Searching the Físchlár-NEWS archive on a mobile device

The Físchlár-NEWS system provides web-based access to an archive of digitally recorded TV News broadcasts over several months, and has been operational for over a year. Users can browse keyframes, search teletext and have streamed video playback of segments of news broadcasts to their desktops. This paper reports on the development of mFíschlár-NEWS, a version of Físchlár-NEWS which operates on a mobile PDA over a wireless LAN connection. In the design and development of mFíschlár-NEWS we have realised that mobile access to a digital library of video materials is more than just the desktop system on a smaller screen, and the functionality and role that information retrieval techniques play in the mFíschlár-NEWS system are very different to what is present in the desktop system. The paper describes the design, interface, functionality and operational status of this mobile access to a video library

Dublin City University video track experiments for TREC 2001

Dublin City University participated in the interactive search task and Shot Boundary Detection task* of the TREC Video Track. In the interactive search task experiment thirty people used three different digital video browsers to find video segments matching the given topics. Each user was under a time constraint of six minutes for each topic assigned to them. The purpose of this experiment was to compare video browsers and so a method was developed for combining independent users’ results for a topic into one set of results. Collated results based on thirty users are available herein though individual users’ and browsers’ results are currently unavailable for comparison. Our purpose in participating in this TREC track was to create the ground truth within the TREC framework, which will allow us to do direct browser performance comparisons

A news video retrieval framework for the study of implicit relevance feedback.

In this paper, we propose a framework for recording, analysing, indexing and retrieving news videos such as the BBC one o'clock news. We believe that such a framework will be useful to identify implicit indicators of relevance, a nearly untouched area in adaptive multimedia retrieval. Due to its advantages as a Web application and its up-to-date content, it can be a promising approach to motivate a broad quantity of users to interact with the system

MEPs online: Understanding communication strategies for remote representatives

This article explores the use of the Internet by Members of the European Parliament (MEPs), assessing the adoption of online communication as well as its strategic uses. In particular we analysed the websites, weblogs and social networking site profiles of all MEPs who linked to an online presence from the European parliament homepage, a total of 440 MEPs representing all 27 member nations. Through a thorough analysis of the content using a scheme designed to record the presence and functionality of 103 specific features and tools and recency of updates, we assess how MEPs use the Internet to connect with a range of audiences; from journalists to loyal supporters. We find MEPs embracing a range of features which would be appealing to a wide range of different visitors. There is a minor generational divide among MEPs based both on their age and the length of time their country has been a member of the European Union. However overall we suggest there is an ebb and flow of innovation within the online political communication of these parliamentarians

Broadcasting to the masses or building communities: Polish political parties online communication during the 2011 election

The professionalisation of political communication is an evolutionary process (Lilleker & Negrine, 2002), a process that adapts to trends in communication in order to better engage and persuade the public. One of the most dramatic developments in communication has been the move towards social communication via the Internet. It is argued to affect every area of public communication, from commercial advertising and public relations to education (Macnamara, 2010). It is no longer sufficient to have an online presence; we are now in an age of i-branding; with the ‘i’ standing for interactive. Yet, trends in online political electoral campaigning over recent years indicate a shallow adoption of Web 2.0 tools, features and platforms; limited interactivity; and managed co-production. The Internet is now embedded as a campaigning tool however, largely, the technologies are adapted to the norms of political communication rather than technologies impacting upon internal organizational structures, party relationships to members and supporters, or the content and style of their communication. We examine these themes, and develop them through a focus on the targeting and networking strategies of political parties, in more detail in the context of the Polish parliamentary election of 2011. Through a sophisticated content analysis and coding scheme our paper examines the extent to which parties use features that are designed to inform, engage, mobilise or allow interaction, which audiences they seek to communicate with and how these fit communication strategies. Comparing these findings with maps built from webcrawler analysis we build a picture of the strategies of the parties and the extent to which this links to short and long term political goals. This paper firstly develops our rationale for studying party and candidate use of the Internet during elections within the Polish context. Secondly we develop a conceptual framework which contrasts the politics as usual thesis (Margolis & Resnick, 2000) with arguments surrounding the social shaping of technologies (Lievrouw, 2006) and the impact on organisational adoption of communication technologies and post-Obama trends in Internet usage (Lilleker & Jackson, 2011) and posit that, despite the threats from an interactive strategy (Stromer-Galley, 2000) one would be expected within the context of a networked society (Van Dyjk, 2006). Following an overview of our methodology and innovative analysis strategy, we present our data which focuses on three key elements. Firstly we focus on the extent to which party and candidate websites inform, engage, mobilise or permit interaction (Lilleker et al, 2011). Secondly we assess the extent to which websites attract different visitor groups (Lilleker & Jackson, 2011) and build communities (Lilleker & Koc-Michalska, 2012). Thirdly we assess the reach strategies of the websites using Webcrawler technology which analyses the use of hyperlinks and whether parties lock themselves within cyberghettoes (Sunstein, 2007) or attempt to harness the power of the network (Benkler, 2006)
