GSoC Idea: Build an expert system to provide recommendations to users in a user interface

[vchrombie]

The new version of SortingHat provides a basic recommender system. It tells information about what identities could be the same, or what identities work for which companies. This information might not be useful for the end-user and it isn't available on the UI, though.

SortingHat is the tool that we use to manage identities data in GrimoireLab. As individuals in a project can have different identities - several usernames or email addresses - this tool allows creating unified profiles of them. Then, the platform will use this information to generate accurate results of the activity of these participants.

SortingHat started as a command-line tool but after some years, we saw its potential and we decided to create a new version, this time as a service. This new version provides a new GraphQL API to operate with the server and a UI web-based app, that replaces Hatstall, the old UI for SortingHat.

Although the development of it is in its later stage and it will be ready soon for the stable version of the platform, there are many good ideas that we will like to incorporate. Some of them were selected for GSoC 2021.

The aims of the project are as follows:

• Identify useful recommendations for the end-user.
• Implement new recommendations.
• Integrate recommendations on the UI.

The aims will require generating code in Python for Django and the GraphQL API, and for the web app (generated with Vue.js and Vuetify).

• Difficulty: Hard
• Requirements: Interest in software analytics. Python programming. JavaScript programming. SQL knowledge. Willingness to understand GrimoireLab internals.
• Recommended: Experience with Python, JavaScript, UI development, GraphQL, Django, and Vue.js would be convenient but can be learned during the project.
• Mentors: @sduenas @evamillan @mafesan

Microtasks

For becoming familiar with GrimoireLab, you can start by reading some documentation. You can find useful information at:

• GrimoireLab Tutorial
• SortingHat: Wizardry on Software Project Members
• The GitHub repositories hosting the tools (chaoss/grimoirelab-perceval, chaoss/grimoirelab-elk, chaoss/grimoirelab-*...).

Once you're familiar with Grimoirelab, you can have a look at the following microtasks.

• Microtask 0:
  Download PyCharm and get familiar with it (for instance, you can follow this tutorial).

• Microtask 1:
  Set up a dev environment to work on GrimoireLab. Have a look at chaoss/grimoirelab-sirmordred - Getting-Started.md.

• Microtask 2:
  Execute micro-mordred to collect, enrich and visualize data from Git repositories.

• Microtask 3:
  Based on the elasticsearch documents produced by micro-mordred and source code of chaoss/grimoirelab-elk, try to answer the following questions:

  • What is the meaning of the JSON attribute author_id?
  • What is the meaning of the JSON attribute author_org_name?
  • What is the meaning of the JSON attribute author_uuid?
  • What is the meaning of the JSON attribute author_domain?
  • What is the meaning of the JSON attribute uuid?
  • What is the meaning of the JSON attribute utc_commit?
  • What is the meaning of the JSON attribute origin?

• Microtask 4:
  Set up the developer environment of SortingHat (muggle branch).

  NOTE: The sortinghat muggle branch is a WIP branch. As of now, it doesn't work with the core of the GrimoireLab platform but we hope to have it ready soon.

• Microtask 5:
  Create a sample profile with different identities and enrollments using the SortingHat UI.

• Microtask 6:
  Using the SortingHat GraphQL Console, create a query that fetches the data (identities, enrollments) of an individual profile.

• Microtask 7:
  Create a script that can parse the gitdm developer affiliation files and load the data in a SortingHat database using GraphQL.

• Microtask 8:
  Improve the visualization of the individualCards component. You need not send a PR, please update the work in your personal fork.

• Microtask 9:
  Submit a PR to any of the GrimoireLab components to increase the test coverage of one or more files of the source code.

• Microtask 10:
  Submit at least a PR to one of the GrimoireLab repositories to fix an issue, improve the documentation, etc. Some good-first-issues are:

  • https://github.com/chaoss/grimoirelab-perceval/issues/692
  • https://github.com/chaoss/grimoirelab-perceval/issues/691
  • https://github.com/chaoss/grimoirelab-elk/issues/951

[stevenkolawole]

Hello!

I'm Steven Kolawole, a Computer Science Junior from FUNAAB, Nigeria. GrimoireLab has piqued my interest right since when I joined the CHAOSS community back in February. Following the GrimoireLab's tutorial, I'm fairly familiar with how it works.

I have a strong background in Machine Learning and I've done two prior internships in Data Science and Machine Learning Engineering roles. My ML background means that I'm familiar with recommender systems, having built one myself (albeit on a small scale and it didn't go into production). I'm also a decent Django developer as I've also interned in a Backend Engineering role before. I'm familiar with JS basics and I'm happy to strengthen my knowledge of it, likewise all the other necessary requirements that I don't know for now.

It's really exciting to be here. I plan to learn a lot and hopefully, have lots of fun while at this. Thank you for having me. 😄

[Venkatavaradan-R]

Hi There!

My name is Venkat and I'm a CSE Junior studying in Bangalore, India. I've been interested in GrimoireLab ever since I joined the community back in November 2020.

I've got a good amount of experience with building and integrating/hosting ML models (especially NLP and recommender systems) having done 2 internships, one as a Data Science Intern and one as a Backend Developer (Funnily having to implement a recommender system for a recipe app :laughing: ). I have also worked with JavaScript-based frameworks like React JS. I was just wondering whether this is on a first-come-first-serve basis?

I'm super glad to see this project and hoping to contribute as much as I can in the near future! :smiley:

[darmis007]

Hello!

I am Darsh Mishra a sophomore studying at BITS Pilani. I am an experienced Django Developer having written bug-free code for websites serving payments, carrying out registrations, and managing a functioning of a large-scale college fest. I also have experience of developing ML Models especially recommendation systems which I learned during an internship and have been effectively been used in an online trade fair. I have also worked with JS frameworks like ReactJS so catching up with Vue JS would not be a problem for me. I would love to contribute to this project

[galexad]

Hi! I am Gabriela Alexandru, a 1st year Computer Science student at Vrije Universiteit(VU) Amsterdam. I have some experience with Python and ML, having done an internship in Natural Language Processing where I worked on a conversational AI system. I have also some Javascript(node.js & jquery) skills from recently completing a course in Web technology as a part of my degree.

I'm comfortable with using Linux/bash terminal and commands, as well as github, and I could describe myself as a fast learner, ambitious and self-motivated student.

I would like to participate in this project in order to learn more about how to build a recommender system, especially due to my interest in NLP, but also because I find this a challenging project that would bring me a great learning experience. As a newbie, I am very excited to get to know more about how to contribute to open source and become part of a community whom I could help and who could help me grow.

Find me on linkedin :)

[vchrombie]

Hi everyone, thanks for your interest in applying for this idea. You can start working on the microtasks to get a better idea of the project. Let us know if you have any doubts. :slightly_smiling_face:

I was just wondering whether this is on a first-come-first-serve basis?

@Venkatavaradan-R, this is not on a first-come-first-serve basis. You have to submit a proposal as per the GSoC Guidelines and also attempt at least one microtask.

[vchrombie]

For all students interested in this idea, please comment on this issue to get in touch with the mentors. This is the main communication channel.

[rohanreddych]

Hello @vchrombie I'm trying to understand the problem statement.

The new version of SortingHat includes a basic recommender system. It guesses about what identities could be the same, or what identities work for which companies. This information might not be useful for the end user and it isn't available on the UI, thought. This project idea is about improving the recommender system to an expert system that provides useful recommendations to users

The goal of the project is to show "recommendations of profiles which might be same" to the user through the UI. We have to create the recommendation system using machine learning / AI.

Am i correct?

No. No machine learning/AI. It's very complicated for a project of one month. It's more important to use the methods that we already know, to improve them and to find a way to visualize that data with the current UI.

[rohanreddych]

Hello, @sduenas I was trying the new sortinghat server and ui can you give some data to test the graphql console. and sortinghat_db.auth_user

[vchrombie]

Hi @rohanreddych, I understand you are asking about the microtask-6. Let me know if I'm are wrong.

Hello, @sduenas I was trying the new sortinghat server and ui can you give some data to test the graphql console.

You can use the data that was stored in the database after the microtask-5.

and sortinghat_db.auth_user

You can create a admin user using createsuperuser which can be used to login. https://djangocentral.com/creating-super-user-in-django/

We will try to add some minimal documentation soon.

[rohanreddych]

You can create a admin user using createsuperuser which can be used to login.

Thanks, @vchrombie. I was able to enter data through UI and retrieve it through the graphql console.

The aims of the project are as follows:

• Identify useful recommendations for the end-user.
• Implement new recommendations.
• Integrate recommendations on the UI.

@sduenas , @evamillan, @mafesan Can you please explain a little more about the project? I was looking at the recommendations/engine.py currently, affiliations and profile matching are implemented, and there are plans to implement gender recommendations (#471). What other recommendations are to be implemented?

[WasimAkhtarKhan]

Hello, I am Wasim Akhtar Khan studying Information Technology from BIT Durg , a GSOC aspirant and a passionate learner. I have been using Django since last year and would like to contribute in this project. I have seen the Microtasks and looking forward to work with you for a long time. Thank You @vchrombie

[vchrombie]

Hi, @SteveKola @Venkatavaradan-R @darmis007 @galexad @rohanreddych @WasimAkhtarKhan I hope you started working on the microtasks. As you might know, you have to submit a proposal before the GSoC deadline. You are also expected to attempt at least one microtask for considering your application.

The main reason behind the microtasks is, these tasks will give a good minimum understanding of the Sorting Hat tool as well as the GrimoireLab platform as a whole. It will be really helpful for writing your proposal.

If you haven't started working on the microtasks yet, I would suggest you start asap. You can create a github repository for storing the microtasks and you can open issues in that repo for asking doubts or reviewing the tasks.

Thanks.

Hello @vchrombie , I have gone through tutorials of GrimoireLab platform and SortingHat, setup the dev environment, and have started working on microtasks. It is very much interesting. Thank You

[WasimAkhtarKhan]

Hello @vchrombie @sduenas , This is just to make sure that I am doing right: Step 1: Setup dev environment using Only Docker as given in chaoss/grimoirelab-sirmordred - Getting-Started.md. Step 2: Then Running grimoirelab/full Step 3:Then for executing micro-mordered I used this Tutorial In this Tutorial, It is given that I will get this Couldn't find any Elasticsearch data. You'll need to index some data into Elasticsearch before you can create an index pattern But I got the required dashboard without running this command $ python3 micro.py --raw --enrich --cfg setup.cfg --backends git The image I got is:

Is there anything I am doing wrong then please correct me.

[rohanreddych]

@WasimAkhtarKhan

You'll need to index some data into Elasticsearch before you can create an index pattern But I got the required dashboard without running this command $ python3 micro.py --raw --enrich --cfg setup.cfg --backends git The image I got is:

That's because you are running the grimoirelab container.

Use docker-compose to run the docker-compose.yml file in https://chaoss.github.io/grimoirelab-tutorial/sirmordred/micro-mordred.html. You will get the expected result.

Correct me if I am mistaken. :smile:

[vchrombie]

Hi @WasimAkhtarKhan

Step 1: Setup dev environment using Only Docker as given in chaoss/grimoirelab-sirmordred - Getting-Started.md.

You have to use the source code and docker method for setting up the dev environment.

• Why not docker? You don't get to work with source code if you are using only docker method.

The image I got is:

The image looks good to me. It is the expected output.

[WasimAkhtarKhan]

Hi @WasimAkhtarKhan

Ok I will set up with source code and docker method

Ok Nice. Thanks @vchrombie

[WasimAkhtarKhan]

Hello @vchrombie , @rohanreddych I set up the PyCharm and python interpreter. I am getting two problems

• First one:

After executing python3 micro.py --raw --enrich --cfg ./setup.cfg --backends git cocom in terminal. I am getting this error and

• Second is:

When I try to resolve Package requirement "grimoirelab-elk" is not satisfied by terminal and by Install Requirement I get this

[rohanreddych]

First one:

Port 9200, so there is a problem with elasticsearch,I don't think you have elasticsearch running. Is there an elasticsearch instance running on your system?

To solve this, I recommend using docker-compose as I said in the previous comment.

Second one:

I got similar errors related to requirements. Can you create a new virtualenv and do pip install requirements.txt ? If that does not solve your errors then vchrombie can help you.

[vchrombie]

Hi @WasimAkhtarKhan

* First one:

After executing python3 micro.py --raw --enrich --cfg ./setup.cfg --backends git cocom in terminal. I am getting this error

Looks like the elasticsearch is not running at the required port. Can you confirm if there are no errors in the logs of docker-compose? You should have elasticsearch, kibiter, and MariaDB/MySQL running in the respective ports. docker-compose with searchguard

* Second is:

When I try to resolve Package requirement "grimoirelab-elk" is not satisfied by terminal and by Install Requirement

You have to set the Project Structure too, along with Project Interpreter. The Project Structure should have all the grimoirelab repositories. Setting up PyCharm

I got similar errors related to requirements. Can you create a new virtualenv and do pip install requirements.txt ? If that does not solve your errors then vchrombie can help you.

@rohanreddych, this works but it would be better you use the source code of elk instead of using the pip package.

The grimoirelab dependencies must be loaded using Project Interpreter, whereas the rest of the dependencies should be installed using Project Interpreter.

For example, I'm providing an excerpt from the SirMordred requirements.txt file.

colorlog==4.1.0
elasticsearch==6.3.1
elasticsearch-dsl==6.3.1
file-read-backwards==2.0.0
-e git+https://github.com/chaoss/grimoirelab-toolkit/#egg=grimoirelab-toolkit
-e git+https://github.com/chaoss/grimoirelab-sortinghat/#egg=grimoirelab-sortinghat
-e git+https://github.com/chaoss/grimoirelab-kidash/#egg=grimoirelab-kidash
...

In this case

• colorlog, elasticsearch, elasticsearch-dsl, file-read-backwards should be installed using Project Interpreter
• grimoirelab-toolkit, grimoirelab-sortinghat, grimoirelab-kidash should be loaded using Project Structure which are present in the sources folder

If you are installing everything using pip install -r requirements.txt the pip packages are installed, the source code won't be used.

[WasimAkhtarKhan]

Hello @vchrombie

Looks like the elasticsearch is not running at the required port. Can you confirm if there are no errors in the logs of docker-compose? You should have elasticsearch, kibiter, and MariaDB/MySQL running in the respective ports. docker-compose with searchguard

When I execute sudo docker-compose up -d. It is saying Starting elasticsearch Output is: And after executing sudo docker-compose logs It is displaying some error message of Unable to revive connections and No living connections

I tried to use docker-compose-without-searchguard.

You have to set the Project Structure too, along with Project Interpreter. The Project Structure should have all the grimoirelab repositories. Setting up PyCharm

Yes I have set the Project Structure along with Project Interpreter of all gremoirelab components as per Setting up PyCharm

[rohanreddych]

@WasimAkhtarKhan Elasticsearch has not started, thats why kibana is showing that warning. Once stop all the containers, run sysctl -w vm.max_map_count=262144 and then start again.

Thank you @rohanreddych Starting elasticsearch This output confused me. You were right. Now I got the Elasticsearch running on port 9200. Thanks @vchrombie

[vchrombie]

Thanks, @rohanreddych for helping.

@WasimAkhtarKhan

I tried to use docker-compose-without-searchguard.

Cool, but I think you might need to change the es endpoints in the setup.cfg file if you are using without searchguard.

[es_collection]
url = http://localhost:9200

[es_enrichment]
url = http://localhost:9200

The setup.cfg has all the configurations related to es, kibiter, sortinghat, etc. So, please make sure the configurations are correctly set.

[WasimAkhtarKhan]

Ok I'll. Thanks @vchrombie

[WasimAkhtarKhan]

Hi @vchrombie While executing Micro-Mordred --raw --enrich --cfg ./setup.cfg this configuration works fine. But after --panels this configuration it is giving an error

[vchrombie]

Hi @WasimAkhtarKhan, can you confirm the full command which you are trying to execute?

The configuration should be something like Script path: path of the micro.py Parameters: --panels --cfg ./setup.cfg --backends git (since you need only panels) Working directory: path to sirmordred utils folder

We can have a quick chat incase if it is not solved.

https://github.com/chaoss/grimoirelab/issues/414#issuecomment-807050075

@WasimAkhtarKhan

#414 (comment)

I see you have mentioned only --panels in the parameters. Please add the full configuration. It should be --panels --cfg ./setup.cfg --backends backend-name.

Ok I tried from here. Should it be changed? Sorry and Thanks @vchrombie

[rohanreddych]

Hello @vchrombie I think we need to improve the error message here. https://github.com/rohanreddych/grimoirelab-sirmordred/blob/b9686e874b49270ceefae1e3286eed4dcffa4248/sirmordred/task_panels.py#L277

Should i start working on this?

[vchrombie]

https://github.com/chaoss/grimoirelab/issues/414#issuecomment-807064135

No problem @WasimAkhtarKhan, please let me know if that solved the issue.

Interesting. @rohanreddych, would you be interested to submit a PR for it?

[WasimAkhtarKhan]

No problem @WasimAkhtarKhan, please let me know if that solved the issue.

Yea It solved it. I tried many things to solve that issue myself. Your reply motivates me Thanks @vchrombie

Hi @rohanreddych, looks like there is some issue with sortinghat. The error comes from here, sortinghat_gelk.py#L74. Do you have MySQL/MariaDB installed on your machine? If yes, then there should be something wrong with the configurations. Can we have a quick chat sometime later today? I'm free after 15:00 IST.

[rohanreddych]

Yes, I have mysql installed. I do sudo service mysql stop then do docker-compose up so that there wont be any errors in ports.

Can we have a quick chat sometime later today? I'm free after 15:00 IST.

How? IRC or matrix?

[vchrombie]

OperationalError: (2002, “Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)”)

Hi @WasimAkhtarKhan, it looks like a db connection issue. You have to update the config/settings/devel.py file with the password of the MySQL service. devel.py#L102.

[vchrombie]

How? IRC or matrix?

We can connect at #grimoirelab at Freenode. I will be there at 15:00 IST.

Hi @rohanreddych, the logs look fine to me.

You can check if the indexes are created using curl. (I assume you are using the searchguard version, if not please change the es URL).

$ curl -XGET -k "https://admin:admin@localhost:9200/_alias?pretty"

You can execute the micro-mordred with the --panels flag to activate the panels task so that the dashboards are created and you can check them in kibiter http://localhost:5601.

micro.py --raw --enrich --panels --cfg ./setup.cfg --backends git

[rohanreddych]

@sduenas , @evamillan, @mafesan Can you please explain a little more about the project? I was looking at the recommendations/engine.py currently, affiliations and profile matching are implemented, and there are plans to implement gender recommendations (#471). What other recommendations are to be implemented

[sduenas]

The main purpose of the idea is to have useful recommendations for the system.

The first problem we want to address is which recommendations we really need. Right now, we have those you mentioned but maybe they need to be reformulated. For example, the current recommendations for affiliations answer the question of "at what organization do these people work?" but maybe it's more useful to answer "who works for this organization?".

In the case of the individuals, the recommendations are based on two sets of individuals to try to answer the question "which individuals are the same from these two groups?". Maybe we can create a higher layer which only does that for those individuals that weren't found before, or for those that work for a certain company, or maybe for the new ones that are added to the database. Also, we can expand the way we find these recommendations. For example, now we do some basic matching like if the email address is the same, then the individuals are the same. The problem gets more complicated when a person changed from one job to another so their email addresses are different now.

The second problem is how to visualize all these information in the UI and how the user can accept those recommendations.

All of these should be part of your proposal. You have to keep in mind that the work will last only one month or so, so try to adapt your proposal for that. Don't try to include too many things. Try to be reasonable according to the effort and time restrictions. More doesn't need mean better.

Hi everyone, the student application period has started and the deadline is 13 April 2021, 18:00 UTC. GSoC Timeline

Please continue working on the proposal and complete as many microtasks as possible. Please let us know if you need any help with doubts or reviewing the microtasks. Thanks!

Hello @sduenas,

According to the GSOC page, the program would hold for two months. 10 weeks, to be exact. But you said the project would last for a month. Is there a mixup at somewhere or something?

[vchrombie]

The program has changed a bit. I will post the brief timeline here, to avoid any confusion.
