D-HOTM: distributed higher order text mining
We present D-HOTM, a framework for Distributed Higher Order Text Mining based on named entities extracted from textual data that are stored in distributed relational databases. Unlike existing algorithms, D-HOTM requires neither full knowledge of the global schema nor that the distribution of data be horizontal or vertical. D-HOTM discovers rules based on higher-order associations between distributed database records containing the extracted entities. A theoretical framework for reasoning about record linkage is provided to support the discovery of higher-order associations. In order to handle errors in record linkage, the traditional evaluation metrics employed in ARM are extended. The implementation of D-HOTM is based on the TMI [29] and tested on a cluster at the National Center for Supercomputing Applications (NCSA). Results on a dataset simulating an important DEA methamphetamine case demonstrate the relevance of D-HOTM in law enforcement and homeland defense. Keywords Association...
