Towards Water Environmental Ontology Construction and Data Retrieval

Towards an optimal ontology construction

A subject of ontology, its usage, building and evaluation has been becoming one of the most popular research topics for the last ten years. Such a strong interest to this issue can be explained by great expectations that scientists relate to a widespread ontology’s usage. Following by Uschold [46] we can emphasize 3 main ontology’s purposes: 1. Intelligent communication between different domain...

Public Transport Ontology for Passenger Information Retrieval

Passenger information aims at improving the user-friendliness of public transport systems while influencing passenger route choices to satisfy transit user’s travel requirements. The integration of transit information from multiple agencies is a major challenge in implementation of multi-modal passenger information systems. The problem of information sharing is further compounded by the multi-l...

Ontology Construction from Phenotype Data

Towards Adaptive Ontology-Based Image Retrieval

Since the use of large image databases gains in importance nowadays, efficient querying and browsing through image repositories becomes increasingly essential. Compared to text retrieval techniques there are even more problems with image retrieval. Particularly, the semantic gap between low-level visual features of images and high-level human perception of inferred semantic contents decreases t...

Information Retrieval Support for Ontology Construction and Use

Information retrieval can contribute towards the construction of ontologies and the effective usage of ontologies. We use collocation-based keyword extraction to suggest new concepts, and study the generation of hyperlinks to automate the population of ontologies with instances. We evaluate our methods within the setting of digital library project, using information retrieval evaluation methodo...
