Question
Automated medical image analysis
EBBZS IT, based in Groningen, the Netherlands, intends to develop a system using artificial intelligence (AI) to help doctors at Joelstraat Hospital interpret medical images.
Due to the high resolution* of the digital images (see Figure 4), EBBZS IT claims the AI system will be able to learn from these images to assist doctors when diagnosing patients’ illnesses.
EBBZS IT also claims the AI system will be able to cope with the significant increase in the volume of patients and the increased complexity of their symptoms and conditions.

* resolution: the detail an image holds. It can be measured in pixels per centimetre.
Discuss the claim by EBBZS IT that the diagnosis of patients’ illnesses should be based on the information provided by the AI system.
Markscheme
Answers may include:
Reasons for basing the diagnosis of the patients on the recommendations of the AI system (claim):
- It is more likely to give consistent information (systems).
- It may increase the transparency / acceptability of the process if the algorithms are made available.
- The automation of this process may be used to improve the throughflow of patients, as diagnoses could be linked to non-serious cases only (systems, costs).
- It may provide a second opinion that a medical professional can use as the basis for making a decision (systems).
- The automation of this process may act as a method of allocating less urgent patients to nurses and leaving the more serious conditions to doctors (costs, feasibility).
Reasons for not basing the diagnosis of the patients on the recommendations of the AI system (counter-claim):
- The accuracy of the diagnosis will depend on the quality/volume/range of data available in the AI system (costs, feasibility).
- The AI system may contain bugs or may not have been tested sufficiently (costs, feasibility).
- The AI system does not take into account the medical history of the patient, so cannot exhibit judgement or use intuition (values, ethics).
- The AI system cannot make decisions based on ethical criteria.
- There might be a new situation that could not be anticipated, which would be difficult for the AI system to analyse (systems, feasibility).
- It raises issues linked to accountability / acceptability if there are problems that emerge as a result of an incorrect diagnosis (power).
In this question it is expected there will be a balance between the terminology related to digital systems and the terminology related to social and ethical impacts.
Keywords: health, AI, artificial intelligence, pattern recognition, image analysis, storage, judgement, intuition, accountability, digital media, image, change, power, systems, values, ethics, feasibility, acceptability, costs

Cameras in school
The principal at Flynn School has received requests from parents saying that they would like to monitor their children’s performance in school more closely. He is considering extending the school’s IT system by installing cameras linked to facial recognition software that can record student behaviour in lessons.
The facial recognition software can determine a student’s attention level and behaviour, such as identifying if they are listening, answering questions, talking with other students, or sleeping. The software uses machine learning to analyse each student’s behaviour and gives them a weekly score that is automatically emailed to their parents.
The principal claims that monitoring students’ behaviour more closely will improve the teaching and learning that takes place.
Discuss whether Flynn School should introduce a facial recognition system that uses machine learning to analyse each student’s behaviour and give them a score that is automatically emailed to their parents.

App or intuition?
Apps have been developed that allow a customer to submit a trip request to a taxi company on their smartphone. These apps allow the customer to select the starting point and final destination of the journey as well as add other information, such as the time of journey and number of passengers.
The developers of the taxi journey app claim it can capture the real-time details of a journey, including the starting point, route, distance travelled, the speed of the car and the final destination. The app integrates this information with real-time traffic information, such as closed roads or accidents. Fares can be estimated before the journey, and the customer can pay digitally with their credit card or by PayPal.
Some traditional taxi drivers in cities such as Paris and Rio de Janeiro have campaigned against the introduction of these apps in taxi companies. Based on previous journeys recorded by the app, the taxi company recommends that their taxi drivers rely on the taxi journey app rather than their own knowledge of the city when determining the best route.
Discuss whether the taxi driver should rely on the taxi journey app, rather than their own knowledge of the city, when determining the best route.

18N.1.HL.TZ0.6:
Selecting candidates for political parties
Political parties often have large numbers of applicants who wish to act as representatives in their various governing bodies. A senior party official must make the final decision about which applicants should be offered which roles. Many roles receive as many as 15 applications, and it is not possible to interview each applicant.
In an attempt to streamline the application process, a prospective representative will need to complete two tasks:
- Completing an online questionnaire.
- Submitting a video where they explain the reasons behind their application.
Neither task will involve the team in the political party.
The applicants will be directed to a link provided by the software developer where they can complete both tasks. The responses to the questionnaires and the videos will be analysed using artificial intelligence (AI).
The software will score the questionnaire and video for each applicant and send it to the senior party official’s team. The applicants with the highest scores will then be invited by the political party for an interview.
The software developers claim this will reduce the number of applications the senior party official needs to process and lead to the most appropriate applicants being selected for an interview.
Discuss whether the political party should introduce the digital system to assist the senior party official when deciding which applicants should be offered roles as representatives.

Clouds under the sea
Microsoft has located one of its data centres on the seabed. Project Natick is now operating 100 feet below the surface of the North Sea (see Figure 4).
Figure 4: An artist’s representation of a data centre on the sea bed
[Adapted under sea photo by NOAA on Unsplash]
Microsoft has chosen to develop data centres on the seabed because they claim there are concerns about the environmental impact of data centres built on land. These seabed data centres can be constructed and placed on the sea bed in 90 days. This is compared to the two years that are required for land-based data centres.
Google patented their design for an underwater data centre in 2009. Even though functioning prototypes have been trialled, none have been used commercially.
The demand for data storage is doubling every two years, so it is likely that an increasing number of data centres will need to be constructed. These data centres can be constructed either under the sea or on land.
Discuss whether companies like Microsoft should build data centres on the seabed.

The human face of student counselling
Many Diploma Programme (DP) coordinators are finding they do not have enough time to interview every student before they choose their DP subjects. They are considering purchasing the Student Counselling System, a proprietary management information system (MIS).
The developers of the Student Counselling System claim that, if students complete online questionnaires to determine their interests, abilities and future goals, the system can give them very accurate results, resulting in less than 5% of students changing their diploma subjects. They also claim the Student Counselling System will allow DP coordinators to be able to interview every student, something they cannot do now.
Some DP coordinators have concerns about the automation of this process and believe that advising students is something that is best done by relying on their own professional judgement and intuition.
Discuss whether DP coordinators should rely on the recommendations of the Student Counselling System rather than their own professional judgement and intuition when advising students about what DP subjects to study.
