Abstract While Web Question Answering System (WQAS) has made great progress in Internet currently, a major limitation of the information sources that current WQASs are using is limited to static page texts. Content information that many users-are interested in, is provided dynamically to Web through programs. Web services are becoming the dominant forms of such sorts of programs. In this paper, a novel model is proposed to address the problem of natural language answering based Web services. The expansions of OWL-S are used to describe the services, and predicate tuples retrieved from questions are matched to the services by PROLOG reasoning. To plan the services, SHOP2 planner is introduced in our architecture, which adopts a semantic Web for content modeling, logic grammar for question parsing, and Hierarchical Task Network (HTN) for user query problem solving. A case study in e-Tourism domain is investigated, which implements dynamic packaging for tourism products.

The I\O file system Read\Write operations are considered the most significant characteristics. Where, many researchers focus on their works on how to decrease the response time of I\O file system read\write operations. However, most articles concentrate on how to read\write content of the file in parallelism manner. Here in this paper, the author considers the parallelizing Read\Write whole file bytes not only its contents. A case study has been applied in order to make the idea more clear. It talks about two techniques of uploading\downloading files via Web Service. The first one is a traditional way where the files uploaded and downloaded serially. While the second one is uploaded\ downloaded files using Java thread in order to simulate parallelism technique. Java Netbeans 8.0.2 have been used as a programming environment to implement the Download\Upload files through Web Services. Validation results are also presented via using Mat-lab platform as benchmarks. The visualized figures of validation results are clearly clarifying that the second technique shows better response time in comparison to the traditional way.

The conversion of web services to semantic web comes the opportunity to automate various tasks. OWL-S plays a key role in describing web services behaviour. While ontology-based semantics given to OWL-S is structural rather than behaviourally oriented, we cannot automate an essential task in this field, verification. In this article, the mapping of OWL-S process model to Timed automata is investigated, which is a suitable formalism for real time systems modeling and automatic verification. Hence, this has led to not only enabling automatic verification but also covering problems related to automated verification of temporal quantitative properties as bounded liveness property. As a starting point, the OWL-S and sub entry of time ontologies for describing the timed behaviour of services has been chosen. A defined set of mapping rules is used to automatically encode control constructs defined in OWL-S and temporal information into timed automata. Also, it is shown how a Uppaal checker is used to check required properties formulated in TCTL. Finally, an EClinic case study is used to illustrate the technique.

Measuring Machine

As machines have become more intelligent, there has been a renewed interest in methods for measuring their intelligence. A common approach is to propose tasks for which a human excels, but one which machines find difficult. However, an ideal task should also be easy to evaluate and not be easily gameable. We begin with a case study exploring the recently popular task of image captioning and its limitations as a task for measuring machine intelligence. An alternative and more promising task is Visual Question Answering that tests a machine’s ability to reason about language and vision. We describe a dataset unprecedented in size created for the task that contains over 760,000 human generated questions about images. Using around 10 million human generated answers, machines may be easily evaluated.

Integration Architecture

Several systems integration proposals have been suggested over the years. However these proposals have mainly focused on data integration, not allowing users to take advantage of services offered by Web portals. Most of the mentioned proposals only provide a set of design principles to build integrated systems and lack in suggesting a systematic way of how to develop systems based on the integration architecture they propose. In previous work we have developed PISA (Web Portal Integration Architecture)—a Web portal integration architecture for data and services—and MIDAS-S, a methodological approach for the development of integrated Web portals, built according to PISA. This work shows, by means of a case study, how both proposals fit together integrating Web portals.

A framework is proposed that creates, uses, communicates, and distributes information whose organizational dynamics allow it to perform a distributed cooperative enterprise in public environments even over open source systems. The approach assumes Web services as the enacting paradigm, possibly over a grid, to formalize interaction as cooperative services on various computational nodes of a network. A framework is thus proposed that defines the responsibility of e-nodes in offering services and the set of rules under which each service can be accessed by e-nodes through service invocation. By discussing a case study, the chapter will detail how specific classes of interactions can be mapped into a serviceoriented model whose implementation will be carried out in a prototypical public environment.
