Research ArticleOpen accessIn the abstractRadial Basis Function Neural Networks Towards Electronic Trust QuantificationSmitha Zacaria, Tiny du ToitTrust is a broad term applicable in various contexts. Trust between electronic entities is complex to quantify, particularly in intricate networks. Traditional trust algorithms rely on historical trust values, requiring storage and access to past transaction details. Contextual variations further complicate trust calculation. Challenges in calculating trust include heightened computational complexities, managing information storage, and securing access to extensive datasets … …Journal of Computer Science, Vol. 20, Issue 11 · 26 Sep 2024 · 4,791 accessesView PDFCite
Research ArticleOpen accessIn the abstractComplex SQL-NoSQL Query Translation for Data Lake ManagementNurhadi, Rabiah Abdul Kadir, Ely Salwana Mat SurinA data lake refers to an extremely large data resource or repository. Data lakes store large amounts of data and use advanced analytics to pair data from multiple sources with different types of structured, semi-structured, and unstructured information. NoSQL databases such as Mongodb, Redis, Neo4j, and Cassandra are nontabular and they store data differently rather than use relational tables. NoSQL … …Journal of Computer Science, Vol. 18, Issue 12 · 19 Dec 2022 · 9,277 accessesView PDFCite
Research ArticleOpen accessIn the abstractSQL Generation from Natural Language: A Sequence-to-Sequence Model Powered by the Transformers Architecture and Association RulesYoussef Mellah, Abdelkader Rhouati, El Hassane Ettifouri et al.Using Natural Language (NL) to interacting with relational databases allows users from any background to easily query and analyze large amounts of data. This requires a system that understands user questions and automatically converts them into structured query language such as SQL. The best performing Text-to-SQL systems use supervised learning (usually formulated as a classification problem) by approaching this task … …Journal of Computer Science, Vol. 17, Issue 5 · 23 May 2021 · 10,027 accessesView PDFCite
Research ArticleOpen accessIn the abstractRetrieval Optimization Technique for Tuple Timestamp Historical Relation Temporal Data ModelSami M. Halawani, Ibrahim AlBidewi, Ab Rahman Ahmad, Nashwan A. Al-RomemaProblem statement: In the field of database technology, Recoding time related data are referred to as temporal databases. Conventional relational databases are queried using the underlying constructs of SQL which are translated into Relational Algebra (RA). Relational Algebra (RA) is the writing of logical expressions that uses a set of relational operators to perform operations on specific relation(s) and returns … …Journal of Computer Science, Vol. 8, Issue 2 · 9 Dec 2011 · 7,376 accessesView PDFCite
Research ArticleOpen accessIn the abstractRole of Information Technology Infrastructure Library in Data WarehousesTariq Rahim Soomro, Hasan Yousef WahbaProblem statement: The Information Technology Infrastructure Library (ITIL) is most widely used de-facto- standard, consists of set of concepts and practices for Information Technology Service Management (ITSM), IT development and IT operations. Approach: Where as a Data Warehouse (DW) is a relational database used for the purpose of query and analysis to generate complex reports for enterprises. Results: This study … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 2 Nov 2011 · 7,769 accessesView PDFCite
Research ArticleOpen accessIn the abstractSocio-Economic Statues and Physical Activity Levels of 3th Grade Students: A Case Study in Istanbul Beykoz ProvincePinar Salih, Kucuk Yetgin Meral, Kaya Fatih et al.Problem statement: The children and adolescent period is critical time to acquire positive lifestyle habits. The aim of this study is to investigate the physical activity level of children aged between 9-10 accordance with their BMI’s and socio-economic level of their school environments. This study also reviewed the articles about physical activity level of children, its relation to their socio-economic … …Journal of Social Sciences, Vol. 7, Issue 3 · 16 Jul 2011 · 8,672 accessesView PDFCite
Research ArticleOpen accessIn the abstractExtension and Prerequisite: An Algorithm to Enable Relations Between Responses in Chatbot TechnologyAbbas Saliimi Lokman, Jasni Mohamad ZainProblem statement: Artificial intelligence chatbot is a technology that makes interactions between man and machines using natural language possible. From literature, we found out that in general, chatbot are functions like a typical search engine. Although chatbot just produced only one output instead of multiple outputs/results, the basic process flow is the same where each time an input is entered, … …Journal of Computer Science, Vol. 6, Issue 10 · 24 Aug 2010 · 16,993 accessesView PDFCite
Research ArticleOpen accessIn the abstractSummarizing Relational Data Using Semi-Supervised Genetic Algorithm-Based Clustering TechniquesRayner AlfredProblem statement: In solving a classification problem in relational data mining, traditional methods, for example, the C4.5 and its variants, usually require data transformations from datasets stored in multiple tables into a single table. Unfortunately, we may loss some information when we join tables with a high degree of one-to-many association. Therefore, data transformation becomes a tedious trial-and-error work and … …Journal of Computer Science, Vol. 6, Issue 7 · 31 Jul 2010 · 7,585 accessesView PDFCite
Research ArticleOpen accessIn the abstractDifferential Diagnosis Knowledge Building by Using CUC-C4.5 FrameworkKusrini, Sri Hartati, Retantyo Wardoyo, Agus HarjokoProblem statement: The Case Based Reasoning (CBR) method can be implemented in differential diagnosis analysis. C4.5 algorithm has been commonly used to help the method's knowledge building process. This process is completed by constructing decision tree from previously handled cases data. The C4.5 algorithm itself can be used with an assumption that all the cases has an exact and equal … …Journal of Computer Science, Vol. 6, Issue 2 · 28 Feb 2010 · 8,411 accessesView PDFCite
Research ArticleOpen accessIn the abstractDiscretization Numerical Data for Relational Data with One-to-Many RelationsRayner AlfredProblem statement: Handling numerical data stored in a relational database has been performed differently from handling those numerical data stored in a single table due to the multiple occurrences (one-to-many association) of an individual record in the non-target table and non-determinate relations between tables. Numbers in Multi-Relational Data Mining (MRDM) were often discretized, after considering the schema of the relational … …Journal of Computer Science, Vol. 5, Issue 7 · 31 Jul 2009 · 7,030 accessesView PDFCite
