Traditional knowledge acquisition methods have been proved costly, resource intensive and time consuming. Automation of large scale knowledge acquisition systems requires narrowing down the semantic gap between biomedical texts and structured representations. In this context, this study proposes a knowledge acquisition framework from biomedical texts. This contributes towards reducing efforts, time and cost incurred to minimaize ontology acquisition bottlenecks. The proposed framework approximates, models, structures and ontologizes implicit knowledge buried in biomedical texts. In the framework, the semantic disambiguator approximates biomedical artefacts from biomedical texts. The conceptual disambiguator models and structures the biomedical knowledge abstracted from the domain texts. Ontologization presents an explicit interpretation of biomedical artefacts and conceptualizations. The components of the framework are instantiated with scientific and clinical text documents and produced about four million concepts and seven million associations. This set of artefacts is structured into the lower ontological knowledge structure where the upper ontology structure is reused from existing ones. The conceptual structure is represented with graph formalism. The formal interpretation is based on OWL DL language primitives and constructs, which generates a set of OWL DL axioms. The set of OWL DL axioms is referred as the OWL ontology ( K o ). The extent of approximation and quality of structural design are evaluated using criteria-based methods. A set of metrics is used to measure each criterion and showed encouraging results. Correctness measurements for concept entity are 70% for accuracy, 82% for completeness, 68% for conciseness and 100% for consistency. Quality measurement showed complex ontology structure with metrics values of 986,448 for vocabulary size, 18.73 for connectivity density, 145,246 for tree impurity and 226, 698 for graph entropy. The ontology schema potential metrics values are also 0.80 for relationship richness, 3 for attribute richness and 13,253 for inheritance richness. Ontology clarity showed an average readability, which is 3 attributes on average. The proposed framework has limitations to address the acquisition of individuals and entity attributes, losing cardinality information in the acquisition of the ontological knowledge. These lead to limitations on the formal interpretation of biomedical semantics, which in turn lead to deploy only existential restriction based interpretations. Thus, a way forward has been recommended to enhance semantic disambiguation and ontologization of the proposed framework so that they enable to accommodate the acquisition of cardinality and attribute information.

Section 1 of the entry outlines the working definition of semantic related- ness and its applications and challenges. Section 2 identifies the knowledge resources that are popular among semantic relatedness methods. Section 3 reviews the primary measurements used to calculate semantic relatedness. Section 4 reviews the evaluation methodology which includes gold standard dataset and methods. Finally, Section 5 in- troduces further reading. In order to develop appropriate semantic relatedness methods, there are three key aspects that need to be examined: 1) the knowledge resources that are used as the source for extracting semantic relatedness; 2) the methods that are used to quantify semantic relatedness based on the adopted knowledge resource; and 3) the datasets and methods that are used for evaluating semantic relatedness techniques. The first aspect involves the selection of knowledge bases such as WordNet or Wikipedia. Each knowledge base has its merits and downsides which can directly affect the accurarcy and the coverage of the semantic relatedness method. The second aspect relies on different methods for utilizing the beforehand selected knowledge resources, for example, methods that depend on the path between two words, or a vector representation of the word.

  • Theory-Based Knowledge Acquisition for Ontology Development
    UNIVERSITÄT HOHENHEIM Theory-based Knowledge Acquisition for Ontology Development A dissertation submitted to the Faculty of Business, Economics and Social Sciences of the University of Hohenheim in partial fulfillment of the requirements for the degree of Doctor of Economics (Dr. oec.) by Andreas Scheuermann July 2016 Principal advisor: Prof. Dr. Stefan Kirn Co-advisor: Prof. Dr. Ralph Bergmann Chair of the examination committee: Prof. Dr. Christian Ernst Dean: Prof. Dr. Dirk Hachmeister Date of oral examination: 7. July 2016 Abstract iii Abstract This thesis concerns the problem of knowledge acquisition in ontology development. Knowledge acquisition is essential for developing useful ontologies but it is a complex and error-prone task. When capturing specific knowledge about a particular domain of interest, the problem of knowledge acquisition occurs due to linguistic, cognitive, modelling, and methodical difficulties. For overcoming these four difficulties, this research proposes a theory-based knowledge acquisition method. By studying the knowledge base, basic terms and concepts in the areas of ontology, ontology development, and knowledge acquisition are defined. A theoretical analysis of knowledge acquisition identifies linguistic, cognitive, modelling, and methodical difficulties, for which a survey of 15 domain ontologies provides further empirical evidence. A review of existing knowledge acquisition approaches shows their insufficiencies for reducing the problem of knowledge acquisition. As the underpinning example, a description of the domain of transport chains is provided. Correspondingly, a theory in business economics, i.e. the Contingency Approach, is selected. This theory provides the key constructs, relationships, and dependencies that can guide knowledge acquisition in the business domain and, thus, theoretically substantiate knowledge acquisition.

Wikipedia is the largest collaborative encyclopedia and is used as the source for DBpedia, a central dataset of the LOD cloud.

The DBpedia In- formation Extraction Framework transforms semi-structured data from Wikipedia into structured RDF.

This talk sketches the main themes of AI and machine learning, tracing the evolution of the field since its beginning in the 1950s and explaining some of its main concepts. These eras are characterized as “from knowledge is power” to “data is king”. • Digital Readiness: AI/ML, Finding a doing machine. – In the last decade Machine Learning had a remarkable success record. We will review reasons for that success, review the technology, examine areas of need and explore what happened to the rest of AI, GOFAI (Good Old Fashion AI). • Digital Readiness: AI/ML, Common Sense prevails? – Will there be another AI Winter? We will explore some clues to where the current AI/ML may reunite with GOFAI (Good Old Fashioned AI) and hopefully expand the utility of both. This will include extrapolating on the necessary melding of AI with engineering, particularly systems engineering.

    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Repository of the Academy's Library CONCEPTUALIZATION AND VISUAL KNOWLEDGE ORGANIZATION: A SURVEY OF ONTOLOGY-BASED SOLUTIONS A. Benedek1, G. Lajos2 1 Hungarian Academy of Sciences (HUNGARY) 2 WikiNizer (UNITED KINGDOM) Abstract Conceptualization and Visual Knowledge Organization are overlapping research areas of Intellect Augmentation with hot topics at their intersection which are enhanced by proliferating issues of ontology integration. Knowledge organization is more closely related to the content of concepts and to the actual knowledge items than taxonomic structures and ‘ontologies’ understood as “explicit specifications of a conceptualization” (Gruber). Yet, the alignment of the structure and relationship of knowledge items of a domain of interest require similar operations. We reconsider ontology-based approaches to collaborative conceptualization from the point of view of user interaction in the context of augmented visual knowledge organization. After considering several formal ontology based approaches, it is argued that co-evolving visualization of concepts are needed both at the object and meta-level to handle the social aspects of learning and knowledge work in the framework of an Exploratory Epistemology. Current systems tend to separate the conceptual level from the content, and the context of logical understanding from the intent and use of concepts. Besides, they usually consider the unification of individual contributions in a ubiquitous global representation. As opposed to this God's eye view we are exploring new alternatives that aim to provide Morphic-like live, tinkerable, in situ approaches to conceptualization and its visualization and to direct manipulation based ontology authoring capabilities.
