Report of CE on Semantic DS

This document reports on the core experiment on the Semantic DS [5]. The Semantic DS allows describing the world depicted by the AV content and interpreting that world, i.e., the “about” of the AV content or depicted narrative reality, which sometimes is imaginary. The CE originally started at the Maui meeting in December 1999 [4]. Progress reports of the CE were provided at the Geneva meeting [1], at the Beijing meeting [3], and at the La Baule meeting [2]. In La Baule, some components of the Semantic DS were promoted to the WD - Semantic DS, SemanticBase DS, Object DS, Event DS, AgentObject DS, SemanticPlace DS, SemanticTime DS, MediaOccurrence DS, and semantic relations-, and others were promoted to the XM – SemanticState DS, Concept DS, and AbstractionLevel datatype. The goal of this CE is to continue the refinement and evaluation of the Semantic DS and to continue the evaluation of the use of membership functions to describe relation strength. The AbstractionLevel datatype was promoted to CD before Pisa. At Pisa, the work to update the specification of the the SemanticTime, SemanticPlace, and Event DSs and to explain the methods for abstraction and the use of abstract concepts was started. The main tasks of this core experiment have been the following: 1. To refine the specification of the Semantic DS by solving open issues identified by reviewers and previous CEs; 2. To recommend the standardization of more semantic relations; 3. To continue the investigation of the use of membership functions to describe the strength of relations; 4. To generate simple and complex semantic descriptions of multimedia material, 5. To continue the implementation of a retrieval and browsing application/s that use/s the generated descriptions and that show/s the functionality of the DSs in the MDS XM, and 6. To recommend changes and additions to the Semantic DS based on the results of the experiment. The retrieval application that the CE continued the development of the software that had already been integrated into the XM for the Semantic DS

Semantics of Multimedia in MPEG-7

In this paper, we present the tools standardized by MPEG-7 for describing the semantics of multimedia. In particular, we focus on the abstraction model, entities, attributes and relations of MPEG-7 semantic descriptions. MPEG-7 tools can describe the semantics of specific instances of multimedia such as one image or one video segment but can also generalize these descriptions either to multiple instances of multimedia or to a set of semantic descriptions. The key components of MPEG-7 semantic descriptions are semantic entities such as objects and events, attributes of these entities such as labels and properties, and, finally, relations of these entities such as an object being the patient of an event. The descriptive power and usability of these tools has been demonstrated in numerous experiments and applications, these make them key candidates to enable intelligent applications that deal with multimedia at human levels

The nature of the Class I population in Ophiuchus as revealed through gas and dust mapping

The Ophiuchus clouds, in particular L~1688, are an excellent region to study the embedded phases of star formation, due to the relatively large number of protostars. However, the standard method of finding and characterizing embedded young stellar objects (YSOs) through just their infrared spectral slope does not yield a reliable sample. This may affect the age determinations, often derived from the statistics on the total number of embedded YSOs and pre-main sequence stars within a cloud.Our aim is to characterize the structure of protostellar envelopes on an individual basis and to correctly identify the embedded YSO population of L1688. Spectral maps of the HCO+ J=4--3 and C18O J=3--2 lines using the HARP-B array on the James Clerk Maxwell Telescope and SCUBA 850 micron dust maps are obtained of all sources in the L1688 region with infrared spectral slopes consistent with, or close to, that of embedded YSOs. Selected 350 micron maps obtained with the Caltech Submillimeter Observatory are presented as well. The properties, extent and variation of dense gas, column density and dust on scalesup to 1' are probed at 15" resolution. Using the spatial variation of the gas and dust, together with the intensity of the HCO+ J=4--3 line, we are able to accurately identify the truly embedded YSOs and determine their properties. RESULTS The protostellar envelopes range from 0.05 to 0.5 Msun in mass. The concentration of HCO+ emission (~0.5 to 0.9) is generally higher than that of the dust concentration. Combined with absolute intensities, HCO+ proves to be a better tracer of protostellar envelopes than dust, which can contain disk and cloud contributions. Our total sample of 45 sources, including all previously classified Class I sources, several flat-spectrum sources and some known disks, was re-classified using the ....Comment: accepted for publication in A&A, 29 pages including online appendi

Measurements of fiducial and differential cross sections for Higgs boson production in the diphoton decay channel at s√=8 TeV with ATLAS

Measurements of fiducial and differential cross sections are presented for Higgs boson production in proton-proton collisions at a centre-of-mass energy of s√=8 TeV. The analysis is performed in the H → γγ decay channel using 20.3 fb−1 of data recorded by the ATLAS experiment at the CERN Large Hadron Collider. The signal is extracted using a fit to the diphoton invariant mass spectrum assuming that the width of the resonance is much smaller than the experimental resolution. The signal yields are corrected for the effects of detector inefficiency and resolution. The pp → H → γγ fiducial cross section is measured to be 43.2 ±9.4(stat.) − 2.9 + 3.2 (syst.) ±1.2(lumi)fb for a Higgs boson of mass 125.4GeV decaying to two isolated photons that have transverse momentum greater than 35% and 25% of the diphoton invariant mass and each with absolute pseudorapidity less than 2.37. Four additional fiducial cross sections and two cross-section limits are presented in phase space regions that test the theoretical modelling of different Higgs boson production mechanisms, or are sensitive to physics beyond the Standard Model. Differential cross sections are also presented, as a function of variables related to the diphoton kinematics and the jet activity produced in the Higgs boson events. The observed spectra are statistically limited but broadly in line with the theoretical expectations
