User Navigation in the IRS Conceptual Structure through a Semantic Association Function

M. Agosti, P. G. Marchetti
1992 Computer journal  
This paper addresses the methodological aspects of designing a semantic association function in a hypertext information retrieval environment and model.  ...  Through this function a part of an associative information retrieval model is designed and implemented.  ...  The present work has been developed in the framework of a joint research activity carried on by the European Space Agency and the University of Padova.  ...

Design and implementation of a tool for the automatic construction of hypertexts for information retrieval

Maristella Agosti, Fabio Crestani, Massimo Melucci
1996 Information Processing & Management  
The structure of the hypertext re ects a three level conceptual model that has proved to be quite e ective for Information Retrieval.  ...  Through the use of an authoring methodology employing a set of well known Information Retrieval techniques, TACHIR automatically builds up a hypertext from a document collection.  ...  Acknowledgments The authors would like to thank the reviewers for the useful comments on the earlier version of the paper.  ...

Querying office systems about document roles

A. Celentano, M. G. Fugini, S. Pozzi
1991 Proceedings of the 14th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '91  
The paper focuses on the query language that allows the user to pose queries involving the analysis of both the semantic network where procedures, office agents, and events of the office context are represented  ...  The system relies on a knowledge representation model for document and document roles developed in previous phases of the research.  ...  QUS breaks up a query into the components involving the semantic network, the conceptual structure and the text analysis.  ...

Approaching Wordnets through a Structural Point of View [chapter]

Dimitris Avramidis, Maria Kyriakopoulou, Manolis Tzagarakis, Sofia Stamou, Dimitris Christodoulakis
2003 Lecture Notes in Computer Science  
Moreover, wordnets form the most representative type of semantic networks in the field of Natural Language Processing and semantics in particular.  ...  The analogy of a semantic network to hypertext has long been recognized, and semantic networks have been considered as a logical model of hypertext -especially for those hypertexts with typed nodes and  ...  On the other hand, semantic networks form a highly structured linguistic resource enabling a flexible navigation through the lexical items of a language.  ...

Knowledge Navigation in Networked Digital Libraries [chapter]

Mike P. Papazoglou, Jeroen Hoppenbrouwers
1999 Lecture Notes in Computer Science  
Formulating precise and e ective queries in document retrieval systems requires the users to predict which terms appear in documents relevant to their information needs.  ...  In this paper we consider the concept of knowledge navigation for federated digital libraries and explain how it can provide the kind of intermediary expert prompting required to enable purposeful searching  ...  Therefore, the topic structure assists the user to nd where a speci c term that the user has requested lies in its conceptual space and allows users to pick other term descriptions semantically related  ...

Embedding information retrieval in adaptive hypermedia: IR meets AHA!

Lora Aroyo, Paul De Bra, Geert-Jan Houben, Richard Vdovjak
2004 New Review of Hypermedia and Multimedia  
We take a look at this issue in the context of an abstract reference model (AHAM), and in the context of a concrete implementation framework (AHA!).  ...  Certain applications ask for an extension of the contents considered, with data obtained through information retrieval.  ...  of the semantics associated to the different sources [25] .  ...

Knowledge-based document retrieval in office environments: the Kabiria system

Augusto Celentano, Maria Grazia Fugini, Silvano Pozzi
1995 ACM Transactions on Information Systems  
To fulfill the requirements of such a sophisticated retrieval, we propose a document retrieval model and system based on the representation of knowledge describing the semantic contents of documents, the  ...  way in which the documents are managed by procedures and by people in the office, and the application domain where the office operates.  ...  It attempts to find corresponding nodes in the tree structures, by navigating through them in a base.  ...

Maristella Agosti, Fabio Crestani

Modeling Legal Documents as Typed Linked Data for Relational Querying

Nada Mimouni
2013 International Conference on Legal Knowledge and Information Systems  
Modeling the collection of documents in such complex domains requires taking into account the semantic content of the documents as well as their relational structure since documents are usually related  ...  Not only is legal knowledge usually expressed in linguistically complex forms, but it is also structurally sophisticated (e.g pieces of legislation applicable to a case, version in force of a legal document  ...  Semantic and relational search is handled by both general search engines and specialized legal IR systems in different ways: classic IR on semantic content then navigation with hyperlinks, boolean IR on  ...
