Smart environments require to percept conditions of people. Current context-aware systems mainly model limited user situations, which constrains their coverage and effect in real world usage. This paper proposes an encyclopedic knowledge network to enable practical context inference in our daily life by: 1) expressing essential semantics of contextual concepts and relations into a well-informed relational network, and 2) exploiting relational semantics to infer various contexts simultaneously. The performance of the approach is validated in real challenging problems and compared with inference of human being.

Yang, Zi, Cai, Keke, Tang, Jie, Zhang, Li, Su, Zhong and Li, Juanzi (2011): Social context summarization. In: Proceedings of the 34th Annual International ACM SIGIR Conference on Research and Development in Information Retrieval 2011. pp. 255-264. Available online
We study a novel problem of social context summarization for Web documents. Traditional summarization research has focused on extracting informative sentences from standard documents. With the rapid growth of online social networks, abundant user generated content (e.g., comments) associated with the standard documents is available. Which parts in a document are social users really caring about? How can we generate summaries for standard documents by considering both the informativeness of sentences and interests of social users? This paper explores such an approach by modeling Web documents and social contexts into a unified framework. We propose a dual wing factor graph (DWFG) model, which utilizes the mutual reinforcement between Web documents and their associated social contexts to generate summaries. An efficient algorithm is designed to learn the proposed factor graph model. Experimental results on a Twitter data set validate the effectiveness of the proposed model. By leveraging the social context information, our approach

MobileAnalymator (Mobile Analysis Animator) is a visual analytic system designed to analyze geospatial-temporal data on mobile devices. The system is an Internet based application that allows analysts to work in flexile enviornments at anytime. Its client side is developed by Adobe Flash to animate and interact with data. The server side uses Java and MySQL to query, compute, and serve data. The analyst can run the analytical task from a tablet (or computer) with Internet connection. MobileAnalymator adopted spatial and temporal autocorrelations in the interface design and integrated tangible interaction in the navigation to support analysis process.

Zhang, Li, Gillies, Marco and Barnden, John (2008): EMMA: an automated intelligent actor in e-drama. In: Proceedings of the 2008 International Conference on Intelligent User Interfaces 2008. pp. 409-412. Available online
We report work on adding an improvisational AI actor and 3D emotional animation to an existing edrama program, a system for dramatic improvisation in simple virtual scenarios. The improvisational AI actor has an affect-detection component, aimed at detecting affective aspects of human-controlled characters' textual input. It also makes an appropriate response to stimulate the improvisation based on this affective understanding. A distinctive feature of our work is a focus on the metaphorical ways in which affect is conveyed. Moreover, we have also introduced how the detected affective states activate the animation engine to produce emotional gestures for human-controlled characters. Finally, we report user testing conducted for the AI actor. Our work contributes to the conference themes on affective user interfaces, natural language processing and emotionally believable gesture generation.

In this paper we study the problem of finding most topical named entities among all entities in a document, which we refer to as focused named entity recognition. We show that these focused named entities are useful for many natural language processing applications, such as document summarization, search result ranking, and entity detection and tracking. We propose a statistical model for focused named entity recognition by converting it into a classification problem. We then study the impact of various linguistic features and compare a number of classification algorithms. From experiments on an annotated Chinese news corpus, we demonstrate that the proposed method can achieve near human-level accuracy.

Large quantities of documents in the Internet and digital libraries are simply scanned and archived in image format, many of which are packed in PDF files. The word search tool provided by Adobe Reader/Acrobat does not work for these imaged documents. In this paper, we present a search engine to deal with this issue for imaged documents in PDF files. The experimental results show an encouraging performance.

The overwhelming success of the Web as a mechanism for facilitating information retrieval and for conducting business transactions has led to an increase in the deployment of complex enterprise applications. These applications typically run on Web Application Servers, which assume the burden of managing many tasks, such as concurrency, memory management, database access, etc., required by these applications. The performance of an Application Server depends heavily on appropriate configuration. Configuration is a difficult and error-prone task dueto the large number of configuration parameters and complex interactions between them. We formulate the problem of finding an optimal configuration for a given application as a black-box optimization problem. We propose a smart hill-climbing algorithm using ideas of importance sampling and Latin Hypercube Sampling (LHS). The algorithm is efficient in both searching and random sampling. It consists of estimating a local function, and then, hill-climbing in the steepest descent direction. The algorithm also learns from past searches and restarts in a smart and selective fashion using the idea of importance sampling. We have carried out extensive experiments with an on-line brokerage application running in a WebSphere environment. Empirical results demonstrate that our algorithm is more efficient than and superior to traditional heuristic methods.

Zhang, Li and Ardagna, Danilo (2004): SLA based profit optimization in web systems. In: Proceedings of the 2004 International Conference on the World Wide Web 2004. pp. 462-463. Available online
With the rapid growth of eBusiness, the Web services are becoming a commodity. To reduce the management cost for the IT infrastructure, companies often outsource their IT services to third party service providers. Large service centers have been setup to provide services to many customers by sharing the IT resources. This leads to the efficient use of resources and a reduction of the operating cost. The service provider and their customers often negotiate utility based Service Level Agreements (SLAs) to determine the cost and penalty based on the achieved performance level. The system is based on a centralized controller which can control the request volumes at various servers and the scheduling policy at each server. The controller can also decide to turn ON or OFF servers depending on the system load. This paper designs a resource allocation scheduler for such web environments so as to maximize the profits associated with multiple class SLAs.
