PROBLEM STATEMENT OF PROPOSED PROJECT
• The need arises for an efficient and accurate sentiment analysis tool specifically tailored for
Facebook comments. This tool should seamlessly integrate with Facebook's data structure,
providing real-time or near-real-time analysis to capture dynamic sentiment changes. Existing
sentiment analysis tools may lack the capability to fully understand the intensity and polarity of
sentiments expressed in user comments, limiting their effectiveness in providing nuanced insights.
Moreover, challenges such as handling slang, adapting to evolving language trends, and ensuring
scalability further contribute to the limitations of current systems.
• The proposed project aims to address these challenges by developing a robust sentiment analysis
system using the VADER sentiment analysis tool. The system will not only automate sentiment
classification but also provide comprehensive user Interface for view account and Post statistics
related to the user. Integration with Facebook's data structure will enable the analysis of large
volumes of comments, allowing users to gain valuable insights into the sentiment distribution,
comment intensity trends, and overall sentiment patterns associated with specific accounts or posts.

EXISTING SYSTEM AND THEIR LIMITATIONS
• 1. Accuracy and Contextual Understanding:
• Many existing sentiment analysis systems may struggle with accurately understanding the context of user-
generated content, leading to misinterpretations of sentiment.
• 2. Scalability Challenges:
• Traditional sentiment analysis methods may face challenges in scaling to handle the vast amount of data
generated on social media platforms like Facebook, resulting in slower processing times.
•
3. Inability to Capture Intensity:
• Some sentiment analysis tools might provide binary sentiment labels (positive/negative) but may lack the
capability to capture the intensity or strength of the sentiment expressed in a comment.
• 4. Limited Adaptability to Slang and Emojis:
• Existing systems may not be well-equipped to handle the use of slang, colloquial expressions, or emojis
commonly found in social media language, potentially leading to misinterpretation
• 5. Dependency on Predefined Lexicons:
• Systems relying on predefined sentiment lexicons may struggle with staying updated and may not effectively
adapt to evolving language trends and the emergence of new words.

IMPLEMENTATION DETAILS
Pseudo-code implementation of the first half:
NLTK:is used for understanding of human natural language.
Matplotlib: is a python module used for data visualization and and 2D plotting for
representation of data.
NumPy: is a python package used for scientific and computional methods in python.
Pandas: is a python module used for data preprocessing and analysis .
->pip install numpy,matplotlib,pandas,nltk

2) Youtube-API setup
import googleapiclient.discovery
import googleapiclient.errors
api_service_name = "youtube"
api_version = "v3"
DEVELOPER_KEY = "AIzaSyBWZoWKKtgc5s-oHTE5P_l0FwafRENBkow"
VIDEO_ID = "-1gF6PIB1YQ" # <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< Enterthe video id here
youtube = googleapiclient.discovery.build(
api_service_name, api_version, developerKey=DEVELOPER_KEY)
request =youtube.commentThreads().list(
part="snippet",
videoId=VIDEO_ID,
maxResults=100
)
response = request.execute()
text = ''
for item in response['items']:
# print(item['snippet']['topLevelComment']['snippet']['textDisplay'])
text += item['snippet']['topLevelComment']['snippet']['textDisplay']

21
3) After we open a file we preprocess the text through tokenize, stemize and then lemmatize:
Tokenize the text, i.e split words from text.
sent_tokenizer = PunktSentenceTokenizer(text)
sents = sent_tokenizer.tokenize(text)
print(word_tokenize(text))
print(sent_tokenize(text))
4)Stemize and lemmatize the text for normalization of the text:
a)For stemize we use PorterStemmer() function:
from nltk.stem.porter import PorterStemmer
porter_stemmer =PorterStemmer()
nltk_tokens = nltk.word_tokenize(text)
for w in nltk_tokens:
print (“Actual: %s Stem: %s” % (w, porter_stemmer.stem(w)))
b) For lemmatize we use WordNetLemmatizer() function :
from nltk.stem.wordnet import WordNetLemmatizer
wordnet_lemmatizer = WordNetLemmatizer()
nltk_tokens = nltk.word_tokenize(text)
for w in nltk_tokens:
print (“Actual: %s Lemma:%s” % (w, wordnet_lemmatizer.lemmatize(w)
Actual: This Stem: thi
Actual: is Stem: is
Actual: very Stem: veri
Actual: Bad Stem: bad
Actual: and Stem: and
Actual: good Stem: good
Actual: . Stem: .
Actual: This Lemma: This
Actual: is Lemma: is
Actual: very Lemma: very
Actual: Bad Lemma: Bad
Actual: and Lemma: and
Actual: good Lemma: good
Actual: . Lemma: .
['This', 'is', 'very', 'Bad', 'and', 'good', '.']
['This is very Bad and good.’]

22
5) POS( part of speech) tagging of the tokens and select only significant features/tokens like
adjectives, adverbs, and verbs, etc.
text = nltk.word_tokenize(text)
print(nltk.pos_tag(text))
6)Pass the tokens to a sentiment intensity analyzer which classifies the Facebook comments as
positive, negative or neutral.
sid = SentimentIntensityAnalyzer()
tokenizer = nltk.data.load(‘tokenizers/punkt/english.pickle’)
with open(‘kindle.txt’,encoding=’ISO-8859-2′) as f:
for text in f.read().split(‘n’):
print(text)
scores = sid.polarity_scores(text)
for key in sorted(scores):
print(‘{0}: {1}, ‘.format(key, scores[key]), end=”)
print()
This is very Bad and good.
compound: -0.1604, neg: 0.346, neu: 0.365, pos: 0.289,
[('This', 'DT'), ('is', 'VBZ'), ('very', 'RB'), ('Bad', 'NNP'), ('and', 'CC'), ('good', 'JJ'), ('.', '.')]

RESULTS & CONCLUSION

Limitations of Project work implemented :-
1.Static Video ID:
The script uses a static VIDEO_ID variable to fetch comments for a specific video. This limits the script's flexibility, as it would need
to be modified manually each time you want to analyze comments for a different video.
Hardcoded API Key:
2.The YouTube Data API key (DEVELOPER_KEY) is hardcoded in the script. This could pose a security risk if the code is shared or
made publicly accessible, as the API key grants access to the associated YouTube account's data. Best practices involve securing
API keys and not hardcoding them directly in the code.
3.Rate Limiting and Quotas:
The YouTube Data API has usage quotas and rate limits. If the script makes too many requests in a short period, it may hit these
limits and result in temporary restrictions. Proper rate-limiting strategies and error handling for quota issues are essential for a
robust implementation.
Data Processing:
4.The script collects comment text but does not perform any meaningful analysis on the sentiment or other aspects of the
comments. Depending on the project's goals, additional processing steps may be necessary to derive insights from the collected
data.
5.project involves retrieving comments from a Facebook page, the access token handling in the script may need further
consideration. Facebook Graph API access tokens have expiration periods, and refreshing them programmatically may be required.
Code Modularity:
6.The script lacks modularity, making it less reusable for different scenarios. Encapsulating functionalities into functions or classes
could enhance code organization and maintainability..
