Identification of Indonesian Spam SMS using Twitter-LDA Algorithm: A Comprehensive Approach

Introduction

In today's digital era, SMS Spam has become a significant problem for mobile users worldwide. Unwanted messages, such as advertising, fraud, and erotic services, often interfere with daily activities, causing frustration and inconvenience. To overcome this problem, researchers have developed various methods to identify SPAM SMS, including making black lists and classification of text. Among these methods, text classification has proven to be more efficient in detecting SPAM SMS. Therefore, research on the identification of SMS spam through text classification continues to develop to increase the accuracy of the detection system.

The Twitter-LDA Algorithm: A Novel Approach

One of the latest studies has developed a SPAM SMS identification system in Indonesian using the Twitter-LDA method. This method involves several comprehensive stages, ranging from preprocessing to SMS classification. The preprocessing process includes steps such as:

Case Folding: Converting all text to lowercase to reduce the dimensionality of the data.
Removal of Punctuation: Removing punctuation marks to prevent them from affecting the classification process.
Tokenisation: Breaking down the text into individual words or tokens.
Handling URLs and Telephone Numbers: Removing URLs and telephone numbers to prevent them from affecting the classification process.
Stemming: Reducing words to their base form to reduce the dimensionality of the data.
Filtering: Removing stop words and irrelevant words to improve the quality of the data.
Normalization: Normalizing the text data to improve the accuracy of the classification process.

After the preprocessing stage, modeling the topic is done using Twitter-LDA, where this method is able to identify the themes that appear in a collection of SMS texts.

Comparison of F-Score Results

In this study, researchers made a comparison of F-Score results between SMS classifications using models that apply filtering and/or normalization and models without filtering and/or normalization. The analysis shows that the model equipped with normalization produces a higher F-score, reaching 96.24%. This indicates the effectiveness of the normalization method in increasing the accuracy of the SPAM SMS classification.

Advantages of the Twitter-LDA Algorithm

Identification of SMS Spam using the text classification method, especially with Twitter-LDA, offers a number of advantages. First, this method does not only rely on blacklisted that may not always be the latest, but uses a context-based approach that is able to recognize patterns in text data. This is important because spam actors often change their message delivery techniques to avoid detection.

Second, the preprocessing stage is very crucial in improving the quality of data before making modeling. Processes such as filtering and normalization help clean the text of irrelevant elements, so the model can focus on more significant words in determining whether an SMS is included in the spam category or not.

Third, the use of F-Score as an evaluation metric provides a clearer picture of the balance between precision and recall in classification. The model that produces high F-score means having a good ability to identify SMS spam without producing much false positive, which can interfere with users.

Conclusion

The application of the Twitter-LDA algorithm in the identification of SPAM SMS not only helps users to avoid unwanted messages, but also contributes to the development of a more sophisticated spam detection system in the future. This research is one of the initial steps that promises in an effort to create a safer and more convenient communication environment for all mobile users.

Future Directions

Future research can focus on improving the accuracy of the Twitter-LDA algorithm by incorporating additional features, such as:

Using more advanced preprocessing techniques, such as named entity recognition and part-of-speech tagging.
Incorporating additional features, such as sentiment analysis and topic modeling.
Using more advanced machine learning algorithms, such as deep learning and ensemble methods.

By improving the accuracy of the Twitter-LDA algorithm, researchers can develop a more effective spam detection system that can help users avoid unwanted messages and create a safer and more convenient communication environment.
