test_1136,"Intuitively, the less the direction of accumulated gradients is moved by the gradients of a new minibatch, the more certainty there is about the gradient direction.","we propose that the magnitude of the angle fluctuation relates to the certainty of the model parameter optimization direction, and may therefore serve as a measure of optimization difficulty.",reasoning
test_1137,"But after the direction of gradients has stabilized, accumulating more mini-batches seems useless as the gradient direction starts to fluctuate.","we suggest to compute dynamic and efficient batch sizes by accumulating gradients of mini-batches, while evaluating the gradient direction change with each new mini-batch, and stop accumulating more mini-batches and perform an optimization step when the gradient direction fluctuates.",reasoning

test_1146,"Initially, we tried to fine-tune BERT (Devlin et al., 2019), but this did not work well, probably because we did not have enough data to perform the fine-tuning.","eventually we opted to use BERT (and variations thereof) as a sentence encoder, and to perform max-pooling on the penultimate layer to obtain a representation for an input piece of text.",reasoning

test_1497,"This ability, obviously, is not what we desire because 1) in real world applications, most entity mentions are new and unseen, which means out-of-dictionary mentions will dominate the test process; 2) because the training instances are very limited in open situations, it is too expensive to achieve high mention coverage; 3) many longtail mentions in the training set would be oneshot, i.e., the mention only appears once in the training data.",it is necessary to exploit whether NER models can still reach reasonable performance in low mention coverage situation.,reasoning
test_1498,"We believe this is because, as some previous studies in other tasks (Zhang et al., 2016;Lu et al., 2019) have pointed out, neural networks have strong ability and tendency to memorize training instances.","the high mention coverage will mislead the models to mainly memorize and disambiguate frequent entity names even though they are irregular, but ignore informative context patterns which are useful for generalization over unseen mentions.",reasoning

test_2358,The overarching objective of our work is to access the large body of domain-specific information available in Frequently Asked Question sites (FAQ for short) via conversational Question Answering (QA) systems.,"we want to know whether current techniques are able to work with limited training data, and without needing to gather data for each target FAQ domain.",entailment
test_2359,"More specifically, if a user has an information need and asks a question to a conversational QA system on a FAQ, the system can search for similar questions which have already been answered, or the system can directly search in existing answer passages.","there are two ways to check automatically if the forum contains a relevant answer passage to a new question: (1) question retrieval, where relevant or similar questions are searched (and thus, the answer for this relevant question is taken as a relevant answer), and (2) answer retrieval, where relevant answers are searched directly among existing answers.",entailment
test_2360,"Conversational QA systems are more complex, as they need to deal with a sequence of possibly inter-dependent questions.",the meaning of the current question may depend on the dialogue history.,entailment

test_2363,"First, while state-of-the-art models for structure prediction in NLP used to rely heavily on intricate formal structures and carefully designed features (or feature-templates) (Zhang and Nivre, 2011; Zhang and Clark, 2011a), current neural models provide a form of representation learning and may be viewed as automatic feature-extractors (Kiperwasser and Goldberg, 2016; Dozat and Manning, 2018).","as long as the input object can be represented as a vector, the neural model will learn how to map it to the appropriate set of structural decisions, without having to write features or feature-templates by hand.",entailment
test_2364,"Subsequent SPMRL events and shared tasks (Seddah et al., 2013b; Tsarfaty, 2013; Seddah et al., 2014b) illustrated how methodologies and modeling assumptions for English NLP often break down in the face of such typologically diversity.","while most NLP models can in principle be trained on data in any given language, 1 such models are often developed with English in mind, and the bias injected into such models is not optimal for languages that exhibit flexible word order, and rich word-internal structure, as is the case in MRLs.",entailment
test_2365,It is an open question whether these word-pieces capture relevant aspects of morphology.,"it is unclear that the strategy of relying on chars or char-strings is adequate for encoding nonconcatenative phenomena that go beyond simple character sequencing, such as templatic morphology, substraction, reduplication, and more (Ackerman and Malouf, 2006; Blevins, 2016).",entailment
test_2366,"As a complementary area of investigation, a plausible direction would be to shift the focus from the decomposition of words into morphemes, to the organization of words as complete paradigms.","instead of relying on sub-word units, identify sets of words organized into morphological paradigms (Blevins, 2016).",entailment

test_2382,"In order to overcome these issues, we propose a novel deep learning model for RE that uses the dependency trees to extract the syntax-based importance scores for the words, serving as a tree representation to introduce syntactic information into the models with greater generalization.",we leverage Ordered-Neuron Long-Short Term Memory Networks (ON-LSTM) to infer the model-based importance scores for RE for every word in the sentences that are then regulated to be consistent with the syntax-based scores to enable syntactic information injection.,entailment
test_2383,"A notable insight in these recent studies is that the syntactic trees of the input sentences (i.e., the dependency trees) can provide effective information for the deep learning models, leading to the stateof-the-art performance for RE recently (Xu et al., 2015; Tran et al., 2019).","the previous deep learning models for RE has mostly exploited the syntactic trees to structure the network architectures according to the word connections presented in the trees (e.g., performing Graph Convolutional Neural Networks (GCN) over the dependency trees ).",entailment
test_2384,"Although the dependency connections might be less specific to the training data than the whole tree structures, the major limitation of the edge-based representation is that it only captures the pairwise (local) connections between the words and completely ignores the overall (global) importance of the words in the sentences for the RE problem.","some words in a given sentence might involve more useful information for relation prediction in RE than the other words, and the dependency tree for this sentence can help to better identify those important words and assign higher importance scores for them (e.g., choosing the words along the shortest dependency paths between the two entity mentions).",entailment
