Audiovisual collections – turning sound and vision into data

2nd of February, 9am–4.30pm at the National Library of Sweden: The potential indicated in the expression “a picture says more than thousand words” is today gradually being fulfilled in its literal sense.

The development of digital applications for information processing means that this saying now comprises not only still-images (as in Optical Character Recognition) but also extends to information extraction in relation to moving images and sound (i.e. speech to text, object and feature detection). How can this technology be used to enhance the management of audio-visual collections within the heritage sector?

Heritage institutions have traditionally relied on manual methods for classification and indexing of the holdings. Audio-visual material has always presented challenges in this respect due to the dependency on technical equipment for access. This aspect makes the description of audio-visual content a resource intensive and time-consuming task, and potentially an insurmountable obstacle in relation to large collections.

The possibility of information extraction offered by the digital format is increasingly utilised in the management of text-based documents. The transfer to machine readable text enables automated methods of indexing and genre identification as well as research approaches, based on data driven analysis, commonly referred to as Text and Data Mining. Similar applications are found in relation to audio-visual information carriers although here the development tends to be driven by commercial interests rather than the need among heritage institutions to improve the management of their collections. The digital format consequently offers a great, and in many respects unexploited, potential for the dissemination of audio-visual content across the boundaries posed by the traditional institutional types within the heritage sector.

This conference is intended to present research projects and running operations where digital methods are used in order to extract text and metadata from audio-visual collections. We will examine some challenges and potential promises in this area and at the same time hopefully inspire to further development and applications among the institutions and organisations that manage audio-visual collections.
