Abstract: On a scientific concept hierarchy, a parent concept may have a few attributes, each of which has multiple values being a group of child concepts. We call these attributes facets: classification has a few facets such as application (e.g., face recognition), model (e.g., svm, knn), and metric (e.g., precision). In this work, we aim at building faceted concept hierarchies from scientific literature. Hierarchy construction methods heavily rely on hypernym detection, however, the faceted relations are parent-to-child links but the hypernym relation is a multi-hop, i.e., ancestor-to-descendent link with a specific facet "type-of". We use information extraction techniques to find synonyms, sibling concepts, and ancestor-descendent relations from a data science corpus. And we propose a hierarchy growth algorithm to infer the parent-child links from the three types of relationships. It resolves conflicts by maintaining the acyclic structure of a hierarchy.

Abstract

While classifications are heavily used to categorize web content, the evolution of the web foresees a more formal structure - ontology - which can serve this purpose. Ontologies are core artifacts of the Semantic Web which enable machines to use inference rules to conduct automated reasoning on data. Lightweight ontologies bridge the gap between classifications and ontologies. A lightweight ontology (LO) is an ontology representing a backbone taxonomy where the concept of the child node is more specific than the concept of the parent node. Formal lightweight ontologies can be generated from their informal ones. The key applications of formal lightweight ontologies are document classification, semantic search, and data integration. However, these applications suffer from the following problems: the disambiguation accuracy of the state of the art NLP tools used in generating formal lightweight ontologies from their informal ones; the lack of background knowledge needed for the formal lightweight ontologies; and the limitation of ontology reuse. In this dissertation, we propose a novel solution to these problems in formal lightweight ontologies; namely, faceted lightweight ontology (FLO). FLO is a lightweight ontology in which terms, present in each node label, and their concepts, are available in the background knowledge (BK), which is organized as a set of facets. A facet can be defined as a distinctive property of the groups of concepts that can help in differentiating one group from another. Background knowledge can be defined as a subset of a knowledge base, such as WordNet, and often represents a specific domain.

Abstract: In this thesis we propose three new word association measures for multi-word term extraction. We combine these association measures with LocalMaxs algorithm in our extraction model and compare the results of different multi-word term extraction methods. Our approach is language and domain independent and requires no training data. It can be applied to such tasks as text summarization, information retrieval, and document classification. We further explore the potential of using multi-word terms as an effective representation for general web-page summarization. We extract multi-word terms from human written summaries in a large collection of web-pages, and generate the summaries by aligning document words with these multi-word terms. Our system applies machine translation technology to learn the aligning process from a training set and focuses on selecting high quality multi-word terms from human written summaries to generate suitable results for web-page summarization.

Abstract: This paper reports on the second part of an initiative of the authors on researching classification systems with the conceptual model defined by the Functional Requirements for Subject Authority Data (FRSAD) final report. In an earlier study, the authors explored whether the FRSAD conceptual model could be extended beyond subject authority data to model classification data. The focus of the current study is to determine if classification data modeled using FRSAD can be used to solve real-world discovery problems in multicultural and multilingual contexts. The paper discusses the relationships between entities (same type or different types) in the context of classification systems that involve multiple translations and /or multicultural implementations. Results of two case studies are presented in detail: (a) two instances of the DDC (DDC 22 in English, and the Swedish-English mixed translation of DDC 22), and (b) Chinese Library Classification. The use cases of conceptual models in practice are also discussed.

Abstract: Standard library classification systems like Dewey Decimal Classification (DDC), U.S. Library of Congress Classification (LCC), and Universal Decimal Classification (UDC) are internationally known and widely used by libraries as the tools for organizing information. Charles Ammi Cutter's Expansive Classification (EC), James Duff Brown's Subject Classification (SC), Henry E. Bliss' Bibliographic Classification (BC), and S. R. Ranganathan's Colon Classification (CC) also are standard classification systems, but they are less commonly used compared to aforementioned three systems. All these systems are easy to use and convenient for most general collection libraries. However, these systems are not adequate for some special collections. Libraries with rich collections on Islam also face problems while using these systems, although such libraries often use expansions in the original systems for their collections. This paper examines this problem and presents a potential optimal solution. The author collected data, using a semistructured interview technique, from a representative sample of thirty libraries in eight countries with strong collections in Islam. These data were analyzed employing qualitative methods.

Abstract: This research concerns the frequency of the assignment of author-supplied keyword strings and cataloger supplied subject heading strings within a library catalog. The results reveal that, on average, more author-assigned keywords and more cataloger-assigned Library of Congress Subject Headings were assigned to works emerging from the arts & humanities than to works emerging from the social sciences and science, technology, engineering, and mathematics (STEM) disciplines. STEM disciplines in particular received a lower amount of topical metadata, in part because of the under-assignment of name/title, geographical, and corporate subject headings. These findings reveal how librarians could increase their understanding of how topical access is functioning within academic disciplines.

Abstract: An African Studies Thesaurus was constructed for the purpose of subject indexing and retrieval in the Library of the African Studies Centre (ASC) in Leiden in 2001-2006. A word-based system was considered a more user-friendly alternative to the Universal Decimal Classification (UDC) codes which were used for subject access in the ASC catalogue at the time. In the process of thesaurus construction UDC codes were used as a starting point. In addition, when constructing the thesaurus, each descriptor was also assigned a UDC code from the recent edition of the UDC Master Reference File (MRF), thus replacing many of the old UDC codes used by then, some of which dated from the 1952 French edition. The presence of the UDC codes in the thesaurus leaves open the possibility of linking the thesaurus to different language versions of the UDC MRF in the future. In a parallel but separate operation each UDC code which had been assigned to an item in the library's catalogue was subsequently converted into one or more thesaurus descriptors.

Abstract: The National Library of Latvia (NLL) made a decision to use the Library of Congress Subject Headings (LCSH) in 2000. At present the NLL Subject Headings Database in Latvian holds approximately 34,000 subject headings and is used for subject cataloging of textual resources, including articles from serials. For digital objects NLL uses a system like Faceted Application of Subject Terminology (FAST). We succesfully use it in the project "In Search of Lost Latvia," one of the milestones in the development of the subject cataloging of digital resources in Latvia.

Abstract

From the very beginnings of library automation, subject authority control has been considered an important bibliographic tool in the Czech National Library (CNL). Effective subject access cannot exist without standardised access points. Subject authorities are considered an indispensable reference tool in supporting the selection of subject access points and normalizing content indexing. Most importantly, they are heavily relied upon when it comes to customisation of links between bibliographic records and subject access points in order to create a user-friendly subject browsing and searching environment. Because of the fact that the Universal Decimal Classification (UDC) is widely used in Czech Libraries it has become a readily available language independent subject framework which can be complemented by a more user-friendly subject heading system. In this context, the subject authority control offers a means of enhancing subject headings' access points with terminology and the semantic links available in UDC. Furthermore classification is used to enrich relationships between authority records themselves. The author will discuss in more detail the different aspects and advantages of subject authorities in which a classification and a subject heading system complement one another and the way this is implemented in the CNL.

Abstract

Provision of high-quality subject metadata is crucial for organizing adequate subject access to rich content aggregated by digital libraries. A number of large-scale digital libraries worldwide are now generating subject metadata to describe not only individual objects but entire digital collections as an integral whole. However, little research to date has been conducted to empirically evaluate the quality of this collection-level subject metadata. The study presented in this article compares free-text and controlled-vocabulary collection-level subject metadata in three large-scale cultural heritage digital libraries in the United States and the European Union. As revealed by this study, the emerging best practices for creating rich collection-level subject metadata includes describing a collection's subject matter with mutually complementary data values in controlled-vocabulary and free-text subject metadata elements. Three kinds of complementarity were observed in this study: one-way complementarity, two-way complementarity, and multiple complementarity.
