解説
問 32
Incorrectア
Activity is a general word denoting 'activity' or 'action' itself. Although it is sometimes used for functions such as a smartwatch's exercise-amount measurement, it is not a technical term that collectively refers to the technology or records that continuously record an individual's diverse activities. It does not express the meaning of 'the technology for recording / the records themselves' that the stem asks for, so it is incorrect.
Incorrectイ
Transaction refers to a unit of a series of processes (dealings) in a database or business system, denoting a processing unit that should be executed indivisibly, such as bank deposits/withdrawals or inventory updates. It does not mean the technology for recording an individual's daily activities or such records, so it is incorrect.
- ウ
正解 Lifelog is a term that refers to the technology for continuously recording the various activities people perform in daily life (movement, purchases, searches, posting, etc.) through digital devices, sensors, and web services, or to such records themselves. The examples listed in the stem—'movement history on public transportation (transit IC cards, etc.),' 'product search history on websites,' and 'data posted on SNS or blogs'—all leave the traces of an individual's behavior and activities as data, which are exactly typical examples of a lifelog. Therefore the correct answer is ウ.
Incorrectエ
Record keeping is a general English expression meaning 'the retention and management of records,' referring to clerical work in general such as storing ledgers and documents. It is not an established term denoting the technology for digitally recording activities such as movement, searches, and posting, nor is it the most appropriate term for the content the stem illustrates, so it is incorrect.
ここがポイント
- Lifelog is a term referring to the technology for continuously recording an individual's daily activities and experiences (movement, purchases, searches, SNS posting, etc.) as digital data, as well as to such records themselves.
- Being able to distinguish it from similar options (Activity / Transaction / Record keeping) based on the definition of 'continuously turning an individual's activities into data and recording them.'
