“…With the ontology navigation interface the users can view ontology individuals and their properties and browse properties via hyperlinks. Browsing the ontology is essential for the user in order to explore the available information and it also helps non-expert users to refine their search requirements when they start with no specific requirement in mind (Ram & Shankaranarayanan, 1999). The hierarchical organization of the different concepts and individuals of the ontology is graphically represented as a dynamic tree.…”

This paper presents a conceptual and computational framework for supporting the development of knowledge management systems based on ontology design and implementation. This framework supports enterprises involved in the design and manufacturing of complex mechanical products: in particular, we focus our attention on a network of small/medium Italian enterprises that collaborates in the production of a supermotard bike calledTerra Modena 198. Starting from some theoretical considerations about the role of ontologies in engineering design, this paper reflects on the difficulties that arise when knowledge is distributed, and misunderstanding and communication problems among partners could easily lead to errors in the final product.

“…In the area of information systems, the concept of information navigation has been associated with visualization of retrieval results [11] [17] and with information access in an information space [10] [5]. This work uses a topic-based cluster as a semantic structure of connected news that can be used in a navigation process.…”

Abstract. The growing amount of online news posted on the WWW demands new algorithms that support topic detection, search, and navigation of news documents. This work presents an algorithm for topic detection that considers the temporal evolution of news and the structure of web documents. Then, it uses the results of the topic detection algorithm for searching and navigating in an online news source. An experimental evaluation with a collection of online news in Spanish indicates the advantages of incorporating the temporal aspect and structure of documents in the topic detection of news. In addition, topic-based clusters are well suited for guiding the search and navigation of news.

“…In this context, the navigation is carried out over a semantic structure, called information space, that connects different sources [13]. This work concerns the second perspective of a navigation process.…”

Abstract. Querying heterogeneous spatial databases involves not only characterizing and comparing the information content of several databases, but also navigating or accessing the data sets with the query answer. This work proposes a formalism that relates the information content of data sets by three basic types of correspondence relations: data equivalence, difference of data omission, and difference of data commission. These correspondence relations define the information space over which a navigation process is carried out. Based on a complete or an incomplete information space, this work proposes strategies that optimize the retrieval process of information coming from different databases. The results of this study show the advantages of defining the information space to select and access databases. In particular, strategies that estimate the information contribution of data sets based on correspondence relations outperform a strategy that considers a random list or a list of data sets sorted by size.
