title = "Cross-modal search on social networking systems by exploring Wikipedia concepts",
abstract = "The increasing popularity of social networking systems (SNSs) has created large quantities of data from multiple modalities such as text and image. Retrieval of data, however, is constrained to a specific modality. Moreover, text on SNSs is usually short and noisy, and remains active for a (short) period. Such characteristics, conflicting with settings of traditional text search techniques, render them ineffective in SNSs. To alleviate these problems and bridge the gap between searches over different modalities, we propose a new algorithm that supports cross-modal search about social documents as text and images on SNSs. By exploiting Wikipedia concepts, text and images are transformed into a set of common concepts, based on which searches are conducted. A new ranking algorithm is designed to rank social documents based on their informativeness and semantic relevance to a query. We evaluate our ranking algorithm on both Twitter and Facebook datasets. The results confirm the effectiveness of our approach.",
