Visual Programming of Web Data Aggregation Applications

Most of the information needs today can be satisfied by searching and browsing the Web. However, repetitive tasks such as monitoring information on Web sites should be done automatically on behalf of the user. Likewise, important events such as new information available on a monitored Web site should be actively reported to the user. These requirements can be met by building Web aggregation applications that distill required data from Web pages. Building such applications from scratch is a cumbersome and error prone task. Application programmers need to program functionalities such as Web navigation and page retrieval, content extraction, and result aggregation. In this paper we will present a fully visual development environment for Web data aggregation applications, the Lixto Transformation Server (TS). We will also demonstrate how this environment can be used to build services for personalized information channels. Users can subscribe such services to receive information on variou...
