RSkNN: kNN Search on Road Networks by Incorporating Social Influence

Abstract

RSkNN: kNN Search on Road Networks by Incorporating Social Influence management report in data mining.Although kNN search on a road network G(r), i.e., finding k nearest objects to a query user q on G(r), has been extensively studied, existing works neglected the fact that the q’s social information can play an important role in this kNN query. Many real-world applications, such as location-based social networking services, require such a query. In this paper, we study a new problem: kNN search on road networks by incorporating social influence (RSkNN). Specifically, the state-of-the-art Independent Cascade (IC) model in social network is applied to define social influence.

One critical challenge of the problem is to speed up the computation of the social influence over large road and social networks. To address this challenge, we propose three efficient index-based search algorithms, i.e., road network-based (RN-based), social network-based (SN-based), and hybrid indexing algorithms. In the RN-based algorithm, we employ a filtering-and-verification framework for tackling the hard problem of computing social influence. In the SN-based algorithm, we embed social cuts into the index, so that we speed up the query. In the hybrid algorithm, we propose an index, summarizing the road and social networks, based on which we can obtain query answers efficiently. Finally, we use real road and social network data to empirically verify the efficiency and efficacy of our solutions.

The existing system incorporates road network and social network. Independent Cascade (IC) model in social network is applied to define social influence. One of the challenge was to speed up the computation of the social influence over large road and social networks. To address this challenge, three efficient index-based search algorithms was proposed, i.e. road network-based (RN-based), social network-based (SN-based) and hybrid indexing algorithms. In the RN-based algorithm, employs a filtering-and-verification framework for dealing with the hard problem of computing social influence. SN-based algorithm, embed social cuts into the index, so to speed up the query. In the hybrid algorithm, index was proposed, summarizing the road and social networks, based on which query answers can be obtained efficiently. In proposed system recommendation is given based on the reviews of trusted users.

INTRODUCTION

With the ever-growing quality of mobile devices (e.g., smartphones), location-based service (LBS) systems (e.g., Google Maps for Mobile) are wide deployed and accepted by mobile users. The k-nearest neighbor (kNN) search on road networks could be a basic drawback in LBS. Given a question location and a group of static objects (e.g., restaurant) on the road network, the kNN search drawback finds k nearest objects to the question location. Alone with the favored usage of LBS, the past few years have witnessed an enormous boom in location-based social networking services like Foursquare, Yelp, Loopt, Geomium and Facebook Places. All told these services, social network users are usually related to some locations (e.g., home/office addresses and visiting places).

Such location info, bridging the gap between the physical world and also the virtual world of social networks, presents new opportunities for the kNN search on road networks. The said example motivates U.S. to think about the social influence to a user once process the kNN search on road networks. Specifically, alphabetic a question user q would really like not solely retrieving k geographically nearest objects , however get an outsized social influence from q’s friends UN agency are to . Therefore, during this paper, we have a tendency to study a completely unique query: kNN search on a road-social network (RSkNN), and propose economical question process algorithms. Specifically, given Gs, Gr and q, the RSkNN search finds k nearest objects (Aq = ) to question q’s location on Gr, specified the social influence SI(or) to Q through q’s friends, UN agency are to or, is a minimum of a threshold.

RELATED WORK

In this paper a kNN search on road networks by incorporating social influence (RSkNN). Independent Cascade(IC) model in social network is applied to dene social influence. One critical challenge of the problem is to speed up the computation of the social influence over large road and social networks. In Supercomputing. Under certain reasonable assumptions that even if no revetment is used in the un-coarsening phase, a good bisection of the coarser graph is worse than a good bisection of then graph by at most a small factor. Models for the processes by which ideas and influence propagate through a social network have been studied  a number of domains, Including the diffusion of medical and technological innovations, the sudden and widespread adoption of various strategies in game-theoretic settings, and the effects of word of mouth in the promotion of new products.

In this paper, The System can provide novel ranking methods that are different from the ICM, typical methods of social network analysis, and Page Rank method. Moreover, It experimentally demonstrate that when the propagation probabilities through links are small, they can give good approximations to the ICM for sets of influential nodes. A novel hybrid genetic algorithm (GA) that globally optimal partition of a given data into a specie number of clusters. To circumvent these expensive operations, it hybridize GA with a classical gradient descent algorithm used in clustering, viz. K-means algorithm. Hence, the name genetic K-means algorithm (GKA).The location-aware influence maximization problem. One big challenge in location-aware influence maximization is to develop an efficient scheme that offers wide influence spread. To address this challenge, it propose two greedy algorithms with 1 1/e approximation ratio. To meet the instant speed requirement, it propose two efficient algorithms with (1 1/e) approximation ratio for any (0,1).

In this paper User’s interests are modeled by check-inactions. Here a Spatial-aware Interest Group (SIG) query that retrieves a user group of size k where each user is interested in the query keywords and they are close to each other in the Euclidean space. It prove that the SIG query problem is NP-complete. Approximation algorithms have developed in response to the impossibility of solving a great variety of important optimization problems. Too frequently, when attempting to get a solution for a problem, one is confronted with the fact that the problem is NP-hard. While this is a significant theoretical step, it hardly qualifies as a cheering piece of news. Three simple efficient algorithms with good probabilistic behavior two algorithms with run times of O(n(log n)2) which almost certainly nd directed (undirected)

Hamiltonian circuits in random graph so fat least cn log n edges, and an algorithm with a runtime of O(n log n) which almost certainly a perfect matching in a random graph of at least cn log n edges. In this paper the systematic work on GeoSN query processing. Proposed a general frame work that offers exile data management and algorithmic design. Architecture segregates the social, geographical and query processing modules. Each GeoSN query is processed via a transparent combination of primitive queries issued to the social and geographical modules. Design a heuristic algorithm that is easily scalable to millions of nodes and edges in our experiments . The study influence maximization in the linear threshold model, one of the important models formalizing the behavior of influence propagation in social networks. It show that computing exact influence in general networks in the linear threshold model is P-hard, which closes an open problem left in the seminal work on influence maximization.
