使用 NLTK 将命令链接到聊天

Question

我正在构建一个简单的聊天机器人，并希望它在给出特定问题/答案时运行命令。

例如： 聊天机器人："我今天能为你做什么？ 用户："打开谷歌" 聊天机器人："开 www.google.com" 聊天机器人运行命令 = WebDriver.open('www.google.com'(

当前用于测试的代码：(TKinter 仅用于测试请忽略 tkinter 代码(

import nltk
from nltk.chat.util import Chat, reflections
import selenium
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import tkinter
from tkinter import *
root = TK()
root.geometry(100x100+100+100)
root.title("Chatbot")
pairs = [
["Hi im (.*)",["hello %1, What can I do for you?"]],
["Open google",["opening www.google.com"]],+OpenG() ##### this is where I need help as concatenating commands does not work
]
def firstChatBot():
print("Greetings! My name is Chatbot-T1, What is yours?.")
Chatbot = Chat(pairs, reflections)
Chatbot.converse()
def openG():
print("Opening www.google.com")
driver = webdriver.Chrome()
driver.get("https://www.googe.com")
btn1 = Button(root, text="Chat", command=firstChatBot).grid(column=1, row=1)
root.mainloop()

Answer 1

nltk 中有类聊天的源代码，它没有运行函数的方法。

您必须使用此代码并更改方法response(和__init__(才能获得三个elemens(pattern, response, function_name)而不是(pattern, response)并运行function_name()。

然后你可以使用

["Open google", ["opening www.google.com"], open_google]

应该有没有()的open_google，其他问题应该None作为第三个要素。

编辑：我添加了matchcallback()所以现在在(.*)中函数问题和所有匹配项，它可以检查有问题的内容。

我使用了Open (.*)所以回调可以检查(.*)中的内容并运行不同的页面。 如果你写Open google那么它会打开www.gooogle.com，如果你写Open so那么它会打开www.StackOverflow.com

import nltk
from nltk.chat.util import Chat, reflections
import re
import random
import webbrowser
class MyChat(Chat):
def __init__(self, pairs, reflections={}):
# add `z` because now items in pairs have three elements
self._pairs = [(re.compile(x, re.IGNORECASE), y, z) for (x, y, z) in pairs]
self._reflections = reflections
self._regex = self._compile_reflections()
def respond(self, str):
# add `callback` because now items in pairs have three elements
for (pattern, response, callback) in self._pairs:
match = pattern.match(str)
if match:
resp = random.choice(response)
resp = self._wildcards(resp, match)
if resp[-2:] == '?.':
resp = resp[:-2] + '.'
if resp[-2:] == '??':
resp = resp[:-2] + '?'
# run `callback` if exists  
if callback: # eventually: if callable(callback):
callback(match)
return resp
# --- create function before `pairs` ---
#def open_google(match):
#    webbrowser.open('https://google.com')
def open_something(match):
#webbrowser.open('https://google.com')
groups = match.groups()
if groups:
if groups[0] == 'google':
webbrowser.open('https://google.com')
elif groups[0] == 'so':
webbrowser.open('https://stackoverflow.com')
else:
print('What is "{}"?'.format(groups[0]))
else:
print("I don't know what to open")
# --- every question needs `callback` or `None`---
pairs = [
["Hi im (.*)", ["hello %1, What can I do for you?"], None],
#    ["Open google", ["opening www.google.com"], open_google],
["Open (.*)", ["opening something ..."], open_something],

print("Greetings! My name is Chatbot-T1, What is yours?.")
Chatbot = MyChat(pairs, reflections)
Chatbot.converse()
