Data mining for XML query-answering support(2012)

Abstract:

Extracting information from semi structured documents is a very hard task, and is going to become more and more critical as the amount of digital information available on the internet grows. Indeed, documents are often so large that the dataset returned as answer to a query may be too big to convey interpretable knowledge. In this work we describe an approach based on Tree-based Association Rules (TARs) mined rules, which provide approximate, in tensional information on both the structure and the contents of XML documents, and can be stored in XML format as well. This mined knowledge is later used to provide: (i) a concise idea – the gist – of both the structure and the content of the XML document and (ii) quick, approximate answers to queries. In this work we focus on the second feature. A prototype system and experimental results demonstrate the effectiveness of the approach.

Objective

            This project provides a method for deriving in tensional Knowledge from XML documents in the form of TARs, and then storing these TARs as an alternative, synthetic dataset to be queried for providing quick and summarized answers.

Existing System

            Extracting information from semi structured documents is a very hard task, and is going to become more and more critical as the amount of digital information available on the internet grows. Indeed, documents are often so large that the dataset returned as answer to a query may be too big to convey interpretable knowledge.

Proposed system

            In this work we describe an approach based on Tree-based Association Rules (TARs) minedrules, which provide approximate, in tensional information on both the structure and the contents of XML documents, and can be stored in XML format as well.

Modules:

1. Admin       

2. User

3. XmlQuery Answering

Admin:

Admin maintains the total information about the hole application.

Admin maintain the data in XML format only.

User:

user search queries and he got the reply in xml format.

XmlQuery Answering:

In this project user search the information in  semi structure document.he got reply in xml format only.
