A Review on Document Clustering Using Concept Weight
نویسنده
چکیده
Traditional document clustering techniques are mostly based on the number of occurrences and the existence of keywords. The term frequency based clustering techniques takes the documents as bag-of words while ignoring the relationship between the words. Similarly Phrase based clustering technique only captures the order in which the words appear in a sentence instead of determining the semantics behind the words. Considering the drawbacks of such system this paper proposes a concept based clustering technique. The ideology behind this concept is uses Medical Subject Headings MeSH ontology for extracting the concept and the concept weight calculation is done by its identity and relationship with its synonym. The method used for clustering documents on Semantic is called K-medoid algorithm through which the results are analyzed.

Data mining, also known as knowledge discovery in database, is the process to discover unknown knowledge from a large amount of data. Text mining is to apply data mining techniques to extract knowledge from unstructured text. Text clustering is one of important techniques of text mining, which is the unsupervised classification of similar documents into different groups. The most important step...

Text clustering and classification are two main tasks of text mining. Feature selection plays the key role in the quality of the clustering and classification results. Although word-based features such as term frequency-inverse document frequency (TF-IDF) vectors have been widely used in different applications, their shortcoming in capturing semantic concepts of text motivated researches to use...
