Introduction

In the current information era, data processing documents has become a crucial task, with the volume of data collected and stored in the database increasing rapidly. This data can come from various sources, such as financial applications, Enterprise Resource Management (ERM), and Customer Relationship Management (CRM). To support better decision making, it is essential to apply data mining methods. This study explores the use of two clustering methods, Support Vector Clustering (SVC) and K-Medoids, to group documents.

The Importance of Clustering in Data Analysis

Clustering is a technique that allows large datasets to be grouped into categories or clusters that are relevant to the analysis. This makes it easier to analyze and interpret information. By using the SVC and K-Medoids algorithms, this study aims to identify the strengths and weaknesses of each algorithm in grouping documents.

Background of the Study

The study was conducted using the RapidMiner software to measure the execution time of the two algorithms. The results showed that SVC required an execution time of approximately 11:21 minutes, while K-Medoids only required approximately 3:21 minutes. This time difference indicates that K-Medoids is more efficient in terms of processing speed compared to SVC.

Analysis of the Support Vector Clustering (SVC) Algorithm

SVC is a clustering method based on the principle of Support Vector Machine (SVM). In the context of clustering, SVC utilizes a hyperplane to separate data into clusters. The advantages of SVC lie in its ability to handle data with non-linear constraints and group data with complex shapes. However, the complexity of calculations in SVC causes a longer execution time compared to other algorithms such as K-Medoids.

SVC can also produce clusters that are more defined and clearly separated. This makes it the right choice for data that has a complicated pattern or distribution. However, the selection of the right parameters in SVC is very important to get optimal results.

Analysis of the K-Medoids Algorithm

On the other hand, K-Medoids is a simpler and more efficient clustering algorithm. This algorithm selects the actual cluster center from data (medoids) rather than using an average as in K-Means. The advantages of K-Medoids include its ability to handle outliers better because medoid is more resistant to extreme values in data.

K-Medoids tend to be faster in processing and easier to implement on larger datasets. Although K-Medoids has limitations in determining the correct number of clusters, which can be a challenge in complex data analysis.

Comparison of SVC and K-Medoids

In the comparison between SVC and K-Medoids, each algorithm has its strengths and weaknesses that need to be considered according to the needs of the analysis. SVC is superior in terms of grouping complex and non-linear data, while K-Medoids is more efficient in terms of execution time, especially for large datasets and has outliers.

Conclusion

The selection of the right clustering method will be very dependent on the characteristics of data and objectives of the analysis. Therefore, it is essential for researchers and practitioners to understand the strengths and weaknesses of each algorithm in order to choose the most appropriate strategy for their needs in processing document data.

Recommendations

Based on the findings of this study, the following recommendations can be made:

SVC is recommended for data with complex patterns or distributions.
K-Medoids is recommended for large datasets with outliers.
The selection of the right clustering method should be based on the characteristics of the data and the objectives of the analysis.

Future Research Directions

Future research can focus on the following areas:

Developing new clustering algorithms that can handle complex data.
Improving the efficiency of existing clustering algorithms.
Applying clustering algorithms to real-world problems.

Limitations of the Study

This study has several limitations, including:

The study only compared two clustering algorithms.
The study only used a small dataset.
The study did not consider other clustering algorithms.

Conclusion

In conclusion, this study provides a comparative analysis of the Support Vector Clustering (SVC) and K-Medoids algorithm in the document cluster. The study found that SVC is superior in terms of grouping complex and non-linear data, while K-Medoids is more efficient in terms of execution time, especially for large datasets and has outliers. The selection of the right clustering method will be very dependent on the characteristics of data and objectives of the analysis.
