文摘


The notion of information quality (IQ) has been investigated


extensively
in recent years. Much of this research has been aimed at


conceptualizing IQ and its underlying dimensions (e.g., accuracy,


completeness) and at developing instruments for measuring these


quality dimensions. However, less attention has been given to the


measurability of IQ. The objective of this study is to explore the


extent to which a set of IQ dimensions
--

accuracy, completeness,


objectivity, and representation
--

lend t
hemselves to reliable


measurement. By reliable measurement, we refer to the degree to which


independent assessors are able to agree when rating objects on these


various dimensions. Our study reveals that multiple assessors tend to


agree mor
e on certain dimensions (e.g., accuracy) while finding it


more difficult to agree on others (e.g., completeness). We argue that


differences in measurability stem from properties inherent to the


quality dimension (i.e., the availability of heuri
stics that make the


assessment more tangible) as well as on assessors' reliance on these


cues. Implications for theory and practice are discussed. [Copyright

文摘


This work identifies changes in dominant topics in library and


information science (LIS) over time, by analyzing the 3,121 doctoral


dissertations completed between 1930 and 2009 at North American


Library and Information Science programs. The authors utilize latent


Dirichlet allocation (LDA) to identify

latent topics diachronically


and to identify representative dissertations of those topics. The


findings indicate that the main topics in LIS have changed


substantially from those in the initial period (1930
-
1969) to the


present (2000
-
2009)
. However, some themes occurred in multiple


periods, representing core areas of the field: library history


occurred in the first two periods; citation analysis in the second and


third periods; and information
-
seeking behavior in the fourth and
last


period. Two topics occurred in three of the five periods: information


retrieval and information use. One of the notable changes in the


topics was the diminishing use of the word library (and related


terms). This has implications for th
e provision of doctoral education


in LIS. This work is compared to other earlier analyses and provides


validation for the use of LDA in topic analysis of a discipline.

The aim of this research is to advance both the theoretical


con
ceptualization and the empirical validation of trustworthiness in


mHealth (mobile health) information services research. Conceptually,


it extends this line of research by reframing trustworthiness as a


hierarchical, reflective construct, incorp
orating ability,


benevolence, integrity, and predictability. Empirically, it confirms


that partial least squares path modeling can be used to estimate the


parameters of a hierarchical, reflective model with moderating and


mediating effects
in a nomological network. The model shows that


trustworthiness is a second
-
order, reflective construct that has a


significant direct and indirect impact on continuance intentions in


the context of mHealth information services. It also confirms
that


consumer trust plays the key, mediating role between trustworthiness


and continuance intentions, while trustworthiness does not have any


moderating influence in the relationship between consumer trust and


continuance intentions. Overal
l, the authors conclude by discussing


conceptual contributions, methodological implications, limitations,


and future research directions of the study. [Copyright Wiley

Indexing; Information retrieval; Knowledge; Information science

AB:
文摘



A recent study in information science (IS), Lykke and Eslau (2010;


hereafter L&E), raises important issues concerning the value of


human indexing and basic theories of indexing and information


retrieval, as well as the use of quantitative and
qualitative


approaches in IS and the underlying theories of knowledge informing


the field. The present article uses L&E as the point of departure


for demonstrating in what way more social and interpretative


understandings may provide fruitf
ul improvements for research in


indexing, knowledge organization, and information retrieval. The


article is motivated by the observation that philosophical


contributions tend to be ignored in IS if they are not directly formed


as criticisms

or invitations to dialogs. It is part of the author's


ongoing publication of articles about philosophical issues in IS and


it is intended to be followed by analyzes of other examples of


contributions to core issues in IS. Although it is formul
ated as a


criticism of a specific paper, it should be seen as part of a general


discussion of the philosophical foundation of IS and as a support to


the emerging social paradigm in this field. [Copyright Wiley

The article explains why the concept of the user in Library and


Information Science (LIS) user studies and information seeking


behavior is theoretically inadequate

and it proposes a


reconceptualization of subjects, objects, and their relations


according to a model of "double mediation." Formal causation


(affordances) is suggested as a substitute for mechanistic causation.


The notion of "affective cau
sation" is introduced. The works of


several psychoanalysts and continental and Anglo
-
American philosophers


are used as tools to develop the model. [Copyright Wiley Periodicals

We describe two general approaches to creating document
-
level maps of


science. To create a local map, one defines and directly maps a sample


of data, such as all literature published in a set of information


science journals. To create a glo
bal map of a research field, one maps


"all of science" and then locates a literature sample within that full


context. We provide a deductive argument that global mapping should


create more accurate partitions of a research field than does local


mapping, followed by practical reasons why this may not be so. The


field of information science is then mapped at the document level


using both local and global methods to provide a case illustration of


the differences between the methods.

Textual coherence is used to


assess the accuracies of both maps. We find that document clusters in


the global map have significantly higher coherence than do those in


the local map, and that the global map provides unique insights into


the

field of information science that cannot be discerned from the


local map. Specifically, we show that information science and computer


science have a large interface and that computer science is the more


progressive discipline at that interface
. We also show that research


communities in temporally linked threads have a much higher coherence


than do isolated communities, and that this feature can be used to


predict which threads will persist into a subsequent year. Methods


that co
uld increase the accuracy of both local and global maps in the


future also are discussed. [Copyright Wiley Periodicals Inc.]

Automatic text analysis; Clustering; Citations

文摘


The mapping of scientific fields, based on principles established in


the seventies, has recently shown a remarkable development and


applications are now booming with progress in computing efficiency. We


examine here the convergence of two t
hematic mapping approaches,


citation
-
based and word
-
based, which rely on quite different


sociological backgrounds. A corpus in the nanoscience field was broken


down into research themes, using the same clustering technique on the


2 networks

separately. The tool for comparison is the table of


intersections of the M clusters (here M = 50) built on either side. A


classical visual exploitation of such contingency tables is based on


correspondence analysis. We investigate a rearrangem
ent of the


intersection table (block modeling), resulting in pseudo
-
map. The


interest of this representation for confronting the two breakdowns is


discussed. The amount of convergence found is, in our view, a strong


argument in favor of the

reliability of bibliometric mapping. However,


the outcomes are not convergent at the degree where they can be


substituted for each other. Differences highlight the complementarity


between approaches based on different networks. In contrast wit
h the


strong informetric posture found in recent literature, where lexical


and citation markers are considered as miscible tokens, the framework


proposed here does not mix the two elements at an early stage, in


compliance with their contras
ted logic. [Copyright Wiley Periodicals

文摘


This paper aims to review the fierc
ely discussed question of whether


the ranking of Wikipedia articles in search engines is justified by


the quality of the articles. After an overview of current research on


information quality in Wikipedia, a summary of the extended discussion



on the quality of encyclopedic entries in general is given. On this


basis, a heuristic method for evaluating Wikipedia entries is


developed and applied to Wikipedia articles that scored highly in a


search engine retrieval effectiveness test
and compared with the


relevance judgment of jurors. In all search engines tested, Wikipedia


results are unanimously judged better by the jurors than other results


on the corresponding results position. Relevance judgments often


roughly corr
espond with the results from the heuristic evaluation.


Cases in which high relevance judgments are not in accordance with the


comparatively low score from the heuristic evaluation are interpreted


as an indicator of a high degree of trust in Wik
ipedia. One of the


systemic shortcomings of Wikipedia lies in its necessarily incoherent


user model. A further tuning of the suggested criteria catalog, for


instance, the different weighing of the supplied criteria, could serve


as a starting point for a user model differentiated evaluation of


Wikipedia articles. Approved methods of quality evaluation of


reference works are applied to Wikipedia articles and integrated with


the question of search engine evaluation.

Previous studies have found that both (a) the characteristics (e.g.,

idel Green, 2004) and (b) the types


of sources (e.g., relational and nonrelational sources) (e.g., Zimmer,


Henry, Butler, 2007) influence information source selection. Different


from earlier studies that have prioritized one source attribute ov
er


the other, this research uses information need as a contingency factor


to examine information seekers' simultaneous consideration of


different attributes. An empirical test from 149 employees'


evaluations of eight information sources rev
ealed that (a) low

Search engines; Social networks; Computer supported cooperative work

AB:
文摘


Despite improv
ements in their capabilities, search engines still fail


to provide users with only relevant results. One reason is that most


search engines implement a "one size fits all" approach that ignores


personal preferences when retrieving the results o
f a user's query.


Recent studies (Smyth, 2010) have elaborated the importance of


personalizing search results and have proposed integrating recommender


system methods for enhancing results using contextual and extrinsic


information that mig
ht indicate the user's actual needs. In this


article, we review recommender system methods used for personalizing


and improving search results and examine the effect of two such


methods that are merged for this purpose. One method is based on



collaborative users' knowledge; the second integrates information from


the user's social network. We propose new methods for collaborative
-


and social
-
based search and demonstrate that each of these methods,


when separately applied, produce
more accurate search results than


does a purely keyword
-
based search engine (referred to as "standard


search engine"), where the social search engine is more accurate than


is the collaborative one. However, separately applied, these methods


do not produce a sufficient number of results (low coverage).


Nevertheless, merging these methods with those implemented by standard


search engines overcomes the low
-
coverage problem and produces


personalized results for users that display
significantly more


accurate results while also providing sufficient coverage than do


standard search engines. The improvement, however, is significant only


for topics for which the diversity of terms used for queries among


users is low. [Co

文摘


This article studies massive evidence about references made and


citations received after a 5
-
year citation window by 3.7 million


articles published in 1
998 to 2002 in 22 scientific fields. We find


that the distributions of references made and citations received share


a number of basic features across sciences. Reference distributions


are rather skewed to the right while citation distributions
are even


more highly skewed: The mean is about 20 percentage points to the


right of the median, and articles with a remarkable or an outstanding


number of citations represent about 9% of the total. Moreover, the


existence of a power law rep
resenting the upper tail of citation


distributions cannot be rejected in 17 fields whose articles represent


74.7% of the total. Contrary to the evidence in other contexts, the


value of the scale parameter is above 3.5 in 13 of the 17 cases.


Finally, power laws are typically small, but capture a considerable


proportion of the total citations received. [Copyright Wiley

In a comprehensive research project, we investigated the predictive


validity of selection decisions and reviewers' ratings at the open



access journal Atmospheric Chemistry and Physics (ACP). ACP is a


high
-
impact journal publishing papers on the Earth's atmosphere and


the underlying chemical and physical processes. Scientific journals


have to deal with the following question c
oncerning the predictive


validity: Are in fact the "best" scientific works selected from the


manuscripts submitted? In this study we examined whether selecting the


"best" manuscripts means selecting papers that after publication show


top ci
tation performance as compared to other papers in this research


area. First, we appraised the citation impact of later published


manuscripts based on the percentile citedness rank classes of the


population distribution (scaling in a specific su
bfield). Second, we


analyzed the association between the decisions (n=677 accepted or


rejected, but published elsewhere manuscripts) or ratings (reviewers'


ratings for n=315 manuscripts), respectively, and the citation impact


classes of the manuscripts. The results confirm the predictive


validity of the ACP peer review system. [Copyright Wiley Periodicals

Many countries are moving towards research policies that emphasize


excellence; consequently; they develop evaluation systems to identify


universities, research groups, and researchers that can be said to be


"excellent." Such active research

policy strategies, in which


evaluations are used to concentrate resources, are based on an


unsubstantiated assumption that researchers' track records are


indicative of their future research performance. In this study,


information on author
s' track records (previous publication volume and


previous citation rate) is used to predict the impact of their


articles. The study concludes that, to a certain degree, the impact of


scientific work can be predicted using information on how of
ten an


author's previous publications have been cited. The relationship


between past performance and the citation rate of articles is


strongest at the high end of the citation distribution. The


implications of these results are discussed in

the context of a


cumulative advantage process. [Copyright Wiley Periodicals Inc.]

Following the transition from print journals to electronic (hybrid)


journals in the past decade, usage metrics have become an interesting


complement to citation metrics. In this article we investigate the


similarities of and differe
nces between usage and citation indicators


for pharmacy and pharmacology journals and relate the results to a


previous study on oncology journals. For the comparison at journal


level we use the classical citation indicators as defined in the



Journal Citation Reports and compute the corresponding usage


indicators. At the article level we not only relate download and


citation counts to each other but also try to identify the possible


effect of citations upon subsequent downloads. U
sage data were


provided by ScienceDirect both at the journal level and, for a few


selected journals, on a paper
-
by
-
paper basis. The corresponding


citation data were retrieved from the Web of Science and Journal


Citation Reports. Our analyse
s show that electronic journals have


become generally accepted over the last decade. While the supply of


ScienceDirect pharma journals rose by 50% between 2001 and 2006, the


total number of article downloads (full
-
text articles [FTAs])


multiplied more than 5
-
fold in the same period. This also impacted the


pattern of scholarly communication (strong increase in the immediacy


index) in the past few years. Our results further reveal a close


relation between citation and downl
oad frequencies. We computed a high


correlation at the journal level when using absolute values and a


moderate to high correlation when relating usage and citation impact


factors. At the article level the rank correlation between downloads


and citations was only medium
-
sized. Differences between downloads and


citations exist in terms of obsolescence characteristics. While more


than half of the articles are downloaded in the publication year or 1


year later, the median cited half
-
life was nearly 6 years for our


journal sample. Our attempt to reveal a direct influence of citations


upon downloads proved not to be feasible. [Copyright Wiley Periodicals

This article describes the research stimulated by a fundamental shift


that is occurring in the manufacture and marketing of aero engines for


commercial and defense purposes, away from the selling of products to


the provision of services. This research was undertaken in an


aerospace company, which designs and manufactures aero engines and


also offers contracts, under which it rem
ains responsible for the


maintenance of engines. These contracts allow the company to collect


far more data about the in
-
service performance of their engines than


was previously available. This article aims at identifying what parts


of this

in
-
service information are required when components or systems


of existing engines need to be redesigned because they have not


performed as expected in service. In addition, this article aims at


understanding how designers use this in
-
service
information in a


redesign task. In an attempt to address these aims, we analyzed five


case studies involving redesign of components or systems of an


existing engine. The findings show that the in
-
service information


accessed by the designer
s mainly contains the undesired physical


actions (e.g., deterioration mechanisms, deterioration effects, etc.)


and the causal chains of these undesired physical actions. We


identified a pattern in the designers' actions regarding the use of



these causal chains. The designers have generated several solutions


that utilize these causal chains seen in the in
-
service information.


The findings provide a sound basis for developing tools and methods to


support designers in effectively sa
tisfying their in
-
service


information requirements in a redesign task. [Copyright Wiley

The explosion of disaster health information results in information


overload among response professionals. The objective of this project


was to determine the fe
asibility of applying semantic natural language


processing (NLP) technology to addressing this overload. The project


characterizes concepts and relationships commonly used in disaster


health
-
related documents on influenza pandemics, as the basi
s for


adapting an existing semantic summarizer to the domain. Methods


include human review and semantic NLP analysis of a set of relevant


documents. This is followed by a pilot test in which two information


specialists use the adapted appli
cation for a realistic


information
-
seeking task. According to the results, the ontology of


influenza epidemics management can be described via a manageable


number of semantic relationships that involve concepts from a limited


number of sema
ntic types. Test users demonstrate several ways to


engage with the application to obtain useful information. This


suggests that existing semantic NLP algorithms can be adapted to


support information summarization and visualization in influenza


epidemics and other disaster health areas. However, additional


research is needed in the areas of terminology development (as many


relevant relationships and terms are not part of existing standardized


vocabularies), NLP, and user interface

design. [Copyright Wiley

文摘


A huge number of informal messages are posted every day in social


network sites, blogs, and discussion forums. Emotions seem to be


frequently important in these texts for expressing friendship, showing


social support o
r as part of online arguments. Algorithms to identify


sentiment and sentiment strength are needed to help understand the


role of emotion in this informal communication and also to identity


inappropriate or anomalous affective utterances, potent
ially


associated with threatening behavior to the self or others.


Nevertheless, existing sentiment detection algorithms tend to be


commercially oriented, designed to identify opinions about products


rather than user behaviors. This article
partly fills this gap with a


new algorithm, SentiStrength, to extract sentiment strength from


informal English text, using new methods to exploit the de facto


grammars and spelling styles of cyberspace. Applied to MySpace


comments and with a lookup table of term sentiment strengths optimized


by machine learning, SentiStrength is able to predict positive emotion


with 60.6% accuracy and negative emotion with 72.8% accuracy, both


based upon strength scales of 1
-
5. The former, but not the latter, is


better than baseline and a wide range of general machine learning


approaches. [Copyright Wiley Periodicals Inc.]

Navigating; Online information retrieval; Personal files

AB:
文摘


Folder navigation is the main way that personal computer users


retrieve their own files. People dedicate considerable time to


creating systematic structures to facilitate such
retrieval. Despite


the prevalence of both manual organization and navigation, there is


very little systematic data about how people actually carry out


navigation, or about the relation between organization structure and


retrieval parameters
. The aims of our research were therefore to study


users' folder structure, personal file navigation, and the relations


between them. We asked 296 participants to retrieve 1,131 of their


active files and analyzed each of the 5,035 navigation steps in these


retrievals. Folder structures were found to be shallow (files were


retrieved from mean depth of 2.86 folders), with small folders (a mean


of 11.82 files per folder) conta
ining many subfolders (M=10.64).


Navigation was largely successful and efficient with participants


successfully accessing 94% of their files and taking 14.76 seconds to


do this on average. Retrieval time and success depended on folder size


and depth. We therefore found the users' decision to avoid both deep


structure and large folders to be adaptive. Finally, we used a


predictive model to formulate the effect of folder depth and folder


size on retrieval time, and suggested an opt
imization point in this


tradeoff. [Copyright Wiley Periodicals Inc.]

We studied the effectiveness of a new
class of context
-
dependent term


weights for information retrieval. Unlike the traditional term


frequency
-
inverse document frequency (TF
-
IDF), the new weighting of a


term t in a document d depends not only on the occurrence statistics


of t a
lone but also on the terms found within a text window (or


"document
-
context") centered on t. We introduce a Boost and


Discount (B&D) procedure which utilizes partial relevance


information to compute the context
-
dependent term weights of query


terms according to a logistic regression model. We investigate the


effectiveness of the new term weights compared with the


context
-
independent BM25 weights in the setting of relevance feedback.


We performed experiments with title queries of

the TREC
-
6,
-
7,
-
8, and


2005 collections, comparing the residual Mean Average Precision (MAP)


measures obtained using B&D term weights and those obtained by a


baseline using BM25 weights. Given either 10 or 20 relevance judgments


of the to
p retrieved documents, using the new term weights yields


improvement over the baseline for all collections tested. The MAP


obtained with the new weights has relative improvement over the


baseline by 3.3 to 15.2%, with statistical significance a
t the 95%


confidence level across all four collections. [Copyright Wiley

Ranking; Term frequency; Web pages

AB:
文摘


In this work, we investigate the probl
em of using the block structure


of Web pages to improve ranking results. Starting with basic


intuitions provided by the concepts of term frequency (TF) and inverse


document frequency (IDF), we propose nine block
-
weight functions to


distinguish the impact of term occurrences inside page blocks, instead


of inside whole pages. These are then used to compute a modified BM25


ranking function. Using four distinct Web collections, we ran


extensive experiments to compare our
block
-
weight ranking formulas


with two other baselines: (a) a BM25 ranking applied to full pages,


and (b) a BM25 ranking that takes into account best blocks. Our


methods suggest that our block
-
weighting ranking method is superior to


all bas
elines across all collections we used and that average gain in


precision figures from 5 to 20% are generated. [Copyright Wiley

文摘


Although technology can often correct spelling errors, the complex


tasks of information searching and retrieval in an online public


ac
cess catalog (OPAC) are made more difficult by these errors in


users' input and bibliographic records. This study examines the search


behaviors of 38 university students, divided into groups with either


easy
-
to
-
spell or difficult
-
to
-
spell searc
h terms, who were asked to


find items in the OPAC with these search terms. Search behaviors and


strategy use in the OPAC and on the World Wide Web (WWW) were


examined. In general, students used familiar Web resources to check


their spelling or discover more about the assigned topic. Students


with difficult
-
to
-
spell search terms checked spelling more often,


changed search strategies to look for the general topic and had fewer


successful searches. Students unable
to find the correct spelling of a


search term were unable to complete their search. Students tended to


search the OPAC as they would search a search engine, with few search


terms or complex search strategies. The results of this study have


implications for spell checking, user
-
focused OPAC design, and


cataloging. Students' search behaviors are discussed by expanding

文摘


To enable and guide effective metadata creation it is essential to


understand the structure and patterns of the a
ctivities of the


community around the photographs, resources used, and scale and


quality of the socially created metadata relative to the metadata and


knowledge already encoded in existing knowledge organization systems.


This article presen
ts an analysis of Flickr member discussions around


the photographs of the Library of Congress photostream in Flickr. The


article also reports on an analysis of the intrinsic and relational


quality of the photostream tags relative to two knowledge organization


systems: the Thesaurus for Graphic Materials (TGM) and the Library of


Congress Subject Headings (LCSH). Thirty seven percent of the original


tag set and 15.3% of the pre
processed set (after the removal of tags


with fewer than three characters and URLs) were invalid or misspelled


terms. Nouns, named entity terms, and complex terms constituted


approximately 77% of the preprocessed set. More than a half of the



photostream tags were not found in the TGM and LCSH, and more than a


quarter of those terms were regular nouns and noun phrases. This


suggests that these terms could be complimentary to more traditional


methods of indexing using controlled vo
cabularies. [Copyright Wiley

revealed that topic familiarity was associated with other factors that
