Abstract

This paper includes some of the results of a study that looks at three types of text for automatically deriving shot-level indexing to moving images. Audio description is a voice added to the sound track of moving pictures to provide information for the visually impaired. We analyse two one-hour parts of a television production broadcast as a mini-series in 1997. We compare our results with those of a previous study, which identifies some of the characteristics of audio description and the associated moving image. We found close correspondence among some aspects studied and for other aspects muck less correspondence, but for reasons we are able to explain. In addition, in the process of conducting the current study we further developed our methodology and now feel that it is a mature method for analysing audio description text as a source for generating indexing to the associated moving image.

Content

Merely translating web sites is not sufficient for serving international clienteles. Web sites need to be "localised". This involves adapting various informational aspects to address the local population in such a way that users understand the content and its use in the context of their own culture. A cultural marker denotes a convention used on a web site to address a particular population. Research in the area of localisation has concentrated on commercial web sites and software. We found that localisation of cultural web sites increases the complexity of the information management issues. As a project of the Section on Audiovisual and Multimedia of IFLA, a kind for localising the The Moving Image Collections (MIC) site was developed, then tested by using it to localise a selection of pages from the web site in French, Spanish, and Arabic. The kit, in the form of a .pdf file, can be used to produce a version of the MIC site localised for any other language or ethnic community.

Abstract

The University of Toronto hopes to encourage development of a campus-wide information system consisting of many walk-up-and-use components. The first component to be developed was an instructional program for users of the library's online catalog. The interface had to be attractive, usable by novices, and flexible enough to carry the content. Much effort was expended in ensuring that it met these criteria. User testing played an important role in the design of the interface. The design and testing of the system's entry point, navigation aids, and templates for spatial arrangements of information on the screen are discussed

Abstract

Indexing methods for audiovisual materials had not yet settled when the arrival of the World Wide Web upset any stability that existed in this area. New possibilities have now opened up for indexing digital audiovisual materials in a networked environment. This article, traces some of the methods used for organizing collections of audiovisual materials, give a general portrait of how various types of them are organized today, and using indicators that have become manifest, speculate on some future developments in this area.

Abstract

In previous research, participants who screen a videotape of stock footage from the National Film Board of Canada's stockshot collection were asked to assign terms in English that could be used for retrieval of each shot. The most popular terms were analyzed as potential indexing terms. In the current research a French language version of the research tapes was prepared, using the same images, and the data collected were in French. Compares the most popular terms identified in each of the 2 studies for each of the shots in order to determine the rate of correspondence between potential indexing terms in each language

Abstract

Several types of moving images are available now, and each has its own indexing needs. In addition, a number of levels of indexing are necessary, depending on the type of image, the type of collection, and the needs of users. In information science, work on providing indexing to the various levels has largely to do with finding ways to recycle text created for other purposes in the processes of production, in order to point to individual shots, sequences, scenes, or chapters. Such text recycling needs to happen automatically, through the application of algorithms developed for this purpose, since indexing at the various levels by humans is prohibitively expensive in most circumstances. Multilingual indexing is an issue in the context of retrieving images in a networked environment. Another issue is access to moving images using indexing approaches other than subject indexing. Tagging of images by users is prevalent in the networked environment, and a discussion of its usefulness is included. Finally, there is some speculation on what the future of moving image indexing might bring.

Abstract

Most moving image collections have existed for less than a century, and as we enter the new millennium we observe that the organisation of these collections is still characterized by ad hoc practices. An important stream of research in this area focuses on high-level access to images using methods from library and information science, and using text to create information useful for retrieval. It has been established that common names for objects seen in the image are the key to retrieval in such collections. On a day-to-day basis, those responsible for collection management build indexing vocabularies, creating terms as necessary, and often structuring them loosely into a thesaurus. Discussions with moving image collection librarians have led us to believe that there may be an optimal number of common names a thesaurus for managing general collections of moving images should contain, and that the terms may even be the same from one thesaurus to the next. In this paper, we describe the methodology adopted for studying this question, and report preliminary results

Abstract

Mental models are employed in building and using computer systems. It is not easy for authors to agree on suitable terminology for referring to the concepts arising from the need to discuss models and modelling activity resulting in confusion. Discusses this confusion, and attempt to sort out the various meanings found in the literature. Offers definitions that could help in developing a more standardized terminology for discussing issues of concern to researchers in human-computer interaction. Discusses the role mental models play in learning and using information retrieval systems

Abstract

Previous research on shot level indexing of moving image documents identified the terms supplied most often by participants to describe a selection of shots from the National Film Borard of Canada's stockshot collection. The most popular terms supplied by participants in the study were compared with the terms assigned by professional indexers for these shots in the source files. Records for some of the shots used in the original study came from the stockshot library's computer database, and the remaining records came from its older card file. Findings indicate agreement between the terms users think of when searching film and video shots and those indexers assign to them

Abstract

Access to audiovisual materials should be as open and free as access to print-based materials. However, we have not yet achieved such a reality. Methods useful for organising print-based materials do not necessarily work well when applied to audiovisual and multimedia materials. In this project, we studied using audio description text and written descriptions to generate keywords for indexing moving images. We found that such sources are fruitful and helpful. In the second part of the study, we looked at the possibility of automatically translating keywords from audio description text into other languages to use them as indexing. Here again, the results are encouraging.
