  2. 6. Rule extraction - the key to accurate and comprehensible data mining models

    Author : Ulf Johansson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Abstract : The primary goal of predictive modeling is to achieve high accuracy when the model is applied to novel data. For certain problems this requires the use of complex techniques, such as neural networks, resulting in opaque models that are hard or impossible to interpret. READ MORE

  4. 7. Best Trees Extraction and Contextual Grammars for Language Processing

    Author : Anna Jonsson; Johanna Björklund; Frank Drewes; Hendrik Jan Hoogeboom; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Weighted tree automata; the N-best problem; efficient algorithms; semantic graph; abstract meaning representation; contextual graph grammars; hyperedge replacement; graph extensions;

    Abstract : In natural language processing, the syntax of a sentence refers to the words used in the sentence, their grammatical role, and their order. Semantics concerns the concepts represented by the words in the sentence and their relations, i.e., the meaning of the sentence. READ MORE

  5. 8. Ontology Integration with Non-Violation Check and Context Extraction

    Author : Dan Wu; Anne Håkansson; Carl-Gustaf Jansson; Paul Johannesson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ontology matching and integration; semantic and pragmatic matching; semantic techniques; context; ontology and rules; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Abstract : Matching and integrating ontologies has been a desirable technique in areas such as data fusion, knowledge integration, the Semantic Web and the development of advanced services in distributed system. Unfortunately, the heterogeneities of ontologies cause big obstacles in the development of this technique. READ MORE

  6. 9. Mobility Knowledge Graph and its Application in Public Transport

    Author : Qi Zhang; Zhenliang Ma; Erik Jenelius; Carlos Lima Azevedo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Knowledge graph; Smart card data; Public transport; User-station attention; Relation extraction; Transportvetenskap; Transport Science; Transportsystem; Transport Systems;

    Abstract : Efficient public transport planning, operations, and control rely on a deep understanding of human mobility in urban areas. The availability of extensive and diverse mobility data sources, such as smart card data and GPS data, provides opportunities to quantitatively study individual behavior and collective mobility patterns.

  7. 10. Development and application of rule- and learning-based approaches within the scope of neuroimaging : Tensor voting, tractography and machine learning

    Author : Daniel Jörgens; Rodrigo Moreno; Örjan Smedby; Chunliang Wang; Jesper Andersson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tensor voting; tractography; deep learning; tractogram filtering; diffusion magnetic resonance imaging; tensorröstning; traktografi; djupinlärning; traktogramfiltrering; diffusions-MRT; Tillämpad medicinsk teknik; Applied Medical Technology;

    Abstract : The opportunity to non-invasively probe the structure and function of different parts of the human body makes medical imaging an indispensable tool in clinical diagnostics and related fields of research. Especially neuroscientists rely on modalities like structural or functional Magnetic Resonance Imaging, Computed Tomography or Positron Emission Tomography to study the human brain in vivo. READ MORE
