Options for Query Revision When Interacting with Case Retrieval Systems

چکیده
This paper is concerned with using similarity for case retrieval, especially in interactive case retrieval systems (ICRSs). We deene and exemplify similarity metrics, which are a generalisation of similarity measures, having any partial order as their result type. Within this new similarity metric setting, we deene the notion of thèbest' cases in case retrieval. We then show the variety of ways in which users can proceed through an interaction with an ICRS to widen, narrow or otherwise change the set of retrieved`best' cases. We show that using similarity metrics rather than similarity measures increases the variety of interaction options open to users.

متن کاملPrivate Key based query on encrypted data
Nowadays, users of information systems have inclination to use a central server to decrease data transferring and maintenance costs. Since such a system is not so trustworthy, users' data usually upkeeps encrypted. However, encryption is not a nostrum for security problems and cannot guarantee the data security. In other words, there are some techniques that can endanger security of encrypted d...
