The Geographic Knowledge Base Project |
||||||||||||||||
Brief Description Knowledge bases in the form of knowledge graphs have wide applications in search engines (such as Google¨s Knowledge Graph), virtual assistants and question answering systems (such as Siri), recommender systems, and natural language generation.
This project aims at building, Geographic Knowledge Base (GKB), a knowledge base in a specific domain, geography, with much larger coverage of geographic entities and much richer information than existing generic knowledge bases have. It is a foundational technology for the next generation navigation systems as shown by the example below.
When you are at the above street location, compare the following two navigation systems:
A GKB is essential for providing the instructions like "turn right at the 3 story red and yellow building" in the next generation navigation systems.
In a GKB, we are interested in microscopic geographic entities, which are defined as those geographic entities with the finest level of address such as an apartment building, a house, a stadium, a bridge, a park, etc. A microscopic geographic entity corresponds to a place in Google Maps. The rich information we aim to get include visual features (color, height, materials, architecture style, etc), textual description (functionality, history, etc), and conceptual information such as the importance of a geographic entity.
