Title: The Innovations of Chin-Wan Chung

Introduction

Chin-Wan Chung is a prominent inventor based in Taejon, South Korea. He has made significant contributions to the field of technology, particularly in semantic search systems and data processing. With a total of 10 patents to his name, Chung's work has had a considerable impact on how information is retrieved and processed in various applications.

Latest Patents

Chung's latest patents include a semantic search system that utilizes a semantic ranking scheme. This system features an ontology analyzer that assesses ontology data related to a search target, determining weight values for each property. Additionally, it includes a semantic path extractor that identifies all semantic paths between resources and query keywords, assigning weight values based on a specific determination scheme. The relevant resource searcher traverses an instance graph of ontology to find resources with semantic relationships to the query keywords. Finally, a semantic relevance ranker selects the top-k results with the highest rank from the candidate results.

Another notable patent is an indexing system and method for nearest neighbor searches in high-dimensional data spaces. This invention approximates vectors representing objects in n-dimensional space using local polar coordinates on partitioned cells. It generates a set of candidate near neighbors based on these approximations, allowing for efficient querying of 'k' nearest neighbors. This method acts as a filter, significantly reducing the number of actual data vectors that need to be considered in response to a query.
