Log-linear models and more recently neural network models used forsupervised relation extraction requires substantial amounts of training data andtime, limiting the portability to new relations and domains. To this end, we propose a training representation based on the dependency paths between entities in adependency tree which we call lexicalized dependency paths (LDPs). We showthat this representation is fast, efficient and transparent. We further propose representations utilizing entity types and its subtypes to refine our model and alleviatethe data sparsity problem. We apply lexicalized dependency paths to supervisedlearning using the ACE corpus and show that it can achieve similar performancelevel to other state-of-the-art methods and even surpass them on severalcategories. 展开更多

Lexicalized reordering models are very important components of phrasebased translation systems.By examining the reordering relationships between adjacent phrases,conventional methods learn these models from the word aligned bilingual corpus,while ignoring the effect of the number of adjacent bilingual phrases.In this paper,we propose a method to take the number of adjacent phrases into account for better estimation of reordering models.Instead of just checking whether there is one phrase adjacent to a given phrase,our method firstly uses a compact structure named reordering graph to represent all phrase segmentations of a parallel sentence,then the effect of the adjacent phrase number can be quantified in a forward-backward fashion,and finally incorporated into the estimation of reordering models.Experimental results on the NIST Chinese-English and WMT French-Spanish data sets show that our approach significantly outperforms the baseline method. 展开更多

Currently,in STEM environments,female employees are often recognized as minorities due to their positioning or occupancy rate,which may lead to experiences of“imposter syndrome”.This study applies frameworks of mixed-gender discourse,such as limited involvement in activity as an agent,markedness,and gender-differentiated roles,to clarify how women in STEM position themselves or are positioned by the society.Using corpus linguistics and content analysis,it is clarified that female researchers are usually linguistically marked or tend to distinguish themselves as non-experts.Thus,their portrayal within a misogynistic society may considerably interact with how female researchers represent themselves. 展开更多

Lexical analysis is a fundamental task in natural language processing,which involves several subtasks,such as word segmentation(WS),part-of-speech(POS)tagging,and named entity recognition(NER).Recent works have shown that taking advantage of relatedness between these subtasks can be beneficial.This paper proposes a unified neural framework to address these subtasks simultaneously.Apart from the sequence tagging paradigm,the proposed method tackles the multitask lexical analysis via two-stage sequence span classification.Firstly,the model detects the word and named entity boundaries by multilabel classification over character spans in a sentence.Then,the authors assign POS labels and entity labels for words and named entities by multi-class classification,respectively.Furthermore,a Gated Task Transformation(GTT)is proposed to encourage the model to share valuable features between tasks.The performance of the proposed model was evaluated on Chinese and Thai public datasets,demonstrating state-of-the-art results. 展开更多

[Objective] To examine the grammar model based on lexical substring exac- tion for RNA secondary structure prediction. [Method] By introducing cloud model into stochastic grammar model, a machine learning algorithm suitable for the lexicalized stochastic grammar model was proposed. The word grid mode was used to extract and divide RNA sequence to acquire lexical substring, and the cloud classifier was used to search the maximum probability of each lemma which was marked as a certain sec- ondary structure type. Then, the lemma information was introduced into the training stochastic grammar process as prior information, realizing the prediction on the sec- ondary structure of RNA, and the method was tested by experiment. [Result] The experimental results showed that the prediction accuracy and searching speed of stochastic grammar cloud model were significantly improved from the prediction with simple stochastic grammar. [Conclusion] This study laid the foundation for the wide application of stochastic grammar model for RNA secondary structure prediction. 展开更多

The paper discusses SL learners' lexical competence from O'Connor's Five Steps of Vocabulary Acquisition Theory, Collins & Loftus's Semantic Network Theory and Fay & Cutler's Mental Lexicon Theory. From the discussion, the author finds that second language learners' lexical competence includes the following aspects: the ability to recall the words which are similar to the target words in spelling and pronunciation; the ability to recall the synonyms of the target words; the ability to recall the antonyms of the target words; and the ability to recall the related words which come together with the target words in a context. Meanwhile it advances some strategies to develop the corresponding competence. 展开更多

It should be presupposed that all writers and texts have their individual qualities before the analysis goes ahead.In this paper,the analysis will be made respectively in terms of the four categories listed as follows:lexical categories,grammatical categories,figures of speech,and cohesion and context.We can draw a conclusion that the style of D.H.Lawrence is simpleness and directness and he seems not fond of complicating the superficial account,and turns to the natural and the essential tools to reveal the most original and animalized nature of the human being which,in his mind,is the most important and the essence of the nature rules. 展开更多

Traditionally,language is considered to be a grammar vocabulary dichotomy system,and grammar and vocabulary seem to be independent of each other.This deep-rooted notion is particularly prevalent in Chinese English teaching and learning.Michael Lewis,the author of the Lexical Approach challenged the standard view of dividing language teaching into grammar and vocabulary.He believes that language is grammaticalised lexis,not lexicalized grammar,and lexis is the core of language learning while grammar is subordinate to it.This paper intends to explore its theoretical foundations and emphasize the great significance of the Lexical Approach to college English teaching in China. 展开更多

With rapid development of China,a growing number of foreign products are entering the Chinese market.An excellent translation of a product’s advertisement from English to Chinese undoubtedly contributes to its successful promotion in the Chinese market.Although the translation practice contains multiple difficulties,the translation of lexical stylistic devices is a big challenge for translators.It is not simply because lexical stylistic devices are diverse and various in form,but also because most devices involve linguistic and cultural differences between English and Chinese.This thesis analyzed a number of current English to Chinese translations of the devices in commercial advertisements,which mainly come from two translation scholars’works and official websites of world-known brands.By analyzing the selected data,seven translation strategies are found to be the major translation strategies in this respect,namely literal translation,free translation,flexible translation,extended translation,adaptation translation,compensation translation and amplification translation strategies.Moreover,a number of linguistic and cultural issues which need to be considered by translators are also illustrated here. 展开更多
