Can "time-consuming" be used as a noun?
In Google I find more hits for its usage as noun, in phrases such as:
...problems such as time-consuming, low...
I could only find one example of its use as a noun: http://ieeexplore.ieee.org/document/6780067/
In conventional approach to mine data, we often use to join several relations to form a single relation using foreign key links, which is known as flatten. Flatten may cause problems such as time consuming, data redundancy and statistical skew on data."
This is just an error by a non-native writer of English. There are other errors, such as the missing article before "conventional"
In general, there is no reason why "time-consuming" cannot be a noun (or a gerund), but it would be rare and odd. An expression like "Time wasting" may often be better:
In English, we form some adjectives using a noun and a present participle or past participle:
- A time-consuming or time-wasting activity
- An experience-enhancing situation
- A money-spending initiative
- A fun-loving child
- An alcohol-fueled evening
- A cash-driven investment
- A gun-toting bandit
Generally speaking, none of those can be used as nouns. When one has mastery of the formation of this kind of adjective, one is considered to be an advanced speaker of the language.
