The nature of the information-rich environment of the 21st century has affected the ways in which students’ access information. Students no longer have to seek information; they acquire it passively through their everyday use of the Internet. This paper presents findings of a study involving the information encountering experiences of undergraduate students and the potential role of personal information collection, management, and retrieval in information literacy instruction. Undergraduate students enrolled in an information literacy course were surveyed regarding their experiences online with information encountering and personal information management. Survey questions were adopted from the information encountering scale developed by Wise & Erdelez (2012) and consisted of twelve questions focused on the noticing, stopping, examining, and capturing steps of the Information encountering model (Erdelez, 2004). The study indicates that the vast majority of the undergraduate students responding to the survey were frequently encountering unexpected information while online, but were not capturing this information for future use using built-in, web-based tools. While information literacy courses teach students to identify, seek, analyze, and use needed information, they do not prepare them to manage and retrieve unexpected information encountered while using the Internet.  相似文献

The purpose of this study is to investigate factors influencing students' perception of the credibility of scholarly information on the web. In addition to the four types of source credibility proposed by previous studies (presumed credibility, reputed credibility, surface credibility, and experienced credibility), this study shows that two other types of source credibility (verifiable credibility and cost-effort credibility) play a significant role in shaping students' perceptions of credibility. Circumstances that affect students' willingness to accept scholarly information on the web are identified. Implications for web system design are also discussed.  相似文献

This research focuses specifically on uncertainty and information seeking in a digital environment. In this research we argue that different types of uncertainty are associated with the information seeking process and that, with the proliferation of new and different search tools, sources and channels, uncertainty, positive/desirable or negative/undesirable, continues to be a significant factor in the search process. Users may feel uncertain at any stage of the information search and retrieval process and uncertainty may remain even after completion of the process resulting in what may be called persistent uncertainty. An online questionnaire was used to collect data from users in the higher education sector. There were three parts to the questionnaire focusing on: information seeking activities, information seeking problems, and access to specific information channels or sources. Quantitative analysis was carried out on the data collected through the online questionnaire. A total of 668 responses were returned from the chosen user categories of academic staff, research staff and research students. This research has shown that there are some information seeking activities and information seeking problems that are the most common causes of uncertainty among significant number of users from different disciplines, age, gender, ICT skills, etc. This is also the case with respect to access to and use of specific information sources/channels, although the degrees of uncertainty in relation are relatively small. Possible implications of this study and further research issues are indicated.  相似文献

Despite various models established to present the process of information encountering (IE), little research has been done on the stimulus that plays an essential role in attracting users’ attention and eliciting the subsequent behavioral responses during an IE process. This study was particularly interested in visual stimuli which are superior to textual ones in enhancing information processing and sensory experience. A diary study of IE was conducted in the context of micro-blogging services. They demonstrate the environmental characteristics conducive to IE and are especially abundant in visual stimuli. A total of 189 valid IE incidents triggered by visual stimuli on a representative micro-blogging service were collected with an online questionnaire created based on the critical incident technique (CIT) and analyzed both quantitatively and qualitatively. As found in this study, most of the visual stimuli triggering IE excluded text or motion, and their comprehensibility and novelty were both perceived to be high while humorousness much lower. The encountered micro-posts covered a wide range of topics and were published by different types of micro-bloggers. When interacting with the posts, the participants sometimes just examined their visual or textual content, but sometimes further captured the posts by liking, reposting, commenting, and following, etc. The significant results indicate that the visual stimuli excluding text and those with higher comprehensibility or humorousness were more likely to induce intense approach to the micro-posts. These findings inform micro-bloggers of the means of engaging the audience in intense interactions with their posts to gain persistent profit or reputation. The combination of diaries and the CIT is effective for data collection in IE research.  相似文献

This paper presents not only mycommunityinfo.ca (MCI) as an innovative World Wide Web (WWW)-based community information (CI) site, but also how its unique approach to facilitating online CI searching on the Web reveals through empirical data how people use such information and communication technologies (ICTs) to address their everyday information needs. The geographic focus for this study is on three communities in Southwestern Ontario. MCI collects unobtrusively query data that are logged daily from its own Web site, the Web sites of three municipal governments, and one municipal agency from this region. One year’s worth of these data was supplied to determine the types of CI that are sought through Web searching. A content analysis of a large purposive sample of all of MCI’s query data reveals more specific and diverse conceptual CI needs between and within communities than those reported in other studies employing different data collection methods. As a result, using a centralized approach to online CI access via the WWW by other CI providers such as the 211 network may be a disservice to its users. Additionally, the findings demonstrate how a thorough analysis of such data may improve the informational content and overall design of municipal government Web sites. The analysis of these data also has the potential of improving current CI taxonomies.  相似文献

We report a naturalistic interactive information retrieval (IIR) study of 18 ordinary users in the age of 20–25 who carry out everyday-life information seeking (ELIS) on the Internet with respect to the three types of information needs identified by Ingwersen (1986): the verificative information need (VIN), the conscious topical information need (CIN), and the muddled topical information need (MIN). The searches took place in the private homes of the users in order to ensure as realistic searching as possible. Ingwersen (1996) associates a given search behaviour to each of the three types of information needs, which are analytically deduced, but not yet empirically tested. Thus the objective of the study is to investigate whether empirical data does, or does not, conform to the predictions derived from the three types of information needs. The main conclusion is that the analytically deduced information search behaviour characteristics by Ingwersen are positively corroborated for this group of test participants who search the Internet as part of ELIS.  相似文献

The study focuses on the ways in which people define their source preferences in the context of seeking problem-specific information for non-work purposes. The conceptual framework draws on two major concepts, that is, information source horizon and information pathways. The former denotes the ways information sources are mapped in preference order in an imaginary field, while information pathways refers to the sequences in which sources placed on the information source horizon are actually used. The empirical part of the study draws on semi-structured interviews with 18 individuals active in environmental issues. Human sources and the Internet were preferred most strongly in seeking for problem-based information. The major source preferences were content of information, and availability and accessibility. Usability of information sources and user characteristics were mentioned less frequently as preference criteria. Typically, information pathways consisted of the use of 3–4 sources. On average, human and networked sources were favored in the early phases of information seeking. Printed media such as magazines and organizational sources were often used to complement information received from human sources and the Internet. However, the source preferences varied considerably, depending on the requirements of the problem at hand.  相似文献

Recent years have seen an explosion of interest in human information behavior in part attributable to the rapid development of the Internet and associated information technologies. Concomitantly there has been substantial growth in theoretic frames, research, and substantive models. However, these approaches have often been fragmentary, dependent on the goals of disparate disciplines that are interested in differing aspects of information behavior. They often have been rooted in the most rational of contexts, libraries, where individuals come with a defined problem, or information technology systems, that have their own inherent logic. Attempts to extend this work to everyday life contexts often run into disquieting findings related to the benefits of ignorance and the seeming irrationality of human information behavior. A broader view of our social world leads us to richer policy implications for our work. We live in exciting times, in an increasingly flattened world, where the ability for people to assimilate information they find into coherent personal strategies is perhaps the critical modern survival skill.  相似文献

This research contrasts two different conceptions, fields and pathways, of individual information behavior in context. These different approaches imply different relationships between actors and their information environments and, thus, encapsulate different views of the relationship between individual actions and contexts. We discuss these different theoretical views, then empirically compare and contrast them. The operationalization of these conceptions is based on different analytic treatments of the same raw data: a battery of three questions based on respondent’s unaided recall of the sources they would consult for information on inherited cancers, a particularly rich information seeking problem. These operationalizations are then analyzed in a nomological network of related concepts drawn from an omnibus survey of 882 adults. The results indicated four clusters for fields and 16 different pathways, indicating increased fragmentation of information environments, with different underlying logics and active ingredients, although the use of the Internet appears to be an emerging common theme. The analysis of the nomological network suggests that both approaches may have applications for particular problems. In the implications, we compare and contrast these approaches, discussing their significance for future methodological, analytical, and theoretical developments.  相似文献

The paper delineates and explains an emerging, but significant, form of digital information seeking behaviour among information consumers, which the authors have called ‘bouncing’. The evidence for this behaviour has emerged from five years of deep log analysis studies – an advanced form of transaction log analysis – of a wide range of users of digital information resources. Much of the evidence and discussion provided comes from the scholarly communication field. Two main bouncing metrics were applied in the log studies: site penetration, which is the number of items or pages viewed in a session, and return visits. The evidence shows that (1) a high proportion of people view just a few items or pages during a visit to a site and, (2) a high proportion of visitors either do not come back to the site or they did so infrequently. Typically those who penetrated a site least tended to return the least frequently. These people are termed ‘bouncers’. They bounce into the site and then bounce out again, presumably, to another site, as a high proportion of them do not appear to come back again. Possible explanations – negative and positive, for the form of behaviour are discussed.  相似文献

Many Web sites have begun allowing users to submit items to a collection and tag them with keywords. The folksonomies built from these tags are an interesting topic that has seen little empirical research. This study compared the search information retrieval (IR) performance of folksonomies from social bookmarking Web sites against search engines and subject directories. Thirty-four participants created 103 queries for various information needs. Results from each IR system were collected and participants judged relevance. Folksonomy search results overlapped with those from the other systems, and documents found by both search engines and folksonomies were significantly more likely to be judged relevant than those returned by any single IR system type. The search engines in the study had the highest precision and recall, but the folksonomies fared surprisingly well. Del.icio.us was statistically indistinguishable from the directories in many cases. Overall the directories were more precise than the folksonomies but they had similar recall scores. Better query handling may enhance folksonomy IR performance further. The folksonomies studied were promising, and may be able to improve Web search performance.  相似文献

This paper reports on a research project that investigated how library and information (LIS) professionals experience ethical dilemmas, with particular reference to the impact of new technologies, sources used to assist ethical decision-making, and the contribution case studies can make to ethical understanding and decision-making. Data was collected through interviews in Britain, Ireland and Australia with LIS professionals, educators, and representatives of professional bodies. The findings identify the main types of dilemma raised and discuss cases indicative of each type. They suggest that new technologies do not appear to change ethical principles but, when experienced in the workplace, substantially change the factors the professional has to evaluate. They also suggest that relevant codes of ethics are satisfactory on traditional library issues of access and confidentiality, but do not address the ethical challenges of current and potential digital environments. Professional associations appear more familiar with codes of ethics than practitioners although practitioners show high levels of ethical awareness, suggesting associations need to communicate more with their members and provide tools that are more useful in the workplace. Case studies are seen as a good way to educate and engage practitioners because of the complexity, conflicts and dynamism they can present.  相似文献

Recently, online recommendations have become a main channel for enterprise promotion; however, little evidence has been directed toward understanding the fitness of products information in the online recommendations context. The current study examines the fitness of recommended products information and budget of customers selves’ situation tries to find the key factors that buy exceed the recommended products in the online channels. Drawing upon the customer satisfaction index (CSI) and the price information seeking behavior (PISB) model, this paper proposes a research model and validates it in the context of recommendations from the well-known e-commerce websites from 342 participants. With Amos 18.0 this study finds that, in the online environment, the constructs of CSI are evaluated in online recommendations, in addition, finds the fitness of products information can be vital factor impact perceived quality, value, satisfaction, and buy extra. Moreover, the budget constraints of customers positively impact price comparison, and price comparisons negatively impact satisfactions. This research sheds light on the buy extra behavior in online recommendations and provides insights into the marketing promotion strategies in electronic markets.  相似文献

We identify and examine the assumption of information determinism that is commonplace in policy arenas: that mere access to the “right information” will precipitate desired actions. Our analysis focuses on implications of information determinism in three cases: California disaster response plans in the 1980s, an Indian development project in the 1990s, and an education project directed at the Global South in the 2000s. Our analyses shows that planning based on information deterministic assumptions tends to overlook the sociomaterial circumstances of information production and circulation, including how social structures and materiality shape information in practice. Further, they imbue what we call “information” with the agency to bring about change. While we do not deny that “information” can be useful, we argue that policy needs to move away from information deterministic thinking and its singular focus on information access to address the needs of marginalized and vulnerable populations.  相似文献

Using technology to facilitate learning in universities and other higher education institutions (HEIs) has become common practice due to its ability to reduce barriers related to time and space in traditional learning environments. However, current literature mostly focuses on the use of the technology and not on the use of the information it conveys. Also, very few studies focus on technology adoption in universities and HEIs in developing countries, especially those in Africa. Thus, we propose a model that explains the changing information behaviors of students in this digital age and the effect this has on their learning outcomes. We collected questionnaire data from 303 students and analyzed the data using structural equation modelling partial least squares (SEM-PLS). We found that our proposed model explains 60.2 % of student satisfaction, 24.2 % of academic performance, 24.1 % of information sharing, and 19.8 % of their information exchange behavior. This study confirms that the use of digital information and its antecedent factors have significant effects on the college experience of students. This has several implications for information systems research and practice, especially in the design and assessment of technology use in learning environments.  相似文献

Current awareness services are designed to keep users informed about recent developments based around user need profiles. In organisational settings, they may operate through both electronic and social interactions aimed at delivering information that is relevant, pertinent and current. Understanding these interactions can reveal the tensions in current awareness dissemination and help inform ways of making services more effective and efficient. We report an in-depth, observational study of electronic current awareness use within a large London law firm. The study found that selection, re-aggregation and forwarding of information by multiple actors gives rise to a complex sociotechnical distribution network. Knowledge management staff act as a layer of “intelligent filters” sensitive to complex, local information needs; their distribution decisions address multiple situational relevance factors in a situation fraught with information overload and restrictive time-pressures. Their decisions aim to optimise conflicting constraints of recall, precision and information quantity. Critical to this is the use of dynamic profile updates which propagate back through the network through formal and informal social interactions. This supports changes to situational relevance judgements and so allows the network to ‘self-tune’. These findings lead to design requirements, including that systems should support rapid assessment of information items against an individual’s interests; that it should be possible to organise information for different subsequent uses; and that there should be back-propagation from information consumers to providers, to tune the understanding of their information needs.  相似文献
