Modeling imprecise requirements with XML

Jonathan Lee, Yong-Yi Fanjiang
2003 Information and Software Technology  
In this paper, we have developed a fuzzy object-oriented modeling technique (FOOM) schema based on XML to model requirements specifications and incorporated the notion of stereotype to facilitate the modeling  ...  A schema graph is proposed to serve as an intermediate representation for the structure of FOOM schema to bridge the FOOM schema and APIs for both content validation and data access for the XML documents  ...  We formally describe the details on how to establish a schema graph from an XML schema in Algorithm 1.  ...

A Fuzzy Extension for the XPath Query Language [chapter]

Alessandro Campi, Sam Guinea, Paola Spoletini
2006 Lecture Notes in Computer Science  
In this paper we describe a XML querying framework, called FuzzyXPath, based on Fuzzy Set Theory, relying on fuzzy conditions for the definition of flexible constraints on stored data.  ...  Its goal is to provide a degree of similarity between two XML trees, assessing whether they are similar both structure-wise and content-wise.  ...  document structure from the schema.  ...

An Algebra for Fuzzy Spatiotemporal Data in XML

Luyi Bai, Lin Zhu
2019 IEEE Access  
A formal algebra is essential for applying standard database-style query optimization to XML queries. We develop such algebra for manipulating fuzzy spatiotemporal XML data.  ...  It shows that the algebra can lay a firm foundation for managing fuzzy spatiotemporal XML data. INDEX TERMS Algebra, fuzzy spatiotemporal data, XML.  ...  As evidenced by the successful relational technology [14] , a formal algebra is absolutely essential for applying standard database-style query optimization to XML queries.  ...

Evaluations of Conceptual Models for Semi-structured Database System

Rita Ganguly, Anirban Sarkar
2012 International Journal of Computer Applications  
Research about similarity between semi structured documents (particularly for XML documents) has produced many works in the areas of Database Systems, Artificial Intelligence and Data Mining.  ...  In the latest years many different models for semi structured data have been proposed; most of them, however, are too specific to allow immediate comparison with other models, and do not easily support  ...  the capability to automatically generate XML document type definitions and schema from such structures.  ...

Bottom-Up Extraction and Trust-Based Refinement of Ontology Metadata

Paolo Ceravolo, Ernesto Damiani, Marco Viviani
2007 IEEE Transactions on Knowledge and Data Engineering  
Our rough bottom-up ontologies are based on simple relations like association and inheritance, as well as on value restrictions, and can be used to enrich and update existing upper ontologies.  ...  We present a way of building ontologies that proceeds in a bottom-up fashion, defining concepts as clusters of concrete XML objects.  ...  Our XML content can belong to one of the basic XML Schema data-types (URLs, numbers, dates, etc.) or be a text blob.  ...

Fuzzy set theoretical approach to document retrieval

Tadeusz Radecki

Conceptual Design of Document NoSQL Database with Formal Concept Analysis

2016 Acta Polytechnica Hungarica  
In this paper we will explore a method for the conceptual modeling for document based databases, using Formal Concept Analysis (FCA).  ...  We have shown that FCA is a valuable visual analyzer for large-scale data, for example, offering a means of reading the possibility of nested scheme design from the built concept lattice.  ...  In [14] we have shown that an XML database can be translated into a power context family and that the functional dependencies of such a database correspond to FCA implications in a certain formal context  ...

Securing Financial XML Transactions Using Intelligent Fuzzy Classification Techniques [chapter]

Faisal Tawfiq Ammari, Joan Lu
2020 Securing the Internet of Things  
The results obtained from our experiments are promising, showing that our model can provide an effective yet resilient support for financial systems to secure exchanged financial XML messages.  ...  Upon fuzzy classification phase, a unique value is assigned to a defined attribute named "Importance Level". Assigned value indicates the data sensitivity for each XML tag.  ...  Further, the author developed the formal conversions from the fuzzy UML model to the fuzzy XML model, as well as the formal mapping from the fuzzy XML model to fuzzy relational databases.  ...

XML-based requirements engineering for an electronic clearinghouse

Mariusz A. Fecko, Christopher M. Lott
2005 Information and Software Technology  
Fourth, we developed translators from the structured requirements to schema languages, which enabled automated generation of message-validation code.  ...  To remedy the resulting software failures and faults, we first formalized the requirements by designing an W3C XML Schema for the precise definition of the requirements structure.  ...  Acknowledgements We would like to thank the clearinghouse management team, the Applied Research management team, and our colleagues for their support and encouragement:  ...

It will then discuss the relation between tm and machine translation (mt) as well as ways of integrating the two types of translation technologies.  ...  They have become the major language technology to support the translation and localization industries.  ...  For proprietary xml-based formats, tm systems should provide a feature to create import routines from a combination of various sources, i.e. xml document type definitions (dtds), xml schema definition  ...
