Towards a Unified Framework for Media Capacity Characterization: Inferences from Critical Analysis of Media Capacity Theories, Buzzwords and Web History
As the Web enters its third decade of existence, I draw attention to the need to better understand the Web as a potential reference case for how an information system transforms through incremental innovations, with particular focus on the Webâs advancement as a communication media platform. As a necessary research step in this quest, I critically examine whether one can use existing media capacity theories and media-related buzzwords (such as rich media, multimedia, hypermedia, social media) to characterize Web innovations as media. I examine and clarify these buzzwordsâ origins, meanings, and relationship with media capacity theories. I also elucidate discrepancies between them. Via inductive reasoning, I synthesize three media capacity dimensions (sensibility support, interactivity support and logistical support) as potential framework for objective media characterization. Each dimension could metamorphize into individual theories or one theory (e.g., sensibility interactivity and logistical support theory (SILST)). I present these dimensionsâ indicators and demonstrate three-dimensional typology of Web innovation milestones anchored on the three dimensionsâa step forward in substantiating the frameworkâs applicability to media capacity characterization
CHORUS Deliverable 2.1: State of the Art on Multimedia Search Engines
Based on the information provided by European projects and national initiatives related to multimedia search as well as domains experts that participated in the CHORUS Think-thanks and workshops, this document reports on the state of the art related to multimedia content search from, a technical, and socio-economic perspective.
The technical perspective includes an up to date view on content based indexing and retrieval technologies, multimedia search in the context of mobile devices and peer-to-peer networks, and an overview of current evaluation and benchmark inititiatives to measure the performance of multimedia search engines.
From a socio-economic perspective we inventorize the impact and legal consequences of these technical advances and point out future directions of research
Prospects of Mobile Search
Search faces (at least) two major challenges. One is to improve efficiency of retrieving relevant content for all digital formats (images, audio, video, 3D shapes, etc). The second is making relevant information retrievable in a range of platforms, particularly in high diffusion ones as mobiles. The two challenges are interrelated but distinct. This report aims at assessing the potential of future Mobile Search. Two broad groups of search-based applications can be identified. The first one is the adaptation and emulation of web search processes and services to the mobile environment. The second one is services exploiting the unique features of the mobile devices and the mobile environments. Examples of these context-aware services include location-based services or interfacing to the internet of things (RFID networks).
The report starts by providing an introduction to mobile search. It highlights differences and commonalities with search technologies on other platforms (Chapter 1). Chapter 2 is devoted to the supply side of mobile search markets. It describes mobile markets, presents key figures and gives an outline of main business models and players. Chapter 3 is dedicated to the demand side of the market. It studies usersÂż acceptance and demand using the results on a case study in Sweden. Chapter 4 presents emerging trends in technology and markets that could shape mobile search. It is the author's view after discussing with many experts. One input to this discussion was the analysis of on forward-looking scenarios for mobile developed by the authors (Chapter 5). Experts were asked to evaluate these scenarios. Another input was a questionnaire to which 61 experts responded. Drivers, barriers and enablers for mobile search have been synthesised into SWOT analysis. The report concludes with some policy recommendations in view of the likely socio-economic implications of mobile search in Europe.JRC.DG.J.4-Information Societ
Collaboration in the Semantic Grid: a Basis for e-Learning
The CoAKTinG project aims to advance the state of the art in collaborative mediated spaces for the Semantic Grid. This paper presents an overview of the hypertext and knowledge based tools which have been deployed to augment existing collaborative environments, and the ontology which is used to exchange structure, promote enhanced process tracking, and aid navigation of resources before, after, and while a collaboration occurs. While the primary focus of the project has been supporting e-Science, this paper also explores the similarities and application of CoAKTinG technologies as part of a human-centred design approach to e-Learning
Auctioning Bulk Mobile Messages
The search for enablers of continued growth of SMS traffic, as well as
the take-off of the more diversified MMS message contents, open up for
enterprises the potential of bulk use of mobile messaging , instead of
essentially one-by-one use. In parallel, such enterprises or value
added services needing mobile messaging in bulk - for spot use or for
use over a prescribed period of time - want to minimize total
acquisition costs, from a set of technically approved providers of
messaging capacity.
This leads naturally to the evaluation of auctioning for bulk SMS or
MMS messaging capacity, with the intrinsic advantages therein such as
reduction in acquisition costs, allocation efficiency, and optimality.
The paper shows, with extensive results as evidence from simulations
carried out in the Rotterdam School of Management e-Auction room, how
multi-attribute reverse auctions perform for the enterprise-buyer, as
well as for the messaging capacity-sellers. We compare 1- and 5-round
auctions, to show the learning effect and the benefits thereof to the
various parties. The sensitivity will be reported to changes in the
enterprise's and the capacity providers utilities and priorities
between message attributes (such as price, size, security, and
delivery delay). At the organizational level, the paper also considers
alternate organizational deployment schemes and properties for an
off-line or spot bulk messaging capacity market, subject to technical
and regulatory constraints
Evaluation of M-Sites Using PDAs
As mobile sites (m-sites) are introduced a very relevant question to ask is âHow should these sites be different from the typical websites developed for desktop PCs?â This paper presents an initial, exploratory attempt to address some issues related to m-sites. This evaluation of sites was conducted using wireless PDAs in a WLAN environment. The results indicated that regular sites and m-sites differed significantly in perceived search engine functionality. The evaluated m-sites showed little differences across various industries. A discussion of these results as well as recommendations for managers and academic researchers are provided
