A Method for Measuring Keywords Similarity by Applying Jaccard’s, N-Gram and Vector Space

Obviously, searching engines today have not sufficiently fulfilled the needs of users. Most of these searching engines are functioned using keywords query which are identical and relevant to conceptual search. This means that matched or successful searching results depend on how a user spells the keywords. Thus, the method for measuring keywords similarity between keywords query and index words is very crucial. This research focuses on keywords search. We have designed method for measuring keywords similarity with Jaccard’s, N-Gram, Vector space, Average (JNVA) and Jaccard’s, N-Gram, Length, Average (JNLA) by using hybrid method; a combination of Jaccard’s , N-Gram and Vector Space to make
