    Abstract
    The Many Using and Creating Hypermedia (MUCH) systems is based on the Dexter model and treats the storage layer as a semantic net. The MUCH system provides a numer of recommended link types for representing application domain concepts, such as thesauri, documents and annotations. users of the system are expected to use those link types in the course of authoring meaningful hypermedia. based on the logs of usage of the MUCH system over 2 years by over 200 people, contrary to the designers' expectations, users did not exploit the ability to type semantic links. Typically authors used the default link type regardless of their semantic intentions. When a link type other than the default type was chosen, that choice was often inconsistent with the way another user would able a similar link. The system has proven to be useful for authoring conventional documents. Authors, however, were not practically able to produce hypertext documents. Based on these experiences a new system, RICH (Reusable Intelligent Collaborative Hypermedia), has been designed and built which emphasizes rules for typing links and maintaining the integrity of the semantic net

    Abstract
    The aim of this paper is to map the foci of research in doctoral dissertations on tourism in China. In the paper, coword analysis is applied, with keywords coming from six public dissertation databases, i.e. CDFD, Wanfang Data, NLC, CALIS, ISTIC, and NSTL, as well as some university libraries providing doctoral dissertations on tourism. Altogether we have examined 928 doctoral dissertations on tourism written between 1989 and 2013. Doctoral dissertations on tourism in China involve 36 first level disciplines and 102 secondary level disciplines. We collect the top 68 keywords of practical significance in tourism which are mentioned at least four times or more. These keywords are classified into 12 categories based on co-word analysis, including cluster analysis, strategic diagrams analysis, and social network analysis. According to the strategic diagram of the 12 categories, we find the mature and immature areas in tourism study. From social networks, we can see the social network maps of original co-occurrence matrix and k-cores analysis of binary matrix. The paper provides valuable insight into the study of tourism by analyzing doctoral dissertations on tourism in China.

    Abstract
    In the interest of standardization and quality assurance, it is desirable for authors and staff of access services to follow the American National Standards Institute (ANSI) guidelines in preparing abstracts. Using the statistical approach an extraction system (the Abstraction Assistant) was developed to generate informative abstracts to meet the ANSI guidelines for structural content elements. The system performance is evaluated by comparing the system-generated abstracts with the author's original abstracts and the manually enhanced system abstracts on three criteria: balance (satisfaction of the ANSI standards), fluency (text coherence), and understandability (clarity). The results suggest that it is possible to use the system output directly without manual modification, but there are issues that need to be addressed in further studies to make the system a better tool.
