The company also said it would save ¥140m in running costs.
It is said that IBM Watson will carry the knowledge-base of 1000 cancer specialists, which will bring a revolution in the field of healthcare. IBM is regarded as a disruptive innovation. However, the stream of oncology is still in its nascent stage.
Several startups in the healthcare space have been effectively using seven business model archetypes to take solutions based on IBM Watson to the marketplace. These archetypes depends on the value generated for the target user (e.g. patient focus vs. healthcare provider and payer focus) and value capturing mechanisms (e.g. providing information or connecting stakeholders).

..a cautionary tale of hubris and hype" and provides a "representative sample of projects" with their status.

From a review of multiple different papers within the timeframe of 2008–2017,
it was observed within them which of the two techniques were better. The conclusion that was drawn was that “the early classification of these diseases can be achieved by developing machine learning models such as Artificial Neural Network and Bayesian Network.” In another conclusion, Alic, et al. (2017)
was able to draw was that between the two; ANN and BN is that ANN was better and could more accurately classify diabetes/CVD with a mean accuracy in “both cases (87.29 for diabetes and 89.38 for CVD).
Telehealth
The increase of
Telemedicine, has shown the rise of possible AI applications. The ability to monitor patients using AI may allow for the communication of information to physicians if possible disease activity may have occurred. A wearable device may allow for constant monitoring of a patient and also allow for the ability to notice changes that may be less distinguishable by humans.
Electronic health records
Electronic health records are crucial to the digitalization and information spread of the healthcare industry. However logging all of this data comes with its own problems like cognitive overload and burnout for users. EHR developers are now automating much of the process and even starting to use natural language processing (NLP) tools to improve this process. One study conducted by the Centerstone research institute found that

Diaz, “Extraction of Drug-Drug Interaction from Literature through Detecting Linguistic-based Negation and Clause Dependency,” ''Journal of Artificial Intelligence and Data Mining'', vol. 4, no. 2, pp. 203–212, 2016.][R. Cai ''et al.'', “Identification of adverse drug-drug interactions through causal association rule discovery from spontaneous adverse event reports,” ''Artificial Intelligence In Medicine'', vol. 76, pp. 7–15, 2017.][F. Christopoulou, T. T. Tran, S. K. Sahu, M. Miwa, and S. Ananiadou, “Adverse drug events and medication relation extraction in electronic health records with ensemble deep learning methods.,” ''J Am Med Inform Assoc'', Aug. 2019.][D. Zhou, L. Miao, and Y. He, “Position-aware deep multi-task learning for drug–drug interaction extraction,” ''Artificial Intelligence In Medicine'', vol. 87, pp. 1–8, 2018.] Drug-drug interactions pose a threat to those taking multiple medications simultaneously, and the danger increases with the number of medications being taken. To address the difficulty of tracking all known or suspected drug-drug interactions, machine learning algorithms have been created to extract information on interacting drugs and their possible effects from
medical literature
Medical literature is the scientific literature of medicine: articles in journals and texts in books devoted to the field of medicine. Many references to the medical literature include the health care literature generally, including that of denti ...
. Efforts were consolidated in 2013 in the DDIExtraction Challenge, in which a team of researchers at
Carlos III University assembled a corpus of literature on drug-drug interactions to form a standardized test for such algorithms. Competitors were tested on their ability to accurately determine, from the text, which drugs were shown to interact and what the characteristics of their interactions were. Researchers continue to use this corpus to standardize the measure of the effectiveness of their algorithms.
Other algorithms identify drug-drug interactions from patterns in user-generated content, especially electronic health records and/or adverse event reports.

VigiBase allow doctors to submit reports of possible negative reactions to medications. Deep learning algorithms have been developed to parse these reports and detect patterns that imply drug-drug interactions.
