Open bug repositories prove to be very helpful in Software Engineering, since they provide a platform for developers and end-users to report bugs. Along with summary and description, reporters are also expected to assign a component name. Without knowledge of internal structure of a project often a wrong component name is assigned. These incorrect naming may delay process of bug related activities. Pre-requisite to develop any automated component prediction system is to extract relevant features from bug reports. Bug reports are in natural language, therefore, before using them for training process, a vector space of relevant features is built. TFIDF Weighting and Topic Modeling techniques have been examined in this work w.r.t. their ability to choose selective terms from bug reports. This work has done a comparative analysis of two above mentioned preprocessing techniques along with three classifiers-Naive Bayes, SVM and C4.5 in context of correct component prediction.

Probiotics (originated from Greek words pro and bios which means for life) are beneficial microorganisms and their products, having the beneficial effects on the host. It is being recently used in aquaculture in order to control diseases and also treated as supplements for improving growth and in some cases as a mean of replacing antimicrobial compounds. Besides, enhancing growth performance and improving haematological parameters of fishes, it also improves water quality which is considered as most important for freshwater fish habitat as fishes are extremely sensitive to changes in environmental factors viz., temperature, water salinity, oxygen level etc. Thus, this review summarizes current studies regarding the effects of probiotics on growth performance, haematological parameters of various fishes and water quality.

In conquest to attain the goal of zero hunger as well as tackling the problem of malnutrition worldwide, fish proves to be one of the best functional food to humans. Along with the sense of good taste to humans, it ensures great nutritional value at an affordable price. Fish food plays an active role in providing nutrients to the body that are directly involved in metabolic activities. It is enriched with high quality protein containing all the essential amino acids, omega-3 polyunsaturated fatty acids including eicosapentanoic acid and docosahexaenoic acid. Also, it provides wide variety of micronutrients involving vitamins (fat soluble vitamins and several members of vitamin B complex) and minerals. Also, these have significant protective effects against the occurrences of several diseases such as cancer, cardiovascular diseases, inflammatory diseases, retinopathy, diabetes, arthritis and some other acute or chronic diseases. The bioactive peptides from fish food are reported for their positive effect on humans. Therefore, fish is an optimal choice of food to humans as it helps in their growth, development and maintenance of good health. However, care should be taken during processing of fish or fish products as the inappropriate handling can deteriorate the nutritional quality of the food.
