Abstract
There is a huge and ever increasing amount of data sources available on the Web, which provide content through programmatic interfaces. Unfortunately, such data sources are accessible only through programming and therefore it is difficult for non-technical users to take advantage of such enormous data assets. The need therefore arises for paradigms to let laypeople, i.e., users without expertise in programming, explore and compose data sources. This paper discusses mechanisms for data source exploration and integration, which emerged from a study where laypeople were involved in discussions to gather their requirements about accessing and composing services. The paper also describes the prototypes that we defined to respond to the requirements highlighted by end usersI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
