20 NLP Projects with Source Code for NLP Mastery in 2023

Because the amount of text data is so large, while providing people with more usable information, it also makes it more difficult for people to find the information that interests them most. Therefore, how to dig out important information from massive information has very high research value and practical significance. Due to the different needs of users, how to excavate the characteristics of different users and find exclusive information for them has become the main problem that should be solved in current information processing. The text classification technology using artificial intelligence algorithms can automatically and efficiently perform classification tasks, greatly reducing cost consumption. It plays an important role in many fields such as sentiment analysis, public opinion analysis, domain recognition, and intent recognition.

As AI and NLP become more ubiquitous, there will be a growing need to address ethical considerations around privacy, data security, and bias in AI systems. All areas of the financial industry employ NLP, including banking and the stock market. NLP structures unstructured data to identify abnormalities and possible fraud, keep track of consumer attitudes toward the brand, process financial data, and aid in decision-making, among other things. Ability to perform previously unachievable analytics due to the volume of data.

Changing Cybersecurity with Natural Language Processing

In fact, NLP is a tract of Artificial Intelligence and Linguistics, devoted to make computers understand the statements or words written in human languages. It came into existence to ease the user’s work and to satisfy the wish to communicate with the computer in natural language, and can be classified into two parts i.e. Natural Language Understanding or Linguistics and Natural Language Generation which evolves the task to understand and generate the text.

This is mainly because, in the word frequency-based user interest set method proposed in this chapter, the direct use of the SVM classifier is avoided. Therefore, it effectively reduces the average time overhead of the sample classification generated in the classification process. As can be seen from Figure 4, the input of the TPM Chinese word segmentation model is still a piece of preprocessed Chinese text [13, 14]. First, through the embedding layer of the model, the natural language is converted into a text vector that can be recognized by the computer. Then, the powerful semantic feature extraction ability of the BERT model is used to extract semantic features, which is equivalent to reencoding the text according to the context semantics. Then, according to the original dataset where the input data is located, the semantic feature vector is inputted into the corresponding Bi-GRU model of the private layer.

Challenges of natural language processing

One of the most interesting aspects of NLP is that it adds up to the knowledge of human language. The field of NLP is related with different theories and techniques that deal with the problem of natural language of communicating with the computers. Some of these tasks have direct real-world applications such as Machine translation, Named entity recognition, Optical character recognition etc. Though NLP tasks are obviously very closely interwoven but they are used frequently, for convenience. Some of the tasks such as automatic summarization, co-reference analysis etc. act as subtasks that are used in solving larger tasks. Nowadays NLP is in the talks because of various applications and recent developments although in the late 1940s the term wasn’t even in existence.

• It employs NLP and computer vision to detect valuable information from the document, classify it, and extract it into a standard output format.
• Syntax is the grammatical structure of the text, whereas semantics is the meaning being conveyed.
• Because natural language changes are unpredictable, computers “enjoy” obeying instructions.
• Another remarkable thing about human language is that it is all about symbols.
• The ambiguity can be solved by various methods such as Minimizing Ambiguity, Preserving Ambiguity, Interactive Disambiguation and Weighting Ambiguity [125].
• These improvements expand the breadth and depth of data that can be analyzed.

You can use various text features or characteristics as vectors describing this text, for example, by using text vectorization methods. For example, the cosine similarity calculates the differences between such vectors that are shown below on the vector space model for three terms. Natural Language Processing usually signifies the processing of text or text-based information (audio, video). An important step in this process is to transform different words and word forms into one speech form.

Statistical methods

The sets of viable states and unique symbols may be large, but finite and known. Few of the problems could be solved by Inference A certain sequence of output symbols, compute the probabilities of one or more candidate states with sequences. Patterns matching the state-switch sequence are most likely to have generated a particular output-symbol sequence. Training the output-symbol chain data, reckon the state-switch/output probabilities that fit this data best. Natural Language Processing can be applied into various areas like Machine Translation, Email Spam detection, Information Extraction, Summarization, Question Answering etc.

Sentiment analysis helps brands learn what the audience or employees think of their company or product, prioritize customer service tasks, and detect industry trends. For newbies in machine learning, understanding Natural Language Processing (NLP) can be quite difficult. To smoothly understand NLP, one must try out simple projects first and gradually raise the bar of difficulty. So, if you are a beginner who is on the lookout for a simple and beginner-friendly NLP project, we recommend you start with this one.

Natural Language Processing (NLP) Trends in 2022

The sentiment is mostly categorized into positive, negative and neutral categories. Hidden Markov Models are extensively used for speech recognition, where the output sequence is matched to the sequence of individual phonemes. HMM is not restricted to this application; it has several others such as bioinformatics problems, for example, multiple sequence alignment [128].

Therefore, for large-scale tasks, time overhead is a key factor like application promotion. Figure 5 is a schematic diagram of the anchor map-based label propagation method. In the figure, represents the training dataset that has been labeled with classes, represents the data instance, and represents the class label corresponding to . The learning system is based on the training data, from which it learns a classifier or . The classification system classifies a new input instance with the already obtained classifier to predict the class label of its output [9, 10]. Let’s look at some of the most popular techniques used in natural language processing.

Resources for Turkish natural language processing: A critical survey

In the late 1940s the term NLP wasn’t in existence, but the work regarding machine translation (MT) had started. Russian and English were the dominant languages for MT (Andreev,1967) [4]. In fact, MT/NLP research almost died in 1966 according to the ALPAC report, which concluded that MT is going nowhere. But natural language processing algorithms later, some MT production systems were providing output to their customers (Hutchins, 1986) [60]. By this time, work on the use of computers for literary and linguistic studies had also started. As early as 1960, signature work influenced by AI began, with the BASEBALL Q-A systems (Green et al., 1961) [51].

The last two objectives may serve as a literature survey for the readers already working in the NLP and relevant fields, and further can provide motivation to explore the fields mentioned in this paper. Natural language processing (NLP) has recently gained much attention for representing and analyzing human language computationally. It has spread its applications in various fields such as machine translation, email spam detection, information extraction, summarization, medical, and question answering etc.

NLP Projects Idea #4 BERT

Ritter (2011) [111] proposed the classification of named entities in tweets because standard NLP tools did not perform well on tweets. They re-built NLP pipeline starting from PoS tagging, then chunking for NER. Common NLP techniques include metadialog.com keyword search, sentiment analysis, and topic modeling. By teaching computers how to recognize patterns in natural language input, they become better equipped to process data more quickly and accurately than humans alone could do.
