What methods are used for requirements management?

What do people use Formal Concept Analysis for?

Dear @Joseph, I have not used Formal Concept Analysis, but I have read a some papers about this issue, where some application are given. Hope it will be helpful!

Ljubomir:

Thanks for the information.

I will follow up on these.

Take care,

Joe

If annotated properly, you could use FCA to identify dependencies among requirements. If you have text-based requirements, you might start by extracting terms (non-stopwords) from the text and then create a requirement-term incidence relation and look for dependencies there. With other kinds of requirements, you'd have to define your attributes differently.

There is more to it, but the concept lattice in this case is a structure that shows how the terms co-occur in the requirements. These term sets would give the ontology structure.  If the lattice is small enough you can simply draw it and look for interesting relationships, but for larger data sets data mining can be done over sub-lattices of interest. (FCA is under-the-hood of some association rule mining heuristics).

If you need help, I'm just over the bridge.

Benjamin:

Thanks for the reply, information and offer.

This is an area that I am just starting to explore in more depth.

Any specific software packages that would be suitable for text-based requirements?

As you point out, some pre-processing would need to be done.

Take care, be good to yourself and have fun,

Joe

Joe,

The Uta Priss link below is the goto page for FCA resources. I haven't looked to see if there are any readily available FCA tools that deal directly with text.

My guess is that you'll have to adapt some pre-existing text mining tool to your purpose, and getting the right terms can require a little cleverness.  You might try annotating with all n-grams for say n up to 4. The concepts will contain redundant n-grams (in the sense that every 4-gram has four 3-grams as subphrases, etc), so you'll want to simplify each concept leaving only the k-grams that don't occur in another n-gram in the concept. A little messy, but would avoid the need to be too clever.

PS Not sure they will help, but I do have some tutorial slides on SlideShare (www.slideshare.net/BenjaminKeller). I do update them as I find mistakes.

PSPS I don't have electronic copies of the papers you requested -- ResearchGate doesn't allow me to tell you that directly

Ben:

Thanks for the information...

My plan is to start working this in the next few weeks...

Have a great holiday...

Joe

Ljubomir:

Thanks again for the pointer to the papers.

These have provided a great start.

Take care,

Joe

You are very welcome dear @Joseph! Wish You a very good research. Happy New Year to all of our RG friends!

Benjamin:

Just scanned your slides on slideshare and the code on GitHub..

Very interesting... I will digest the material more as I move forward.

Have a great new year..

Joe

Joe, I just noticed yesterday that the Ganter "Formal Concept Analysis: Foundations and Applications" book has a section on Software Engineering. Though, it probably duplicates Ljubomir's list somewhat.

Dear @Benjamin, better duplicate resource than none, right! @Joseph, I hope the research is ongoing good! Good luck!

Benjamin:

Thanks for the information.  

I have the book, 'Formal Concept Analysis: Mathematical Foundations."

It seems like I need to read the book you mentioned.

Thanks again, be good to yourself and have fun,

Joe

Ljubomir:

You are correct...

We sill see where things go over the next few months...

Have fun,

Joe

We have two papers on use of concept lattices in this area:
