Abstract

This study analyzes Spanish research on Knowledge Organization from 2002 to 2010. The first stage involved extraction of records from national and international databases that were interrogated. After getting the pertinent records, they we re normalized and processed according to the usual bibliometric procedure. The results point to a mature specialty follow ing the path of the past decade. There is a remarkable increase of male vs. female authors per publication, although the gender gap is not big. It is also evident that ther e is a remarkable internationalization in publication and that the content map of the specialty is more varied than in the previous decade.

Abstract

Julia Pettee's contribution to classification theory came about as part of her work an subject headings. Pettee (1872-1967) was for many years librarian of the Union Theological Seminary in New York and was best known for the classification system she developed for the seminary and as the author of the book Subiect Headings. She was one of the first to call attention to the fact that there was a classification system in subject headings. It was, as she put it, "completely concealed when scattered through the alphabetical sequence" (p. 98). On the other hand, she recognized that an index entry was a pointing device and existed to show users specific terms. Index terms, unlike subject headings, could be manipulated, inverted, repeated, and stated in as many words as might be desired. The subject heading, she reiterated, had in it "some idea of classification," but was designed to pull together like material and, unlike the index term, would have limited capability for supplying access by way of synonyms, catchwords, or other associative forms. It is interesting that she also thought of the subject heading in context as forming a three-dimensional system. Logically this is the case whenever one attempts to reach beyond the conventional hierarchy as described an a plane surface, and, in fact, thought out as if the classification were an a plane surface. Pettee described this dimension variously as names "reaching up and over the surface ... hands clasp[ing] in the air" from an individual term (pp. 99-100). Or, in other context, as the mapping of "the many third-dimensional criss-crossing relationships of subject headings." (p. 103) Investigations following Pettee's insight have shown the nature and the degree of the classification latent in subject headings and also in the cross-references of all indexing systems using cross-references of the associative type ("see also" or equivalent terminology). More importantly, study of this type of connection has revealed jumps in logic and meaning caused by homographs or homonyms and resulting in false connections in classification. Standardized rules for making thesauri have prevented some of the more glaring non sequiturs, but much more still needs to be done. The whole area of "related terms", for example, needs to be brought under control, especially in terms of classification mapping.

Abstract

Mobilising the information stored in documents to advance learning and social well-being provides information science with a fundamental social objective. It also presents it with a characteristic set of technical and professional problems. Until recently, information storage and retrieval systems, of which the library is one of the oldest and most important examples, have not provided a direct solutuion to the problem of providing access to needed information. Instead they have attempted to identify and provide physical access to written or printed documents that might contain information that is needed or might be useful. Perhaps creating systems to substitute what documents may be about for what documents contain is a process of realistic simplfication in the face of overwhleming technical and 'epistemological' problems. But it is speculative approaches to overcoming these problems that are the subject of this paper

Abstract

The Bünau Library catalogue (1750-56), which initially comprised 3 tomes of 7 volumes and had 16.000 authors listed in its final index, is the most systematically structured in the history of bibliography, its architecture being so analytical that it almost fulfils the librarian's dream of so organising a collection that it develops organically from within. Describes with examples of indexing the work of the Bünau Library's first director, J.M. Franke (1717-75), who began his task with the 42.000 volumes in Count Heinrich von Bülau's private collection, and later supervised their incorporation with the Brühl and Dresden Electoral Library collections

Abstract

The genesis of the Group: In 1948, as part of the post-war renewal of library services in the United Kingdom, the Royal Society organized a Conference on Scientific Information.' What, at the time, must have seemed a minute part of the grand plan, but was later to have a transforming effect on the theory of knowledge organization throughout the remainder of the century, was the setting up of a standing committee of a small group of specialists to investigate the organization and retrieval of scientific information. In 1950, the secretary of that committee, J.D. Bernal, suggested that it might be appropriate to ask a group of librarians to do a study of the problem. After a couple of years of informal discussion it was agreed, in February 1952, to form a Classification Research Group - the CRG as it has become known to subsequent generations. The Group published a brief corporate statement of its views in the Library Association Record in June 1953 and submitted a memorandum to the Library Association Research Committee in May 1955, entitled "The need for a faceted classification as the basis of all methods of information retrieval". This memorandum was published in the proceedings of what has become known as the "Dorking Conference" in 1957. Of the original fifteen members, four still belong to the Group, three of whom are in regular attendance: Eric Coates, Douglas Foskett and Jack Mills. Brian Vickery ceased attending regularly in the 1960s but has retained his interest in their doings: he was present at the 150th celebratory meeting in 1984 and played an active part in the "Dorking revisited" conference held in 1997. The stated aim of the Group was 'To review the basic principles of bibliographic classification, unhampered by allegiance to any particular published scheme' and it can truly be stated that the work of its members has had a fundamental influence on the teaching and practice of information retrieval. It is paradoxical that this collection of people has exerted such a strong theoretical sway because their aims were from the outset and remain essentially practical. This fact is sometimes overlooked in the literature on knowledge organization: there is a tendency to get carried away, and for researchers of today to concentrate so hard on what might be that they overlook what is needed, useful and practical - the entire objective of any retrieval system.

Abstract

The idea of computing with concepts as mathematicians manipulate variables in equations goes back at least as far as G. W. Leibniz (1663). Leibniz dreamed of a universal calculus, an ambiguity-free language, with which scholars could communicate ideas with mathematical precision. George Boole, in his investigation of the laws of thought, contributed to the realization of this idea by developing a calculus of classes (1847). A modern visionary who saw a practical application of Boole's work and further contributed to the idea of communicating by "computing" was Mortimer Taube (1910-1965), a member of the Library of Congress staff from 1944 to 1949 who later founded Documentation, Inc. He proposed communicating with a mechanized information store by combining concepts using the Boolean operators, AND, OR and NOT. The following selection contains one of the first presentations of a technique Taube called "coordinate indexing" and what later has come to be called "post coordinate indexing" or Boolean searching. This selection is interesting an three counts. It is interesting first of all because of its early date-1950. Though the idea of coordinate indexing had been anticipated in manual systems of the punched card sort, these systems were limited, relying for the most part an repeated application of the AND operator. To conceptualize the full power that could be achieved by Boolean search strategy in mechanized systems was an imaginative step forward. Second, the selection is interesting insofar as the idea of coordinate indexing is couched, indeed nearly hidden, in a somewhat ponderous essay an the compatibility of universal and special classifications and the merits of different methods of information organization. Ponderous though it is, the essay is worth a careful reading. The perspective it gives is enlightening, a reminder that the roots of information science reach far back into the bibliographic past. The third and perhaps most interesting aspect of this selection is that in it Taube looks beyond the technique of coordinate indexing to envisage its implications an bibliographic organization. (Now more than thirty years later we are still attempting to understand these implications.) What Taube saw was a new method of bibliographic organization, which, not ingenuously, he observed might seem almost bumptious in the face of a two thousand year history of organizing information. This "new" method was, however, being proposed elsewhere, albeit in different guise, by S. R. Ranganathan (q.v.) and his school. It was the method of organizing information using abstract categories called fields or facets. These categories, unlike those used in the great traditional classifications, were not locked in procrustean hierarchical structures, but could be freely synthesized or combined in indexing or retrieval. In short, Taube's voice was among those at midcentury supporting the move from enumerative to synthetic subject approaches. The fact that it was an American voice and one especially weIl informed about bibliography and computers is perhaps what led Jesse Shera to refer to Taube as "the Melvil Dewey ... of midtwentieth century American Librarianship," one who was able "to weld successfully conventional librarianship and the then-emerging information science."

Abstract

In 1964 Swanson published an article 'Dialogues with a catalog', in which he presented a personal prescription for what a library catalog should look like at some future date. He was in many ways remarkably visionary; some of the features he recommended have still not been implemented, although writers are again referring to their desirability. Despite its visionary qualities, Swanson's article seems to have been quite forgotten. At least, it is rarely cited. This article will trace the development of OPACs from the time they were first introduced into libraries and compare what has occured with Swanson's recommendations. It is remarkable that an article written thirty years ago could still offer a suitable framework within which to review virtually the totality of OPAC developments. The lesson that emerges most clearly from this is that the library profession should prescribe performance goals for tools and services that are not constrained by existing technologies. We must first establish requirements and seek the solutions later

Abstract

Argentine library science literature reflects a diverse interest in the subject organization of library collections. Early writings looked at the need to organize one library in particular (the National Library methodical catalog of 1893); and, therefore, the central issue was the adoption of a practical model of library organization. However, the twentieth century inaugurated the era of library studies in the strictest sense. It began an exchange of ideas about the advantages and disadvantages of decimal classification, and it resulted in the work of Carlos V. Penna by the middle of the century. This article is based on the analysis and interpretation of the primary sources, with the purpose of identifying the influences of European and American library thought on the development of the history of classification in Argentina in a period during which a national library identity began to develop.

Abstract

This article explores how linguistics has influenced information retrieval (IR) and attempts to explain the impact of linguistics through an analysis of internal developments in information science generally, and IR in particular. It notes that information science/IR has been evolving from a case science into a fully fledged, "disciplined"/disciplinary science. The article establishes correspondences between linguistics and information science/IR using the three established IR paradigms-physical, cognitive, and computational-as a frame of reference. The current relationship between information science/IR and linguistics is elucidated through discussion of some recent information science publications dealing with linguistic topics and a novel technique, "keyword collocation analysis," is introduced. Insights from interdisciplinarity research and case theory are also discussed. It is demonstrated that the three stages of interdisciplinarity, namely multidisciplinarity, interdisciplinarity (in the narrow sense), and transdisciplinarity, can be linked to different phases of the information science/IR-linguistics relationship and connected to different ways of using linguistic theory in information science and IR.

Abstract

Julia Pettee's contribution to classification theory came about as part of her work an subject headings. Pettee (1872-1967) was for many years librarian of the Union Theological Seminary in New York and was best known for the classification system she developed for the seminary and as the author of the book Subiect Headings. She was one of the first to call attention to the fact that there was a classification system in subject headings. It was, as she put it, "completely concealed when scattered through the alphabetical sequence" (p. 98). On the other hand, she recognized that an index entry was a pointing device and existed to show users specific terms. Index terms, unlike subject headings, could be manipulated, inverted, repeated, and stated in as many words as might be desired. The subject heading, she reiterated, had in it "some idea of classification," but was designed to pull together like material and, unlike the index term, would have limited capability for supplying access by way of synonyms, catchwords, or other associative forms. It is interesting that she also thought of the subject heading in context as forming a three-dimensional system. Logically this is the case whenever one attempts to reach beyond the conventional hierarchy as described an a plane surface, and, in fact, thought out as if the classification were an a plane surface. Pettee described this dimension variously as names "reaching up and over the surface ... hands clasp[ing] in the air" from an individual term (pp. 99-100). Or, in other context, as the mapping of "the many third-dimensional criss-crossing relationships of subject headings." (p. 103) Investigations following Pettee's insight have shown the nature and the degree of the classification latent in subject headings and also in the cross-references of all indexing systems using cross-references of the associative type ("see also" or equivalent terminology). More importantly, study of this type of connection has revealed jumps in logic and meaning caused by homographs or homonyms and resulting in false connections in classification. Standardized rules for making thesauri have prevented some of the more glaring non sequiturs, but much more still needs to be done. The whole area of "related terms", for example, needs to be brought under control, especially in terms of classification mapping.

Abstract

The invention of automatic indexing using a keyword-in-context approach has generally been attributed solely to Hans Peter Luhn of IBM. This article shows that credit for this invention belongs equally to Luhn and Herbert Ohlman of the System Development Corporation. It also traces the origins of title derivative automatic indexing, its development and implementation, and current status.

Abstract

In 1934, a Belgian entrepreneur named Paul Otlet sketched out plans for a worldwide network of computers-or "electric telescopes," as he called them - that would allow people anywhere in the world to search and browse through millions of books, newspapers, photographs, films and sound recordings, all linked together in what he termed a reseau mondial: a "worldwide web." Today, Otlet and his visionary proto-Internet have been all but forgotten, thanks to a series of historical misfortunes - not least of which involved the Nazis marching into Brussels and destroying most of his life's work. In the years since Otlet's death, however, the world has witnessed the emergence of a global network that has proved him right about the possibilities - and the perils - of networked information. In Cataloging the World, Alex Wright brings to light the forgotten genius of Paul Otlet, an introverted librarian who harbored a bookworm's dream to organize all the world's information. Recognizing the limitations of traditional libraries and archives, Otlet began to imagine a radically new way of organizing information, and undertook his life's great work: a universal bibliography of all the world's published knowledge that ultimately totaled more than 12 million individual entries. That effort eventually evolved into the Mundaneum, a vast "city of knowledge" that opened its doors to the public in 1921 to widespread attention. Like many ambitious dreams, however, Otlet's eventually faltered, a victim to technological constraints and political upheaval in Europe on the eve of World War II. Wright tells not just the story of a failed entrepreneur, but the story of a powerful idea - the dream of universal knowledge - that has captivated humankind since before the great Library at Alexandria. Cataloging the World explores this story through the prism of today's digital age, considering the intellectual challenge and tantalizing vision of Otlet's digital universe that in some ways seems far more sophisticated than the Web as we know it today.
The dream of universal knowledge hardly started with the digital age. From the archives of Sumeria to the Library of Alexandria, humanity has long wrestled with information overload and management of intellectual output. Revived during the Renaissance and picking up pace in the Enlightenment, the dream grew and by the late nineteenth century was embraced by a number of visionaries who felt that at long last it was within their grasp. Among them, Paul Otlet stands out. A librarian by training, he worked at expanding the potential of the catalogue card -- the world's first information chip. From there followed universal libraries and reading rooms, connecting his native Belgium to the world -- by means of vast collections of cards that brought together everything that had ever been put to paper. Recognizing that the rapid acceleration of technology was transforming the world's intellectual landscape, Otlet devoted himself to creating a universal bibliography of all published knowledge. Ultimately totaling more than 12 million individual entries, it would evolve into the Mundaneum, a vast "city of knowledge" that opened its doors to the public in 1921. By 1934, Otlet had drawn up plans for a network of "electric telescopes" that would allow people everywhere to search through books, newspapers, photographs, and recordings, all linked together in what he termed a réseau mondial: a worldwide web. It all seemed possible, almost until the moment when the Nazis marched into Brussels and carted it all away. In Cataloging the World, Alex Wright places Otlet in the long continuum of visionaries and pioneers who have dreamed of unifying the world's knowledge, from H.G. Wells and Melvil Dewey to Ted Nelson and Steve Jobs. And while history has passed Otlet by, Wright shows that his legacy persists in today's networked age, where Internet corporations like Google and Twitter play much the same role that Otlet envisioned for the Mundaneum -- as the gathering and distribution channels for the world's intellectual output. In this sense, Cataloging the World is more than just the story of a failed entrepreneur; it is an ongoing story of a powerful idea that has captivated humanity from time immemorial, and that continues to inspire many of us in today's digital age.
