摘要(英) |
In recent years, on-line shopping is becoming popular and creating larger sales scale because of the rapid development of Internet technologies. According to an estimation conducted by the Institute for Information Industry in 2016, Taiwan′s e-commerce in 2017 is expected to reach NT$ 1,255 billion (US$ 41.5 billion), of which B2C business platform will be accounted for NT$ 687.5 billion (US$ 22.6 billion), more than half of the amount forecasted. Multiple surveys in 2016 showed that the e-commerce corporation PCHome Online was ranked first in terms of the online sales revenue and the number of commodity item.
In this paper we decipher the development and application of memory card products by using the data mining technology to analyze the data of PCHome Online commodities. First we apply the data preprocessing technique on the raw data to generate data sets. Next we apply the clustering technique of the exploratory data analysis on the data sets. The result suggests a better K-Means value when the data sets are divided into four groups. Thus we divide the memory card market into four corresponding segments: Light User, Moderate User, Power User and High-End User.
Since the introduction of commercial memory cards in 1994, more and more manufacturers have joined the memory card industry to provide diversified products to meet consumers’ requirement for storage capacity and speed. The recent development of embedded memory and cloud storage has, however, posed a threat against the current memory card market. A survey found that the capacity of embedded memory in 2017 has evolved to be more than 128G, and that the cloud storage has gradually gained acceptance and recognition from users.
On reviewing the trend of memory card developments, this paper estimates the Light User market segment will diminish as the obsolescent products reach their end-of-life, while the Moderate User and Power User segments will be affected by the applications of embedded memory and cloud storage. As for the High-End User segment, it will continue to thrive as the demands for storing high-resolution images and videos continue to grow. |
