In the realm of Parkinson’s Disease (PD) research, the integration of wearable sensor data with personal health records (PHR) has emerged as a pivotal avenue for patient alerting and monitoring. This study delves into the complex domain of PD patient care, with a specific emphasis on harnessing the potential of wearable sensors to capture, represent and semantically analyze crucial movement data and knowledge. The primary objective is to enhance the assessment of PD patients by establishing a robust foundation for personalized health insights through the development of Personal Health Knowledge Graphs (PHKGs) and the employment of personal health Graph Neural Networks (PHGNNs) that utilize PHKGs. The objective is to formalize the representation of related integrated data, unified sensor and PHR data in higher levels of abstraction, i.e., in a PHKG, to facilitate interoperability and support rule-based high-level event recognition such as patient’s missing dose or falling. This paper, extending our previous related work, presents the Wear4PDmove ontology in detail and evaluates the ontology within the development of an experimental PHKG. Furthermore, this paper focuses on the integration and evaluation of PHKG within the implementation of a Graph Neural Network (GNN). This work emphasizes the importance of integrating PD-related data for monitoring and alerting patients with appropriate notifications. These notifications offer health experts precise and timely information for the continuous evaluation of personal health-related events, ultimately contributing to enhanced patient care and well-informed medical decision-making. Finally, the paper concludes by proposing a novel approach for integrating personal health KGs and GNNs for PD monitoring and alerting solutions. Full article

Intent classification is an essential task for goal-oriented dialogue systems for automatically identifying customers’ goals. Although intent classification performs well in general settings, domain-specific user goals can still present a challenge for this task. To address this challenge, we automatically generate knowledge graphs for targeted data sets to capture domain-specific knowledge and leverage embeddings trained on these knowledge graphs for the intent classification task. As existing knowledge graphs might not be suitable for a targeted domain of interest, our automatic generation of knowledge graphs can extract the semantic information of any domain, which can be incorporated within the classification process. We compare our results with state-of-the-art pre-trained sentence embeddings and our evaluation of three data sets shows improvement in the intent classification task in terms of precision.

Title: Intelligent text mining for ontological knowledge graph refinement and patent portfolio analysis - Case study of net-zero data center innovation management
Authors: Amy J.C. Trappey; Ging-Bin Lin; L.P. Hung
Affiliation: 1. Department of Industrial Engineering and Engineering Management, National Tsing Hua University, Hsinchu, Taiwan 2. Science & Technology Policy Research and Information Center, National Applied Research Laboratories, Taipei 106, Taiwan
Abstract: Ontological knowledge graph (OKG) is a well-formed visual representation that organizes and illustrates knowledge description in formal elements, such as entities, attributes, and interrelationships of elements. OKG is crucial for innovation management analysis as it provides a clear and comprehensive boundary to understand complex knowledge domain with detailed components and relationships. In the patent analysis field, it facilitates the definition of a well-defined patent portfolio, aiming for accurate and efficient patent retrievals and subsequent analyses. Recently, the rapid growth of the Information and Communication Technology (ICT) sector has rendered data centers (DCs) indispensable for data processing, storage, cloud computing, while ensuring security and privacy during DC operations. However, their energy-intensive operations pose challenges to global efforts toward achieving net-zero emissions goals. In response, this research develops a formal OKG refinement process and uses DC net-zero technology OKG as case study for its refinement and in-depth application in patent portfolio analysis. The net-zero DC domain covers five main sub-technologies. Utilizing the proposed OKG refinement and patent portfolio analysis framework, in the case study, 1,801 most recent decade’s patents related to relevant “DC net-zero technology” are retrieved and analyzed employing natural language processing (NLP) text mining methodologies for OKG refinement and detailed patent portfolio analysis, e.g., patent clustering, keyword identification, and patent semantic topic modeling. The domain OKG is refined, aiming to validate its effectiveness and accuracy in knowledge interpretation, organization, and applications iteratively. Furthermore, the research also applies technology function matrix (TFM) and technology maturity s-curve to assess the current and future development trends, patenting hotspots and opportunities, providing crucial references for forming R&D strategies and IP efforts.
