A Concept for Using Combined Multimodal Queries in Digital Music Libraries

Περιέχει το πλήρες κείμενοIn this paper, we propose a concept for using combined multimodal queries in the context of digital music libraries. Whereas usual mechanisms for content-based music retrieval only consider a single query mode, such as query-by-humming, full-text lyrics-search or query-by-example using short audio snippets, our proposed concept allows to combine those different modalities into one integrated query. Our particular contributions consist of concepts for query formulation, combined content-based retrieval and presentation of a suitably ranked result list. The proposed concepts have been realized within the context of the PROBADO Music Repository and allow for music retrieval based on combining full-text lyrics search and score-based query-by-example search

What We Expect from Digital Libraries

Digital Libraries have been the subject of more than a decade of attention by researchers and developers, and yet in all this time the implementations have not matched the promises. By far the majority of systems have concentrated on content and provided limited or basic functions for users. In this article we offer a new look at what can be expected from a digital library system based on contemporary developments in Information and Communications Systems and Technology. First, we sketch out the basic functions which are provided to support finding and accessing material by a reader. Next we explain some extended functions which support the use and re-use of documents - links and annotations and the need to support learners in addition to readers and writers. Finally, we present our visions for a modern digital library and e-Learning portal system which includes for example intelligent and conceptual search support including results visualization, white lists, and adaptive user interfaces

Important aspects of modern digital libraries

Digital Libraries have been the subject of more than a decade of attention by researchers and developers, and yet in all this time implementations have not matched the promises. Even today, when there is new wave of enthusiasm for digital libraries based on a number of open access initiatives, the majority of systems is concentrating on content and provides limited or just basic functions for users. In this paper we first discuss some aspects from a digital library initiatives. We then present what we believe can be expected from a digital library system based on current developments in information technology. We explain the basic functions, which are required to support finding and accessing material by a reader. Next we explain some extended functions, which support the use and re-use of documents-links and annotations-and the need to support learners in addition to readers and writers. Finally, we present our vision for and our concerns about large digital libraries and e-learning portal systems. Our vision include for example intelligent and conceptual search including results visualization, white lists and adaptive user interfaces. Our concerns are based on a dramatic increase in plagiarism due to the massive amounts of information that is ready for everyone to copy and paste, a fact that may impact on how we conduct and deal with publications in the future
