Employing the resolution power of search keys
Search key resolution power is analyzed in the context of a request, i.e., among the set of search keys for the request. Methods of characterizing the resolution power of keys automatically are studied and the effects search keys of varying resolution power have on retrieval effectiveness are analyzed. It is shown that it often is possible to identify the best key of a query while the discrimin...
متن کاملStatistical linkage keys: How effective are they?
Existing measures of statistical linkage keys (SLKs) have usually focussed on how well a key represents the source population and on the extent of duplication ie multiple keys for one individual as well as multiple individuals sharing the same key. We really need to know whether the analysis of data linked by deterministic matching of SLKs leads to signifi cantly different conclusions than woul...
متن کاملSpecifications as Search Keys for Software Libraries
Searching through a large repository of objects can be a tedious activity if a user cannot easily identify the object of interest. If the object is a file stored in a campus-wide distributed file system, the user might need to know some part of its name, e.g., a partial pathname, and possibly its location, e.g., the host name of the file server. If the object is a database record, the user migh...
متن کاملInducing Search Keys for Name Filtering
This paper describes ETK (Ensemble of Transformation based Keys) a new algorithm for inducing search keys for name filtering. ETK has the low computational cost and ability to filter by phonetic similarity characteristic of phonetic keys but is adaptable to alternative similarity models. A preliminary empirical evaluation suggests that ETK may be well-suited for phonetic filtering applications ...
متن کاملInformation Behavior of Elites in the Search of Knowledge Requirement
Abstract: Information behavior is one of the important research fields in the knowledge management. It could be considered as an effective factor in design, development and evaluation of data mining applications. This paper introduces an approach called elite information behavior in response to educational and research evolutions. This research is quantitative and tries to investigate the diffe...
