llorllale · 2018-02-23T20:18:30Z

@yegor256 this metric also requires Latent Semantic Indexing. Have you thought high-level about how we should integrate this into the project? I'm referring to Java vs. XSLT.

llorllale · 2018-02-26T13:38:37Z

@yegor256 I'd like your input on my previous comment in order to know the direction I should be taking with this job

@llorllale I don't really know what this metric is about. Let's start to investigate and see where it gets us. I have zero knowledge in this area, don't rely on me.

llorllale · 2018-03-01T21:44:05Z

@yegor256
A lot of math is involved. On one hand there are already Java libraries out there that we could reuse. On the other, we could implement through XSLT by hand.

Following are the steps for this metric. Singular-value decomposition will definitely be the hardest:

Latent Semantic Analysis: https://en.wikipedia.org/wiki/Latent_semantic_analysis
1. Build the occurrence matrix
2. Rank lowering (to mitigate problems of synonymy and polymeny):
  1. Singular-value decomposition:
    - Wikipedia: https://en.wikipedia.org/wiki/Singular-value_decomposition
    - HOW-TO: https://fenix.tecnico.ulisboa.pt/downloadFile/3779576344458/singular-value-decomposition-fast-track-tutorial.pdf
    - HOW-TO: http://www.cs.utexas.edu/users/inderjit/public_papers/HLA_SVD.pdf
    - How to solve quadratic equations: http://pages.cs.wisc.edu/~amos/412/lecture-notes/lecture02.pdf
  2. Select k ranks. This should be configurable/user-provided
3. Calculate cosine similarity between the resulting documents pairs: https://en.wikipedia.org/wiki/Vector_space_model
Calculate ACSM as per paper
Calculate C3 as per paper

Also, there will be a limitation:

The paper says The source code under analysis is converted into a text corpus, such that from each method only identifiers and comments are extracted. Comments are not included in the bytecode, they are not mentioned in the class file format specification

Finally, I'll be very curious to see the performance of this.

@paulodamaso This task seems very complex and not doable with a budget of 30min, because is opened since Oct 2017, and was refused by about 21 DEVs. I think it should be subtasked. Do you suggest that I proceed with it with PDD, or just refuse it, and submit a ticket about it's complexity to be re-formulated?

paulodamaso · 2019-08-27T12:26:39Z

@fellahi-ali The issue has already been decomposed in some way by @llorllale in #16 (comment) ; I think you could start by solving one of these steps and lefting puzzles for the other ones, WDYT?

alilosoft · 2019-08-27T13:03:59Z

@paulodamaso OK! I think I should give it a try. But as I'm not familiar with PDD, I don't know exactly the constraints/rules of using puzzles, and when I should leave them and when I couldn't? I will start by reading the articles about PDD, and if you can give any hints it will be appreciated!

Hi, is this a good first issue? I'd like to contribute and I'm familiar with the metric.

paulodamaso · 2019-10-05T23:55:47Z

@luiscruz Currently this issue is waiting for #296 solution. Can you solve it with the current architecture?

luiscruz · 2019-10-06T00:10:10Z

I'm not familiar with the architecture yet.
Perhaps I should start with a simpler issue and then get back to this.
Any recommendation @paulodamaso ?

paulodamaso · 2019-10-06T00:43:08Z

@luiscruz I think that as you are familiar with the metrics, this should be a good issue to you to get familiar with the current architecture. Or you could get into #296 and provide a solution for it.

We use @0crat to manage the project issues, so it would be a good idea for you to join it if you want to contribute actively
