Mobile devices can now handle a great deal of information thanks to the convergence of diverse functionalities. Mobile environments have already shown great potential in terms of providing customized service to users because they can record meaningful and private information continually for long periods of time. The research for understanding, searching and summarizing the everyday-life of human has received increasing attention in recent years due to the digital convergence. In this paper, we propose a mobile life browser, which visualizes and searches human's mobile life based on the contents and context of lifelog data. The mobile life browser is for searching the personal information effectively collected on his/her mobile device and for supporting the concept-based searching method by using concept networks and Bayesian networks. In the experiments, we collected the real mobile log data from three users for a month and visualized the mobile lives of the users with the mobile life browser developed. Some tests on searching tasks confirmed that the result using the proposed concept-based searching method is promising.

Lifelog浏览器，用于可视化和搜索移动日常生活

由于各种功能的融合，移动设备现在可以处理大量信息。在为用户提供定制服务方面，移动环境已经显示出巨大的潜力，因为它们可以长时间连续记录有意义的私人信息。由于数字融合，近年来关于理解，搜索和概括人类日常生活的研究受到越来越多的关注。在本文中，我们提出了一种移动生活浏览器，该浏览器根据生活日志数据的内容和上下文可视化并搜索人类的移动生活。移动生活浏览器用于搜索有效收集在他/她的移动设备上的个人信息，并通过使用概念网络和贝叶斯网络来支持基于概念的搜索方法。在实验中，我们从三个用户那里收集了一个月的真实移动日志数据，并使用开发的移动生活浏览器可视化了用户的移动生活。对搜索任务的一些测试证实，使用提出的基于概念的搜索方法的结果很有希望。
