TL;DR: The proposed method can automatically generate the context and does not need any prior knowledge such as ontology or a hierarchical knowledge base and is used on some applications such as trend analysis, faceted exploration, and query suggestion.

TL;DR: This chapter proposes a novel context modeling approach based on services, where context information is linked according to explicit high-level constraints, and uses semantic Web technologies by specifying RDF profiles and experimenting on their usage on several platforms to validate the proposal.
Abstract: Currently, multimedia documents can be accessed at anytime and anywhere with a wide variety of mobile devices, such as laptops, smartphones, and tablets. Obviously, platform heterogeneity, users' preferences, and context variations require document adaptation according to execution constraints. For example, audio contents may not be played while a user is participating in a meeting. Current context modeling languages do not handle such real life user constraints. These languages generally list multiple information values that are interpreted by adaptation processes in order to deduce implicitly such high-level constraints. In this chapter, the authors overcome this limitation by proposing a novel context modeling approach based on services, where context information is linked according to explicit high-level constraints. In order to validate the proposal, the authors have used semantic Web technologies by specifying RDF profiles and experimenting on their usage on several platforms.

TL;DR: This paper designed and developed a technology enhanced learning platform supporting architecture professionals' study at city excursions and other mobile tasks and employs the MPEG-7 and MPEG-21 multimedia metadata standards.
Abstract: Mobile technology enhanced learning pertains to the delivery of multimedia learning resource onto mobile end devices such as cell phones and PDAs. It also aims at supporting personalized adaptive learning in a community context. This paper presents a novel approach to supporting both aspects. The community aware content adaptation employs the MPEG-7 and MPEG-21 multimedia metadata standards to present the best possible information to mobile end devices. Meanwhile, interest patterns are derived from a community aware context analysis. We designed and developed a technology enhanced learning platform supporting architecture professionals' study at city excursions and other mobile tasks.

TL;DR: The MPEG-21 Dynamic Content Adaptation Framework, acronym DCAF, is presented, which uses a fusion of Genetic Algorithms and Strength Pareto Optimality to adapt content in order to suit the usage environment.
Abstract: Universal Multimedia Access aims at providing a gratifying end user-experience by either adapting the content, be it static or dynamic, to suit the usage environment or adapting the usage environment, be it client- or server-centric, to suit content. This paper presents our MPEG-21 Dynamic Content Adaptation Framework, acronym DCAF, which uses a fusion of Genetic Algorithms and Strength Pareto Optimality to adapt content in order to suit the usage environment.

TL;DR: A new approach to planning in STRIPS-like domains based on constructing and analyzing a compact structure the authors call a Planning Graph is introduced, and a new planner, Graphplan, is described that uses this paradigm.
Abstract: We introduce a new approach to planning in STRIPS-like domains based on constructing and analyzing a compact structure we call a Planning Graph. We describe a new planner, Graphplan, that uses this paradigm. Graphplan always returns a shortest-possible partial-order plan, or states that no valid plan exists. We provide empirical evidence in favor of this approach, showing that Graphplan outperforms the total-order planner, Prodigy, and the partial-order planner, UCPOP, on a variety of interesting natural and artificial planning problems. We also give empirical evidence that the plans produced by Graphplan are quite sensible. Since searches made by this approach are fundamentally different from the searches of other common planning methods, they provide a new perspective on the planning problem.

TL;DR: Graphplan as mentioned in this paper is a partial-order planner based on constructing and analyzing a compact structure called a planning graph, which can be used to find the shortest possible partial order plan or state that no valid plan exists.

TL;DR: PDDL2.1 as discussed by the authors is a modelling language capable of expressing temporal and numeric properties of planning domains and has been used in the International Planning Competitions (IPC) since 1998.
Abstract: In recent years research in the planning community has moved increasingly towards application of planners to realistic problems involving both time and many types of resources. For example, interest in planning demonstrated by the space research community has inspired work in observation scheduling, planetary rover exploration and spacecraft control domains. Other temporal and resource-intensive domains including logistics planning, plant control and manufacturing have also helped to focus the community on the modelling and reasoning issues that must be confronted to make planning technology meet the challenges of application. The International Planning Competitions have acted as an important motivating force behind the progress that has been made in planning since 1998. The third competition (held in 2002) set the planning community the challenge of handling time and numeric resources. This necessitated the development of a modelling language capable of expressing temporal and numeric properties of planning domains. In this paper we describe the language, PDDL2.1, that was used in the competition. We describe the syntax of the language, its formal semantics and the validation of concurrent plans. We observe that PDDL2.1 has considerable modelling power -- exceeding the capabilities of current planning technology -- and presents a number of important challenges to the research community.
