Named-Entity-Recognition (NER) is one of the major tasks under Natural Language Processing, which is widely used in the fields of Computer Science and Computational Linguistics. However, the amount of prior research done on NER for Sinhala is very minimal. In this paper, we present data-driven techniques to detect Named Entities in Sinhala text, with the use of Conditional Random Fields (CRF) and Maximum Entropy (ME) statistical modeling methods. Results obtained from experiments indicate that CRF, which provided the highest accuracy for the same task for other languages outperforms ME in Sinhala NER as well. Furthermore, we identify different linguistic features such as orthographic word level and contextual information that are effective with both CRF and ME Algorithms.

Pharmacy management system for udupila pharmacy
(Department of Computer Science and Engineering, University of Moratuwa., 2015-10) Manamini, SAPM; Pemasiri, A; Bandara, M; Meedeniya, D; Perera, I
There are many pharmacy management systems available in the market with different sets of capabilities. This project aims to improve the functionality and features of such systems, and ease the functioning within a pharmacy. The proposed system addresses the problems from user, administrator, and super user perspectives. This paper describes the importance of the final product, compared to the existing pharmacy management systems available in the market. In addition, this report includes the system design, important implementations, testing procedures, and implementing strategies used for developing the final product.
