FUZZY DOCUMENT REPRESENTATION FOR SEARCH DIVERSIFICATION

Fuzzy document representationinvolves transforming the unstructured data into numerical vectors. Such a representation is more useful for text classification and document clustering. The proposed Fuzzy Conceptualization Model (FCM) performs conceptualization and provides a better data representation model on the basis of semantic relatedness and similarity between terms in a word corpus. Word embedding is used to hold the semantically related words in a concept cluster. The concept clusters are inferred and vectored forthe given corpus to hold the data in a multidimensional space. FCM determines the fuzzy membership value of a base term by calculating the affinity score between its corresponding word embedding and other word embeddings. A weighing scheme isused to distinguish between exact and approximate matches. The greatest bound for the distribution of base set over the documents gives the best matched documents for a search query. The exact and approximate matches are differentiated by considering the normalized term frequency of a term in the specified concept cluster along with its actual presence. The resultant matrix gives a lower dimensional and discriminated representation of dat
