Text and spatial data mining

Parcellation of the human brain Parcellation of the human brain by combining text mining and spatial data mining within a neuroinformatics database. Text mining: Analysis of scientific abstracts. Spatial data mining: Modeling of the distribution of Talairach coordinates. Seek communality between the the text representation and spatial representation by multivariate analysis

Databasing Molecular Neuroimaging

Molecular neuroimaging Most molecular imaging studies relies on analysis of values from brain regions and report descriptive statistics for these values. There are two significant difficulties when comparing molecular neuroimaging studies: 1. Regions differ between studies: E.g., some include values for “temporal cortex ” others do not. 2. Measured and reported values differ between studies and they are not comparable: Tracers and receptors; transport rates (e.g., K1), distribution volume, binding potentials; different methods to compute the values

Scientific citations in Wikipedia

The Internet-based encyclopaedia Wikipedia has grown to become one of the most visited Web sites on the Internet, but critics have questioned the quality of entries. An empirical study of Wikipedia found errors in a 2005 sample of science entries. Biased coverage and lack of sources are among the "Wikipedia risks." This paper describes a simple assessment of these aspects by examining the outbound links from Wikipedia articles to articles in scientific journals with a comparison against journal statistics from Journal Citation Reports such as impact factors. The results show an increasing use of structured citation markup and good agreement with citation patterns seen in the scientific literature though with a slight tendency to cite articles in high-impact journals such as Nature and Science. These results increase confidence in Wikipedia as a reliable information resource for science in general
