Abstract

Purpose

This study aims to identify user perception of different qualities of optical character recognition (OCR) in texts. The purpose of this paper is to study the effect of different quality OCR on users' subjective perception through an interactive information retrieval task with a collection of one digitized historical Finnish newspaper.

Design/methodology/approach

This study is based on the simulated work task model used in interactive information retrieval. Thirty-two users made searches to an article collection of Finnish newspaper Uusi Suometar 1869–1918 which consists of ca. 1.45 million autosegmented articles. The article search database had two versions of each article with different quality OCR. Each user performed six pre-formulated and six self-formulated short queries and evaluated subjectively the top 10 results using a graded relevance scale of 0–3. Users were not informed about the OCR quality differences of the otherwise identical articles.

Findings

The main result of the study is that improved OCR quality affects subjective user perception of historical newspaper articles positively: higher relevance scores are given to better-quality texts.

Originality/value

To the best of the authors’ knowledge, this simulated interactive work task experiment is the first one showing empirically that users' subjective relevance assessments are affected by a change in the quality of an optically read text.

Abstract

Purpose

The purpose of this article is to discuss advantages and disadvantages of various means to manage morphological variation of keywords in monolingual information retrieval.

Design/methodology/approach

The authors present a compilation of query results from 11 mostly European languages and a new general classification of the language dependent techniques for management of morphological variation. Variants of the different techniques are compared in some detail in terms of retrieval effectiveness and other criteria. The paper consists mainly of an overview of different management methods for keyword variation in information retrieval. Typical IR retrieval results of 11 languages and a new classification for keyword management methods are also presented.

Findings

The main results of the paper are an overall comparison of reductive and generative keyword management methods in terms of retrieval effectiveness and other broader criteria.

Originality/value

The paper is of value to anyone who wants to get an overall picture of keyword management techniques used in IR.

To show that stem generation compares well with lemmatization as a morphological tool for a highly inflectional language for IR purposes in a best‐match retrieval system.

Abstract

Purpose

To show that stem generation compares well with lemmatization as a morphological tool for a highly inflectional language for IR purposes in a best‐match retrieval system.

Design/methodology/approach

Effects of three different morphological methods – lemmatization, stemming and stem production – for Finnish are compared in a probabilistic IR environment (INQUERY). Evaluation is done using a four‐point relevance scale which is partitioned differently in different test settings.

Findings

Results show that stem production, a lighter method than morphological lemmatization, compares well with lemmatization in a best‐match IR environment. Differences in performance between stem production and lemmatization are small and they are not statistically significant in most of the tested settings. It is also shown that hitherto a rather neglected method of morphological processing for Finnish, stemming, performs reasonably well although the stemmer used – a Porter stemmer implementation – is far from optimal for a morphologically complex language like Finnish. In another series of tests, the effects of compound splitting and derivational expansion of queries are tested.

Practical implications

Usefulness of morphological lemmatization and stem generation for IR purposes can be estimated with many factors. On the average P‐R level they seem to behave very close to each other in a probabilistic IR system. Thus, the choice of the used method with highly inflectional languages needs to be estimated along other dimensions too.

Originality/value

Results are achieved using Finnish as an example of a highly inflectional language. The results are of interest for anyone who is interested in processing of morphological variation of a highly inflected language for IR purposes.

Abstract

Purpose

This paper seeks to examine how an electronic records management system has been used in a Finnish government agency. In particular, it aims to study the relationship between functional classification scheme and the way users in different organisational units and at different organisational levels have employed the system. The goal is to examine whether electronic records management systems were easier to use if the system “knew” what functional classes the user (or other employees in the user's organisational unit) typically need in their work.

Design/methodology/approach

The study is based on two sources. The first source is metadata in records that were captured in the electronic records management system of the agency. It reflects actual behaviour of users when they interact with the system and classification of records. The second source is distribution of functions to organisational units in the light of policy documents and a survey made in the organisation. The study compares the two sources to see how the users have employed the electronic records management system in their work and how this relates to organisational structure and supposed usage of the system.

Findings

In general, individual employees employ only a small part of the classification. However, this does not apply at a higher level in the organisational hierarchy: the higher the person's position in the hierarchy, the more classes he/she is likely to use in the work. Regardless of the position, the classes are generally those identified as belonging to the employee's unit.

Research limitations/implications

The study is based on one agency with a functional organisational structure. The findings may not apply to organisations where job descriptions are fluid. They should also be tested in more complex organisational settings. One could develop new methods of automated classification which combine analysis of document content with contextual reasoning about the likely functional classes.

Practical implications

Access to electronic records management systems could be facilitated by creating in systems user/unit profiles defining what functional classes the user is most likely to need in their work. It would also be useful if systems simply remembered what functional classes the user has needed in the past.

Originality/value

The study offers insight into how an electronic records management system is used in an organisation. This is valuable for companies developing records management software and persons trying to gain a deeper understanding of records management in organisations.

Abstract

In this paper, a hybrid formulation for solving time harmonic eddy current problems in terms of magnetic field h is considered. In particular, we discuss some properties of the implicit boundary condition on the discrete level and the computation of the integral operator exploited in this context. An iterative technique is confirmed to be efficient in solving the arising, partly dense, complex linear system of equations. Furthermore, some test results, including timings for linear solvers are presented.

Abstract

Purpose

The purpose of this paper is to develop a conceptual framework for identifying the primary tensions that business school dean’s encounter when moving between different university contexts.

Design/methodology/approach

The paper is part of a larger research project on the development of business schools. This conceptual paper builds on the studies and personal experiences of business schools and their management in a number of different countries, primarily in Europe, North America, Asia, and the Middle East.

Findings

The present study argues that as a response to the increasing corporatization of higher education, the university sector has fragmented into at least three identifiable contexts: the traditional research university, the academic capitalist university, and the corporate university. The authors conclude that the match between a dean’s worldview and the university context ultimately determines the appropriateness, survival, and success of deanship.

Practical implications

The paper provides practical suggestions for managing business schools. Given that “good” leadership is always context dependent, no single deanship would fit for all business schools. As an outcome, both deans and the selection committees making decisions regarding their recruitment should be sensitive to their worldviews originating from the university contexts in which they previously worked.

Originality/value

Emphasizing a contextual approach to business school leadership, this paper proposes a new typology of deanship situations.

Abstract

Purpose

The purpose of the chapter is to elaborate the theory of academic capitalism by focusing on rarely examined forerunners of academic capitalism: namely, business schools.

Design/methodology/approach

A research-based essay.

Findings

The findings emphasize that there are different forms of academic capitalism. Our example from Dubai context shows how more extreme form of academic capitalism, which we label Acamanic Capitalism, developed as a result of free educational markets.

Originality/value

The chapter provides scholarly value through novel conceptualization. The phenomenon of acamanic capitalism should also be acknowledged in academia and in critical management education.

Abstract

Previous research has been relatively insensitive to the potential combined effects that the shared industry background and country of origin might play in the development of MNCs. This is although there are various external constituents that pose distinctive demands especially on such groups of MNCs. The 15-year period of internationalization of three major Finnish paper companies examined in this study represents MNC development as a collective endeavor in which individual companies are especially influenced both by each other and by their joint external constituents. These influences materialize in analogous timing and patterns of internationalization across individual companies. In its entirety, the study thus suggests that the development of MNCs which operate in the same line of industry and originate from the same country can be considered an outcome of a mutual process that involves interaction both with each other and their shared external constituents. This also means that MNCs then are not only competitors, but simultaneously also a source of mutual support in their ever-continuing evolution.
