Petri-net-based hypertext: document structure with browsing semantics

P. David Stotts, Richard Furuta
1989 ACM Transactions on Information Systems  
The model is based on Petri nets, and is a generalization of existing directed graph-based forms of hypertext.  ...  The Petri net basis permits more powerful specification of what is to be displayed when a hypertext is browsed and permits application of previously developed Petri net analysis techniques to verify properties  ...  To summarize, a marked hypertext combines graphical structure with Petri net execution semantics to encapsulate all possible paths that a reader may follow through a document.  ...

WWW Workflows Based on Petri Nets [chapter]

Konstantin Knorr
2001 Contemporary Trends in Systems Development  
This paper describes a model for workflows based on Petri nets which are well suited to represent discrete dynamic models and provide a solid formal foundation.  ...  WoPIx is based on pure Petri nets, is light weighted, robust, and platform independent. The remainder of the paper has the following structure: Section 2 concentrates on other WWW based WfMSs.  ...  PETRI NETS Petri nets originated with Carl Adam Petri (Petri, 1962) . Nowadays, their theory and application is a vast research area with many publications.  ...

Context-Aware Digital Documents Described In a High-Level Petri Net-Based Hypermedia System [chapter]

Jin-Cheon Na, Richard Furuta
2004 Lecture Notes in Computer Science

Using statecharts to model hypertext

Yi Zheng, Man-Chi Pong
1992 Proceedings of the ACM conference on Hypertext - ECHT '92  
The statechart model is compared with other models for hypertext based on simple node-and-link graph, first-order logic formulae, hypergraph, and petri net.  ...  These examples illustrate that statecharts can be used to abstract the structure from the content of hypertext, and to model the structure and the browsing semantics of hypertext clearly and vividly.  ...  Acknowledgement Part of this work was done while the first author was with the University of Kent at Canterbury, U. K., and she would like to thank the guidance of Professor Peter J. Brown.  ...

Adding browsing semantics to the hypertext model

1988 Proceedings of the ACM conference on Document processing systems - DOCPROCS '88  
The Petri net base also permits more powerful specification of what is to be displayed when the hypertext is browsed.  ...  The model is based on Petri nets, and is a generalization of existing directed graph based models.  ...  To summarize, a hypertext combines graphical structure with Petri net execution semantics to encapsulate all possible valid interactions that a reader may have with the document.  ...

Models for hypertext

Mark F. Frisse, Steve B. Cousins
1992 Journal of the American Society for Information Science  
Interfaces exhibiting the "power of linking" can be found in software ranging from document preparation programs to operating systems, providing users with many new ap proaches to individual and group  ...  Features characteristic of hypertext are no longer the providence of specialized hypertext systems.  ...  First, the model is based on Petri nets; places represent possible actions such as display of a component. Transitions between places occur only when places are in a prespecified state.  ...

Applying programmable browsing semantics within the context of the World-Wide Web

Richard Furuta, Jin-Cheon Na
2002 Proceedings of the thirteenth ACM conference on Hypertext and hypermedia - HYPERTEXT '02  
We discuss application of caT (context-aware Trellis), which extends the Trellis Petri-net-based model of hypertext, towards specification of Web-browsable hypertexts that respond to factors that occur  ...  In addition to characteristics such as a reader's role (e.g., student, teacher, administrator, or parent) and the reader's browsing history, we also include factors that may not have been incorporated  ...  Trellis maps the Petri net to hypertext semantics, thereby defining not only the hypertext's nodes and links, but also its browsing semantics-where browsing semantics means the document behaviors (e.g.  ...

Structured hypertext with domain semantics

Weigang Wang, Roy Rada
1998 ACM Transactions on Information Systems  
One important facet of current hypertext research involves using knowledge-based techniques to develop and maintain document structures. A semantic net is one such technique.  ...  This work tackles the above problems by integrating logical structure and domain semantics into a semantic net. A semantic-net-based structured-hypertext model has been formalized.  ...  The automaton-based approach emphasizes inherent document structure with browsing semantics.  ...

The extensions incorporated into hypercharts are based on the major characteristics of some Petri net based multimedia models, and make it an alternative to such models for multimedia and hypermedia specification  ...  XHMBS uses a novel formalism called hypercharts as its underlying model for specifying the navigational structure, browsing semantics and synchronization requirements of a hyperdocument.  ...  DISCUSSION The Trellis model [17] was originally developed for hypertext applications, and uses Petri nets not only to represent the structure but also to specify the browsing semantics of a hypertext  ...
