A thesaurus may be viewed as a graph, and document retrieval algorithms can exploit this graph when both the documents and the query are represented by thesaurus terms. These retrieval algorithms measure the distance between the query and documents by using the path lengths in the graph. Previous work with such strategies has shown that the hierarchical relations in the thesaurus are useful but the non‐hierarchical relations are not. This paper shows that when the query explicitly mentions a particular non‐hierarchical relation, the retrieval algorithm benefits from the presence of such relations in the thesaurus. Our algorithms were applied to the Excerpta Medica bibliographic citation database whose citations are indexed with terms from the EMTREE thesaurus. We also created an enriched EMTREE by systematically adding non‐hierarchical relations from a medical knowledge base. Our algorithms used at one time EMTREE and, at another time, the enriched EMTREE in the course of ranking documents from Excerpta Medica against queries. When, and only when, the query specifically mentioned a particular non‐hierarchical relation type, did EMTREE enriched with that relation type lead to a ranking that better corresponded to an expert's ranking.

The purpose of this paper, which increases and deepens what was expressed in a previous work (Mazzocchi et al., 2007), is to scrutinize the underlying assumptions of the types of relations included in thesauri, particularly the genus-species relation. Logicist approaches to information organization, which are still dominant, will be compared with hermeneutically oriented approaches. In the light of these approaches, the nature and features of the relations, and what the notion of a priori could possibly mean with regard to them, are examined, together with the implications for designing and implementing knowledge organizations systems (KOS).

The inquiry is based on how the relations are described in literature, engaging in particular a discussion with Hjørland (2015) and Svenonius (2004). The philosophical roots of today’s leading views are briefly illustrated, in order to put them under perspective and deconstruct the uncritical reception of their authority. To corroborate the discussion a semantic analysis of specific terms and relations is provided too.

All relations should be seen as “perspectival” (not as a priori). On the other hand, different types of relations, depending on the conceptual features of the terms involved, can hold a different degree of “stability.” On this basis, they could be used to address different information concerns (e.g. interoperability vs expressiveness).

Some arguments that the paper puts forth at the conceptual level need to be tested in application contexts.

This paper considers that the standpoint of logic and of hermeneutic (usually seen as conflicting) are both significant for information organization, and could be pragmatically integrated. In accordance with this view, an extension of thesaurus relations’ set is advised, meaning that perspective hierarchical relations (i.e. relations that are not logically based but function contingently) should be also included in such a set.

The purpose of this paper is to investigate indexers’ evaluation on the usability of ontology vs thesaurus in representation of concepts and semantic relations. To do so, “searching” category of ASIS&T thesaurus was selected and ASIS&TOnto was built based on it.

The usability examination method is used in order to compare the two semantic tools. Nine indexers were recruited as participants, who were proficient in English language, had experience in using the thesaurus and all had successfully passed the course of “information representation.” They were asked to think aloud while working with the tools and to answer a semi-structured interview. The data gathering was continued until it reached its saturation point.

The results of this study revealed that the definitions and scope notes represented in indexing tools such as thesauri and ontologies have an important role in improvement of indexers’ understanding. On comparing the hierarchical relations, results show that converting the structure of hierarchical relationships of ASIS&T thesaurus can enhance the indexers understanding of them, and also enriching the associative relations of ASIS&T thesaurus can cause indexers to have a better understanding and evaluation of the presented concepts and relations.

This study shares our findings on the usability of ASIS&T thesaurus as a core set of vocabulary for building a “searching” domain as a prototype ontology in the area of library and information science and provides the indexers viewpoints of the two semantic tools in this area.

Problem-solving” is the most crucial key insight of scientific research. This study focuses on constructing the “problem-solving” knowledge graph of scientific domains by extracting four entity relation types: problem-solving, problem hierarchy, solution hierarchy and association.

This paper presents a low-cost method for identifying these relationships in scientific papers based on word analogy. The problem-solving and hierarchical relations are represented as offset vectors of the head and tail entities and then classified by referencing a small set of predefined entity relations.

This paper presents an experiment with artificial intelligence papers from the Web of Science and achieved good performance. The F1 scores of entity relation types problem hierarchy, problem-solving and solution hierarchy, which were 0.823, 0.815 and 0.748, respectively. This paper used computer vision as an example to demonstrate the application of the extracted relations in constructing domain knowledge graphs and revealing historical research trends.

This paper uses an approach that is highly efficient and has a good generalization ability. Instead of relying on a large-scale manually annotated corpus, it only requires a small set of entity relations that can be easily extracted from external knowledge resources.

Considering the shortcomings of the ASIS&T Web-based thesaurus in representing concepts and semantic relations, there is a need to use more effective semantic tools, such as ontologies. The purpose of this paper is to build a prototype ontology (ASIS&TOnto) based on a Web-based thesaurus.

The prototype ontology was built based on the ASIS&T Web-based thesaurus by using the methodology developed by Noy and McGuinness (2001) and with the use of Protégé 4.3.3. With regard to the purpose of the study and the massive amount of concepts represented in the ASIS&T thesaurus, the focus of term selection for creating the core source of vocabulary for the prototype ontology was the “searching” area. The knowledge engineering approach (Na and Neoh, 2008) was used to extract concepts and semantic relations. The criterion for extracting semantic relations from each concept pair was one-sentence statement, one-paragraph statement and one-page statement. Finally, the extracted relations were analysed by subject experts.

Based on the findings of this research, the possibility of using the methodology developed by Noy and McGuinness (2001) for building an ontology based on a Web-based thesaurus in the field of LIS was investigated and the prototype ontology (ASIS&TOnto) was constructed in the area of “searching”.

The primary implication of ASIS&TOnto is aligned with Web 3.0 research where implications of semantic modelling are a priority for community equity of access to information as a basic human right. ASIS&TOnto ends up with an ontology that is comprehensive, at least with respect to expressivity of the current ASIS&T thesaurus user interface definition languages; that is, it can be universal and can be extendable to future user interfaces that do not exist at the moment.

For the first time, a new enriched semantic tool (ASIS&TOnto) was constructed based on the ASIS&T Web-based thesaurus.

The #MeToo movement has brought questions of sexuality and power in the workplace to the forefront. The purpose of this paper is to review the research on hierarchial consensual workplace romances and sexual harassment examining the underlying mechanisms of power relations. It concludes with a call to action for organizational leaders to adopt fair consensual workplace romance policies alongside strong sexual harassment policies.

This paper represents a conceptual review of the literature on consensual workplace romance, sexual harassment, passive leadership and power relations. Passive leadership leads to a climate of incivility that in turn suppresses disclosures of sexual harassment (Lee, 2016). Consensual workplace romances across hierarchical power relations carry significant risks and may turn into harassment should the romance turn sour.

Two new concepts, sexual hubris and sexploitation, are defined in this paper. Sexual hubris, defined as an opportunistic mindset that allows the powerful to abuse their power to acquire sexual liaisons, and its opposite, sexploitation, defined as a lower-status member using sexuality to gain advantage and favor from an upper-level power target, are dual opportunistic outcomes of an imbalanced power relation. Sexual hubris may increase the likelihood for sexual harassment such that a mindset occurs on the part of the dominant coalition that results in feelings of entitlement. Sexploitation is a micromanipulation tactic designed to create sexual favoritism that excludes others from the power relation.

Sexual hubris and sexploitation are conceptualized as an opportunistic mechanisms associated with imbalanced power relations to spur future research to tease out complex issues of gender, sexuality and hierarchy in the workplace. Sexual hubris serves to protect the dominant coalition and shapes organizational norms of a climate of oppression and incivility. Conversely, sexploitation is a micromanipulation tactic that allows a lower-status member to receive favoritism from a higher-power target. Four research propositions on sexual hubris and sexploitation are presented for future scholarship.

Most organizational leaders believe consensual romance in the office cannot be legislated owing to privacy concerns. Passive leadership is discussed as a leadership style that looks the other way and does not intervene, leading to workplace hostility and incivility (Lee, 2016). Inadequate leadership creates a climate of passivity that in turn silences victims. Policies concerning consensual workplace romance should stand alongside sexual harassment policies regardless of privacy concerns.

The #MeToo movement has allowed victims to disclose sexual misconduct and abuse in the workplace. However, the prevalence of sexual harassment claims most often can be traced to a leadership problem. Employers must recognize that sexual hubris and sexploitation arise from imbalances of power, where sex can be traded for advancement, and that often consensual workplace romances end badly, leading to claims of sexual harassment. Consensual romance policies must stand alongside sexual harassment policies.

Sexual hubris and sexploitation are offered as novel concepts that provide a mechanism for conceptualizing the potential for abuse and manipulation from unbalanced power relations. These are original concepts derived from the arguments within this paper that help make the case for consensual workplace romance policies alongside sexual harassment policies.

The purpose of this paper is to investigate interorganizational knowledge exchange from the perspective of the individual manager/professional. The paper aims to study the kinds of relationships managers/professionals in SMEs are involved in and the way in which they construct boundaries within and around these interorganizational relationships enabling and hindering knowledge acquisition.

The paper is based on 31 interviews with managers and professionals in seven SMEs. Interviews focused on the interorganizational relationships they viewed as important sources of knowledge for themselves and their organizations.

The study shows that managers/professionals gain vital knowledge from far more interorganizational relationships than those formally designed for knowledge acquisition. The most important sources of knowledge were relationships with suppliers and customers. The study also identifies five boundary dimensions – interests, interpretive frameworks, trust, private/organizational and priority – which respondents use in constructing boundaries within and around the relationships. These boundary dimensions represent important conditions for knowledge acquisition through the relationship.

The five boundary dimensions are generated based on a sample of SMEs in Sweden. They must thus be regarded as provisional and need to be validated in further research including larger organizations in different cultural contexts. Future studies should also focus on the dynamics of the boundaries and their interrelations as relationships evolve.

This paper adds to research on interorganizational knowledge acquisition by taking an individual level perspective and identifying boundary dimensions through which the relationships and their knowledge flows are shaped.

This chapter describes the change efforts and action research projects at a Dutch multinational which, over a period of 25 years, produced in one of its businesses a zigzag path toward collaborative leadership dynamics at the horizontal and vertical interfaces. The chapter also identifies the learning mechanisms that helped achieve this transformation. Changing the patterns at the vertical interfaces proved to be a most tricky, complex, and confusing operation. The data show that organizations need hierarchical interfaces between levels, but are hindered by the hierarchical leadership dynamics at these interfaces. The data furthermore show that competitive performance requires more than redesigning horizontal interfaces. A business can only respond with speed and flexibility to threats and opportunities in the external environment when the leadership dynamics at agility-critical vertical interfaces are also changed.
