Abstract:
With advances in technology, mobile handheld devices - such as cellular phones and PDAs - have become very popular. In many real-life situations, users want to find “interrelated” information or Web pages. However, the mobile handheld devices have relatively limited resources. Hence, a navigation summary is in demand. We develop a top-k adaptable search-tree algorithm from the optimal Web structuring model that can be used to provide Web search recommendations for mobile handheld devices. In order to find “optimal” solution, a new ranking measure to calculate the Web arc weights is proposed. Such a measure can be used as an alternative to, or used in conjunction with, conventional measures -- such as PageRank, tf-idf, HITS, and anchor text?for determining the relevance of Web objects. Moreover, besides optimality, the solution that we derived from the optimal Web structuring model guarantees a robust range for changes in the Web objects so that these Web objects and their corresponding hyperlinks can be easily updated. Furthermore, due to the nature of the Web, relevant information may span over various page. To this end, our structural Web navigation can cover information from more than a single page so that this information can be effectively shown on mobile handheld devices for mobile Web navigation. Our experimental results on real Websites show the effectiveness of our proposed Web search mechanism.
