EUROCAST (1) - Adaptive change estimation in the context of online Market Monitoring
Computer Aided Systems Theory – EUROCAST 2011, 2012Co-Authors: Norbert Walchhofer, Karl Anton Froeschl, Kurt HornikAbstract:In the Internet-based economy, the (relative) transparency of e-Markets and increasing online Market dynamics call for more responsive and encompassing approaches towards the Monitoring of Markets and competitors. Accordingly, this paper proposes to observe continuously a preselected set of e-commerce Web channels, or online portals, to gather a comprehensive as possible picture of Market dynamics. In so doing, a historical Market data repository is accumulated based on an adaptive scheme of harvesting Web data online in order to provide dynamic information about both Market structure and prices. A description of the proposed estimator for online data sampling based on observed (price) change frequencies is given. Numerical simulations highlight the virtues of the proposed adaptive estimator compared to established Web page change frequency estimators, even more so in case of considering constraints on (observation) resources. As an example, the methodology is applied to the online hotel room booking Market.

Dynamic Population Segmentation in Online Market Monitoring
Studies in Classification Data Analysis and Knowledge Organization, 2010Co-Authors: Norbert Walchhofer, Milan Hronský, Karl Anton Froeschl, Kurt HornikAbstract:The objective of the SEMAMO (Semantic Market Monitoring) project is to make use of the increasingly growing information available at Web-based sales and Marketing channels for Market research, using semi-automatic analysis driven by application domain models. The assumptions are that (i) the Web may serve as a representative “picture” of reality, (ii) the respective online channels map salient Market developments, and (iii) all of this accurately and in a timely manner. Limited server requests and Market specific access structures of Web portals inhibit both full scans of sampling populations and random selection of sampled offers. Further, product feature categories entail multiple classifications within offer clusters (e.g., geography in tourism). Therefore, SEMAMO proposes an adaptive sampling strategy dealing simultaneously with (i) the dynamics of the population frame, (ii) price dynamics, and (iii) multiple (fuzzy) classifications of offered products. The paper discusses a heuristic method of dynamically segmenting monitored offer populations to stratify online data harvesting depending on both observed price changes and information relevance, and outlines the mechanics of harvest schedule derivation.

ENTER - Semantic Online Tourism Market Monitoring
Information and Communication Technologies in Tourism 2010, 2010Co-Authors: Norbert Walchhofer, Milan Hronský, Michael Pöttler, Robert Baumgartner, Karl Anton FröschlAbstract:SEMAMO (SEmantic Market Monitoring) is a research project seeking to make use of the increasingly growing information available at Web-based sales and Marketing channels for continuous Market research. Assuming that online channels indeed mirror salient Market developments faithfully, SEMAMO implements a nearly fully automatic adaptive data capture and analysis process delivering customer-defined Market reports on demand. The paper describes the SEMAMO prototype implementation and exemplifies the functionality and utility of the approach in the domain of e-tourism, with a focus on the type of reports and visualisations the software, albeit not completely finished yet, can already deliver based on real-world data. Additionally, the role of formal domain description in SEMAMO is emphasized.

an approach for post Market Monitoring of potential environmental effects of bt maize expressing cry1ab on natural enemies
Journal of Applied Entomology, 2009Co-Authors: Olivier Sanvido, Jörg Romeis, F. BiglerAbstract:Post-Market Monitoring (PMM) consistent with Swiss and European Union legislation should ensure the detection and prevention of adverse effects on the environment possibly deriving from commercial cultivation of genetically modified (GM) crops. Insect-resistant GM crops (such as Bt-maize) raise particular questions regarding disturbances of biological control functions provided by beneficial insects such as predators and parasitoids (so-called natural enemies). Consensus among regulators, scientists and the agricultural biotech industry on appropriate PMM plans allowing the detection and possibly prevention of such adverse effects is still lacking. The aims of this study were to identify the necessity for PMM of Bt-maize expressing Cry1Ab on natural enemies and to develop an appropriate PMM plan. The approach chosen consisted in determining what type of Monitoring is most appropriate to address potential effects of Bt-maize on natural enemies during commercial cultivation. This included identifying whether there remain substantial scientific uncertainties that would support case-specific Monitoring. Existing pre-Market risk assessment data indicate that Bt-maize (Cry1Ab) comprises a negligible risk for disturbances in biological control functions of natural enemies. As a consequence, a faunistic Monitoring of specific groups of natural enemies is not considered an appropriate approach to detect failures in biological control functions. Alternatively, an approach is proposed that consists in indirectly analysing biological control functions by surveying outbreaks of maize herbivores. Unusual herbivore outbreaks could indicate failures in biological control functions of natural enemies. Data could be collected via questionnaires addressed to farmers growing Bt-maize. Significant correlations between unusual occurrences of specific maize herbivores and the cultivation of Bt-maize would subsequently need specific studies to determine possible causalities in more detail. The here proposed approach has the advantage of covering different natural enemy groups. It represents a cost-effective strategy to obtain scientifically sound data as a basis for regulatory decision-making.

A framework for the design of general surveillance of genetically modified crops based on a concept for environmental post-Market Monitoring
Journal für Verbraucherschutz und Lebensmittelsicherheit, 2006Co-Authors: Olivier Sanvido, M Winzeler, Franco Widmer, Franz BiglerAbstract:A framework for the design of general surveillance during commercial cultivation of genetically modified (GM) crops according to current EU legislation 2001/18/EC is presented. The framework is based on a previously established concept for environmental post-Market Monitoring (PMM), which identified clear conceptual differences between case-specific Monitoring (CSM) and general surveillance. While CSM focuses on anticipated effects of a specific GM crop, general surveillance is designed to detect unanticipated effects on the environment. Two separate frameworks are proposed for developing either of the two programmes. Considering its focus, general surveillance has to be based both on the subjects of environmental concern (safeguard subjects) that should not be adversely affected by GM crop cultivation and on the environmental quality that should be preserved therein. Unanticipated effects in the defined safeguard subjects may be detectable by using existing Monitoring networks and by establishing appropriate reporting systems. Results from general surveillance can, however, not be linked to any specific attribute of GM crop cultivation, and causality to environmental damages will have to be determined via specific risk assessement studies. The proposed structure for general surveillance represents a pragmatic approach to a realistic and feasible PMM programme and will be of assistance to industry, researchers, and regulators when assessing GM crops during commercialisation.

a conceptual framework for the design of environmental post Market Monitoring of genetically modified plants
Environmental Biosafety Research, 2005Co-Authors: Olivier Sanvido, M Winzeler, Franco Widmer, Franz BiglerAbstract:Genetically modified plants (GMPs) may soon be cultivated commercially in several member countries of the European Union (EU). According to EU Directive 2001/18/EC, post-Market Monitoring (PMM) for commercial GMP cultivation must be implemented, in order to detect and prevent adverse effects on human health and the environment. However, no general PMM strategies for GMP cultivation have been established so far. We present a conceptual framework for the design of environmental PMM for GMP cultivation based on current EU legislation and common risk analysis procedures. We have established a comprehensive structure of the GMP approval process, consisting of pre-Market risk assessment (PMRA) as well as PMM. Both programs can be distinguished conceptually due to principles inherent to risk analysis procedures. The design of PMM programs should take into account the knowledge gained during approval for commercialization of a specific GMP and the decisions made in the environmental risk assessments (ERAs). PMM is composed of case-specific Monitoring (CSM) and general surveillance. CSM focuses on anticipated effects of a specific GMP. Selection of case-specific indicators for detection of ecological exposure and effects, as well as definition of effect sizes, are important for CSM. General surveillance is designed to detect unanticipated effects on general safeguard subjects, such as natural resources, which must not be adversely affected by human activities like GMP cultivation. We have identified clear conceptual differences between CSM and general surveillance, and propose to adopt separate frameworks when developing either of the two programs. Common to both programs is the need to put a value on possible ecological effects of GMP cultivation. The structure of PMM presented here will be of assistance to industry, researchers, and regulators, when assessing GMPs during commercialization.

Market Monitoring and control of ancillary services
Decision Support Systems, 2001Co-Authors: Ali Keyhani, Ashkan Rahimi Kian, Jose B. Cruz, Marwan A. SimaanAbstract:Abstract In this paper, the problems of Market Monitoring and control of ancillary services of future energy systems are presented. We envision that future system operation of electric power systems will evolve into completely unbundled ancillary service Markets that are governed by spot price signals. The grid operators need to acquire ancillary services through competitive Markets for control of the system operation. With the above vision of the future, this paper presents the control of ancillary services based on a frequency regulation/load following (LFC) Market, a load regulating (RL) Market, and a base load (BL) Market. In the LFC Market, the units dispatched for generation must have specific response characteristics as determined by the nature of system loads. These units will be controlled by the grid operator. It is envisioned that LFC will be multi-time scale and decentralized. In the RL Market, the units dispatched for generation will not participate in LFC. These units are dispatched for specific period of time for regulating system load. The BL units are dispatched daily to satisfy the BL of the day on a weekly or monthly basis. The locational Market power associated with generators participating in LFC and in RL is even more critical than that for generators participating in satisfying the BL, since these units are required for frequency regulation, voltage support and relief of overload conditions. To create an efficient Market for these services, we will propose and formulate the use of incentive strategies for the BL, RL and the LFC Markets.
