- KonferenzbeitragInformation System on Literature in the Field of ICT for Environmental Sustainability(Integration of Environmental Information in Europe, 2010) Lutz, Richard; Geiger, Werner; Schmitt, Christian; Schreiber, MartinThe project ICT-ENSURE aims at building a pan-European Research Area in the field of ICT for environmental sustainability. For building up and establishing a research area, the access to the hitherto existing scientific literature in the field is of major importance. Therefore, a literature information system for the field of ICT for environmental sustainability has been developed within ICT-ENSURE. The system developed contains information on the papers of 14 EnviroInfo conferences and of 4 further conferences and workshops in the field under consideration. All in all, it comprises the metadata of about 1600 and the full texts of about 1000 articles. The information system offers various search and navigation paths to this content, including full text search, attribute search and navigation in the hierarchical structure of the conference proceedings. It is available in the Web at http://lit.ict-ensure.eu with free online access. This paper describes the concept, structure and functionality of the information system including the interfaces to other literature portals. It deals with the contents and user interface of the system and gives an outlook on the future of the information service.

- KonferenzbeitragManaging LCI Data from Different Workgroups within the same Instance of an LCA Database(EnviroInfo Dessau 2012, Part 2: Open Data and Industrial Ecological Management, 2012) Düpmeier, Clemens; Greceanu, Claudia; Kusche, Oliver; Schmitt, ChristianLife Cycle Thinking (LCT) and Life Cycle Assessment (LCA) are the scientific approaches behind modern environmental policies and business decision support related to Sustainable Consumption and Production. For the efficient and reliable application of LCA, it is necessary that LCA studies are based on consistent, transparent, and qualityassured Life Cycle Inventory (LCI) data. To manage and provide such consistent and quality assured Life Cycle data to users the Institute of Applied Computer Science of the Karlsruhe Institute of Technology developed an open source service oriented LCA database software (soda4LCA) that can be accessed directly from within LCA tools to store, manage and extract LCA datasets via the Internet. Different soda4LCA instances can even be connected together via the Internet to form a LCA data network which can then be used by users via one of the network nodes. Because of user requirements, the storage model of soda4LCA is enhanced in the current development version to support the management of largely separated collections of datasets (called data stocks) by different working groups. This can be seen as a first step to support multitenancy in soda4LCA. It’s also possible in the current development version to build other logical collections of datasets for such use cases as compiling collections of datasets for review or release management. Data stocks are also the key element of soda4LCA to provide dataset replication via nodes of a soda4LCA data network. Further details of the data stock concept and its usages will be described in the following chapters.

- KonferenzbeitragSuchmaschinen-getriebene Umweltportale – Nutzung einer ElasticSearch-Suchmaschine(Umweltinformationssysteme. Big Data – Open Data – Data Variety, 2015) Schlachter, Thorsten; Düpmeier, Clemens; Schmitt, Christian; Schillinger, WolfgangIn order to merge data from different information systems in web portals, querying of this data has to be simple and with good performance. If no direct, high-performance query services are available, data access can be provided (and often accelerated) using external search indexes, which is well-proven for unstructured data by means of classical full text search engines. This article describes how structured data can be provided through search engines, too, and how this data then can be re-used by other applications, e.g., mobile apps or business applications, incidentally reducing their complexity and the number of required interfaces. Users of environmental portals and applications can benefit from an integrated view on unstructured as well as on structured data.
- KonferenzbeitragTechnisches Konzept der Forschungsinformationssysteme des EU-Projekts ICT-ENSURE(Datenanforderungen und Informationsgewinnung zum Themenbereich Umwelt und Gesundheit, 2010) Lutz, Richard; Schmitt, Christian; Geiger, WernerMit dem EU-Projekt ICT-ENSURE (European Information and Communication Technologies - Environmental Sustainability Research) soll die Etablierung einer europaweiten Forschungslandschaft im Bereich ICT für Nachhaltigkeit in der Umwelt unterstützt werden (Tochtermann et al., 2008). Ein Schwerpunkt der Arbeiten bildet die Entwicklung eines web-basierten Informationssystems über nationale europäische Forschungsprogramme und -projekte sowie die Online-Bereitstellung von Literatur im genannten Bereich in Form eines Literatur-Informationssystems. Beide Systeme dienen Programm- und Projektleitern, Wissenschaftlern und forschungspolitischen Entscheidungsträgern als Informationsplattform über laufende und durchgeführte Forschungsprogramme und -projekte im genannten Bereich (Lutz et al., 2009, Geiger et al., 2009). Der Beitrag beschreibt die Anforderungen an die Systeme, deren Architektur und die zu Grunde liegenden Datenmodelle, die Implementierung der Systeme sowie deren Funktionalität. Die beiden Informationssysteme sind über http://is.ict-ensure.eu bzw. http://lit.ict-ensure.eu zu erreichen.
- KonferenzbeitragThe ICT-ENSURE Information System on National Research Programmes in EU Member States(Environmental Informatics and Industrial Environmental Protection: Concepts, Methods and Tools, 2009) Lutz, Richard; Schmitt, Christian; Geiger, WernerThe ICT-ENSURE project has been launched to establish a European Research Area (ERA) in the field of ICT for environmental sustainability. Within the framework of this project funded under the 7th Research Framework Programme of the European Union (FP7), a web-based information system on national research programmes in the field of ICT for environmental sustainability is being developed to enhance the exchange of information on research programmes and research results in Europe. This paper shall outline the objectives and features of the information system on research programmes developed under the ICT-ENSURE project.
- KonferenzbeitragThe MAUT-Machine: An Adaptive Recommender System(10. GI-Workshop "Adaptivität und Benutzermodellierung in interaktiven Softwaresystemen", 2002) Schmitt, Christian; Dengler, Dietmar; Bauer, MathiasIn this paper we introduce an adaptive recommender system that supports the user in finding interesting entries in an electronic product catalog. The Analytic Hierarchy Process (AHP) lays the foundation for the user preferences. The user interests are specified in terms of desired properties of the ideal product, expressed in the form of constraints (or criteria) on the products basic attributes. Logically related criteria can be combined to form a criteria tree and weights are used to specify the relative importance of these criteria (their contribution impact on the overall rating). An extension of the Multi-Attribute Utility Theory (MAUT) that allows complex and powerful combinations of criteria is used to compute the degree of interest (or utility) of the products regarding the user preferences. Once the user has defined her preferences she can quickly identify the most promising products in the treemaps display of the catalogue, colour-coding schemes indicating the different degrees of interest and the user having the possibility to sort the catalogue by several of its products basic attributes. The user profile and the catalogue are simultaneously visible and each modification of her preferences is immediately mirrored in the treemaps display that always presents the quality of the catalogue entries w.r.t. the current user preferences. The user can also select a given criteria node in her preferences and see the performance of the catalogue entries for that criteria. This way, rational decision making with multi-criteria objectives is significantly alleviated.
