Community in a diverse society: Using three Western approaches to understand …

In this article three different perspectives on community organization in a Western context – structural, cultural, and critical cultural approaches – are described in order to shed light on the discussion of community development in post-socialist urban China, where the decline of socialist communities has caused increasing concerns about rediscovering community attachment.

Trust in the public sector: is there any evidence for a long-term decline?

Concerns with declining public trust in government have become a permanent element of the contemporary political discourse. This concern also extends to levels of citizens' trust in the public administration and public services. Trust is said to be declining, and this decline is generally seen as detrimental to public service delivery. In this article, we examine the main elements in this…

Autocratic Audience Costs: Regime Type and Signaling Resolve

Scholars of international relations usually argue that democracies are better able to signal their foreign policy intentions than nondemocracies, in part because democracies have an advantage in generating audience costs that make backing down in international crises costly to the leader. This article argues that the conventional hypothesis underestimates the extent to which nondemocratic…

Website usage metrics: A re-assessment of session data

Metrics derived from user visits or sessions provide a means of evaluating Websites and an important insight into online information seeking behaviour, the most important of them being the duration of sessions and the number of pages viewed in a session, a possible busyness indicator. However, the identification of session (termed often ‘sessionization’) is fraught with difficulty in …

Web search engine multimedia functionality

Web search engines are beginning to offer access to multimedia searching, including audio, video and image searching. In this paper we report findings from a study examining the state of multimedia search functionality on major general and specialized Web search engines. We investigated 102 Web search engines to examine: (1) how many Web search engines offer multimedia searching, (2) the …

Searching strategies for the Hungarian language

This paper reports on the underlying IR problems encountered when dealing with the complex morphology and compound constructions found in the Hungarian language. It describes evaluations carried out on two general stemming strategies for this language, and also demonstrates that a light stemming approach could be quite effective. Based on searches done on the CLEF test collection, we find…

Questionnaire mode effects in interactive information retrieval experiments

The questionnaire is an important technique for gathering data from subjects during interactive information retrieval (IR) experiments. Research in survey methodology, public opinion polling and psychology has demonstrated a number of response biases and behaviors that subjects exhibit when responding to questionnaires. Furthermore, research in human–computer interaction has demonstrate…

On the role of user-centred evaluation in the advancement of interactive info…

This paper discusses the role of user-centred evaluations as an essential method for researching interactive information retrieval. It draws mainly on the work carried out during the Clarity Project where different user-centred evaluations were run during the lifecycle of a cross-language information retrieval system. The iterative testing was not only instrumental to the development of a…

User-centred versus system-centred evaluation of a personalization system

Some of the most popular measures to evaluate information filtering systems are usually independent of the users because they are based in relevance judgments obtained from experts. On the other hand, the user-centred evaluation allows showing the different impressions that the users have perceived about the system running. This work is focused on discussing the problem of user-centred ve…

Retrieval of images by spatial and object similarities

In the last several decades it has become an important basis to retrieve images from image databases (IDBs) by the semantic information held in the image objects and the spatial patterns formed by these objects. In this paper, we propose a new method for similarity retrieval of symbolic images by both the attributes and the spatial relationships of the contained objects. The proposed meth…

An information-pattern-based approach to novelty detection

In this paper, a new novelty detection approach based on the identification of sentence level information patterns is proposed. First, “novelty” is redefined based on the proposed information patterns, and several different types of information patterns are given corresponding to different types of users’ information needs. Second, a thorough analysis of sentence level information p…

Using information gain to improve multi-modal information retrieval systems

Nowadays, access to information requires managing multimedia databases effectively, and so, multi-modal retrieval techniques (particularly images retrieval) have become an active research direction. In the past few years, a lot of content-based image retrieval (CBIR) systems have been developed. However, despite the progress achieved in the CBIR, the retrieval accuracy of current systems …

Test theory for evaluating reliability of IR test collections

Classical test theory offers theoretically derived reliability measures such as Cronbach’s alpha, which can be applied to measure the reliability of a set of Information Retrieval test results. The theory also supports item analysis, which identifies queries that are hampering the test’s reliability, and which may be candidates for refinement or removal. A generalization of Classical …

Re-examining the effects of adding relevance information in a relevance feedb…

This paper presents an investigation about how to automatically formulate effective queries using full or partial relevance information (i.e., the terms that are in relevant documents) in the context of relevance feedback (RF). The effects of adding relevance information in the RF environment are studied via controlled experiments. The conditions of these controlled experiments are formal…

A Code of Conduct for Indonesia: Problems and Perspectives

Previous analyses have shown that the success of ethics reforms such as the adoption of codes of ethics and codes of conduct depends on whether legislators have homogeneous ethical standards. In this paper, we discuss why the DPD (upper chamber) and the DPR (lower chamber) of the Indonesian legislature have decided to enact a code of conduct. The paper also presents the results of a surve…
