随着移动计算的发展,通过手持设备存取Web将越来越普遍。手持设备的限制和多样性要求同一Web页面具有不同的表现形式,因此需要对Web页面进行选择、拆分等自适应操作以满足手持设备能力的限制。为了提高自适应页面的质量,提出一个两阶段页面拆分算法。该算法在保证自适应页面正确性的基础上,提出量化评估函数以保证每个小页面的语义连贯性和最优的资源利用率,从而增加页面的可用性。该算法已应用于多个样本页面,结果表明拆分结果具有较好的可用性。
As mobile computing evolves, access to the web through handheld devices will become more commonplace. The limitations and diversity of handheld devices require different manifestations of the same Web page, so Web pages need to be adaptively adapted to meet the limitations of handheld device capabilities. In order to improve the quality of adaptive pages, a two-stage page splitting algorithm is proposed. On the basis of ensuring the correctness of the adaptive page, this algorithm proposes a quantitative evaluation function to ensure the semantic coherence and the optimal resource utilization of each small page so as to increase the usability of the page. The algorithm has been applied to multiple sample pages, the results show that the split results have better usability.
