A decentralised approach to information retrieval for a developing country like Bangladesh
(BRAC University, 2007) Ali, Hammad; Haque, Nafid
In this paper, we talk about a decentralised information retrieval system which would be suitable for the developing countries that face the problem of limited bandwidth. In this paper we came up with an implementation that uses the existing technology in a novel manner to meet the specific needs of users in such countries. We considered the infrastructural limitations of a developing country like Bangladesh and thus the solution presented here performs just as well in similar situations anywhere else in the world. Our work has been tested for the Bangla language and the same procedure can be applied easily for any other language in any part of the world where there is need for such a system. We had to pick and choose from a set of software packages for one that would best serve our needs. We also had to take into consideration user convenience, for which we had to keep in mind the diverse demographics of people that might have need of such a system. Finally, we came up with the system with all the desired features.
Design of head-driven phrase structure grammar for Bangla
(BRAC University, 2006-12) Ayesha Binte Mosaddeque; Ali, M. Hammad; Haque, Nafid; Khan, Mumit
A considerable amount of work is being done in recent years in the arena of Computational Linguistics. However, little has been done in developing a generic computational grammar for the Bangla language that could be used for advanced language processing. Context Free Grammar (CFG) has been attempted for English, and it has been realized that this does not have the descriptive power required to model a natural language. The chief reason behind this is the large number of rules that are needed in order to capture the vast array of natural language phenomenon. Our target is to try and implement a Head-driven Phrase Structure Grammar (HPSG) for Bangla. We would like to find out a pattern behind the various phenomenon of the language and try to capture these in the form of generalizations for the different entities of the language. We would also like to explore the underlying patterns governing the successful unification of feature structures. Eventually, we want to end up with a small scale working implementation of a Bangla HPSG that can recognize and generate a set of representative sentences from the Bangla language, accurately capturing relevant linguistic phenomenon.
Infrastructure for Bangla information retrieval in context of ICT for development
(BRAC University, 2006) Haque, Nafid; Ali, M Hammad; Abduallah, Matin Saad
In this paper, we talk about developing a search engine and information retrieval system for Bangla. Current work done in this area assumes the use of a particular type of encoding or the availability of particular facilities for the user. We wanted to come up with an implementation that did not require any special features or optimizations in the user end, and would perform just as well in all situations. For this purpose, we picked two case studies to work on in our effort to finding a suitable solution to the problem. While working on these cases, we encountered several problems and had to find our way around these problems. We had to pick and choose from a set of software packages for the one that would best serve our needs. We also had to take into consideration user convenience in using our system, for which we had to keep in mind the diverse demographics of people that might have need for such a system. Finally, we came up with the system, with all the desired features. Some possible future developments also came into mind in the course of our work, which are also mentioned in this paper.
Localization birdging the digital divide
(BRAC University, 2007) Haque, Nafid
In this paper, a proposal has been given to make an equitable access of education and technology among the people of the underdeveloped and developing countries of the world. Here a concept called localization has been studied and the impacts that localization can bring in the daily life of a person is highlighted. The proposal highlights on the benefits of localization and how it can act as a bridge to reduce the digital divide. This paper proposes all the available and flexible methods that can be used to implement a localization project systematically. The paper also highlights how students can participate in these types of projects and can work for the welfare of the country and its people.
