Chinese college students' Web querying behaviors:A case study of Peking University

This study examined users' querying behaviors based on a sample of 30 Chinese college students from Peking University. The authors designed 5 search tasks and each participant conducted two randomly selected search tasks during the experiment. The results show that when searching for pre-designed search tasks, users often have relatively clear goals and strategies before searching. When formulating their queries, users often select words from tasks, use concrete concepts directly, or extract 'central words' or keywords. When reformulating queries, seven query reformulation types were identified from users' behaviors, i.e. broadening, narrowing, issuing new query, paralleling, changing search tools, reformulating syntax terms, and clicking on suggested queries. The results reveal that the search results and/or the contexts can also influence users' querying behaviors.

Identification and Analysis of Multi-tasking Product Information Search Sessions with Query Logs

Purpose： This research aims to identify product search tasks in online shopplng ana analyze the characteristics of consumer multi-tasking search sessions. Design/methodology/approach： The experimental dataset contains 8,949 queries of 582 users from 3,483 search sessions. A sequential comparison of the Jaccard similarity coefficient between two adjacent search queries and hierarchical clustering of queries is used to identify search tasks. Findings： （1） Users issued a similar number of queries （1.43 to 1.47） with similar lengths （7.3-7.6 characters） per task in mono-tasking and multi-tasking sessions, and （2） Users spent more time on average in sessions with more tasks, but spent less time for each task when the number of tasks increased in a session. Research limitations： The task identification method that relies only on query terms does not completely reflect the complex nature of consumer shopping behavior.Practical implications： These results provide an exploratory understanding of the relationships among multiple shopping tasks, and can be useful for product recommendation and shopping task prediction. Originality/value： The originality of this research is its use of query clustering with online shopping task identification and analysis, and the analysis of product search session characteristics.

Understanding information seeking behavior of rural women:Field studies in China

Purpose:The purpose of this research is to investigate Chinese rural women’s information needs and information seeking behavior,with an emphasis on exploration of the intervening variables that influence information needs and information seeking behavior.Design/methodology/approach:The sample consisted of 27 women from 9 villages in Gansu Province,Anhui Province and Tianjin City,China.Data were collected through in-depth individual interview.Both quantitative and qualitative methods were employed to analyze the data.Findings:Chinese rural women’s needs are basically tied to agricultural technologies,employment and health information.Social network,rather than the Internet,serves as the most frequently used information channel.Women’s cognitive ability,social role and their living environment are the 3 intervening variables that have an impact on their information needs and their information seeking behavior.Research limitations:This qualitative research is based on a small sample and conducted on specific socio-economic settings in China,which may restrict the generalization and application of relevant findings in other settings and countries.Practical implications:The study results will help librarians and information professionals better understand Chinese rural women’s information needs and information seeking behavior in an effort to find ways to solve problems they may encounter in their information seeking process.Originality/value:This paper introduced an analysis framework that provides an integrated perspective on understanding information needs and information seeking behavior of Chinese women in rural areas.

An empowerment evaluation framework for national scientific and technical information governance

‘Empowerment’is the result of pursuing special capabilities under a specific value orientation.The changes in related object capabilities triggered by scientific and technical information activities in the new environment are important to the national scientific and technical(S&T)information governance.Based on the empowerment theories and evaluation practices,this study attempts to construct an empowerment evaluation framework for national S&T information governance and takes the participatory technology assessment and Altmetrics methods as examples to demonstrate its advantages:1)The capability changes and development potential are regarded as important basis for evaluation;2)The multi-person participation and multi-indicator comprehensive evaluation method is conducive to the democratic and objective nature of science and technology information governance policy formulation.

Ontology modeling of semantics in social media:Public issue knowledge base (PIKB)of the Weibo

Purpose:This study aims to construct an ontology to model the semantics of social media streams,in particular,trending topics and public issues.Design/methodology/approach:Our knowledge base included 10 public events and topics from Weibo respectively,which were collected through keyword search and a crawler program.We used a semi-automatic approach to model and annotate the semantics in social media,and adapted the multi-layered ontology to refine the design based on previous researches,then we used named entity recognition(NER) to extract entities to instantiate the ontology.Relationships were extracted based on co-occurrence measures.Finally,we manually conducted post-filtering evaluation and edited the extracted entities and relationships.Findings:An initial assessment demonstrated that our multi-layered ontology supports various types of queries and analyses in the public issue knowledge base(PIKB),which can serve as an effective tool to query,understand and trace public issues.Research limitations:Manual involvement cannot meet the requirements for challenges of sustainable developments.Since the relationships extracted are fully based on the co-occurrence of entities,rich semantic relationships,such as how much the key players have been involved,could not be fully reflected.Besides,the user evaluation is necessary for further ontology assessment.Practical implications:The PIKB can be used by regular Web users and policy makers to query,understand,and make sense of public events and topics.The methodology and reusable ontology model are useful for institutions that are interested in making use of the social media data.Originality/value:In this study,a multi-layered ontology is applied to model the evolving semantics of public events and trending topics in social media,and the semi-automatic approach could make it possible to extract entities and relationships from large amount of unstructured short texts of user generated content(UGC) from social media.

An empirical study on classification of patent life patterns

With the theoretical framework of patent information life cycle,this research studies the relationship between patents' life patterns and technological development stages of the relevant field,using life status in patent information life cycle as the research dimension. Data of patents issued in the field of wireless charging are retrieved from the United States Patent and Trademark Office Library. Citation information about these patents is also collected. By analyzing the temporal citation count data of patent information,the patents' life patterns using the RSD/P classification method are classified. This study found that the emergence of different life patterns of patent information has strong connection with the technological stage in which the patent information is located,and sleeping beauty patents have high hidden values. In the stage of technological development,attention should be paid to the identification of non-stationary patents. Rapid identification of high-value patents,i. e.,patents with certain life pattern,is instrumental to accelerate the development of technologies. This study provides a viable approach for identifying high-value patents of emerging technologies through empirical research.

Development in theoretical study and practice of library legislation in China

One of the most outstanding characteristics of library legislation in China is that theoretical research and legislative practice are mutually reinforcing, making important issues and basic rules and regulations closely associated with legislation and the research focus. A national library law is currently being enacted while several local library legislations have already seen fruitful results. In the enactment of 'Regulations for the Protection of Information Network Dissemination Rights', the library professional participated for the first time in enacting a national copyright law, which led to unprecedented flourishing of library activities and copyright studies. The promulgation of another legal framework,'Government Information Disclosure Regulations' further advanced the research on related issues and pushed forward government information services in public libraries in the same way. A new landmark for library legislation in recent years is the promulgation of'Guidelines for Land Utilization for Public Library Construction' and 'Public Library Construction Standards', while the framing of 'Rules of Professional Ethics for Librarians in China(On trial)' and the 'Library Service Manifesto' give indication that a framework of self-disciplinary measures of library professionals is established.

Research on Intelligent Organization and Application of Multi-source Heterogeneous Knowledge Resources for Energy Internet

To improve the informationization and intelligence of the energy Internet industry and enhance the capability of knowledge services,it is necessary to organize the energy Internet body of knowledge from existing knowledge resources of the State Grid,which have the characteristics of large scale,multiple sources,and heterogeneity.At the same time,the business fields of State Grid cover a wide range.There are many sub-fields under each business field,and the relationship between fields is diverse and complex.The key to establishing the energy Internet body of knowledge is how to fuse the heterogeneous knowledge resources from multiple sources,extract the knowledge contents from them,and organize the different relationships.This paper considers transforming the original knowledge resources of State Grid into a unified and wellorganized knowledge system described in OWL language to meet the requirements of heterogeneous resource integration,multi-source resource organization,and knowledge service provision.For the State Grid knowledge resources mainly in XML format,this paper proposes a Knowledge Automatic Fusion and Organization idea and method based on XSD Directed Graph.According to the method,the XML corresponding XSD documents are transformed into a directed graph in the first stage during which the graph neural network detects hidden knowledge inside the structure to add semantic information to the graph.In the second stage,for other structured knowledge resources(e.g.,databases,spreadsheets),the knowledge contents and the relationships are analyzed manually to establish the mappings from structured resources to graph structures,using which the original knowledge resources are transformed into graph structures,and merged with the directed graphs obtained in the first stage to achieve the fusion of heterogeneous knowledge resources.And expert knowledge is introduced for heterogeneous knowledge fusion to further extend the directed graph.And in the third stage,the expanded directed graph is converted to the body of knowledge in the form of OWL.This paper takes the knowledge resources in the field of human resources of the State Grid as an example,to establish the ontology of the human resources training field in a unified manner,initially demonstrating the effectiveness of the proposed method.

Web users' language utilization behaviors in China

The paper focuses on the habits of China Web users' language utilization behaviors in accessing the Web. It also seeks to make a general study on the basic nature of language phenomenon with regard to digital accessing. A questionnaire survey was formulated and distributed online for these research purposes. There were 1,267 responses collected. The data were analyzed with descriptive statistics, Chi-square testing and contingency table analyses. Results revealed the following findings. Tagging has already played an important role in Web2.0 communication for China's Web users. China users rely greatly on all kinds of taxonomies in browsing and have also an awareness of them in effective searching. These imply that the classified languages in digital environment may aid Chinese Web users in a more satisfying manner. Highly subject-specific words, especially those from authorized tools, yielded better results in searching. Chinese users have high recognition for related terms. As to the demographic aspect, there is little difference between different genders in the utilization of information retrieval languages. Age may constitute a variable element to a certain degree. Educational background has a complex effect on language utilizations in searching. These research findings characterize China Web users' behaviors in digital information accessing. They also can be potentially valuable for the modeling and further refinement of digital accessing services.

A discourse on creating and rendering educational and cultural enrichment services to rural migrant workers by public libraries

As far as China's enormous success in her economic reforms and development is concerned,Chinese rural migrant workers indeed have had their biggest share of contributions.Yet ironically in return,they have only received a disproportionate meager share of benefit rewards.These people represent a huge economically deprived group at the bottom of the social totem pole in China's metropolises.On the whole as a social group,their educational attainment is relatively low as compared to their average urban coworkers.As such being the case,their rights to access some of the cost-free cultural and educational enrichment programs in the society are limited and not always assured.Nevertheless and in general speaking,they manifest a strong and consistent desire to acquire all sorts of new and practical knowledge by means of accessing the resources and facilities of their local public libraries.It is suggested in this paper that public libraries are in a good position to give strong support to the central government's strategic planning for the development of a public culture service systema).In implementing such a government initiative with an unswerving purpose of advancing social justice and equality,public libraries should strife to provide as many as possible their library services at no cost to the public,especially to those socially deprived rural migrant workers.

Towards impact tenacity of academic institutions: A case study in Informetrics

Academic institutions are important subjects of discipline construction and knowledge production.It is crucial to study and evaluate the impact of institutions,and scientific evaluation is conducive to the development of academic institutions and the improvement of organizational efficiency.Most of the existing bibliometric indicators measure the impact of academic institutions from the perspective of citations(or variations).In this paper,we focus on a different side of their impact,namely tenacity.We conceptualize impact tenacity of academic institutions and define a series of indicators for operationalization.Besides,we implement correlation analysis and principal component analysis to explore whether the impact tenacity indicators and other bibliometric indicators are related and on the same dimension,taking informetrics as the representative discipline.We find that there was a significant negative correlation between the defined impact tenacity and number of papers,number of citations,and number of authors,and involved indicators(i.e.,impact tenacity and other involved bibliometric indicators)describe two almost orthogonal dimensions.Moreover,this paper also selects the Max Planck Society and Taiwan Applied Research Laboratories(China)as case studies,and reveals that low-tenacity and high-tenacity institutions have quite different characteristics.Based on these findings,we make some constructive suggestions for research policy makers,such as considering maintaining a high tenacity of institutions by supplementing more academic training.

Exploring information divide based on a theoretical view of information source horizon

This study sheds light on the information divide based on a theoretical view of Information Source Horizon proposed by Reijo Savolainen. Through a field study, the subjective factors and objective factors have been explored. Aiming to understand the differentiation of information richness or poorness among various people, this paper makes a comparative analysis on the broadness of information source horizon across different groups divided by demographics. Firstly, information richness is not only utilizing the socially designed information space adequately, but also brings subjective dynamics into information practice initiatively. Secondly, people who are unable to get access to these types of information sources own a relatively high possibility to fall into poor information situations. Thirdly, a complex relationship is built between the broadness of information source horizon and demographics of the sample. This study tries to interpret the information divide through a new theoretical perspective, and thus this endeavor is helpful for deepening of information divide research. The findings of this study imply new ideas for governance of information poverty. Creative connections between information source horizon theory and information divide phenomena have been made. Therefore, we contribute a new exploration and explanation for information divide.

Directionality of paper reviewing and publishing of a scientist: A Granger causality inference

It has been evidenced that peer review activities are positively correlated to scientists’bibliometric performance(e.g.,Ortega,2017,2019).However,how the number of paper’reviewing’interacts with a scientist’s’publishing’has not been addressed in previous studies.This paper attempts to employ the Granger causality inference to explore the directionality between a scientist’s publication performance and his/her review activities.Our dataset comprises scientists’reviewed articles derived from Publons in the Web of Knowledge database,and their publications retrieved from Pub Med.We find that scientists who reviewed less or published less tend to have Granger causality between reviewing and publishing activities.In addition,compared with early-career researchers,reviewing advances publishing for senior scientists.

Uncovering Topics of Public Cultural Activities: Evidence from China

In this study, we uncover the topics of Chinese public cultural activities in 2020 with a two-step short text clustering(self-taught neural networks and graph-based clustering) and topic modeling approach. The dataset we use for this research is collected from 108 websites of libraries and cultural centers, containing over 17,000 articles. With the novel framework we propose, we derive 3 clusters and 8 topics from 21 provinciallevel regions in China. By plotting the topic distribution of each cluster, we are able to shows unique tendencies of local cultural institutes, that is, free lessons and lectures on art and culture, entertainment and service for socially vulnerable groups, and the preservation of intangible cultural heritage respectively. The findings of our study provide decision-making support for cultural institutes, thus promoting public cultural service from a data-driven perspective.

A Study of Detecting Student Engagement Modes in an Online Learning Platform

In this paper,we used the platform log data to extract three features(proportion of passive video time,proportion of active video time,and proportion of assignment time)aligning with different learning activities in the Interactive-Constructive-Active-Passive(ICAP)framework,and applied hierarchical clustering to detect student engagement modes.A total of 840 learning rounds were clustered into four categories of engagement:passive(n=80),active(n=366),constructive(n=75)and resting(n=319).The results showed that there were differences in the performance of the four engagement modes,and three types of learning status were identified based on the sequences of student engagement modes:difficult,balanced and easy.This study indicated that based on the ICAP framework,the online learning platform log data could be used to automatically detect different engagement modes of students,which could provide useful references for online learning analysis and personalized learning.
