Abstract

Clustering is one of the important part in web usage miningfor the purpose of segmenting visitors. This action is very important for web personalization orweb modification. In this paper, we perform clustering of the web visitors using a combination of methods of hierarchical and non-hierarchical clustering toward web log data. Hierarchical clustering method used to determine the number of clusters, and non-hierarchical clustering method is used in forming clusters. The stages of cluster analysis are preceded by pre-processing the data and factor analysis. With this approach, the owner of the web is more effective at finding access patterns of web visitors and can have new knowledge about visitors segmentation. From the test applied on ITSs web log data, 6 clusters of web visitors are resulted. Among the 6 cluster, cluster 3 has the biggest number of members. This information can be useful for web management to pay attention on members behavioral patterns of the 3rd clusters either to make personalization or modification on the web. The test results show the feasibility and efficiency of application of this method.

Abstract

Saat ini, konsep data mining semakin dikenal sebagai tools penting dalam manajemen informasi karena jumlah informasi yang semakin besar jumlahnya. Salah satu teknik yang dikenal dalam data mining adalah clustering,  berupa proses pengelompokan sejumlah data atau objek ke dalam cluster (group) sehingga setiap dalam cluster tersebut akan berisi data yang semirip mungkin dan berbeda dengan objek dalam cluster yang lainnya. Clustering memiliki dua metode, yaitu partisi dan hierarki. Dua metode ini memiliki kelebihan dan kekurangan masing-masing, dan dengan menggabungkan keduanya dapat diperoleh hasil cluster yang lebih baik. Dari hasil cluster dengan menggunakan data problem Kerja Praktek Jurusan Teknik Industri ITS, maka diperoleh hasil bahwa gabungan metode Single Linkage Clustering dan K-means memberikan hasil cluster yang lebih baik dengan parameter uji cluster variance dan metode silhouette coefisien.
