Selection models in the music industry: How a prior independent experience may affect chart success

The is article analyses the two main approaches for artists’ selection in the recording industry: the direct model in which large major companies directly choose new artists from the supply market, and the agency model in which small independent labels realise the first choice and, subsequently, large organisations pick their new artists among those pre-selected by independents.An empirical analysis of chart sales reveals that artists selected through the agency model exhibit a longer presence on the chart due to repeated successes, while they are slower to reach heavy success once they have entered the chart. Conversely, the direct model leads to artists with a faster path to a strong success, but the same artists have a shorter presence on the chart due to the sporadic nature of their success. The profile of artists selected through these two models is also found to be different: big international soloist stars are more frequently selected through the direct model, while national bands are more frequently selected through the agency model.The insights suggest important implications for management in the cultural industries and especially in the recording industry.

从音乐文学的角度看古诗歌之兴衰

音乐魅力之大至于"夫乐者、乐也,人情之所必不免也".而诗歌如诗骚、如乐府、如唐诗、宋词、元曲作为音乐文学,在雅、清、燕、俗四代音乐的羽翼下,经三千年风雨盛传不衰,然至明清却"莫能继焉也"。终其要因,盖失文人、知识分子参与将明清俗乐与明清山歌(民歌)结合以明世。于是,诗歌至明清竟成遗韵绝响。故曰:"作诗苟不为声,虽意止而不能远。"     

论音乐小品

音乐小品是音乐文献中常见的一种作品类型,它大量出现在西方器乐音乐发展成熟以后的各个时期,其产生方式除了独立创作以外,有些则是从大型作品中节选而来。其较为突出的特点是短小精致、形式多样、通俗易懂,在音乐欣赏、音乐分析、音乐创作、演奏实践等多个方面发挥着奠基的重要作用。     

《中图法》第5版音乐类目 (J6) 刍议

《中图法》第5版音乐类目的修订基于增设类目、修订类名、增补修改注释、删除/停用类目等多个方面,但在音乐理论类目的细化、音乐作品类目内容与形式的统一等颇受音乐专业图书馆关注问题的修订方面,仍然存在不足或缺失.建议修订工作借鉴《中图法》第3版音乐类目表成功修订的经验,使《中图法》音乐类目表真正成为一部能够全面、正确反映音乐艺术科学特点、具有长期稳定性的统一的音乐文献分类标准.     

An unsupervised heuristic-based approach for bibliographic metadata deduplication

Digital libraries of scientific articles contain collections of digital objects that are usually described by bibliographic metadata records. These records can be acquired from different sources and be represented using several metadata standards. These metadata standards may be heterogeneous in both, content and structure. All of this implies that many records may be duplicated in the repository, thus affecting the quality of services, such as searching and browsing. In this article we present an approach that identifies duplicated bibliographic metadata records in an efficient and effective way. We propose similarity functions especially designed for the digital library domain and experimentally evaluate them. Our results show that the proposed functions improve the quality of metadata deduplication up to 188% compared to four different baselines. We also show that our approach achieves statistical equivalent results when compared to a state-of-the-art method for replica identification based on genetic programming, without the burden and cost of any training process.     

Collaborative management of business metadata

Legal provisions, cross-company data exchange and intra-company reporting or planning procedures require comprehensively, timely, unambiguously and understandably specified business objects (e.g. materials, customers, and suppliers). On the one hand, this business metadata has to cover miscellaneous regional peculiarities in order to enable business activities anywhere in the world. On the other hand, data structures need to be standardized throughout the entire company in order to be able to perform global spend analysis, for example. In addition, business objects should adapt to new market conditions or regulatory requirements as quickly and consistently as possible. Centrally organized corporate metadata managers (e.g. within a central IT department) are hardly able to meet all these demands. They should be supported by key users from several business divisions and regions, who contribute expert knowledge. However, despite the advantages regarding high metadata quality on a corporate level, a collaborative metadata management approach of this kind has to ensure low effort for knowledge contributors as in most cases these regional or divisional experts do not benefit from metadata quality themselves. Therefore, the paper at hand identifies requirements to be met by a business metadata repository, which is a tool that can effectively support collaborative management of business metadata. In addition, the paper presents the results of an evaluation of these requirements with business experts from various companies and of scenario tests with a wiki-based prototype at the company Bayer CropScience AG. The evaluation shows two things: First, collaboration is a success factor when it comes to establishing effective business metadata management and integrating metadata with enterprise systems, and second, semantic wikis are well suited to realizing business metadata repositories.

面向价值发现的学习资源描述方案：以LRMI元数据为例

随着信息技术和开放理念在资源领域的发展,如何构建良好资源生态,挖掘潜在价值成为资源建设与应用中一个研究热点。从强调“内容为王”到关注“情境为上帝”业已成为数字化资源的价值取向。在教育资源领域,应用元数据标记以实现资源在网络中的可发现性,追求“价值发现”已经成为教育资源库建设的新目标,期望从“人找资源”变为“资源随人”。LRMI元数据是面向价值发现的学习资源描述方案的典范,它对三大搜索引擎巨头Google、Yahoo、Bing 发起的Schema.org元数据词汇框架进行拓展,以提供符合教育特定需求的术语,同时增加资源在网络中的可发现性,优化资源的搜索结果。该文论述了当前学习资源价值的新诉求,以LRMI案例作为代表,总结了当前资源搜索的现实需求,分析了LRMI元数据的工作机制和当前学习资源库建设中的元数据描述方案。在LRMI 中,元数据实现了对资源的基本描述,而伴生数据则通过提供额外的情境信息,与元数据相互补充共同完成了对资源的完整表示。同时,连通利益相关者、学习资源、学习注册中心、情境信息构成一个良好生态系统,也为未来学习分析和开放教育资源发展提供了潜在的解决方案。
