# Master MDS
Use NLP techniques you learned so far (N-gram models, basic machine learning, no neural nets) to analyse texts or to build an application. Document
your approach.

    - consist solely of alphabetic characters
    - Lemmatization


# Process 
- Tokenization
- (Normalization)
- Feature Extraction
- Feature analysis
- Prediction

# Features

- N Grams 
    - (paper: Computationally recognizing wordplay in jokes)
- structual patterns 
    - (paper: Centric Features)

    - Questions -> Answer
    - Oneliner
    - Wordplay 
    - Dialog

# TODOS:
- 1. __Feature extraction and correlation__
    - 1a: Structual pattern 
        - maybe 2 people? 
        - look at structual_pattern.ipynb
        - data: structual pattern -> Sentencization
        -  Paper Research on strucutal patterns
    - 1b: extented length analysis 
        - small task 
        - look at token_normal.ipynb
        - distribution normalization
        -  Paper Research on strucutal patterns
        - ggf. Bericht Inhaltsverzeichnis,...
        
    - 1c: N-Grams
        - data: csv files
    - 1d: Embeddings
        - data: csv files
        - word2vec? (paper: Centric Features)

   
- 2. Machine Learning / logistic regression
    - (coming soon...)



# Topic presentations (graded) (5 min)
## Focus:
- What is your overall idea?
- What kind of data will you use and where do you get the data?
- Your approach, which techniques will you use?
- Expected results.

## Open Questions:
- How to evaluate similarity?
- How to find structural patterns? (like phrases, setups, punchlines, or wordplay)


## Possible Hypothesis:
- Similar jokes share more common n-grams, phrases, or structural patterns.
- Basic features like word frequency, sentiment, length, or punctuation can predict joke ratings.

other ideas:
- The length of a joke (measured in words or characters) is inversely correlated with its average rating, as shortness may enhance comedic impact.

- Highly rated jokes follow certain structural patterns (e.g., setups, punchlines, or wordplay).

## Possible Tools / Techniques

- __Text Preprocessing:__ Tokenization, stopword removal, stemming/lemmatization.
- __Feature Extraction:__ Bag-of-Words, n-grams (bigram/trigram analysis), TF-IDF.

- __Similarity:__ Cosine similarity for finding similar jokes.
