There exists a wide set of techniques to perform keyword-based search over relational databases but all of them match the keywords in the users’ queries to elements of the databases to be queried as first step. The matching process is a time-consuming and complex task. So, improving the performance of this task is a key issue to improve the keyword based search on relational data sources. In th...

Link creation in most existing hypertext / hypermedia products is a time consuming task. Microcosm is an open hypermedia system, in which various dynamic techniques have been used to attempt to ease the task of linking large bodies of information. This paper introduces the Microcosm model, and focuses on a technique for using computational power for dynamically creating links, known as retrieva...

It is a time consuming and difficult task for an individual, a group, or an organization to classify large collections of documents under a content-driven taxonomy. In this paper, we outline an approach for building a system which makes the classification process the responsibility of the author of the document, thus allowing the author to explain classifications and verify (or correct) automat...

Prediction of the quality attributes of software architectures requires technologies that enable the application of analytic theories to component models. However, available analytic techniques generally operate on formal models specified in notations that cannot flexibly and intuitively capture the architectures of large-scale distributed systems. The construction of model interpreters that tr...
