So we need to increase the ability to efficiently access this information. Text Classification is hard if we do it manually. So we need a tool that classifies text and images more accurately. In Existing system, users need to check various documents to find out similar documents. So the accuracy of related document is very less. It is very time consuming process. The proposed system is a recommendation system with maximum accuracy and minimum time. System recommends documents based on the users query. Also calculate the probability based on classification. Boosting based multi-graph classification technique is used by system to classify the documents. It provides most related documents to the user. System preprocesses the documents and finds the common author relation. System uses multi-graph and article ranking to find the most relevant documents.
Boosting is a machine learning meta-algorithm which reduces bias and variance in supervised learning. It is a family of machine learning. Boosting converts weak learners to strong learners. Weak learner classifier is less correlated with true classification. Strong learner classifier is more correlated with true classification. Boosting algorithms consist of learning weak classifiers and adding them strong classifier. The proposed system uses AdaBoost algorithm. AdaBoost is popular machine learning algorithm which adapt to the weak learners.
1.2 Graph Classification Multi-graph classification problem is viewed as a graph classification problem. In which objects are consider as bag of graphs. Classification of objects is based on the multiple graphs. It can be classified into following two categories: 1. Global Distance Based Approaches: This method is based on the similarities and correlations [2] between two graphs. One drawback of this method is, it is not clear which part of graph is more discriminative for differentiating graphs of different classes. 2. Local Sub graph Feature Based Approaches: This method is based on the frequency of most common sub graph selection which select frequently appearing sub graphs by using frequent sub graph mining methods. One drawback of this method is to handle large graph sets. To overcome this drawback, some boosting methods [3]–[6] is use sub graph feature as a weak classifier, including some other types of boosting methods [7], [8] for graph classification.
Key Words:-Multi-graph, Boosting, Feature vector citation, Common author relation, Article Ranking, TFIDF.
1. INTRODUCTION In today's era a user wants to search any topic then he/she will search on www by giving an input in text format. After searching, many times user won’t get the results because same text or words having same meaning. So due to that accuracy of getting correct results of query is less. And users have to search all the links which he gets. So it is very time consuming. We are going to implement a system which will reduce overhead of user of searching many pages and documents for single query. In the system user upload the document. Then system will perform preprocessing and text mining on data set. So the stop words are removed and important words get mined. According to that, searching performed. System calculates the probability of related documents and multi-graph classification (bMGC) [1] is done. Then system recommends the documents or articles which are closer to input. Users also get the probability of the documents which are more relevant for recommendation.
