The library and the Information Center

In libraries and information centers, knowledge organization systems serve as bridges between the user's information requirements and the materials in the collection.

The situation of a user that faces an information retrieval task has some similarities to that of a learner. Both "learning" situations have something in common, these are mainly knowledge management tasks. The user must navigate in a structured organization of knowledge to reach an end point, understand and select.

Knowledge organization is fundamental to guarantee the user's access to materials in the collection, but most resources, like thesaurus, are compiled by specialists for specialists, so the average user, like students, researchers, politicians, lawyers, even casual users strive to create an acceptable-to-optimal search strategy. They search to know, but to search they must know.

Thesaurus are still an object developed following practical considerations, practically unchanged after several decades, and they attempt to represent the knowledge structure transferred by authors (as translated by thesaurus officials and indexers).

The main goal of a thesaurus is to control and structure vocabulary to guarantee indexing coherence and retrieval efficacy, though it still could be used (or it is part of the intention) to help users understand a specific domain (offering semantic maps), showing concepts interrelationships, and helping to formalize  the definition of terms.

Thesaurus can also be used as a vocabulary acquisition tool and to activate thinking at online searching time.

The thesaurus is above all an expression of a specialized technical language and classification schemes from a lab or team, or of a domain in which the thesaurus sediments practical experience and ideas. In this sense, it is a deliberately rigid view (deformed, false and distorted) of the world. The natural user of a thesaurus is the indexer, not the end user.


Facilitating user interaction with the "knowledge base"

The user of a library or information or documentation center  already has a mental scheme of the world, thinks in natural language. In his mind, the contents to be located or identified are not represented by a narrow set of descriptors, but by concepts and relations. Therefore, matching his information needs from his mental scheme to a restricted set of concept-descriptors (or preferred terms) might not work, ending in frustration, delusion and worse. The task fails. A classical case of semantic noise.

The user's knowledge is structured in many conceptual categories and with many relation types, not only hierarchical and (full or partial) synonymy, but mainly associative. Why start from a specific concept from a list when any "relevant" concept would may ease the search formation; for most users this strategy might even lead to reconfiguring information needs and to direct learning.

The separation of knowledge domains is artificial. A holistic approach to knowledge organization could also benefit exploration of knowledge bases, if the thesaurus (or knowledge organization interface) has qualified links to other knowledge domains (if knowledge organization must represent the wealth of scientific literature).



The role of Knowledge Master in the knowledge organization of information systems.

Knowledge Master produces conceptual knowledge bases.

In a traditional thesaurus, the meaning of a descriptor responds to pragmatic considerations of efficacy in retrieval, and to communication practice internal to the small group using the system. On the other hand a
Knowledge Master conceptual knowledge base tends (or is prepared to) reflect the psychological structure of knowledge, that of the user trying to build a search strategy.

Knowledge Master's conceptual knowledge bases handle concepts and relations in the same way a thesaurus or an equivalent knowledge organization interface does, but:

punto elenco

it produces knowledge bases with a graphical interface, an evolution of semantic networks, that aids perception.

punto elenco

this structure is closer to the user's mind organization

punto elenco

these knowledge bases, endowed with a graphical interface can be multilayered, adding another knowledge qualification facet, the context.

punto elenco

this graphical interface aids user perception of the knowledge structure

punto elenco

with semantic paths higher level concepts can be illustrated, passing the marker on a path of the map, that produces a full search enunciate

punto elenco

semantic paths can be reused

punto elenco

has internal search functions on each structural component of the knowledge base

punto elenco

this graphical organization facilitates the discovery of new relations, and a better knowledge of the domain: this could improve the search experience and results

punto elenco

it can be used to link a digital resource to related material.

punto elenco

it can host any domain knowledge

punto elenco

it eases the construction of the search strategy

punto elenco

the cognitive use of voice offers an additional communication channel.

Searching, or constructing a search strategy is a personal goal-directed behavior, aimed not only at satisfying the user's informational needs but also to developing the average user's library proficiency. It inducts basic cognitive processes in search behavior and intellectual problem solving.

Other advantages:

punto elenco

Using a conceptual knowledge base, closer to natural language (and therefore to the searcher's mental scheme), brings the user nearer to the contents to be searched.

punto elenco

Descriptors in the knowledge base can also be controlled.

punto elenco

It adapts to user behavior as described in contemporary psychology.

punto elenco

Concept description is directly linked to concept itself.

punto elenco

Offers a friendlier, attractive and meaningful interface, a direct handling interface.

punto elenco

Direct cognitive indexing and hypertext-like retrieval.

punto elenco

A conceptual knowledge base can contain conceptual, declarative and procedural knowledge.

punto elenco

The robust concept descriptions that can be produced with KM, represent more closely the concepts in our mind that can be achieved with traditional concept mapping.

punto elenco

Conceptual knowledge bases can be managed at a distance.

Knowledge Master is an excellent tool to train librarians and information specialists and users.

Paradoxically, in the so-called "information age” the information experts, and the functions they perform (corporate libraries, information centers, records center, archives, are in danger of being left behind. Sometime librarians operate under an obsolete conceptual model and operate as if the library was a warehouse…



The application of knowledge management systems, methods and strategies for searching in libraries and information centers; knowledge management systems can serve as bridges between a user's information needs and the material in a collection.
