In this paper, we propose a system to collect human behavior in detail with higher-level tags such as attitude, accompanying-person, expenditure, tasks and so on. The system makes it possible to construct database to model higher-level human behaviors that are utilized in context-aware services. The system has two input methods, i.e., on-the-fly by a smart phone and post-processing by a PC browser...
This paper presents an end-to-end framework to manage user-centric services through daily events. In contrast to existing service discovery, selection and composition approaches, the proposed framework addresses the management issue from a new perspective by firstly learning end-user's intent through daily events, while recommending relevant functionalities to the user; and then enabling the user...
Network evolution is a hot research topic especially when social networking has become an important Web application. The access histories of Web users which contain the users traces' on a social network have not been considered useful data. However, they may reveal more about the network's connectedness if the history's time-sensitive characteristic is analyzed and studied. In this paper, we model...
A large number of online databases are hidden behind form-like interfaces which allow users to execute search queries by specifying selection conditions in the interface. Most of these interfaces return restricted answers (e.g., only top-k of the selected tuples), while many of them also accompany each answer with the COUNT of the selected tuples. In this paper, we propose techniques which leverage...
There is a huge wealth of sequence data available, for example, customer purchase histories, program execution traces, DNA, and protein sequences. Analyzing this wealth of data to mine important knowledge is certainly a worthwhile goal. In this paper, as a step forward to analyzing patterns in sequences, we introduce the problem of mining closed repetitive gapped subsequences and propose efficient...
Historians work with complex spatio-temporal data to create narrative accounts of historical developments. Historical sources are complex and diverse. They are often incomplete and contradictory and are drawn from many disciplines. The historian has the task of analyzing all the available evidence before synthesizing and re-presenting the data to create and interpret narratives which might account...
Today's mobile devices have inherited many of the characteristics of desktop computing -- including the assumptions that the user's full attention and dexterity can be focused on the interface. Unfortunately, on-the-go users are impaired by their mobility and often find desktop-style Windows Icon Menu and Pointer (WIMP) interfaces difficult, if not impossible, to use while performing their primary...
A honeypot is a type of information system that is used to obtain information on intruders in a network. When a honeypot is deployed in front of a firewall, it can serve as an early warning system. When deployed behind the firewall, it can serve as part of a defense-in-depth system and can be used to detect attackers who bypass the firewall and the intrusion detection system (IDS) or threats from...
We are deeply indebted to the members of ISI Software Division who developed the basic technology and approach for our effort. We especially wish to acknowledge the contributions of our colleagues, Dave Dyer and Matt Morgenstern, to the conceptualization and design of the system.
