Index Weight Decision Technique for Search Reliable Documents

Search engine requirements increase as Internet use increases. Various types of forms must be requiring different search techniques. In case of academic writing (theses or professional scientific publications), quoted data from other documents must be appropriately handled. The occurrence of keywords in referenced documents, quoted in many documents in common, each highly weighted, attributes a disproportionately high weight to that keyword in the document. The more often a document is quoted, the more reliable the common portions of the referenced documents are ascribed to be. An algorithmic method of numerically ranking the importance of the pages is important to the search techniques. The quoted relations are sampled in the list of referenced documents and the statistics of the quoted relations were calculated. The technique renewing the keyword weight of referenced documents reflects the keyword weights of the quoted documents.
