Our findings lend epidemiologic support to the concept that nutrition rich in spermidine is linked to increased survival in humans. This trial was registered at www.clinicaltrials.gov as NCT03378843.
3D Virtual Worlds have the potential to expand the knowledge of a foreign culture by presenting the information in a visual context. In this paper we describe the design and evaluation of ICURA, a Serious Game that provides an opportunity to learn more about Japanese culture and etiquette. ICURA incorporates different game design and learning principles to effectively communicate knowledge. The main goal is to combine aspects of learning and fun in an immersive 3D Environment to make the communication of knowledge an entertaining experience. We evaluated the game through a user study with 20 participants. The comparison of pre-and post-test results highlights the positive learning effect of ICURA.
We present the ICARUS Coreference Explorer, an interactive tool to browse and search coreference-annotated data. It can display coreference annotations as a tree, as an entity grid, or in a standard textbased display mode, and lets the user switch freely between the different modes. The tool can compare two different annotations on the same document, allowing system developers to evaluate errors in automatic system predictions. It features a flexible search engine, which enables the user to graphically construct search queries over sets of documents annotated with coreference.
In this paper, we identify the problems of current semantic and hybrid search systems, which seek to bridge structure and unstructured data, and propose solutions. We introduce a novel input mechanism for hybrid semantic search that combines the clean and concise input mechanisms of keyword-based search engines with the expressiveness of the input mechanisms provided by semantic search engines. This interactive input mechanism can be used to formulate ontology-aware search queries without prior knowledge of the ontology. Furthermore, we propose a system architecture for automatically fetching relevant unstructured data, complementing structured data stored in a Knowledge Base, to create a combined index. This combined index can be used to conduct hybrid semantic searches which leverage information from structured and unstructured sources. We present the reference implementation Hybrid Semantic Search System (H S 3), which uses the combined index to put hybrid semantic search into practice and implements the interactive ontology-enhanced keyword-based input mechanism. For demonstration purpose, we apply H S 3 to the tourism domain. We present performance test results and the results of a user evaluation. Finally, we provide instructions on how to apply H S 3 to arbitrary domains.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
