    A Multi-layered System Architecture for Environmental Monitoring Data Management – Taiwan’s Experience
    (Environmental Informatics and Systems Research, 2007) Chu, Yu-Chi
    This paper presents a comprehensive system architecture which adopts a multi-layer approach and is based on the web-based platform for environmental monitoring data management, ranging from data collection to applications. This architecture is designed in a modular and flexible fashion. As an example of practicality, the second phase Taiwan Air Quality Monitoring Network (TAQMN-2) has been implemented using the proposed system architecture to justify its feasibility. The overall structure of TAQMN-2 is described, and two major subsystems, data collection manager (DCM) and data access manager (DAM), are illustrated in detail. Taiwan EPA benefited greatly from the results of TAQMN-2, not only in terms of streamlining the air quality data management but also in upgrading work performance on improving the air quality in Taiwan. The usage of proposed architecture is not restricted to air quality data management; it is also suitable for other domains of environmental science with limited tuning, adjustments, or augmentation.

    An Ontology-Driven Approach for Harmonizing and Integrating Environmental Information
    (Environmental Informatics and Systems Research, 2007) Chu, Yu-Chi; Huang, Su-Mei; Lien, Chin-Cheng; Yang, Chen-Chau
    The paper describes an ontology-driven methodology to be used for the integration of heterogeneous environmental information that may be distributed in government agencies. The methodology adopts a series of systematic processes to construct a localized domain ontology which may be used as the driven force or guidelines for environmental information integration. As an example application, the Taiwan EPA’s Environmental Data Repository Project (EDR) is used to demonstrate the feasibility and applicability of the proposed methodology.

    Integrating Environmental Information through Data Warehousing with Data Quality Assurance
    (Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Chu, Yu-Chi; Young, Chea-Yuan; Yang, Chen-Chau
    This paper presents a comprehensive data warehouse framework for integrating environmental information. The proposed framework may serve as a platform and provide appropriate mechanisms for retrieving and gathering environmental data from various sources. For ensuring the quality of data in the environmental data warehouse, we introduce a four-phase process to ensure data quality while performing information integration. Overall data quality conditions can be identified and relevant information can be provided for determining whether the data meet “fit to use” criteria and whether they need to be improved. Accordingly, users may filter the data retrieved from the warehouse based upon various quality requirements.
