2021 arXiv   pre-print
Explainable AI (XAI) has been investigated for decades and, together with AI itself, has witnessed unprecedented growth in recent years.  ...  We overview the literature focusing on different types of explanation (intrinsic and post-hoc), different models with which argumentation-based explanations are deployed, different forms of delivery, and  ...  Acknowledgements This research was funded in part by the Royal Academy of Engineering, UK, and by J.P.

Mieczysław A.Kłopotek, Sławomir T.Wierzchoḿ, Robert A. Kłopotek, Elżbieta A. Kłopotek
2017 arXiv   pre-print
In a former paper we simplified the proof of a theorem on personalized random walk that is fundamental to graph nodes clustering and generalized it to bipartite graphs for a specific case where the proobability  ...  So let us briefly explain the notion of semantic search engine and its impact on ranking method requirements. Semantics of information 10 expresses the meaning of this information.  ...  Traditional PageRank One of the many interpretations of PageRank views it as the probability that a knowledgeable (knowing addresses of all the web pages) but mindless (choosing next page to visit without  ...

Google and the Mind

Thomas L. Griffiths, Mark Steyvers, Alana Firl
2007 Psychological Science  
We show that PageRank, computed on a semantic network constructed from wordassociation data, outperformed word frequency and the number of words for which a word is named as an associate as a predictor  ...  We explored whether they employ similar solutions, testing whether we could predict human performance on a fluency task using PageRank, a component of the Google search engine.  ...  RESULTS PageRank and associate frequency were calculated using a semantic network constructed from the word-association norms of Nelson, McEvoy, and Schreiber (1998) .  ...

Visualizing large knowledge graphs: A performance analysis

Juan Gómez-Romero, Miguel Molina-Solana, Axel Oehmichen, Yike Guo
2018 Future generations computer systems  
Currently, Semantic Web technologies are prevalent for modelling and querying knowledge graphs; however, most visualization approaches in this area tend to be overly simplified and targeted to small-sized  ...  To do so, we have implemented a graph processing pipeline in the Apache Spark framework and carried out several experiments with real-world and synthetic graphs.  ...  In this regard, Sowa's conceptual graphs bring together the interpretability of visual semantic networks and the formal underpinnings of first-order logic [26] .  ...
