Web information gathering processes for gold and silver price information

This paper presents a research on product-specific web information gathering concept that intends to improve web searching through conventional search engines.Search engines are useful for searching general information; however, the results are not always accurate because they return the results based on key-words occurrences, but not accurateness.Further, users must filter and organize the information accordingly to make the information meaningful.Users must also visit multiple websites independently to check whether the information is relevant.These processes are tedious and very time consuming especially for users who search for specific products information Hence, we propose a web information gathering model that aims to provide a standard for developing product-specific web searching tools. It was applied in a mobile application called Gold-Trader. The mobile application provides gold and silver prices information to individual or personal traders.It can help individual or personal traders to monitor and compare gold and silver prices from multiple websites without the needs to visit them individually

An overview to pre-fetching techniques for content caching of mobile applications

The Internet and web have been the main resource for various types of information for majority of people in the world since a decade ago. With the emerging of smartphone technology, the web content is also available for mobile users that connect to the Internet through cellular network. Although mobile users are able to access content from the web; nevertheless, they always experience long access latency due to the speed of the network. Many research and developments have been implemented to help users to access content faster when using mobile devices with cellular network. Caching is one of them; a commonly used method for storing recently-accessed contents so that they can be used in the future. Content caching (CC) can reduce latency, which in return guarantees faster access to the content. Recently, there is a growing interest among researchers and developers in studying a more proactive technique to improve CC called pre-fetching (PF). PF is a method that caches selected content before it is actually needed. By embedding PF in CC, it is believed that latency could be reduced significantly. By looking at this promising approach, this paper introduces the PF techniques that could be suitable for CC in mobile environment. The paper aims to assist researchers by providing a better understanding on the existing PF techniques so that improvements can be proposed where possible
