The workshop will discuss semantics of logic programs over general semirings: constraints over semirings, query complexity with semiring semantics, termination conditions of logic programs over semirings. The connection between semirings and logic is a relatively new development in database theory (since 2007), and this area has high potential for major innovation. Some of the problems discussed at the workshop will be inspired by systems, others will be purely theoretical in nature, such as the quest for finding appropriate extensions of Pebble Games to semiring semantics.
