Tag Recommendation Based on Collaborative Filtering and Text Similarity
Статья научная
In current social tagging system, users can freely add tags for the uploaded resources, which caused a problem that many tags could not describe the resource properly and even have some spelling errors. This problem may bring unnecessary troubles for other users who want to search this kind of resource. In this paper, a tag recommendation system based on collaborative filtering and text similarity is presented to solve the problem mentioned above. This system can automatically recommend some relevant tags for the new uploaded resources and thus the users can freely select tags from the system. Experimental results show that the recommended tags can effectively represent the contents of the webpages marked. Compared with the existing tag recommended methods, this method not only improves the accuracy of tags recommended, but also facilitates the webpage sharing and retrieval.

TakeXIR:a Type-Ahead Keyword Search Xml Information Retrieval System
Статья научная
As XML (eXtensible Markup Language) is becoming a standard widely applied in data representation and data exchange in web service. In this paper, we propose a novel approach to type-ahead keyword search in XML data, call TakeXIR. The IR-style approach basically utilizes the statistics of underlying XML data to address the following challenges in XML IR system: (1) Identify the user search intention, i.e. identify the keywords to express user interests and identify nodes user wants to search for and search via. (2) Resolve keyword ambiguity problems: synonyms and polysemy exist in natural language, and a keyword can appear as the text values or tag value of different XML node and carry different meanings.

Text Analyzer for Competitive Examination
Статья научная
Competitive examination provide a platform to the user for gauging their verbal and literature skills. The tools available currently only provide some simple feature regarding text processing such as spelling correction and providing different synonyms of the selected words. A complete assessment is not done for the user’s abilities and relevant details related to the context are not taken entirely into consideration. The following paper proposes a way to implement Natural Language Processing on text to provide feedback to the user for their competitive examinations. The assessment of the text will be done according to the parameter such as grammar, vocabulary; relevance to the context. Some applications for web and mobile platform are available to offer assessment of English language essay but limited academic research available to validate research work in this domain. This work is effort to address requirement of text analyzer for English language evaluation methods incorporating natural language processing.

Text Steganography using Daily Emotions Monitoring
Статья научная
Early in 2008, it was emphasized that sending messages through public networks will draw the attention of third parties such as attackers, perhaps causing attempts to break and reveal messages. Thus, cryptography was initially used to send a text message by producing cipher text. Although cryptography provides confidentiality for sent message, but the cipher text that is generated appears nonsense for the attacker, which leads to being identified as the sensitive information. In order to overcome this problem, this paper introduces a novel mobile steganography technique, based on using emoticons to deliver sensitive information as a daily emotion monitoring application. Based on achieved result, 88 characters can be embedded and sent to the recipient successfully in a hidden way.

This paper proposes multiple optimal combinations of renewable and nonrenewable energy systems for Nilphamari, Bangladesh. The Nilphamari relies mainly on on-grid electricity system. Therefore, the optimal combination of hybrid energy systems related to renewable and nonrenewable options is proposed to mitigate grid dependency. This hybrid energy system generates electricity for the consumption loads of the project area in which the natural resource potentials like solar, wind, hydro, and diesel are available. All power sources and resources data are included in the Homer software carefully. Finally, the Homer software is applied for viable techno-economic investigations especially cost of energy (COE) and net present cost (NPC) for the proposed hybrid system in Nilphamari, Bangladesh. The optimization result indicates that $0.224/kWh is the minimal COE. The proposed system has an operating cost of $16,156.16, a COE of $0.241/kWh, an NPC of $2,961,790.00, and a CO2 output of 3,373 kg per year. The proposed system's legitimacy, as determined by the LCOE and the NPC, was confirmed by optimization analysis. Within a few years of the project's lifetime, the system is estimated to pay for itself completely. The evaluations yielded the best system configurations, hybrid system costs, fuel savings, and CO2 emission reductions.

The Cell Cycle Model: A Comprehensive Review and Extension Based on Machine Learning
Статья научная
The cell cycle is a conserved process comprising of an organized series of interdependent and cross regulatory events that lead to controlled cell growth and proliferation. Genomic and volume regulatory processes are of special interest as they decide the fate of cell cycle. Signaling cascades including MAPK, PI3K, Sonic Hedgehog, Wnt and NOTCH signaling pathways are few well known conventional players contributing in controlling the cell cycle progression through different phases by expressing certain proteins. Moreover, the unconventional volume regulatory players exert influence by regulating membrane potential that is determined by ions influx or efflux across the plasma membrane via ion channels, controlling water movement and ultimately contributing to volume increase in growth phases of the cell cycle. Both of these players are interlinked, therefore, in order to establish a better understanding of the interdependence of these players, principles of machine learning were applied on data obtained on cell cycle. The data was processed by using neural networks and it shows that a significant understanding of conventional regulators is available in the literature and it has been under the limelight as well. However, when it comes to unconventional volume regulatory players, a limited understanding is available. Moreover, the precise role of each component and its interdependence with other is not yet fully understood. Due to which, they are not clearly evaluated for their potential role as cell cycle control elements for therapeutic purposes. Therefore, this study aims to summarize the data on cell cycle that is obtained through machine learning and to discuss the advances in cell cycle modelling mechanisms and designs that are based on different mathematical algorithms. Thus, this review will provide a basis to clearly understand and interlink the discoveries on cell cycle so that a comprehensive cell cycle model could be built which, if manipulated can be used for therapeutic purposes by identifying the least explored regulatory control elements.
