1. Research Background and Purpose
The use of Internet of Things (IoT) in the field of energy is emerging as an important agenda, and in particular the smart grid and the oil and gas sectors have been emphasizing research on the utilization of IoT.
The smart grid, which is a product realized by combining information technology, communications technology, and digital-control technology on the power sector, will become the center stage of Energy Internet, a part of IoT. The oil and gas sector, which integrates remote monitoring, sensing, and data analysis, inevitably will emphasize the use of IoT. The utilization of IoT is winning serious consideration in the areas of building energy management and lighting control in addition to the petroleum sector.
IoT provides many benefits such as operational efficiency improvement, asset utilization optimization, new income creation, employee productivity improvement, and industrial safety improvement, and these benefits are also an important value in the energy sector. However, in order for the energy sector to enjoy the benefits of using IoT and minimize the adverse effects, several challenges related to IoT should be addressed. The challenges emphasized in other reports on IoT overall are security, privacy, interoperability, infrastructure cost, sensor energy, big data analysis, stakeholder cooperation, regulation, and consumer acceptability. The benefits and the challenges of IoT will inevitably be highlighted in the energy sector as well.
As IoT is expected to have a variety of influences on the energy sector in the future, this study studies how to exploit IoT in the energy industry and the issues that are expected to emerge in the future by using the future signal searching technique through text mining. The analysis in this study is performed with the following differences from previous studies: First, while most precedent research for the convergence of IoT and energy was focused on the search for IoT applicable areas in the energy industry and the market outlook by consulting institutes, this study proactively examines the common ground between energy and IoT from the perspective of the future signal. Second, this research presents the challenges to overcome the limitations of the future signal searching technique through text mining so that the search will be more accurate. This study thus will provide insight into policies for enhancing the energy industry’s competitiveness by intellectualizing the energy sector.

2. Summary and Policy Implications
Before performing text mining, it is necessary to first build the text mining target database. Since the objective of this study is to capture the issues and the future sign related to IoT, knowledge information that includes the contents of IoT was secured. Thus, the information source containing this knowledge information was to be preferentially selected.
For data collection, the information sources related to IoT and energy were selected through a Google News search. In order to specify the collection target data, Internet of Things or IoT was set as essential key words as the search words in the title, and at least one of the following words is included: energy, smart grid, oil, gas, renewable, nuclear, and coal.
The news search period is from 2010 to April 2015. A total of 1,119 documents have been collected, and duplicates were excluded in the process of collection.
With regard to term frequency, the technological side keywords such as ‘IoT’, ‘technology’, and ‘data’ were at the center, and recently ‘service’ has entered the top three keywords instead of ‘data.’ This indicates that we passed the period of focusing on technology development and have entered the period to pay attention to the application of technology and added value creation. The keywords ‘solutions’ and ‘products’ kept rising in rank in the same context as rise in rank of ‘service.’ Meanwhile, ‘security’ was emerging as one of the major challenges, and the ranking of ‘cloud’, which is associated with big-data analysis, has risen.
In the future signal analysis, ‘solution’, ‘platform’, and ‘software’ were classified as strong signals with regard to IoT components, emphasizing the software side. The keywords ‘analytics’ and ‘storage’ were taken as weak signals, providing the expectation that big data storage and analysis will draw attention in the energy sector as well. In the aspect of stakeholders, ‘customer’ was extracted as a strong signal, indicating that not only the application of IoT and added value creation, but also the importance of customer as the acceptant of IoT technology is naturally being paid attention to and discussed. And ‘utilities’, ‘telecom’, and ‘vendor’ were selected as weak signals, and were emerging as the core of discussion.
In keywords other than the IoT elements and stakeholders, the IoT application area, challenges, and major functions are being discussed. In the application area, ‘building’ and ‘grid’ used to receive high interest; recently ‘gas’ and ‘safety’ have drawn more attention; in the future, ‘wind energy’ and ‘machinery’ will be more paid attention. This takes into consideration that the IoT application scope continues to expand in the energy industry. In terms of challenge, several keywords were selected in relation to the ‘security’ issue. In applying IoT, the response to security threats is recognized as an essential task. Furthermore, from the keywords ‘aggregation’, ‘virtualization’, ‘scalability’, and ‘harvesting’, technology advancement is expected to be discussed more vigorously. As for the principal function aspect, ‘monitoring’ and ‘automation’ used to be the center of topics; the discussion is now being focused on ‘control’ and ‘measurement’; in the future, ‘visualization’, ‘detection’, and ‘maintenance’ will emerge in the discourse.
This study examined the change of interest in IoT in the energy sector by adopting the future signal searching technique through text mining. By analyzing various signals, the authors identified how the issues of concern related to IoT in the energy industry have been changing. Even though the meanings of all the keywords were not explained one by one due to practical limitations, they were categorized into not-strong-but-well-known signals, strong signals, and weak signals to provide the enterprises and the government authorities with insight into the direction of the present and future changes. Furthermore, by presenting several points to be improved in the research methodology, scientific development in future signal study using text mining will be promoted.
