“…Such type of data also helped building the Yahoo ontology, which aims at accessing content on the Web with high quality. Also using metadata and ontologies, Barros et al, (1998) focus on enhancing Web searches by considering information that can better contextualize the queries. Information, in this case, is dynamically provided by the ontologies, which act as providers of potential related words.…”

This paper focuses on the usefulness of extracts of webpages in Brazilian Portuguese as the means to filter information for Web users to quickly and consistently judge the relevance of search engine results. ExtraWeb, an ontology-and HTML-based summarizer, has been built aiming at providing an alternative to query-biased extracts typically made available by Web search engines. An extrinsic evaluation of ExtraWeb was carried out under a controlled experiment that retrieves webpages in Portuguese and generates a set of extracts for an Internet user to evaluate. Only the relevance judgment of the extracts was assessed. Results show that the system is promising in helping users to filter relevant webpages.

“…The integration could provide a more complete query without the student needing to describe the context, thereby limiting the search results to courses that the student qualifies for enrolment. This type of integration is not commonly used despite its potential benefit [2]. Two key issues need to be addressed to improve the uptake: 1) the performance of such systems cannot be degraded, and 2) developers must find it easy to integrate these data sources into their applications.…”

Abstract. Database systems are an essential component in multi-tiered web applications. These applications increasingly interact with others using web services. In this paper, we describe and compare two architectures for integrating web services into web applications, and perform performance benchmarks using the Google web service. For one of the architectures we contribute a SOAP interface to the PostgreSQL Relational Database Management System, implemented as a user-defined function that allows developers to make service calls from within the database. We show that SQL can be used to easily query data provided by web services, and therefore as a way of accessing and using web services in a database-driven web application.
