Assessing Descriptive Substance in Free-Text Collection-Level Metadata

Collection-level metadata has the potential to provide important information about the features and purpose of individual collections. This paper reports on a content analysis of collection records in an aggregation of cultural heritage collections. The findings show that the free-text Description field often provides more accurate and complete representation of subjects and object types than the specified fields. Properties such as importance, uniqueness, comprehensiveness, provenance, and creator are articulated, as well as other vital contextual information about the intentions of a collector and the value of a collection, as a whole, for scholarly users. The results demonstrate that the semantically rich free-text Description field is essential to understanding the context of collections in large aggregations and can serve as a source of data for enhancing and customizing controlled vocabulariesIMLS NLG Research and Demonstration grant LG-06-07-0020-07published or submitted for publicationis peer reviewe

Dublin Core Metadata Harvested Through OAI-PMH

The introduction in 2001 of the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) increased interest in and awareness of metadata quality issues relevant to digital library interoperability and the use of harvested metadata to build "union catalogs" of digital information resources. Practitioners have offered wide-ranging advice to metadata authors and have suggested metrics useful for measuring the quality of shareable metadata. Is there evidence of changes in metadata practice in response to such advice and/or as a result of an increased awareness of the importance of metadata interoperability? This paper looks at metadata records created over a six-year period that have been harvested by the University of Illinois at Urbana Champaign, and reports on quantitative and qualitative analyses of changes observed over time in shareable metadata quality.IMLS National Leadership Grant LG-02-02-0281published or submitted for publicationis peer reviewe

Testing Resource Description and Access (RDA) with Dublin Core

Resource Description and Access (RDA) is a new standard for describing all types of resources. Columbia University, the University of Chicago, and the University of Illinois at Urbana-Champaign evaluated the guidelines by means of the Dublin Core element set during the U.S. National Libraries RDA Test, held from October to December 2010. This paper speaks to the issues which emerged during the test and what each institution did to address them. Test set-ups employed, and tools used, as well as a selection of problems encountered are described in the following summation of findings

Metadata Maker

Metadata Maker was developed to improve the productivity of cataloging and metadata workflows, allowing anyone to create metadata in various formats, regardless of their familiarity and experience with metadata standards.Ope

Metadata Maker for Digital Publication

As many academic and research libraries are considering or have already started developing digital scholarly publishing programs, these programs need to find a proper way to create metadata for access to these new publications. However, metadata for digital publications has its own challenges in two areas: metadata schemas and controlled vocabularies. For example, metadata for digital publications requires a specific set of metadata elements that are different from traditional print resources. Also, in order for scholarly digital publications to be managed and discovered with other books that are published by established publishing houses, the application of subject headings should be described using controlled vocabularies that are standard in the publishing community, such as BISAC (https://www.bisg.org/bisac/bisac-subject-codes), and represented in the ONIX format in addition to MARC and MODS, metadata schemas used in the library domain. Furthermore, as libraries are moving forward towards the semantic web and linked data, metadata should also include linked data components that would increase the discoverability of resources on the web. This poster introduces a metadata creation tool for electronic resources including digital publications, Metadata Maker for E-books (http://quest.library.illinois.edu/marcmaker/ebooks/) created to support these needs. The tool utilizes two subject headings: FAST for traditional library description, and BISAC subject codes and terms for publishers. Metadata Maker provides users, who may have minimal metadata knowledge and experience, a tool to create metadata in five different formats: MARC, MARCXML, MODS, schema.org embedded HTML, and ONIX for Books, depending on their needs.Ope

Disambiguating Descriptions: Mapping Digital Special Collections Metadata into Linked Open Data Formats

In this poster we describe the Linked Open Data (LOD) for Digital Special Collections project at the University of Illinois at Urbana-Champaign and describe some of the particular challenges that legacy metadata poses for representation in LOD formats. LOD formats are primarily based on the World Wide Web Consortium’s Resource Description Framework standard which demands both that entities be named by opaque universal identifiers whenever possible but also that metadata descriptions for entities be as unambiguous as possible. The challenges for disambiguating those descriptions are illustrated through examples drawn from digital special collections based at four different digital librariesOpe

Aligning author-supplied keywords for ETDs with domain-specific controlled vocabularies

Subject access can provide essential points of access for users to find, identify, select, and obtain various resources available in libraries. Subject access is not always available, however, due to the increasing amount of metadata created by non-catalogers (including author-supplied metadata), changes in libraries’ discovery services, and a lack of best practices for aligning non-controlled vocabularies to authorized subject headings. This paper addresses the issue of author-supplied metadata, specifically how to align keywords submitted by authors of electronic theses and dissertations (ETDs) with Library of Congress Subject Headings (LCSH) and discipline-specific taxonomies by analyzing 32,696 keywords from 5,365 master's theses and doctoral dissertations submitted to the University of Illinois at Urbana-Champaign's institutional repository between 2010 and 2014. This paper shares findings from the data analysis, including that matching rates vary depending on college, with newer or rapidly-developing fields (such as the School of Molecular and Cellular Biology) having lower matching rates than traditional, well-established fields of study (such as the College of Agriculture, Consumer, and Environmental Sciences), and recommends that when keyword reconciliation is performed, it should be done with more than one authority in tandem for the best results; when the LCSH and discipline-specific controlled vocabularies were combined, matching results were slightly or moderately increased.Ope

Exploring the Benefits for Users of Linked Open Data for Digitized Special Collections, White paper #1: Transforming special collections metadata into linked open data: mappings, entity reconciliation, workflows implemented & lessons learned

Transforming and migrating legacy metadata for special collections to a linked data compatible ontology requires metadata remediation, enhancement, and mapping. Entity reconciliation (adding the links) is a critical component as well. The first part of this white paper summarizes the mappings and workflows developed for our three digital special collections (Motley Collection of Theatre and Costume Design, Portraits of Actors, and the Kolb-Proust Archive Research), the challenges encountered, and solutions identified for these challenges. The second part of this white paper describes entity reconciliation approaches used to discover links to more information about the entities mentioned in the metadata.Andrew W.

Expression and Mutational Analysis of c-kit in Ovarian Surface Epithelial Tumors

Coexpression of Kit ligand and c-kit has been reported in some gynecologic tumors. To determine whether imatinib mesylate is useful in ovarian epithelial tumors, we performed immunohistochemical and mutational analysis. The cases consisted of 33 cases, which included 13 serous cystadenocarcinomas, 1 borderline serous tumor, 8 mucinous cystadenocarcinomas, 6 borderline mucinous tumors and 5 clear cell carcinomas. Five cases of serous cystadenoma and 5 cases of mucinous cystadenoma were also included. In the immunohistochemical study, 3 cases (3/6, 50%) of borderline mucinous cystic tumor and two cases (2/8, 25%) of mucinous cystadenocarcinoma show positive staining for KIT protein. Only one case (1/13, 7.7%) of serous cystadenocarcinoma had positive staining. On mutational analysis, no mutation was identified at exon 11. However, two cases of borderline mucinous tumors and one case of mucinous cystadenocarcinoma had mutations at exon 17. In these cases, the immunohistochemistry also shows focal positive staining at epithelial component. Although, KIT protein expression showed higher incidence in mucinous tumors than serous tumors, they lack KIT-activating mutations in exon 11. Thus, ovarian surface epithelial tumors are unlikely to respond to imatinib mesylate

Phelan-McDermid syndrome presenting with developmental delays and facial dysmorphisms

Phelan-McDermid syndrome is a rare genetic disorder caused by the terminal or interstitial deletion of the chromosome 22q13.3. Patients with this syndrome usually have global developmental delay, hypotonia, and speech delays. Several putative genes such as the SHANK3, RAB, RABL2B, and IB2 are responsible for the neurological features. This study describes the clinical features and outcomes of Korean patients with Phelan-McDermid syndrome. Two patients showing global developmental delay, hypotonia, and speech delay were diagnosed with Phelan-McDermid syndrome via chromosome analysis, fluorescent in situ hybridization, and multiplex ligation-dependent probe amplification analysis. Brain magnetic resonance imaging of Patients 1 and 2 showed delayed myelination and severe communicating hydrocephalus, respectively. Electroencephalography in patient 2 showed high amplitude spike discharges from the left frontotemporoparietal area, but neither patient developed seizures. Kidney ultrasonography of both the patients revealed multicystic kidney disease and pelviectasis, respectively. Patient 2 experienced recurrent respiratory infections, and chest computed tomography findings demonstrated laryngotracheomalacia and bronchial narrowing. He subsequently died because of heart failure after a ventriculoperitoneal shunt operation at 5 months of age. Patient 1, who is currently 20 months old, has been undergoing rehabilitation therapy. However, global developmental delay was noted, as determines using the Korean Infant and Child Development test, the Denver developmental test, and the Bayley developmental test. This report describes the clinical features, outcomes, and molecular genetic characteristics of two Korean patients with Phelan-McDermid syndrome
