The paper proposes a text-mining based analytical framework aiming at the cognitive organization of complex scientific discourses. The approach is based on models recently developed in science mapping, being a generalization of the so-called Science Overlay Mapping methodology, referred to as Topic Overlay Mapping (TOM). It is shown that via applications of TOM in visualization, document cluste...

DOWNIE, S. R., and K. E. DENFORD. 1987. The biosystematics of Amicafilgens and A. sororia (Asteraceae). Can. J . Bot. 65: 559 -570. Amicafilgens Pursh and A. sororia Greene are sympatric throughout most of their ranges in northwestern United States and adjacent southwestern Canada. These taxa were previously recognized as two morphologically overlapping varieties or not very well separated spec...

This article presents an unsupervised algorithm for semantic annotation of morphological descriptions of whole organisms. The algorithm is able to annotate plain text descriptions with high accuracy at the clause level by exploiting the corpus itself. In other words, the algorithm does not need lexicons, syntactic parsers, training examples, or annotation templates.The evaluation on two real-li...
