Falcon-S is a semantic web application focusing on soccer domain. 
At present, Falcon-S provides the following services:

- Basic search. Falcon-S provides basic service for searching objects (e.g., players, teams), semantic associations among objects (e.g. soccerPlayer playFor Team) and images about identified objects in the soccer domain. 
- Semantic search. Falcon-S provides an advanced service for searching objects by semantic query driven by domain-specific ontology. It provides a list of semantic queries in common use, and more importantly,  a graph-based user interface to let users customize their semantic queries based on existing ones or define new semantic queries from scratch. 
- Semantic exploring. Falcon-S provides a service for exploring objects in domain-specific ontology and knowledge base. Using Falcon-S, users can explore objects semantically associated by domain konwledge, and browse crawled images related with  identified objects.

Falcon-S is based on ontology and related technologies. An ontology and a knowledge base for the soccer domain are built by integrating the information from the official web site of FIFA, UEFA , existing work like [1], etc. It crawls the World Wide Web for images on soccer domain, analyses their context and indexes them on the individuals (e.g., players, teams) in the knowledge base. Keyword-based  queries are mapped to one or more such individuals, semantic associations among objects are extracted with an ontology-driven approach, and the related images are returned. Objects can be semantically explored through an ontological view. Most importantly, Falcon-S provides an ontology-driven approach to let users define their own semantic queries for searching domain-specific objects. This novel feature is implemented by using some advanced technologies, such as Ajax, SVG, etc. In addition, Falcon-S facilitates the low-level features of crawled images such as color histogram to improve the performance.

Try and enjoy Falcon-S!
