  Cho, H. ; Disher, T. ; Lee, W.-C. ; Keating, S.A. ; Lee, J.H.: Facet analysis of anime genres : the challenges of defining genre information for popular cultural objects.
  In: Knowledge organization. 47(2020) no.1, S.13-30.
  
  Abstract: Anime, as a growing form of multimedia, needs a better and more thorough organization for its myriad unique terminologies. Existing studies show patrons' desire to search and get recommendations for anime. However, due to inadequate indexing and often confusing or inaccurate usage of terms, searching and acquiring recommendations remain challenging. Our research seeks to close the gap and make discovery and recommendations more viable. In this study, we conducted a facet analysis of anime genre terms that are currently used in thirty-six anime-related English-language databases and websites. Using a card sorting method with an inductive approach to the 1,597 terms collected, we identified and defined nine facets and 153 foci terms that describe different genres of anime. Identified terms can be implemented within different organizational systems including library catalogs, recommendation systems, and online databases to improve genre definitions and search experiences.

  Lee, W.-C.: Conflicts of semantic warrants in cataloging practices.
  In: http://www.iskocus.org/NASKO2017papers/NASKO2017_paper_25.pdf [NASKO 2017, June 15-16, 2017, Champaign, IL, USA].
  
  Abstract: This study presents preliminary themes surfaced from an ongoing ethnographic study. The research question is: how and where do cultures influence the cataloging practices of using U.S. standards to catalog Chinese materials? The author applies warrant as a lens for evaluating knowledge representation systems, and extends the application from examining classificatory decisions to cataloging decisions. Semantic warrant as a conceptual tool allows us to recognize and name the various rationales behind cataloging decisions, grants us explanatory power, and the language to "visualize" and reflect on the conflicting priorities in cataloging practices. Through participatory observation, the author recorded the cataloging practices of two Chinese catalogers working on the same cataloging project. One of the catalogers is U.S. trained, and another cataloger is a professor of Library and Information Science from China, who is also a subject expert and a cataloger of Chinese special collections. The study shows how the catalogers describe Chinese special collections using many U.S. cataloging and classification standards but from different approaches. The author presents particular cases derived from the fieldwork, with an emphasis on the many layers presented by cultures, principles, standards, and practices of different scope, each of which may represent conflicting warrants. From this, it is made clear that the conflicts of warrants influence cataloging practice. We may view the conflicting warrants as an interpretation of the tension between different semantic warrants and the globalization and localization of cataloging standards.

  Lee, W.-C.: Culture and classification : an introduction to thinking about ethical issues of adopting global classification standards to local environments.
  In: Knowledge organization. 42(2015) no.5, S.302-307.
  
  Abstract: Ethical issues arise from adapting standardized classification schemes to local environments. Research affirms mutual influences between culture and classification schemes, however, there are various conceptions of culture. Before diving deeper into discussions on designing a culturally sensitive model of classification and providing ethical information services, it is critical to clarify how culture is defined in the literature. In order to gain a deeper understanding of how scholars view the concept of culture, we review, compare, and aggregate discussions on culture from two bodies of literature: knowledge organization and anthropology. Based on the review, we then propose a working definition of culture for knowledge organization research. This definition points to areas of further research concerning culture, ethics, and knowledge organization.

  Lee, H.-L. ; Lee, W.-C.: Proclaiming intellectual authority through classification : the case of the seven epitomes.
  In: Knowledge organization. 38(2011) no.1, S.25-42.
  
  Abstract: The study investigates the main structure of the classification applied in the Seven Epitomes (Qilue), the first documented Chinese library catalog completed a few years before the Common Era. Based on a close examination of the partially extant text and structure of the catalog, other historical records and secondary sources, the authors identify two principal classification methods in the scheme being studied: dichotomy and ranking. It is theorized that the compiler of the catalog, Liu Xin, used ru classicism, or Confucianism, as the principle for guiding the construction of three sets of ranked dichotomies that manifested into the six main classes in the set sequence. As a result, he successfully achieved the chief goal he intended for the catalog-to proclaim classicism as the intellectual authority. This design made the catalog, and its numerous successors in imperial China for two thousand years, an effective aid for intellectual, political, and social control.

  Lim, S.C.J. ; Liu, Y. ; Lee, W.B.: ¬A methodology for building a semantically annotated multi-faceted ontology for product family modelling.
  In: Advanced engineering informatics. 25(2011) no.2, S.147-161.
  
  Abstract: Product family design is one of the prevailing approaches in realizing mass customization. With the increasing number of product offerings targeted at different market segments, the issue of information management in product family design, that is related to an efficient and effective storage, sharing and timely retrieval of design information, has become more complicated and challenging. Product family modelling schema reported in the literature generally stress the component aspects of a product family and its analysis, with a limited capability to model complex inter-relations between physical components and other required information in different semantic orientations, such as manufacturing, material and marketing wise. To tackle this problem, ontology-based representation has been identified as a promising solution to redesign product platforms especially in a semantically rich environment. However, ontology development in design engineering demands a great deal of time commitment and human effort to process complex information. When a large variety of products are available, particularly in the consumer market, a more efficient method for building a product family ontology with the incorporation of multi-faceted semantic information is therefore highly desirable. In this study, we propose a methodology for building a semantically annotated multi-faceted ontology for product family modelling that is able to automatically suggest semantically-related annotations based on the design and manufacturing repository. The six steps of building such ontology: formation of product family taxonomy; extraction of entities; faceted unit generation and concept identification; facet modelling and semantic annotation; formation of a semantically annotated multi-faceted product family ontology (MFPFO); and ontology validation and evaluation are discussed in detail. Using a family of laptop computers as an illustrative example, we demonstrate how our methodology can be deployed step by step to create a semantically annotated MFPFO. Finally, we briefly discuss future research issues as well as interesting applications that can be further pursued based on the MFPFO developed.

  Lee, W.M. ; Sanderson, M.: Analyzing URL queries.
  In: Journal of the American Society for Information Science and Technology. 61(2010) no.11, S.2300-2310.
  
  Abstract: This study investigated a relatively unexamined query type, queries composed of URLs. The extent, variation, and user click-through behavior was examined to determine the intent behind URL queries. The study made use of a search log from which URL queries were identified and selected for both qualitative and quantitative analyses. It was found that URL queries accounted for ?17% of the sample. There were statistically significant differences between URL queries and non-URL queries in the following attributes: mean query length; mean number of tokens per query; and mean number of clicks per query. Users issuing such queries clicked on fewer result list items higher up the ranking compared to non-URL queries. Classification indicated that nearly 86% of queries were navigational in intent with informational and transactional queries representing about 7% of URL queries each. This is in contrast to past research that suggested that URL queries were 100% navigational. The conclusions of this study are that URL queries are relatively common and that simply returning the page that matches a user's URL is not an optimal strategy.

  Lim, S.C.J. ; Liu, Y. ; Lee, W.B.: Multi-facet product information search and retrieval using semantically annotated product family ontology.
  In: Information processing and management. 46(2010) no.4, S.479-493.
  
  Abstract: With the advent of various services and applications of Semantic Web, semantic annotation has emerged as an important research topic. The application of semantically annotated ontology had been evident in numerous information processing and retrieval tasks. One of such tasks is utilizing the semantically annotated ontology in product design which is able to suggest many important applications that are critical to aid various design related tasks. However, ontology development in design engineering remains a time consuming and tedious task that demands considerable human efforts. In the context of product family design, management of different product information that features efficient indexing, update, navigation, search and retrieval across product families is both desirable and challenging. For instance, an efficient way of retrieving timely information on product family can be useful for tasks such as product family redesign and new product variant derivation when requirements change. However, the current research and application of information search and navigation in product family is mostly limited to its structural aspect which is insufficient to handle advanced information search especially when the query targets at multiple aspects of a product. This paper attempts to address this problem by proposing an information search and retrieval framework based on the semantically annotated multi-facet product family ontology. Particularly, we propose a document profile (DP) model to suggest semantic tags for annotation purpose. Using a case study of digital camera families, we illustrate how the faceted search and retrieval of product information can be accomplished. We also exemplify how we can derive new product variants based on the designer's query of requirements via the faceted search and retrieval of product family information. Lastly, in order to highlight the value of our current work, we briefly discuss some further research and applications in design decision support, e.g. commonality analysis and variety comparison, based on the semantically annotated multi-facet product family ontology.

  Wang, W.M. ; Cheung, C.F. ; Lee, W.B. ; Kwok, S.K.: Mining knowledge from natural language texts using fuzzy associated concept mapping.
  In: Information processing and management. 44(2008) no.5, S.1707-1719.
  
  Abstract: Natural Language Processing (NLP) techniques have been successfully used to automatically extract information from unstructured text through a detailed analysis of their content, often to satisfy particular information needs. In this paper, an automatic concept map construction technique, Fuzzy Association Concept Mapping (FACM), is proposed for the conversion of abstracted short texts into concept maps. The approach consists of a linguistic module and a recommendation module. The linguistic module is a text mining method that does not require the use to have any prior knowledge about using NLP techniques. It incorporates rule-based reasoning (RBR) and case based reasoning (CBR) for anaphoric resolution. It aims at extracting the propositions in text so as to construct a concept map automatically. The recommendation module is arrived at by adopting fuzzy set theories. It is an interactive process which provides suggestions of propositions for further human refinement of the automatically generated concept maps. The suggested propositions are relationships among the concepts which are not explicitly found in the paragraphs. This technique helps to stimulate individual reflection and generate new knowledge. Evaluation was carried out by using the Science Citation Index (SCI) abstract database and CNET News as test data, which are well known databases and the quality of the text is assured. Experimental results show that the automatically generated concept maps conform to the outputs generated manually by domain experts, since the degree of difference between them is proportionally small. The method provides users with the ability to convert scientific and short texts into a structured format which can be easily processed by computer. Moreover, it provides knowledge workers with extra time to re-think their written text and to view their knowledge from another angle.

  Lee, W.M.: Publication trends of doctoral students in three fields from 1965-1995.
  In: Journal of the American Society for Information Science. 51(2000) no.2, S.139-144.
  
  Abstract: This study investigates the publication rates of successful doctoral students in the fields of analytical chemistry, experimental psychology, and American literature. Publication rates were calculated for a sample of those receiving doctorates every fifth year between 1965 and 1995. an analysis of the data revealed that there were differences in publication rates of the doctoral students that mirrored differences between the fields as a whole. The data also show that the decline in solo authorship observed in many fields is present in this population as well. Participation rates (percent that had at least one publication) for chemistry and literature showed initial increases followed by plateaus since the early 1980s, while the participation rate in psychology has remained between 40 and 60 % over the course of the study

  Mehtre, B.M. ; Kankanhalli, M.S. ; Lee, W.F.: Content-based image retrieval using a composite color-shape approach.
  In: Information processing and management. 34(1998) no.1, S.109-120.
  
  Abstract: We have proposed a composite feature measure which combines the shape and color features of an image based on a clustering technique. We have also developed a similarity measure to compute the degree of match between a given pair of images. This technique can be used for content-based image retrieval of images using shape and/or color. We have tested our technique on 2 image databases: one consisting of 100 synthetic images, and another database consisting of 500 actual trademarks images. Test results of the proposed scheme for retrieval of images using only shape, only color, and a weighted combination of the two are presented. The efficiency of retrieval is found to be very high and the experimental results are promising for practical applications

  In: Information processing and management. 33(1997) no.3, S.319-337.
  
  Abstract: Discusses effectiveness of several shape measures for content based similarity retrieval of images in multimedia and image database systems. Describes the different shape measures implemented. Given an image all these shape feature measures are computed automatically, and the feature vector can either be used for the retrieval purpose or can be stored in the database for future queries. Tests all thes shape features for image retrieval on a database of 500 trademark images. The average retrieval efficiency values computed over a set of 15 representative queries for all the methods is presented. The output of a sample shape similarity query using all the features is also shown

  In: Information retrieval: data structures and algorithms. Ed.: W.B. Frakes u. R. Baeza-Yates. Englewood Cliffs, NJ : Prentice Hall, 1992. S.393-418.
  
  Abstract: The classical interpretation of Boolean operators in an information retrieval system is in general too strict. A standard Boolean query rarely comes close to retrieving all and only those documents which are relevant to a query. Many models have been proposed with the aim of softening the interpretation of the Boolean operators in order to improve the precision and recall of the search results. This chapter discusses 3 such models: the Mixed Min and Max (MMM), the Paice, and the P-noem models. The MMM and Paice models are essentially variations of the classical fuzzy-set model, while the P-norm scheme is a distance-based approach. Our experimental results indicate that each of the above models provide better performance than the classical Boolean model in terms of retrieval effectiveness

  Abstract: Although thesauri can be solve some problems posed by computerised data base searching (synonyms, generic representation) their compilation requires extensive time and effort of experts and their maintenance is also difficult. Describes how a thesaurus was compiled and maintained automatically by taking advantage of the specially designed formats to input expertise with ease. The thesaurus was named a dynamic thesaurus because it depends on the set of stored data and is adapted to the necessary and sufficient range of keywords. A data base of polymers is taken as an example.
