Information Hierarchy
Data
The raw material of information
Information
Data organized and presented in a particular manner
Knowledge
“Justified true belief”
Information that can be acted upon
Wisdom
Distilled and integrated knowledge
Demonstrative of high-level “understanding”
Retrieval?
“Fetch something” that’s been stored
Recover a stored state of knowledge
Search through stored messages to find some messages relevant to the task at hand
TYPES OF INFORMATION RETRIEVAL
Information retrieval from digital libraries are classified into 3types
From the search for information about a well-defined and known object(s)
From the search for information about an object that cannot be fully described, but will be recognized on sight
From the accidental, incidental, or serendipitous discovery of an object
SERPENDITIOUS Ir
serendipitous approach, is a type of information seeking that is not traditionally examined in information retrieval research
It is retrieval of information accidental, incidental, or serendipitous discovery of an object
Serendipitous information retrieval occurs when a user with no a priori intentions interacts with a node of information and acquires useful information.
Inducing Serendipity
Serendipity means a "happy accident" or "pleasant surprise"; specifically, the accident of finding something good or useful without looking for it
Two purposes: one with a specified goal and one with no pre-defined goal. The first was operationalized as ‘find the answer to a set of questions', while the second was 'read/browse the newspaper for the next 20 minutes‘
The purpose operationalized as ‘no goal’ was devised to simulate a type of browsing.
Facilitating Serendipity
Serendipitous retrieval takes place in the context of browsing or searching a digital information space
people immerse themselves in the items that interest them, meandering from topic to topic while concurrently recognizing interesting and informative information en route.
The connections we make when trying to creatively solve a problem is often serendipitous
Conclusion
The inclusion of the creative process in information retrieval systems and in particular in digital libraries.
Serendipitous retrieval demands approaching information retrieval in an unorthodox manner
While significant evidence exist to support the value of serendipitous experiences,
