- The Role of Frame-Based Representation on the Semantic Web (O. Lassila, D. McGuinness, 2001). The first is an introductory text and informative, and quoted widely, perfect to get an overview of the issue, which I would like to highlight especially the chapter "Knowledge Representation" by be closely related to topic covered in the second text. In "The Role of ..." the authors propose the scheme of knowledge representation (KR
) based in frames (frame-based representation ) as a paradigm for building ontology-necessary in its opinion for the construction of the semantic web - and for the conceptualization of formal language
] [3 ] [ 4] [5 ] proposed for this purpose as a basic scheme for WWW Consortium as an expression of frame-based representation of one's own WWW
.- frame-based representation is a type of formal representation knowledge derived from the overall scheme of semantic networks (see specifically the chapter "4.3.2.3 Schemes frames" within the link text.) On the other hand, semantic networks are a widely used mechanism for representation in the field of Artificial Intelligence (AI). Introduction In this Artificial Intelligence is offered, along with a general historical perspective IA, a good theoretical approach to the formal models of knowledge representation and application domains: see in particular paragraphs
- simple models of general purpose symbolic , Domain knowledge and its fragmentation
distribution of knowledge. The knowledge representation scheme based on frames was proposed initially by MIT professor Marvin Minsky -pioneer IA, the neuro-cognitive sciences , and linguistics computing, including disciplines, in his essay A Framework for Representing Knowledge (1974). In any case, as illustrative of the difficulty of the practice of knowledge representation and information retrieval, metadata [ 1] [2 ] to be accurate-in the environment semantic web, nothing better than reading about the article by Peter Manuel Díaz Ortuño Issues and trends in web metadata architecture ( PDF
