Automated Texting Services for Low-Resource Languages

Following our class period with Robert Munro, I found myself browsing through his Twitter and found an article describing his PhD topic in an August 9th Tweet. Within the article, he elaborates on some of the concepts discussed in class; as he explains, so many of the 5,000+ languages of the world are being written for the first time ever with the proliferation of mobile telephony, but the technology to process these languages cannot keep up. Compounding the problem, these phone users are of varied literacy levels, making for spelling inconsistencies among users. However, he concludes that automated information systems can pull out words that are least likely to vary in spelling (ie people, places, organizations) and examine subword variation by identifying affixes within words as well as accounting for phonological or orthographic variation (ie recognize vs. recognise). The article goes on to provide more technical prescriptions for automated text response services, and he even links to another article in a separate Tweet, which describes Powerset, a natural language search system that ultimately failed, but utilized a few valuable processes.

Ultimately, Dr. Munro implies that the capacity for automated text services in “low-resource languages” is well within reach, particularly because the messages are generally just one to two sentences. Because spelling variations are predictable, they can be modeled, and hopefully reliably answered by automated systems. However, the use of these systems will not be realized until they become more reliable and efficient than human responders, which, as he explained in class, can be extremely effective.


Mobile Banking: A Brief Overview

ImageOne of the most promising technological tools in the developing world is the mobile phone. Although there is still a significant difference in levels of mobile phone access and mobile phone usage, banking and money transfer has emerged as an area in which mobile phone technology can be useful and effective. This article gives a brief overview of the extent to which mobile banking has become a widely used technology. While in Eurpoe and North America, online banking is the norm, mobile banking is gaining more and more users in Asia, Africa, the Middle East and Latin America, where people do not have as easy access to computers. While we generally talk about developing countries benefitting from The Leapfrog Effect, it seems like in this case, developing countries have leaped right over online banking and found a solution more fitting to their needs. According to a Swedish industry research firm, mobile banking is expected to reach 894 million users by 2015. That would be a sixteenfold increase from 55 million users in 2009. Many companies in the developing world are looking to be the first to invest in mobile banking technology, and this field could perhaps become a booming global industry.
