Development of a parallel clustering of bilingual corpora based on reduced terms

Document clustering is a process that groups a set of documents based on their similarities. There are several studies related to document clustering. However, with the current technology, clustering bilingual text documents provides more benefits to users. There are several advantages when clustering bilingual corpus. It helps in verifying the classification and constraints of languages. Other than that, it also helps in eliminating the biased language-specific usages. However, not many works conducted that are related to clustering bilingual documents found, especially for Malay text articles. The quality of clustering bilingual text documents is highly influenced by the quality of the bag-of-word presentation of Malay text articles presented to the clustering algorithm. Hence, the aim of this study is to investigate the effects of reducing terms used in clustering bilingual text articles in English and Malay on the quality of clustering results. 500 news articles for both languages are retrieved manually from Bernama archieve and The Star website. In order to achieve this, there are three outlined objectives. The first objective of this study is to improve the stemming process for Malay language by increasing the efficiency of stemming Malay words. By improving this stemming process (0.5% error rate), the number of terms is also reduced and increases the quality of clustering results. The bag-of-word representation for Malay documents can also be improved by identifying the entities found in the text articles. By identifying the named-entity that exists in the Malay text articles, a better bag of words representation of text articles can be obtained by reducing the terms based on the named-entity recognition. The F-Measure obtain is 94.72%. Next, the second objective of this paper is to design an experimental setup that studies the effects of using different clustering linkages coupled with various proximity measurement techniques in clustering bilingual documents on the quality of clustering results. The clustering linkages include the single, complete, average and centroid linkages and the proximity measurement techniques include the cosine similarity and extend Jaccard. Based on the findings obtained, the average linkage shows ideal clustering results compared to the other clustering linkages even though the single linkage shows a lower Davies-Bouldin Index (OBI) value. This is because the standard deviation of the number of documents for all clusters is low. Not only that, this study also shows that the extend Jaccard coefficient produces a better clustering results compared to the cosine Similarity. Finally, the third objective of this study is to investigate the effects of reducing the set of terms considered in clustering English and Malay documents. A Genetic Algorithm (GA) will be implemented to reduce the number of terms used. A set of relevant terms will be selected based on the GA based terms selection process. The parallel mapping percentages show an improvement when the number of terms reduced using the GA with different mutation rate

Vitamin D, innate immunity and outcomes in community acquired pneumonia

We investigated the associations between vitamin D status, the antimicrobial peptides cathelicidin and beta defensin-2 and outcomes in community acquired pneumonia. In hospitalised patients with community acquired pneumonia, vitamin D deficiency but not antimicrobial peptide levels were associated with increased 30-day mortality. Vitamin D was not associated with levels of the antimicrobial peptide cathelicidin or beta defensin-2

Creating Product Visibility to the Bottom of the Pyramid

Emerging markets and the global dynamics growth attract the exploration of business opportunity to the bottom of the pyramid. The economic development derived to the reshaping of the business activi-ties and this is becomes very obvious especially in Asia and South American. The Bottom of the Pyramid customer has been neglected and overlooked by the industries. This paper aims to under-stand in-depth the principle and practical realities on ways to market to the bottom of the pyramid. Theoretical essay was conducted using the literature in relation to 4A marketing mix and mainly The Triumvirate Human Values Ecosystem Framework. The discussion indicates the characteristics, the misperception and opportunity of Bottom of the Pyramid market is focused. Theoretical framework for Bottom of the Pyramid marketing are developed which includes the principle, the scope and the challenges. Application of The Triumvirate Human Values Ecosystem Framework is presented through case study.

An evolutionary-based term reduction approach to bilingual clustering of Malay-English corpora

The document clustering process groups the unstructured text documents into a predefined set of clusters in order to provide more information to the users. There are many studies conducted in clustering monolingual documents. With the enrichment of current technologies, the study of bilingual clustering would not be a problem. However clustering bilingual document is still facing the same problem faced by a monolingual document clustering which is the “curse of dimensionality”. Hence, this encourages the study of term reduction technique in clustering bilingual documents. The objective in this study is to study the effects of reducing terms considered in clustering bilingual corpus in parallel for English and Malay documents. In this study, a genetic algorithm (GA) is used in order to reduce the number of feature selected. A single-point crossover with a crossover rate of 0.8 is used. Not only that, this study also assesses the effects of applying different mutation rate (e.g., 0.1 and 0.01) in selecting the number of features used in clustering bilingual documents. The result shows that the implementation of GA does improve the clustering mapping compared to the initial clustering mapping. Not only that, this study also discovers that GA with a mutation rate of 0.01 produces the best parallel clustering mapping results compared to GA with a mutation rate of 0.1

The scientific contribution of Malaysia’s researchers in the field of endodontics based on Scopus database : a bibliometric analysis

Bibliometric analyses of academic output are critical in assessing a country’s scientific performance and have ignited significant interest in recent days. However, no such study has been conducted in the field of dentistry, specifically endodontics, among Malaysia’s researchers. Hence, this study aimed to assess the publication output among researchers in Malaysia dedicating to endodontics based on the Scopus database and analyse the characteristics of selected articles as well as the publishing patterns. An electronic search based on the Scopus® database was performed from January 2001 to February 2021. Only English language articles with the first author’s affiliation from Malaysia were selected and the following parameters were extracted: title, authors, number of authors, affiliation, journal, year of publication, type of article, source, thematic categories, keywords, and number of citations. Data was analysed using Microsoft Excel software complemented by Pearson’s Chi-square and Pearson Correlation tests at 0.05 significance level. There were 119 articles included with the top-cited article received 69 citations. A total of 15 authors have 2 or more articles published, with the International Endodontic Journal published the most. Furthermore, more than half of the articles were published in Q1 and Q2 journals. Over the last two decades, there has been a substantial growth (P<0.05) in the number of articles and cumulative citations, with a significant correlation (P=0.038) between them. Besides, the Department of Conservative Dentistry and Universiti Sains Malaysia published the most articles, with the bulk of them being basic research on endodontic materials. In conclusion, the rise in scientific publications suggests an increasing interest in endodontics among Malaysia’s researchers

Paraneoplastic secretion of multiple phosphatonins from a deep fibrous histiocytoma causing oncogenic osteomalacia

Context: Literature suggests that oncogenic osteomalacia is usually caused by a benign mesenchymal tumor secreting fibroblast growth factor subtype-23 (FGF-23), but the involvement of other phosphatonins has only been scarcely reported. We have previously published a seemingly typical case of oncogenic osteomalacia. Following curative neoplasm resection, we now report unique molecular characteristics and biology of this tumor. Case Description: A 25-year-old man had been diagnosed with severe oncogenic osteomalacia that gradually crippled him over 6 years. 68Ga-DOTA-TATE positron emission tomography/computed tomography scan localized the culprit tumor to his left sole, which on resection revealed a deep fibrous histiocytoma displaying a proliferation of spindle cells with storiform pattern associated with multinucleated giant cells resembling osteoclasts. Circulating FGF-23, which was elevated more than 2-fold, declined to undetectable levels 24 h after surgery. Microarray analysis revealed increased tumor gene expression of the phosphatonins FGF-23, matrix extracellular phosphoglycoprotein (MEPE) and secreted frizzled-related protein subtype 4, with elevated levels of all 3 proteins confirmed through immunoblot analysis. Differential expression of genes involved in bone formation and bone mineralization were further identified. The patient made an astonishing recovery from being wheelchair bound to fully self-ambulant 2 months postoperatively. Conclusion: This report describes oncogenic osteomalacia due to a deep fibrous histiocytoma, which coincidentally has been found to induce profound muscle weakness via the overexpression of 3 phosphatonins, which resolved fully upon radical resection of the tumor. Additionally, genes involved in bone formation and bone remodeling contribute to the molecular signature of oncogenic osteomalacia
