There have been ample suggestions in the literature that terms added to documents from Flickr and Wikipedia can complement traditional methods of indexing and controlled vocabularies. At the same time, adding new metadata to existing metadata objects may not always add value to those objects. This research examines the potential added value of using(More)
The advent of big science has brought a dramatic increase in the amount of data generated as part of scientific investigation. The ability to capture and prepare such data for reuse has brought about an increased interest in data curation practices within scientific fields and venues such as national laboratories. This study employs semi-structured(More)

To be effective and at the same time sustainable, a community data curation model has to be aligned with the community's current work organization: practices and activities; divisions of labor; data and collaborative relationships; and the community's value structure, norms, and conventions for data, quality assessment, and data sharing. This poster(More)
To be effective and at the same time sustainable, a community data curation model needs to be aligned with the community’s current data practices, including research project activities, data types, and perceptions of data quality. Based on a survey of members of the Condensed Matter Physics (CMP) community gathered around the National High Magnetic Field(More)
With the increasing number of multilingual webpages on the Internet, cross-language information retrieval has become an important research issue. Using Activity Theory as a theoretical framework, this study employs semi-structured interviews with key informants who are frequent users of Chinese-English mixed language queries in web searching. The findings(More)
While there are increased efforts to extend existing controlled vocabularies through harvesting socially created image metadata from content creation communities (e.g., Flickr), questions remain about the quality and reuse value of this metadata. Data from a controlled experiment was used to examine relationships among categories of image tags, tag(More)
Accumulating evidence suggests that cancer-associated mesenchymal stem cells (MSC) contribute to the development and metastasis of hepatocellular carcinoma (HCC). Aberrant expression of long noncoding RNAs (lncRNA) has been associated with these processes but cellular mechanisms are obscure. In this study, we report that HCC-associated mesenchymal stem(More)
This paper analyzes the authority control practices in molecular biology using literature review and scenario analysis and makes a comparison with bibliographic authority control. The analysis indicates the absence of conceptual authority control model in molecular bioinformatics. In addition to traditional knowledge organization tools, authority control in(More)
Entity and instance determination, disambiguation, and referencing, referred to as authority control in libraries, are essential for scientific research. This study examines the authority control practices and issues in molecular biology using literature and scenario analyses. The analyses imply that the concept of authority control in molecular biology is(More)
