| Abstract | Web Usage Mining is a research area that manipulates users' click stream data in order to identify interesting traversal patterns of visitors accessing the website. As the clickstream data is expanding over the time; the process of discovering users' frequent sequential pattern becomes a challenge due to the very low support distribution among the itemsets. By applying a Frequent Pattern Discovery technique, a sequence is considered as frequent if it occurs more than the minimum support (min sup) threshold value. The conventional method of assuming one min sup value is valid for all levels of k-sequence, may have an impact on the overall results or pattern generation. To overcome this issue, a personalized minimum support (P_minsup) threshold with user specified minimum items or (min_i) is introduced. The P_minsup is generated for each k-sequence by analyzing the overall support pattern distribution of the clickstream data; while the min_i value gives the user the flexibility to gain control on the number of pattern to be generated on the nextksequence by using the top min_i items. This approach is then applied in the SPADE Algorithm using vector array as an extension from the previous method of using relational database and pre-defined threshold. The result from this experiment demonstrates the performance of P_minsup with the complement of min_i value approach is effective based on the execution time in discovering frequent pattern in eachk-sequence. |
