Knowledge representation and retrieval using conceptual graphs and free text document self-organisation techniques

Conceptual graph formalism for financial text representation

“…CGs are also utilized in software engineering discipline to represent user requirements, build design specification, proposing frameworks and model verification [9]. In the medical field, various medical text are transformed into CGs such as the work reported in [7] and [14], where the CG were used to capture the structure and semantic information contained in free text medical documents.…”

“…It is suitable for a wide range of problems in natural language processing, information retrieval and text mining. There are various other works that have used CG representation to capture the structure and semantic information contained in free text [6][7][8][9][10]. Like numerous other researchers, we are convinced that the financial text can be efficiently represented using conceptual graph formalism.…”

Typological Descriptions as Generative Guides for Historical Architecture

“…An ontology in the context of knowledge management is defined as composed of a domain-specific (expandable) controlled vocabulary, a set of semantic relationships between the terms of the vocabulary, and a set of operators that control how this vocabulary represents the domain objects (Chu and Cesnik 2001). The terms in this vocabulary have various properties assigned.…”

Organization of multimedia data for conceptual search based on ontologies

“…In the literature, several works use a conceptual search to retrieve data in different types of scenario, like medical data [26], texts referring to laws and legal cases [27], images contents [28], source codes [29] and Semantic Web data [30]. Conceptual graphs are also used when the information sought does not exist [31].…”
