Finding analogies in semantic networks using the singular value decomposition
… algorithm for finding analogies in large, sparse semantic networks. We treat analogies as comparisons between domains of knowledge. A domain is a small semantic network, i.e., a set of concepts and binary relations between concepts. We treat our knowledge base (the large semantic network) as if it …

Real time safety verification in the process industry using fault semantic networks (FSN)
In the process industry, there are uncertainties associated with each variable, which might lead to process deviations and hazards. In order to accurately quantify the risks associated with these hazard scenarios, quantitative probability should be calculated. The process dynamically changes during …

Uncovering Dynamic Semantic Networks in the Brain Using Novel Approaches for EEG/MEG Connectome Reconstruction
… unresolved predictions of recent models of the semantic brain system, such as the hub-and-spokes model. In particular, we tackle different aspects of the hypothesis that a widespread network of interacting heteromodal (hub(s)) and unimodal (spokes) cortices underlie semantic cognition. For this …

Conceptos relacionados con estrella. Lingüística de corpus de astronomía
… and relations are then used to build the semantic networks enriched with the previously detected information. The research concludes the need of: removing all functional words; unifying synonyms spellings only for words which are in the high and medium intervals; not removing the …

A structural framework for assembly modeling and recognition
… classes of mechanical assemblies. Implemented as semantic networks and applying parsing strategies known from discourse theory, they enable the flexible detection of arbitrary assembly structures in image data. Graph-based models are derived from syntactic structures and subsequent graph matching …

Systems analysis of vaccination in the United States: Socio-behavioral dynamics, sentiment, effectiveness and efficiency
… on social media by constructing and analyzing semantic networks of vaccine information online. Finally, we estimate the health benefits, costs, and cost-effectiveness of influenza vaccination strategies in Seattle using a dynamic agent-based model. The underlying motivation for this research is …

Aspects of cognition in human mate selection
… type on reaction time (ms) was found. Finally, semantic networks generated by the Pathfinder algorithm revealed that men and women associated concepts into meanings about human mating in a way that partially supported evolutionary predictions.

The discourse model for collaborative design: A distributed and asynchronous approach
… workspace that incorporates frames, constraints, semantic networks, libraries of sharable design objects, software agent modules, an electronic messaging system, and a Virtual Workspace Language based in part on Knowledge Query Manipulation Language (KQML). Components of the process include …

Collocation and preposition sense: a phraseological approach to the cognition of polysemy
… to into and through to reinforce and amend the semantic networks for these prepositions proposed by Lakoff and by Tylor and Evans.

Deep Learning of Semantic Image Labels on HDR Imagery in a Maritime Environment
… High-Dynamic Range imagery for deep learning of semantic image labels is studied in a littoral environment. This study theorizes that the use HDR imagery may be extremely beneficial for the purpose of situational awareness in maritime environments due to the inherent advantages of the technology. …

An object-oriented database system for efficient information retrieval applications
… as a graph, such as a thesaurus encoded in semantic networks, or hypertext collections. Even traditional IR models can use graph representations of documents and concepts. This dissertation reports the development of an object-oriented model called the LEND (Large External object-oriented …

Effects of Language Dominance in Spanish-English Bilingual Speakers
… little attention. This study examines the semantic networks of Spanish-English bilingual adults and monolingual English-speaking peers to determine whether language dominance structures the semantic space of a bilingual speaker to more closely match the semantic space of a monolingual …

Designing end user information environments built on semistructured data models
… of our semistructured data model (based on semantic networks) and explore its consequences to the user interface, a system named Haystack has been built that permits users to store their information in a flexible fashion that can adapt to their needs.

Knowledge Graph Extension by Entity Type Recognition
… as a sophisticated advancement and refinement of semantic networks, and their deployment is one of the critical methodologies in contemporary artificial intelligence. The construction of knowledge graphs is a multifaceted process involving various techniques, where researchers aim to extract the …

An architectural selection framework for data fusion in sensor platforms
… of fusion to the concept and operation of the Semantic Web, which promises new ways to exploit the synergy of multi-sensor data platforms. This requires the synthesis of fusion with ontology models for knowledge representation. We discuss the importance of fusion as a reuse process in …

Rational Creatures: Using Vector Space Models to Examine Independence in the Novels of Jane Austen, Maria Edgeworth, and Sydney Owenson (1800–1820)
… applies word-context models (word embeddings and semantic networks) to the novels of Austen, Edgeworth, and Owenson. This study, therefore, seeks to evaluate the use of vector space models when applied to these novels. This research first defines a theoretical framework - enhanced reading - which …
