    Study Notes

    Virtual Assistants

    • Virtual Assistants are AI-powered and capable of learning user preferences and habits over time.
    • They can understand natural language, recognize faces, identify objects, and communicate with other smart devices and software.
    • Virtual Assistants are commonly found in mobile devices, such as iPhones with Siri.
    • They can be used to control devices and handle tasks like sending emails and creating to-do lists.
    • Virtual Assistants are often controlled by giving verbal commands.
    • Popular examples include IBM Watson, Google Assistant, Cortana, Alexa, and Siri.

    Chatbots and Virtual Assistants

    • Virtual Assistants are more advanced than chatbots in their ability to interact.
    • Virtual Assistants can understand the semantics of commands, perceive moods and emotions, and hold longer, more coherent conversations.
    • Virtual Assistants can handle complicated tasks, such as finding navigation routes and making restaurant reservations.

    Chatbot Design Process

    • The first step in designing a chatbot is understanding its scope, requirements, and limitations.
    • The second step is identifying user input, such as text, voice, or image queries.
    • The third step involves understanding different user interface elements, such as command line, graphical user interface, menu-driven interface, form-based interface, and natural language interface.
    • The next step is crafting the first interaction and building a conversation flow.
    • The final step is testing the chatbot on mobile devices and websites.

    Chatbot Architecture

    • Intent: Represents the user's intention.
      • Example: The intent of "Good Bye" is to end the conversation.
      • The intent of "What are some good Chinese restaurants" is to find a restaurant.
    • Entity: Modifies an intent.
      • There are three types: system entity, developer entity, and session entity.
    • Candidate Response Generator: Processes user requests using algorithms and generates candidate responses.
    • Response Selector: Selects the most appropriate response based on user queries.

    Best Practices of Chatbot Development

    • Identify the target audience and understand their needs.
    • Set realistic goals for chatbot implementation.
    • Determine which business areas will benefit most from the chatbot.
    • Select the right user platform for the chatbot.
    • Improve the usability and reachability of the chatbot.

    Natural Language Processing (NLP)

    • NLP allows computers to understand text and spoken words like humans.
    • It enables chatbots to convert user text and speech into structured data that machines can understand.

    NLP Steps

    • Tokenization: Splits sentences into smaller parts (tokens) based on meaning.
    • Normalization: Checks word types and converts them to a standard form.
    • Entity Recognition: Identifies keywords to determine the conversation's topic.
    • Semantic Analysis: Infers the meaning of a sentence by understanding the meaning of words and their relationships.

    NLP Cloud

    • NLP Cloud API enables developers to interact with NLP models, including pre-made models for named entity recognition, classification, summarization, question answering, sentiment analysis, and part of speech tagging.
    • Pre-made models include spaCY.io models in 15 languages, Facebook's Bart Large MNLI/CNN models, and Deepset's Roberta Base Squad 2 model.
    • NLP Cloud helps lower the barriers for developers creating apps for tasks like sorting support tickets, extracting leads, analyzing social networks, and developing economic intelligence tools.

    Natural Language Interface (NLI)

    • Provides an abstract layer between humans and computers, allowing them to understand human language instead of the other way around.
    • Allows users to enter natural language search queries in written or spoken text.

    Natural Language Understanding (NLU)

    • A subfield of NLP that focuses on understanding the meaning of human speech by recognizing patterns in unstructured speech input.
    • Has three components:
      • Dictionary: Determines the meaning of words.
      • Parser: Checks if the syntax of the text conforms to language rules.
      • Grammar Rules: Breakdown input based on sentence structure and punctuation.

    Natural Language Generation (NLG)

    • Transforms machine-produced structured data into human-readable text.
    • Steps in NLG:
      • Content Determination: Filtering data to choose what to include in the response.
      • Data Interpretation: Understanding patterns and answers in the knowledge base.
      • Document Planning: Structuring the answer in a narrative manner.
      • Sentence Aggregation: Compiling expressions and words for each sentence.
      • Grammaticalization: Applying grammar rules, punctuations, and spell check.
      • Language Implementation: Inputting data into language templates for natural representation.

    Why Do Chatbots Need NLP?

    • NLP allows chatbots to understand user messages and respond appropriately.
    • It provides context and meaning to text-based user inputs, enabling AI to generate the best response.
