Most current definitional question answering systems apply one-size-fits-all lexicosyntactic patterns to identify definitions. By analyzing a large set of online definitions, this study shows that the semantic types of definienda constrain both lexical semantics and lexicosyntactic patterns of the definientia. For example, “heart” has the semantic type [Body Part, Organ, or Organ Component] and...

Conceptual modeling in Business Process Management (BPM) is one of the core research areas of Information Systems (IS). A variety of different strategies for modeling support and model analysis exists such as syntax-based auto-completion features, recommendation techniques, correctness and compliance checking, abstraction and matching, semantic and domain patterns, or AI-based planning approach...

While syntactic regularities or syntactic patterns, which are sets of axioms in an OWL ontology with a repeating structure, can help to understand the authoring style of an ontology and identify regular design, they can lack uniformity as they are sensitive to syntactic variations in asserted axioms. Cluster analysis of the implicit information provided by an OWL DL reasoner can contribute to t...

Trajectory pattern mining is becoming increasingly popular because of the development of ubiquitous computing technology. Trajectory data contain abundant semantic and geographic information that reflects people’s movement patterns, i.e., who is performing a certain type of activity when and where. However, the variety and complexity of people’s movement activity and the large size of trajector...

OBJECTIVE To improve semantic interoperability of electronic health records (EHRs) by ontology-based mediation across syntactically heterogeneous representations of the same or similar clinical information. MATERIALS AND METHODS Our approach is based on a semantic layer that consists of: (1) a set of ontologies supported by (2) a set of semantic patterns. The first aspect of the semantic laye...

We illustrate the effectiveness of medium-sized carefully tagged bilingual core corpus, that is, “semantic typology patterns” in our term together with some examples to give concrete evidence of its usefulness. The most important characteristic of these semantic typology patterns is the bridging mechanism between two languages which is based on sequences syntactic codes and semantic codes. This...

Web Usage Mining (WUM) is the application of data mining techniques over web server logs in order to extract navigation usage patterns. Semantic Web Usage Mining aims at combining the Semantic Web and WUM. The main goal of the Semantic WUM is to improve the process and the results of WUM by exploiting the new semantic structure in the Web. Pattern analysis is a critical phase in WUM, for two ma...

Interoperability is one of the major design objectives when building applications for B2B and Semantic Web applications. In this paper, we present a methodology for engineering semantic knowledge such that these semantic structures are easier reusable when switching between several representation languages. For this purpose, we reconsider the commonalities of representation languages and their ...
