title: Semantic document representation: Do It with Wikification

authors: Witten, Ian H.

subjects: document representation

abstract: Wikipedia is a goldmine of information. Each article describes a single concept, and together they constitute a vast investment of manual eﬀort and judgment. 
Wikiﬁcation is the process of automatically augmenting a plain-text document with hyperlinks to Wikipedia articles. This involves associating phrases in the document with concepts, disambiguating them, and selecting the most pertinent. All three processes can be addressed by exploiting Wikipedia as a source of data. For the ﬁrst, link anchor text illustrates how concepts are described in running text. For the second and third, Wikipedia provides millions of examples that can be used to prime machine-learned algorithms for disambiguation and selection respectively. 
Wikiﬁcation produces a semantic representation of any document in terms of concepts. We apply this to (a) select index terms for scientiﬁc documents, and (b) determine the similarity of two  documents, in both cases outperforming humans in terms of agreement with human judgment. I will show how it can be applied to document clustering and classiﬁcation algorithms, and to produce back of the book indexes, improving on the state of the art in each case.

title: Analysis of market entry strategies by New Zealand companies doing business with Taiwan

authors: Chung, Henry (Fuan-Lin)

abstract: Many issues need to be considered when firms decide to internationalise their operations. One key issue is to decide the best way to service a particular foreign market. Because of its central role in international operations, entry mode is described as a “frontier issue”. The choice of market entry mode is considered as one of the most critical decisions facing international firms because it has a decisive impact on the success of a firm’s international operations.

Findings on New Zealand firms’ choice of market entry modes are either incomplete or far from comprehensive. This study is designed to examine the choice of market entry mode of New Zealand companies conducting business with Taiwan. Unlike previous research, this study is the first of its type to include international distribution system and business system theories as part of the market entry mode choice framework.

This study, by examining selected factors influencing the choice of market entry mode of 124 New Zealand firms conducting business with Taiwan, had generated a number of interesting findings. Empirical results suggested that the choice of market entry modes was significantly influenced by the host market’s business system, product type, ownership of the company, market size of the industry, market portfolio, international business experience, and host market retailing system. Immigrant links also proved to be a factor influencing a firm’s choice of market entry mode. Firms established by immigrants originating from the host country did not follow the traditional incremental internationalisation theory. Factors such as firm size, before-after sales service, product differentiation, competitors’ choice, home market position, and market potential of the industry were not found to be related to firms’ choice of market entry mode behaviour.

The key statistical analysis tool employed in the study was binary logistic regression analysis. As a result of the logistic regression analysis testing, a research framework on which future inquiries might be based was established.

title: Editorial

authors: Clarkin-Phillips, Jeanette

abstract: As New Zealand contemplates wholesale review of the formal schooling system and the leadership implications thereof, the winds of educational change begin to swirl. Not the persistent, yet gentle flutter of change that evolves the educational landscape in almost imperceptible ways, but tumultuous paradigmatic gales that potentially change it beyond all recognition. Heralded by politicians, economists and capitalists, there is little doubt that the 1989 neoliberal tempest wrought havoc on notions of community and profession. The whirlwind shift from social democracy to market competition, managerialism and performativity saw critical voices silenced and educators disparagingly positioned as self-interested providers. In the rush to legislate Tomorrow’s Schools, 18,000 submissions remained unanalysed and therein lies a crucial lesson: we ignore research at our peril. As educators, we have a moral obligation to generate, disseminate and critique understandings of leadership, policy and practice; to remain open to counter perspectives; and to contribute positively and hopefully to research that empowers and emancipates. Consistent with JELPP’s commitment to honouring diversity in leadership focus, setting, and authorship, articles in this year’s general edition offer fresh insight into topics of interconnected and perennial importance: native knowledge, instructional leadership, indigenous teachers, appraisal, professional values, and safe schools.
