1Wang, P. ; Ma, Y. ; Xie, H. ; Wang, H. ; Lu, J. ; Xu, J.: "There is a gorilla holding a key on the book cover" : young children's known picture book search strategies.
In: Journal of the Association for Information Science and Technology. 73(2022) no.1, S.45-57.
Abstract: There is no information search system can assist young children's known picture book search needs since the information is not organized according to their cognitive abilities and needs. Therefore, this study explored young children's known picture book search strategies and extracted picture book search elements by simulating a search scenario and playing a picture book search game. The study found 29 elements children used to search for known picture books. Then, these elements are classified into three dimensions: The first dimension is the concept category of an element. The second dimension is an element's status in the story. The third dimension indicates where an element appears in a picture book. Additionally, it revealed a young children's general search strategy: Children first use auditory elements that they hear from the adults during reading. After receiving error returns, they add visual elements that they see by themselves in picture books. The findings can not only help to understand young children's known-item search and reformulation strategies during searching but also provide theoretical support for the development of a picture book information organization schema in the search system.

In: Information processing and management. 52(2016) no.1, S.61-72.
Abstract: In recent years, there has been a rapid growth of user-generated data in collaborative tagging (a.k.a. folksonomy-based) systems due to the prevailing of Web 2.0 communities. To effectively assist users to find their desired resources, it is critical to understand user behaviors and preferences. Tag-based profile techniques, which model users and resources by a vector of relevant tags, are widely employed in folksonomy-based systems. This is mainly because that personalized search and recommendations can be facilitated by measuring relevance between user profiles and resource profiles. However, conventional measurements neglect the sentiment aspect of user-generated tags. In fact, tags can be very emotional and subjective, as users usually express their perceptions and feelings about the resources by tags. Therefore, it is necessary to take sentiment relevance into account into measurements. In this paper, we present a novel generic framework SenticRank to incorporate various sentiment information to various sentiment-based information for personalized search by user profiles and resource profiles. In this framework, content-based sentiment ranking and collaborative sentiment ranking methods are proposed to obtain sentiment-based personalized ranking. To the best of our knowledge, this is the first work of integrating sentiment information to address the problem of the personalized tag-based search in collaborative tagging systems. Moreover, we compare the proposed sentiment-based personalized search with baselines in the experiments, the results of which have verified the effectiveness of the proposed framework. In addition, we study the influences by popular sentiment dictionaries, and SenticNet is the most prominent knowledge base to boost the performance of personalized search in folksonomy.

3Xie, H.I.: Users' evaluation of digital libraries (DLs) : their uses, their criteria, and their assessment.
In: Information processing and management. 44(2008) no.3, S.1346-1373.
Abstract: Millions of dollars have been invested into the development of digital libraries. There are many unanswered questions regarding their evaluation, in particular, from users' perspectives. This study intends to investigate users' use, their criteria and their evaluation of the two selected digital libraries. Nineteen subjects were recruited to participate in the study. They were instructed to keep a diary for their use of the two digital libraries, rate the importance of digital library evaluation criteria, and evaluate the two digital libraries by applying their perceived important criteria. The results show patterns of users' use of digital libraries, their perceived important evaluation criteria, and the positive and negative aspects of digital libraries. Finally, the relationships between perceived importance of digital library evaluation criteria and actual evaluation of digital libraries and the relationships between use of digital libraries and evaluation of digital libraries as well as users' preference, experience and knowledge structure on digital library evaluation are further discussed.

4Xie, H.I.: Understanding human-work domain interaction : implications for the design of a corporate digital library.
In: Journal of the American Society for Information Science and Technology. 57(2006) no.1, S.128-143.
Abstract: The author applies the cognitive work analysis (CWA) approach to investigate human-work interaction in a corporate setting. This study reports the analysis of data collected from a Web survey, diaries, and telephone interviews. The results present characterizations of actors and the work domain; three dimensions for each of the four interactive activities involved in the human-work interaction and their relationships are identified. An enhanced model and its implications for the development of a corporate digital library are discussed.
5Rieh, S.Y. ; Xie, H.(I.): Analysis of multiple query reformulations on the web : the interactive information retrieval context.
In: Information processing and management. 42(2006) no.3, S.751-768.
Abstract: This study examines the facets and patterns of multiple Web query reformulations with a focus on reformulation sequences. Based on IR interaction models, it was presumed that query reformulation is the product of the interaction between the user and the IR system. Query reformulation also reflects the interplay between the surface and deeper levels of user interaction. Query logs were collected from a Web search engine through the selection of search sessions in which users submitted six or more unique queries per session. The final data set was composed of 313 search sessions. Three facets of query reformulation (content, format, and resource) as well as nine sub-facets were derived from the data. In addition, analysis of modification sequences identified eight distinct patterns: specified, generalized, parallel, building-block, dynamic, multitasking, recurrent, and format reformulation. Adapting Saracevic's stratified model, the authors develop a model of Web query reformulation based on the results of the study. The implications for Web search engine design are finally discussed and the functions of an interactive reformulation tool are suggested.
6Xie, H.I.: Patterns between interactive intentions and information-seeking strategies.
In: Information processing and management. 38(2002) no.1, S.55-77.
Abstract: In order to design information retrieval (IR) systems to support various information-seeking strategies across a variety of contexts, it is important to explore what leads to the selection of different types of information-seeking strategies. This study addresses the issue by investigating the relationships between users' information-seeking goals and their information-seeking behaviors. The particular focus of this study is to specify hierarchical levels of user goals, and to investigate the micro-level goal labeled "interactive intention" in relation to information-seeking strategies. A total of 40 users from four types of libraries were selected for this study, and the analysis illustrates how changes in interactive intentions are associated with changes of information-seeking strategies. The results present how eight types of interactive intentions, four types of entities, eight types of methods, and six types of resources constitute the patterns of interactive intentions and information-seeking strategies. The implications for IR system design are further discussed.

8Xie, H.I. ; Wolfram, D.: State digital library usability contributing organizational factors.
In: Journal of the American Society for Information Science and technology. 53(2002) no.13, S.1085-1097.
Abstract: In this issue Xie and Wolfram study the Wisconsin state digital library BadgerLink to determine the organizational factors that lead to different use requirements and the degree to which these are met, as well as impact on physical libraries. To this end, usage data from EBSCOhost and ProQuest logs for BadgerLink were analyzed, 313 Wisconsin libraries of all types were surveyed (76% response rate), and analyzed along with 81 responses to a voluntary web survey of end users. Heaviest users were K-12 schools and institutions of higher education. Heaviest use sites were the two largest state universities and the state's largest public library. Small libraries were infrequent users. Web survey respondents were mature working professionals. Sixty percent searched for specific information, but 46% reported browsing in subject areas. Libraries with dedicated Internet access reported more frequent usage than those with dial-up connection. Those who accessed from libraries reported more frequent use than those at work or at home. Libraries that trained end users reported more use, but the majority of the web survey respondents reported themselves as self-taught. Logs confirm reported subject interests. Three surrogates were requested for every full text document but full text availability is reported as the reason for use by 30% of users. Availability has led to the cancellation of subscriptions in many libraries that are important promoters of the service. A model will need to include interactions based upon the influence of each involved participant on the others. It will also need to include the extension of the activities of one participant to other participant organizations and the communication among these organizations.
9Xie, H.I.: Shifts of interactive intentions and information-seeking strategies in interactive information retrieval.
In: Journal of the American Society for Information Science. 51(2000) no.9, S.841-857.
Abstract: Research has demonstrated that people engage in multiple types of information-seeking strategies when using IR systems; unfortunately, current IR systems are designed to support only one type of information-seeking strategy: specifying queries. The limitation of existing IR systems calls for the need to investigate how to support users as they shift from one information-seeking strategy to another in their attemps to achieve their information-seeking goals. The focus of this study is on the in-depth investigation of shifts in the mico-level of user goals - 'interactive intention' and information-seeking strategies that users engage in within an information-seeking episode. 40 cases of library uses were selected from 4 different types of libraries for this study. The qualitative and quantitative analysis of the data identifies 4 types of shifts of interactive intentions and 3 types of information-seeking strategies. The results of the study are discussed to understand the nature of the interactive IR process, and to further suggest their implications for the design of adaptive IR systems

Abstract: Studies have indicated that various groups of intellectual property users are unaware of many aspects of copyright law and often do not understand that it applies to works in electronic forms, or are unconcerned with copyright restrictions. It is hypothesized that users would be more likely to conform to copyright law if a process could be developed that make it easier to access copyright management information on the Internet and in other electronic media. Before designing such a mechanism, the following research questions need to be addressed: 1) To what extent are users clear or concerned with obeying copyright law in the use of materials available in electronic formats? 2) Will users be more willing to comply with copyright law if copyright information is incorporated within electronic forms in a format that makes it easier to understand or easier to locate? 3) What amount of time are users willing to devote to locating copyright management information? and 4) What methods would users prefer to utilize in locating copyright management information? To address these questions a research instrument was developed and tested in a pilot study in which sixty students from two large higher public education institutions participated, 30 from New York City and 30 from Wisconsin. The instrument ascertained each participant's experience with electronic forms, the frequency with which they downloaded copyright materials, their level of concern regarding compliance with copyright law and their willingness to comply with copyright law if copyright management information was more effectively available. They were also asked to rank possible methods for locating copyright management information. Both qualitative and quantitative methods were employed to analyze the data. The results suggest that the participants would be more willing to comply with copyright law if copyright management information was easier to locate or to understand. The results also show that few users are willing to devote more than ten minutes to locating copyright management information. The study points to a need for an easy and rapid method to locate copyright management information within electronic forms and for increased user education about copyright law
