Different professions adopt their own language such that the semantics involves elements very specific to their domain. System developers approaching users in a new domain often experience initial difficulties when trying to understand what takes place at work. Since most software developers also lack knowledge of human-computer interaction (HCI), we have been investigating means of transferrin...

We explore the availability and persistence of URLs cited in articles published in D-Lib Magazine. We extracted 4387 unique URLs referenced in 453 articles published from July 1995 to August 2004. The availability was checked three times a week for 25 weeks from September 2004 to February 2005. We found that approximately 28% of those URLs failed to resolve initially, and 30% failed to resolve ...

MOTIVATION In a previous paper, we presented a polynomial time dynamic programming algorithm for predicting optimal RNA secondary structure including pseudoknots. However, a formal grammatical representation for RNA secondary structure with pseudoknots was still lacking. RESULTS Here we show a one-to-one correspondence between that algorithm and a formal transformational grammar. This grammar...
