Investigations in Unsupervised Back-of-the-Book Indexing

چکیده
This paper describes our experiments with unsupervised methods for back-of-the-book index construction. Through comparative evaluations performed on a gold standard data set of 29 books and their corresponding indexes, we draw conclusions as to what are the most accurate unsupervised methods for automatic index construction. We show that if the right sequence of methods and heuristics is used, the performance of an unsupervised back-of-the-book index construction system can be raised with up to 250% relative increase in F-measure as compared to the performance of a system based on the traditional tf*idf weighting scheme.

متن کاملSyntactic Approaches to Automatic Book Indexing
Automatic book indexing systems are based on the generation of phrase structures capable of reflecting text content. • Some approaches are given for the automatic construction of back-of-book indexes using a syntactic analysis of the available texts, followed by the identification of nominal constructions, the assignment of importance weights to the term phrases, and the choice of phrases as in...

The paper reports research on automatic back-of-the-book indexing. It presents a methodology which brings together knowledge from different disciplines. It is inspired by human indexing methodology and the results are more similar to manually-crafted indexes than those produced by previous automatic approaches. Issues of evaluation and applications are addressed. Résumé : Cette communication pr...
متن کاملLinguistically Motivated Features for Enhanced Back-of-the-Book Indexing
In this paper we present a supervised method for back-of-the-book index construction. We introduce a novel set of features that goes beyond the typical frequency-based analysis, including features based on discourse comprehension, syntactic patterns, and information drawn from an online encyclopedia. In experiments carried out on a book collection, the method was found to lead to an improvement...
