A complete analysis of a geometric diagram hinges on interpreting both its fundamental primitives and the accompanying natural language text,yet existing models struggle to process the rich semantics within these descriptions,often leading to ambiguity and restricted reasoning.To address this,our work introduces a method that deeply integrates a Transformer-based text encoder within a sophisticated visual parsing architecture.Central to our approach is a novel Semantic-Guided Cross-Attention mechanism,which uses a global sentence representation as a semantic query to dynamically guide the model’s focus toward the most relevant visual primitives based on the textual context.This end-to-end process generates context-aware visual features that are then processed by a Graph Neural Network(GNN)to perform robust cross-modal reasoning.Validated on the large-scale PGDP5K and IMP-Geometry3K datasets,our method demonstrates substantial accuracy improvements in relationship parsing and geometric proposition generation,especially in challenging cases involving text-diagram ambiguity,and significantly surpasses current state-of-the-art baselines by offering a more effective framework for fusing deep textual semantics with visual information. 展开更多

Text-to-SQL旨在将自然语言问题翻译为可被数据库系统执行的SQL语句,从而为数据查询提供便利。随着大语言模型(LLMs)技术的发展,基于LLMs的Text-to-SQL提示方法成为该领域的主流解决方案。近年来,研究者在LLMs的提示词中加入线索(Hint)来传递具体的Text-to-SQL建议,以引导LLMs生成SQL。然而,现有线索多由研究者根据Text-to-SQL任务的特点人为撰写,其内容过于宽泛,难以根据具体的任务需求做出调整,无法适配所有Text-to-SQL任务。本文提出基于自动线索生成的Text-to-SQL提示方法Hint-SQL,它能够根据当前Text-to-SQL任务自动地生成合适的语义、操作和结构线索,从而引导LLMs生成语义一致、结构正确的SQL。为了生成任务定制化线索,我们构建了线索生成智能体(HAgent)。HAgent基于两阶段微调框架,由开源LLMs微调而来,该框架自动合成微调所需数据,无需人工标注,为监督微调和偏好学习优化提供支持。HintSQL既可以单独使用,也可以用来增强现有方法。大规模实验结果显示,HintSQL独立使用时可以媲美主流方法,也可以显著增强现有方法性能,在BIRD数据集上,HintSQL将当前最好方法的准确率提升到了71.58%,提升幅度达到4.37%。本研究揭示了线索在Text-to-SQL任务中的重要作用,为Text-to-SQL的后续研究提供了参考。 展开更多

Multimodal-based action recognition methods have achieved high success using pose and RGB modality.However,skeletons sequences lack appearance depiction and RGB images suffer irrelevant noise due to modality limitations.To address this,the authors introduce human parsing feature map as a novel modality,since it can selectively retain effective semantic features of the body parts while filtering out most irrelevant noise.The authors propose a new dual-branch framework called ensemble human parsing and pose network(EPP-Net),which is the first to leverage both skeletons and human parsing modalities for action recognition.The first human pose branch feeds robust skeletons in the graph convolutional network to model pose features,while the second human parsing branch also leverages depictive parsing feature maps to model parsing features via convolutional backbones.The two high-level features will be effectively combined through a late fusion strategy for better action recognition.Extensive experiments on NTU RGB t D and NTU RGB t D 120 benchmarks consistently verify the effectiveness of our proposed EPP-Net,which outperforms the existing action recognition methods.Our code is available at http://gffzz188fe103f8f1460asv6unpvf950656ucc.ffgz.tsg.suse.edu.cn/liujf69/EPP-Net-Action. 展开更多

In this paper, we present a full Chinese parsing system based on a two-stage approach. Rather than identifying all phrases by a uniform model, we utilize a divide and conquer strategy. We propose an effective and fast method based on Markov model to identify the base phrases. Then we make the first attempt to extend one of the best English parsing models i.e. the head-driven model to recognize Chinese complex phrases. Our two-stage approach is superior to the uniform approach in two aspects. First, it creates synergy between the Markov model and the head-driven model. Second, it reduces the complexity of full Chinese parsing and makes the parsing system space and time efficient. We evaluate our approach in PARSEVAL measures on the open test set, the parsing system performances at 87.53% precision, 87.95% recall. 展开更多

This paper proposes a new way to improve the performance of dependency parser: subdividing verbs according to their grammatical functions and integrating the information of verb subclasses into lexicalized parsing model. Firstly,the scheme of verb subdivision is described. Secondly,a maximum entropy model is presented to distinguish verb subclasses. Finally,a statistical parser is developed to evaluate the verb subdivision. Experimental results indicate that the use of verb subclasses has a good influence on parsing performance. 展开更多

Head-driven statistical models for natural language parsing are the most representative lexicalized syntactic parsing models, but they only utilize semantic dependency between words, and do not incorporate other semantic information such as semantic collocation and semantic category. Some improvements on this distinctive parser are presented. Firstly, "valency" is an essential semantic feature of words. Once the valency of word is determined, the collocation of the word is clear, and the sentence structure can be directly derived. Thus, a syntactic parsing model combining valence structure with semantic dependency is purposed on the base of head-driven statistical syntactic parsing models. Secondly, semantic role labeling(SRL) is very necessary for deep natural language processing. An integrated parsing approach is proposed to integrate semantic parsing into the syntactic parsing process. Experiments are conducted for the refined statistical parser. The results show that 87.12% precision and 85.04% recall are obtained, and F measure is improved by 5.68% compared with the head-driven parsing model introduced by Collins. 展开更多

A fast method for phrase structure grammar analysis is proposed based on conditional ran- dom fields (CRF). The method trains several CRF classifiers for recognizing the phrase nodes at dif- ferent levels, and uses the bottom-up to connect the recognized phrase nodes to construct the syn- tactic tree. On the basis of Beijing forest studio Chinese tagged corpus, two experiments are de- signed to select the training parameters and verify the validity of the method. The result shows that the method costs 78. 98 ms and 4. 63 ms to train and test a Chinese sentence of 17. 9 words. The method is a new way to parse the phrase structure grammar for Chinese, and has good generalization ability and fast speed. 展开更多

At present, there are two major limitations in existing methods for events recognition. One is that no algorithms are available to recognize events which happen alternately. The other is that the temporal relationship between atomic actions is not fully utilized. Aiming at these problems, an algo- rithm based on an extended stochastic context-free grammar (SCFG) representation is proposed for events recognition. Events are modeled by a series of atomic actions and represented by an extended SCFG. The extended SCFG can express the hierarchical structure of the events and the temporal re- lationship between the atomic actions. In comparison with previous work, the main contributions of this paper are as follows: ① Events (include alternating events) can be recognized by an improved stochastic parsing and shortest path finding algorithm. ② The algorithm can disambiguate the detec- tion results of atomic actions by event context. Experimental results show that the proposed algo- rithm can recognize events accurately and most atomic action detection errors can be corrected sim- ultaneously. 展开更多

Text-to-SQL语义解析任务旨在将自然语言问题转化为可执行的SQL语句。近年来,许多研究将预训练模型等方法应用到该任务中,并取得了一定的进展。然而,现有的预训练模型没有针对Text-to-SQL任务进行重新训练,不能很好地适应任务的场景语义特征信息,从而影响模型的解析性能。同时,许多方法还容易忽略自然语言问题与数据库模式间的关系,造成解析过程中语义模糊的问题。为解决这些问题,提出一种新的RGA-T5模型来完成Text-to-SQL语义解析任务。该模型在预训练模型T5中引入了关系感知异构图神经网络(HGNN),将输入的实体与关系构建为异构图上的节点,并通过应用图神经网络(GNN)实现模型对输入序列的语义关系感知。同时,还提出空间门控适配器,对其参数进行训练实现对预训练模型的微调,使模型能够针对该任务适应不同场景下的语义特征信息,减少无关信息的引入。实验结果表明,该模型在Spider数据集上相较于其他先进的Text-to-SQL解析方法取得了一定程度的性能提升,验证了所提方法的有效性。 展开更多

How to effectively manage and use Weibo comment information has become a research focus in the field of information content security. Three main tasks involved are emotion sentence identification and classification,emotion tendency classification,and emotion expression extraction. Combining with the latent Dirichlet allocation(LDA) model,a Gibbs sampling implementation for inference of our algorithm is presented,and can be used to categorize emotion tendency automatically with the computer. In accordance with the lower ratio of recall for emotion expression extraction in Weibo,use dependency parsing,divided into two categories with subject and object,summarized six kinds of dependency models from evaluating objects and emotion words,and proposed that a merge algorithm for evaluating objects can be accurately evaluated by participating in a public bakeoff and in the shared tasks among the best methods in the sub-task of emotion expression extraction,indicating the value of our method as not only innovative but practical. 展开更多

Due to the lack of long-range association and spatial location information,fine details and accurate boundaries of complex clothing images cannot always be obtained by using the existing deep learning-based methods.This paper presents a convolutional structure with multi-scale fusion to optimize the step of clothing feature extraction and a self-attention module to capture long-range association information.The structure enables the self-attention mechanism to directly participate in the process of information exchange through the down-scaling projection operation of the multi-scale framework.In addition,the improved self-attention module introduces the extraction of 2-dimensional relative position information to make up for its lack of ability to extract spatial position features from clothing images.The experimental results based on the colorful fashion parsing dataset(CFPD)show that the proposed network structure achieves 53.68%mean intersection over union(mIoU)and has better performance on the clothing parsing task. 展开更多

Clothing parsing, also known as clothing image segmentation, is the problem of assigning a clothing category label to each pixel in clothing images. To address the lack of positional and global prior in existing clothing parsing algorithms, this paper proposes an enhanced positional attention module(EPAM) to collect positional information in the vertical direction of each pixel, and an efficient global prior module(GPM) to aggregate contextual information from different sub-regions. The EPAM and GPM based residual network(EG-ResNet) could effectively exploit the intrinsic features of clothing images while capturing information between different scales and sub-regions. Experimental results show that the proposed EG-ResNet achieves promising performance in clothing parsing of the colorful fashion parsing dataset(CFPD)(51.12% of mean Intersection over Union(mIoU) and 92.79% of pixel-wise accuracy(PA)) compared with other state-of-the-art methods. 展开更多

In this paper, we present a modular incremental statistical model for English full parsing. Unlike other full parsing approaches in which the analysis of the sentence is a uniform process, our model separates the full parsing into shallow parsing and sentence skeleton parsing. In shallow parsing, we finish POS tagging, Base NP identification, prepositional phrase attachment and subordinate clause identification. In skeleton parsing, we use a layered feature-oriented statistical method. Modularity possesses the advantage of solving different problems in parsing with corresponding mechanisms. Feature-oriented rule is able to express the complex lingual phenomena at the key point if needed. Evaluated on Penn Treebank corpus, we obtained 89.2% precision and 89.8% recall. 展开更多

The present work aims is to propose a solution for automating updates (MAJ) of the radio parameters of the ATOLL database from the OSS NetAct using Parsing. Indeed, this solution will be operated by the RAN (Radio Access Network) service of mobile operators, which ensures the planning and optimization of network coverage. The overall objective of this study is to make synchronous physical data of the sites deployed in the field with the ATOLL database which contains all the data of the coverage of the mobile networks of the operators. We have made an application that automates, updates with the following functionalities: import of radio parameters with the parsing method we have defined, visualization of data and its export to the Template of the ATOLL database. The results of the tests and validations of our application developed for a 4G network have made it possible to have a solution that performs updates with a constraint on the size of data to be imported. Our solution is a reliable resource for updating the databases containing the radio parameters of the network at all mobile operators, subject to a limitation in terms of the volume of data to be imported. 展开更多

The Extensible Markup Language(XML)files,widely used for storing and exchanging information on the web require efficient parsing mechanisms to improve the performance of the applications.With the existing Document Object Model(DOM)based parsing,the performance degrades due to sequential processing and large memory requirements,thereby requiring an efficient XML parser to mitigate these issues.In this paper,we propose a Parallel XML Tree Generator(PXTG)algorithm for accelerating the parsing of XML files and a Regression-based XML Parsing Framework(RXPF)that analyzes and predicts performance through profiling,regression,and code generation for efficient parsing.The PXTG algorithm is based on dividing the XML file into n parts and producing n trees in parallel.The profiling phase of the RXPF framework produces a dataset by measuring the performance of various parsing models including StAX,SAX,DOM,JDOM,and PXTG on different cores by using multiple file sizes.The regression phase produces the prediction model,based on which the final code for efficient parsing of XML files is produced through the code generation phase.The RXPF framework has shown a significant improvement in performance varying from 9.54%to 32.34%over other existing models used for parsing XML files. 展开更多

AIM:To investigate the outcomes and prognosis of macular epiretinal membrane(ERM)after pars plana vitrectomy(PPV)in patients with high myopia(HM),focusing on the optimal timing of surgery and its impact on prognosis.METHODS:The clinical data of 50 eyes from 49 patients diagnosed with ERM,who were highly myopic and underwent PPV were retrospectively analyzed.The patients with ERM were classified into five groups based on the characteristics associated with different levels of myopic traction maculopathy.Group 1:Simple ERM without complex vertical and tangential direction traction on retina on optical coherence tomography(OCT)image;Group 2:ERM with obvious macular foveal schisis,without macular hole(MH);Group 3:ERM with inner lamellar MH,with or without macular foveal schisis;Group 4:ERM with outer lamellar MH,with or without foveal retinal detachment(RD);Group 5:ERM with full-thickness MH.Baseline characteristics,changes in best corrected visual acuity(BCVA)before and after surgery,and anatomical characteristics through spectral domain OCT were compared.RESULTS:The 50 eyes were followed for 6mo,with an average age of 58.66y and an average axial length(AL)of 28.69 mm.Among the five groups,postoperative logMAR BCVA improved(P0.05).OCT showed that Groups 4 and 5 exhibited poorer macular anatomy compared to the other three groups,as evidenced by lower rates of central retinal reattachment(64.3%in Group 4,86.7%in Group 5)and integrity of the inner segment/outer segment of photoreceptor junction(28.6%in Group 4,26.7%in Group 5).CONCLUSION:PPV is an effective treatment for ERM in patients with HM.All groups showed postoperative improvement in BCVA compared to preoperative levels,demonstrating the necessity of surgical intervention.Early intervention,particularly before the fourth stage of the disease,may lead to better visual outcomes. 展开更多
