Digital repository managers rely on usage metrics such as the number of downloads to demonstrate research visibility and impacts of the repositories. Increasingly, they find that current tools such as spreadsheets and charts are ineffective for revealing important elements of usage, including reader locations, and for attracting the targeted audiences....
INTRODUCTION: Academic libraries have experimented with a variety of services to encourage article deposit to institutional repositories, with varying degrees of success. Universities now face the challenge of meeting federal agency public access requirements. Following the White House Office of Science Technology and Policy public access directive in 2013, Oregon...
Web Information Discovery Tool (WIDIT) Laboratory at the Indiana University School of Library, whose basic approach to combine multiple methods as well as to leverage multiple sources of evidence, participated in 2005 Text Retrieval Conference’s Hard track (HARD-2005) to investigate methods of effectively dealing with HARD topics by exploring a...
The National Institutes of Health (NIH) Public Access Policy that began in 2008 requires that final peer-reviewed journal manuscripts sponsored by the agency are freely available in PubMed Central. NIH requires that researchers who apply for grants must include a PMC reference number (PMCID) when citing their papers that were...
Exposing research data from traditional repository systems such as DSpace in Linked Data has numerous benefits such as increasing visibility, prompting open access, and interlinking datasets with elements such as authors. For a successful implementation, it is crucial to preserve object structure (e.g., hierarchical and related) in Linked Data in...
In this paper, we describe a fusion approach to finding opinionated blog postings. Our approach to opinion blog retrieval consisted of first applying traditional IR methods to retrieve on-topic blogs and then boosting the ranks of opinionated blogs based on combined opinion scores generated by multiple assessment methods. Our opinion...
In TREC-2007, Indiana University‟s WIDIT Lab1 participated in the Blog track‟s opinion task and the polarity subtask. For the opinion task, whose goal is to "uncover the public sentiment towards a given entity/target", we focused on combining multiple sources of evidence to detect opinionated blog postings. Since detecting opinionated blogs...
Many institutions have open access (OA) policies that require faculty members to deposit their articles in an institutional repository (IR). A clear motivation is that a policy will result in increased self-archiving. The purpose of this longitudinal study is to compare the impact of a campus-wide OA policy and mediated...

Despite limited success, today’s information retrieval (IR) systems are not intelligent and reliable. IR systems return poor search results when users formulate their information needs into incomplete or ambiguous queries (i.e., weak queries). Therefore, one of the main challenges in modern IR research is to provide consistent results across all...
