  1. 1. Interpretation and Alignment of 2D Indoor Maps Towards a Heterogeneous Map Representation

    University dissertation from Halmstad : Halmstad University Press

    Author : Saeed Gholami Shahbandi; Högskolan i Halmstad.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robotics; Mobile Robots; Autonomous Robots; Robot Perception; Robotic Mapping; Map Interpretation; Semantic Mapping; Place Categorization; Place Labeling; Semantic Annotation; Map Alignment; Region Segmentation; Region Decomposition; Map Representation; Heterogeneous Representation;

    Abstract : Mobile robots are increasingly being used in automation solutions with notable examples in service robots, such as home-care, and warehouses. Autonomy of mobile robots is particularly challenging, since their work space is not deterministic, known a priori, or fully predictable. READ MORE

  2. 2. Towards semantic language processing

    University dissertation from Umeå : Department of Computing Science, Umeå University

    Author : Anna Jonsson; Umeå universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Weighted tree automata; abstract meaning representation; contextual hyperedge replacement grammar; hyperedge replacement grammar; semantic modelling; the N best problem; Computer Science; datalogi; datorlingvistik; datorlingvistik;

    Abstract : The overall goal of the field of natural language processing is to facilitate the communication between humans and computers, and to help humans with natural language problems such as translation. In this thesis, we focus on semantic language processing. READ MORE

  3. 3. Multi-Document Summarization and Semantic Relatedness

    University dissertation from Umeå : Department of Computing Science, Umeå University

    Author : Olof Mogren; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; multi-document summarization; automatic summarization; semantic similarity; semantic relatedness;

    Abstract : Automatic summarization is the process of presenting the contents of written documents in a short, comprehensive fashion. Many approaches have been proposed for this problem, some of which extract content from the input documents (extractive methods), and others that generate the language in the summary based on some representation of the document contents (abstractive methods).

  4. 4. Semantic Mapping in Warehouses

    University dissertation from Halmstad University : Halmstad University Press

    Author : Saeed Gholami Shahbandi; Högskolan i Halmstad.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automation; Robotics; Mapping; Semantic Maps; Warehouse Automation;

    Abstract : This thesis and appended papers present the process of tacking the problem of environment modeling for autonomous agent. More specifically, the focus of the work has been semantic mapping of warehouses. A semantic map for such purpose is expected to be layout-like and support semantics of both open spaces and infrastructure of the environment. READ MORE

  5. 5. Bridging the Semantic Gap between Sensor Data and Ontological Knowledge

    University dissertation from Örebro : Örebro university

    Author : Marjan Alirezaie; Örebro universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Semantic Gap; Ontology; Knowledge Representation and Reasoning; Sensor Data; Informatik; Informatics;

    Abstract : The rapid growth of sensor data can potentially enable a better awareness of the environment for humans. In this regard, interpretation of data needs to be human-understandable. For this, data interpretation may include semantic annotations that hold the meaning of numeric data. READ MORE
