Engineering Intelligent NLP Applications Using Deep Learning – Part 2 Saurabh Kaushik
This document discusses how deep learning techniques can be applied to natural language processing tasks. It begins by explaining some of the limitations of traditional rule-based and machine learning approaches to NLP, such as the lack of semantic understanding and difficulty of feature engineering. Deep learning approaches can learn features automatically from large amounts of unlabeled text and better capture semantic and syntactic relationships between words. Recurrent neural networks are well-suited for NLP because they can model sequential data like text, and convolutional neural networks can learn hierarchical patterns in text.
Sentimental analysis is a context based mining of text, which extracts and identify subjective information from a text or sentence provided. Here the main concept is extracting the sentiment of the text using machine learning techniques such as LSTM Long short term memory . This text classification method analyses the incoming text and determines whether the underlined emotion is positive or negative along with probability associated with that positive or negative statements. Probability depicts the strength of a positive or negative statement, if the probability is close to zero, it implies that the sentiment is strongly negative and if probability is close to1, it means that the statement is strongly positive. Here a web application is created to deploy this model using a Python based micro framework called flask. Many other methods, such as RNN and CNN, are inefficient when compared to LSTM. Dirash A R | Dr. S K Manju Bargavi "LSTM Based Sentiment Analysis" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-5 | Issue-4 , June 2021, URL: https://www.ijtsrd.compapers/ijtsrd42345.pdf Paper URL: https://www.ijtsrd.comcomputer-science/data-processing/42345/lstm-based-sentiment-analysis/dirash-a-r
The document discusses word embedding techniques, specifically Word2vec. It introduces the motivation for distributed word representations and describes the Skip-gram and CBOW architectures.

A NOVEL APPROACH FOR NAMED ENTITY RECOGNITION ON HINDI LANGUAGE USING RESIDUA...kevig
Many Natural Language Processing (NLP) applications involve Named Entity Recognition (NER) as an important task, where it leads to improve the overall performance of NLP applications. In this paper the Deep learning techniques are used to perform NER task on Hindi text data as it found that as compared to English NER, Hindi language NER is not sufficiently done. This is a barrier for resource-scarce languages as many resources are not readily available. Many researchers use various techniques such as rule based, machine learning based and hybrid approaches to solve this problem. Deep learning based algorithms are being developed in large scale as an innovative approach now a days for the advanced NER models which will give the best results out of it. In this paper we devise a Novel architecture based on residual network architecture for preferably Bidirectional Long Short Term Memory (BiLSTM) with fasttext word embedding layers. For this purpose we use pre-trained word embedding to represent the words in the corpus where the NER tags of the words are defined as the used annotated corpora. BiLSTM Development of an NER system for Indian languages is a comparatively difficult task. In this paper, we have done the various experiments to compare the results of NER with normal embedding and fasttext embedding layers to analyse the performance of word embedding with different batch sizes to train the deep learning models. Here we present a state-of-the-art results with said approach F1 Score measures.

Suggestion Generation for Specific Erroneous Part in a Sentence using Deep Le...ijtsrd
This document presents a method for generating suggestions for specific erroneous parts of sentences in Indian languages like Malayalam using deep learning. The method uses recurrent neural networks with long short-term memory layers to train a model on input-output examples of sentences and their corrections. The model takes in preprocessed sentence data and generates a set of possible corrections for erroneous parts through multiple network layers. An analysis of the model shows that it can accurately generate suggestions for word length of three, but requires more data and study to handle the complex morphology and symbols of Malayalam. The performance of the method is limited by the hardware used and it could be improved with a more powerful system and additional training data.

2. ABSTRACT
• Learning a new language is difficult for all and its even more difficult for a computer to
learn and process human language. But due to the recent techniques in Deep
Learning(DL) Natural Language Processing(NLP) tasks are enhanced significantly,
but these models cannot be entirely generated using NLP models. In order to meet
the latest trends Natural Language Understanding(NLU) a subfield of NLP is
emerged. NLU tasks include things like machine translation, text entailment, dialogue
based systems, natural language inference, sentiment analysis. The advancement in
the field of NLU can enhance the development in these models.
3. INTRODUCTION
• NLU is the emerging nowadays due to the increase in the GPT models , it mainly
concentrates on analyzing and extracting information from human language text.
NLU tasks include information-retrieval, summarization, language translation,
classification. NLU aims to attain the task proficiency for tasks contained in
standard benchmarking datasets like GLUE (General Language Understanding
Evaluation) and superGLUE. (Super GLUE).
4. METHODOLOGY
• The methodology mainly consists of key-phrases required to search results,
inclusion and exclusion criteria, selection results, quality assessments extraction
and data synthesis. The below table shows the evolution of models in NLU
5.
6. BACKGROUND
• NLU includes building language models training them, testing them for accuracy.
This section contains the text classification tasks used in this paper. there are two
types of QA tasks QA extractive and generative QA, we are only considering
extractive QA in this part. NLI is used to predict whether we can predict meaning
of one text from other. neural machine translation is used as a process to
translate text by simulating human brain capabilities, the main goal of this part is
to retain the meaning and intent of the language while translating if from one to
other
9. FEED FORWARD NETWORK BASED MODELS
• Simple DL models for text representation include feedforward networks. Despite
this, they have a good level of accuracy on several TC benchmarks. Text is
viewed as a collection of words in these models. These models acquire a vector
representation for each word by word2vec. These are popular embeddings
models .Joulin et al. [23] introduced another classifier called fastText. It is efficient
and straightforward
10. RNN-BASED MODELS
• Usually, the text is treated as an order of words in RNNbased models. The basic
purpose of an RNN-based model for text categorization is to capture word
relationships between sentences and text structure. Plain RNN-based models, on
the other hand, do not perform as well as standard feed-forward neural networks.
11. MODELS BASED ON CNN
• CNNs are taught to identify patterns in space, while RNNs are trained to detect
patterns over time [30]. RNNs perform well in NLP tasks like RQA-POS tagging,
which need an understanding of long-range semantics, but CNN performs well in
situations where sensing local and location-independent patterns in the document
is critical.
12. CAPSULE NEURAL NETWORK-BASED MODELS
• CNN uses several layers of convolutions and pooling to classify pictures or text.
Pooling operations detect significant features and minimize the computation
complexity of convolution processes, but they miss spatial information and may
misclassify items depending on their orientation or proportion.
13. MODELS WITH MECHANISM OF ATTENTION
• The way one pays attention to distinct sections of a photograph or related words
of a single sentence motivates attention. Attention is becoming a central concept
and tool in developing DL models for NLP [45]. It can be thought of as a vector of
significant weights in a nutshell.
14. MODELS BASED ON GRAPH NEURAL NETWORKS
• Even though ordinary texts have a serial order, they also comprise inherent graph
structures similar to parse trees that speculate the relationships based on syntax
and semantics of the sentences.
15. MODELS WITH HYBRID TECHNIQUES
• Many hybrid models have been built to detect global and local documents by
combining LSTM and CNN architectures.
16. MODELS BASED ON TRANSFORMERS
• The sequential processing of text is one of the computational obstacles that
RNNs face. Even though RNNs are more sequential than CNNs, the computing
cost of capturing associations among words in a phrase climb with the length of
the sentence, much like CNNs.

18. DISCUSSIONS AND LIMITATION
• Large number of research papers are considered for this aspect in building large
language models in DL
19.
20. • The above mentioned framework is proposed for creating NLU models in future, it
is mainly done considering BERT models. The models has two parts multi-tasking
and pre training, the proposed framework should work well as it combines
multiple techniques.
• Current models employ text classification tasks due scarcity of literature and
research in multi tasking DL models in NLU, and availability of large number of
models makes it difficult to find the suitable model and that meets the
requirements
21. CONCLUSION
• Majority of issues faced by multi taking learning are same and the findings
suggest that a hybrid model that contains strategies from Multi task learning and
active learning , still there is lot of scope to figure out how to improve accuracy
and resilient MTL models for general AI and next gen models
