The Building Information Model (BIM) has become a key tool to achieve communication during the whole building life-cycle. Open standards, such as the Industry Foundation Classes (IFC), have contributed to expand its adoption, but they have limited capabilities for cross-domain information integration and query. To address these challenges, the Linked Building Data initiative promotes the use of...

Abstract Governing human interaction in the maritime space implicitly rests on ascription of value to this space. Environmental ethics helps disentangle many concepts that may come conflict. As a particularly contested concept, ecocentrism assigns not just at atomistic level, but also holistic one. It has, however, been subject criticism, thus challenging validity recent approaches ocean manage...

Fuzzy Description Logics have been widely studied as a formalism for representing and reasoning withvague knowledge. One of the most basic reasoning tasks in (fuzzy) Description Logics is to decide whetheran ontology representing a knowledge domain is consistent. Surprisingly, not much is known about thecomplexity of this problem for semantics based on complete De Morgan lattices. T...

Currently, most tourists use the Internet to retrieve information for supporting their decision in selecting the tourist places that conform to their preferences. The most common method is the decision based on reviews of experienced tourists. However, tourists must read enormous reviews in order to select their preferred tourist places. This article presents an analysis module for online trave...

Classical ontologies are not suitable to represent vague pieces of information, which has lead to the birth of Fuzzy Description Logics as an appropriate formalism to represent this type of knowledge. Different families of fuzzy operators lead to Fuzzy Description Logics with different properties. This paper studies Fuzzy Description Logics under a semantics given by the Gödel family of fuzzy o...

Natural languages all over the world are contextbased. There is inherent vagueness present in the common usage of language, but it is easily understood by people because they can decipher the context of the communication easily. Emails are an extension of face-to-face communication and many elements of ambiguity are present in the language used within the body of emails. In a computer based app...

Association rule mining is an active data mining research area. Recent years have witnessed many efforts on discovering fuzzy associations. The key strength of fuzzy association rule mining is its completeness. This strength, however, comes with a major drawback to handle large datasets. It often produces a huge number of candidate itemsets. The huge number of candidate itemsets makes it ineffe...

Query refinement can help users find information on the Internet more effectively. This feature has been implemented in a Personalized Abstract Search Services (PASS) system, a Web-based, domain-specific search engine for searching abstracts of research papers. The system uses a fuzzy ontology of term associations to support the feature. The ontology is automatically built in two stages using i...

In environmental databases there is a plethora of data, described in different terminologies, stored in different data structures and referring to distinct time periods and locations. Thus it is difficult for non-experts to find the data they are looking for. Adding an ontology-layer, which provides semantic enhancement, provides the underlying data structure for an open and intuitive search in...
