Lee, D. ; Robinson, L. ; Bawden, D.: Modeling the relationship between scientific and bibliographic classification for music.
In: Journal of the Association for Information Science and Technology. 70(2019) no.3, S.230-241.

Abstract: Scientific classification is an important topic in contemporary knowledge organization discourse, yet the nature of the relationships between scientific and bibliographic classifications has not been fully studied. This article considers the connections between scientific and bibliographic classifications for music, taking general discourse about scientific classification and domain analysis as its starting point. Three relationship characteristics are posited: similarity, causation, and time. In discussions about similarity, "accords" and "discords" are analyzed. Further, the idea of a scale of accord is introduced, and issues with assuming a univocal scientific or bibliographic classification of music are discussed. Causation and the idea of influence between scientific and bibliographic classifications for music are unpicked. The connections between accordance and influence are explored, and the concept of differing purposes for different classification approaches is analyzed. A temporal dimension is considered, and the dynamic nature of connections between music scientific and bibliographic classifications is established. The idea of bifurcation is introduced-a change of accordance over time-which is prominent for musical instrument classification. The concluding model visualizes similarity, causation and temporal aspects as three dimensions, showing how scientific and bibliographic classifications for music are connected through a set of interconnected and complex relationships.

Freeman, G. ; Glushko, R.J.: Organization, not inspiration : a historical perspective of musical information architecture.
In: Knowledge organization. 46(2019) no.3, S.161-170.

Abstract: The organization of musical resources in a piece of music is opaque for everyone but for those with the highest levels of musical education. For the average listener, the specific vocabulary of musical organization is usually replaced by metaphorical language relating to inspiration and musical affect, or by a social perspective that rids the music of its specific theoretical language and provides a more relatable perspective of the music as a historical and communal event. We examine the ways in which information architecture and organizational theory can surface the inner workings of music in a relatable and approachable way. We consider music as a series of design resources that composers draw upon and organize according to a series of constraints that create a sense of musical structure to which the listener can relate. After a general introduction to the literature relating to constraints and creativity, we use two historical anecdotes that pro-vide accessible demonstrations of how musicians in the seven-teenth and twentieth centuries organized their musical resources both for their own compositional needs and for the purposes of didactic communication.

Wu, S. ; Fan, Y.: Music literature indexing : comparing users' free-text queries and controlled vocabularies.
In: Proceedings of the Association for Information Science and Technology. 54(2017) no.1, S.831-832.

Abstract: This study examined the characteristics of users' free-text queries submitted to RILM Abstracts of Music Literature (a music literature database), and compared those queries with the controlled vocabularies used by RILM. Search-log analysis identified 11 categories of user-created search terms, and mapped each user-created search term to RILM's index terms, assessing whether it was a perfect match, a partial match, or no match. Only 30.04% of the user-created search terms did not match RILM's index terms. Most of the partial-matching and non-matching user-created search terms were personal names, work titles, and topical terms. Suggestions are offered to enhance RILM's controlled vocabularies.

Lee, D. ; Robinson, L.: ¬The heart of music classification : toward a model of classifying musical medium.
In: Journal of documentation. 74(2018) no.2, S.258-277.

Abstract: Purpose The purpose of this paper is to understand the classification of musical medium, which is a critical part of music classification. It considers how musical medium is currently classified, provides a theoretical understanding of what is currently problematic, and proposes a model which rethinks the classification of medium and resolves these issues. Design/methodology/approach The analysis is drawn from existing classification schemes, additionally using musicological and knowledge organization literature where relevant. The paper culminates in the design of a model of musical medium. Findings The analysis elicits sub-facets, orders and categorizations of medium: there is a strict categorization between vocal and instrumental music, a categorization based on broad size, and important sub-facets for multiples, accompaniment and arrangement. Problematically, there is a mismatch between the definitiveness of library and information science vocal/instrumental categorization and the blurred nature of real musical works; arrangements and accompaniments are limited by other categorizations; multiple voices and groups are not accommodated. So, a model with a radical new structure is proposed which resolves these classification issues. Research limitations/implications The results could be used to further understanding of music classification generally, for Western art music and other types of music. Practical implications The resulting model could be used to improve and design new classification schemes and to improve understanding of music retrieval. Originality/value Deep theoretical analysis of music classification is rare, so this paper's approach is original. Furthermore, the paper's value lies in studying a vital area of music classification which is not currently understood, and providing explanations and solutions. The proposed model is novel in structure and concept, and its original structure could be adapted for other knotty subjects.

Aslanidi, M. ; Papadakis, I. ; Stefanidakis, M.: Name and title authorities in the music domain : alignment of UNIMARC authorities format with RDA.
In: Cataloging and classification quarterly. 56(2018) no.4, S.354-373.

Abstract: This article discusses and highlights alignment issues that arise between UNIMARC Authorities Format and Resource Description and Access (RDA) regarding the creation of name and title authorities for musical works and creators. More specifically, RDA, as an implementation of the FRAD model, is compared with the UNIMARC Authorities Format (Updates 2012 and 2016) in an effort to highlight various cases where the discovery of equivalent fields between the two standards is not obvious. The study is envisioned as a first step in an ongoing process of working with the UNIMARC community throughout RDA's advancement and progression regarding the entities [musical] Work and Names.

Mullin, C.A.: ¬An amicable divorce : programmatic derivation of faceted data from Library of Congress Subject Headings for music.
In: Cataloging and classification quarterly. 56(2018) no.7, S.607-627.

Abstract: Music catalogers have embraced in current cataloging the flexibility, intuitiveness, and expressivity afforded by the Library of Congress's new faceted vocabularies. In order to realize the full benefits to discovery these vocabularies offer, however, methods for programmatically assigning faceted terms retrospectively to existing metadata for music resources are required in order to mitigate the costs of manual enhancement of legacy data. This article describes efforts to repurpose existing Library of Congress Subject Headings as faceted data, taking advantage of recent developments in the MARC 21 formats. Limitations inherent to this process and ideas for future directions are described.

Hu, X. ; Lee, J.H. ; Bainbridge, D. ; Choi, K. ; Organisciak, P. ; Downie, J.S.: ¬The MIREX grand challenge : a framework of holistic user-experience evaluation in music information retrieval.
In: Journal of the Association for Information Science and Technology. 68(2017) no.1, S.97-112.

Abstract: Music Information Retrieval (MIR) evaluation has traditionally focused on system-centered approaches where components of MIR systems are evaluated against predefined data sets and golden answers (i.e., ground truth). There are two major limitations of such system-centered evaluation approaches: (a) The evaluation focuses on subtasks in music information retrieval, but not on entire systems and (b) users and their interactions with MIR systems are largely excluded. This article describes the first implementation of a holistic user-experience evaluation in MIR, the MIREX Grand Challenge, where complete MIR systems are evaluated, with user experience being the single overarching goal. It is the first time that complete MIR systems have been evaluated with end users in a realistic scenario. We present the design of the evaluation task, the evaluation criteria and a novel evaluation interface, and the data-collection platform. This is followed by an analysis of the results, reflection on the experience and lessons learned, and plans for future directions.

Hu, X. ; Choi, K. ; Downie, J.S.: ¬A framework for evaluating multimodal music mood classification.
In: Journal of the Association for Information Science and Technology. 68(2017) no.2, S.273-285.

Abstract: This research proposes a framework for music mood classification that uses multiple and complementary information sources, namely, music audio, lyric text, and social tags associated with music pieces. This article presents the framework and a thorough evaluation of each of its components. Experimental results on a large data set of 18 mood categories show that combining lyrics and audio significantly outperformed systems using audio-only features. Automatic feature selection techniques were further proved to have reduced feature space. In addition, the examination of learning curves shows that the hybrid systems using lyrics and audio needed fewer training samples and shorter audio clips to achieve the same or better classification accuracies than systems using lyrics or audio singularly. Last but not least, performance comparisons reveal the relative importance of audio and lyric features across mood categories.

Lee, J.H. ; Wishkoski, R. ; Aase, L. ; Meas, P. ; Hubbles, C.: Understanding users of cloud music services : selection factors, management and access behavior, and perceptions.
In: Journal of the Association for Information Science and Technology. 68(2017) no.5, S.1186-1200.

Abstract: Recent, rapid changes in technology have resulted in a proliferation of choices for music storage and access. Portable, web-enabled music devices are widespread, and listeners now enjoy a plethora of options regarding formats, devices, and access methods. Yet in this mobile music environment, listeners' access and management strategies for music collections are poorly understood, because behaviors surrounding the organization and retrieval of music collections have received little formal study. Our current research seeks to enrich our knowledge of people's music listening and collecting behavior through a series of systematic user studies. In this paper we present our findings from interviews involving 20 adult and 20 teen users of commercial cloud music services. Our results contribute to theoretical understandings of users' music information behavior in a time of upheaval in music usage patterns, and more generally, the purposes and meanings users ascribe to personal media collections in cloud-based systems. The findings suggest improvements to the future design of cloud-based music services, as well as to any information systems and services designed for personal media collections, benefiting both commercial entities and listeners.

Hu, X. ; Kando, N.: Task complexity and difficulty in music information retrieval.
In: Journal of the Association for Information Science and Technology. 68(2017) no.7, S.1711-1723.

Abstract: There has been little research on task complexity and difficulty in music information retrieval (MIR), whereas many studies in the text retrieval domain have found that task complexity and difficulty have significant effects on user effectiveness. This study aimed to bridge the gap by exploring i) the relationship between task complexity and difficulty; ii) factors affecting task difficulty; and iii) the relationship between task difficulty, task complexity, and user search behaviors in MIR. An empirical user experiment was conducted with 51 participants and a novel MIR system. The participants searched for 6 topics across 3 complexity levels. The results revealed that i) perceived task difficulty in music search is influenced by task complexity, user background, system affordances, and task uncertainty and enjoyability; and ii) perceived task difficulty in MIR is significantly correlated with effectiveness metrics such as the number of songs found, number of clicks, and task completion time. The findings have implications for the design of music search tasks (in research) or use cases (in system development) as well as future MIR systems that can detect task difficulty based on user effectiveness metrics.

Hu, X. ; Yang, Y.-H.: ¬The mood of Chinese Pop music : representation and recognition.
In: Journal of the Association for Information Science and Technology. 68(2017) no.8, S.1899-1910.

Abstract: Music mood recognition (MMR) has attracted much attention in music information retrieval research, yet there are few MMR studies that focus on non-Western music. In addition, little has been done on connecting the 2 most adopted music mood representation models: categorical and dimensional. To bridge these gaps, we constructed a new data set consisting of 818 Chinese Pop (C-Pop) songs, 3 complete sets of mood annotations in both representations, as well as audio features corresponding to 5 distinct categories of musical characteristics. The mood space of C-Pop songs was analyzed and compared to that of Western Pop songs. We also explored the relationship between categorical and dimensional annotations and the results revealed that one set of annotations could be reliably predicted by the other. Classification and regression experiments were conducted on the data set, providing benchmarks for future research on MMR of non-Western music. Based on these analyses, we reflect and discuss the implications of the findings to MMR research.

Lee, D.: Numbers, instruments and hands : the impact of faceted analytical theory on classifying music ensembles.
In: Knowledge organization. 44(2017) no.6, S.405-415.

Abstract: This article considers a particularly knotty aspect of classifying notated music: the classification of instrumental ensembles, where the term ensembles is defined as music written for multiple players with only one player per part. Facet analysis is used to examine this area of music classification and as the basis of a model for classifying ensembles. The conceptual analysis is aided by examples drawn from two classification schemes: British Catalogue of Music Classification (BCMC) and Flexible Classification. First, this exploration reveals that there are conceptually four sub-facets for classifying instrument ensembles, and that the omission of any of these sub-facets causes issues within classification schemes. Next, the different type of relationships between pairs of these sub-facets is delineated, including hierarchical and associative relationships. The classification of ensembles is depicted in a novel way, as a series of inter-connected relationships between sub-facets. Finally, the article ascertains exactly what is being counted, including introducing potential extra sets of sub-facets pertaining to performers and hands. So, facet analysis helps to create a model for classifying instrumental ensembles which provides a novel solution to this historically problematic area of music classification, as well as suggesting a potentially generalizable new way of thinking about complex relationships between sub-facets.

Abstract: In 2015, plans were put in place to relocate the entire compact disc collection of the Music and Media Center in the Arts and Humanities Library at Penn State's University Park campus, and to reclassify them from an accession number system to a more user-browsable one based on the Library of Congress Classification scheme. This article looks at the path that has being taken to reach this goal, and provides an initial assessment of the project at the halfway point.

Kishimoto, K. ; Snyder, T.: Popular Music in FRBR and RDA : toward user-friendly and cataloger-friendly identification of works.
In: Cataloging and classification quarterly. 54(2016) no.1, S.60-86.

Abstract: The gradual adoption since 2010 of the content standard Resource Description and Access, based on the conceptual model Functional Requirements for Bibliographic Records, has brought change to many areas of library cataloging, including popular music. In particular, the cataloging community has had to grapple with new practices in assigning access points for resources once considered simple, such as popular music albums containing songs written by people other than the featured recording artist. This article outlines some of the difficulties encountered and offers a principled approach to cataloging popular music that would reduce cataloger burden and reconcile catalog data with users' expectations.

Lee, J.H. ; Price, R.: User experience with commercial music services : an empirical exploration.
In: Journal of the Association for Information Science and Technology. 67(2016) no.4, S.800-811.

Abstract: The music information retrieval (MIR) community has long understood the role of evaluation as a critical component for successful information retrieval systems. Over the past several years, it has also become evident that user-centered evaluation based on realistic tasks is essential for creating systems that are commercially marketable. Although user-oriented research has been increasing, the MIR field is still lacking in holistic, user-centered approaches to evaluating music services beyond measuring the performance of search or classification algorithms. In light of this need, we conducted a user study exploring how users evaluate their overall experience with existing popular commercial music services, asking about their interactions with the system as well as situational and personal characteristics. In this paper, we present a qualitative heuristic evaluation of commercial music services based on Jakob Nielsen's 10 usability heuristics for user interface design, and also discuss 8 additional criteria that may be used for the holistic evaluation of user experience in MIR systems. Finally, we recommend areas of future user research raised by trends and patterns that surfaced from this user study.

Lee, J.H. ; Cho, H. ; Kim, Y.-S.: Users' music information needs and behaviors : design implications for music information retrieval systems.
In: Journal of the Association for Information Science and Technology. 67(2016) no.6, S.1301-1330.

Abstract: User studies in the music information retrieval (MIR) domain tend to be exploratory and qualitative in nature, involving a small number of users, which makes it difficult to derive broader implications for system design. In order to fill this gap, we conducted a large-scale user survey questioning various aspects of people's music information needs and behaviors. In particular, we investigated if general music users' needs and behaviors have significantly changed over time by comparing our current survey results with a similar survey conducted in 2004. In this paper, we present the key findings from the survey data and discuss 4 emergent themes-(a) the shift in access and use of personal music collections; (b) the growing need for tools to support collaborative music seeking, listening, and sharing; (c) the importance of "visual" music experiences; and (d) the need for ontologies for providing rich contextual information. We conclude by making specific recommendations for improving the design of MIR systems and services.

Lavranos, C. ; Kostagiolas, P. ; Korfiatis, N. ; Papadatos, J.: Information seeking for musical creativity : a systematic literature review.
In: Journal of the Association for Information Science and Technology. 67(2016) no.9, S.2105-2117.

Abstract: This paper aims to present a systematic literature review of research in music information seeking and its application to musical creativity and creative activities and in particular composition, performance and improvisation, and listening and analysis. A seed set of 901 articles published between 1973 and 2015 was evaluated and in total 65 studies were considered for further analyses. Data extraction and synthesis was performed through content analysis using the PRISMA method. Three thematic categories were identified in regard to music information needs: (a) those related to scholarly activities, (b) musically motivated, as well as (c) those which are related to socializing and communication. In addition, 3 categories of music information sources were connected to musical creativity: (i) those that are related to Internet and media technologies, (ii) those that are related to music libraries, organizations, and music stores, and (iii) those that are related to the subjects' social settings. The paper provides a systematic review, with the aim of showcasing the effect of modern information retrieval techniques in a creative and intensive area of information-dependent activity such as music making and consumption.

Wu, D. ; Shi, J.: Classical music recording ontology used in a library catalog.
In: Knowledge organization. 43(2016) no.6, S.416-430.

Abstract: In order to improve the organization of classical music information resources, we constructed a classical music recording ontology, on top of which we then designed an online classical music catalog. Our construction of the classical music recording ontology consisted of three steps: identifying the purpose, analyzing the ontology, and encoding the ontology. We identified the main classes and properties of the domain by investigating classical music recording resources and users' information needs. We implemented the ontology in the Web Ontology Language (OWL) using five steps: transforming the properties, encoding the transformed properties, defining ranges of the properties, constructing individuals, and standardizing the ontology. In constructing the online catalog, we first designed the structure and functions of the catalog based on investigations into users' information needs and information-seeking behaviors. Then we extracted classes and properties of the ontology using the Apache Jena application programming interface (API), and constructed a catalog in the Java environment. The catalog provides a hierarchical main page (built using the Functional Requirements for Bibliographic Records (FRBR) model), a classical music information network and integrated information service; this combination of features greatly eases the task of finding classical music recordings and more information about classical music.
