Picture retrieval clustering method facing to Web2.0 label picture shared space
2009
The invention discloses a retrieval result clustering method facing to a Web2.0 label picture shared space, which comprises the following steps: excavating a vocabulary relationship and an associated relationship between labels; obtaining an expanded querying label set by a query label according to the vocabulary relationship between the labels; obtaining a candidate image set relevant to query by the expanded query label set; selecting front K most relevant labels according to the relevance measurement of the labels in the query label set and the candidate image set; automatically dividing the K labels into an optimal clustering result according to the association between the K labels by a clustering algorithm based on a picture division from top to bottom; and correspondingly clustering the candidate image set according to clustering labels. Aiming at the problem of inconformity of label expression, the effective query expansion is realized, and the image clustering method based on most relevant label set clustering solves the problem of diversity of label semanteme. Compared with a traditional method, the invention leads a user to rapidly and effectively retrieve and browse a picture in the Web2.0 label picture shared space.
