Abstract

This paper is a current assessment of the status of metadata creation and mapping between catalogerdefined field names and Dublin Core (DC) metadata elements across three digital image collections. The metadata elements that evince the most frequently inaccurate, inconsistent and incomplete DC metadata application are identified. As well, the most frequently occurring locally added metadata elements and associated pattern development are examined. For this, a randomly collected sample of 659 metadata item records from three digital image collections is analyzed. Implications and issues drawn from the evaluation of the current status of metadata creation and mapping are also discussed in relation to the issue of semantic interoperability of concept representation across digital image collections. The findings of the study suggest that conceptual ambiguities and semantic overlaps inherent among some DC metadata elements hinder semantic interoperability. The DC metadata scheme needs to be refined in order to disambiguate semantic relations of certain DC metadata elements that present semantic overlaps and conceptual ambiguities between element names and their corresponding definitions. The findings of the study also suggest that the development of mediation mechanisms such as concept networks that facilitate the metadata creation and mapping process are critically needed for enhancing metadata quality.

Abstract

Analysis of sociointerpersonal communication patterns among discourse participants is essential to understand the manifestation of and the interpersonal-communication features realized in online social interaction. The linguistic politeness theory provides an effective framework for such an analysis of sociointerpersonal communication features employed by online language users to maintain and enhance their public self-image, or face. The qualitative data analysis of this study, drawn from the real-time, online discussions of K-12 students, makes evident that interpersonal-communication features appear in the form of politeness tactics. The results of the study show that there is decreased use of deferential linguistic forms; on the contrary, a variety of verbal and nonverbal devices that denote positive politeness and bald-on-record (i.e., direct speech acts) frequently occur. The commonality of positive politeness and bald-on-record lies in the fact that both tactics are grounded in the nature of the close interpersonal relationships between participants. Such a communication pattern in the real-time, online discourse of K-12 students signifies that cognitive assessment of sociointerpersonal and contextual variables undertaken by speech participants underlies the realization of linguistic politeness. Employment of such politeness tactics indicates that effective and fully realized interpersonal communication plays a vital role in the development of online social interaction.
