Purpose

This study seeks to understand the current state of the development of linked open data (LOD) bibliographic portals to discuss their functionalities, contributions, value-adds and user experience.

Design/methodology/approach

A set of evaluative aspects grouped into three analysis dimensions was established: collections, tools—technologies and standards used—and web user interface. As the object of the study, four projects of diverse nature and volume were selected to help provide a better understanding of the trends in the solutions provided for the end user when accessing linked data collections.

Findings

Publishing LOD through visual interfaces maximises information enrichment, contextualisation and discovery, in addition to improving user experience, because of both increased navigation capabilities and interrelationships between data. These more flexible environments have metamorphosised the visualisation of bibliographic information. However, aspects that needed improvement were observed, primarily relating to (1) a more intuitive interaction, (2) possibilities of greater personalisation, (3) enhanced communication with the user to favour user engagement and (4) experimental spaces of data reuse.

Research limitations/implications

Further quantitative and qualitative studies should be conducted to improve these portals, assess their adaptation to the behaviour of the user and their influence on the use of library collections.

Originality/value

This article investigates the potential of semantic technologies in bibliographic data portals, proposes a methodological model for their evaluation and advances conclusions about the usability and user experience that these platforms provide, compared to classic catalogues.

链接的开放数据门户：语义目录中的功能和用户体验

目的

本研究旨在了解链接开放数据 (LOD) 书目门户的发展现状，以讨论其功能、贡献、增值和用户体验。

设计/方法/方法

建立了一组分为三个分析维度的评估方面：集合、工具——所使用的技术和标准——以及网络用户界面。作为研究的对象，选择了四个性质和数量各不相同的项目，以帮助更好地了解在访问链接数据集合时为最终用户提供的解决方案的趋势。

发现

由于导航功能和数据之间的相互关系增加，除了改善用户体验之外，通过可视化界面发布 LOD 还可以最大限度地丰富信息、上下文化和发现。这些更灵活的环境已经改变了书目信息的可视化。然而，观察到需要改进的方面，主要涉及 (1) 更直观的交互，(2) 更大个性化的可能性，(3) 加强与用户的沟通以促进用户参与以及 (4) 数据重用的实验空间。

研究限制/影响

应该进行进一步的定量和定性研究以改进这些门户，评估它们对用户行为的适应性及其对图书馆馆藏使用的影响。

原创性/价值

本文研究了书目数据门户中语义技术的潜力，提出了一种评估方法模型，并提出了与经典目录相比这些平台提供的可用性和用户体验的结论。
