Alamelukiruthika MCA.,M.Phil, Asst.Prof.in Departmant of Computer Application, Bon Secours College for Women, Thanjavur, Tamil Nadu, India Anthropology has been called “the most humane of the sciences and the most scientific of the humanities”. The Wide range of approaches that span in this field are Science (hypothesis, observation, and testing) and Humanities (more subjective, based on feeling)The word anthropology itself tells the basic story--from the Greek anthropos ("human") and logia ("study“) .Anthropology is The study of humanity, including our prehistoric origins and contemporary human diversity The goals of Anthropology are to study diversity and preserve diversity,study commonalities in all humanity,look at our own culture more objectively, like an outsider and to apply this knowledge in an attempt to alleviate human challenges. In this paper we would discuss few data mining techniques used for social network analysis which forms a part of Liguistic or social anthropology. Social anthropology deals with the study of communication, mainly (but not exclusively) among humans.Sociolinguistics is a subfield which deals with the study of communication in social life (analysis of discourse) and the variations of communication in different cultural contexts The emergence of worldwide web has led to social Interaction,Knowledge Exchange,Knowledge Discovery Data mining techniques can be used for building descriptive and predictive models of social interactions with a very fine granularity and with practically no reporting bias In a social network analysis datamining can be used for Community Extraction,Link Prediction, Cascading Behavior,Identifying Prominent Actors and Experts in Social Networks,Search in Social Networks,Trust in Social Networks,Characterization of Social Networks and Anonymity in Social Networks I. COMMUNITY EXTRACTION Inherent to social networks are communities, which are groups of individuals connected to each other in some way . Communities play a vital role in understanding the creation, representation, and transfer of knowledge among people, and are an essential building block of all social networks. Discovering communities of users in a social network is Possible to use popular link analysis techniques like HITS algorithm and Graph Clustering techniques.

LINK PREDICTION Given a snapshot of a social network, can we infer which new interactions among its members are likely to occur in the near future? We formalize this question as the link prediction problem, and develop approaches to link prediction based on measures for analyzing the “proximity” of nodes in a network. We can also find the following , – Given a social network at time ti predict the social link between actors at time ti+1 – Given a social network with an incomplete set of social links between a complete set of actors, predict the unobserved social links – Given information about actors, predict the social link between them (this is quite similar to social network extraction Classical approach for link prediction is to fit the social network on a model and then use it for link prediction.Latent Space model , Dynamic Latent Space model and p* model can be used. III. CASCADING BEHAVIOUR Theoretical models suggest that social networks influence the evolution of cooperation, but to date there have been few experimental studies. Observational data suggest that a wide variety of behaviors may spread in human social networks, but subjects in such studies can choose to befriend people with similar behaviors, posing difficulty for causal inference. Bandwagon Dynamics and Granovetter's threshold model can describe cascading behaviours Link mining Link mining involves data Mining techniques that take into account the links between objects and entities while building predictive or descriptive models. Link based object ranking, Group Detection, Entity Resolution, Link Prediction are some of the techniques used Its applications are Hyperlink Mining, Relational Learning, Inductive Logic Programming,and Graph Mining Kleinberg’s Hubs and Authorities techniques can be used for link mining. Identifying Prominent Actors in a Social Network A common approach is to compute scores/rankings over the set (or a subset) of actors in the social network which indicate degree of importance/expertise/influence – E.g. Pagerank, HITS, centrality measures.The Centrality measures that exist in the social science domain for measuring importance of actors in a social network are Degree Centrality ,Closeness Centrality, Betweenness Centrality © 2015, IJARCSSE All Rights Reserved Page | 7 Alamelukiruthika, International Journal of Advanced Research in Computer Science and Software Engg. 5 (3), March- 2015, pp. 6-8 IV. IDENTIFYING EXPERTS IN A SOCIAL NETWORK Link analysis can be used for for expert identification the other mehods are Steyvers et al „s Bayesian model to assign topic distributions to users which can be used for ranking them with reference to the topics and Harada et al ,use a search engine to retrieve top k pages for a particular topic query and then extract the users present in them Search in Social Networks The search in social networks can include querying for information in a social network,query routing in a network.A user can send out queries to neighbours and if the neighbor knows the answer then he/she replies else forward it to their neighbors. Thus a query propagates through a networkand to develop schemes for efficient routing through a network. According to Watts-Dodds-Newman's Model individuals in a social network are marked by distinguishing characteristics,groups of individuals can be grouped under groups of groups,group membership is the primary basis for social interaction, Individuals hierarchically cluster the social world in multiple ways based on different attributes,Perceived similarity between individuals determine 'social distance' between them. © 2015, IJARCSSE All Rights Reserved Page | 8
