Conceptual models can support the description and explanation of the genome’s elaborate structure and behavior. Among others, the Conceptual Schema of the Human Genome (CSG) provides a <em>concept-oriented, top-down</em> representation of the genome behavior, which is independent of data formats. The Genomic Conceptual Model (GCM) provides instead a <em>data-oriented, bottom-up</em> representation, targeting a well-organized, unified description of these formats. In this research, we join the two approaches to achieve PoliViews, a comprehensive model that links (1) a <em>concepts layer</em>, describing genome elements and their conceptual connections, with (2) a <em>data layer</em>, describing datasets derived from genome sequencing with specific technologies. Their dynamic connection is established when specific genomic data types are chosen in the data layer, thereby triggering the selection of a view in the concepts layer. The benefit is mutual: data records can be semantically described by high-level concepts exploiting their links and, in turn, the continuously evolving abstract model can be extended thanks to the input provided by real datasets. PoliViews enables expressing queries that employ a holistic conceptual perspective on the genome, directly translated onto data-oriented terms and organization. Here, we demonstrate the approach by linking two major genomic data types, namely DNA variation and gene expression. For each type, we consider different eminent data sources; we describe their mapping with the corresponding view in the concepts layer, enabling an <em>intra-data-type</em> integration. Then, leveraging on the connections available in the concepts layer, we show how the distinct data types can be interoperated, enabling an <em>inter-data-type</em> integration. The PoliViews approach is shown through several examples of biological interest and can be further extended to any kind of genomic information.</p></div>","PeriodicalId":55184,"journal":{"name":"Data & Knowledge Engineering","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49767444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although in several applications the user aims to detect data objects that have values as good as possible in <em>all</em> specified criteria, skyline queries fail to identify only those objects. Instead, objects whose values are good in a subset of the given criteria are also included in the skyline set, even though they may take arbitrarily bad values in the remaining criteria. To alleviate this shortcoming, we study the decisive subspaces that express the semantics of skyline points and determine skyline membership. We propose a novel alternative query, called <em>decisive skyline query</em>, which retrieves a set of points that balance all specified criteria. We study two variants of the proposed query, the <em>strict</em> variant, which retrieves only the subset of skyline points that have the full data space as decisive subspace, and the <em>relaxed</em> variant, which imposes the decisive semantics in a more flexible way. Furthermore, we present pruning properties that accelerate the process of finding the decisive skyline set. Capitalizing on these pruning properties, we propose a novel efficient algorithm for computing decisive skyline points. Our experimental study, which employs both synthetic and real data sets for various experimental setups, demonstrates the efficiency and effectiveness of our algorithm, and shows that the newly proposed query is more intuitive and informative for the user.</p></div>","PeriodicalId":55184,"journal":{"name":"Data & Knowledge Engineering","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49767446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, there is a need for a system that automatically extracts the information of interest from the resumes. Such automatic extraction of information from resumes is very challenging because resumes are unstructured documents with a wide range of variations in terms of format, style, and contents. In this paper, we describe RINX (<strong>R</strong>esume <strong>IN</strong>formation e<strong>X</strong>traction) which is an end-to-end system for automatic extraction of information from resumes.

Case Pendency is a long-lasting problem in many countries. The judicial system has to be more competent and reliable to provide justice on time for any developing country. Litigants and attorneys devote more time and effort to trial case preparation in the courtroom. The task of decision prediction is to automatically forecast the type of charge, law article, and term of punishment. Most of the earlier works for verdict prediction focused to work on civil law jurisdictions. Some of the challenges in the task are case facts are highly unstructured lengthy documents with a lack of annotations and mainly used machine learning techniques. While most research works ignore the information loss at the encoding stage, our proposed MHAN overcomes the above issue and long-range dependency problem using the attention model over hierarchical encoders with three tiers namely Sentence encoder, word encoder, and character encoder. To avoid information loss, a brand-new judgment prediction framework called MHAN is developed in this study effort. It is built on a modified Hierarchical-Attention network and a specially designed domain-specific word embedding model. Additionally, it emphasizes the feature extraction phase by joining features obtained using MHAN with an improved cosine similarity feature. Finally, a hybrid Self Improved RNN is employed to provide the projected results. Furthermore, the proposed model is trained on 10 types of real-time criminal cases from the Madras High Court of India and Supreme Court of India. It has outperformed prior methods in terms of verdict prediction. By applying different variations of the deep learning model and ablation tests, the proposed model achieves consistent results over baseline models.</p></div>","PeriodicalId":55184,"journal":{"name":"Data & Knowledge Engineering","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49753049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Chinese government enacted a series of policies to restrict the transportation industry in order to slow the spread of the COVID-19 virus in early 2020. With the gradual control of the COVID-19 epidemic and the reduction of confirmed cases, the Chinese transportation industry has gradually recovered. The traffic revitalization index is the main indicator for evaluating the degree of recovery of the urban transportation industry after being affected by the COVID-19 epidemic. The prediction research of traffic revitalization index can help the relevant government departments to know the state of urban traffic from the macro level and formulate relevant policies. Therefore, this study proposes a deep spatial–temporal prediction model based on tree structure for the traffic revitalization index. The model mainly includes spatial convolution module, temporal convolution module and matrix data fusion module. The spatial convolution module builds a tree convolution process based on the tree structure that can contain directional features and hierarchical features of urban nodes. The temporal convolution module constructs a deep network for capturing temporal dependent features of the data in the multi-layer residual structure. The matrix data fusion module can perform multi-scale fusion of COVID-19 epidemic data and traffic revitalization index data to further improve the prediction effect of the model.
