  Green, R.: Facet analysis and semantic frames.
  In: Knowledge organization. 44(2017) no.6, S.397-404.
  
  Abstract: Various fields, each with its own theories, techniques, and tools, are concerned with identifying and representing the conceptual structure of specific knowledge domains. This paper compares facet analysis, an analytic technique coming out of knowledge organization (especially as undertaken by members of the Classification Research Group (CRG)), with semantic frame analysis, an analytic technique coming out of lexical semantics (especially as undertaken by the developers of Frame-Net) The investigation addresses three questions: 1) how do CRG-style facet analysis and semantic frame analysis characterize the conceptual structures that they identify?; 2) how similar are the techniques they use?; and, 3) how similar are the conceptual structures they produce? Facet analysis is concerned with the logical categories underlying the terminology of an entire field, while semantic frame analysis is concerned with the participant-and-prop structure manifest in sentences about a type of situation or event. When their scope of application is similar, as, for example, in the areas of the performing arts or education, the resulting facets and semantic frame elements often bear striking resemblance, without being the same; facets are more often expressed as semantic types, while frame elements are more often expressed as roles.

  Green, R.: Indigenous Peoples in the U.S., sovereign nations, and the DDC.
  In: Knowledge organization. 42(2015) no.4, S.211-221.
  
  Abstract: Claims of bias within the Dewey Decimal Classification (DDC) system in its treatment of indigenous peoples in the U.S. focus on marginalization through ghettoization, historicization, diasporization, and missing topics, such as the status of indigenous peoples as sovereign nations. Investigation into the treatment of indigenous peoples in the U.S. from DDC 16 to DDC 23 reveals that two of the most central concerns, ghettoization and historicization, are not borne out. Diasporization turns out to be a legitimate, but resolvable, concern. The current failure to recognize indigenous peoples as sovereign nations leads to a proposal for a series of expansions in Table 2 for the geographic areas over which indigenous peoples are sovereign; a mismatch between organization by the DDC and by indigenous peoples in the U.S. leads to the supplying of a Manual note table going from names of tribes (a Table 5 concept) to sovereign nations (a Table 2 concept).

  Green, R.: Relational aspects of subject authority control : the contributions of classificatory structure.
  In: Classification and authority control: expanding resource discovery: proceedings of the International UDC Seminar 2015, 29-30 October 2015, Lisbon, Portugal. Eds.: Slavic, A. u. M.I. Cordeiro. Würzburg : Ergon-Verlag, 2015. S.39-52.
  
  Abstract: The structure of a classification system contributes in a variety of ways to representing semantic relationships between its topics in the context of subject authority control. We explore this claim using the Dewey Decimal Classification (DDC) system as a case study. The DDC links its classes into a notational hierarchy, supplemented by a network of relationships between topics, expressed in class descriptions and in the Relative Index (RI). Topics/subjects are expressed both by the natural language text of the caption and notes (including Manual notes) in a class description and by the controlled vocabulary of the RI's alphabetic index, which shows where topics are treated in the classificatory structure. The expression of relationships between topics depends on paradigmatic and syntagmatic relationships between natural language terms in captions, notes, and RI terms; on the meaning of specific note types; and on references recorded between RI terms. The specific means used in the DDC for capturing hierarchical (including disciplinary), equivalence and associative relationships are surveyed.

  In: Knowledge organization. 41(2014) no.4, S.327-331.
  (Feature)
  
  Abstract: The main idea of this panel was to create a platform for discussing knowledge organization in the past, present, and future within ISKO. During the panel discussion the following three questions were asked: 1) What is knowledge organization (KO)? 2) What changes do you foresee in the future that will prove to be the most challenging for ISKO? 3) What is your ideal picture of what the ISKO of the future could be? How do we get there?

  Abstract: Because procedures for establishing facets tend toward subjectivity, this pilot project investigates whether the facet structure of a subject literature can be discerned automatically on the basis of its own metadata. Nouns found in the titles of works retrieved from the WorldCat bibliographic database based on Dewey number are mapped against the nodes of the WordNet noun network. Density measures are computed for these nodes to identify nodes best summarizing the title noun data / best corresponding to facets of the subject. Results of the work to date are promising enough to warrant further investigation.

  Green, R.: See-also relationships in the Dewey Decimal Classification.
  In: Knowledge organization. 38(2011) no.4, S.335-341.
  
  Abstract: This paper investigates the semantics of topical, associative see-also relationships in schedule and table entries of the Dewey Decimal Classification (DDC) system. Based on the see-also relationships in a random sample of 100 classes containing one or more of these relationships, a semi-structured inventory of sources of see-also relationships is generated, of which the most important are lexical similarity, complementarity, facet difference, and relational configuration difference. The premise that see-also relationships based on lexical similarity may be language-specific is briefly examined. The paper concludes with recommendations on the continued use of see-also relationships in the DDC.

  Green, R. ; Panzer, M.: Relations in the notational hierarchy of the Dewey Decimal Classification.

  Abstract: As part of a larger assessment of relationships in the Dewey Decimal Classification (DDC) system, this study investigates the semantic nature of relationships in the DDC notational hierarchy. The semantic relationship between each of a set of randomly selected classes and its parent class in the notational hierarchy is examined against a set of relationship types (specialization, class-instance, several flavours of whole-part).The analysis addresses the prevalence of specific relationship types, their lexical expression, difficulties encountered in assigning relationship types, compatibility of relationships found in the DDC with those found in other knowledge organization systems (KOS), and compatibility of relationships found in the DDC with those in a shared formalism like the Web Ontology Language (OWL). Since notational hierarchy is an organizational mechanism shared across most classification schemes and is often considered to provide an easy solution for ontological transformation of a classification system, the findings of the study are likely to generalize across classification schemes with respect to difficulties that might be encountered in such a transformation process.

  Abstract: WordNet, a lexical database for English, is organized around semantic and lexical relationships between synsets, concepts represented by sets of synonymous word senses. Offering reasonably comprehensive coverage of the nouns, verbs, adjectives, and adverbs of general English, WordNet is a widely used resource for dealing with the ambiguity that arises from homonymy, polysemy, and synonymy. WordNet is used in many information-related tasks and applications (e.g., word sense disambiguation, semantic similarity, lexical chaining, alignment of parallel corpora, text segmentation, sentiment and subjectivity analysis, text classification, information retrieval, text summarization, question answering, information extraction, and machine translation).

  Green, R.: Relationships in knowledge organization.
  In: Knowledge organization. 35(2008) nos.2/3, S.150-159.
  
  Abstract: Relationships that interconnect entity classes of import to knowledge organization (knowledge, documents, concepts, beings, information needs, language) include both non-subject bibliographic relationships (document-to-document relationships, responsibility relationships) and conceptual content relationships (subject relationships, relevance relationships). While the MARC format allows the recording of most bibliographic relationships, many of them are not expressed systematically. Conceptual content relationships include, in turn, interconcept and intraconcept relationships. The expression of interconcept relationships is covered by standard thesaural relationships, which typically do not distinguish fully between the underlying lexical relationship types. The full expression of complex intraconcept relationships includes indication of the basic nature of the relationship (including a set of semantic roles), the set of entities that participate in the relationship, and a mapping between participants and semantic roles. Knowledge organization schemes seldom express these relationships fully.

  Inhalt: Relative Index (RI) terms in the Dewey Decimal Classification (DDC) system correspond to concepts that either approximate the whole of the class they index or that are in standing room there. DDC conventions and shallow natural language processing are used to determine automatically whether specific RI terms approximate the whole of or are in standing room in the classes they index. Approximately three-quarters of all RI terms are processed by the techniques described.

  Abstract: EPC Exhibit 129-36.1 presented intermediate results of a project to connect Relative Index terms to topics associated with classes and to determine if those Relative Index terms approximated the whole of the corresponding class or were in standing room in the class. The Relative Index project constitutes the first stage of a long(er)-term project to instill a more systematic treatment of relationships within the DDC. The present exhibit sets out a plan of study for that long-term project.

  Abstract: Semantic types provide a level of abstraction over particulars with shared behavior, such as in the participant structure of semantic frames. The paper presents a preliminary investigation, drawing on data from WordNet and FrameNet, into the relationship between hierarchical level and the semantic types that name frame elements (a.k.a. slots). Patterns discovered include: (1) The level of abstraction of a frame is generally matched by the level of abstraction of its frame elements. (2) The roles played by persons tend to be expressed very specifically. (3) Frame elements that mirror the name of the frame tend to be expressed specifically. (4) Some frame participants tend to be expressed at a constant (general) level of abstraction, regardless of the level of abstraction of the overall frame.

  Abstract: Although less well studied than noun polysemy, verb polysemy affects both natural language and controlled vocabulary searching. This paper reports the preliminary conclusions of an empirical investigation of the semantic relationships between ca. 600 verb sense pairs in English, illustrating six classes of semantic relationships that account for a significant proportion of verbal polysemy.

  Abstract: Within the overall conference theme-integration of knowledge across boundaries-an important subtheme is universality: Where universals of knowledge organization and representation exist, knowledge integration is more likely. Thus, knowledge of conceptual universals should inform efforts at knowledge integration. In this paper, natural language is used as a model for exploring conceptual universals, since the phenomenon of translating between languages validates, but also circumscribes, the existence of semantic and lexical universals. The paper explores a representative inventory of semantic and lexical universals that should be accounted for in knowledge organization and representation systems, especially those that aim to be comprehensive.

  Abstract: This paper examines whether a concept's hierarchical level affects the likelihood of its universality across schemes for knowledge representation and knowledge organization. Empirical data an equivalents are drawn from a bilingual thesaurus, a pair of biomedical vocabularies, and two ontologies. Conceptual equivalence across resources occurs significantly more often at the basic level than at subordinate or superordinate levels. Attempts to integrate knowledge representation or knowledge organization tools should concentrate an establishing equivalences at the basic level. 1. Rationale The degree of success attainable in the integration of multiple knowledge representation systems or knowledge organization schemes is constrained by limitations an the universality of human conceptual systems. For example, human languages do not all lexicalize the same set of concepts; nor do they structure (quasi-)equivalent concepts in the same relational patterns (Riesthuis, 2001). As a consequence, even multilingual thesauri designed from the outset from the perspective of multiple languages may routinely include situations where corresponding terms are not truly equivalent (Hudon, 1997, 2001). Intuitively, where inexactness and partialness in equivalence mappings across knowledge representation schemes and knowledge organizations schemes exist, a more difficult retrieval scenario arises than where equivalence mappings reflect full and exact conceptual matches. The question we address in this paper is whether a concept's hierarchical level af ects the likelihood of its universality/full equivalence across schemes for knowledge representation and knowledge organization. Cognitive science research has shown that one particular hierarchical level-called the basic level--enjoys a privileged status (Brown, 1958; Rosch et al., 1976). Our underlying hypothesis is that concepts at the basic level (e.g., apple, shoe, chair) are more likely to match across knowledge representation schemes and knowledge organization schemes than concepts at the superordinate (e.g., fruit, footwear, furniture) or subordinate (e.g., Granny Smith, sneaker, recliner) levels. This hypothesis is consistent with ethnobiological data showing that folk classifications of flora are more likely to agree at the basic level than at superordinate or subordinate levels (Berlin, 1992).

  Abstract: The basic conceptual units of cognitive semantics-image schemata, basic level concepts, and frames-are intemally structured, with meaningful relationships existing between components of those units. In metonymy, metaphor, and blended spaces, such intemal conceptual structure is complemented by extemal referential structure, based an mappings between elements of underlying conceptualspaces.

  Abstract: Relationships are specified by simultaneously identifying a semantic relationship and the set of participants involved in it, pairing each participant with its role in the relationship. Properties pertaining to the participant set and the nature of the relationship are explored. Relationships in the organization of knowledge are surveyed, encompassing relationships between units of recorded knowledge based an descriptions of those units; intratextual and intertextual relationships, including relationships based an text structure, citation relationships, and hypertext links; subject relationships in thesauri and other classificatory structures, including relationships for literature-based knowledge discovery; and relevance relationships.

  (Information science and knowledge management; vol.2)
  
  Abstract: Relevance arises from relationships between user needs and documents/information. In the quest for relevant retrieval, some content-based relationships are best used initially to cast a net that emphasizes recall, while others, both content- and non-content-based, are best used subsequently as filtering devices to achieve better precision. Topical relevance, the primary factor in the initial retrieval operation, extends far beyond topic matching, as often assumed. Empirical studies demonstrate that topical relevance relationships are drawn from a broad but systematic inventory of semantic relationships.
