1 Latent Semantic Analyser (Unsupervised Learning)

1.1 An easy way for reducing dimensionality of the data

1.1.1 Importing Libraries

In [1]: import nltk

import numpy as np

from nltk.stem import WordNetLemmatizer

from sklearn.linear_model import LogisticRegression

from bs4 import BeautifulSoup

import matplotlib.pyplot as plt

from sklearn.decomposition import TruncatedSVD

import pandas as pd

1.1.2 Reading data files and adding more stopwords

In [2]: wordnet_lemmatiser = WordNetLemmatizer()

titles = [line.rstrip() for line in open("all_book_titles.txt")]

stop_words = set(w.rstrip() for w in open("stopwords.txt"))

stop_words = stop_words.union({

'introduction', 'edition', 'series', 'application',

'approach', 'card', 'access', 'package', 'plus', 'etext',

'brief', 'vol', 'fundamental', 'guide', 'essential', 'printed',

'third', 'second', 'fourth','and', 'the'})

1.1.3 A custom tokeniser to process every title and extract morphene form of the words out of

it

In [3]: def my_tokeniser(s):

s = s.lower()

tokens = nltk.tokenize.word_tokenize(s)

tokens = [t for t in tokens if len(t)>2]

tokens = [wordnet_lemmatiser.lemmatize(t) for t in tokens]

tokens = [t for t in tokens if t not in stop_words]

tokens = [t for t in tokens if not any(c.isdigit() for c in t)]

return tokens

1

# sample_string = "This is a test sentence to check how the custom tokeniser is working.

# my_tokens = my_tokeniser(sample_string)

# my_tokens

1.1.4 Preparing a word index mapper which maps every word to index in the sentence in

which it occurs

For every review, we break it into a set of tokens and then for each token we check whether itexists in a word to index mapper or not. If it exists we skip it else we store the word in the mapperwith index as the current index of the word index mapper. Word index mapper is required so thatwe can pass tokens to it and it returns the location of the word in the dataframe where we canassign a vector value to it

In [4]: word_index_map = {}

current_index = 0

all_tokens = []

all_titles = []

index_word_map = []

error_count = 0

for title in titles:

try:

title = title.encode('ascii', 'ignore').decode('utf-8') # this will throw exception

all_titles.append(title)

tokens = my_tokeniser(title)

all_tokens.append(tokens)

for token in tokens:

if token not in word_index_map:

word_index_map[token] = current_index

current_index += 1

index_word_map.append(token)

except Exception as e:

print(e)

print(title)

error_count += 1

In [5]: word_index_map["reader"]

Out[5]: 3

In [6]: # Function to convert tokens of a given review and return a "1" at the corresponding location

def tokens_to_vector(tokens):

x=np.zeros(len(word_index_map))

for t in tokens:

i = word_index_map[t]

x[i]=1

return x

In [7]: # Preparing a NXD Matrix

2

N = len(all_tokens) # N=Total number of reviews processed

D = len(word_index_map) # D=Total number of unique tokens extracted out of the reviews

X = np.zeros((D,N)) # Generating a matrix

i=0

In [8]: for tokens in all_tokens:

X[:,i] = tokens_to_vector(tokens)

i+=1

In [9]: all_tokens
