Grumman Information Systems using parallel computing to make sense of vast data sets including text, images, audio, video, network traffic, network security and financial transactions. He retired to England in 2017. You will need the Zoom client installed on your computer, tablet or phone. Short video on using Zoom here:
