Inference with Distributional Semantic Models
Distributional Semantic Models have emerged as a strong theoretical and practical approach to model the meaning of words. Indeed, an increasing body of work has proved their value in accounting for a wide range of semantic phenomena. Yet, it is still unclear how we can use the semantic information …

The design and implementation of a language environment for evaluating the programming task
… is Pascal and its design is based on Johnston's semantic models of computation. Storage representations and implementation of these semantic models are described. These models depicting the compile-time structure, run-time structure, and realization of the static and the dynamic scoping rules. …

Interpretable semantic representations from neural language models and computer vision
… linguistics is dominated by high capacity neural models that in many cases outperform even human baselines on a wide variety of language-based tasks. However, a serious drawback to the development of these semantic models is in the ambiguity of these representations, as the dimensions of these …

Filter mediated design : generating coherence in (collaborative) design
… and topological database, from which multiple semantic models are constructed. Filter Mediated Design is intended to explore the processes and strategies of constructing intelligent designs and design intelligence.

A model for information retrieval driven by conceptual spaces
… is: what drives this transformation? For semantic information retrieval type of models this transformation is driven by the content and structure of the semantic models. In this case, Knowledge Organization Systems (KOSs) are the semantic models that encode the meaning employed for …

Models for Privacy in Ubiquitous Computing Environments
… to enforce. We show how quantitative trust models can be used to find trustworthy paths of communication and explore various semantic models of trust. For the unlinkability of a user's accesses to services in a ubiquitous computing environment, we present a model based on access control and …

GenoCAD: linguistic approaches to synthetic biology
… went beyond the syntactic level to explore the semantics of synthetic DNA sequences: by associating attributes with biological parts and coupling semantic actions with grammar rules, we developed the first semantic models to relate the genotype to the phenotype of synthetic genetic constructs. …

A Framework for Interoperability on the United States Electric Grid Infrastructure
… industries, along with utility industry-standard semantic models, to overcome information siloes and enable interoperability. By leveraging industrial engineering tools, a framework is also developed to help devise a reference architecture and use-case application process that is applied and …

Advancing semantic modeling: addressing coordination, interpretability, and data scarcity in domain representation
… from unorganized information. Traditional topic models provide a powerful framework for discovering latent themes but often fall short in practice: their outputs are generic and difficult to interpret, alignment across corpora is not guaranteed, and they struggle with both short documents and …

Semantic Processing of Digital Documents
… content-rich and well-structured document models are required for applications like verifying the consistency of documents. Creating such models for common documents is currently an expensive and error-prone process. In this thesis we present a novel approach to modelling and processing …

Semantic component selection
… The challenge is partially addressed by use of semantic models and reasoning approaches that allow categorisation and (within limited fashion) provide understanding of this information. Nevertheless, many such methods are dependent on expert input and, consequently, are expensive to produce and …

Semantic model and updated screening criteria for polymer flooding
… a specialized domain to the public. Therefore, semantic modeling techniques are applied to construct semantic models based on the relations among the major concepts and measuring data. The models will also be published as one part of an ambition to build a semantic knowledge repository for EOR …

A Novel Level-of-Detail Technique for Virtual City Environments: Design and Evaluation
… We begin with a VCE defined in existing semantic models such as the CityGML specification. We implement and evaluate a novel X3D-based Level-of-Detail technique called ProxyPrismLOD, which leverages the CityGML standard of a 4-step LOD hierarchy. For switching between different models of …

A BIM - GIS Integrated Information Model Using Semantic Web and RDF Graph Databases
… Building multi-sourced and multi-scale 3D urban models are in high demand among architects, engineers, and construction professionals to achieve these tasks and provide relevant information to decision support systems. Spatial modelling technologies such as Building Information Modelling (BIM) …

A Spinozan Analysis of Film Experience
… are largely compatible with George Lakoff’s semantic models, which focus on the experiential and embodied bases of cognition, and recent achievements within neurocognitive studies. With an innovative model that combines all these elements it is possible to accomplish a re-evaluation of …

Verbs as nouns: empirical investigations on event-denoting nominalizations
… usually perceived as alternatives, since their semantic difference is not clearly understood by neither native speakers nor linguists. The aim of this work is to understand the rationale that leads us to choose one form instead of the other and to define the linguistic features involved. The …

Shallow and deep learning for audio and natural language processing
… a large amount of training data. Deep learning models and kernel machines are regarded as models with high expressive power through the composition of multiple layers of nonlinearities and through nonlinearly mapping data to a high-dimensional space, respectively. While the majority of deep …

Transparent Analysis of Multi-Modal Embeddings
Vector Space Models of Distributional Semantics – or Embeddings – serve as useful statistical models of word meanings, which can be applied as proxies to learn about human concepts. One of their main benefits is that not only textual, but a wide range of data types can be mapped to a space, where …

New models and patterns for traceability
… The TRAceability Model (TRAM) consists of semantic models, designed using a layered approach, with each layer presenting traceability semantics from different user perspectives. The TRAceability Process (TRAP) consists of process models also utilising a layered approach but in this case …
