NSURL-2019 Task 7 feature is developed to provide a comparison between different approaches used in NER and develop a standard tested. According to (Taghizadeh et al., 2020). The approaches are used to show the terms used to specify NER in Farsi texts. Additionally, the testbed developed by the NSURL-2019 Task 7 feature is used for future research work concerning NER in Farsi.
According (Seok et al.,2016), the word embedding feature for named entity recognition is used in various ways. The feature is used to show the words used in a sentence and learning algorithms of natural language processing (NLP). The embedding methods used include the CCA, Word2Vec and GloVe. According to research and testing, CAA and Word2Vec are the main embedding methods used and with a rating of more than eighty percent. The use of word embedding enables the user to obtain better results since the feature shows the similarities between different words. Word embedding features use a one-hot representation to change words into vectors. Additionally, the feature groups the same word because they consist of the same vectors (Seok et al., 2016).
The feature does not go through data scarcity, although the one-hot representation cannot process words outside the labeling training data. The glove works under no supervision in getting vector representation. On the other hand, Word2Vector is based on the neural network, where the feature’s primary aim is to group words with the same characteristics into one vector space. Word2Vector uses the continuous bag-of-words (CBOW) architecture to predict words where the words are arranged according to history. CBP uses large data in learning hence cannot be used in other types of neutral network bags. The word embedding feature uses skip-gram used to average log probability and popular for its accuracy.
Additionally, the Robust Lexica feature for NER is used to minimize the need of hand-designed features. The lexica features are essential and with less supervision. Other types of features are, the bidirectional LSTM and learning orthographic features used in bi-directional LSTM.
The chemical named entity recognition, as proposed in (Luo et al., 2018), the feature is used to detect chemicals in biomedical literature. The chemical NER depends on the NLP and other literature resources, which has been challenging. The feature identifies proteins and disease, providing better results, similar features in a document and related characteristics in different documents. The chemical NER provides better results in Bio Creative V chemical-disease relation (CDR) and Bio Creative IV CHEMDNER. The feature is applied in deep learning methods by combining words and characters (Luo et al., 2018).
Additionally, the feature evaluates the impact of POS as a traditional feature. Other features used together include the domain resource feature and linguistic feature. The models used in this feature include the BiLSTM-CRF and Att-BiLSTM-CRF model. The named entity recognition has very limited research because, during searching, the entity tag is used due to the pre-indexing corpus. It is challenging to find data concerning NER because the named entity consists of other name entities.
Elicitation requirements in the software development cycle are very important. The author depicts that various approaches are used in the elicitation process requirements to enhance project development. The elicitation process used the functional and non-functional requirements methods, which involve physical and other requirements such as maintainability. The elicitation process provides precise information. The different software development lifecycles (SDLC) consist of requirements of engineering, integration and testing, maintenance, design and implementation. Moreover, the component assesses the effect of POS as a conventional element. Different highlights utilized together incorporate the space asset include and phonetic component. The models utilized in this component incorporate the BiLSTM-CRF and Att-BiLSTM-CRF model. The named substance acknowledgment has exceptionally restricted examination on the grounds that, during looking, the element tag is utilized because of the pre-ordering corpus. It is trying to discover information concerning NER on the grounds that the named substance comprises of other name elements.
Elicitation necessities in the product improvement cycle are vital. The creator portrays that different methodologies are utilized in the elicitation cycle prerequisites to improve project advancement. The elicitation interaction utilized the utilitarian and non-practical necessities strategies, which include physical and different prerequisites like viability. The elicitation cycle gives exact data. The diverse programming advancement lifecycles (SDLC) comprise of necessities of designing, combination and testing, upkeep, plan and execution.
The software engineering industry has improved tremendously in market-driven product development. The industry is creating a web-based feature for capturing Shock Pulse Method knowledge. The knowledge gathered is stored in the method base waiting for assessment, enhancing improvement through the OME. Knowledge management has been used in all software development projects and different aspects, for instance, in technical, organizational and social-cultural aspects. The online method engine can be used to relieve the software improvement steps through the provided diagnostic methods.
According to the author, the neural network models are better and accurate compared to other representation models. The modification and improvement, such as the neural network architecture, have brought about most benefits, especially in providing quality or word presentations and prefixes and syntaxes in the beginning and at the end of each word. NER’s architecture combines several features, for example, the orthographic, morphology, and various machine learning methods to improve quality and extract meaningful and accurate texts. The neural network for named entity recognition is still advancing and integrating the advancing technology to enhance deep learning and lead to development or research projects (Yadav and Bethard, 2019).
