4. Introducton
Afan Oromo is a major indigenous African language that is widely
spoken and used in most parts of Ethiopia, as well as some
neighboring countries.
It is spoken by 40% of Ethiopians and also used as a lingua franca
among other groups who interact with the Oromo people.
Stance detection is a technique used to determine whether the
author of a text supports, opposes, or has no opinion about a
specific topic.
Detecting stance is important in social media, particularly for
analyzing public opinions on political and social issues

5. Cont.…
Stance detection plays an important role in analyzing public
opinion on controversial issues such as abortion, climate change,
feminism, referendums and elections.
Stance classification is a field of natural language processing that
has many uses.
It can recognize whether a community supports or opposes a
particular viewpoint related to religious and political topics
automatically.
It is also useful in developing recommendation and market
forecasting systems.

6. Statement of the problem
Internet have led to an increase in social media usage, allowing
people to express their perspectives and engage in idea exchange.
Many problems faced in the country such as displacement of
people due to civil war, unemployment, and high cost of living.
 These problems arise because the government does not
understand people's interests or viewpoints towards policies and
public interests.
Most research on analyzing people's attitudes on social media
regarding a particular topic has been done in English and
European languages
This is because it is hard to apply the existing models and
approaches to other languages like Oromic.

8. Based on the above statement of problem, the research
questions are:
 Which Machine learning algorithm works best for
Afan Oromo stance classification?
 What is the impact of normalization on Afan Oromo
stance classification?
 To what extent the model performs in classify Afan
Oromo stance?
Research Questions

9. Objectives
General Objective
The main objective of this study is to develop an Oromic
stance classification Model using Machine learning
techniques.
Specific Objectives
 To achieve the main goal of the above general objective
the study will focus on several specific objectives.

10. Cont.…
 To review relevant previous studies to find suitable methods and
techniques.
 Collect and prepare data,
 Build and test different algorithms for classification,
 To develop an appropriate machine learning model for the
proposed work.
 To compare and evaluate the generated classification model using
different metrics.

11. Scope and limitation
Scope
Uses machine learning to detect the political stance in
Oromic language text
The researchers has going to collect posts and comments
from a Facebook page of a political party, annotated them
into two classes (in favor or against)

12. Limitation
The research has some limitations because there are not many other
studies to compare it with when detecting political opinions in
Oromic language text.
Can not determining who wrote a text and why they
have a certain stance,
Can not verifying if the person expressing their opinion
is legitimate.
Cont.…

13. Significance of the study
Used to measure public opinion towards events or entities.
Helps to understand the level of support related to social,
religious, and political topics by analyzing people's attitudes
and opinions towards them.
Used to identify people's political affiliations based on their
online posts during elections.
Used to detect whether someone supports or opposes
something based on their online posts

16. Methodology
Research Design
 The reasearcher use DSR process to do the research.
 DSR has the following step.
 Problem identification
 Define objectives for a solution
 Design and development
 Demonstration
 Evaluation

17. Data preparation
 Data is collect from social media using a tool called
Facepager,
 The data is processed to remove unnecessary characters, split
sentences into words, remove punctuation and convert words
to their root form .

18. Performance Evaluation
 The accuracy of a classification model is going to
evaluate using four main metrics, those metrics are the
following:
 Accuracy,
 precision,
 Recall and
 F1-score.
