The cold-start problem is a long-standing problem in recommender systems, i.e., lack of historical interaction information hinders effective recommendations for new users and items. Existing methods typically incorporate attribute information of users and items to address the strict cold-start problem. Most existing recommendation methods overlook the sparsity of user attributes in cold start recommendation systems. In this paper, we develop a novel framework, Graph Attention Networks with Adaptive Neighbor Graph Aggregation for cold-start Recommendation (A-GAR), which utilizes the user/item relationship information in cold-start recommendation systems to alleviate the sparsity of attributes. we can achieve more accurate recommendations in cold-start scenarios by fully exploring the complex relations between users/items using graph structures. Specifically, to learn the complex relationships between user/item attributes, we utilize SENet (Squeeze and Excitation Network) and MLP (Multilayer Perceptron) networks to adaptively fuse the embeddings of user/item and their second-order interaction vectors, achieving high-order feature aggregation. To address the issue of lacking preference information in cold-start recommendations, we extend the variational autoencoder to reconstruct missing user preferences (item characteristics) from higher-order attribute features of users/items. In order to learn the potential semantic relationships of nodes in the neighbor graph structure, an attribute graph attention network is used to aggregate the neighbor information of users and the interaction information between neighbors. In this way, the high-order relationships between nodes and the potential semantics of adjacent graphs can be fully explored. Extensive experiments on three real-word datasets with various cold-start scenarios demonstrate that A-GAR yields significant improvements for strict cold-start recommendations.

冷启动问题是推荐系统中一个长期存在的问题,即缺乏历史交互信息会阻碍对新用户和新项目的有效推荐。现有方法通常会结合用户和项目的属性信息来解决严格的冷启动问题。大多数现有的推荐方法都忽略了冷启动推荐系统中用户属性的稀缺性。在本文中,我们开发了一个新颖的框架--用于冷启动推荐的自适应邻接图聚合图注意力网络(A-GAR),它利用冷启动推荐系统中的用户/物品关系信息来缓解属性稀疏性问题。我们可以利用图结构充分探索用户/物品之间的复杂关系,从而在冷启动场景中实现更准确的推荐。具体来说,为了学习用户/物品属性之间的复杂关系,我们利用 SENet(挤压和激励网络)和 MLP(多层感知器)网络来自适应地融合用户/物品的嵌入向量及其二阶交互向量,从而实现高阶特征聚合。为了解决冷启动推荐中缺乏偏好信息的问题,我们扩展了变异自动编码器,从用户/物品的高阶属性特征中重建缺失的用户偏好(物品特征)。为了学习邻居图结构中节点的潜在语义关系,我们使用了一个属性图注意力网络来聚合用户的邻居信息和邻居之间的交互信息。这样,节点之间的高阶关系和相邻图的潜在语义就能被充分挖掘出来。在三个具有不同冷启动场景的实词数据集上进行的广泛实验表明,A-GAR 对严格的冷启动推荐有显著的改进。

Predictive Process Monitoring (PPM) is a field of Process Mining that aims at predicting how an ongoing execution of a business process will develop in the future using past process executions recorded in event logs. The recent stream of publications in this field shows the need for tools able to support researchers and users in comparing and selecting the techniques that are the most suitable for them. In this paper, we present Nirdizati , a dedicated tool for supporting users in building, comparing and explaining the PPM models that can then be used to perform predictions on the future of an ongoing case. Nirdizati has been constructed by carefully considering the necessary capabilities of a PPM tool and by implementing them in a client-server architecture able to support modularity and scalability. The features of Nirdizati support researchers and practitioners within the entire pipeline for constructing reliable PPM models. The assessment using reactive design patterns and load tests provides an evaluation of the interaction among the architectural elements, and of the scalability with multiple users accessing the prototype in a concurrent manner, respectively. By providing a rich set of different state-of-the-art approaches, Nirdizati offers to Process Mining researchers and practitioners a useful and flexible instrument for comparing and selecting PPM techniques.

Group recommendation systems are widely applied in social media, e-commerce, and diverse platforms. These systems face challenges associated with data privacy constraints and protection regulations, impeding the sharing of user data for model improvement. To address the issue of data silos, federated learning emerges as a viable solution. However, difficulties arise due to the non-independent and non-identically distributed nature of data across different platforms, affecting performance. Furthermore, conventional federated learning often overlooks individual differences among stakeholders. In response to these challenges, we propose a pioneering cross-platform federated group recommendation system named FedGR. FedGR integrates hypergraph convolution, attention aggregation, and fully connected fusion components with federated learning to ensure exceptional model performance while preserving the confidentiality of private data. Additionally, we introduce a novel federated model aggregation strategy that prioritizes models with high training effectiveness, thereby improving overall model performance. To address individual differences, we design a temporal personalization update strategy for updating item representations, allowing local models to focus more on their individual characteristics. To evaluate FedGR, we apply our approach to three real-world datasets, demonstrating the robust capabilities of our cross-platform group recommendation system.

群组推荐系统广泛应用于社交媒体、电子商务和各种平台。这些系统面临着与数据隐私限制和保护法规相关的挑战,阻碍了为改进模型而共享用户数据。为了解决数据孤岛问题,联合学习成为一种可行的解决方案。然而,由于数据在不同平台上的非独立性和非同分布性,会影响性能,因此出现了一些困难。此外,传统的联合学习往往忽略了利益相关者之间的个体差异。为了应对这些挑战,我们提出了一个名为 FedGR 的开创性跨平台联合群体推荐系统。FedGR 将超图卷积、注意力聚合和全连接融合组件与联合学习集成在一起,确保了卓越的模型性能,同时保护了私人数据的机密性。此外,我们还引入了一种新颖的联合模型聚合策略,该策略优先考虑训练效率高的模型,从而提高了模型的整体性能。为解决个体差异问题,我们设计了一种用于更新项目表征的时态个性化更新策略,使局部模型更专注于其个体特征。为了对 FedGR 进行评估,我们将我们的方法应用于三个真实数据集,展示了我们跨平台群体推荐系统的强大功能。

The COVID-19 Numerical Claims Open Research Dataset (CONCORD) is a comprehensive, open-source dataset that extracts numerical claims from academic papers on COVID-19 research. A weak-supervision model is employed for this extraction, taking advantage of its white-box, explainable nature and reduced computational and annotation costs compared to transformer-based models. This model uses labelling functions such as pattern matching, external knowledge bases, phrase matching, and third-party models to generate labels, with an aggregator function handling contradictory labels. Evaluated against established baselines, the model achieved a weighted F1-score of 0.932 and a micro F1-score of 0.930. While transformer-based models achieve comparable results, the explainability of weak-supervision offers distinct advantages. Additionally, generative LLMs were tested to understand their effectiveness in extracting numerical claims, highlighting the impact of prompt engineering on performance. CONCORD contains approximately 200,000 numerical claims from over 57,000 COVID-19 research articles, serving as a valuable resource for tracking developments in COVID-19 research. This dataset, coupled with the weak-supervision approach, provides researchers with a significant tool for advancing COVID-19 research and showcases the potential of these methodologies in the broader biomedical field.

COVID-19 数字索赔开放研究数据集(CONCORD)是一个全面的开源数据集,可从有关 COVID-19 研究的学术论文中提取数字索赔。与基于转换器的模型相比,CONCORD 采用了弱监督模型,利用其白盒、可解释的特性,降低了计算和注释成本。该模型使用模式匹配、外部知识库、短语匹配和第三方模型等标签功能生成标签,并使用聚合器功能处理相互矛盾的标签。根据既定基线进行评估,该模型的加权 F1 分数为 0.932,微 F1 分数为 0.930。虽然基于转换器的模型取得了不相上下的结果,但弱监督的可解释性具有明显的优势。此外,我们还对生成式 LLM 进行了测试,以了解它们在提取数字主张方面的有效性,从而突出提示工程对性能的影响。CONCORD 包含了来自 57,000 多篇 COVID-19 研究文章中的约 200,000 条数值声明,是跟踪 COVID-19 研究发展的宝贵资源。该数据集与弱监督方法相结合,为研究人员提供了推进 COVID-19 研究的重要工具,并展示了这些方法在更广泛的生物医学领域的潜力。

DA-BAG: A multi-model fusion text classification method combining BERT and GCN using self-domain adversarial training DA-BAG:利用自域对抗训练结合 BERT 和 GCN 的多模型融合文本分类方法
IF 3.4 3区 计算机科学 Q3 COMPUTER SCIENCE, ARTIFICIAL INTELLIGENCE Pub Date : 2024-09-16 DOI: 10.1007/s10844-024-00889-2

Pre-training-based methods are considered some of the most advanced techniques in natural language processing tasks, particularly in text classification. However, these methods often overlook global semantic information. In contrast, traditional graph learning methods focus solely on structured information from text to graph, neglecting the hidden local information within the syntactic structure of the text. When combined, these approaches may introduce new noise and training biases. To tackle these challenges, we introduce DA-BAG, a novel approach that co-trains BERT and graph convolution models. Utilizing a self-domain adversarial training method on a single dataset, DA-BAG extracts multi-domain distribution features across multiple models, enabling self-adversarial domain adaptation training without the need for additional data, thereby enhancing model generalization and robustness. Furthermore, by incorporating an attention mechanism in multiple models, DA-BAG effectively combines the structural semantics of the graph with the token-level semantics of the pre-trained model, leveraging hidden information within the text’s syntactic structure. Additionally, a sequential multi-layer graph convolutional neural(GCN) connection structure based on a residual pre-activation variant is employed to stabilize the feature distribution of graph data and adjust the graph data structure accordingly. Extensive evaluations on 5 datasets(20NG, R8, R52, Ohsumed, MR) demonstrate that DA-BAG achieves state-of-the-art performance across a diverse range of datasets.

基于预训练的方法被认为是自然语言处理任务中最先进的技术,尤其是在文本分类方面。然而,这些方法往往忽略了全局语义信息。相比之下,传统的图学习方法只关注从文本到图的结构信息,而忽略了文本句法结构中隐藏的局部信息。当这些方法结合在一起时,可能会引入新的噪声和训练偏差。为了应对这些挑战,我们引入了 DA-BAG,这是一种共同训练 BERT 和图卷积模型的新方法。DA-BAG 利用单个数据集上的自域对抗训练方法,在多个模型中提取多域分布特征,无需额外数据即可进行自对抗域适应训练,从而增强了模型的泛化和鲁棒性。此外,通过在多个模型中加入注意力机制,DA-BAG 有效地将图的结构语义与预训练模型的标记级语义相结合,充分利用了文本句法结构中的隐藏信息。此外,DA-BAG 还采用了基于残差预激活变体的序列多层图卷积神经(GCN)连接结构,以稳定图数据的特征分布,并相应地调整图数据结构。在 5 个数据集(20NG、R8、R52、Ohsumed、MR)上进行的广泛评估表明,DA-BAG 在各种数据集上都取得了最先进的性能。

Recommendation systems play a major role in modern music streaming platforms, assisting consumers in finding new music that suits their tastes. However, a significant challenge persists when it comes to recommending new songs that lack historical data. This study introduces a Content based Attentive Sequential Recommendation Model (CASRM) that deals with item cold start issue and recommends relevant and fresh music using Gated Graph Neural Networks (GNNs). Music metadata such as artists, albums, genres, and tags are included in the content information, along with context data incorporating user behaviour such as sessions, listening logs, and music playing sequences. By representing the music data as a graph, we can effectively capture the intricate relationships between songs and users. To capture users’ music preferences, we analyse their interactions with songs within the sessions. We incorporate content-based item embeddings for newly added items, enabling personalized recommendations for new songs based on their characteristics and similarities to the songs listened by users in the past. Specifically, we examined the proposed model on three distinct datasets, and the experimental outcomes show its efficacy in predicting music ratings for new songs. Compared to other baseline methods, the CASRM model achieves superior performance in providing accurate and diverse music recommendations in cold-start scenarios.

推荐系统在现代音乐流媒体平台中发挥着重要作用,它可以帮助消费者找到适合自己口味的新音乐。然而,在推荐缺乏历史数据的新歌曲时,仍然存在着巨大的挑战。本研究介绍了一种基于内容的贴心顺序推荐模型(CASRM),它能解决项目冷启动问题,并使用门控图神经网络(GNNs)推荐相关的新鲜音乐。内容信息中包括艺术家、专辑、流派和标签等音乐元数据,以及包含会话、收听记录和音乐播放顺序等用户行为的上下文数据。通过将音乐数据表示为图形,我们可以有效捕捉歌曲和用户之间错综复杂的关系。为了捕捉用户的音乐偏好,我们分析了他们在会话中与歌曲的互动。我们为新添加的项目加入了基于内容的项目嵌入,从而根据新歌曲的特点以及与用户过去所听歌曲的相似性,为用户提供个性化推荐。具体来说,我们在三个不同的数据集上检验了所提出的模型,实验结果表明该模型在预测新歌曲的音乐评分方面非常有效。与其他基线方法相比,CASRM 模型在冷启动场景下提供准确且多样化的音乐推荐方面表现出色。

Detecting bipolar disorder on social media by post grouping and interpretable deep learning 通过帖子分组和可解释深度学习检测社交媒体上的躁郁症
IF 3.4 3区 计算机科学 Q3 COMPUTER SCIENCE, ARTIFICIAL INTELLIGENCE Pub Date : 2024-09-11 DOI: 10.1007/s10844-024-00884-7

Bipolar disorder is a disorder in which a person expresses manic and depressed emotions repeatedly. Diagnosing bipolar disorder accurately can be difficult because other mood disorders or even regular mood changes may have similar symptoms. Therefore, psychiatrists need to spend a long time observing and interviewing clients to make the diagnosis. Recent studies have trained machine learning models for detecting bipolar disorder on social media. However, most of these studies focused on increasing the accuracy of the model without explaining the classification results. Although the posts of a bipolar disorder user can be observed manually, doing so is not practical since a user can have many posts which may not depict any signs of bipolar disorder. Without any explanations, the trustworthiness of the model decreases. We propose a deep learning model that not only detects and classifies bipolar disorder users but also explains how the model generates the classification results. The posts are first grouped using Latent Dirichlet Allocation, a method commonly used to classify the topic of a text. These groups are then input into the model, and attention mechanisms are utilized to determine which groups have more attention weights and are considered more heavily. Finally, an explanation of the classification results is obtained by visualizing the attention weights.

躁郁症是一种反复出现躁狂和抑郁情绪的疾病。准确诊断躁郁症可能很困难,因为其他情绪障碍甚至是正常的情绪变化都可能有类似的症状。因此,精神科医生需要花很长时间观察和询问患者,才能做出诊断。最近的研究已经训练了机器学习模型来检测社交媒体上的双相情感障碍。然而,这些研究大多侧重于提高模型的准确性,而没有解释分类结果。虽然可以手动观察躁郁症用户的帖子,但这样做并不实际,因为一个用户可能有很多帖子,但这些帖子可能没有描述任何躁郁症的迹象。没有任何解释,模型的可信度就会降低。我们提出的深度学习模型不仅能检测和分类躁郁症用户,还能解释模型如何生成分类结果。首先使用 Latent Dirichlet Allocation 对帖子进行分组,这是一种常用于对文本主题进行分类的方法。然后将这些分组输入模型,并利用注意力机制来确定哪些分组有更多的注意力权重,并更多地考虑这些分组。最后,通过可视化注意力权重来解释分类结果。我们介绍了几个案例研究,以展示我们提出的模型所产生的解释。我们的模型还与其他模型进行了比较,取得了 F1-Score 0.92 的最佳性能。

Diagnosing bipolar disorder accurately can be difficult because other mood disorders or even regular mood changes may have similar symptoms. Therefore, psychiatrists need to spend a long time observing and interviewing clients to make the diagnosis. Recent studies have trained machine learning models for detecting bipolar disorder on social media. However, most of these studies focused on increasing the accuracy of the model without explaining the classification results. Although the posts of a bipolar disorder user can be observed manually, doing so is not practical since a user can have many posts which may not depict any signs of bipolar disorder. Without any explanations, the trustworthiness of the model decreases. We propose a deep learning model that not only detects and classifies bipolar disorder users but also explains how the model generates the classification results. The posts are first grouped using Latent Dirichlet Allocation, a method commonly used to classify the topic of a text. These groups are then input into the model, and attention mechanisms are utilized to determine which groups have more attention weights and are considered more heavily.

Forest tree dieback inventory has a crucial role in improving forest management strategies. This inventory is traditionally performed by forests through laborious and time-consuming human assessment of individual trees. On the other hand, the large amount of Earth satellite data that are publicly available with the Copernicus program and can be processed through advanced deep learning techniques has recently been established as an alternative to field surveys for forest tree dieback tasks. However, to realize its full potential, deep learning requires a deep understanding of satellite data since the data collection and preparation steps are essential as the model development step. In this study, we explore the performance of a data-centric semantic segmentation approach to detect forest tree dieback events due to bark beetle infestation in satellite images. The proposed approach prepares a multisensor data set collected using both the SAR Sentinel-1 sensor and the optical Sentinel-2 sensor and uses this dataset to train a multisensor semantic segmentation model. The evaluation shows the effectiveness of the proposed approach in a real inventory case study that regards non-overlapping forest scenes from the Northeast of France acquired in October 2018. The selected scenes host bark beetle infestation hotspots of different sizes, which originate from the mass reproduction of the bark beetle in the 2018 infestation.

林木枯死情况清查对于改进森林管理策略至关重要。传统上,森林部门需要对单棵树木进行费时费力的人工评估。另一方面,哥白尼计划公开提供了大量地球卫星数据,这些数据可通过先进的深度学习技术进行处理,最近已被确定为林木枯死任务实地调查的替代方法。然而,要充分发挥深度学习的潜力,需要对卫星数据有深入的了解,因为数据收集和准备步骤与模型开发步骤一样至关重要。在本研究中,我们探索了一种以数据为中心的语义分割方法的性能,以检测卫星图像中因树皮甲虫侵袭而导致的林木枯死事件。所提出的方法准备了一个利用合成孔径雷达哨兵-1 传感器和光学哨兵-2 传感器收集的多传感器数据集,并使用该数据集来训练一个多传感器语义分割模型。评估显示了所提方法在实际清单案例研究中的有效性,该案例研究涉及 2018 年 10 月从法国东北部获取的非重叠森林场景。所选场景包含不同大小的树皮甲虫侵扰热点,这些热点源于 2018 年侵扰中树皮甲虫的大规模繁殖。

Crowdfunding has evolved into a formidable mechanism for collective financing, challenging traditional funding sources such as bank loans, venture capital, and private equity with its global reach and versatile applications across various sectors. This paper explores the complex dynamics of crowdfunding platforms, particularly focusing on investor behaviour and investment patterns within equity and lending campaigns in Italy. By leveraging advanced machine learning techniques, including XGBoost and LSTM networks, we develop predictive models that dynamically analyze real-time and historical data to accurately forecast the success or failure of crowdfunding campaigns. To address the existing gaps in crowdfunding analysis tools, we introduce two novel datasets—one for equity crowdfunding and another for lending. Moreover, our approach extends beyond traditional binary success metrics, proposing novel measures. The insights gained from this study could support crowdfunding strategies, significantly improving project selection and promotional tactics on platforms. By enhancing decision-making processes and providing forward-looking guidance to investors, our computational model aims to empower both campaign creators and platform administrators, ultimately improving the overall efficacy and sustainability of crowdfunding as a financing tool.

众筹已发展成为一种强大的集体融资机制,凭借其全球影响力和在各行各业的广泛应用,对银行贷款、风险资本和私募股权等传统资金来源构成了挑战。本文探讨了众筹平台的复杂动态,尤其关注意大利股权和借贷活动中的投资者行为和投资模式。通过利用先进的机器学习技术(包括 XGBoost 和 LSTM 网络),我们开发了可动态分析实时和历史数据的预测模型,以准确预测众筹活动的成败。为了弥补众筹分析工具的现有不足,我们引入了两个新颖的数据集,一个是股权众筹数据集,另一个是借贷数据集。此外,我们的方法超越了传统的二元成功指标,提出了新的衡量标准。从这项研究中获得的洞察力可以支持众筹战略,极大地改进项目选择和平台推广策略。通过加强决策过程并为投资者提供前瞻性指导,我们的计算模型旨在增强活动创建者和平台管理者的能力,最终提高众筹作为一种融资工具的整体效率和可持续性。

Deep learning approaches to lexical simplification: A survey 词法简化的深度学习方法:调查
IF 3.4 3区 计算机科学 Q3 COMPUTER SCIENCE, ARTIFICIAL INTELLIGENCE Pub Date : 2024-09-02 DOI: 10.1007/s10844-024-00882-9

Lexical Simplification (LS) is the task of substituting complex words within a sentence for simpler alternatives while maintaining the sentence’s original meaning. LS is the lexical component of Text Simplification (TS) systems with the aim of improving accessibility to various target populations such as individuals with low literacy or reading disabilities. Prior surveys have been published several years before the introduction of transformers, transformer-based large language models (LLMs), and prompt learning that have drastically changed the field of NLP. The high performance of these models has sparked renewed interest in LS. To reflect these recent advances, we present a comprehensive survey of papers published since 2017 on LS and its sub-tasks focusing on deep learning. Finally, we describe available benchmark datasets for the future development of LS systems.

词法简化(LS)是指在保持句子原意的前提下,将句子中的复杂词语替换为更简单的替代词语。LS 是文本简化(TS)系统中的词法部分,目的是提高各种目标人群(如识字率低或有阅读障碍的个人)的可访问性。在引入转换器、基于转换器的大型语言模型(LLMs)以及迅速学习之前的几年,已经发表了一些先前的调查报告,这些调查报告极大地改变了 NLP 领域。这些模型的高性能再次激发了人们对语言学习的兴趣。为了反映这些最新进展,我们对 2017 年以来发表的关于 LS 及其子任务的论文进行了全面调查,重点关注深度学习。最后,我们介绍了用于 LS 系统未来发展的可用基准数据集。
