Wickett, Karen M. and Renear, Allen H. (2012): The logical form of the proposition expressed by a metadata record. In: JCDL12 Proceedings of the 2012 Joint International Conference on Digital Libraries 2012. pp. 413-414.

Metadata records are a ubiquitous and foundational feature of contemporary information systems. However, while their simple surface structure may lead us to think that the semantics of a metadata record is unproblematic and easily discerned, our analysis of an example record suggests otherwise. We show three possibilities for the logical form of the proposition expressed by a metadata record. All three are substantially different in the first order constructs utilized, and no two can be recognized as equivalent for the purposes of information organization. The semantics of the common metadata record is elusive. The main source of this problem appears to be the identifier attribute. Although identifier attributes have the syntactic appearance of any other attribute in the metadata vocabulary, this uniformity conceals their potential for assuming a distinctive semantic role, and one which appears to cross the traditional object language / metalanguage boundary, suggesting that translation of colloquial metadata records into logic-based knowledge representations does not take place entirely at a first-order level.

Wickett, Karen M., Urban, Richard J. and Renear, Allen H. (2012): Towards a logical form for descriptive metadata. In: Proceedings of the 2012 iConference 2012. pp. 574-575.

Open linked data and semantic technologies promise support for information integration and inferencing. But taking advantage of this support often requires that the information carried by ordinary "colloquial" metadata records be made explicit and computationally available. Given the structured nature of most metadata records this looks easy to do; and conversion from metadata records to computer processable knowledge representation languages such as RDF is now commonplace. Nevertheless a precise formal characterization of the semantics of common colloquial metadata records is more involved than appearances would suggest. We explore two approaches to formalization and discuss some issues related to the nature of identifier elements in colloquial metadata records and the use of individual constants in knowledge representation.

Wickett, Karen M. (2011): Expressiveness requirements for reasoning about collection/item metadata relationships. In: Proceedings of the 2011 iConference 2011. pp. 796-797.

Logical relationships between descriptive metadata statements can reveal important semantic features and support useful tools. This poster examines the logical features of a framework for collection/item metadata relationships, as part of placing the framework on a systematic logical foundation and assessing the logical requirements of systems to encode and reason over metadata relationships. The kind of logical constructs required to reason with these relationships will have an impact on the development of systems that take advantage of collection and item descriptions together.

Renear, Allen H., Wickett, Karen M., Urban, Richard J. and Dubin, David (2008): The return of the trivial: problems formalizing collection/item metadata relationships. In: JCDL08 Proceedings of the 8th ACM/IEEE-CS Joint Conference on Digital Libraries 2008. p. 464.

Formalizing collection/item metadata relationships encounters the problem of trivial satisfaction. We offer a solution related to current work in IR and ontology evaluation.
