  • A Physical Metaphor to Study Semantic Drift
  • 2016
  • Ingår i: Proceedings of SuCCESS-16, 1st International Workshop on Semantic Change & Evolving Semantics. - 9781450321389
  • Konferensbidrag (refereegranskat)abstract
    • In accessibility tests for digital preservation, over time we experience drifts of localized and labelled content in statistical models of evolving semantics represented as a vector field. This articulates the need to detect, measure, interpret and model outcomes of knowledge dynamics. To this end we employ a high-performance machine learning algorithm for the training of extremely large emergent self-organizing maps for exploratory data analysis. The working hypothesis we present here is that the dynamics of semantic drifts can be modeled on a relaxed version of Newtonian mechanics called social mechanics. By using term distances as a measure of semantic relatedness vs. their PageRank values indicating social importance and applied as variable ‘term mass’, gravitation as a metaphor to express changes in the semantic content of a vector field lends a new perspective for experimentation. From ‘term gravitation’ over time, one can compute its generating potential whose fluctuations manifest modifications in pairwise term similarity vs. social importance, thereby updating Osgood’s semantic differential. The dataset examined is the public catalog metadata of Tate Galleries, London.

  • A Potential Surface Underlying Meaning?
  • 2015
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • Machine learning algorithms utilizing gradient descent to identify concepts or more general learnables hint at a so-far ignored possibility, namely that local and global minima represent any vocabulary as a landscape against which evaluation of the results can take place. A simple example to illustrate this idea would be a potential surface underlying gravitation. However, to construct a gravitation-based representation of, e.g., word meaning, only the distance between localized items is a given in the vector space, whereas the equivalents of mass or charge are unknown in semantics. Clearly, the working hypothesis that physical fields could be a useful metaphor to study word and sentence meaning is an option but our current representations are incomplete in this respect.For a starter, consider that an RBF kernel has the capacity to generate a potential surface and hence create the impression of gravity, providing one with distance-based decay of interaction strength, plus a scalar scaling factor for the interaction, but of course no term masses. We are working on an experiment design to change that. Therefore, with certain mechanisms in neural networks that could host such quasi-physical fields, a novel approach to the modeling of mind content seems plausible, subject to scrutiny.Work in progress in another direction of the same idea indicates that by using certain algorithms, already emerged vs. still emerging content is clearly distinguishable, in line with Aristotle’s Metaphysics. The implications are that a model completed by “term mass” or “term charge” would enable the computation of the specific work equivalent of sentences or documents, and that via replacing semantics by other modalities, vector fields of more general symbolic content could exist as well. Also, the perceived hypersurface generated by the dynamics of language use may be a step toward more advanced models, for example addressing the Hamiltonian of expanding semantic systems, or the relationship between reaction paths in quantum chemistry vs. sentence construction by gradient descent.

  • Conceptual machinery of the mythopoetic mind : Attis, a case study
  • 2015
  • Ingår i: Proceedings of QI-15, 9th International Quantum Interaction Symposium.
  • Konferensbidrag (refereegranskat)abstract
    • In search for the right interpretation regarding a body of related content, we screened a small corpus of myths about Attis, a minor deity from the Hellenistic period in Asia Minor to identify the noncommutativity of key concepts used in storytelling. Looking at the protagonist's typical features, our experiment showed incompatibility with regard to his gender and downfall. A crosscheck for entanglement found no violation of a Bell inequality, its best approximation being on the border of the local polytope.

  • Connecting the Dots : Mass, Energy, Word Meaning, and Particle-Wave Duality
  • 2012
  • Konferensbidrag (refereegranskat)abstract
    • With insight from linguistics that degrees of text cohesion are similar to forces in physics, and the frequent use of the energy concept in text categorization by machine learning, we consider the applicability of particle-wave duality to semantic content inherent in index terms. Wave-like interpretations go back to the regional nature of such content, utilizing functions for its representation, whereas content as a particle can be conveniently modelled by position vectors. Interestingly, wave packets behave like particles, lending credibility to the duality hypothesis. We show in a classical mechanics framework how metaphorical term mass can be computed.

  • Examples of Formulaity in Narratives and Scientific Communication
  • 2010
  • Ingår i: Proceedings of the 1st International AMICUS Workshop, October 21, 2010, Vienna, Austria. - : University of Szeged, Hungary. - 9789633060698 ; , s. 29-35
  • Konferensbidrag (refereegranskat)abstract
    • The AMICUS project was designed to promote scholarly networking in a topical area, motif recognition in texts, including its automation. Prior to doing so however it is necessary to show the theoretical underpinnings of the research idea. My argument is that evidence from different disciplines amounts to fragmented pieces of a bigger picture. By compiling them like pieces of a puzzle, one can see how the concept of formulaity applies to folklore texts and scholarly communication alike. Regardless of the actual name of the concept (e.g. motif, function, canonical form), what matters is that document parts and whole documents can be characterized by standard sequences of content elements, such formulaic expressions enabling higher-level document indexing and classification by machine learning, plus document retrieval. Information filtering plays a key role in the proposed technology.

  • First- and second-order change as symmetry and symmetry breaking in folklore text content evolution : From Heraclitus to Lévi-Strauss
  • 2007
  • Konferensbidrag (refereegranskat)abstract
    • We distinguish between first- and second order change and identify the former with perpetual alternation on an existential plane, the second with moving out into existential space. The first type can be demonstrated by two antagonistic processes inherent in a Markov chain of two pairs of complementary values: the chain gradually alternates between the opposite terminal states and the pattern is symmetrical. Such an existential plane catches an essential feature of Heraclitus’ philosophy, and can be illustrated by examples from classical Greek mythology. The same material also exemplifies Lévi-Strauss’ formula of myth, symmetrical in its weak and asymmetrical in 2 its canonical form. Since the weak form equals the orbit of a Klein group, we hypothesize that the canonical form, and thereby symmetry breaking, can be generated by element exchange between two respective Klein groups. The framework for such processes is text variation in folklore, described by ethnosemiotics.
