soil salinity affects ions concentrationss of plant tissues and this may alter the merits quality of medicinal plants. experiments were conducted during 2003 at the the isfahan university of technology campus, isfahan, iran, to assess the effects of five soil salinity levels (3.2, 3.6, 4.5, 5.4 and 7.5 ds m-1) on na, k, and ca contents of borage and echium. each plant species was studied in a s...

This report documents our efforts to develop a Generation Challenges 2011 surface realization system by converting the shared task deep inputs to ones compatible with OpenCCG. Although difficulties in conversion led us to employ machine learning for relation mapping and to introduce several robustness measures into OpenCCG’s grammar-based chart realizer, the percentage of grammatically complete...

Grammar-based surface realizers require inputs compatible with their reversible, constraint-based grammars, including a proper representation of unbounded dependencies and coordination. In this paper, we report on progress towards creating realizer inputs along the lines of those used in the first surface realization shared task that satisfy this requirement. To do so, we augment the Universal ...
