Bilingual lexicon induction focuses on learning word translation pairs,also known as bitexts,from monolingual corpora by establishing a mapping between the source and target embedding spaces.Despite recent advancements,bilingual lexicon induction is limited to inducing bitexts consisting of individual words,lacking the ability to handle semantics-rich phrases.To bridge this gap and support downstream cross-lingual tasks,it is practical to develop a method for bilingual phrase induction that extracts bilingual phrase pairs from monolingual corpora without relying on cross-lingual knowledge.In this paper,the authors propose a novel phrase embedding training method based on the skip-gram structure.Specifically,a local hard negative sampling strategy that utilises negative samples of central tokens in sliding windows to enhance phrase embedding learning is introduced.The proposed method achieves competitive or superior performance compared to baseline approaches,with exceptional results recorded for distant languages.Additionally,we develop a phrase representation learning method that leverages multilingual pre-trained language models.These mPLMs-based representations can be combined with the above-mentioned static phrase embeddings to further improve the accuracy of the bilingual phrase induction task.We manually construct a dataset of bilingual phrase pairs and integrate it with MUSE to facilitate the bilingual phrase induction task. 展开更多

The method extracts phrase pairs that are not strictly consistent with word align- ments. Two types of constraints on word positions are investigated for this method. Furthermore, n-best alignments are introduced for phrase extraction instead of the one-best. Experimental results show that the proposed approach outperforms the baseline system, Pharaoh system, for both one-best and n-best alignments. 展开更多

Translators frequently come across metaphors and similes, which are important ways of figure of speech. Figures of speech are actually vehicles of culture, and metaphorical phrases are the essence of human's culture. So the strategies adopted in the translation of metaphors and similes are the reflection of the translators' attitude towards culture. This paper holds the belief that foreignization should be the main translation strategy when dealing with the metaphorical phrases bearing cultural connotations. 展开更多

There are three probabilities to claim that Mandarin Chinese has multiple Determiner Phrase (DP) structures: (1) Simpson (2001) takes “de” in nominal phrase as the head of the structure: “Zhangsan de shu” is a DP and “de” is the head D. In this theory, when “de” and demonstratives like “this/that” appear in the same structure, there is going to be a multiple DP structure. (2) Huang, Li & Li (2008) take both pronouns and demonstratives as the heads of the appositive structures like “tamen zhe sange haizi”. In this opinion, Mandarin Chinese has Split-D structures like Italian, Hungarian and Greek. (3) It seems that a Mandarin DP could have double heads D when two determiners both appear in the same structure. In “renhe zhe lei wenti”, the determiners “renhe” and “zhe” both appear. The structure is going to be analyzed as a multiple DP or a Split-D structure. However, the paper proves that Mandarin Chinese has no multiple DP structures, not like Italian, Hungarian or Greek. 展开更多

A surge in post-publication activity related to editing,including by technical editors and copyeditors,is worthy of some discussion.One of these issues involves the issue of'tortured phrases',which are bizarre terms and phrases in academic papers that replace standard English expressions or jargon.This phenomenon may reveal an attempt to avoid the detection of textual similarity or to masquerade plagiarism,and yet remain undetected by editors,peer reviewers and text editors.Potentially thousands of cases have already been discovered and reported publicly on the post-publication platform PubPeer.In this opinion paper,35 cases from ranked scholarly journals are presented,mainly the fields of materials,computer and engineering sciences.This collation serves to expand discussion about this integrity-related phenomenon and to increase educational awareness of the topic. 展开更多

In Mandarin Chinese,when the noun head appears in the context,a quantity noun phrase can be reduced to a quantity phrase with the noun head omitted.This phrase structure is called elliptical quantity noun phrase.The automatic recovery of elliptical quantity noun phrase is crucial in syntactic parsing,semantic representation and other downstream tasks.In this paper,we propose a hybrid neural network model to identify the semantic category for elliptical quantity noun phrases and realize the recovery of omitted semantics by supplementing concept categories.Firstly,we use BERT to generate character-level vectors.Secondly,Bi-LSTM is applied to capture the context information of each character and compress the input into the context memory history.Then CNN is utilized to capture the local semantics of n-grams with various granularities.Based on the Chinese Abstract Meaning Representation(CAMR)corpus and Xinhua News Agency corpus,we construct a hand-labeled elliptical quantity noun phrase dataset and carry out the semantic recovery of elliptical quantity noun phrase on this dataset.The experimental results show that our hybrid neural network model can effectively improve the performance of the semantic complement for the elliptical quantity noun phrases. 展开更多

It is widely known that a finite verb phrase(fVP)of a clause in English consists of three components:tense,aspect and voice.While the two tenses,present and past,and the two voices,active and passive,are recognized and generally agreed,the number and constituents of aspects may not be so simple and they are open to dispute.This paper proposes that a new aspect,the“modal”aspect,be included in addition to the commonly recognized ones,namely“simple”,“perfect”and“continuous”(also known as“progressive”).With the inclusion of the“modal”aspect,there are four single aspects:“simple”,“modal”,“perfect”and“continuous”.They can be combined to form multiple aspects according to the aforesaid sequence.The“modal”aspect is realized with a modal verb(any ofthe modal verbs will/would,shall/should,can/could,may/might,must,ought to,used to and the two semi-modals,“need”and“dare”in interrogative and negative structures).Whenever a modal verb is used,the verb phrase is in the modal aspect.The modal verb to be used is for the interlocutor to decide and falls beyond this discussion,which focuses on the structure of the fVP of the English language.The two tenses,eight aspects and two voices(active and passive)make up the 32 TAVs(an acronym formed with“Tense”,“Aspect”and“Voice”)of the English fVP.The“discovery”of the“modal”aspect and its incorporation in the aspect system of English might have a significant impact on the learning of English for non-native speakers as they would have a clearer and more precise concept about the“TAVs”of the English fVP. 展开更多

In this work,an approach is proposed to acquire synonymous attribute phrases of named entities(NEs) from an online encyclopedia.Synonymous attribute phrases are the phrases that express the same attribute with different surface forms for a class of NEs.Specifically,the proposed approach is composed of three stages.Firstly,the entries related to a given NE class are automatically selected from an online encyclopedia.Secondly,attribute phrases are extracted based on the statistics of phrase frequency.Thirdly,synonymous attributes are identified in a pairwise manner through a classification framework combining multiple features.The proposed approach is applied on Baidu Baike,a Chinese online encyclopedia,for four different NE classes.Experimental results show that the approach obtains an average precision of 74%and an average F-value of 65%for the four NE classes.In particular,thousands of synonymous attribute phrase pairs are acquired for each class,which demonstrates the effectiveness of the proposed approach. 展开更多
