  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.

  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.

  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.

  Madalli, D.P. ; Balaji, B.P. ; Sarangi, A.K.: Faceted ontological representation for a music domain : an editorial.
  In: Knowledge organization. 42(2015) no.1, S.8-24.
  
  Abstract: This paper proposes an analysis of faceted theory and of various knowledge organization approaches. Building upon the faceted theory of S.R. Ranganathan (1967), the paper intends to address the faceted classification approach applied to build domain ontologies. Based on this perspective, an ontology of a music domain has been analyzed that would serve as a case study. As classificatory ontologies are employed to represent the relationships of entities and objects on the web, the faceted approach is deemed as an effective means to help organize web content. While different knowledge organization systems are being employed to address the cluttered Web in different contexts and with various degrees of effectiveness, faceted ontologies have an enormous potential for addressing this issue by performing.

  Kostagiolas, P.A. ; Lavranos, C. ; Korfiatis, N. ; Papadatos, J. ; Papavlasopoulos, S.: Music, musicians and information seeking behaviour : a case study on a community concert band.
  In: Journal of documentation. 71(2015) no.1, S.3-24.
  
  Abstract: Purpose - The purpose of this paper is to examine information seeking behaviour targeted to music information seeking by amateur musicians, accompanied with empirical evidence from a survey on a community concert band. While several studies in the literature have examined information seeking in the context of hedonic motives (e.g. entertainment oriented), music information can also be used for utilitarian purposes by providing amateur musicians the necessary tools to improve their skill and become better in their practice. Design/methodology/approach - A review of the literature on music information seeking and an empirical study on members of an amateur concert band are presented. The theoretical construct of the survey is informed by Wilsons' macro model of information seeking behaviour. This is employed in order to understand information motives and needs, as well as obstacles in information seeking of musicians. Findings - Musicians seek information not only for entertainment but for educational purposes as well as for the acquisition of certain music works. The use of the internet for information seeking as well as the gradual adoption of online social networks has provided access to new musical resources within the digital music networks. Originality/value - A person-centred approach for information seeking behaviour is studied and adapted for musicians. The survey provides new information behaviour results for designers of music information spaces which in turn are creating a new model of the relationship between music and society.

  Gentili-Tedeschi, M.: Music presentation format : toward a cataloging babel?.
  In: Cataloging and classification quarterly. 53(2015) no.3/4, S.399-413.
  
  Abstract: This case study on cataloging notated music focuses on music presentation format, and the use of controlled vocabularies in a multilingual context, when concepts do not have corresponding terms in one or more languages, and when common language terms are mixed with technical terms in a specialized context. Issues concern the terminological correspondence among different languages, and the consequent risks if only one language is taken into account or the meaning of one word is arbitrarily altered; English linguistic pragmatism may lead to wrong conceptual results when it points directly to the result of a process, while other languages focus on the process needed to obtain that result. Considerations on the use of codes in MARC formats and on how music presentation is treated in Functional Requirements for Bibliographic Records (FRBR) are included, and numerous illustrated examples, understandable even by non-music experts, support the article.
