Recommendation based on object typicality.

In this paper, we investigate recommendation systems from a new perspective based on object typicality and propose a novel typicalitybased recommendation approach. ... Current recommendation methods are mainly classified into contentbased, collaborative filtering and hybrid methods. These methods are based on similarity measurements among items or users. ... CONCLUSION In this paper, we investigate the recommendation system from a new perspective and present a novel recommendation method based on object typicality. ...

In item based CF method, main task is to provide a user with the recommendation on an item based on the item with high correlations. ... Here, we have proposed novel efficient Expectation Maximization (EM) Clustering and typicality-based collaborative filtering recommendation (EmTyCo). ... All these works focus on developing methods to calculate object typicality in concepts. There is no work on integrating typicality in collaborative filtering recommendation. ...

This paper proposes the implicative rating measure developed on the typicality measure. The paper also proposes a new recommendation model presenting the top N items to the active users. ... The proposed model is based on the user-based collaborative filtering approach using the implicative intensity measure to find the nearest neighbors of the active users, and the proposed measure to predict ... Typicality To measure the typicality of an object i for the formation of the relationship a  b, the typicality is proposed as (5) [9] .  (i,a  b)=1 -d 1 (i,a  b) / max jE d 1 (j,a  b)  ...

We specifically focus on mashups and browser-based modeling tools, a domain that increasingly targets also people without profound programming experience. ... We describe an architecture and a pattern knowledge base that are distributed over client and server and a set of client-side search algorithms for the retrieval of step-by-step recommendations. ... The former approach is based on exact matches with the object, the latter leverages on similarity search. ...

We propose a measure of user similarity based on his preference and tagging information. ... In this paper, we study a personalized recommendation model making use of the ternary relations among users, objects and tags. ... Since the typical length for recommendation list is tens, our experimental study focuses on the interval L ∈ [10, 100] . ...
