Flexible Queries to Semistructured Datasources: The WG-log Approach
نویسندگان
چکیده
A line of research is presented aimed at specifying both logical and navigational aspects of semi-structured data sources such as Web sites through the unifying notion of schema. Gracefully supporting schemata that are huge or subject to change, the WG-Log language allows for a uniform representation of queries and views, the latter expressing customized access structures to site information. A survey of related work and some directions for future research involving fuzzy query techniques are also outlined.

متن کاملUsing WG-Log to Represent Semistructured Data: The Example of OEM
In this paper we discuss the possibility to represent synthetically semistructured information via a loose notion of schema: we say that data are semistructured when, although some structure is present, it is not as strict, regular, or complete as the one required by the traditional database management systems. Our proposal is based on WG-Log, a graph based language for the representation of WW...

Metodologie e tecnologie per la gestione di dati e processi su reti Internet e Intranet Sommario In order to pose eeective queries to Web sites, some form of site data model must be implicitly or explicitly shared by users. In this paper we propose WG-log, a query language which allows the description of data manipulation primitives via (sets of) graph(s). The use of WG-log for queries allows g...
متن کاملNon-Materialized Object Views of Web Datasources
Web datasources are mostly textual and often provide fulltext search options to access data. However accessing Web sources filling forms, browsing and reading is tedious. Most users are used to access and manipulate data with a rich query language and expect to query Web datasources the same way. To satisfy users, we propose an approach based on a nonmaterialized object view of Web datasources....
متن کاملStructuring and Querying the Web throughGraph - Oriented
In order to pose eeective queries to Web sites, some form of site data model must be implicitly or explicitly shared by users. Many approaches try to compensate for the lack of such a common model by considering the hypertextual structure of Web sites; unfortunately, this structure has usually little to do with data semantics. In this paper a diierent technique is proposed that allows for both ...
