چکیده
The content is extracted by means of semantic relevancy. The semantic relevancies relate the content of videos based on a certain parameter. The parameter varies between system to system (implementation). The parameter will improve the performance of semantic relevancy and accuracy. This accuracy is obtained after various random experiments. Here a method called concept, sub concept graph method is used to implement the semantic relevancies. A graph algorithm is constructed to improve the relevancies between concepts. The ontology model is created based on the relationship between the vertices. At first relationship between the parent and child are calculated. Then based on all the relationships the diagrammatic representations are done. Based on hit rates the priority of web pages are done and based on the number of relationships the value for the vertices is noted.

Query Architecture Expansion in Web Using Fuzzy Multi Domain Ontology
Due to the increasing web, there are many challenges to establish a general framework for data mining and retrieving structured data from the Web. Creating an ontology is a step towards solving this problem. The ontology raises the main entity and the concept of any data in data mining. In this paper, we tried to propose a method for applying the "meaning" of the search system, But the problem ...
متن کاملInferring gene ontologies from pairwise similarity data
MOTIVATION While the manually curated Gene Ontology (GO) is widely used, inferring a GO directly from -omics data is a compelling new problem. Recognizing that ontologies are a directed acyclic graph (DAG) of terms and hierarchical relations, algorithms are needed that: analyze a full matrix of gene-gene pairwise similarities from -omics data; infer true hierarchical structure in these data rat...

Data mining, also known as knowledge discovery in database, is the process to discover unknown knowledge from a large amount of data. Text mining is to apply data mining techniques to extract knowledge from unstructured text. Text clustering is one of important techniques of text mining, which is the unsupervised classification of similar documents into different groups. The most important step...
متن کاملImproved ontology-based similarity calculations using a study-wise annotation model
A typical use case of ontologies is the calculation of similarity scores between items that are annotated with classes of the ontology. For example, in differential diagnostics and disease gene prioritization, the human phenotype ontology (HPO) is often used to compare a query phenotype profile against gold-standard phenotype profiles of diseases or genes. The latter have long been constructed ...
متن کاملAn Executive Approach Based On the Production of Fuzzy Ontology Using the Semantic Web Rule Language Method (SWRL)
Today, the need to deal with ambiguous information in semantic web languages is increasing. Ontology is an important part of the W3C standards for the semantic web, used to define a conceptual standard vocabulary for the exchange of data between systems, the provision of reusable databases, and the facilitation of collaboration across multiple systems. However, classical ontology is not enough ...
