Comparative Analysis of Contextual Relation Extraction based on Deep Learning Models

Contextual Relation Extraction (CRE) is mainly used for constructing a knowledge graph with a help of ontology. It performs various tasks such as semantic search, query answering, and textual entailment. Relation extraction identifies the entities from raw texts and the relations among them. An efficient and accurate CRE system is essential for creating domain knowledge in the biomedical industry. Existing Machine Learning and Natural Language Processing (NLP) techniques are not suitable to predict complex relations from sentences that consist of more than two relations and unspecified entities efficiently. In this work, deep learning techniques have been used to identify the appropriate semantic relation based on the context from multiple sentences. Even though various machine learning models have been used for relation extraction, they provide better results only for binary relations, i.e., relations occurred exactly between the two entities in a sentence. Machine learning models are not suited for complex sentences that consist of the words that have various meanings. To address these issues, hybrid deep learning models have been used to extract the relations from complex sentence effectively. This paper explores the analysis of various deep learning models that are used for relation extraction.Comment: This Paper Presented in the International Conference on FOSS Approaches towards Computational Intelligence and Language TTechnolog on February 2023, Thiruvananthapura

Comparison of biopolymer finishing with functional finishing on wool fibre

Wool: cotton union fabric has been applied with chitosan biopolymer to impart shrink-proof finish and its performance is compared with two synthetic polymer finishes. Results show that chitosan forms thin film on the surface of wool fibre as in synthetic finishing polymer. The diffusion of chitosan biopolymer inside the wool fibre matrix is found to be better than synthetic polymer, which is confirmed by the cross-sectional view of finished wool fibre. It is concluded that chitosan biopolymer could be preferred over other synthetic polymer to prevent shrinkage of woollen textiles.

A study on the thermophysiological and tactile comfort properties of silk/lyocell blended fabrics

Certain investigations on the thermophysiological and tactile comfort properties of silk/lyocell blended fabrics have been carried out. A series of yarns were produced as 100% silk (S 100), 75% silk and 25% lyocell (S/L 75:25), 50% silk and 50% lyocell (S/L 50:50), 25% silk and 75% lyocell (S/L 25:75) and 100% lyocell (L 100) and converted to woven fabrics keeping the same fabric set. FTIR study on silk, lyocell and silk/lyocell blended fabrics show the characteristic functional groups for the respective fabrics. The effects of blend compositions on thermophysiological and tactile comfort properties were examined and the results show that thermal resistance of the fabrics containing silk has a higher value in comparison with lyocell-rich blends. Water vapour permeability, absorbency and wickability for lyocell and lyocell-rich blends are found to be superior as compared to 100% silk fabrics. With respect to drape, bending length and crease recovery the lyocell rich fabrics are good in comparison with 100% silk fabrics. The results are discussed using one way ANOVA with 5% significant level.Keywords: silk, lyocell, blending, comfort, eco-friendly

Machine Learning Approach for Cancer Entities Association and Classification

According to the World Health Organization (WHO), cancer is the second leading cause of death globally. Scientific research on different types of cancers grows at an ever-increasing rate, publishing large volumes of research articles every year. The insight information and the knowledge of the drug, diagnostics, risk, symptoms, treatments, etc., related to genes are significant factors that help explore and advance the cancer research progression. Manual screening of such a large volume of articles is very laborious and time-consuming to formulate any hypothesis. The study uses the two most non-trivial NLP, Natural Language Processing functions, Entity Recognition, and text classification to discover knowledge from biomedical literature. Named Entity Recognition (NER) recognizes and extracts the predefined entities related to cancer from unstructured text with the support of a user-friendly interface and built-in dictionaries. Text classification helps to explore the insights into the text and simplifies data categorization, querying, and article screening. Machine learning classifiers are also used to build the classification model and Structured Query Languages (SQL) is used to identify the hidden relations that may lead to significant predictions

A study on the functional properties of silk and polyester / lyocell mixed fabric

ABSTRACT Silk is one of the valuable fibers in textile industry. It is used for delicate applications in many areas such as sarees, suitings, curtains and luxurious interiors. To diversify the properties and usages silk is mixed with polyester and lyocell. The fabric is dyed with natural dyes (kum kum, indigo, barberry) as well as synthetic dyes (reactive dye (H), reactive dye (M) and sulphur dye). This mixed fabric is compared with 100% silk for some of the basic properties like absorbency, water retention, wicking, water vapour permeability, air permeability, K/S values, colour fastness and antimicrobial property. The silk mixed fabric gives the appreciable results with the 100% silk fabric

Island Flaps in Plastic Surgery

INTRODUCTION: Reconstruction in Plastic Surgery has been revolutionised with the use of flaps with a intact blood supply.Today the reconstuctive plastic surgeon faced with a soft tissue defect has a plethora of options. Major advances in the field of plastic surgery have been made possible by the use of muscle flap,musculocutaneous flap,fasciocutaneous flap and various techniques of microvascular composite tissue transplantation. Application of precise knowledge of anatomy of the skin, muscle, bone and fascia in planning the reconstructive procedure, the surgeon has the ability to restore the form and function in congenital and acquired defects in most topographic region. Modifications and refinements in flap design offer considerable variety and versatility in the technique available for reconstructive surgery. With application of principles of flap design and technique it is possible to simplify the approach to the reconstruction of surgical defect. Cover form and function are the three most important factors in determining the successful outcome. By thorough analysis of each individual surgical defect the most appropriate method of reconstruction can be selected. Island flaps are designed on the principle of transfer of tissue without an intact epitheliazed skin pedicle. Further refinements in design and techniques has reached a point where flaps are transfered on vascular and neurovascular bundles. AIM OF STUDY: The main objectives of this clinical study are 1. To study the role of island flaps in modern plastic surgery. 2. To discuss the types,anatomical regions,planning and tecniques of execution of island flaps 3. To analyse the merits and demerits of island flaps 4. To study the post operative management and complications 5. To assess the outcome of reconstruction on the basis of form, function and aesthesis. 6. To discuss the emerging trends and future prospects for island flaps in reconstructive surgery. MATERIALS AND METHODS: Materials: This work includes the study of 30 patients who underwent reconstruction using island flaps for resurfacing defects from head to foot due to trauma ,congenital lesions or surgical extirpation of tumour. The patients who were admitted to Plastic Surgery, Surgical Oncology and General Surgery wards at Government Rajaji Hospital, Madurai, were studied between September 2005 – April 2008. Methods: The methods include obtaining information from patients, thorough clinical examination and doing necessary investigations for management. All informations were entered in a proforma specially designed for this study. Methodology: The patient’s name,age, sex, history of presenting illness and its duration was obtained. Past history of chronic medical and surgical illness noted. Personal history like smoking, alcohol consumption and diet pattern were obtained. Detailed physical examination of the defect was made and tissue diagnosis was recorded and reconstruction planned accordingly. Basic investigations like blood Hb estimation, urine examination, blood sugar and renal parameters like urea, creatinine were done. Serum protein levels were assessed. X ray chest and ECG were taken. Doppler study was performed to identify and preoperatively mark the perforator vessels in selected cases. Cardiac status was examined by specialist of our institution. Diabetic patients were treated on Diabetologist opinion. Based on the above investigations, patients were assessed for general anaesthesia and managed surgically. Intraoperative, post operative complications were noted and managed accordingly. All the patients were reviewed in our OP department. OBSERVATIONS: Reconstuction using flaps are performed regularily in all operation theatres for defects from head to foot. Out of these 16 interesting island flaps excuted in 60 patient during the period of Sep 2005 to Jan 2008 and were taken up for this study. All cases were in the age group from 6 – 80 years. 60 % cases were male and 40 % were female in our study. Majority of the defects were either due to trauma or post tumour resection. In this study majority of the defects were of the trunk, followed by head and neck region. In this study, an almost equal distribution of all types of flaps were performed. In this study, 4 cases of sensory flap which included Neurovascular island flap, saphenous artery and medial plantar island flap were performed. Almost half of the donor sites in our study were closed primarily. In this study, 13% of patients had haematoma. Wound dehiscence, infection and graft loss were seen in 6.6% each. One patient had flap necrosis which was only partial thickness. As late complications, 13 % each of hypertrophic scar, contour deficit and functional disability like pseudomotor skin changes were noted. 80 % of patients has an excellent aesthetic outcome. CONCLUSION: 1. Island flaps are based on reliable anatomically defined vascular territory with in the flap – blood supply is reliable and robust. 2. The reliability and volume of tissue that can be placed into the defect is markedly greater than any random pattern flap. 3. Delay procedure was unnecessary when moblizing large tissue volumes in a single procedure based on the direct circulation. 4. Arc of rotation is more compared to pedicle flap 5. Inset is complete and satisfactory. 6. Local tissue match - similarity in skin color, texture form contour and aesthesis etc., is excellent. 7. Restoration of function whether motor or sensory is possible in certain flaps. 8. Single stage procedure 9. Most of the donor size can be closed primarily, donor site morbidity also negligeable 10. As good as free flap and minimize the indication for free flap
