In this paper, we present our experiences in analyzing Twitter data. The analysis has shown that information diffuses over time through the Twitter network in certain patterns. Furthermore, it has shown those friend relationships significantly influence the information propagation speed on Twitter. Since it was launched in 2006, the microblogging s...

Given the increasing amounts of textual data published online and our inability to reliably identify a person by their writing style, impersonation in the context of social media applications becomes a real-world problem. This work explores how deep learning and metric learning techniques can be applied to the challenge of authorship verification—g...

This paper outlines work on the detection of anomalous behaviour in Online Social Networks (OSNs). We present various auto- mated techniques for identifying a ‘prodigious’ segment within a tweet, and consider tweets which are unusual because of writing style, posting sequence, or engagement level. We evaluate the mechanism by running extensive expe...

In order to create an effective article, having great content is essential. However, to achieve this, the writer needs to target a specific audience. A target audience refers to a group of readers that a writer intends to reach with his content. Defining a target audience is substantial because it has a direct effect on adjusting writing style and...

In recent years, blogs have become a very popular way to publish information, express opinions and hold discussions. Hence researchers and industry have interest in analyzing the blogosphere. Due to the increasing diversity of blog usage, the initial categorization into web genres is the first necessary step before any analyses. In this research, w...

Image search and recommendation engines try to extract relevant images for a user's information need. Existing approaches use manual tags of networks like Flickr or the surrounding webpages to create context to foster the search. Pinterest as a new upcoming social bookmarking service allows us to gain more context for an image than before. By using...

The BLOGINTELLIGENCE portal1 is the central hub for every tool, functionality and overall service presented in this book (see Fig. 14.1). Its design and content was carefully analyzed during previous research and ultimately realized to provide both an appealing user interface and the greatest level of usability possible for potential users when exp...

The Internet is not the first innovation which people have expected to lead to an enhanced sense of togetherness, understanding and even world peace. After the establishment of the first stable telegraphic connection, both radio and television have subsequently been supercharged with such utopian expectations, only to be rapidly demystified thereaf...

Successful enterprises attribute part of their success to effective internal communication which most employees would describe as direct and open communication with their management. These internal open channels of communication create an atmosphere of respect where co-worker and manager-employee relationships can flourish, keep employees intereste...

Our main goal is to show new ways and means to extract reliable and valuable knowledge of the blogosphere. Following an abstract view of the blogosphere from two different angles, we dive deeper into the diverse varieties of blogs and introduce some interesting ones. Then, we continue our journey by collecting requirements for retrieving new knowle...

We know that single weblogs are embedded into a complex superstructure known as the blogosphere. However, the absence of any centralized control, usually regarded as the blogosphere’s best feature, is its major shortcoming in this context: Aggregating and analyzing this vast pool of unstructured information in one central framework has seemed to be...

Social networks, especially weblogs, have been growing dramatically over the past years in the World Wide Web, making them a valuable source of information. As the amount of information exponentially grows, current research focuses on the meaningful and easy-to-use presentation of this massive amount of interconnected data, making it feasible to na...

The analysis of data generated within and from the blogosphere’s network can be insightful for numerous reasons and for a high diversity of interest groups. As noted in previous chapters, the blogosphere represents a part of the WWW that dynamically evolves and functions according to its own rules. These different characteristics are the foremost r...

To deal with the blogosphere in general requires a deep understanding of its smallest entities, individual weblogs, including their technical features and specifications. This knowledge (refer to Chap. 2) would remain entirely abstract if not tested under real conditions. On the basis of five different blog projects presented in the following chapt...

By applying well supported theories which have been generally accepted in business and technology literature, such as the notions of Disruptive Technologies or Power Laws on the underlying dynamics and regularities of the blogosphere, this chapter explains the phenomena of weblogging as a whole. It examines why blogging was able to experience such...

In the blogosphere, the continent Ego-blog refers to blogs that contain personal posts about the blogger’s daily life. Bloggers share their life experiences and knowledge of an enormous range of subjects. This category represents the archetype of blogs and the example chosen to illustrate the characteristics of this category, svenblogt.de (see Fig....

This chapter provides a comprehensive overview about weblogs as standalone entities. In particular, we discuss characteristic features of blogging software in general, its most important technical built-in features, as well as fundamental hosting issues. Also, this chapter presents a comprehensive review of prior weblog research by constructing an...

In Chap. 12 the general set of analysis techniques required to understand the blogosphere were discussed. This chapter presents one of two detailed analysis concepts in more detail. Each concept can be seen as an independent extension of the BLOGINTELLIGENCE platform that uses the existing crawler and analysis techniques.

Edu-blogs are blogs that serve the education of an individual or group. An Edu-blog can have one or multiple authors and can be used as a resource for learning material, a discussion forum, or an assessment tool for a student or teacher. To better understand modern learning techniques the features of Massive Open Online Courses (MOOCs) will be desc...

This chapter focuses on the discussion about how the data collected by the crawler (refer to Chap. 11) can and should be analyzed to extract, exploit and represent meaningful knowledge and to leverage content- and context-related structures and dynamics of partial blogospheres. There is a multitude of data analyzers that could process the informati...

The general set of analysis techniques required to understand the blogosphere have already been described earlier in Chap. 12 Here we turn to more detailed anaylsis concepts and in a similar way to the trend analysis concepts described above in Chap. 15, each of these can be seen as an independent extension of the BLOGINTELLIGENCE platform that use...

The massive adoption of social media has provided new ways for individuals to express their opinions online. The blogosphere, an inherent part of this trend, contains a vast array of information about a variety of topics. It functions as a huge think tank creating an enormous and ever changing archive of open source intelligence. Mining and modelin...

Current web mining approaches use massive amounts of commodity hardware and processing time to leverage analytics for today’s web. For a seamless application interaction, those approaches have to use pre-aggregated results and indexes to circumvent the slow processing on their data stores e.g. relational databases or document stores. The upcoming t...

Information about upcoming trends is a valuable knowledge for both, companies and individuals. Detecting trends for a certain topic is of special interest. According to the latest information over 200 million blogs exist in the World Wide Web. Hence, every day millions of posts are published. These blogs contain an enormous think tank of open-sourc...

Current ranking algorithms, such as PageRank, Technorati authority, and BI-Impact, favor blogs that report on a diversity of topics since those attract a large audience and thus more visitors, links, and comments. On the other side, niche blogs with a very specific topic only attract a small audience and thus have only a small reach. This results i...

Current blog search engines use rankings, such as BIImpact or B2Rank, focusing on the link structure and thereat criteria externally extracted for blogs. A good, but due to the unavailability, not often used criteria is the visitor engagement. This metric can leverage the quality of a ranking extremely. For this reason, we propose to gather visitor...

Since every day millions of posts are published inside the blogosphere a huge collection of web documents develops. Clustering this ever-changing collection is a very time consuming task. Therefore some certain challenges has to be accomplished because a clustering cannot be executed from scratch all the time. The presented fuzzy, incremental and h...

Today's number of weblogs is higher than ever before and still growing. These blogs are interconnected by numerous links and other diverse connections, generating a series of notable patterns. Weblogs are not isolated and highly connected with other social networks like Facebook and Twitter. Thus, we analyze the references and investigate methods t...
