Description

Take a sentence, convert it into a vector. Take many other sentences, and convert them into vectors. Find sentences that have the smallest distance (Euclidean) or smallest angle (cosine similarity) between them. Convert words and sentences into high-dimensional vectors, each vector's geometric position can attribute meaning. Measure of semantic similarity between sentences.

Description

Identification of financial documents based on text given in it. OCR for scanned documents. Extraction of text from PDF document using pypdf and ocrmypdf libraries. Pre-processing on extracted text using re and nltk libraries. Conversion of textual data in vector format using TFIDF and Word2Vec. Classification of textual data with ML algorithms like SVM, Decision Tree, Random Forest, and XGBoost. Used deep learning techniques like BERT, DIstilBERT, and encoder-decoder for better accuracy with sequential data. Post classification integration of the model using flask.

Description

For tabular data extraction used tabula library. Also used object detection techniques to identify tables dynamically. Used labelme to annotate the tabular data. Used Faster RCNN, YOLOV3, and YOLOV5 for tabular data detection. Post detection of tabular data used clustering techniques to generate table in CSV format. Extraction and preparation of tabular data which are extracted from PDF. To extract tabular data used object detection methods like FasterRCNN, YOLOV3, and YOLOV5. Prepare summary from a large document and used Extractive and Abstractive methods. Used gensim and sumy libraries to generate the summary of text. Used methods like LSA and LexRank to generate summary of documents. For Topic modeling worked on LDA also, with this I have identified the topics from a large corpus.
