Empowering Recommendations with NLP: Exploiting Textual Reviews for Enhanced Rating-Based Systems

This research paper proposes a rating-based recommender system that leverages Natural Language Processing (NLP) techniques to enhance the accuracy and effectiveness of recommendations. Traditional recommender systems primarily rely on numerical ratings provided by users to make predictions. However, these ratings often lack detailed information about user preferences and suffer from sparsity and inconsistency issues. By incorporating NLP, we aim to extract valuable insights from textual reviews and improve the recommendation process. Our system utilizes sentiment analysis, topic modelling, and text embeddings to capture the implicit information in reviews and generate more personalized and context-aware recommendations. The experimental results demonstrate the superior performance of the proposed rating-based recommender system compared to conventional approaches

Changes in proximate, biochemical and microbiological characteristics of dried Labeo gonius fillets during storage at room temperature

An experiment was carried out to assess the changes in proximate, biochemical and microbiological characteristics of dried Labeo gonius fillets stored at room temperature. Moisture, crude protein, total lipids, nitrogen free extract (NFE) and ash content of the product were 77.46, 17.94, 2.2, 1.59 and 0.81%, respectively. Total volatile base nitrogen (TVB-N) content was found below the range suggested by various researchers for fish and fish products. Total plate count (TPC) of 1.54 × 104 cfu/g was observed and the dominant genera of bacteria were Pseudomonas spp., Micrococus spp., Streptococus sp., Barillus spp. and Vibrio spp. found in higher percentage. There were no appreciable changes in salted dried L. gonius stored in two different packaging materials. Total lipid showed a progressive decrease in the entire salted dried sample during the storage period. An increase in TVB-N was found in dried products stored in gunny bag. The packaging material used had a little effect on peroxide formation. The most common fungi found during storage in the specimen studied were Aspergillus sp. and Pencellium.Keywords: Labeo gonius, fish, TVB-N, lipid, moistureAfrican Journal of Biotechnology Vol. 12(20), pp. 2997-300

The H(n)-move is an unknotting operation for virtual and welded links

An unknotting operation is a local move such that any knot diagram can be transformed into a diagram of the trivial knot by a finite sequence of these operations plus some Reidemeister moves. It is known that the H(n)-move is an unknotting operation for classical knots and links. In this paper, we extend the classical unknotting operation H(n)-move to virtual knots and links. Virtualization and forbidden move are well-known unknotting operations for virtual knots and links. We also show that virtualization and forbidden move can be realized by a finite sequence of generalized Reidemeister moves and H(n)-moves

Growing Importance of E-Commerce in Global Market

We can define e-commerce simply as doing business electronically.  In this world of new technology businesses need to accommodate to the new types of consumer needs because it is very important for business success. E-commerce enables organization to improve their competiveness. It crosses geographic boundaries, save time and cost. There are many positive impact of e-commerce on many areas and disciplines of business management studies such as marketing, finance, accounting, production and operation management. In our paper we have explained about e-commerce and its different types. We have also explained the future growth and limitations of e-commerce.

Biochemical modulation in male specimens of Channa punctatus (Bloch) under different habitats and seasons

Studies were undertaken to identify the changes in biochemical parameters including water content, lipid and protein in tissues of liver, testis and muscle of Channa punctatus under natural and captive conditions along with physico-chemical parameters for the period January to December, 2008. Result shows that values of lipid in captive condition in muscle, liver and testis ranged from 1 to 4, 1.98 to 5.57 and 1.25 to 4.40%, respectively while in natural habitat, values ranged from 1 to 5, 1.94 to 5.16 and 1.21 to 5.13%, respectively. Water content in captive condition was observed to be in the range of 74.72 to 80.73, 73.97 to 76.92 and 75.56 to 77.97%, respectively and in natural habitat it varied from 72.65 to 80.70, 71.61 to 76.89 and 72.41 to 77.94%, respectively. An increase in water content was observed towards maturation in testis. Protein content in muscle under captive and natural habitat was in the range of 15.97 to 19.37 and 16.70 to 19.40%, respectively. All parameters showed a significant variation (p<0.01) and significant correlation (p<0.01) among the muscles, liver and testis in specimens under captive as well as natural habitat. Peak spawning period in nature was observed during May to August in captive condition indicating that gonadal development and its cyclicity is influenced by the physico-chemical parameters, food and feeding conditions, environmental factors and other stresses. This study shows that the variation in biochemical changes are influenced by variation in seasons due to physico-chemical parameters of the habitat and perhaps the niche.Key words: Habitat, Channa punctatus, testis, biochemical change, physico-chemical parameter

Effect of Nanosilica and Carbon Nanotubes Addition on Mortar Mechanical and Durability Properties

Nowadays, nanomaterials are being extensively used in civil engineering works for improving their quality. Improved compressive strength, flexural strength, modulus of elasticity, and good durability performance of nanocomposites attracted the researcher's interest in understanding these nanomaterials’ behavior in cementitious composites. In the present paper, mechanical and durability properties of 1.0 wt% nanosilica (NS) and four different types of 0.3 wt% carbon nanotubes (CNTs) admixed cement mortar was assessed at 28, 56, 90 and 120 days under sulphate water curing. The outside diameters of CNTs are 10-20 nm and 30-50 nm, each type are un-treated and treated with COOH group, respectively. Results showed that flexural and compressive strength was improved for mortar sample admixed with nanomaterials than normal one. Also, nanomaterials came up as a good solution against abrasion and sulphate attacks. The durability is also enhanced for such mortar samples as the density increases, reducing the porosity and water absorption capacity. Resistivity results indicated negligible to low risk of corrosion, thus increasing the durability of these mortar samples. Overall, the sample formed with treated CNTs and 30nm – 50nm outside diameter gave better results than control specimen and other admixed mortar. Scanning Electron Microscopic  images were in strong correlation with the experimental results

Genetic diversity analysis of Labeo gonius (Hamilton, 1822) in three different reservoirs of Uttarakhand by using allozyme marker

The present population genetic study was carried out to identify basic genetic structure of Labeo gonius from three different sized reservoirs viz., Dhaura, Baigul and Nanak Sagar reservoir of Uttarakhand by applying allozyme markers. The allozyme analysis was conducted for 18 enzymes but only 10 enzymes showed their presence with scorable activity. All ten allozymes yielded overall 19 scorable loci, out of which 11 loci were found to be polymorphic in the population with a percentage of 57.89. Genetic diversity parameters, that is number of polymorphic loci, the mean number of alleles per locus, observed (HO) and expected heterozygosity (He), fixation index (FIS) and genic differentiation were estimated by using software GENEPOP Ver.3.4 indicating high level of genetic diversity in stocks of all three reservoirs of L. gonius being more heterozygous in Nanak sagar followed by Baigul and Dhaura reservoirs. FST for overall populations ranging from 0.01 to 0.18 indicate moderate genetic differentiation as per Wright’s criteria. The allozyme analysis in L. gonius showed that these populations are moderately differentiated from each other and likely to be associated with small gene exchange which is responsible for weak sub-structuring of stocks in the three reservoirs.Keywords: Allozyme, Labeo gonius, genetic diversity, population geneticsAfrican Journal of Biotechnology Vol. 12(19), pp. 2532-253
