Unlocking Hierarchical Structural Semantics in HathiTrust Digital Library Historical Medical Book Indexes for Information Retrieval: Two Preliminary Investigations
Direct linkDirect link
Huapu Liu – ProQuest LLC, 2024
This two-part dissertation centers on a re-examination of the role of book indexes in information retrieval research on full-text digital book collections in digital libraries. Early research focused on information retrieval and book indexes (in addition to other parts of books) in the 2000s when the Google Books corpus was first released to the…

Subject and Citation Indexing. Part I: The Clustering Structure of Composite Representations in the Cystic Fibrosis Document Collection. Part II: The Optimal, Cluster-Based Retrieval Performance of Composite Representations.
Peer reviewed Peer reviewed
Shaw, W. M., Jr. – Journal of the American Society for Information Science, 1991
Two articles discuss the clustering of composite representations in the Cystic Fibrosis Document Collection from the National Library of Medicine's MEDLINE file. Clustering is evaluated as a function of the exhaustivity of composite representations based on Medical Subject Headings (MeSH) and citation indexes, and evaluation of retrieval…

Topological Indices of Textual Identity Networks.
Leazer, Gregory H.; Furner, Jonathan – Proceedings of the ASIS Annual Meeting, 1999
Reports on a continuing investigation of intertextual networks. Describes how intertextual networks can be modeled as directed graphs and extends this to matrix representations. Discusses topological index values of these networks and speculates how topological index values might be used in the estimation of retrieval values in information…

Subject Indexing and Citation Indexing--Part I: Clustering Structure in the Cystic Fibrosis Document Collection [and] Part II: An Evaluation and Comparison.
Peer reviewed Peer reviewed
Shaw, W. M., Jr. – Information Processing and Management, 1990
These two articles discuss clustering structure in the Cystic Fibrosis Document Collection, which is derived from the National Library of Medicine's MEDLINE file. The exhaustivity of four subject representations and two citation representations is examined, and descriptor-weight thresholds and similarity thresholds are used to compute…

Evaluation of the MEDLARS Demand Search Service.
Lancaster, F.W. – 1968
A detailed analysis was made by the National Library of Medicine of the performance of the Medical Literature and Analysis System (MEDLARS) in relation to 300 actual "demand search" requests made to the systems in 1966 and 1967. The objectives of the study were : (1) to study the demand search requirements of MEDLARS users, (2) to…
