Almost all automatic semantic role labeling (SRL) systems rely on a preliminary parsing step that derives a syntactic structure from the sentence being analyzed. This makes the choice of syntactic representation an essential design decision. In this paper, we study the influence of syntactic representation on the performance of SRL systems. Specifically, we compare constituent-based and dependency
Popular Abstract in Swedish Olika livsmiljöer och livsstilar kan ställa mycket olika krav på ett sinnesorgans uppbyggnad och funktion. Man kan därför förvänta sig att tex. ögonen hos ett lejon skiljer sig väsentligt från musslors, maskars eller djuphavsfiskars ögon. Det har också visat sig att om man undersöker ett öga i detalj så är det oftast mycket väl anpassat till just de förutsättningar som Functional aspects of the large diversity of eye design in prosobranch molluscs was investigated using morphological and optical methods. Three species from different habitats were investigated. Littorina littorea from Scandinavian intertidal rock habitats, Strombus raninus and S. gigas from tropical sand-flats and Ampularia sp. from heavily vegetated habitats in tropical fresh-water. Littorina a
Popular Abstract in Swedish Amylos-lipid-komplex är ett fenomen som förekommer i vardagliga livsmedel som innehåller stärkelse, t ex bröd och pasta. Dess struktur på molekylnivå kan liknas vid en "fransk hot dog"; franskbrödet motsvarar stärkelsemolekylen "amylos", som bildar en spiral. I dess tunnel stoppas en fet korv, vilken motsvarar en molekyl som har en lång, fet "svans". Molekylerna sitter This thesis is about the formation of amylose-lipid complexes, and their properties. Two forms of superstructures can be identified. Complex form I has more randomly distributed helices, while the structure of form II is crystalline and therefore exhibits the typical V-pattern in X-ray diffraction analyses. Form II has higher heat stability, and is produced by heating at a temperature at least suf
The extensive analysis of Nb II by Ryabtsev et al. (2000) has made it possible for us to measure branching fractions (BFs) in Nb II. The BFs have been measured from spectral line intensities, recorded with the Lund UV Fourier transform spectrometer in the wavelength region 2500 to 5000
A computational algorithm for the full information H∞ control problem for multi-delayed LTI systems is derived. The algorithm is based on a general operator approach in the spectral domain developed for finite-dimensional LTI plants. The simplicity of spectral operations and explicit formulas for computation make it possible to generalize it to infinite-dimensional plants. In the paper, a complete

Popular Abstract in Swedish Kostfiber visar på gynnsamma effekter på blodsockersvar, inflammationsmarkörer och blodfetter utifrån tre humanstudier som genomfördes i detta arbete. I en av studierna analyserades blod och urin med metabolomik. Det är en metod där man analyserar alla små molekyler (metaboliter) som finns i provet med hjälp av vätskekromatografi kopplat till masspektrometri. Med hjälp It is well-known that dietary fibre can have a positive effect on the development of lifestyle-dependent diseases such as cardiovascular disease and type 2 diabetes. However, the effect may be different for different kinds of fibre and different sub-populations at risk. Therefore, the effects of three different kinds of fibre on postprandial and long-term response in healthy subjects were investig
