Abstraction	Subdomain	Description
Acknowledgment index	ScientometricsContribution Indicators	A scientometric index of named support and influence in scholarly acknowledgments, exposing funding, technical, collegial and institutional contributions that citation counts do not capture.
Bibliographic Coupling	BibliometricsScientometrics	A document-pair relation based on shared cited references, often weighted by the size of their reference-set overlap.
Cluster Labeling	Document ClusteringCluster Interpretation	Attaching interpretable descriptions to computed groups so people can navigate and evaluate their meaning.
Co-citation	BibliometricsCitation Analysis	A relation between two cited works measured by how many other works cite both within a specified corpus.
Controlled Vocabulary	Knowledge OrganizationIndexing	A maintained knowledge-organization vocabulary whose authorized terms and concept relations support consistent description and retrieval despite synonymy, homography, and polysemy.
Digital reference services	Reference Services	Remote, computer-mediated librarian assistance with a user's information need.
Enterprise content management	Information Management	An organizational discipline and system architecture for capturing, governing, storing, preserving and delivering content across its lifecycle and business processes.
Faceted Classification	Classification Theory	A faceted classification is a classification scheme used in organizing knowledge into a systematic order.
Ghost Character	Character Repertoire Curation	A purportedly distinct written character entered in a character inventory or encoding through a source-lineage error rather than a securely attested character in the claimed tradition.
H-index	Bibliometrics and Research Evaluation	A bibliometric index equal to the largest integer h for which an author or other publication set has at least h works cited at least h times each.
I-Space (conceptual framework)	Knowledge Management	A knowledge-management framework relating information's codification, abstraction and diffusion through a three-dimensional space and social learning cycle.
Ignorance management	Knowledge Management	An organizational practice that makes unknowns, knowledge limits, suppressed questions, and missing expertise explicit so they can be prioritized, shared, investigated, or deliberately tolerated.
Information Need	Information Behavior	Represent the situated gap between what an actor currently knows and what the actor must know to interpret, decide, or act, allowing the gap to evolve from unarticulated unease into a formal question and system-facing query.
Information Seeking	Information Behavior	Goal-directed human activity that begins with a perceived information need and proceeds through source selection, searching, encountering, evaluating, using, and sometimes abandoning information across formal and informal channels.
Knowledge organization system	Knowledge Organization Systems	A governed concept scheme that selects concepts, records semantic relations among them, and supports organizing, managing, and retrieving knowledge.
Known-item search	Information Retrieval	Known-item search is retrieval undertaken with a particular target item already in mind and identifiable by attributes such as author or title.
Literature Review	Research SynthesisLiterature Searching	A literature review is a documented scholarly process and resulting account that identifies a question or topic, searches for relevant works, applies inclusion and appraisal criteria, organizes findings, synthesizes agreements and disagreements, and locates gaps or implications.
Literature-Based Discovery	Knowledge Discovery from Literature	Generate testable hypotheses by linking complementary relations stated in separate scholarly literatures—often A–B and B–C—to propose an unstated A–C connection.
Medical Subject Headings	Controlled VocabulariesBiomedical Indexing	The National Library of Medicine's controlled biomedical indexing vocabulary, combining descriptors, hierarchical tree positions, qualifiers, publication types, and supplementary concept mappings.
Metabibliography	BibliographyBibliographic Control	A bibliography whose selected bibliographic units are themselves bibliographies, creating a second-order route from an information need to the finding aids that cover relevant documents.
Metadata standard	Information Management	A shared specification defining metadata elements, meanings, structures and rules so information can be interpreted and exchanged consistently.
Naming System	Information OrganizationNomenclatureIdentifiers	A naming system is a governed scheme of namespaces, formation rules, assignment authority, uniqueness or interpretability constraints, and lifecycle procedures for creating, resolving, changing, and retiring names or identifiers within a declared domain.
Open access (publishing)	Scholarly CommunicationPublishing Models	the authors of research papers are not paid in any way, so they do not suffer any monetary losses, when they switch from behind paywall to open access publishing, especially, if they use diamond open access media.
Open-access citation advantage	Bibliometrics and Scholarly CommunicationScience of Science	A context-dependent excess of citations to open-access scholarly works over a specified non-open comparison group.
OpenURL Knowledge Base	Link ResolversElectronic Resource Management	A maintained database of electronic-resource packages, titles, coverage, identifiers, linking syntax, and local activations used to route a citation to an institution-appropriate accessible copy.
Organizational memory	Knowledge Management	The accumulated, retrievable knowledge of an organization preserved in people, routines, records, artifacts, and information systems.
Patent map	Patent InformaticsPatent Landscaping	A graphical or spatialized analysis of patents in a defined technology field, used to display clusters, relationships, ownership, chronology, whitespace, or possible infringement-relevant overlap under documented search and similarity choices.
Records continuum model	Archival Science	An archival model treating record creation, capture, organization, and pluralization as simultaneous interacting dimensions rather than sequential life stages.
SECI model of knowledge dimensions	Knowledge Management	An organizational knowledge-creation model cycling between socialization, externalization, combination and internalization to convert tacit and explicit knowledge.
Signature mark	Analytical BibliographyBookbinding	A printed letter, number, or symbol placed on an early leaf of a book gathering so sections can be collated in the intended order before binding.
UNISIST Model	Scholarly Communication	A library-and-information-science model of scholarly communication that traces knowledge from producers through formal and informal channels, documentary products, and intermediary services to users.
Units of Information	Information Theory	Choose a logarithmic reference base and unit convention for information quantities so the same amount can be expressed coherently in bits or shannons, nats, hartleys, and their standardized multiples without confusing information with storage capacity.
Universal Bibliographic Control	Bibliographic ControlCataloging	Current UBC practice is developed by IFLA's Bibliography Section.
Web navigation	Information Architecture	Movement through linked web information using global, local, contextual and supplemental pathways exposed by a browser interface.
