Query Processing and Optimization for Pictorial Query Trees

1999
Methods for processingo f pictorial queries specified by pictorial query trees are presented. Leaves of a pictorial query tree correspond to individual pictorial queries while internal nodes correspond to logical operations on them. Algorithms for processing individual pictorial queries and for parsing and computingt he overall result of a pictorial ...

Query Processing in Relationlog

1999
Relationlog is a persistent deductive database system that supports effective storage, effcient access and inference of large amounts of data with complex structures. In this paper, we describe query processing in the Relationlog system. In particular, we illustrate the extended semi-naive and magic-set techniques used in Relationlog.

Aero: Adaptive Query Processing of ML Queries

Proceedings of the ACM on Management of Data
Query optimization is critical in relational database management systems (DBMSs) for ensuring efficient query processing. The query optimizer relies on precise selectivity and cost estimates to generate optimal query plans for execution. However, this static query optimization approach falls short for DBMSs handling machine learning (ML) queries.

Cognitive Processes in Query Generation

2011
Known-item search is the search for a specific document that is known to exist. This task is particularly important in Personal Information Management (PIM), where it is the most common search activity. A major obstacle to research in search technologies for PIM is the lack of publicly accessible test corpora.

Robust Query Processing: A Survey

Foundations and Trends in Databases
The primordial function of a database system is to efficiently compute correct answers to user queries. Therefore, robust query processing (RQP), where strong numerical guarantees are provided on query performance, has been a long-standing core objective in the design of industrial-strength database engines. Unfortunately, however, RQP has proved to be
