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

Named entity recognition(NER)is an important part in knowledge extraction and one of the main tasks in constructing knowledge graphs.In today’s Chinese named entity recognition(CNER)task,the BERT-BiLSTM-CRF model is widely used and often yields notable results.However,recognizing each entity with high accuracy remains challenging.Many entities do not appear as single words but as part of complex phrases,making it difficult to achieve accurate recognition using word embedding information alone because the intricate lexical structure often impacts the performance.To address this issue,we propose an improved Bidirectional Encoder Representations from Transformers(BERT)character word conditional random field(CRF)(BCWC)model.It incorporates a pre-trained word embedding model using the skip-gram with negative sampling(SGNS)method,alongside traditional BERT embeddings.By comparing datasets with different word segmentation tools,we obtain enhanced word embedding features for segmented data.These features are then processed using the multi-scale convolution and iterated dilated convolutional neural networks(IDCNNs)with varying expansion rates to capture features at multiple scales and extract diverse contextual information.Additionally,a multi-attention mechanism is employed to fuse word and character embeddings.Finally,CRFs are applied to learn sequence constraints and optimize entity label annotations.A series of experiments are conducted on three public datasets,demonstrating that the proposed method outperforms the recent advanced baselines.BCWC is capable to address the challenge of recognizing complex entities by combining character-level and word-level embedding information,thereby improving the accuracy of CNER.Such a model is potential to the applications of more precise knowledge extraction such as knowledge graph construction and information retrieval,particularly in domain-specific natural language processing tasks that require high entity recognition precision. 展开更多

Vocabulary researches play an important role in language teaching.In recent decades,lexical complexity has drawn great attention by researchers and scholars.A large number of empirical studies have been conducted to find out whether correlations exist between writing quality and lexical complexity in written texts.In the present study,299 English learners participated in the experiment from a comprehensive university.The data were timed CE texts translated by these learners.This study intends to answer the two questions with the assistance of such tools as LCA and SPSS.After analyzing the data with 9 indices from LCA,the results of this study are as follows:1.Chinese students’translated texts gain a high lexical density,which shows that content words can account for a large percentage in narrative translations.In the lexical sophistication measures,LS1 and LS2 do not differ greatly while CVS1 gets the greatest fluctuation.Among lexical variation indices,NDW is generally high.2.All indices in lexical variation and lexical sophistication show a high positive correlation with translation quality,while lexical density bears a negative relationship with translation quality.The findings of the current study indicate students’vocabulary use in translation and provide implications for English teaching,especially translation and vocabulary teaching. 展开更多

This paper serves as a comprehensive guide to the recent work on lexical knowledge in China from the year of 2000 to 2009. It covers the two conventional dimensions of vocabulary knowledge: The breadth and depth. The recent wok on the breadth of vocabulary knowledge extends beyond the old fashion of rigid word counting of learners at various proficiency levels. Meanwhile, multi-dimensional study is also witnessed when it comes to the research into the depth of lexical knoweldge, the developmental and dimensional perspective, along with psycholinguistic account of the incremental nature of the acquisition process. 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

As teachers of EFL (English as a Foreign Language) in the Kingdom of Saudi Arabia, we are sometimes flabbergasted by the errors that the/earners make in their English scripts. Apparently, there was no pattern to these errors. However, when the researcher observed the frequency of similar error over a few years of her experience as an EFL faculty for Saudi learners, the theory of Lexical Relations appeared to offer an answer. Therein also lies the genesis of the current study. In a positive development, the study did bring to light certain factors that directly played a role in the Saudi EFL learners' English errors. These have been presented in this paper with the hope that with the diagnosis in hand, it will be easier for the EFL teachers to find a solution to the dearth of English proficiency among the Saudi EFL learners. 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
