The B2B electronic product commerce needs intermediary system to provide an integrated interface for the parts libraries of multiple suppliers. However, it is difficult to automatically integrate the parts libraries because they are heterogeneous. Existing ontology-based approaches show a limited functionality of automated integration of information because Dey can not prevent ontologies from being modeled in different ways, so that the inter-ontology mappings to resolve the heterogeneity become complicated and arbitrary. In order to overcome such problems this paper proposes an ontology modeling framework for parts libraries based on the Guarino's theory of upper ontology. The framework provides knowledge modeling primitives which have explicit formal meanings and modeling principles based on ontological natures. Using the framework, ontology developers can model the knowledge of parts libraries systematically and consistently, so that the resulting ontologies become comparable and uniform and the ontology merging algorithm for the automated information integration can be easily developed.

Ontology-based approaches for automated information integration are being widely investigated. The existing approaches explicitly represent the semantics of information sources in ontologies and let the computer system, through aligning or merging the source ontologies, provide a global view of information sources. The problem of aligning or merging different ontologies is a well known problem, and the inter-ontology mappings play an essential role in information integration. To enable simple and well-founded mappings , the ontologies of information sources should be modeled with the same world view and with the same manner of representation. This paper introduces an ontology modeling framework for component libraries, which is developed based on the Guarino's theory of upper ontology . This paper discusses the results of modeling ontologies of mold and die component libraries based on the framework. A Web-based implementation automatically merges the source ontologies.

Background: To describe domain knowledge consistently and precisely, the establishment of a controlled vocabulary, a so-called ontology, is essential. Internationally, the plant ontology (PO) in the ecology field has been developed for the anatomy and developmental stages of plants in English, Spanish, and Japanese, but there is no Korean version of the PO due to a lack of knowledge on standardization for Korean plants. Objectives: We aimed to establish a Korean plant ontology with core PO architectures. Methods: The latest ontology web language (OWL)-formatted raw version of the PO was collected from the PO consortium site. A formal workflow process and OWL file-handing tools for efficient Korean content development were conducted and executed. Results: The macro- and micro-perspective frameworks of the PO were presented by analyzing the upper model and the internal OWL-leveled physical structure, respectively. We developed and validated Korean knowledge content for a total of 1,957 classes included in the PO and transplanted them into an ontology modeling system. Conclusions: A Korean plant ontology was established for international harmonization through improved compatibility and data exchangeability with multilingual environmental and ecological knowledge bases.

Metadata and folksonomy are two main approaches in representing, organizing, and retrieving resources in the current information environment. Many researches have conducted studies to combine of metadata and folksonomy in order to utilize the strengths of both approaches. This research proposed an approach to utilize both metadata and folksonomy in representing resources by using microcontents. Microcontents in this research is a conceptual structure that reflects dynamic characteristics of folksonomy and the structure of metadata. By connecting folksonomy with metadata through this microcontents structure, both approaches can maximize their strengths and minimize their weaknesses in representing, organizing, and retrieving resources.

This paper aims to suggest a facet-based ontology model that can help sort and access records of dispersed families to address these problems. The facet systematically defines the categories of target concepts, which can create diverse and multiple access points. Using the top-down and bottom-up approaches, the facets, which consist of five upper classes and 18 lower classes, were derived for the records of dispersed families. The proposed ontology model was evaluated by real users. The results show that, overall, the ontology is complete and relevant in terms of access points, availability of context information of the records, and description elements for search and use of the records on dispersed families.

In this paper, we propose Context-based Music Recommendation (COMUS) ontology for modeling user's musical preferences and context and for supporting reasoning about the user's desired emotion and preferences. The COMUS provides an upper Music Ontology that captures concepts about the general properties of music such as title, artists and genre and also provides extensibility for adding domain-specific ontologies, such as Mood and Situation, in a hierarchical manner. The COMUS is music dedicated ontology in OWL constructed by incorporating domain specific classes for music recommendation into the Music Ontology. Using this context ontology, we believe that the use of logical reasoning by checking the consistency of context information, and reasoning over the high-level, implicit context from the low-level, explicit information. As a novelty, our ontology can express detailed and complicated relations among the music, moods and situations, enabling users to find appropriate music for the application. We present some of the experiments we performed as a case-study for music recommendation.

FRBR Library Reference Model is a consolidated model of FR Family Model - FRBR, FRAD, FRSAD developed by IFLA in early 2016. This means the creation of upper model for the consistency of FR individual models. It can be used for the expanding of the discussions on FRBR model in Korea that have been mainly discussed only for the first group of FRBR model. In addition, it can be an opportunity to apply the whole FR Family model to domestic literature in a comprehensive manner. In this study, we analyze the draft of FRBR LRM and apply the model to the Korean classic materials. There are various work, expression, and manifestation related to a work of korean classic material, so it is good to represent the structure of bibliographic information using FR Family model. We built on our experiment using $Prot{\acute{e}}g{\acute{e}}$ to design korean classic materials' ontology modeling, which propose a new orientation of korean classic materials' organizing based on FRBR LRM. As a result, we find out the applicability of the FRBR LRM model on upcoming bibliographical data control environment.
