Many segments of modern society desire the ability to find relationships, thus meaning, in public discourse. Notable segments include marketing, politics, government, activism and public safety. The increasing use of the Internet for public dialog has made Internet communication a potentially rich source of information in this regard. This study explores the use of an Interactive Activation with Competition (IAC) artificial neural network to aid in processing text to find relationships. A fully recurrent IAC network was modified to process text in a continuous fashion, adding nodes as new terms were encountered. Forty-nine email messages from two threads in the Open Library/Information Science Education Forum were processed using two variations in the self-organizing phase of network formation. The messages were processed with and without a linear decay function applied to the external activation of nodes between sentences. With the function self-organization includes reduced external activation levels of terms in sentences that have already been processed in the current message. Without it self-organization externally activates only terms in the sentence currently being processed. This could be considered a type of context control. The use of the linear decay function produced three effects. When the function was used, roughly half the number of noise strings were highly associated with key terms; the entire network was more differentiated from key terms and; the key terms were more highly associated with each other. These effects could reduce or eliminate the need for stop word filtering as well as improve system performance. Future research should explore refinements in this concept, as well as its ability to disambiguate terms. Combining this approach with models of discourse structure is another area for research.
