Abstract

While the concept of vital statistics is rich in meaning, standardization of these valuable data has eluded governments, intergovernmental organizations (IGOs), non‐governmental organizations (NGOs), and demographic researchers. Primarily due to discrepancies of sociopolitical systems and availability of resources, international vital statistics are diverse and variant in terms of vital classification and registration and data processing and reporting. That said, birth, death, marriage, and divorce data are generally included in reported vital statistics. In recent decades, research institutes, universities, IGOs particularly the United Nations (UN), and NGOs have been working hard to organize, collect, and disseminate vital statistics from developing countries. This article analytically presents an overview of global patterns of vital registrations and numerations. It examines the major resources of international vital statistics, including registers, surveys, and print and digital materials. This literature presents a selection of surveys, monographs, serials, periodicals, databases, portals, and homepages based on their relevancy to information and scholarship related to international vital statistics.

Abstract

Purpose

Citation content in academic papers and academic monographs promotes the knowledge flow among different publications. However, existing citation content analysis (CCA) focuses on academic papers and monographs have not received much research attention. We want to know if monographs are appropriate objects of CCA and whether existing methods of analyzing citation in papers are suitable for citation in monographs. Therefore, this paper aims to learn more about features of cited references and citation content in monographs and compare the characteristic of citation pattern between monographs and papers.

Design/methodology/approach

The authors manually annotate the references and syntactic citation content in academic monographs published by Morgan & Claypool and automatically extracted the references and citation content from academic papers published by Public Library of Science. Five features in two types citation pattern, namely, pattern of cited reference (including year, source and mention frequency of reference) and pattern of citation content (including location, length of citation content) are used to examine similarities and differences between monographs and papers.

Findings

The results indicate that between monographs and papers, differences are shown in location, length of citation content and year, source of reference, whereas frequency of mention of reference is similar.

Originality/value

Previous studies have explored the patter of citation content in academic papers. However, none of the existing literature, as far as the authors know, has considered the citation content in academic monographs and the similarities or differences among academic documents when studying the citation pattern.

Abstract

Purpose

No scholarly publications have systematically studied the evolution and growth of China's scientific papers of library and information science published in the English language and covered by ISI during the reform era starting in 1979. It is intended that this paper should fill this gap.

Design/methodology/approach

This study surveys ISI library and information science papers authored by researchers of China during 1979‐2009 and quantitatively presents the development of scholarly publications authored by researchers from China. A total of 30 years of data of ISI literature are collected and analyzed, and the paper conducts an international comparison of research productivity among leading Asian countries.

Findings

The paper establishes the patterns and trends of papers authored by Chinese authors, particularly the top subject areas and top journals in which Chinese papers are highly represented. Besides, the paper makes an international comparison between China and other major Asian countries such as India, Japan, and Korea in terms of library and information science research outputs represented in ISI literature. China has become the leader in terms of research productivity of library and information science.

Research limitations/implications

This study focuses on English‐language journal articles only. Only journals meeting ISI inclusion criteria are reviewed and analyzed. The possible accidentally inaccurate entries in the original ISI data have not been checked for accuracy and consistency for each journal article record.

Originality/value

The paper provided an example of using the powerful ISI databases of citation indexes, particularly ISI SCCI, in a cautious and critical way. It empirically presents the overall upward development of China's scholarship of library and information science. Either the Greater China area as a whole or Mainland China alone has become the leader in the scholarly publications in library and information ahead of India, Korea and Japan.

Abstract

Basic education (primary and junior secondary schooling) in China has experienced phenomenal development in the reform era from the late 1970s. The most important reform policies; namely, decentralization of governance and diversification of finance, have been translated into an unprecedented scale of resource mobilization for schooling expansion. This article examines China’s education finance reform and basic education development. It analyzes international aid and assistance, particularly major basic education projects financed by the World Bank and other international organizations. The article argues that China is not necessarily “in the driving seat” in cooperation with the World Bank, and that the bank does not play purely “a pivotal positive role” in helping develop Chinese basic education. In spite of its huge aid and assistance in China, the bank, to a certain extent, also contributes to the formation of China’s bifurcated schooling system.

Abstract

The past two decades have witnessed the rapid developments in distance education. Though debates surrounding issues related to distance education have yet abated, more and more institutions, entrepreneurs, educators, and learners embrace distance education with the aid of improved information technologies. The present guide introduces the historical development, major theories, and leading agencies and organizations associated with the discipline. Furthermore, it provides an annotated selection of resources including periodicals, books and monographs, and Internet sites. Though emphasis is placed on representative resources and information of distance education of the USA, important international resources are also analytically introduced.

Abstract

Purpose

Based on user-generated content from a Chinese social media platform, this paper aims to investigate multiple methods of constructing user profiles and their effectiveness in predicting their gender, age and geographic location.

Design/methodology/approach

This investigation collected 331,634 posts from 4,440 users of Sina Weibo. The data were divided into two parts, for training and testing . First, a vector space model and topic models were applied to construct user profiles. A classification model was then learned by a support vector machine according to the training data set. Finally, we used the classification model to predict users’ gender, age and geographic location in the testing data set.

Findings

The results revealed that in constructing user profiles, latent semantic analysis performed better on the task of predicting gender and age. By contrast, the method based on a traditional vector space model worked better in making predictions regarding the geographic location. In the process of applying a topic model to construct user profiles, the authors found that different prediction tasks should use different numbers of topics.

Originality/value

This study explores different user profile construction methods to predict Chinese social media network users’ gender, age and geographic location. The results of this paper will help to improve the quality of personal information gathered from social media platforms, and thereby improve personalized recommendation systems and personalized marketing.

Abstract

Purpose

The development of social media has led to large numbers of internet users now producing massive amounts of user-generated content (UGC). UGC, which shows users’ opinions about events directly, is valuable for monitoring public opinion. Current researches have focused on analysing topic evolutions in UGC. However, few researches pay attention to emotion evolutions of sub-topics about popular events. Important details about users’ opinions might be missed, as users’ emotions are ignored. This paper aims to extract sub-topics about a popular event from UGC and investigate the emotion evolutions of each sub-topic.

Design/methodology/approach

This paper first collects UGC about a popular event as experimental data and conducts subjectivity classification on the data to get subjective corpus. Second, the subjective corpus is classified into different emotion categories using supervised emotion classification. Meanwhile, a topic model is used to extract sub-topics about the event from the subjective corpora. Finally, the authors use the results of emotion classification and sub-topic extraction to analyze emotion evolutions over time.

Findings

Experimental results show that specific primary emotions exist in each sub-topic and undergo evolutions differently. Moreover, the authors find that performance of emotion classifier is optimal with term frequency and relevance frequency as the feature-weighting method.

Originality/value

To the best of the authors’ knowledge, this is the first research to mine emotion evolutions of sub-topics about an event with UGC. It mines users’ opinions about sub-topics of event, which may offer more details that are useful for analysing users’ emotions in preparation for decision-making.
