Information seeking (or searching)
"Information seeking has been understood as a process in which the actor's understanding of his or her tasks or problems, information needs, relevance criteria, and the available information space evolve." (Järvelin & Ingwersen, 2004).
Information seeking is broader than literature searching and information retrieval. The last mentioned concept is mainly used for searching electronic databases, although it may also be used about searching other systems of organized knowledge (to retrieve means to find again implying that something has first been stored).
Information seeking includes many forms of behavior such as browsing, observing, using informal information sources, reading, studying, searching formal information sources, subscribing to mass media and much more. Searching behavior is not limited to human beings, but is also studied by biologists in different species (cf., Bell, 1991).
Information seeking is an extremely broad term, much broader than Library and Information Science (LIS). For LIS is the point of departure literature searching because literature is what libraries and bibliographic databases are mainly about. (Even so-called fact retrieval sources may be seen as forms of literature).
Tom Wilson makes a distinction between seeking and searching and finds that “the various areas of research within the general area of information behaviour may be seen as a series of nested fields” (Wilson, 1999, p. 262-263):
Information behavior is the overall field
Information seeking is “concerned with the variety of methods people employ to discover, and gain access to information resources” (Wilson, 1999, p. 263).
Information searching is “the interactions between information user (with or without intermediary) and computer-based information systems” (Wilson, 1999, p. 263).
To guide people searching literature is an important task for LIS. This is essential in user education and training. Bibliographical guides are developed to help fulfill this task. Studies of literature searching may be more less descriptive, theoretical or normative. In the library tradition there have been a tendency to provide normative guidelines for both indexing and searching at the expense of research studies. Among the publications about literature searching are: Cooper (1985), Hjørland (1986/1988), White (1994) and Wilson (1992).
Why has information seeking become a popular term in LIS at the expense of literature searching? One very popular researcher in information seeking was Elfreda A. Chatman (†2002). A summary of her book The Information World of Retired Women (1992) is "Using profiles of women living in a retirement community, the information and social worlds of elderly women are explored in an attempt to discover the effects of ageing on their help-seeking behaviour. The relationships between this behaviour and information policy is also discussed."
Within research in artificial Intelligence
is the concept of search also important. There are here two kinds of searches:
Algorithmic searches and
heuristics searches.
An example of a search algorithm is "Brute-Force Search" (which do not
require domain specific knowledge). Subcategories are "Breath-First Search",
"Depth-First Search", "Depth-First Iterative-Deepening" and "Bidirectional
Search". Examples of algorithms using heuristic evaluations are "Hill-Climbing", "Best-First Search", "A*"
and
"Interactive Deepening-A*" (see Korf, 1987).
Krauthammer et al. (2002) writes that it is often assumed that the correct
molecular interactions are known or can be identified by reading a few research
articles. However, this assumption does not necessarily hold, as truth is rather
an emerging property based on many potentially conflicting facts.
Buzikashvili (2005) considers different types of model and real-life information searching behavior. Only two behavioral principles correspond to all the diversity of information searching: the principle of least effort describing a model unmediated search and the principle of guarantied results describing a model mediated search. It is shown that real-life searching follows the same principles and that the principle of least effort describes not only unmediated search but also team and pseudo-mediated searches. To explain information searching behavior the coverage space is considered. This model explains both choice of the principle and non-monotonicity of this choice. As an application of these results, the universally accepted myth about differences between searching on the Web and searching in traditional IR systems is reevaluated.

Information Begrebet informationssøgning anvendes i forskellige betydninger, der bl.a.
hænger sammen med uklarhed omkring begrebet *"information". Nogle gange anvendes
det som *"fact retrieval" i modsætning til dokumentsøgning (*"information
retrieval"; "IR"). Denne begrebsbrug vil vi ikke anbefale (jfr. *information).
Informationssøgning dækker såvel litteratursøgning som søgning efter konkrete
oplysninger og viden i ikke-dokumenteret form, herunder såvel emnesøgning som
"non-subject search" (Jfr. *emnesøgning).
Begrebet dækker såvel *manuel- som automatiseret søgning, hvorimod
betegnelsen "information retrieval" har en konnotation i retning af
automatiseret søgning eller søgning i elektroniske medier. I dette leksikon vil
vi forsøge at foretage en sondering mellem de problemer, der er mere umiddelbart
knyttet til tekniske og formelle aspekter i "IR" og de problemer vedr. f.eks.
forskeres brug af *kilder, der mere går på søgningens indholdsmæssige,
kvalitative, forskningsmetodologiske side. Vi opfatter begrebet
informationssøgning som bredere og mere overordnet in IR, men nogen skarp grænse
eller konsekvens vil ikke blive trukket. Informationssøgning forudsætter først
og fremmest kendskab til *informationsstrukturer, *vidensdomæner, fagsprog
o.lign. Bogen "Information Seeking" (Chen & Hernon, 1982) er et typisk eksempel
på en bog om informationssøgning, der kan adskilles fra den snævrere litteratur
om *"information retrieval", der f.eks. er repræsenteret ved forfattere som
Cleverdon, Salton, Spark Jones og Lancaster.
Informationssøgning - og muligheden for at optimere denne ved
*dokumentbeskrivelse, *vidensrepræsentation, *"IR-sprog" o.s.v. udgør
*informationsvidenskabens nøgleproblem.
Nogle gange konstruerer bibliotekarer søgediagrammer, der rummer normative
anvisninger på, hvorledes informationssøgning skal foretages (Se nærmere under
*algoritme).
