With the fast growth of World Wide Web 2.0, a great number of opinions about a variety of products have been published in blogs, forums, and social networks. Opinion mining tools are needed to enable users to efficiently process a large number of reviews found online, in order to determine the underlying opinions. This paper presents a new methodology for semantic modelling of the domain knowledge...
Information security contains many concepts and knowledge entities. As the development of information technology, the complexity of increasing information security knowledge need an overview representation and organization for security analysis and risk evaluation. Ontology as a formal and shareable semantic model, which is often used to define domain knowledge schema, can also be applied for information...
Ontologies have been frequently employed in order to solve problems derived from the management of shared distributed knowledge and the efficient integration of information across different applications. However, the process of ontology building is still a lengthy and error-prone task. Therefore, a number of research studies to (semi-)automatically build ontologies from existing documents have been...
To design the methods of textual information authenticity controlling in systems of electronic document circulation authors offered the new approaches based on application the fuzzy semantic hyphernet and use of statistical and structural information redundancy. The models, algorithms and programmed-sold modules of text processing authenticity controlling system are developed for extraction of structural...
Every research field (domain) has a lot of data or information in textual format. The main problem is how to optimally arrange and transform the textual data or information to explore research issues. The authors propose a framework that may help in exploration of research issues from text of specific field (domain). First textual data or information is transformed to semantic network by using some...
This paper investigates the independence relation of concepts and its application to conceptual modeling which is important for knowledge engineering and software engineering of today. Four possible (collectively exhaustive and mutually exclusive) basic relations of two concepts are given and analyzed, whereby the notion of independence relation is introduced. Formalism for the independence of concepts...
