Instance-based Schema Matching for Web Databases by Domain-specific Query Probing
In a Web database that dynamically provides information in response to user queries, two distinct schemas, interface schema (the schema users can query) and result schema (the schema users can browse), are presented to users. Each partially reflects the actual schema of the Web database. Most previous work only studied the problem of schema matching across query interfaces of Web databases. In ...
متن کاملParallel Probing of Web Databases for Top-k Query Processing
A “top-k query” specifies a set of preferred values for the attributes of a relation and expects as a result the k objects that are “closest” to the given preferences according to some distance function. In many web applications, the relation attributes are only available via probes to autonomous webaccessible sources. Probing these sources sequentially to process a top-k query is inefficient, ...
متن کاملQuery Architecture Expansion in Web Using Fuzzy Multi Domain Ontology
Due to the increasing web, there are many challenges to establish a general framework for data mining and retrieving structured data from the Web. Creating an ontology is a step towards solving this problem. The ontology raises the main entity and the concept of any data in data mining. In this paper, we tried to propose a method for applying the "meaning" of the search system, But the problem ...
متن کاملQuery Refinement for Domain-Specific Web Search
The expansion of the Internet and the number of its users has raised many new problems in information retrieval. The most common way to find information in the web is using web search engines. However, gathering information from the web is a difficult task for a novice user even if he uses the search engines. The user must have experience and skill to find the relevant pages from the large numb...
متن کاملQuery Interface Integrator For Domain Specific Hidden Web
Web is title admittance today mainly relies on search engines. A large amount of data is hidden in the databases behind the search interfaces referred to as “Hidden web”, which needs to be indexed so in order to serve user’s query. In this paper database and data mining techniques are used for query interface integration (QII). The query interface must resemble the look and feel of local interf...
