A tool for rapid development of WS-BPEL applications
No full textWe present BliteC, a software tool we have developed for supporting a rapid and easy development of WS-BPEL applications. BliteC translates service orchestrations written in Blite, a formal language inspired to but simpler than WS-BPEL, into executable WS-BPEL programs. We illustrate our approach by means of an example borrowed from the official specification of WS-BPEL

No full textRecent trends of Web-based data processing (e.g., service
mashups, Data-as-a-Service) call for techniques to collect
and process heterogeneous data from distributed sources in
a uniform way. In this paper we present WS-Aggregation, a
general purpose framework for aggregation of data exposed
as Web services. WS-Aggregation provides clients with a
single-site interface to execute multi-site queries. The framework
autonomously collects and processes the requested data
using a set of cooperative aggregator nodes. The query distribution
is configurable using strategies, e.g., QoS-based or
location-based. We introduce WAQL as a specialized query
language for Web service data aggregation that is based on
XQuery. 3-way querying is a possibility to optimize requests
by reducing the amount of data transferred between aggregator
nodes. AWeb-based graphical user interface facilitates
composing aggregation requests. Our performance evaluation,
which comprises aggregation scenarios with different
settings, shows the good scalability of WS-Aggregation
WS-GraphMatching
No full textSome emerging applications deal with graph data and relie on graph matching and mining. The service-oriented graph matching and mining tool has been required. In this demo we present the web service tool WS-GraphMatching which supports the efficient and visualized matching of polytrees, series-parallel graphs, and arbitrary graphs with bounded feedback vertex set. Its embedded matching algorithms take in account the similarity of vertex-to-vertex and graph structures, allowing path contraction, vertex deletion, and vertex insertions. It provides one-to-one matching queries as well as queries in batch modes including one-to-many matching mode and many-to-many matching mode. It can be used for predicting unknown structured information, comparing and finding conserved patterns, and resolving ambiguous identification of vertices.

Can models of author intention support quality assessment of content?
No full textAcademics seek to find, understand and critically review the work of other researchers through published scientific articles. In recent years, the volume of available information has significantly increased, partly due to technological advancements and partly due to pressures on academics to 'publish or perish'. This amount of papers presents a challenge not only for the peer-review process but also for readers, particularly inexperienced readers, to find publications of high quality. Whilst one might rely on citation or journal rankings to help guide this decision, this approach may not be completely reliable due to biased peer-review processes and the fact that the citation count of an article does not per se indicate its quality. Here, we analyse how expected author intentions in a Related Work section can be used to indicate its quality. We show that author intentions can predict the quality with reasonable accuracy and propose that similar approaches could be used in other sections to provide an overall picture of quality. This approach could be useful in supporting peer-review processes and for a reader in prioritising articles to read. © 2019 CEUR-WS. All rights reserved.Peer reviewe
Service-oriented models for audiovisual content storage
No full textWhat are the important topics to understand if involved with storage services to hold digital audiovisual content? This report takes a look at how content is created and moves into and out of storage; the storage service value networks and architectures found now and expected in the future; what sort of data transfer is expected to and from an audiovisual archive; what transfer protocols to use; and a summary of security and interface issues
Complex Event Processing Network Usage in WS-BPEL Processes
No full textBiznesa procesu pārvaldības sfērā ir parādījies jauns tirgus virziens, kas ir orientēts uz reāla laika biznesa procesu pārvaldību (RTBPM). No citas puses aktuāla sfēra ir komplekso notikumu apstrāde (angl.Complex Event Processing, CEP) ar CEP dziņiem, kas ir attīstījusies neatkarīgi no biznesa procesu pārvaldības. Diemžēl šobrīd CEP dziņi maz tiek izmantoti RTBPM realizācijai.
Autors paplašina CEP dziņa abstrakciju ar CEP tīklu, kas reprezentē notikumu apstrādes infrastruktūru daudzu sistēmu vidē. Darbā tiek sniegts uz standartiem balstīts CEP tīkla un WS-BPEL (angl. WS-Business Process Execution Language, izvēlēts biznesa procesu modelis) dziņa integrēts RTBPM risinājums, kā arī praktiska šī risinājuma realizācija. Galvenā risinājuma ideja ir ietvert CEP tīkla vaicājumus WSRF (angl. WS-Resource Framework) resursos, kas ļauj WS-BPEL procesiem saņemt notikumus izmantojot WSN (angl. WS-Notification).
Atslēgas vārdi: BPM, RTBPM, CEP, WSRF, WSN, integrācija.Recently a new market segment has emerged in business process management which is oriented towards real time business process management (RTBPM). On the other hand a topical area is Complex Event Processing (CEP) with CEP engines, which has developed independently of business process management. Unfortunately CEP engines are used rarely to implement RTBPM solutions.
Author extends the CEP engine abstraction with a CEP network which represents an infrastructure for event processing in a multi system environment. In this paper author provides CEP network and WS-BPEL (WS-Business Process Execution Language, selected business process model) engine integrated RTBPM solution as well a practical implementation of this solution. Main solution idea is to encapsulate CEP network queries in WSRF (WS-Resource Framework) resources which then allow WS-BPEL processes to receive events using WSN (WS-Notification).
