I'm not sure how this construction makes sense. It's like domain name parking. what does building knowledge even mean? complex problems? why not simple ones? Didn't they used to call this "talking"??
Anyway if someone cares to share any knowledge they might have, it would be appreciated.
“Languaging” or “doing language” is a collaborative dialogic activity or a process of making meaning and building knowledge through language to solve complex problems.
Edit: mistook what you meant by "academically desperate" most likely but I am not 100% sure about what you did mean by it. New usages have vague definitions since there is not enough usage yet and it may very well be a new way to say "talking" but the definition you gave makes it sound more like a new way to say "discussing."
You may want to read up on how language evolves and grows.
Edit a tad more:
Did a bit of digging and "languaging" has its first recorded use (according to google books) back in the early 1800s and has had a fairly regular niche usage up until the 1960s where use starts to increase.

Their sibling project, The Oxford Dictionary of English, is going to be much more current on slang. The names are confusing, but aside from having the same publisher they're almost completely unrelated. The OED is an academic project for past language evolution; the Oxford Dictionary of English is a practical dictionary for use by everyday English speakers.
meaning everything and the contrary of it? check
new? No, seemingly it is around since many years, very likely "invented" by Merrill Swain:

cannot say in which of her many papers it was used first.
