Unfortunately, most of existing on-demand scheduling algorithms did not consider the time constraints associated with web requests. This paper proposes a novel scheduling algorithm, called Slack Inverse Number of requests (SIN), that takes into account the urgency and productivity of serving pending requests. Trace-driven experiments demonstrate that SIN significantly out performs existing algorithms over a wide range of workloads.","PeriodicalId":409891,"journal":{"name":"WWW Alt.

We believe that tutors, starting from a simple generic curriculum, and assuming that they have the proper tools, can much easier create curriculum alternatives as immediate response to the current learning situation. In this paper we present a tool that provides a flexible environment for tutors allowing them to customize, and develop the curriculum on-the-fly. However, since individual tutoring is quite expensive we shortly discuss possibilities for enabling automatic adjustment of course curriculum to learners' needs by combining on-the-fly curriculum alternatives created by tutors with well-known automatic course sequencing techniques.","PeriodicalId":409891,"journal":{"name":"WWW Alt.

Objects that support travel and mobility are not in an appropriate form for nonvisual interaction. Our goal is to enhance the mobility of visually impaired Web travellers by annotating pages with a travel ontology that aims to encapsulate rich structural and navigational knowledge. We propose a semi-automated tool 'Dante' which aims to analyse Web pages to extract travel objects, discover their roles, annotate them with a travel ontology and transform pages based on the annotations to enhance the provided mobility support. This poster introduces the travel ontology and presents how Web pages are annotated with this ontology to guide the transformations.","PeriodicalId":409891,"journal":{"name":"WWW Alt.

Until now two main types of approaches have been proposed for this task: content- and context-based methods. Both of them assume fixed content and characteristics of web documents without considering their dynamic nature. However the volatility of information published on the Internet argue for the implementation of more time-aware techniques. This paper proposes a new approach towards automatic web page description, which extends the concept of a web page by the temporal dimension. Our method provides a broader view on web document summarization and can complement the existing techniques.","PeriodicalId":409891,"journal":{"name":"WWW Alt.

Firework Query Model solves this problem by Peer Clustering and routes the query message more intelligently. However, it still contains drawbacks like query flooding inside clusters. The condition can be improved if the query message can send directly to the query destination, as the message does not need to send hop by hop. This can be achieved by ranking. By ranking, the network can know the destination and the information quality shared by each peer. We introduce distributed ranking in this paper. We give background of FQM, outline of the proposed method, and conduct a series of experiments that demonstrate the significant reduction of query flooding in a P2P network.","PeriodicalId":409891,"journal":{"name":"WWW Alt.

During the learning progress it also provides assessments on students' learning performances and gives suggestions to guide them in further learning.

ECL is one outcome of a pan-Canadian project called eduSource Canada to build an open network of interoperable digital repositories. The design goal was to achieve a highly flexible, easy-to-use, and platform independent communication layer protocol that allows new and existing repositories to communicate and share resources across a network. ECL conforms to IMS Digital Repository Interoperability (DRI) specifications and supports four main functions: search/expose, submit/store, gather/expose and request/deliver. The ECL protocol builds on the latest standards and is flexible with respect to metadata schemas and repository contents. To support easy adoption of the protocol we provide middleware components for connecting existing systems. The ECL is currently used in the eduSource network, and we have begun work bridging with other interoperable initiatives such as Open Knowledge Initiative (OKI). Based on our experience, ECL is truly flexible and easy to use.","PeriodicalId":409891,"journal":{"name":"WWW Alt.
