1Ng, K.B. ; Kantor, P.B. ; Strzalkowski, T. ; Wacholder, N. ; Tang, R. ; Bai, B. ; Rittman, ; Song, P. ; Sun, Y.: Automated judgment of document qualities.
In: Journal of the American Society for Information Science and Technology. 57(2006) no.9, S.1155-1164.
Abstract: The authors report on a series of experiments to automate the assessment of document qualities such as depth and objectivity. The primary purpose is to develop a quality-sensitive functionality, orthogonal to relevance, to select documents for an interactive question-answering system. The study consisted of two stages. In the classifier construction stage, nine document qualities deemed important by information professionals were identified and classifiers were developed to predict their values. In the confirmative evaluation stage, the performance of the developed methods was checked using a different document collection. The quality prediction methods worked well in the second stage. The results strongly suggest that the best way to predict document qualities automatically is to construct classifiers on a person-by-person basis.
2Ng, K.B.: ¬The applicability of universal pragmatics in information retrieval interaction : a pilot study.
In: Information processing and management. 38(2002) no.2, S.237-248.
Abstract: This article discusses the possibility and usefulness of applying Habermas' universal pragmatics to analyze information retrieval interaction. The first part of the article is theoretical argumentation. It examines the current common schemes of studies of human computer interaction (HCI), inspects their appropriateness and limitations, argues for a pragmatic perspective, and elaborates some of Habermas' idea of universal pragmatics. The second part is a case study. It reports an investigation of the initiation and development of verification of validity claims in HCI from the universal pragmatics perspective. It describes some patterns in which a user deals with what may be considered as invalid claims of an IR system outputs. A typical sequence consists of the following pattern: (1) user invokes a simple request; (2) system replies with a questionable answer; leading to (3) user tries to verify the validity claims of truth, truthfulness, and/or rightness of the system output; and (4) when the available interaction channels cannot support the validation, the interaction becomes a non-communicative process which discourages further interaction.
3Ng, K.B.: Toward a theoretical framework for understanding the relationship between situated action and planned action models of behavior in information retrieval contexts : contributions from phenomenology.
In: Information processing and management. 38(2002) no.5, S.613-626.
Abstract: In human-computer interaction (HCI), a successful interaction sequence can take its own momentum and drift away from what the user has originally planned. However, this does not mean that planned actions play no important role in the overall performance. In this paper, the author tries to construct a line of argument to demonstrate that it is impossible to consider an action without an a priori plan, even according to the phenomenological position taken for granted by the situated action theory. Based on the phenomenological analysis of problematic situations and typification the author argues that, just like "situated-ness", "planned-ness" of an action should also be understood in the context of the situation. Successful plan can be developed and executed for familiar context. The first part of the paper treats information seeking behavior as a special type of social action and applies Alfred Schutz's phenomenology of sociology to understand the importance and necessity of plan. The second part reports results of a quasi-experiment focusing on plan deviation within an information seeking context. It was found that when the searcher's situation changed from problematic to non-problematic, the degree of plan deviation decreased significantly. These results support the argument proposed in the first part of the paper.

4Burnett, K. ; Ng, K.B. ; Park, S.: ¬A comparison of the two traditions of metadata development.
In: Journal of the American Society for Information Science. 50(1999) no.13, S.1209-1217.
Abstract: Metadata has taken on a more significant role than ever before in the emerging digital library context because the effective organization of networked information clearly depends on the effective management and organization of metadata. The issue of metadata has been approached variously by different intellectual communities. The 2 main approaches may be characterized as: (1) the bibliographic control approach (origins and major proponents in library science); and (2) data management approach (origins and major proponents in computer science). This article examines the different conceptual foundations and orientations of the 2 major approaches contributing to the metadata discussion. An examination of the on-going efforts to establish metadata standards, and comparison of different metadata formats, supports a proposal for an integrated concept of metadata to facilitate the merging of the 2 approaches
