New task: noun compound interpretation about nlp-progress

[tianjianjiang]

If I may suggest a rough idea: how about using “multiword expression” as an umbrella category for the time being?

[sebastianruder]

How about adding this to shallow syntax? Would that work?

[girishponkiya]

No. This task is at the semantic level, and it is "mostly" out-of-context. I would suggest making a new category, named Noun Compound Interpretation.

[sebastianruder]

Good point. I'm a bit hesitant to create a separate category for it as it's quite a specialized task. How about we add it to relationship extraction for now but make it clear that this setting does not depend on the context?

[girishponkiya]

I agree that it looks tiny and a specialized task. But, the representation of relation makes it totally different. For instance, a semantic relation in a noun compound can be represented by means of..

• prepositional paraphrasing: e.g., student protest => "protest by student", fee-hike protest => "protest against fee-hike" (Ponekiya et al., 2018)
• fine-grained paraphrases using verbs: e.g., malaria mosquito can be paraphrased using carry, spread, cause, transmit, etc. (Nakov, 2008)

From this relation representation perspective, the task is totally different from Relationship Extraction.

Additionally, there are many different types of relation inventories and datasets, and proposed system for those datasets. Adding this task to Relationship Extraction will complicate the things.

@tianjianjiang, that's a good idea. We can have two different sections for conventional multiwords (mostly non-compositional) and noun compounds (mostly compositional).

Thanks for adding your opinion, @tianjianjiang. I agree with the proposal. Feel free to create a Multiword expression category and add this task there. 👍
