Query evaluation techniques for large databases

by Goetz Graefe - ACM COMPUTING SURVEYS , 1993
"... Database management systems will continue to manage large data volumes. Thus, efficient algorithms for accessing and manipulating large sets and sequences will be required to provide acceptable performance. The advent of object-oriented and extensible database systems will not solve this problem. On ..."

Domain names - Implementation and Specification

by P. Mockapetris - RFC-883, USC/Information Sciences Institute , 1983

This RFC describes the details of the domain system and protocol, and assumes that the reader is familiar with the concepts discussed in a companion RFC, "Domain Names- Concepts and Facilities " [RFC-1034]. The domain system is a mixture of functions and data types which are an official pr ..."

Query expansion using lexical-semantic relations

by Ellen M. Voorhees - In Proceedings of the 17th Annual International ACM SIGIR Conference on Research and Development in Information Retrieval , 1994
"... Applications such as office automation, news filtering, help facilities in complex systems, and the like require the ability to retrieve documents from full-text databases where vocabulary problems can be particularly severe. Experiments performed on small collections with single-domain thesauri sug ..."

The design of Postgres

by Michael Stonebraker, Lawrence A. Rowe - In Proceedings of the SIGMOD Conference , 1986
"... This paper presents the preliminary design of a new database management system, called POSTGRES, that is the successor to the INGRES relational database system. The main design goals of the new system are to: 1) provide better support for complex objects, 2) provide user extendibility for data types ..."

types, operators and access methods, 3) provide facilities for active databases (i.e., alerters and triggers) and inferencing including forward- and backward-chaining, 4) simplify the DBMS code for crash recovery, 5) produce a design that can take advantage of optical disks, workstations composed

Querying the Internet with PIER

by Ryan Huebsch, Joseph M. Hellerstein, Nick Lanham, Boon Thau Loo, Scott Shenker, Ion Stoica - IN VLDB , 2003
"... The database research community prides itself on scalable technologies. Yet database systems traditionally do not excel on one important scalability dimension: the degree of distribution. This limitation has hampered the impact of database technologies on massively distributed systems like the Inter ..."

In this paper, we present the initial design of PIER, a massively distributed query engine based on overlay networks, which is intended to bring database query processing facilities to new, widely distributed environments. We motivate the need for massively distributed queries, and argue for a

Programs with Common Sense

by John McCarthy - Semantic Information Processing , 1968
"... This paper will discuss programs to manipulate in a suitable formal lan- guage (most likely a part of the predicate calculus) common instrumental statements. The basic program will draw immediate conclusions from a list of premises. These conclusions will be either declarative or imperative sentence ..."

sentences. When an imperative sentence is deduced the program takes a corresponding action. These actions may include printing sentences, moving sentences on lists. and reinitiating the basic deduction process on these lists. Facilities will be provided for communication with humans in the system via manual

The Object-Oriented Database System Manifesto

by Malcolm Atkinson, François Bancilhon, David DeWitt, Klaus Dittrich, David Maier, Stanley Zdonik , 1989
"... This paper attempts to define an object-oriented database system. It describes the main features and characteristics that a system must have to qualify as an objectoriented database system. We have separated these characteristics into three groups: ffl Mandatory, the ones the system must satisfy in ..."

Visual Information Retrieval

by Tat-Seng Chua Low, W. C. Low, Terence M. C. Sim - Journal of the Institiute of Image and Electronic Engineers of Japan , 1998
"... Introduction Present methods of retrieving images based on visual content largely center around the extraction of certain salient features of an image, such as color, texture, shape, and the computation of a similarity measure between two images. Such methods, while effective in particularly focuse ..."

-based retrieval systems, are lacking in content-based systems. Clearly, there is much more to be done in this area; we need to move towards a more intuitive, human-like query facility in order to allow laymen to use multimedia databases. In this article, we discuss the development of a multi-layered framework

From Structured Documents to Novel Query Facilities

by Christophides Abiteboul, V. Christophides, S. Abiteboul, S. Cluet, M. Scholl , 1994
"... Structured documents (e.g., SGML) can benefit a lot from database support and more specifically from object-oriented database (OODB) management systems. This paper describes a natural mapping from SGML documents into OODB's and a formal extension of two OODB query languages (one SQL-like and th ..."

Extracting structured data from web pages

by Arvind Arasu - In ACM SIGMOD , 2003
"... Many web sites contain a large collection of “structured” web pages. These pages encode data from an underlying structured source, and are typically generated dynamically. An example of such a collection is the set of book pages in Amazon. There are two important characteristics of such a collection ..."

Our goal is to automatically extract structured data from a collection of pages described above, without any human input like manually generated
