Data Mining From Document-Append Nosql

Abstract

Due to the unstructured nature of modern digital data, NoSQL storages have been adopted by some enterprises as the preferred storage facility. NoSQL storages can store schema-oriented, semi-structured, schema-less data. A type of NoSQL storage is the document-append storage (e.g., CouchDB and Mongo) which has received high adoption due to its flexibility to store JSON-based data and files as attachment. However, the ability to perform data mining tasks from such storages remains a challenge and the required tools are generally lacking. Even though there is growing interest in textual data mining, there is huge gap in the engineering solutions that can be applied to document-append storage sources. In this work, we propose a data mining tool for term association detection. The flexibility of our proposed tool is the ability to perform data mining tasks from the document-source directly via HTTP without any copying or formatting of the existing JSON data. We adapt the Kalman filter algorithm to accomplish macro tasks such as topic extraction, term organization, term classification and term clustering. The work is evaluated in comparison with existing textual mining tools such as Apache Mahout and R with promissory result on term extraction accuracy.
