Querying structured documents with hypertext links using OODBMS

V. Christophides, A. Rizk
1994 Proceedings of the 1994 ACM European conference on Hypermedia technology - ECHT '94  
Querying in hypertext has been a requirement since [19] and has already been elaborated in many hypertext systems [11,7,4,21], but has not yet been used for hypertext systems superimposed on an underlying  ...  Hierarchical logical structure and hypertext links are complementary and can be combined to build more powerful document management systems [28, 25,24, 13].  ...  Vercoustre for helpful comments.  ...

A probabilistic approach to navigation in Hypertext

Mark Levene, George Loizou
1999 Information Sciences  
We de ned a Hypertext Query Language, HQL, over Hypertext databases and showed that in general the navigation problem, i.e. the problem of nding a trail that satis es a HQL query (technically known as  ...  The notion of a trail, which is a path in the database graph describing some logical association amongst the pages in the trail, is central to our model.  ...  In Section 5 we de ne a probabilistic query language for Hypertext and investigate the complexity o f m o d e l c hecking in this query language.  ...

Hyperdocuments as automata

P. David Stotts, Richard Furuta, J. Cyrano Ruiz
1992 Proceedings of the ACM conference on Hypertext - ECHT '92  
In many hypertext systems, meaningfully traversing a document depends on capabilities, features, and navigational aids that are part of the browser implementation.  ...  For example, if a reader browses to a node that has no out links, then backing up, or "warping" to the table of contents can allow the browsing session to continue.  ...  queries expressible in the new language."  ...

COMFRESH: A common framework for expert systems and hypertext

F.A Kokkoras, I.P Vlahavas
1995 Information Processing & Management  
In this paper we propose the "COMFRESH", a common framework for expert systems and hypertext.  ...  COMFRESH can be used as a knowledge based hypertext (intelligent hypertext) or as an expert system with hypertext capabilities.  ...  Logic Petri net model provides a bridge between the informal semantic nets of hypertext and the formal logic systems.  ...

A DSL based on CSS for hypertext adaptation

Alejandro Montes García, Paul De Bra, George H.L. Fletcher, Mykola Pechenizkiy
2014 Proceedings of the 25th ACM conference on Hypertext and social media - HT '14  
In order to ease the development of such systems, we propose a language based on CSS to express personalization in web systems that captures current adaptation techniques.  ...  Personalization offered by Adaptive Hypermedia and Recommender Systems is effective for tackling the information overload problem.  ...  To connect queries with a logical OR, the user/context queries have to be separated by commas. A logical AND is achieved by nesting them.  ...

Languages and Tools to Specify Hypertext Views on Databases [chapter]

G. Falquet, J. Guyot, L. Nerima
1999 Lecture Notes in Computer Science  
We present a declarative language for the construction of hypertext views on databases.  ...  The language is based on an object-oriented data model and a simple hypertext model with reference and inclusion links.  ...  The MetaLAZY tool is an implementation of the hypertext view language for a semantic data model.  ...

Combining structure search and content search for the World-Wide Web

Hermann Kaindl, Stefan Kramer, Luis Miguel Afonso
1998 Proceedings of the ninth ACM conference on Hypertext and hypermedia : links, objects, time and space---structure in hypermedia systems links, objects, time and space---structure in hypermedia systems - HYPERTEXT '98  
As a consequence, we propose this approach for searching the World-Wide Web.  ...  A prerequisite of full-fledged structure search would be that links are firstclass objects. This is obviously not the case for the representation of links in the WWW.  ...  ACKNOWLEDGMENTS The European Leonardo program supported the visit of the third author to Austria, where he worked for Siemens in an internship.  ...

Style sheet support for hypermedia documents

Jacco van Ossenbruggen, Lynda Hardman, Lloyd Rutledge, Anton Eliëns
1997 Proceedings of the eighth ACM conference on Hypertext - HYPERTEXT '97  
A style sheet defines a mapping from a source document to a presentation for it.  ...  Hypermedia documents are most often created with a particular presentation environment in mind. This requires the authoring of one document per presentation platform.  ...  A hypermedia style sheet language must combine a powerful query language with a sufficiently rich model of the presentation environment.  ...

Schema-based authoring and querying of large hypertexts

Bernd Amann, Michel Scholl, Antoine Rizk
1995 International Journal of Human-Computer Studies  
In this paper, we show how hypertext schemas and query languages can be utilized for designing hypertext authoring and browsing environments for large hypertexts.  ...  Systems such as Multicard/O¡ and MORE have moreover exploited conceptual schemas for querying the resulting hyperdocuments in a more structured way.  ...  A graphical query interface under development is a first step toward a complete visual query language and tool for query based navigation through hypertexts.  ...

Querying typed hypertexts in Multicard/O2

Bernd Amann, Michel Scholl, Antoine Rizk
1994 Proceedings of the 1994 ACM European conference on Hypermedia technology - ECHT '94  
In this paper, we will show how query languages could be further exploited for designing sophisticated general query-based navigation mechanisms.  ...  A general solution is to extend hypertext systems to cater for semantics of application domains. This requires new hypertext models providing strongly typed documents and links.  ...  O2SQL is a high-level query language for querying O2 databases.  ...

A Semantic Model for Hypertext Data Caching [chapter]

Kai Cheng, Yahiko Kambayashi
2002 Lecture Notes in Computer Science  
In this paper, we propose a semantic model to capture the semantic locality in hypertext access for client-side caching.  ...  To characterize hypertext data from the perspective of clients, we define a semantic region as a cluster of semantically related logical documents.  ...  Acknowledgments The authors would like to thank Mukesh Mohania and Yanchun Zhang for many interesting discussions.  ...

Navigation in Hypertext Is Easy Only Sometimes

Visual Querying for the Semantic Web [chapter]

Sacha Berger, François Bry, Christoph Wieser
2004 Lecture Notes in Computer Science  
Last but not least, a visual query language conceived as an Hypertext application is especially accessible for Web and Semantic Web application developers.  ...  Third, visXcerpt has been conceived as a mere Hypertext rendering of a textual query language. This approach to developing a visual language is fully new. It has several advantages.  ...  The visXcerpt prototype demonstrated is implemented using only well-established techniques like CSS, ECMAScript, and XSL and, of course, the run time system of the textual query language (Xcerpt [SF04]  ...
