“…Discussions of how to organize information for corporate or business interests were not common in the reviewed pre-web KO literature, but this has changed in the post-web era. Recent research has noted that some organizations have begun to build taxonomies in order to provide more efficient access to web-based business knowledge [9], while others have looked towards the creation of ontologies to help them manage corporate events -bringing together and organizing events from multiple sources [10]. Increasingly, the plethora of emails received by employees has also been seen as an issue that corporations must address.…”

Qualitative analyses were used to launch a preliminary exploration of the dominant knowledge organization (KO) trends in the pre-and post-web eras. Data for this study was assembled by searching the Library, Information Science, and Technology Abstracts database for articles that have used the term 'knowledge organization' or 'information organization' in their titles, abstracts, or descriptors. Taken as a whole, these preliminary results suggest that the content of the KO literature has shifted since the advent of the web. Although classic KO principles remain prominent throughout both eras, the presence of new content areas, such as metadata, denotes a shift in KO trends. In the pre-web era, the literature was related in large part to indexing and abstracting. In contrast, cataloging and classification issues dominate the landscape in the postweb era. The findings from this paper will be of particular use to those interested in learning about upcoming trends in the KO literature.

“…Complex event processing is supported by systems from various domains including active databases (e.g., Snoop [10]), and the Situation Manager Rule Language ( [1]), which is a general purpose language. Event management was also introduced in the area of business process management [14,2] and service-based systems [13,11,22]. An excellent introductory book to complex event processing is also available [27].…”

There is a growing need for the use of active systems, systems that act automatically based on events. In many cases, providing such active functionality requires materializing (inferring) the occurrence of relevant events. A widespread paradigm for enabling such materialization is Complex Event Processing (CEP), a rule based paradigm, which currently relies on domain experts to fully define the relevant rules. These experts need to provide the set of basic events which serves as input to the rule, their inter-relationships, and the parameters of the events for determining a new event materialization. While it is reasonable to expect that domain experts will be able to provide a partial rules specification, providing all the required details is a hard task, even for domain experts. Moreover, in many active systems, rules may change over time, due to the dynamic nature of the domain. Such changes complicate even further the specification task, as the expert must constantly update the rules. As a result, we seek additional support to the definition of rules, beyond expert opinion. This work presents a mechanism for automating both the initial definition of rules and the update of rules over time. This mechanism combines partial information provided by the domain expert with machine learning techniques, and is aimed at improving the accuracy of event specification and materialization. The proposed mechanism consists of two main repetitive stages, namely rule parameter prediction and rule parameter correction. The former is performed by updating the parameters using an available expert knowledge regarding the future changes of parameters. The latter stage utilizes expert feedback regarding the actual past occurrence of events and the events materialized by the CEP framework to tune rule parameters. We also include possible implementations for both stages, based on a statistical estimator and evaluate our outcome using a case study from the intrusion detection domain.

“…Regarding the representation of subscriptions, subscribers express their interests (or subscription patterns) using boolean expressions that include predicates on the context of the events in question (Cilia et al, 2005). These expressions include contextual information for the correct interpretation and matching of incoming events.…”

Enterprise application interactions based on events has been receiving increasing attention. It is based on the exchange of small pieces of data (called events) typically using the publish/subscribe interaction paradigm. Most pub/sub notification services assume a homogeneous namespace and do not support the interaction among heterogeneous event producers and consumers. In this paper we briefly describe the concept-based approach as a high-level dissemination mechanism for distributed and heterogeneous event-based applications. We focus on the design and implementation issues of such a mechanism and show how it can be integrated on research prototypes or products and platforms.
