Proceedings of the Third International Workshop on Keyword Search on Structured Data

Information search is an indispensable component of our lives. Web search engines are widely used for searching textual documents, images, and video. However, there are also vast collections of structured and semi-structured data both on the Web and in enterprises, such as relational databases, XML data, etc. Traditionally, to access these resources, a user must learn structured or semi-structured query languages, and must be able to access data schemas, which are most likely heterogeneous, complex, and fast-evolving. To relieve web and scientific users from the learning curve and enable them to easily access structured and semi-structured data, there is a growing research interest to support keyword search on these data sources. The third International Workshop on Keyword Search on Structured Data (KEYS 2012) is held in Scottsdale, Arizona, USA on 20th May, 2012, in conjunction with SIGMOD 2012 conference, and aims to encourage researchers from both academia and industry communities to discuss the opportunities and challenges in keyword search on (semi-)structured data, and to present the key issues and novel techniques in this area. In response to the call for papers, KEYS 2012 has attracted highly diversified submissions, coming from USA, China, UK, Greece, Singapore, Mexico and Japan, resulting in an international final program. All submissions were peer reviewed by three program committee members. The program committee selected 8 full research papers for inclusion in the proceeding. The accepted papers covered a wide range of research topics and novel applications on keyword search on structured data.
