the importance of BangIa image captioning is rooted in the need to bridge the gap between visual content and textual descriptions in Bengali, thereby facilitating more accessible and inclusive technologies for Bengali-speaking individuals. Image captioning entails the creation of textual descriptions for images through the application of deep learning techniques that combine methodologies from computer vision and natural language processing to accurately recognize and depict visual content. this study presents an innovative methodology that employs EfficientNetB4 and ResNet-50 architectures for the extraction of features. the selection of these models followed a comprehensive evaluation of numerous alternatives, as they exhibited exceptional performance, rendering them well-suited for the objectives of this investigation. A pivotal contribution of this analysis is the introduction of the newly established BangIa View dataset, designed specifically for BangIa captioning tasks, used alongside the widely recognized Flickr30k dataset. the empirical results reveal that EfficientN etB4 surpasses ResN et-50, attaining a BLEU score of 0.54 after merely 10 training epochs, underscoring its efficacy in generating coherent BangIa captions. these outcomes not only illustrate technological progress but also highlight the potential of this methodology to stimulate innovations that promote linguistic diversity and improve user experiences in domains such as accessibility and digital communication.

In order to detect misrecognitions that may result from a mismatch between training and testing data. we use a confidence measure (CM) that collects a set of features during recognition and from the N-best list that is output by the recognizer. A neural network (NN) then calculates the probability that the utterance was recognized correctly based on these features. Since for misrecognized utterances the resuiting phoneme alignments are often erroneous, we introduced some new features that are based on phoneme durations. the durations found by the recognizer are compared to the durations present in the training data base and the resuits of these comparisons serve as input for the NN. A great advantage of the duration-related features is that they are independent of the recognizer in contrast to e.g. acoustic scorebased features. We also use some score-related fearures that have proven to be useful in the past. Simultaneously with determining the confidence for a recognition resilt, we try to detect if in case of a misrecognition the utterance was an out of vocabulary (OOV) utterance. Using the complete set of 46 features we can achieve a correct classification rate of 90%. the word error rate can be reduced by 92% at a false rejection rate of 5.1% on a test task that consists of 35 speakers and includes more than 50% OOV utterances. OOV words were detected correctly in 91% of the cases. the presented CM is also used in a semi-supervised speaker adaptation scheme.

Sentiment analysis employs natural language processing, computational linguistics, and other textual analysis approaches to locate and extract subjective information to assess the text's conveyed attitude or emotional state. the prevalence of internet-based media and online businesses encourages extensive user engagement. Individuals frequently express their opinions, thoughts, ideas, attitudes, feelings, and more using familiar languages on various social media platforms. the majority of individuals tend to articulate their opinions using a combination of languages, often incorporating English with their native tongue. the lack of annotated code-mixed data poses a significant problem for automated sentiment analysis in languages with limited resources such as Bangla. To tackle this challenge, we aim to gather code-mixed content in Bangla and English. Subsequently, we plan to utilize data augmentation techniques to expand the dataset. Following this, we aim to conduct a comparative analysis by employing a variety of machine-learning techniques. this research delves into four common machine learning techniques—Support Vector Machine (SVM), Decision Tree (DT), Stochastic Gradient Descent (SGD), and Random Forest (RF)—employing feature extraction named TF-IDF methods. the experimental results indicate that Random Forest with TF-IDF gained the highest accuracy, reaching 83%, outperforming other techniques.

Natural language processing (NLP) is increasingly drawing researchers’ attention to mine for valuable knowledge in the massive literature arising in our technological era. Text mining is one of the NLP tools that can take the lead over manual curation of articles from different medical databases. It offers appreciable help by automating the whole information extraction process to get the required information saving effort and time. As Mobile Health (mHealth) for breast cancer patients is showing a clear positive impact on their treatment and recovery journey, text mining techniques can help in the continuous tracking of related research articles to figure out the drawbacks and highlight future directions. therefore, this article proposes a model that initiate a deep search to curate articles dataset using National Center for Biotechnology information (NCBI) database applying five different queries. the model preprocesses the curated dataset to remove outliers and extract the target articles only. In addition, it analyzes the articles’ titles to extract required information. Total number of retrieved articles was 610 that are further reduced to 13 after the applied filtration steps. Two of which are review articles that are concerned with effect of mobile apps on patients undergoing chemotherapy which is a cancer critical stage. the retrieval process took from few seconds to several minutes according to the number of articles related to the entered query, while the preprocessing stage is achieved in one second.

A fake news spreader is a person who deliberately shares misleading information to misguide people. Fake news spreaders can be considered a potential threat to our society. Any misleading information floating in social media can create a serious misconception in society. It can damage the reputation of a person and create cybersecurity threats. To ensure a safe and sound social networking environment for everyone, it is inevitable to detect fake news spreaders. Numerous state-of-the-art approaches have been done to address this issue. they employed several classification algorithms to detect the fake news spreaders. Usually, social media data often lack proper grammar due to noise and informal language. In most of the prior work, the authors did not use the proper text preprocessing techniques which leads to poor performances. To solve this problem, we describe our proposed framework which includes extensive text preprocessing techniques and statistical features along with the stochastic gradient descent (SGD) classifier on top to detect the fake news spreader efficiently. We choose SGD because of its capability to handle large datasets as well as the stochastic phenomenon helps to escape local minima and performs better generalization in complicated optimization scenarios. Experimental results on the benchmark PAN 20 fake news spreader dataset show that our proposed approach outperformed most of the prior works with a 76.50% accuracy thus validating its effectiveness.

Joint extraction of entities and their semantic relationships to form factual triples from unstructured text is a fundamental task in information extraction. However, existing methods either ignore the interactions between relationships and entities or extract the subjects and objects in a fixed sequential order, which makes these approaches too sensitive to the extraction results of subjects. To address the two issues, we propose a pre-relation bidirectional joint extraction model (PRBJE). Specifically, we first detect potential relationships from the sentence to assist in the subsequent extraction of head and tail entities. then, we extract all possible entity pairs maintained in the text using two complementary directions: extracting the tail entity based on the head entity and vice versa. Finally, we assign relationships to all entity pairs by a biaffine model, thereby forming complete relational triples. Extensive experimental results demonstrate that our model outperforms state-of-the-art methods, with improved F1 scores across four public datasets, particularly achieving gains of 0.9 and 0.7 on NYT and webNLG, respectively.

the application range of communication robots could be widely expanded by the use of an automatic speech recognition (ASR) system with improved robustness for noise and for speakers of different ages. In this paper, we describe an ASR system which can robustly recognize speech by adults and children in noisy environments. We evaluate the ASR system in a communication robot placed in a real noisy environment. Speech is captured using a twelve-element microphone array arranged in the robot chest. To suppress interference and noise and to attenuate reverberation, we implemented a multi-channel system consisting of an outlier-robust generalized sidelobe canceller (RGSC) technique and a feature-space noise suppression using MMSE criteria. Speech activity periods are detected using GMM-based end-point detection (GMM-EPD). Our ASR system has two decoders for adults' and children's speech. the final hypothesis is selected based on posterior probability. We then assign a generalized word posterior probability (GWPP)-based confidence measure to this hypothesis, and if it is higher than a threshold, we transfer it to a subsequent dialog processing module. the performance of each step was evaluated for adults' and children's speech, by adding different levels of real environment noise recorded in a cafeteria. Experimental results indicated that our ASR system could achieve over 80 % word accuracy in 70 dBA noise. Further evaluation of adult speech recorded in a real noisy environment resulted in 73 % word accuracy
