Introduction

In the bustling world of collaborative platforms, the need for intelligent, real-time assistance is more critical than ever. Join me on an exciting journey as we harness the power of MindsDB to craft an intelligent Slack bot capable of providing instant and accurate responses. In this blog post, we'll explore the intricacies of building a knowledge-driven chatbot, unveiling the steps and technologies behind this innovative project.

The Problem:

Communication within Slack channels can be both dynamic and overwhelming. Users often find themselves sifting through threads, seeking relevant information, and waiting for responses. Our goal is to revolutionize this experience by creating a Slack bot that not only understands the nuances of user queries but also delivers real-time, intelligent responses.

Solution

I thought to make a bot that can somehow answer questions are asked in history or similar questions. But how can I do it? do I need to learn ai, vector stores, fetching slack data in Realtime, etc.? this could be time-consuming and very hard. But around same time MindsDB introduced vector DataSource, chatbot, skills and agent. That makes my journey to build this bot really easy.

What is MindsDB?

MindsDB leverages SQL, an effective declarative language for data manipulation, providing an ideal foundation for constructing data-centric AI applications.

Below are most used features of MindsDB:

AI Tables: MindsDB introduces AI Tables, treating AI components (MODELS, AGENTS, KNOWLEDGE BASES) as virtual tables that seamlessly integrate with any datasource using any AI-Engine, enabling advanced SELECT, JOIN, and FINE-TUNE operations.
JOBS Automation: MindsDB empowers automation through JOBS, allowing scheduled queries and trigger-based tasks to enhance efficiency and responsiveness in handling real-time data.
Datasources Connectivity: MindsDB serves as a versatile connector for diverse data sources, excelling in translating SQL queries into requests that access and amalgamate data from databases, applications, vector stores, and more.

How will our bot work?

Building the Knowledge Base:

The foundation of the real-time assistance bot lies in the creation of a robust 'KNOWLEDGE_BASE.' MindsDB's ChromaDB vector datasource became the repository for storing and organizing Slack messages, capturing the essence of conversations in vector form.

The 'KNOWLEDGE_BASE' Skill:

With the 'KNOWLEDGE_BASE' skill, an agent was equipped with the intelligence to understand and respond to user queries. MindsDB's AI-driven SQL capabilities allowed the agent to sift through the data and identify patterns, making it adept at providing instant and accurate responses.

Daily Updates with the 'JOB' Feature:

Ensuring that the 'KNOWLEDGE_BASE' stayed relevant and up-to-date was made seamless with MindsDB's 'JOB' feature. Scheduled updates became a routine, ensuring that the bot evolved alongside the dynamic nature of the Slack channel.

How I Built It:

Steps:

Slack Data Collection: Leveraged MindsDB's Slack datasource to pull real-time data from the Slack channel.

 --Create Datasource
 CREATE DATABASE mindsdb_slack
 WITH
   ENGINE = 'slack',
   PARAMETERS = {
       "token": "xoxb-***********************************"
       "app_token": "xapp-***********************'

     };

 --Query Slack DataSource
 SELECT 
     ts, text, threads
 FROM 
     mindsdb_slack.channels
 WHERE
     channel='general' AND with_threads=true;

ChromaDB Vector Datasource: Stored and organized the data in ChromaDB vector datasource, capturing the semantic meaning of messages.

 CREATE DATABASE slack_vector
 WITH ENGINE = "chromadb",
 PARAMETERS = {
     "persist_directory": "slack_vector"
 };

Embedding Model: Created an embedding model to covert text data to vector representation.

 -- Creating ML_ENGINE for openai

 CREATE ML_ENGINE o_engine FROM openai;

 -- Create Model From ML_ENGINE just created 
 CREATE MODEL open_emb
 PREDICT embeddings
 USING
   engine = 'o_engine',
   mode = 'embedding',
   question_column = 'text', 
   api_key = 'sk-**********************';

Add Slack Data to Vector Datasource: We need to add chats pulled from slack datasource to ChromaDB vectorstore (slack_vector). I used open_emb model to convert text to embedding and add to slack_vector.

 CREATE TABLE slack_vector.general  (
     SELECT c.ts as id , 
     c.text as content , 
     o.embeddings as embeddings , 
     c.threads as metadata
     FROM open_emb o
     join mindsdb_slack.channels c 
     where c.channel='general' and c.with_threads=true

 );

'KNOWLEDGE_BASE' Skill: Developed an agent with a 'KNOWLEDGE_BASE' skill, equipped with MindsDB's AI capabilities to understand and respond to queries.
```
 CREATE KNOWLEDGE_BASE slack_kb
 USING
     model = open_emb,
     storage = slack_vector.general;
```

Create LLM Model: Created a model that will be used to answer our question.

 --CREATE ENGINE
 CREATE ML_ENGINE langchain FROM langchain;
 -- CREATE COVERSATIONAL MODEL
 CREATE MODEL chat_model
 PREDICT answer
 USING
     engine = 'langchain',
     input_column = 'question',
     api_key = 'sk-*********', 
     model_name='gpt-3.5-turbo', 
     mode = 'conversational',
     user_column = 'question' ,
     assistant_column = 'answer',
     max_tokens=100,
     temperature=0,
     verbose=True,
     prompt_template='You have to answer question asked in helpful way.Use tools to get more nice answer';

Agents having Skills: Created a SKILL out of this KNOWLEDGE_BASE, which further needs to assign to AGENT, this AGENTS can have one or more than one SKILLS which CHATBOT can use to get final answer.

 -- Created Skill
 CREATE SKILL slack_skill
 USING
     type = 'knowledge_base',
     source = 'slack_kb', 
     description = 'Use this whenever question is asked about error, MindsDB or technical quwstion';

 --  CREATED Agent from skill AND LLM Mode'
 CREATE AGENT slack_agent
 USING
    model = 'chat_model',
    skills = ['slack_skill'];

Chatbot Integration: Integrated the agent into a Slack bot, transforming insights from MindsDB into real-time assistance for users.

 CREATE CHATBOT vector
 USING
     database = 'mindsdb_slack', 
     agent = 'slack_agent',
     included_channels = ['general'], 
     excluded_channels = [], 
     enable_dms = true,
     is_running = true;

Daily Updates with 'JOB': Implemented MindsDB's 'JOB' feature to schedule daily updates, ensuring the 'KNOWLEDGE_BASE' stayed relevant.

 -- Insert Slack Chat data into Knowledge Base every Day, if there is new data
 CREATE JOB keep_knowledge_base_up_to_date AS (
     INSERT INTO slack_kb (
         SELECT 
             c.ts AS id,
             c.text AS content,
             o.embeddings AS embeddings,
             CONCAT('{"answers":"', REPLACE(c.threads, '"', "'"), '"}') AS metadata
         FROM 
             open_emb o
         JOIN 
             mindsdb_slack.channels c ON o.text = c.text -- Replace with the actual join condition
         WHERE 
             c.channel = 'general' AND 
             c.with_threads = true AND
             AND id > LAST
      );
  ) every DAY;

Challenges I faced while Implementation:

Lack of Threads Table in Slack Datasource:
- Challenge: The absence of a dedicated threads (replies) table in the Slack datasource posed a hurdle to capturing comprehensive conversation data.
- Solution: Leveraging the open-source nature of the Slack datasource, I delved into the code, made modifications, and successfully added both a threads table and a threads column. This enhancement proved instrumental in capturing and analyzing threaded conversations within the Slack channel. (PR Submitted)

Insufficient Data for Testing:

Challenge: Adequate testing requires a substantial amount of real-world data, which was initially lacking.
Solution: To overcome this challenge, I took matters into my own hands. Creating a dedicated Slack channel, I curated and added synthetic chat data, simulating the dynamics of a genuine Slack community. This ensured a more robust testing environment for the chatbot.

Initial Lack of API Key:

Challenge: Access to the OpenAI API key was initially a roadblock in querying the AI model.
Solution: Grateful for MindsDB's support, an OpenAI API key was provided, enabling me to seamlessly integrate and test my project with the MindsDB AI model. This collaboration facilitated the refinement of the real-time assistance bot.

Future Work:

The journey is just started; future plans include expanding the bot's reach by integrating with other platforms like Discord.
Upvote functionality will be introduced, allowing users to indicate the relevancy of responses for improved curation.
Documentation knowledge will be enriched to provide users with comprehensive and detailed insights.
Integration with Stack Overflow is on the horizon to enhance the knowledge base and deliver even more refined and accurate answers.
And much more, as the road ahead promises continuous innovation and evolution.
