The “Físchlár ” systems are a family of tools for capturing, analysis, indexing, browsing, searching and summarisation of digital video information. Físchlár-News-Stories, described in this paper, is one of those systems, and provides access to a growing archive of broadcast TV news. Físchlár-News-Stories has several notable features including the fact that it automatically records TV news and segments a broadcast news program into stories, eliminating advertisements and credits at the start/end of the broadcast. Físchlár-News-Stories supports access to individual stories via calendar lookup, text search through closed captions, automatically-generated links between related stories, and personalised access using a personalisation and recommender system based on collaborative filtering. Access to individual news stories is supported either by browsing keyframes with synchronised closed captions, or by playback of the recorded video. One strength of the Físchlár-News-Stories system is that it is actually used, in practice, daily, to access news. Several aspects of the Físchlár systems have been published before, bit in this paper we give a summary of the Físchlár-News-Stories system in operation by following a scenario in which it is used and also outlining how the underlying system realises the functions it offers.

In this paper we describe a project that explores how advances in information technology could be used to make film and television media more accessible to both scholarly and non-scholarly audiences. By indexing, at a detailed level, a range of time-synchronized and non-time-synchronized elements in a test collection of 12 films and 8 television programs, we demonstrate how structured data representing many aspects of media content can be produced in a streamlined manner, and discuss how this work could potentially be augmented with automated indexing to be more efficient. We present examples of how this data can be utilized to produce a variety of tools and artifacts that make film and television media more accessible, and suggest that crowdsourcing could be an effective strategy for accomplishing this work on a larger scale. This research contributes to the growing body of literature exploring how multimedia collections can be made more accessible and useful for a variety of purposes.

This paper presents a methodical approach for generating deep knowledge about users, as a prerequisite for design and construction of digital information access to cultural heritage information objects. We exemplify this methodical approach by reporting on an explorative study of information need characteristics in a television broadcast context. The methodical approach is inspired by naturalistic research, and our main data is nine in-depth interviews conducted with scholars and students within the academic field of Media Studies. The analysis identifies four characteristics. Firstly, broadcasts are needed as objects of analysis in empirical research. Secondly, the needs are related to three broadcast dimensions: 1) Transmission; 2) Archive; and 3) Reception. Thirdly, four fundamental types of information needs are verified in a television broadcast context: 1) Known item; 2) Factual data; 3) Known topic or content; and 4) Muddled topic or content. Fourthly, the interviewees ’ needs consist of four phases: 1) Getting an overview of transmitted broadcasts; 2) Identification of borderline exemplars; 3) Selection of specific programmes; and 4) Verification of facts. The present paper presents novel research on characteristics of information needs in a television broadcast context. We demonstrate how one may go about generating knowledge which is imperative for the design and construction of future broadcast retrieval systems. 1.

Approaches tested: The goal of this study was to investigate the effects of providing context and interactivity in a retrieval system, supporting the browsing of search result sets. Thus, three systems were developed: (1) a basic system, modeled on the current results list provided by google video searching (runs UNC-BAS-1 and UNC-BAS-2); (2) a similar system, with the context of each shot provided by showing keyframes from the shots appearing just before and after the retrieved shot (runs UNC-CON-1 and UNC-CON-2); and (3) a system that builds on the previous system by offering several mechanisms of interactivity (runs UNC-INT-1 and UNC-INT-2). Comparative findings: In terms of both performance and user perceptions, the Context+Interactive system was superior. While there were no differences in precision, recall was improved with this system, and users preferred it (based on several measures of user perceptions). Conclusions: The effects of context on browsing search results were negligible, but should be explored further through re-examination of the definition and operationalization of the concept of context. Interactivity, in combination with context, had positive effects on browsing effectiveness; it was considered easy to use, even though it introduced more complexity into the interface. 1

Abstract. This paper describes our work in developing a movie browser application for students of Film Studies at our University. The aim of our work is to address the issues that arise when applying conventional user-centered design techniques from the usability engineering field to build a usable application when the system incorporates novel multimedia tools that could be potentially useful to the end-users but have not yet been practiced or deployed. We developed a webbased system that incorporates features as identified from the students and those features from our novel video analysis tools, including scene detection and classification. We deployed the system, monitored usage and gathered quantitative and qualitative data. Our findings show those expected patterns and highlighted issues that need to be further investigated in a novel application development. A mismatch between the users ’ wishes at the interviews and their actual usage was noted. In general, students found most of the provided features were beneficial for their studies.

Abstract: Technological developments in content-based analysis of digital video information are seeing much progress, with ideas for fully-automatic systems being proposed and now demonstrated. Yet because we do not yet have robust, operational video retrieval systems that could be deployed and used by people the usual HCI practise of conducting a usage study and an informed iterative system design is thus not possible. Físchlár-News is one of the first line of automatic, content-based broadcast news analysis and archival systems that process broadcast news video to allow users to search, browse and play it in an easy to use manner using a conventional web browser. The system incorporates a number of state-of-the-art research components, some of which are not yet considered as mature technology, yet it has been built to be robust enough to be deployed to users who are interested in access to daily news, throughout a university campus. In this paper we report and discuss a user evaluation study conducted with 16 users, each of whom used the system freely for a 1 month period. Results from a detailed qualitative analysis are presented, looking at collected questionnaires, incident diaries and interaction log data. The findings suggest our users used the system in conjunction with their other news update methods such as watching TV news at home and browsing online news websites at their workplace, the major concerns being up-to-datedness and coverage of the news content. They tried to accommodate the system to fit their established web browsing habits, and they found local news contents and being able to play self-contained news stories on their desktop as a major value of the system. Our study also resulted in a detailed wishlist of new features which will help
