We present a proposal for the annotation of multi-word expressions in a 1M corpus of contemporary portuguese. Our aim is to create a resource that allows us to study multi-word expressions (MWEs) in their context. The corpus will be a valuable additional resource next to the already existing MWE lexicon that was based on a much larger corpus of 50M words. In this paper we discuss the problemati...

This study aims to assess the usefulness of multi-word expressions (MWEs) as features for a readability formula that predicts the difficulty of texts for French as a foreign language. Using a MWE extractor combining a statistical approach with a linguistic filter, we define 11 predictors. These take into account the density and the probability of MWEs, but also their internal structure. Our exp...

Response to Referee 1 General comments The drought treatment in 2008 delayed the recovery of the redox potential during the first year of flooding in 2009. For example, methane production in the flooded plots reached the level of the control plots not before July/August 2009 (Estop-Aragones et al., unpublished data). In the growing season of 2010, no delay in methane production was observed bet...

This paper describes the research project on the development of an ontology-based semantic search system for drought management of the Chi River Basin (CRB), Thailand. The research methods included Ontology Development 101 by adopting Noy & McGuinness (2001) and Ontology-based Application Management framework by adopting Buranarach et al. (2012). Seventeen experts including ten experts in the a...

Soil water stress has paramount effects on water uptake by roots and its use by shoots. In this study, we determined changes in root hydraulic conductivity (Lpr) and morphology under drought stress and how they regulate shoot gas exchange and water use efficiency in alfalfa and sorghum, two crops with contrasting adaptations to drought, the former exhibiting strong drought avoidance and the lat...

introduction: drought is a creeping natural phenomenon, which can occur in any region. such phenomenon not only affects the region subjected to drought, but its adverse effects can also be extended to other adjacent regions. this phenomenon mainly starts with water deficiency (say less than long- term mean of variable under study such as rainfall, streamflow, groundwater level or soil moisture)...

A practical approach was developed in the study for drought monitoring in Guangdong province of China on the basis of vegetation supply water index (VSWI) and precipitation distance index (PDI). A comprehensive index for assessment of agro-drought severity (SADI) was then established from the normalized VSWI and PDI. Using MODIS satellite images and precipitation data from ground-observed meteo...

Drought is one of the most severe stresses, endangering crop yields worldwide. In order to select drought tolerant genotypes, access to exotic germplasm and efficient phenotyping protocols are needed. In this study the high-throughput phenotyping platform "The Plant Accelerator", Adelaide, Australia, was used to screen a set of 47 juvenile (six week old) wild barley introgression lines (S42ILs)...

Identification of Multi-Word Expressions (MWEs) lies at the heart of many natural language processing applications. In this research, we deal with a particular type of Hebrew MWEs, VerbNoun MWEs (VN-MWEs), which combine a verb and a noun with or without other words. Most prior work on MWEs classification focused on linguistic and statistical information. In this paper, we claim that it is essen...
