Abstract

This paper presents designing a rule based Afan Oromo Disambiguator. The ultimate aim of this work is to develop a model that identifies the senses of the words. Hence; a word may have multiple senses, the problem is to find out which particular sense is appropriate in a given context. To this end, a rule based approach was used which is designed manually a set of rules. Some ambiguous words were collected from the Oromo society and these words are the most frequently used in the society. Due to under the resource of the language, the work was used 15 natural ambiguous words for the sake of the test. The results of the work were shown that in Afan Oromo language, an ambiguous word have 2 to the n senses (where n unlimited senses; as the number of contexts increased).

Summary

Introduction

The disambiguation is the most challenging at all levels of the natural languages. The ultimate aim of this work was to develop a set of rules that identified the senses of the words. The modifiers and contextual information were the basis of the linguistic properties of Afan Oromo word sense. The modifier of the ambiguous word is used in order to get the semantic clues of the particular sense in which the ambiguous word is used To achieve this we analysed the structure of Afan Oromo sentence formation with respect to modifying patterns to develop the rule. The writing system of Qubee (Latin-based alphabet) has been started since 1842 [4] It is one of the major African languages that is widely spoken and used in most parts of Ethiopia and some parts of other neighbour countries like Kenya, Tanzania, Djibouti, Sudan and Somalia. According to Afan Oromo structure, the Noun and Verb always appear before the word they modify [8]
