This work provides a generic review of the existing data mining ontologies (DMOs) and also provides a base platform for ontology developers and researchers for gauging the ontologies for satisfactory coverage and usage.

The study uses a systematic literature review approach to identify 35 DMOs in the domain between the years 2003 and 2021. Various parameters, like purpose, design methodology, operations used, language representation, etc. are available in the literature to review ontologies. Accompanying the existing parameters, a few parameters, like semantic reasoner used, knowledge representation formalism was added and a list of 20 parameters was prepared. It was then segregated into two groups as generic parameters and core parameters to review DMOs.

It was observed that among the 35 papers under the study, 26 papers were published between the years 2006 and 2016. Larisa Soldatova, Saso Dzeroski and Pance Panov were the most productive authors of these DMO-related publications. The ontological review indicated that most of the DMOs were domain and task ontologies. Majority of ontologies were formal, modular and represented using web ontology language (OWL). The data revealed that Ontology development 101, METHONTOLOGY was the preferred design methodology, and application-based approaches were preferred for evaluation. It was also observed that around eight ontologies were accessible, and among them, three were available in ontology libraries as well. The most reused ontologies were OntoDM, BFO, OBO-RO, OBI, IAO, OntoDT, SWO and DMOP. The most preferred ontology editor was Protégé, whereas the most used semantic reasoner was Pellet. Even ontology metrics for 16 DMOs were also available.

This paper carries out a basic level review of DMOs employing a parametric approach, which makes this study the first of a kind for the review of DMOs.

In 2015, the Supreme Court of India directed the Government of India to confer the citizenship right to the Chakma refugees, who settled in North-Eastern States in India. Arunachal Pradesh, the former North Eastern Frontier Agency, holds a large number of Chakma refugees who had migrated to India from the erstwhile East Pakistan during the late 1960s. The present benevolent approach of the Government of India towards this ethno-refugee community is having domestic as well as external implication in the backdrop of rampant deportation of refugees from its neighbouring state, Bangladesh. Mere citizenship right may result in the administrative integration of the Chakmas but could not resolve their crises as alien versus indigenous debate intensifies the refugee crises today. Over the decades, political alienation of the Chakma refugees extended their sense of deprivation and marginalization. A separate perspective is required to assess the Chakmas’ claim that they are after all not alien to India since their ancestral land Chittagong Hill Tracts were under Indian territory and they have had a deep allegiance to this territory because of India's accommodative pluralistic outlook and multi-ethnic characters. Permanent means of livelihood, legal rights over land holding and bridging social capital would help ethnic integration, not merely ‘limited’ citizenship right. This study from ethno-political perspective would assess the crises of the Chakma refugees in Arunachal Pradesh in India.
