We present a methodology for automatically constructing structural hyperlinks for navigation and retrieval in large corpora. A structural hyperlink connects components of a document that have specified structural properties with word-based content similarity. Our approach enables queries that may be posed in terms of keywords, as well as structural segments such as definitions, figures, etc.

Visualization with a hierarchy of mathematical knowledge structure, assist learners in understanding mathematics. We are developing a method which constructs a hierarchy of mathematical knowledge by using hyperlink analysis in our mathematics e-learning site. Hierarchy is calculated by an adjacency matrix. 

The case of Eldred v. Ashcroft focused the public’s attention on the question of the duration of a copyright owner’s right. An even more compelling problem is raised by the scope of the property right associated with copyright. Statutorily, the copyright owner is granted the exclusive rights of reproduction, distribution, adaptation, public performance, and public display subject to the doctrin...

BACKGROUND Highlighted text in the Internet (i.e., hypertext) is predominantly blue and underlined. The perceptibility of these hypertext characteristics was heavily questioned by applied research and empirical tests resulted in inconclusive results. The ability to recognize blue text in foveal and parafoveal vision was identified as potentially constrained by the low number of foveally centere...

The ammonia monooxygenase (AMO) of Nitrosomonas europaea is a metalloenzyme that catalyses the oxidation of ammonia to hydroxylamine. We have identified histidine 191 of AmoA as the binding site for the oxidized mechanism-based inactivator acetylene. Binding of acetylene changed the molecular mass of His-191 from 155.15 to 197.2 Da (+42.05), providing evidence that acetylene was oxidized to ket...
