When information retrieval measures agree about the relative quality of document rankings

When information retrieval measures agree about the relative quality of document rankings

The variety of performance measures available for information retrieval systems, search engines, and network filtering agents can be confusing to both practitioners and scholars. Most discussions about these measures address their theoretical foundations and the characteristics of a measure that make it desirable for a particular application. In this work, we consider how preferences exhibited ...

Personalized Document Rankings by Incorporating Trust Information From Social Network Data into Link-Based Measures

Recently, two-layer approaches that integrate information from social networks into link-based measures on document reference networks such as the web, scientific publications or wikis gained much attention. In this paper, we extend the framework presented in [1] in order to achieve a stronger personalization of the document recommendations. Therefore, we investigate alternative approaches for ...

Beyond Document Retrieval toward Information Retrieval

RELATIVE INFORMATION FUNCTIONAL OF RELATIVE DYNAMICAL SYSTEMS

 In this paper by use of mathematical modeling of an observer [14,15] the notion of relative information functional for relative dynamical systemson compact metric spaces is presented. We extract the information function ofan ergodic dynamical system (X,T) from the relative information of T fromthe view point of observer χX, where X denotes the base space of the system.We also generalize the in...

Information Extraction: Beyond Document Retrieval

In this paper we give a synoptic view of the growth text processing technology of information extraction (IE) whose function is to extract information about a pre-specified set of entities, relations or events from natural language textsand to record this information in structured representations called templates. Here we describe the nature of the IE task, review the history of the area from i...
