- 303 abstract "We report on a series of user research of when, where, how and, why people used the web via mobile devices. The paper is primarily based on contextual interview with forty-seven participants from six cities between 2004 and 2007, complementing a phone log data analysis of five hundred and seventy-seven panelists from three countries in 2007. In this paper, we identified four key contextual factors and proposed a framework of mobile web activities. The framework consists of four categories of user activities: information seeking, communication, transaction, and personal space extension. The previous studies on the conventional web presented the first three items but not the last one: personal space extension, which includes the activities that people use the mobile web to manage contents mainly for personal access, therefore extend personal digital space.".

- 310 abstract "In many networked data, such as social networks and paper co-authorship networks, individuals form various communities through interactions. Very often, these communities evolve continuously with time, due to, for example, the change of a person's social status or the change of an author's research interest. Discovering communities and analyzing their evolutions are important research problems. Traditionally, these two problems are usually solved separately, i.e., through a two-stage approach where in the first stage communities are extracted for each timestep and in the second stage, the extracted communities of different timesteps are compared to study their evolutions. We argue that such a two-stage approach is inappropriate in many applications where data are often noisy and algorithms are not necessarily robust. In contrast, in this paper we propose a novel framework, FacetNet, for analyzing communities and their evolutions through a unified process. This framework will discover communities that both fit well with current observed networked data and evolve smoothly over time. We present our framework in the form of non-negative matrix factorization, while at the same time we also provide justification to our formulation from the information theory and probabilistic model points of view. To solve our formulation, we provide an iterative algorithm that is guaranteed to converge to an optimal solution. The algorithm has provable low time complexity. We use extensive experimental studies, both on synthetic datasets and on real datasets, to demonstrate that our method gives more reasonable communities and provides insights that are not directly obtainable from traditional methods.".

- 311 sameAs 311.
- 311 abstract "It is notoriously difficult to program a solid web application. Besides addressing web interactions, state maintenance, and whimsical user navigation behaviors, programmers must also avoid a minefield of security vulnerabilities. The problem is twofold. First, we lack a clear understanding of the new computation model underlying web applications. Second, we lack proper abstractions for hiding common and subtle coding details that are orthogonal to the business functionalities of specific web applications. This paper addresses both issues. First, we present a language BASS for declarative server-side scripting. BASS allows programmers to work in an ideal world, using new abstractions to tackle common but problematic aspects of web programming. The meta properties of BASS provide useful security guarantees. Second, we present a language MOSS reflecting realistic web programming concepts and scenarios, thus articulating the computation model behind web programming. Finally, we present a translation from BASS to MOSS, demonstrating how the ideal programming model and security guarantees of BASS can be implemented in practice.".
