Information retrieval system

Gynecologic Oncology, 1977
Abstract An uncomplicated data retrieval system is described. The mechanics include a commercial unit, Acme Visible Records Electrofile. The unit has a keyboard and cards adapted for use in a gynecologic oncology service. This sytem enables the physician to record and retrieve information on a specific patient or group of patients quickly, without ...

Information Retrieval Models [PDF]

open access: yes, 2009
Many applications that handle information on the internet would be completely\ud inadequate without the support of information retrieval technology. How would\ud we find information on the world wide web if there were no web search engines?\ud How would ...

Bandit Algorithms in Information Retrieval

Foundations and Trends in Information Retrieval, 2019
Bandit algorithms, named after casino slot machines sometimes known as “one-armed bandits”, fall into a broad category of stochastic scheduling problems. In the setting with multiple arms, each arm generates a reward with a given probability. The gambler’

Information Retrieval: The Early Years

Foundations and Trends in Information Retrieval, 2019
Information retrieval, the science behind search engines, had its birth in the late 1950s. Its forbearers came from library science, mathematics and linguistics, with later input from computer science.

On fuzziness in information retrieval

International Journal of Man-Machine Studies, 1976
The IR systems are faced with a need to manage fuzziness and not merely to react to fuzziness. The indexing process is viewed as representing the set X of information items by fuzzy subsets ℱ(Y) of the descriptor set Y. A fuzzy assignment is modelled as a system (X,Y,f:X→ℱ(Y)) where f(x)(y) is the link between the information item x and the descriptor ...

An Information Retrieval Ontology for Information Retrieval Nanopublications

2014
Retrieval experiments produce plenty of data, like various experiment settings and experimental results, that are usually not all included in the published articles. Even if they are mentioned, they are not easily machine-readable. We propose the use of IR nanopublications to describe in a formal language such information.

Information retrieval by metabrowsing

Journal of the American Society for Information Science and Technology, 2004
AbstractThis article investigates a new, effective browsing approach called metabrowsing. It is an alternative for current information retrieval systems, which still face six prominent difficulties. We identify and classify the difficulties and show that the metabrowsing approach alleviates the difficulties associated with query formulation and missing

The Power of Noise: Redefining Retrieval for RAG Systems

Annual International ACM SIGIR Conference on Research and Development in Information Retrieval
Retrieval-Augmented Generation (RAG) has recently emerged as a method to extend beyond the pre-trained knowledge of Large Language Models by augmenting the original prompt with relevant passages or documents retrieved by an Information Retrieval (IR ...

Information calculus for information retrieval

Journal of the American Society for Information Science, 1996
Information is and always has been an elusive concept; nevertheless many philosophers, mathematicians, logicians and computer scientists have felt that it is fundamental. Many attempts have been made to come up with some sensible and intuitively acceptable definition of information; up to now, none of these have succeeded.

Information Retrieval I

1991
“Information retrieval” is a very loose term, so we must start by setting some limits to our subject. We are not concerned, for instance, with systems which respond to requests for specific facts, e.g. “What time is the next train to London?” Enquiry systems like that undeniably supply useful information, but they do not necessarily store and ...
