Indexing is the core component of most information retrieval systems, because it allows for a compact representation of the content of a collection of documents, aimed at efficient and scalable access and retrieval. Indexing techniques can be extended also to music, providing that significant descriptors are computed from music documents. These descriptors can be defined as the “lexical units” ...

The technical structure of the Mexican science and technology literature was determined. A representative database of technical articles was extracted from the Science Citation Index for the year 2002, with each article Correspondence to: Ronald N. Kostoff, Office of Naval Research, 875 N. Randolph St, Arlington, VA 22217, USA. E-mail: [email protected] © 2007 Chartered Institute of Library ...

Information retrieval over clustered document collections has two successive stages: first identifying the best-clusters and then the best-documents in these clusters that are most similar to the user query. In this paper, we assume that an inverted file over the entire document collection is used for the latter stage. We propose and evaluate algorithms for within-cluster searches, i.e., to int...

The paper introduces simple bibliometric-enhanced search facilities which are derived from the famous stratagems by Bates. Moves, tactics and stratagems are revisited from a Digital Library perspective. The potential of extended versions of ”journal run” or ”citation search” for interactive information retrieval is outlined. The authors elaborate on the future implementation and evaluation of n...

Network pruning can effectively reduce a model's capacity and computational load, thereby making model deployment in mobile devices less difficult than that without pruning. To improve the rate of while maintaining kernel's feature extraction ability, this paper designs progressive kernel method for CNN compression based on proposed information mapping sparsity index. This first prunes kernels ...
