Abstract

The explosive growth of literature and data in the life sciences challenges researchers to keep track of current advancements in their disciplines. Novel approaches in the life science like the One Health paradigm require integrated methodologies in order to link and connect heterogeneous information from databases and literature resources. Current publications in the life sciences are increasingly characterized by the employment of trans-disciplinary methodologies comprising molecular and cell biology, genetics, genomic, epigenomic, transcriptional and proteomic high throughput technologies with data from humans, plants, and animals. The literature search engine LIVIVO empowers retrieval functionality by incorporating various literature resources from medicine, health, environment, agriculture and nutrition. LIVIVO is developed in-house by ZB MED - Information Centre for Life Sciences. It provides a user-friendly and usability-tested search interface with a corpus of 55 Million citations derived from 50 databases. Standardized application programming interfaces are available for data export and high throughput retrieval. The search functions allow for semantic retrieval with filtering options based on life science entities. The service oriented architecture of LIVIVO uses four different implementation layers to deliver search services. A Knowledge Environment is developed by ZB MED to deal with the heterogeneity of data as an integrative approach to model, store, and link semantic concepts within literature resources and databases. Future work will focus on the exploitation of life science ontologies and on the employment of NLP technologies in order to improve query expansion, filters in faceted search, and concept based relevancy rankings in LIVIVO.

Abstract

Europeana is an international trusted digital initiative providing access, from a single entry point, to prized collections from a number of European cultural institutions. Advanced Internet and digital technologies present new ways to connect with users; and there is a need continued evaluation of digital libraries. This paper reports on a task oriented, usability study exploring a number of aspects including user satisfaction specific to the Europeana Digital Library. Participants were students from Library Science and Information Systems department, who had some basic experience searching digital collections for information. Participants performed 13 tasks, and focused on the Hellenistic collection. Methodologically, the test was consisted of a list of tasks that among others aimed to assess user satisfaction and interest while performing them. The method applied was measuring Effectiveness, Efficiency, Learnability and Satisfaction. Despite the fact that it was not the first time that they came in contact with a digital library, several participants had difficulties while performing selected tasks, especially when they involved a variety of search types. In general, all of the participants seemed to comprehend how Europeana is organized, although the results also indicate that participants had feelings that expectations were not met when performing more complex tasks.
