Universal Mobile Information Retrieval

International audienceThe shift in human computer interaction from desktop computing to mobile interaction highly influences the needs for new designed interfaces. In this paper, we address the issue of searching for information on mobile devices, an area also known as Mobile Information Retrieval. In particular, we propose to summarize as much as possible the information retrieved by any search engine to allow universal access to information

JRC Ispra EMEP-GAW Regional Station for Atmospheric Research - 2007 Report

The aim of the JRC-Ispra station for atmospheric research (45°49'N, 8°38'E) is to monitor atmospheric parameters (pollutant concentrations and fluxes, atmospheric particle chemical composition, number size distribution and optical properties) to contribute in assessing the impact of European policies on air pollution and climate change. The station has been operated continuously since November 1985, with a gap in gas phase data due to a severe breakdown of the data acquisition system in 2003 though. The measurements performed in 2007 led to annual averages of ca. 32 µg m-3 O3, 0.8 µg m-3 SO2, 21 µg m-3 NO2 and 30 µg m-3 PM10. Carbonaceous species (organic matter plus elemental carbon) are the main constituents of PM2.5 (> 55 %) followed by NH4NO3 (20-30 %) and (NH4)2SO4 (10-20 %). The measurements confirmed the seasonal variations observed over the previous years, mainly driven by meteorology rather than by changes in emissions. Aerosol physical and optical properties were also measured in 2007. The average particle number (from 10 nm to 10 µm) was about 9200 cm-3 in 2007. The mean (close to dry) aerosol single scattering albedo (0.79) was low compared to the values generally observed in Europe, which means that the cooling effect of aerosols is reduced in our region compared to others. Long-term trends (over 20 years) show consistent decreases in sulfur concentrations and deposition, PM mass concentration (-0.9 µg m-3 yr-1) and in extreme ozone value occurrence frequency. The decreasing trends in oxidised and reduced nitrogen species are much less pronounced. However, historical minimum in NO3-, NH4+, (and SO42-) wet deposition, as well as in O3 pollution indicators (AOT40 and SOMO35) were observed in 2007.JRC.H.2-Climate chang

JRC Ispra EMEP - GAW Regional Station for Atmospheric Research - 2006 Report

The aim of the JRC-Ispra station for atmospheric research (45°49'N, 8°38'E) is to monitor atmospheric parameters (pollutant concentrations and fluxes, atmospheric particle chemical composition, number size distribution and optical properties) to contribute in assessing the impact of European policies on air pollution and climate change. The station has been operated continuously since November 1985, with a gap in gas phase data due to a severe breakdown of the data acquisition system in 2003 though. The measurements performed in 2006 led to annual averages of ca. 41 µg m-3 O3, 1.1 µg m-3 SO2, 21 µg m-3 NO2 and 33 µg m-3 PM10. Carbonaceous species (organic matter plus elemental carbon) are the main constituents of PM2.5 (> 50 %) followed by (NH4)2SO4 (10-20 %) and NH4NO3 (20-30 %). The measurements confirmed the seasonal variations observed over the previous years, mainly driven by meteorology rather than by changes in emissions. Aerosol physical and optical properties were also measured in 2006. The average particle number (from 6 nm to 10 µm) was about 10000 cm-3 in 2006. The mean (close to dry) aerosol single scattering albedo (a key parameter for determining the aerosol direct radiative forcing) was 0.79. Long-term trends (over 20 years) show decreases in sulfur concentrations and deposition, and in extreme ozone value occurrence frequency, although the latter was higher in compared to the last two years The decreasing trends in nitrogen oxides, reduced nitrogen species, and PM concentrations are much less pronounced.JRC.H.2-Climate chang

JRC Ispra EMEP - GAW Regional Station for Atmospheric Research 2008 Report

The aim of the JRC-Ispra station for atmospheric research (45°49'N, 8°38'E) is to monitor atmospheric parameters (pollutant concentrations and fluxes, atmospheric particle chemical composition, number size distribution and optical properties) to contribute in assessing the impact of European policies on air pollution and climate change. The station has been operated continuously since November 1985, with a gap in gas phase data due to a severe breakdown of the data acquisition system in 2003 though. The measurements performed in 2008 led to annual averages of ca. 34 µg m-3 O3, 0.7 µg m-3 SO2, 20 µg m-3 NO2 and 27 µg m-3 PM10. Carbonaceous species (organic matter plus elemental carbon) are the main constituents of PM2.5 (~57 %) followed by NH4NO3 (20-30 %) and (NH4)2SO4 (10-20 %). The data from 2008 confirmed the seasonal variations observed over the previous years, mainly driven by meteorology rather than by changes in emissions, as revealed by the lidar measurements. Aerosol physical and optical properties were also measured in 2008. The average particle number (from 10 nm to 10 µm) was about 8000 cm-3 in 2008. The mean (close to dry) aerosol single scattering albedo (0.75) was low compared to the values generally observed in Europe, which means that the cooling effect of aerosols is reduced in our region compared to others. Long-term trends (over 20 years) show consistent decreases in sulfur concentrations and deposition, PM mass concentration (-0.9 µg m-3 yr-1), and from 2003 in ozone concentrations too. The decreasing trends in oxidised and reduced nitrogen species are much less pronounced.JRC.H.2-Climate chang

JRC Ispra EMEP - GAW Regional Station for Atmospheric Research, 2009 Report

The aim of the JRC-Ispra station for atmospheric research (45°49¿N, 8°38¿E) is to monitor atmospheric parameters (pollutant concentrations and fluxes, atmospheric particle chemical composition, number size distribution and optical properties) to contribute in assessing the impact of European policies on air pollution and climate change. The station has been operated continuously since November 1985, with a gap in gas phase data in 2003 and 2009 due to a breakdown of the data acquisition system and lack of man-power, respectively. The measurements performed in 2009 led to annual average of 26.8 µg m-3 for PM10, well below the European annual limit value of 40 µg/m³ (the European directive 1999/30/EC for the year 2005 and onwards). In addition, the measurements performed in 2009 led to annual average of 19.0 µg m-3 for PM2.5, well below the future European annual limit value of 25 µg/m³ (European directive 2008/50/EC for the year 2015 and onwards). Carbonaceous species (organic matter plus elemental carbon) are the main constituents of PM2.5 (~57 %) followed by (NH4)2SO4 (24 %) and NH4NO3 (12 %). The data from 2009 confirmed the seasonal variations observed over the previous years, mainly driven by meteorology rather than by changes in emissions, as revealed by the lidar measurements. Aerosol physical and optical properties were also measured in 2009. The average particle number (from 10 nm to 10 µm) was about 7400 cm-3 and the mean geometric diameter was 70 nm. Their hygroscopic growth at 90% RH varies from <1.2 in December to 1.25 ¿ 1.35 (size dependent) in June. The mean (close to dry) aerosol single scattering albedo at ¿ = 550 nm was 0.76, and it was low compared to the values generally observed in Europe, which means that the cooling effect of aerosols is reduced in our region compared to others. Long-term trends (over 20 years) show consistent decreases in sulfur concentrations and deposition, PM mass concentration (about -0.9 µg m-3 yr-1), and from 2003 onwards also a slight decease in ozone concentrations too. The decreasing trends in oxidised and reduced nitrogen species are much less pronounced.JRC.DDG.H.2-Climate change and air qualit

The SUMMA Platform:A Scalable Infrastructure for Multi-lingual Multi-media Monitoring

The open-source SUMMA Platform is a highly scalable distributed architecture for monitoring a large number of media broadcasts in parallel, with a lag behind actual broadcast time of at most a few minutes. The Platform offers a fully automated media ingestion pipeline capable of recording live broadcasts, detection and transcription of spoken content, translation of all text (original or transcribed) into English, recognition and linking of Named Entities, topic detection, clustering and crosslingual multi-document summarization of related media items, and last but not least, extraction and storage of factual claims in these news items. Browser-based graphical user interfaces provide humans with aggregated information as well as structured access to individual news items stored in the Platform’s database. This paper describes the intended use cases and provides an overview over the system’s implementation
