Subjectivity in natural language refers to aspects of used express opinions, evaluations, and speculations. There are numerous processing applications for which subjectivity analysis is relevant, including information extraction text categorization. The goal this work learning subjective from corpora. Clues generated tested, low-frequency words, collocations, adjectives verbs identified using distributional similarity. features also examined working together concert. features, different data...
There is a need to identify key existing and emerging issues relevant digitalisation in agricultural production that would benefit from stronger evidence base help steer policy formulation. To address this, prioritisation exercise was undertaken priority research questions concerning digital agriculture the UK, but with view also informing international contexts. The uses an established effective participatory methodology for capturing ordering wide range of views. method involves...
Partners in Expert Working Group WG2 of the COST Action METHAGENE have used several methods for measuring methane output by individual dairy cattle under various environmental conditions. Methods included respiration chambers, sulphur hexafluoride (SF6) tracer technique, breath sampling during milking or feeding, GreenFeed system, and laser detector. The aim current study was to review compare suitability large-scale measurements animals, which may be combined with other databases genetic...
Fearful behavioral responses to handling (temperament) are undesirably associated with ADG and meat quality in infrequently handled Bos indicus cattle. It has never been assessed whether these relationships exist calmer taurus breeds systems where is more frequent. Such predominate some countries beef production a major agricultural activity. During fattening, 144 crossbred cattle from Limousin Aberdeen Angus sires were for temperament using 4 approaches: response movement along race (race...
The aim of this study was to assess combining location, acceleration and machine learning technologies detect estrus in dairy cows. Data were obtained from 12 cows, which monitored continuously for days. A neck mounted device collected 25,684 records location acceleration. Four machine-learning approaches tested (K-nearest neighbor (KNN), back-propagation neural network (BPNN), linear discriminant analysis (LDA), classification regression tree (CART)) automatically identify cows indicators...
Risk factors associated with voluntary and involuntary culling within a Holstein-Friesian dairy cow research herd were identified. Data studied from 3498 completed lactations the Langhill between January 1990 June 2008. During this period cows based on two different farms in Scotland. The rate of milking was approximately 25 per cent annum. Approximately 68 culled classified as involuntary. association risk incidence investigated using general linear mixed model. Of 838 culled, 59 before...
Methane (CH4) emissions by dairy cows vary with feed intake and diet composition. Even when fed on the same at intake, however, variation between in CH4 can be substantial. The extent of among commercial farms is unknown, but developments methodology now permit quantification individual under conditions. aim this research was to assess eructed during milking farms. Enteric from 1964 across 21 were measured for least 7 days/cow using analysers robotic stations. Cows predominantly Holstein...
Enteric methane (CH 4 ) is a by-product from fermentation of feed consumed by ruminants, which represents nutritional loss and also considered contributor to climate change. The aim this research was use individual animal data 17 published experiments that included sheep ( n = 288), beef cattle 71) dairy cows 284) develop an empirical model describe enteric CH emissions both sheep, then evaluate the alongside equations literature. Data were obtained studies in United Kingdom (UK) Australia,...
The aim of this study was to investigate using existing image recognition techniques predict the behavior dairy cows. A total 46 individual cows were monitored continuously under 24 h video surveillance prior calving. annotated for behaviors standing, lying, walking, shuffling, eating, drinking and contractions each cow from 10 19,191 records obtained a non-local neural network trained validated on clips behavior. This showed that used correctly classified seven 80% or more time in dataset....
Enteric methane production from livestock is an important source of anthropogenic greenhouse gas emissions. The aim the present study was to (1) assess effect long-term breeding for kilograms milk fat plus protein and (2) investigate influence parity, genetic line diet on predicted enteric emissions Holstein Friesian dairy cows. Analyses were based 17 years experimental data lactating dry cows, housed at pasture. Restricted maximum likelihood (REML) used effects output A non-linear equation...
Grazed pastures in south-eastern Australia are typically based on temperate (C3) species, such as perennial ryegrass (Lolium perenne). With predictions of warming to occur this region, there has been growing interest the performance more heat-tolerant and deep-rooted subtropical (C4) pasture grasses, kikuyu (Pennisetum clandestinum). This study used an existing model estimate production compared with commonly at seven sites Australia, using historical baseline climate scenario between 1971...
This paper presents a corpus study of evaluative and speculative language. Knowledge such language would be useful in many applications, as text categorization summarization. Analyses annotator agreement characteristics subjective are performed. yields knowledge needed to design effective machine learning systems for identifying
