duplicated/missing entries, and it is a natural practice to clean the data
first before executing the query. However, the same query might return
different answers on different cleaned versions of the dataset. It is then
helpful to compute the consistent answers: the query answers that will always
be returned, regardless of how the dirty data is cleaned. In this talk, we
first introduce the connection between first-order logic and query languages
on databases, and then discuss the problem of Consistent Query Answering
(CQA): How to compute consistent answers on dirty data? Finally, we show
when the CQA problem can be solved using first-order logic for path queries.

The Graduate Logic Seminar is an informal space where graduate students and professors present topics related to logic which are not necessarily original or completed work. This is a space focused principally on practicing presentation skills or learning materials that are not usually presented in a class.

  • When: Tuesdays 4-5 PM
  • Where: Van Vleck 901
  • Organizers: Jun Le Goh

The talk schedule is arranged at the beginning of each semester. If you would like to participate, please contact one of the organizers.

Title: First-order logic, database and consistent query answering

Abstract: Databases are a crucial component of many (if not all) modern applications. In reality, the data stored are often dirty and contain duplicated/missing entries, and it is a natural practice to clean the data first before executing the query. However, the same query might return different answers on different cleaned versions of the dataset. It is then helpful to compute the consistent answers: the query answers that will always be returned, regardless of how the dirty data is cleaned. In this talk, we first introduce the connection between first-order logic and query languages on databases, and then discuss the problem of Consistent Query Answering (CQA): How to compute consistent answers on dirty data? Finally, we show when the CQA problem can be solved using first-order logic for path queries.
