Abstract

The search for research seeds must be carried out using broad terms, because the query is not always initially clear; a hopeful research seed is hidden among various sets of information that has been searched for. We propose a method of investigation using exploratory filtering. First, we search for Chemical Abstracts using the name of a disease. Consequently, a great deal of obtained document sets is filtered using a dictionary of known information. After filtering, the remaining information is arranged in a list of research seeds pertaining to pharmaceuticals. We searched for literature using the search tag “breast cancer”, and filtered out the normal targets for the specific search. Subsequently, we obtained a list of novel action mechanisms. The exploratory filtering proposed in this paper is useful for finding research seeds from within hundreds of documents. We believe an investigation of research seeds has been improved using the proposed methodology.
