Telegram Bot for Monitoring Summarizing and Sending Periodic Qverviews of Channel Posts

 

pexel

To develop a Telegram bot for monitoring, summarizing, and sending periodic overviews of channel posts, follow these steps:

Step 1: Set Up Your Environment

1. Install Python: Ensure you have Python installed on your system.

2. Install Required Libraries:

    ```python

    pip install python-telegram-bot requests beautifulsoup4

    ```

Step 2: Create the Telegram Bot

1. Create a Bot on Telegram: Talk to [@BotFather](https://telegram.me/BotFather) to create a new bot. Note the API token provided.

Step 3: Develop the Bot

1. Monitor Telegram Channels:

    ```python

    from telegram import Bot, Update

    from telegram.ext import Updater, CommandHandler, MessageHandler, Filters, CallbackContext

    import requests

    from bs4 import BeautifulSoup

    TOKEN = 'YOUR_TELEGRAM_BOT_TOKEN'

    CHANNELS = ['@example_channel_1', '@example_channel_2']

    SUMMARY_PERIOD = 60 * 60  # in seconds (1 hour)

    bot = Bot(token=TOKEN)

    def summarize_text(text):

        # Use a simple summarization logic or integrate with an NLP model

        return text[:100] + '...'

    def monitor_channels(context: CallbackContext):

        summaries = []

        for channel in CHANNELS:

            url = f'https://t.me/s/{channel.strip("@")}'

            response = requests.get(url)

            soup = BeautifulSoup(response.text, 'html.parser')

            posts = soup.find_all('div', class_='tgme_widget_message_text')

            for post in posts:

                summaries.append(summarize_text(post.get_text()))

        summary = '\n\n'.join(summaries)

        bot.send_message(chat_id=context.job.context, text=summary)

    def start(update: Update, context: CallbackContext):

        context.job_queue.run_repeating(monitor_channels, SUMMARY_PERIOD, context=update.message.chat_id)

        update.message.reply_text('Bot started! You will receive periodic summaries.')

    updater = Updater(token=TOKEN, use_context=True)

    dp = updater.dispatcher

    dp.add_handler(CommandHandler('start', start))

    updater.start_polling()

    updater.idle()

    ```

2. Customize Channels and Summary Period:

    ```python

    def add_channel(update: Update, context: CallbackContext):

        new_channel = context.args[0]

        if new_channel not in CHANNELS:

            CHANNELS.append(new_channel)

            update.message.reply_text(f'Channel {new_channel} added.')

        else:

            update.message.reply_text(f'Channel {new_channel} already in the list.')

    def remove_channel(update: Update, context: CallbackContext):

        channel = context.args[0]

        if channel in CHANNELS:

            CHANNELS.remove(channel)

            update.message.reply_text(f'Channel {channel} removed.')

        else:

            update.message.reply_text(f'Channel {channel} not found.')

    def set_period(update: Update, context: CallbackContext):

        global SUMMARY_PERIOD

        try:

            new_period = int(context.args[0]) * 60

            SUMMARY_PERIOD = new_period

            update.message.reply_text(f'Summary period set to {new_period // 60} minutes.')

        except ValueError:

            update.message.reply_text('Invalid period. Please provide a number.')

    dp.add_handler(CommandHandler('add_channel', add_channel))

    dp.add_handler(CommandHandler('remove_channel', remove_channel))

    dp.add_handler(CommandHandler('set_period', set_period))

    ```

3. Documentation:

    Provide clear instructions on how to use the bot, including commands to add/remove channels and set the summary period.

Step 4: Ensure Security and Compliance

- Secure Your Bot: Implement security measures to ensure the bot only responds to authorized users.

- Adhere to Telegram's API Usage Policies: Follow Telegram's guidelines and avoid actions that may lead to the bot being banned.

Step 5: Deployment and Support

- Deploy: Host your bot on a server to keep it running continuously.

- Ongoing Support: Be prepared to troubleshoot issues and update the bot as needed.

By following these steps, you can create a robust Telegram bot for monitoring, summarizing, and sending periodic overviews of channel posts.
