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...
Web Information Discovery Tool (WIDIT) Laboratory at the Indiana University School of Library and Information Science participated in the HARD, Robust, and SPAM tracks in TREC- 2005. The basic approach of WIDIT is to combine multiple methods as well as to leverage multiple sources of evidence. Our main strategies for...
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...
Web Information Discovery Integrated Tool (WIDIT) Laboratory at the Indiana University School of Library and Information Science participated in the Blog track’s opinion task in TREC- 2006. The goal of opinion task is to "uncover the public sentiment towards a given entity/target", which involves not only retrieving topically relevant 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...
Academic libraries that offer digital asset management systems (DAMS) and services such as an institutional repository, data curation services, and digitization of historic documents face the need to assess and refine services. This need can be most apparent when considering changes to DAMS infrastructure. The proposed panel presents the experiences...
In this paper, we describe a fusion approach to finding opinion about a given target in blog postings. We tackled the opinion blog retrieval task by breaking it down to two sequential subtasks: on- topic retrieval followed by opinion classification. Our opinion retrieval approach was to first apply traditional IR...
