This volume contains the proceedings of the 1st Workshop on Computing News Storylines (CNewsStory 2015) held in conjunction with the 53rd Annual Meeting of the Association for Computational Linguistics and the 7th International Joint Conference on Natural Language Processing (ACL-IJCNLP 2015) at the China National Convention Center in Beijing, on July 31st 2015. Narratives are at the heart of information sharing. Ever since people began to share their experiences, they have connected them to form narratives. The study od storytelling and the field of literary theory called narratology have developed complex frameworks and models related to various aspects of narrative such as plots structures, narrative embeddings, characters’ perspectives, reader response, point of view, narrative voice, narrative goals, and many others. These notions from narratology have been applied mainly in Artificial Intelligence and to model formal semantic approaches to narratives (e.g. Plot Units developed by Lehnert (1981)). In recent years, computational narratology has qualified as an autonomous field of study and research. Narrative has been the focus of a number of workshops and conferences (AAAI Symposia, Interactive Storytelling Conference (ICIDS)...

New Intelligent Transport System (ITS) applications such as the Digital Tachograph (DT) require reliable Global Navigation Satellite System (GNSS) signal reception to perform their activities. However, communication and navigation signal reception is vulnerable to several forms of interference such as brute-force jamming. In this case, powerful signals are broadcast in the frequency bands used by the victim receiver. In this way, the receiver is unable to operate having a cascade effects on ITS applications. A solution against jamming is the development of pre-correlation techniques which exploit the Interference Cancellation (IC) principle. In this paper, a real-time Software Defined Radio (SDR) platform able to mitigate the impact of jamming is developed. The platform is fully reconfigurable and implements several mitigation techniques such as notch filtering and pulse blanking. The tests performed using a real GNSS jammer show that the platform developed is an effective solution which can be easily applied to the road transportation sector.; JRC.G.6-Digital Citizen Security

The Threshold of Toxicological Concern (TTC) concept is well established for assessing human safety of indirect food additives and has been reapplied for a variety of endpoints including carcinogenicity, teratogenicity, and reproductive toxicity. TTC approaches have benefits for screening-level risk assessments, including the potential for rapid decision-making, fully utilizing existing knowledge, reasonable conservativeness for chemicals used in lower volumes (Low Production Volume Chemicals (LPCVs – e.g. < 1 t/yr), and reduction or elimination of unnecessary animal tests. Higher Production Volume Chemicals (HPVCs - > 1t/yr) would in principle always require specific information. TTC has found particular favor in the assessment of chemicals used in cosmetics and personal care products as well as other chemicals traditionally used in low volumes. Use of the TTC in environmental safety is just beginning and initial attempts are being published. Key questions focus on hazard extrapolation of diverse taxa across trophic levels, importance of mode of action, and whether safe concentrations for ecosystems estimated from acute or chronic toxicity data are equally useful and in what contexts. This paper will provide an overview of the theoretical basis for developing an eco-TTC with an initial exploration for chemical assessment and boundary conditions for use. An international collaboration under the ILSI Health and Environmental Sciences Institute has been established to address challenges related to developing and applying useful eco-TTC concepts.; JRC.I.5-Systems Toxicology

We analyze the evolution of beer consumption between countries and over time. Historically, there have been major changes in beer consumption in the world. In recent times, per capita consumption has decreased in traditional beer drinking countries while it increased strongly in emerging economies. Recently, China has overtaken the US as the largest beer economy. A quantitative empirical analysis studies the relation between economic growth, globalization and beer consumption. The relationship between income and beer consumption has an inverse U-shape. Beer consumption initially increases with rising incomes; but at higher levels of income beer consumption falls. Increased globalization has contributed to a convergence in alcohol consumption patterns across countries. In countries that were originally beer drinking countries, the share of beer in total alcohol consumption reduced, while this is not the case in countries which traditionally drank mostly wine or spirits.; JRC.J.4-Agriculture and Life Sciences in the Economy

While natural intoxications with seeds of Ricinus communis have long been known, the toxic protein ricin contained in the seeds is of major concern due to its history of criminal, terrorist and military use. In order to harmonize detection capabilities in expert laboratories an international proficiency test was organized that aimed at identifying good analytical practices (qualitative measurements) and determining a consensus concentration on a highly pure ricin reference material (quantitative measurements). Sample materials included highly pure ricin as well as the related R. communis agglutinin spiked into buffer, milk and meat extract; additionally, an organic fertilizer naturally contaminated with R. communis shred was investigated in the proficiency test. The qualitative results showed that either a suitable combination of immunological, MS-based and functional approaches or sophisticated MS-based approaches alone successfully allowed to detect and identify ricin in all samples. In terms of quantification, it was possible to determine a consensus concentration for the highly pure ricin reference material. The results provide a basis for further steps in quality assurance and improve biopreparedness in expert laboratories worldwide.; JRC.D.2-Standards for Innovation and sustainable Development

In the framework of the EU project EQuATox a first international proficiency test (PT) on the detection and quantification of BoNT was conducted. Sample materials included BoNT serotypes A, B and E spiked into buffer, milk, meat extract and serum. A variety of methods was applied by the participants combining different principles of detection, identification and quantification. Based on qualitative assays, 95% of all results reported were correct. Successful strategies for BoNT detection were based on a combination of complementary immunological, MS-based and functional methods or on suitable functional in vivo / in vitro approaches (mouse bioassay, hemidiaphrama assay, Endopep-MS assay). Quantification of BoNT/A, BoNT/B and BoNT/E was performed by 48% of participating laboratories. It turned out that precise quantification of BoNT was difficult resulting in a substantial scatter of quantitative data. This was especially true for results obtained by the mouse bioassay which is currently seen as “gold standard” for BoNT detection. The results clearly demonstrate the urgent need of certified BoNT reference materials and the development of methods replacing animal testing. In this context, the BoNT PT provided the valuable information that both the Endopep-MS assay and the hemidiaphrama assay delivered quantitative results superior to the mouse bioassay.; JRC.D.2-Standards for Innovation and sustainable Development

This report presents the results of the sixteenth inter-laboratory comparison (ILC) organised by the European Union Reference Laboratory for Polycyclic Aromatic Hydrocarbons (EURL PAH) on the determination of the four EU marker PAHs, benz[a]anthracene (BAA), benzo[a]pyrene (BAP), benzo[b]fluoranthene (BBF) and chrysene (CHR) in smoked fish. Both officially nominated National Reference Laboratories (NRLs) and official food control laboratories (OCLs) of the EU Member States participated. In agreement with National Reference Laboratories, the test material used in this exercise was smoked herring. Participants also received a solution of PAHs in solvent of their choice (either toluene or acetonitrile) with known content for the verification of their instrument calibration. . The participants were free to choose the method of analysis. Reference values were used to benchmark the results reported by participants. The performance of the participating laboratories in the determination of the target PAHs in smoked fish was expressed by z-scores. Satisfactory performance with regard to z-scores was assigned to about 83 % of the reported results. JRC-IRMM is an ISO/IEC 17043 accredited provider of proficiency testing schemes and the respective rules were applied during all phases of this PT.; JRC.D.5-Standards for Food Bioscience

This paper summarizes the results of the through-thickness residual stress distributions on dissimilar metal weld (DMW) mock-up. DMWs, as welded joints between ferritic steels and either austenitic stainless steels or nickel-based alloys, are commonly found in piping systems of NPPs as well as in other industrial plants. The welding of the mock-up is simulated by the 3D finite element model using temperature and phase dependent material properties. The commercial finite element code MSC.Marc is used to obtain the numerical results by implementing the Goldak’s double ellipsoidal shaped weld heat source and combined convection radiation boundary conditions. Residual stress measurements are performed on welded joints to validate the simulation results. The validated residual stress distributions can be used for the life time assessment and failure mode predictions of the welded joints.; JRC.F.4-Innovative Technologies for Nuclear Reactor Safety

‣ Rethinking Sentiment Analysis in the News: from Theory to Practice and back

Português
Most sentiment analysis work has been carried out on highly subjective text types where the target is clearly defined and unique across the text (movie or product reviews). However, when applying sentiment analysis to the news domain, it is necessary to clearly define the scope of the task, in a more specific manner than it has been done in the field so far. The main tasks we identified for news opinion mining are: definition of the target; separation of the good and bad news content from the good and bad sentiment expressed on the target; and analysis of clearly marked opinion that is expressed explicitly, not needing interpretation or the use of world knowledge. It is furthermore important to distinguish three different possible views on newspaper articles ¿ author, reader and text. These have to be addressed differently at the time of analysing sentiment, especially the case of author intention and reader interpretation, where specific profiles must be defined if the proper sentiment is to be extracted.; JRC.G.2-Global security and crisis management

40 agnelli di razza Sarda a un’età compresa tra 1 e 7 giorni e peso vivo compreso tra 2,50 e 6,15 Kg., sono stati suddivisi in due gruppi sperimentali di 20 soggetti ciascuno: il gruppo T è stato identificato elettronicamente mediante un transponder intraperitoneale; l’altro (gruppo C) è stato tenuto come controllo. Gli agnelli di entrambi i gruppi sono stati controllati clinicamente, pesati settimanalmente e infine macellati a età compresa tra 28 e 35 giorni. Nel gruppo T è stata verificata la leggibilità del transponder sugli animali in vivo e post mortem nella catena di macellazione. L’ incremento ponderale medio giornaliero (268,7 gr vs 251,1 gr), resa in carcassa “alla romana” (64,12% vs 63,78%), e resa in carcassa (52,74% vs 53,08%) non hanno mostrato differenze statisticamente significative fra i gruppi T e C. La leggibilità e il recupero dei transponders sono risultati del 100%.; JRC.G.7-Traceability and vulnerability assessment

Food security monitoring requires effective crop status assessment and yield forecasting methodologies and tools. Such tools need to build on a thorough knowledge of the crop production systems of the region under monitoring. The Food and Agriculture Organization of the United Nations (FAO) published in 1995 a database of the Crop production system zones (CPSZ) of the seven member states of the Intergovernmental Authority on Development (IGAD). This paper presents the main characteristics of a new version under development: database improvements and the methodology to define the new crop production system zones.; JRC.DG.G.3-Monitoring agricultural resources

Português
The increasing use of experimental platforms for networking research is due to their ability to support experimentation with complex systems, like the Internet, that simplistic simulators and small scale testbeds fail to reproduce. Therefore many projects and research initiatives have spawned - mainly in the field of Future Internet architectures. Although numerous publications can be found, most of them refer to prototypes and work in progress rather than to publicly available software that is ready to be widely used for the creation of testbeds. The first contribution is the development of a framework for comparing the available software based on their features. The second contribution is a literature review of state-of-the-art tools and their comparison under common criteria. This systematic analysis allows other researchers to make informed decisions about the usability of already available tools and decrease the initial cost of developing a new testbed, leading to an even wider use of such platforms. Our work provides the reader with a useful reference list of readily available software to choose from while designing or upgrading a research infrastructure, laboratory or experimentation facility.; JRC.G.6-Security technology assessment

The study focuses on the analysis of accidental events that resulted in the unwanted formation and release of hazardous substances not present on the site in normal conditions. The typical accident scenario involving unwanted and unforeseen reactions were identified. Data on the chemical system involved in the accidents and on the substances formed were collected and organized in a specifically developed database. The information collected evidences the relevance of the hazards due to the formation and release of hazardous substances as a consequence of "out of control" conditions in industrial facilities. In the perspective of the application of "Selevo II" directive, the complex links existing between the chemical system present in normal conditions and the substances that may be formed in accidental events require the development of a systematic approach to the problem.; JRC.(ISIS)-Institute For Systems, Informatics And Safety
