    Abstract
    In this article we present FLUX-CiM, a novel method for extracting components (e.g., author names, article titles, venues, page numbers) from bibliographic citations. Our method does not rely on patterns encoding specific delimiters used in a particular citation style. This feature yields a high degree of automation and flexibility, and allows FLUX-CiM to extract from citations in any given format. Differently from previous methods that are based on models learned from user-driven training, our method relies on a knowledge base automatically constructed from an existing set of sample metadata records from a given field (e.g., computer science, health sciences, social sciences, etc.). These records are usually available on the Web or other public data repositories. To demonstrate the effectiveness and applicability of our proposed method, we present a series of experiments in which we apply it to extract bibliographic data from citations in articles of different fields. Results of these experiments exhibit precision and recall levels above 94% for all fields, and perfect extraction for the large majority of citations tested. In addition, in a comparison against a state-of-the-art information-extraction method, ours produced superior results without the training phase required by that method. Finally, we present a strategy for using bibliographic data resulting from the extraction process with FLUX-CiM to automatically update and expand the knowledge base of a given domain. We show that this strategy can be used to achieve good extraction results even if only a very small initial sample of bibliographic records is available for building the knowledge base.

    Abstract
    IFLA's Functional Requirements for Bibliographic Records (FRBR) lay the foundation for a new generation of cataloging systems that recognize the difference between a particular work (e.g., Moby Dick), diverse expressions of that work (e.g., translations into German, Japanese and other languages), different versions of the same basic text (e.g., the Modern Library Classics vs. Penguin editions), and particular items (a copy of Moby Dick on the shelf). Much work has gone into finding ways to infer FRBR relationships between existing catalog records and modifying catalog interfaces to display those relationships. Relatively little work, however, has gone into exploring the creation of catalog records that are inherently based on the FRBR hierarchy of works, expressions, manifestations, and items. The Perseus Digital Library has created a new catalog that implements such a system for a small collection that includes many works with multiple versions. We have used this catalog to explore some of the implications of hierarchical catalog records for searching and browsing. Current online library catalog interfaces present many problems for searching. One commonly cited failure is the inability to find and collocate all versions of a distinct intellectual work that exist in a collection and the inability to take into account known variations in titles and personal names (Yee 2005). The IFLA Functional Requirements for Bibliographic Records (FRBR) attempts to address some of these failings by introducing the concept of multiple interrelated bibliographic entities (IFLA 1998). In particular, relationships between abstract intellectual works and the various published instances of those works are divided into a four-level hierarchy of works (such as the Aeneid), expressions (Robert Fitzgerald's translation of the Aeneid), manifestations (a particular paperback edition of Robert Fitzgerald's translation of the Aeneid), and items (my copy of a particular paperback edition of Robert Fitzgerald's translation of the Aeneid). In this formulation, each level in the hierarchy "inherits" information from the preceding level. Much of the work on FRBRized catalogs so far has focused on organizing existing records that describe individual physical books. Relatively little work has gone into rethinking what information should be in catalog records, or how the records should relate to each other. It is clear, however, that a more "native" FRBR catalog would include separate records for works, expressions, manifestations, and items. In this way, all information about a work would be centralized in one record. Records for subsequent expressions of that work would add only the information specific to each expression: Samuel Butler's translation of the Iliad does not need to repeat the fact that the work was written by Homer. This approach has certain inherent advantages for collections with many versions of the same works: new publications can be cataloged more quickly, and records can be stored and updated more efficiently.
