We study the problem of imposing conversational goals/keywords on open-domain agents, where agent is required to lead conversation a target keyword smoothly and fast. Solving this enables application agents in many real-world scenarios, e.g., recommendation psychotherapy. The dominant paradigm for tackling 1) train next-turn classifier, 2) keyword-augmented response retrieval model. However, ex...

Abstract Multi-keyword ranked searchable encryption (MRSE) supports multi-keyword contained in one query and returns the top-k search results related to keyword set. It realized effective on encrypted data. Most previous works about MRSE can only make complete rank server-side. However, with more practice, users may not be able express some keywords completely when searching. Server-side rankin...

Searchable encryption has many applications including email systems and storage systems. The usefulness of searchable encryption derives from its support of keyword-testability. Keyword-testability means that a receiver of a ciphertext can test whether the ciphertext contains a specific keyword. Recently, Bellare et al. suggested an efficientlysearchable encryption scheme with keyword-recoverab...

Increasing data on web has resulted in increasing challenge for keyword query routing. Top k routing is an approach used for keyword query search. Keyword query routing work efficiently for one or two keyword but its efficiency drastically reduces while handling multiple keywords. Our approach is to increase the efficiency even for multiple keyword querying. We are going to follow keyword-eleme...
