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

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.

文摘
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

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.]

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.,

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

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

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

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

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

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

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
