Four papers are included in this issue. The first paper “Mining and visualising information from RSS feeds: a case study” by Martin O’Shea and Mark Levene presents two distinct technologies which employ the semi-structured nature of RSS to allow users to mine information directly from raw “really simple syndication” or “Rich site summary” (RSS) feeds: occurrence mining focuses on counting occurrences of text of interest in feeds, whilst value mining is aimed at mining more structured ticker tape numeric data. Authors describe both technologies and their implementation in an experiment, where 35 students were required to mine small numbers of RSS feeds and to visualise the data mined. The experiment also used a logging system, called the diary, to record data and metadata about user behaviour.

The second paper “An experimental system for measuring the credibility of news content in Twitter” by Hend S. Al-Khalifa and Rasha M. Al-Eidan proposes a system to measure the credibility of news content published in Twitter. The system uses two approaches to assign credibility levels (low, high and average) to each tweet. The first approach is based on the similarity between Twitter posts (tweets) and authentic (i.e. verified) news sources. The second approach is based on the similarity with verified news sources in addition to a set of proposed features. The evaluations of the two approaches showed that assigning credibility levels to Twitter tweets for the first approach has a higher precision and recall. Additional experiments showed that the linking feature has its impact on the second approach results.

In order to understand where related information may be found and how it may be explored by users, the third paper “Exploring web neighbours in exploratory search” by Kemal Efe, Alp Asutay and Arun Lakhotia, proposes tools and methods for displaying and exploring the graph neighbourhood of any selected item in the search results list. Earlier research provides sufficient evidence that web graph neighbourhoods of returned search results may contain documents related to users’ intended search topic. However, in the literature, no interface mechanisms have been presented to enable exploration of these neighbourhoods by users.

The last paper in this issue “Managing failures in web services atomic commitment protocols” by Juha Puustjärvi presents the Reliable WS-AtomicTransaction protocol, and illustrates its implementation by exploiting WS-Coordination, which describes an extensible framework for providing protocols that coordinate the actions of distributed applications. WS-ReliableMessaging specification describes a protocol that allows messages to be delivered reliably between distributed applications in the presence of software component, system, or network failures. The paper also presents the ontology of the log, which is maintained by the Reliable WS-AtomicTransaction protocol. The otology is presented in a graphical form and in OWL.
