Quotes from Arlene G. Taylor

Natural language processing (NLP) research aims to enable computers to interpret and react to human languages.

Metadata, in its most informal but most prevalent definition, is "data about data.

This means that the attributes used to describe an information resource are metadata about that resource.

Bibliographic control (more often referred to as information organization today) is the process of describing information resources and providing name, title, and subject access to the descriptions, resulting in records or individual metadata statements that serve as surrogates for the actual items of recorded information.

Metadata is stored in a variety of retrieval tools (a collective term used to describe bibliographies, catalogs, indexes, finding aids, museum registers, bibliographic databases, search engines, and other tools that help users find information resources).

An access point is a name, word, phrase, or identifier chosen by a cataloger or indexer and placed in a particular field in a record that describes a

Ontologies have been variously construed as classification schemes, taxonomies, hierarchies, thesauri, controlled vocabularies, terminologies and even dictionaries. While they may display characteristics reminiscent of each of these systems, to equate ontologies with any one type of representational structure is to diminish both their function and their potential in the evolution of the Semantic Web.44

According to Marcia Lei Zeng and Jian Qin, an ontology describes (a)the types of things that exist (classes), (b)the relationships between them (properties), and (c)the logical ways those classes and properties can be used together (axioms).46

The broadest usage of the term is for a formal representation or specification of what is common sense or objective reality to a human being.

It is created to keep conceptual and semantic ambiguity at a minimum in an information and technological environment, which is something that is not always possible with traditional controlled vocabularies.

Although the relationships among them are not explicitly defined, there is no doubt that these terms and the vocabulary's syndetic structure can be helpful when retrieving resources within a database or catalog.

The use of standardized terms and relationship indicators allows for successful searching and navigation.
