User Story #3A: Find Quotes By Decade

by ADMIN 38 views

=====================================================

Overview

As a linguist, analyzing the evolution of language over time is crucial for understanding the nuances of human communication. To facilitate this analysis, we need to be able to retrieve quotes from specific decades. This user story focuses on developing a feature that allows users to find quotes by decade, enabling them to study the language patterns and trends of different time periods.

Problem Statement

Given the vast collection of quotes available, it can be challenging to identify and retrieve quotes from a specific decade. This is particularly true when dealing with large datasets, where manual searching and filtering can be time-consuming and inefficient. To address this issue, we need to develop a system that can efficiently retrieve quotes by decade, allowing linguists and researchers to focus on their analysis rather than data collection.

Requirements

To implement the "Find quotes by decade" feature, we need to meet the following requirements:

  • Given a specific decade, the system should return all quotes from that decade.
  • Given a list of decades, the system should return all quotes from those decades.
  • When requesting quotes by one decade, the system should return the first 1000 quotes from that decade.
  • The system should be able to handle large datasets and retrieve quotes efficiently.

Technical Requirements

To develop the "Find quotes by decade" feature, we will need to implement the following technical requirements:

  • Database schema: We will need to design a database schema that stores quotes with their corresponding decade information.
  • Decade filtering: We will need to implement a decade filtering mechanism that allows users to select specific decades or lists of decades.
  • Quote retrieval: We will need to develop a quote retrieval mechanism that can efficiently retrieve quotes from the database based on the selected decade(s).
  • Pagination: We will need to implement pagination to limit the number of quotes returned to the first 1000.

Design

To design the "Find quotes by decade" feature, we will follow a modular approach, breaking down the implementation into smaller components. This will enable us to develop and test each component independently, ensuring that the final product meets the requirements.

Database Schema

Our database schema will consist of two tables: quotes and decades.

  • quotes table:
    • id (primary key): unique identifier for each quote
    • text: the actual quote text
    • decade: the decade in which the quote was written
  • decades table:
    • id (primary key): unique identifier for each decade
    • start_year: the start year of the decade
    • end_year: the end year of the decade

Decade Filtering

To implement decade filtering, we will create a decade_filter component that takes a list of decades as input and returns a filtered list of quotes.

class DecadeFilter:
    def __init__(self, quotes):
        self.quotes = quotes

    def filter_by_decade(self, decades):
        filtered_quotes = []
        for quote in self.quotes:
            if quote['decade'] in decades:
               _quotes.append(quote)
        return filtered_quotes

Quote Retrieval

To implement quote retrieval, we will create a quote_retrieval component that takes a list of filtered quotes as input and returns the first 1000 quotes.

class QuoteRetrieval:
    def __init__(self, filtered_quotes):
        self.filtered_quotes = filtered_quotes

    def retrieve_quotes(self):
        return self.filtered_quotes[:1000]

Pagination

To implement pagination, we will create a pagination component that takes a list of quotes as input and returns the first 1000 quotes.

class Pagination:
    def __init__(self, quotes):
        self.quotes = quotes

    def paginate(self):
        return self.quotes[:1000]

Implementation

To implement the "Find quotes by decade" feature, we will combine the decade_filter, quote_retrieval, and pagination components.

def find_quotes_by_decade(quotes, decades):
    decade_filter = DecadeFilter(quotes)
    filtered_quotes = decade_filter.filter_by_decade(decades)
    quote_retrieval = QuoteRetrieval(filtered_quotes)
    retrieved_quotes = quote_retrieval.retrieve_quotes()
    pagination = Pagination(retrieved_quotes)
    paginated_quotes = pagination.paginate()
    return paginated_quotes

Testing

To ensure that the "Find quotes by decade" feature works as expected, we will write unit tests for each component.

import unittest

class TestDecadeFilter(unittest.TestCase):
    def test_filter_by_decade(self):
        quotes = [
            {'decade': '1950s'},
            {'decade': '1960s'},
            {'decade': '1970s'}
        ]
        decades = ['1950s', '1960s']
        filtered_quotes = DecadeFilter(quotes).filter_by_decade(decades)
        self.assertEqual(len(filtered_quotes), 2)

class TestQuoteRetrieval(unittest.TestCase):
    def test_retrieve_quotes(self):
        quotes = [
            {'decade': '1950s'},
            {'decade': '1960s'},
            {'decade': '1970s'}
        ]
        filtered_quotes = [
            {'decade': '1950s'},
            {'decade': '1960s'}
        ]
        retrieved_quotes = QuoteRetrieval(filtered_quotes).retrieve_quotes()
        self.assertEqual(len(retrieved_quotes), 2)

class TestPagination(unittest.TestCase):
    def test_paginate(self):
        quotes = [
            {'decade': '1950s'},
            {'decade': '1960s'},
            {'decade': '1970s'}
        ]
        paginated_quotes = Pagination(quotes).paginate()
        self.assertEqual(len(paginated_quotes), 3)

if __name__ == '__main__':
    unittest.main()

Conclusion

In this user story, we developed a feature that allows users to find quotes by decade. We implemented a decade filtering mechanism, quote retrieval, and pagination to efficiently retrieve quotes from the database. We also wrote unit tests to ensure that the feature works as expected. This feature will enable linguists and researchers to analyze the evolution of language over time, providing valuable insights into human communication.

Future Work--------------

In the future, we can improve the "Find quotes by decade" feature by:

  • Adding more filters: We can add more filters, such as author, topic, or language, to allow users to narrow down their search results.
  • Improving pagination: We can improve pagination by allowing users to select the number of quotes to retrieve per page.
  • Enhancing quote retrieval: We can enhance quote retrieval by using more efficient algorithms or data structures to reduce the time it takes to retrieve quotes.

By continuing to improve and expand the "Find quotes by decade" feature, we can provide users with a more powerful and flexible tool for analyzing language patterns and trends over time.
