We study the dependence of citation counts of e-prints published on the arXiv:astro-ph server on their position in the daily astro-ph listing. Using the SPIRES literature database we reconstruct the astro-ph listings from July 2002 to December 2005 and determine citation counts for e-prints from their ADS entry. We use Zipf plots to analyze the citation distributions for each astro-ph position....

We present a compilation of predictions for the amplitudes of D 0 ?D 0 mixing. We are not aware of any exhaustive compilation of predictions for the amplitudes for D 0 !D 0. We have therefore found it helpful to compile, here, those predictions that we have found in a rudimentary search of the literature. We keep an annotated table of all of the references that we have found, hyperlinked where ...

Data description or metadata presents a significant database management challenge, particularly for scientific and statistical databases. Ideally, we would llke to access and manipulate data and metadata using the same DBMS tools, but there are few systems that even begin to provide such integrated capabilities. This paper outlines a framework for more integrated metadata management by synthesi...

INTRODUCTION We did formative evaluations of several variations to the computation of related articles for non-bibliographic resources in the medical domain. METHODS A binary model and several variations of the vector space model were used to measure similarity between documents. Two corpora were studied, using a human expert as the gold standard. RESULTS Variations in term weights and stop...

As more online databases are integrated into digital libraries, the issue of quality control of the data becomes increasingly important, especially as it relates to the eeective retrieval of information. The need to discover and reconcile variant forms of strings in bibliographic entries, i.e., authority work, will become more diicult. Spelling variants, misspellings, and transliteration diiere...

The principle of polyrepresentation and document clustering are two established methods for Interactive Information Retrieval, which have been used separately so far. In this paper we discuss a cluster based polyrepresentation approach for information need and document based representations. In our work we simulate and evaluate two possible cluster browsing strategies a user could apply to expl...

We have developed a computerized method for performing bibliographic searches directly from patient data involving five steps: 1) identifying specific patient data which raises a question in the mind of the user, 2) selection (from a list of generic questions) of a small number of questions which fit the selected patient data, 3) automated translation of the patient data into appropriate terms ...
