Automatic Language Identification for Metadata Records: Measuring the Effectiveness of Various Approaches

Description: Automatic language identification has been applied to short texts such as queries in information retrieval, but it has not yet been applied to metadata records. Applying this technology to metadata records, particularly their title elements, would enable creators of metadata records to obtain a value for the language element, which is often left blank due to a lack of linguistic expertise. It would also enable the addition of the language value to existing metadata records that currently lack a language value. Titles lend themselves to the problem of language identification mainly due to their shortness, a factor which increases the difficulty of accurately identifying a language. This study implemented four proven approaches to language identification as well as one open-source approach on a collection of multilingual titles of books and movies. Of the five approaches considered, a reduced N-gram frequency profile and distance measure approach outperformed all others, accurately identifying over 83% of all titles in the collection. Future plans are to offer this technology to curators of digital collections for use.

Convenience to the Cataloger or Convenience to the User?: An Exploratory Study of Catalogers’ Judgment

Description: This mixed-method study explored cataloger’s judgment through the presence of text as entered by catalogers for the 11 electronic resource items during the National Libraries test for Resource Description and Access (RDA). Although the literature discusses cataloger’s judgment and suggests that cataloging practice based on new cataloging code RDA will more heavily rely on cataloger’s judgment, the topic of cataloger’s judgment in RDA cataloging was not formally studied. The purpose of this study was to study the differences and similarities in the MARC records created as a part of the RDA National Test and to determine if the theory of bounded rationality could explain cataloger’s judgment based on the constructs of cognitive and temporal limits. This goal was addressed through a content analysis of the MARC records and various statistical tests (Pearson’s Chi-square, Fisher’s Exact, and Cramer’s V). Analysis of 217 MARC records was performed on seven elements of the bibliographic record. This study found that there were both similarities and differences among the various groups of participants, and there are indications that both support and refute the assertion that catalogers make decisions based on the constructs of time and cognitive ability. Future research is needed to be able to determine if bounded rationality is able to explain cataloger’s judgment; however, there are indicators that both support and refute this assertion. The findings from this research have implications for the cataloging community through the provision of training opportunities for catalogers, evaluating workflows, ensuring the proper indexing of bibliographic records for discovery, and recommended edits to RDA.

Patient Family and Hospital Staff Information Needs at a Pediatric Hospital: an Analysis of Information Requests Received by the Family Resource Libraries

Description: This research explored the information needs of patient families and hospital staff at a pediatric hospital system in Dallas, Texas. Library statistics recorded in four hospital libraries from 2011 - 2013 were used to analyze the information requests from patient families and hospital staff. Crosstabulations revealed the extent to which patient families and hospital staff used the libraries to satisfy their information needs. The data showed that patient families used the libraries very differently than hospital staff. Chi-square tests for independence were performed to identify the relationships between the Classification (Patient Family, Hospital Staff) and two descriptors of information needs (Request Type, Resources Used). There were a total of 1,406 information requests analyzed. The data showed that patient families and hospital staff information requests differed greatly in the number of information requests, the type of information requested, the resources used and the time the library staff spent on the requests. Chi-square analyses revealed relationships statistically significant at the p < .05 level; however, the strength of the relationships varied.

Readiness of Indonesian Academic Libraries for Open Access and Open Access Repositories Implementation: a Study on Indonesian Open Access Repositories Registered in OpenDOAR

Description: Scholarly and scientific communication has a long history, while the Open Access (OA) movement began to take part in this communication with the emergence of Internet in the late 1960s and the web that emerged in mid-1990s. OA is beneficial for sharing knowledge because the OA movement demands scholarly literature freely available on the internet and it is free of most licensing restriction copyright. OA will close the barrier of access to knowledge. The OA movement in Indonesia may be considered slow. So far, only 33 academic libraries have registered their repositories with OpenDOAR, which is still small compared to the total number of HE institutions in Indonesia. Those 33 OARs vary in the stages of development. Some have already had large size of contents, while others are still developing. Using Weiner’s theory of organizational readiness for change, this mixed method investigates the readiness of academic librarians for Open Access Repository implementation. The results show that academic librarians in Indonesia are somewhat familiar with OA and OAR. However, their understanding of OA is still limited to the technical nature of it. They also know the benefits of OA in relation to scholarly communication and are ready to implement OAR, but the implementation was mostly based on the goal of achieving a specific rank in the world-class university ranking and Webometrics. They implemented Open Access Repositories with limited technological infrastructure, skills, and limited knowledge of OA.
