Personal experience as social capital in online investor forums

Research demonstrates that information disseminated and circulated in online forums may have a significant impact on investors and on the securities market. Therefore, an understanding of that environment is critical. This research uses social capital theory as a framework for understanding how information exchange is facilitated in online investor forums. Specifically, it explores whether or not personal experience may generate social capital in the online environment. This work reports on the relationships between sharing personal experience and information sharing and use in three investor discussion forums. Four hundred forty threads containing 2405 posts were analyzed for this study. Thread starter posts and responses were quantified and coded for statements of personal experience. Citations to information sources were also measured. Results demonstrate that explicitly stating personal experience or lack of personal experience affects the quantity and quality of ensuing discussion and information exchange. Possible implications of this work on both the study of online investor forums and the study of social capital are discussed.     

State of the library and information science blogosphere after social networks boom: A metric approach

A metric analysis of blogs on library and information science (LIS) between November 2006 and June 2009 indexed on the Libworm search engine characterizes the community's behavior quantitatively. An analysis of 1108 personal and corporate blogs with a total of 275,103 posts is used to calculate survival rate, production (number of posts published), and visibility via such indicators as links received, Technorati authority, and Google's PagePank. Over the study period, there was a 52% decrease in the number of active blogs. Despite the drop in production over this period, the average number of posts per blog remained constant (14 per month). The most representative blogs in the discipline are identified. The emergence of such platforms as Facebook and Twitter seems to have meant that both personal and corporate blogs have lost some of their prominence.     

Putting the pieces together: endometriosis blogs,cognitive authority,and collaborative information behavior

Objective:

A discourse analysis was conducted of peer-written blogs about the chronic illness endometriosis to understand how bloggers present information sources and make cases for and against the authority of those sources.

Methods:

Eleven blogs that were authored by endometriosis patients and focused exclusively or primarily on the authors'' experiences with endometriosis were selected. After selecting segments in which the bloggers invoked forms of knowledge and sources of evidence, the text was discursively analyzed to reveal how bloggers establish and dispute the authority of the sources they invoke.

Results:

When discussing and refuting authority, the bloggers invoked many sources of evidence, including experiential, peer-provided, biomedical, and intuitive ones. Additionally, they made and disputed claims of cognitive authority via two interpretive repertoires: a concern about the role and interests of the pharmaceutical industry and an understanding of endometriosis as extremely idiosyncratic. Affective authority of information sources was also identified, which presented as social context, situational similarity, or aesthetic or spiritual factors.

Conclusions:

Endometriosis patients may find informational value in blogs, especially for affective support and epistemic experience. Traditional notions of authority might need to be revised for the online environment. Guidelines for evaluating the authority of consumer health information, informed by established readers'' advisory practices, are suggested.

Highlights

• Endometriosis patients who blog about the illness may determine authority of information sources through both cognitive and affective methods.

Implications

• Because patients with chronic illnesses might have different authority criteria than medical librarians do, it could be useful to carefully incorporate electronic patient discussion forums, medical blogs written by laypeople, and other nontraditionally authoritative resources into consumer health information selection policies. Standard biomedical resources are certainly important to recommend to consumers, but they do not convey the complete picture of a chronic illness and its related experience.
• Patients with chronic illnesses and caregivers can benefit from sources such as blogs and online discussion lists that provide social and emotional support as well as accounts of “lived experience.”
• An understanding of the patient''s potential epistemological community can make the librarian''s recommendations more appropriate for the individual user.

     

Social software as support in hybrid learning environments: The value of the blog as a tool for reflective learning and peer support

This article reports on an investigation of blog technology's potential for encouraging interaction between students, and its consequences in terms of peer learning and peer support, on a module of an accredited library and information science (LIS) degree program. The findings consider the treatment of blogs in the domain of LIS with particular reference to educational settings. Content analysis revealed that blogs offer comparable and additional benefits to other projects designed to encourage reflective engagement with teaching material, such as learning journals. Most notable is the level of shared peer support evident in the online discussions between class members. The findings of this study are of particular interest to LIS educators who seek to develop their consideration of blogs in the classroom; blogs may be seen as learning tools in their own right and not simply an option for providing information online.     

Knowledge Management: A Tool for Implementing the Digital Economy

The issues of application of knowledge-management technologies in modern economic conditions are stated. The aspects of digitalization of the economy, including those at the corporate level, are considered. The concept of “knowledge management” is analyzed from the point of view of foreign researchers; it is noted that knowledge has become an important intangible asset and a factor of competitiveness. The main results of knowledge customization (knowledge maps, knowledge packages, resource catalogs, forums and chats, practice communities, storytelling, corporate blogs, and a bank of ideas) are distinguished. Application of ontological models and gamification in order to involve staff in the dissemination and exchange of knowledge is shown. The roles of human and information technologies in knowledge management are compared.     

Hot Diggity Blog: A Cluster Analysis Examining Motivations and Other Factors for Why People Judge Different Types of Blogs as Credible

Using two-step cluster analysis this study identifies four groups of users who deem seven types of blogs (general information, media/journalism, war, military, political, corporate, and personal blogs) as highly credible. The four groups are each motivated to turn to blogs for many of the same reasons; however, some differences emerged among the groups. In addition, the four user clusters differ on demographic and political characteristics.     

What is Slow Journalism?

In an era of fast and instantaneous journalism and concerns about the deleterious effects of speed, it can be easy to lose sight of the other kinds of journalism being practiced, other temporalities for its production. There has been little scholarly work on slow journalism, so the first aim of this article is, if not to define, then at least to describe some key characteristics of what slow journalism might be. It will look at how the term has been used on blogs, websites, public forums, and in the minimal scholarly literature available. It will also explore some examples by producers who identify with the term to see what slow journalism looks like in practice. The proliferation of independent journalism using Slow as a way of thinking about production suggests that we are witnessing a new alternative emerging in the mediascape.     

A pessimistic view of AM radio

As the host of a radio show, a radio jock is often required or elects to post supplemental online writing or blogs as a way to bridge the gap between on-air personality and online interactive individual. However, to this date there is little or no research around the wants and motivations for an on-air personality to disclose information via an online blog. This article looks into the connection between digital biography of the modern-day radio jock as supplemental show information and personality development. Findings conclude that commercial radio hosts use blogs primarily for monetary gain which is different from their campus/community and public radio counterparts who blog in order to generate and engage with listeners. The article concludes with recommendations for radio stations and jocks on how best to implement blogs and match goals and motivations for their use.     

Estimating the diffusion models of crisis information in micro blog

The study tries to construct the diffusion models of crisis information in micro blog. We propose three information release patterns in micro blog according to the duration of crisis information released, namely concentrated release, continuous release, and pulse release. Based on Logistic function, three respective diffusion models are constructed. We choose three crisis events to test the diffusion models using the variables of the number of micro blogs with the crisis information (NMCI) and the increment of NMCI. The estimate results show that the diffusion of crisis information in micro blogs can be described by Logistic function, and the growth curve of NMCI is S-shaped.

Trends in online networking among South Korean politicians — A mixed-method approach

In recent years, as information technologies have grown in sophistication and become more fully integrated into daily lifestyles, a general expectation has arisen that the internet has the potential to reconfigure social and political relationships, and to create new political configurations. Blogging, in particular, has been seen to have significant potential to merge the public and the personal in new ways, potentially altering the nature of politics, particularly in nations where political processes are formalistic and highly regulated. As an example, politicians who blog have developed a new approach to communicating with their constituencies, in that the private thoughts of the political actor are expressed in a relatively unmediated environment. This study, which examines trends in blog linkages among Assembly members in Korea, provides a longitudinal analysis of blog linkages in order to assess the long term implications of new media technologies in Korean society and politics. The data were gathered from the blogs of Korea's National Assembly members for 2005 and 2006. An analysis of these links indicates that, indeed, there is an increased use of blogs among National Assembly members. However, it seems that over time, the network becomes sparser, less integrated, and more decentralized. This study also suggests that offline imperatives for political organization figure prominently in the motives of establishing online linkages to other political blogs.     

Blog feed search with a post index

User generated content forms an important domain for mining knowledge. In this paper, we address the task of blog feed search: to find blogs that are principally devoted to a given topic, as opposed to blogs that merely happen to mention the topic in passing. The large number of blogs makes the blogosphere a challenging domain, both in terms of effectiveness and of storage and retrieval efficiency. We examine the effectiveness of an approach to blog feed search that is based on individual posts as indexing units (instead of full blogs). Working in the setting of a probabilistic language modeling approach to information retrieval, we model the blog feed search task by aggregating over a blogger’s posts to collect evidence of relevance to the topic and persistence of interest in the topic. This approach achieves state-of-the-art performance in terms of effectiveness. We then introduce a two-stage model where a pre-selection of candidate blogs is followed by a ranking step. The model integrates aggressive pruning techniques as well as very lean representations of the contents of blog posts, resulting in substantial gains in efficiency while maintaining effectiveness at a very competitive level.     

THE BLOGGING BBC

Blogging has shifted from an activity largely taking place outside established media to a practice appropriated by professional journalists. This study explores how BBC News has incorporated blogging in its journalism, looking at the internal debates that led to the adoption of blogs and charting how they became a core part of the corporation's news output. Using a case study approach, it examines the impact of blogging on BBC editorial values and considers how journalists have sought to maintain their authority in a digital media environment by integrating a new form of journalism within existing norms and practices. The BBC offers a unique case study as its long-standing editorial values of accuracy, impartiality and fairness appear at odds with the notion of blogs as immediate, uncensored and unmediated. The research reveals that blogs emerged initially as an activity peripheral to the main newsgathering functions of the organisation and were rapidly transformed into key mechanisms for communicating analysis and commentary to the public. It contends that, for now, blogging has had a greater impact on the style, rather than substance, of BBC journalism. While the systems whereby journalists deliver information have evolved, the attitudes and approaches have, so far, remained relatively static.     

The Structure of the Biblioblogosphere: An Examination of the Linking Practices of Institutional and Personal Library Blogs

The biblioblogosphere is comprised of the institutional publication of blogs of libraries and the personal, professionally-oriented publication of blogs by librarians. Since introduction of this neologism in 2004, a number of researchers have examined this particular class of bloggers and blogging. However, there is limited investigation into the structure and connectivity of blogs within the biblioblogosphere. This article reports a study of interlinkage patterns within a sample of 1,604 biblioblogs. Findings suggest the biblioblogosphere conforms to the locally dense, globally sparse structure of blog networks established by previous studies of other blog types. The majority of blogs within the sample did not link to any other sampled blog. Those that did tended to cluster according to library type, blog subject, or geographical proximity. About one-third of the interlinked blogs were located within a single, massive component (that is, a networked group of blogs), while the rest were in smaller networks of two or three nodes. Personal biblioblogs, characterized as blogs published by individuals independently of an institution, are more likely to be located within a more densely populated network than institutional blogs. These findings indicate that “personal-professional” bibliobloggers are actively shaping the structure of the library blogosphere, while institutional blogs demonstrate much less overall connectivity.     

Librarians and information scientists in the blogosphere: An exploratory analysis

Blogging, though a relatively new phenomenon, has already gained greatly in popularity, and blogs have become an essential information channel in the Web 2.0 information world. Research into 30 topic-oriented blogs dealing with librarianship and information science, focusing specifically on tagging and folksonomies, was conducted over a period of two months. The purpose of the analysis was to describe and classify the LIS blogosphere, with the purpose of understanding the tagging patterns of librarian and information scientist bloggers and the nature of the folksonomies they form. Findings indicate that professional LIS blogs reflect the most up-to-date interests of LIS professionals as well as bloggers' personal lives and experiences. Content analysis reveals that the tag schemes generated by users contain their own internal logic and order.
