Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2014, Vol 16, Issue 5
Abstract
Abstract: Information retrieval is the process of retrieving all the relevant documents that satisfies the user query from large corpora. It is aimed to provide the relevant information and documents that matches the user query. Outcome of the several research results confirms that difficulties in information retrieval are matching the query with corpus. Consequently, the enhanced indexing technique named Document Index Graph (DIG) used for indexing document collection in order to match and retrieve information efficiently. Hence, an enhanced DIG has been constructed that stores all the stemmed sentences of documents in the graph. The words with same stem can be stored only once in DIG. This helps to reduce the size of the graph. The most frequently appearing words are planted into FP (Frequent Pattern) Tree. The FP-tree is a compact representation of all relevant frequently occurring information in a corpus. The enhanced FP tree with a table generates all types of possible term set which satisfy the minimum support. Information is retrieved with the help of FP-Tree and Document Index Graph.
