Purpose: Data integration and applications across knowledge graphs (KGs) rely heavily on the discovery of links between resources within these KGs. Geospatial link algorithms have to deal with millions point sets containing billions points. Methodology: To speed up geospatial links, we propose COBALT. COBALT combines content measures R-tree indexing. The are based area, diagonal distance minimu...

Today’s offer of audio content exceeds the human capability of manually searching datasets with hundreds of songs, demanding automated tools capable of handling music recommendation when faced with large-scale collections. In this work, we address the playlist generation and song discovery tasks with large-scale datasets. It is possible to quickly obtain playlists and explore collections with e...

The dramatically explosion of data and the growing number of different data sources are exposing researchers to a new challenge how to acquire, maintain and share knowledge from large databases in the context of rapidly applied and evolving research. This paper describes a research of an ontological approach for leveraging the semantic content of ontologies to improve knowledge discovery in dat...

The advent of social tagging systems has enabled a new community-based view of the Web in which objects like images, videos, and Web pages are annotated by thousands of users. Understanding the emergent semantics inherent in the socially-generated collection of annotations has important research implications for information discovery and knowledge sharing. To this end, we propose a novel probab...

This study investigated discovery learning pedagogy and its effects on students' achievement and attitudes toward instruction in a lower-division biology course, entitled Structure and Function of Organisms. Instruction was primarily lecture-based but included four discovery learning activities. Results indicate that students had greater achievement on content learned through discovery methods ...

this manuscript is a review of a number of ethnobotany and ethnopharmacology texts and papers in order to arrive at current understanding and scope of ethnobotany and ethnopharmacology. it includes either a brief definition of both fields and presenting some examples on them. also it has a glimpse on the geographical coverage of research works throughout the world, important issue of property r...

malaria is currently one of the most important causes of mortality in developing countries. high resistance to available antimalarial drugs has been reported frequently, thus it is crucial to focus on the discovery of new antimalarial drugs. artemisinin, an effective antimalarial medication, is isolated from various artemisia species. to identify the artemisia species producing high quantity of...
