BPM News - Folge 3

Die BPM-Kolumne des EMISA-Forums berichtet über aktuelle Themen, Projekte und Veranstaltungen aus dem BPM-Umfeld. Schwerpunkt der vorliegenden Kolumne bildet das Thema Standardisierung von Prozessbeschreibungssprachen und -notationen im Allgemeinen und BPEL4WS (Business Process Execution Language for Web Services) im Speziellen. Hierzu liefert Jan Mendling von der Wirtschaftsuniversität Wien in aktuelles Schlagwort. Des weiteren erhalten Leser eine Zusammenfassung zweier im ersten Halbjahr 2006 veranstalteten Workshops zu den Themen „Flexibilität prozessorientierter Informationssysteme“ und „Kollaborative Prozesse“ sowie einen BPM Veranstaltungskalender für die 2. Jahreshälfte 2006

GRIDKIT: Pluggable overlay networks for Grid computing

A `second generation' approach to the provision of Grid middleware is now emerging which is built on service-oriented architecture and web services standards and technologies. However, advanced Grid applications have significant demands that are not addressed by present-day web services platforms. As one prime example, current platforms do not support the rich diversity of communication `interaction types' that are demanded by advanced applications (e.g. publish-subscribe, media streaming, peer-to-peer interaction). In the paper we describe the Gridkit middleware which augments the basic service-oriented architecture to address this particular deficiency. We particularly focus on the communications infrastructure support required to support multiple interaction types in a unified, principled and extensible manner-which we present in terms of the novel concept of pluggable overlay networks

Information Retrieval and Query Ranking of Unstructured Data in Dataspace using Vector Space Model

There is a vast amount of data is available on the web in the form of WebPages, on the clouds or in the repositories of any organization. All data are stored digitally by any companies, enterprises or any organization, these data may be text data, streamed data, images, Facebook data, Twitter data, Videos and other documents available digitally on the Internet related any areas like manufacturing, engineering, medical, etc. collectively called Dataspace. The data available over the internet may be structured data, unstructured or without any format. The storing mechanism is different for each organization but searching and retrieval of data should be easy from the user�s point, they are able to find the relevant information efficiently and accurate information that should be satisfied them, so there should be a proper model, search engine or interface for finding the information. Retrieving information from the Internet and large databases are quite difficult and time-consuming especially if such information is unstructured. Several algorithms and techniques have been developed in the area of data mining and information retrieval yet retrieving data from large databases continue to be problematic. In this paper, the Vector Space Model (VSM) technique of information retrieval is used, by using VSM model documents and queries can be represented as a vector, whose dimension is considered as terms to build the index represent the unstructured data. VSM is widely used for retrieving the documents and data due to its simplicity and efficiency work on a large number of datasets. VSM is based on term weighting on document vectors using three steps 1) First step is used to create indexes of the documents to retrieve the relevant data, 2) In the second step weighting of the indexed terms is used to retrieve the appropriate document for the end user, and (3) In the Finally steps the similarity measures is between documents to rank the documents relevant to the end user query using. The cosine measure is often used. We then found out that it is easier to retrieve data or information based on their similarity measures and produces a better and more efficient technique or model for information retrieval

A New Institutional Analysis of IFRS Adoption in Egypt: A Case Study of Loosely Coupled Rules and Routines

This paper examines the symbolic use of International Financial Reporting Standards (IFRS) in an Egyptian state-owned company (AQF Co.) that is partially privatised by drawing on new institutional sociology and its extensions. It explains how the ceremonial use of IFRS is shaped by the interplay between institutionalised accounting practices, conflicting institutions, power relations and the use of IT to institutionalizing accounting rules and routines. The research methodology is based on using an intensive case study. Data were collected from multiple sources, including unstructured and semi-structured interviews, direct and participative observations, discussions and documentary analysis. The findings revealed that the company faced conflicting institutional demands from outside. The Central Agency for Accountancy required the company to use the Uniform Accounting System (as a state-owned enterprise) and The Egyptian Capital Market Authority required the company to use IFRS (as a partially private sector company registered in the stock exchange). To meet these conflicting institutional demands, the company adopted loosely coupled accounting rules and routines and IT was used to institutionalizing existing Uniform Accounting System and preserving the status quo

Video résumés portrayed: findings and challenges

Recent technological developments and the increased use of internet-based applications have resulted in the emergence of so-called video résumés. This chapter first presents the characteristics of video résumés as a selection instrument by comparing the instrument with other, related selection tools, like the job interview. The chapter proceeds with a review of existing research on video résumés and ends with an agenda for future research
