I have a classification problem. How can I group sentences into clusters based on the presence of specific keywords?

One way to group sentences into clusters based on the presence of specific keywords is to use a technique called "keyword-based clustering". Here are the general steps to perform this task:

  1. Define the keywords that you want to use for clustering. These keywords should represent the themes or topics that you want to identify in the sentences.
  2. Preprocess the sentences to remove any irrelevant information or noise, such as stop words, punctuation, or special characters.
  3. Represent each sentence as a vector of features, where each feature corresponds to a keyword and the value indicates whether the keyword appears in the sentence or not. This can be done using various techniques, such as bag-of-words, TF-IDF, or word embeddings.
  4. Cluster the sentences based on their feature vectors using a suitable clustering algorithm, such as K-means, hierarchical clustering, or DBSCAN.
  5. Evaluate the quality of the clusters using metrics such as silhouette score, coherence score, or purity.
  6. Interpret the results by examining the keywords that are most strongly associated with each cluster, and assign a label or topic to each cluster based on these keywords.

Overall, keyword-based clustering can be a simple and effective approach for grouping sentences into clusters based on the presence of specific keywords. However, it may not capture more nuanced semantic relationships between the sentences, and the quality of the clusters will depend heavily on the choice of keywords and the clustering algorithm used.
