A Cognitive Mind-Map Framework to Foster Trust

Abstract

The explorative mind-map is a dynamic framework, that emerges automatically from the input, it gets. It is unlike a verificative modeling system where existing (human) thoughts are placed and connected together. In this regard, explorative mind-maps change their size continuously, being adaptive with connectionist cells inside; mind-maps process data input incrementally and offer lots of possibilities to interact with the user through an appropriate communication interface. With respect to a cognitive-motivated situation like a conversation between partners, mind-maps become interesting as they are able to process stimulating signals whenever they occur. If these signals are close to an own understanding of the world, then the conversational partner becomes automatically more trustful than if the signals do not or less match the own knowledge scheme. In this (position) paper, we therefore motivate explorative mindmaps as a cognitive engine and propose these as a decision support engine to foster trust. Explorative Mind-mapsThe principles of explorative mind-maps M i have already been described in [11], where we accent that mind-maps rely on the natural principle on sensations and the corresponding propagation of stimuli to a final destination. Indeed, explorative mind-maps share this principle through an associative architecture that incrementally processes accepted stimuli to a consistent informational structure. This is similar to the natural paradigm, but on contrast to a verificative processing of a user's thoughts, the explorative mind-maps are built from the bottom up, meaning that their existence exclusively interdepend on incoming signals.Explorative mind-maps share a sub-symbolic architecture that is composed of interacting entity cells e i . As mentioned above for the natural principle, these cells foster on a processing of data streams and a stimulation/inhibitionprinciple of adjacent connections. The activation of such a connectionist architecture bases on a dynamic construction of cell structures during the processing of the input stream.In the stimulation phase, a stream data is stimulated and absorbed by receptor (input) cells r i , which decompose the Figure 1: Merge between the existing mind-map a) and a (newly) mini-network b) to an updated mind-map c).

For example, the text streams are decomposed into the word entities, transactional streams to item entities, and so on. Using filter cells f i , those receptor cells r i are inhibited that do not address a semantic interest. In the Mini-Network phase, the collection of entities, which occur at such a specific time-point, form a mini-network [6] with fully connected mini-network cells m i . The Mindmap Merger starts once the mini-network is established: in this phase, the mini-network is sent to the mind-map and is merged with the existing entity cells in the mindmap (initially, the mind-map is empty...

Operations on Conversational Mind-Graphs

“…As stated, the merge function µ is a real valued function, which represents the similarity between vertices (cells) and the associated connections of the mind-graphs [Poray and Schommer, 2009]. Actually, the degree of similarity corresponds to the common information inside these mind-graphs.…”

“…As described in [Poray and Schommer, 2009], a skeleton is a mind-graph with strong connections (threshold) between its vertices. The extraction procedure follows an algorithm, which is described in the following.…”

“…For example, a text summarisation method LexRank has been suggested by [Radev, 2004], where each vertex corresponds to the extracted topic from the input text and connection to the relation between several topics. In [Poray and Schommer, 2009] it has been shown that each conversing person can receive an understanding of its partner, if all incoming textual stimuli are linguistically processed and then put to a associative framework (mind-graph): the idea is that strong and weak connections -which emerge depending on the intensity and frequency of the signals -then finally lead to even such associative mindgraphs, which do not only reflect a textual conversation but moreover support a mental representation of the "other". And of course, a mental representation inside an associative framework can also be performed to the self of a person: a similarity (and dissimilarity) of these mind-graphs (the other's and the self) can become highly interesting regarding a mutual estimation (confidence, trust, et cetera).…”
