Social search is a behavior of retrieving and searching on a social searching engine that mainly searches user-generated content such as news, videos and images related search queries on social media like Facebook, LinkedIn, Twitter, Instagram and Flickr. It is an enhanced version of web search that combines traditional algorithms. The idea behind social search is that instead of ranking search results purely based on semantic relevance between a query and the results, a social search system also takes into account social relationships between the results and the searcher. The social relationships could be in various forms. For example, in LinkedIn people search engine, the social relationships include social connections between searcher and each result, whether or not they are in the same industries, work for the same companies, belong the same social groups, and go the same schools, etc.

Friend clustering-based social search evaluation method for LBSN

The invention discloses a friend clustering-based social search evaluation method for an LBSN. Multi-dimensional characteristics such as location-based information, contact person information and the like are extracted from a Foursquare real data set; a friend clustering-based KNN search algorithm is proposed; a reverse index-based search engine is designed; and in combination with factors such as a distance and the like, a search result is more accurate and the search speed is increased. For enabling the search result to be more accurate, firstly, friends are clustered on the basis of researching user friends. The LBSN belongs to a heterogeneous network, and the data set is relatively sparse, so that data can be denser by clustering; singular points are eliminated, so that adverse influence caused by data sparsity is reduced; secondly, in design of the search algorithm, on the basis of considering conventional social contact influence, two indexes including professional relevance and distance are added, namely, a comprehensive search score, a social contact score and a distance score are considered; and finally, the three indexes are integrated, a linear planning model is built and trained, and the search result is obtained, so that a user is satisfied with the search result.
