Enhanced User-driven Ranking System with Splay Tree

Abstract

E-learning is one of the information and communication technology products used for teaching and learning process [35]. An efficient and effective way to construct trust relationship among peer users in e-learning environment is ranking. User-driven ranking systems are b ased only on the feedb ack or rating provided b y the users. In [46][47][48] the authors provide a variety of trust and reputation methods. Certified Belief in Strength (CBS) [45] is a novel trust measurement method b ased on reputation and strength . In [38] author presents a recommendation system b ased on the relevant feedb ack review to predict the user's interests, that are ranked b ased on the recommendations history they provide previously. Users with higher rating ob tain high reputation compared to less scored users. In question answering web sites like StackOverflow, new or low scored users are ignored b y the community. This discourage them and their involvement with the community reduces further down, as power law states, alleged low users are pu shed to the b ottom of the ranking list. Avoid this condition b y encouraging less reputed users and prevent them from moving further down in ranking level. Thus, low reputed users are provided with few more chances to participate actively in the e-learning environments. A splay tree is a Binary Search Tree with self-b alancing skill. The splay tree b rings the recently accessed item to the top of the tree, thus active users are always on the top of the tree. A splay tree is used to represent user's ranks, and to semi-splay low ranked users again in the tree thus preventing them from further drowning in the ranking list. The focus of this research work is to find and enhance low reputed users in reputation system b y providing few more chances to take part actively in the e-learning environment using the splay tree. Normalized discounted cumulative gain (NDCG) acts as a decision part for identifying drowning users.

Expert Recommendation Through Tag Relationship in Community Question Answering

“…These metadata are used to identify different technical/academic/general inclinations since most CQA questions posted contain multiple tags where the co-occurrence/repetition of tags is an essential means for identifying users' interest in multiple domains. This is supported in a particular study demonstrating the explicit relationship between users and their domain interest in the co-occurrence of tags through relevant posts [22]. Hence, in a bid to investigate similar specific domain interests amongst users, the proposed method in the current study deconstructs the co-occurrences of tags from the user's previous archive, realizing that the compiled analysis of tag co-occurrences for each user highlight user intent and their interest [23].…”

“…These variations are considered attributes of the CQA website [17,18]. In these studies, researchers built user profiles based on various attributes in CQA such as title, questions, answers, tag, badges, number of visits, voting, location, last login and score which can be quantitatively used to measure expert recommendation [19,20,21,22].…”

Scientific Publication Management Transformation In Disruption Era

“…According to JayashreeR, good language and grammar skills are needed, as well as understanding mature knowledge in accordance with the topic of scientific work in scientific paper writing. Add additional information and facts about one side of the power of arguments to support content arguments in papers [2]. As a reference for search engines and scientific articles in writing scientific papers, this is where there are unlimited sources of information.…”

The strategy of enhancing article citation and H-index on SINTA to improve tertiary reputation

“…According to Jayashree R. [1], it takes good language and grammar skills, as well as a mature understanding of knowledge according to the topic of scientific work in writing a scientific paper. To support the content of the argument in the paper it is desirable to add additional information and facts as one side of the power of an argument [1]. This is where one of the benefits of internet existence as an unlimited source of information.…”
