This paper proposes an approach to automated ontology alignment and domain ontology extraction from two knowledge bases. First, WordNet and HowNet knowledge bases are aligned to construct a bilingual universal ontology based on the co-occurrence of the words in a parallel corpus. The bilingual universal ontology has the merit that it contains more structural and semantic information coverage fr...

What are specific relations between Web-semantic and ontology (Uschold, 2005)? What is an ontology of a domain? What are the relations between texts relative to a domain and an ontology of this domain? How to build an ontology from texts (Aussenac-Gilles et al., 2005)? In our approach of these questions, we consider that there are different levels of ontologies: (i) ontology of a domain; (ii) o...

When considering an existing ontology for reuse to annotate new data, one needs to check if the ontology contains classes and properties suitable for describing the data. Visualizing the ontology itself in some of the available tools, to support such a decision, is an obvious option. We propose that ontology usage visualization, a slight variant of dataset schema visualization, might however be...

We describe the Data Mining OPtimization Ontology (DMOP), which was developed to support informed decision-making at various choice points of the knowledge discovery (KD) process. DMOP contains in-depth descriptions of DM tasks, data, algorithms, hypotheses, and workflows. Its development raised a number of non-trivial modeling problems, the solution to which demanded maximal exploitation of OW...

Video data is being collected at alarming rates and yet there exists no comprehensive forensic toolset that enables the analyst to quickly examine video in the context of the massive collections. This research builds a System that studies video at a semantic level by means of a joint solution to semantic entity extraction, entity-entity relationship extraction, and dynamic event recognition. Th...

The biological ontology applied to all organisms is useful to exchange genome informatics and to compare them. On one hand, biological domain ontology for specific organism is necessary to provide controlled common vocabulary for researchers interested in the field. In the biological domain ontology, gene, gene product, and biological process should be reasonably connected for covering knowledg...

With the dramatic increase in the amount of content available in digital forms gives rise to a problem to manage this online textual data. As a result, it has become a necessary to classify large texts (documents) into specific classes. And Text Classification is a text mining technique which is used to classify the text documents into predefined classes. Most text classification techniques wor...

The enormous growth of the World Wide Web in recent years has made it necessary to perform resource discovery efficiently. For a crawler it is not an simple task to download the domain specific web pages. This unfocused approach often shows undesired results. Therefore, several new ideas have been proposed, among them a key technique is focused crawling which is able to crawl particular topical...
