Previous work on partial retrieval of structured document has limited applications due to the requirement of structured queries and restriction

We describe a pilot test of the proposed test collection construction methodology performed on a document collection of Shakespeare plays. In our analysis, we examine the effect of query complexity and type on overall query difficu

BEPs are intended to support users’ natural information seeking behaviour by providing optimal starting points for browsing to relevant objects. Analysis of the resul

In this work we present research carried out at ITC-irst on named entity recognition in Italian broadcast news. In particular, an original statistical named entity tagger is described which can be trained wi

We look at some of their statistical properties, and determine for each representation the optimal choice of classification parameters and the effect of Term Selection..Phrases are represented by an abstraction called Head/Modifier pairs.

We report on our experiments on stemming for German, where an additional issue is the handling of compounds, which are formed by concatenating several words. Rarely do studies on ste

In the evaluation procedure, we test eight different preprocessing schemes for the data, and come to the conclusion that lemmatization combined with breaking

Second, by applying a term-proximity scoring heuristic to the top documents returned by a keyword-based system, our aim is to enhance retrieval performance. O
