User studies aim to understand how users interact with and utilize information sources. There are two main types of user studies: usage studies which examine what, why, and how much is used, and behavior studies which examine how and why something is used. Methodologically, user studies employ various qualitative and quantitative methods like interviews, surveys, observations, and log/keystroke analysis to understand user behaviors and inform systems design.

The real challenge in the modern world is not producing information or storing information,
but apt and proper use of information by people. Since volume of information is growing in leaps
and bounds, the information needs of users are becoming more and more diverse and complex. In
this changing context information providers are facing a lot of challenges to capture, process, store
and disseminate the available information for actual users. The user studies provide a clear
understanding of the actual information needs of the user in order to readjust the existing
information systems or chose new ones. Various models of information needs and informationseeking behaviour have been discussed. Each modelrepresents a different but an overlapping or
similar approach to information seeking behavior of users. In order to satisfy the information need,the user actively undergoes the information seeking processes. Some factors like physiological,emotional, learning and demographic, etc. also deeply influence information seeking behaviour i.e.
some people have to face some obstacles. These barriers may be economic, social, environmental,
time related or geographical.Effectiveness of a professional depends upon dissemination and use of right information at
right time. Information and communication technologies have changed the way in which thelibraries provide their services. Users study provide deeperunderstanding of access to their
collections and services .The need and behavior of their users and satisfaction ratio of users are
new assessment techniques of libraries. Therefore an effort has been made to how determineinformation need and information seeking behavior of users.
The present paper deals with the concept, need, types of
information literacy. Further it explores about the information literacy models, standards/frameworks, popular information literacy programmes and groups, and Information Literacy Programmes held in the Scientific Institutes of Kolkata.

Αρχειακά Μεταδεδομένα: Πρότυπα και Διαχείριση στον Παγκόσμιο ΙστόGiannis Tsakonas
Από τη δεκαετία του 1970 μέχρι σήμερα το Διεθνές Συμβούλιο Αρχείων δημιουργεί και παρέχει στην κοινότητα των Αρχείων και των Αρχειονόμων μια σειρά από πρότυπα για την ανάπτυξη αρχειακών βοηθημάτων έρευνας και συναφών καταλόγων και ευρετηρίων. Στόχος των προτύπων είναι η κοινή αντίληψη, προσέγγιση και ομοιομορφία στη δημιουργία καταλόγων, καθιερωμένων εγγραφών και στη θεματική περιγραφή των αρχείων, της δομής και του περιεχομένου τους.
Ο Παγκόσμιος ιστός έχει γίνει ένα από τα σημαντικότερα μέσα διακίνησης πληροφορίας και η εκρηκτική ανάπτυξη των αντίστοιχων τεχνολογιών ανάπτυξης εφαρμογών στο περιβάλλον του έχει οδηγήσει στην αξιοποίησή του από διάφορες κοινότητες. Σε αυτό το πλαίσιο οι Αρχειονόμοι καλούνται να κωδικοποιήσουν τα μεταδεδομένα τους και να τα καταστήσουν ικανά να διαλειτουργήσουν σε ένα παγκόσμιο περιβάλλον διαχείρισης πληροφορίας και γνώσης, όπου όλες οι επιστημονικές κοινότητες συνυπάρχουν.
Στόχος του σεμιναρίου είναι να παρουσιάσει (α) βασικά πρότυπα διαχείρισης αρχειακής πληροφορίας και (β) το τεχνολογικό υπόβαθρο το οποίο καθορίζει τους τρόπους με τους οποίους είναι δυνατή η ανταλλαγή και η διαλειτουργικότητα - διασύνδεση της αρχειακής πληροφορίας με την πληροφορία που παράγουν άλλοι οργανισμοί και κοινότητες με τις οποίες οι αρχειακές υπηρεσίες έχουν άμεση σχέση.
Το σεμινάριο απευθύνεται σε εργαζόμενους σε δημόσιους και ιδιωτικούς αρχειακούς φορείς, φοιτητές και πτυχιούχους αρχειονόμους, βιβλιοθηκονόμους και πτυχιούχους Πανεπιστημίων και ΤΕΙ με παρεμφερή επαγγελματικά και επιστημονικά ενδιαφέροντα.
Το σεμινάριο εντάσσεται στις δραστηριότητες της Ομάδας Βάσεων Δεδομένων και Πληροφοριακών Συστημάτων του Εργαστηρίου Ψηφιακών Βιβλιοθηκών και Ηλεκτρονικής Δημοσίευσης του Τμήματος Αρχειονομίας, Βιβλιοθηκονομίας και Μουσειολογίας του Ιονίου Πανεπιστημίου, διοργανώνεται στο πλαίσιο του 21st International Conference on Theory and Practice of Digital Libraries και θα διεξαχθεί στο ξενοδοχείο Grand Hotel Palace, Μοναστηρίου 305, Θεσσαλονίκη, την Τρίτη 19 Σεπτεμβρίου 2017 και ώρες 14.00 – 17.00.
The “Nomenclature of Multidimensionality” in the Digital Libraries Evaluation...Giannis Tsakonas
Digital libraries evaluation is characterised as an interdisciplinary and multidisciplinary domain posing a set of challenges to the research communities that intend to utilise and assess criteria, methods and tools. The amount of scientific production, which is published on the field, hinders and disorientates the researchers who are interested in the domain. The researchers need guidance in order to exploit the considerable amount of data and the diversity of methods effectively as well as to identify new research goals and develop their plans for future works. This paper proposes a methodological pathway to investigate the core topics of the digital library evaluation domain, author communities, their relationships, as well as the researchers who significantly contribute to major topics. The proposed methodology exploits topic modelling algorithms and network analysis on a corpus consisting of the digital library evaluation papers presented in JCDL,ECDL/TDPL and ICADL conferences in the period 2001–2013.

Increasing traceability of physical library items through Koha: the case of S...Giannis Tsakonas
Presentation in KohaCon2016, the major event of Koha community, on May 31, 2016. The Library & Information Center, University of Patras, Greece has developed the SELIDA framework, which integrates a set of standardized and widespread library technologies in order to increase the identification and traceability of physical items, such as books. The framework makes use of RFID tags in order to assign unique identification marks, in the form of URIs that can be globally exchanged. The framework has been implemented in the fully translated and customized Koha installation of our Library and its core services support checking in/out of books and browsing of history transactions with geospatial visualization. Its use can support transactions between various libraries or branches of the same library. The proposed presentation will describe the architecture of the framework and how it connects to Koha, as well as the challenges we faced during its development.

Evaluation is a very vital research interest in the digital library domain. This has been exhibited by the growth of the literature in the main conferences and journal papers. However it is very difficult for one to navigate in this extended corpus. For these reasons the DiLEO ontology has been developed in order to assist the exploration of important concepts and the discovery of trends in the evaluation of digital libraries. DiLEO is a domain ontology, which aims to conceptualize the DL evaluation domain by correlating its key entities and provide reasoning paths that support the design of evaluation experiments.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

2. structure
- introduction
- enquiry foundations
- definitions
- types of user studies
- usage studies
- behavior studies
- fundamental theories and models
- methodological considerations
2
4. definitions
- User studies are research studies focusing on the use of information
sources from “real” (end) users.
- User studies are extended on the channels of information, such as
means (formats), networks (social, academic, workplace networks) or
information providing systems (information retrieval systems, digital
libraries, web search systems, intranets, etc.).
- In user studies the use of information sources is considered the
dependent variable, while the various aspects of the users’ profile are
considered the independent variable.
4
5. variables
Dependent Independent
Usage age
> what is used sex
> how is used scientific area
> why it is used educational level
Users’ opinion communities
Users’ preference location
...
..
.
5
6. definition of context
- A rather vague and unclear term
- In the present example of a context
we identify:
- a person (implied)
- the mean (the computer and
information system)
- the content (which is supplied
by the information system)
- An already rich image of a
complex context.
6
7. definition of context
- By expanding our view we can
see:
- the ability to interact with
other information sources
and means.
- these means may pre-exist
and -may again - have
contributed to the formation
of the user’s context.
7
8. definition of interaction
- Direct / personal
- the user is interacting by his own means with an information
source.
- Direct / collaborative
- the user is cooperating with persons that understand the same or a
similar work need.
- Indirect / intermediated
- the user is supported by a third person for fulfilling his/her
information need.
8
9. definition of need
- Users needs are:
- information needs
- information needs are - usually - unclear and “messy”, while a
part of them may remain unexpressed and unfulfilled.
- information needs can be clarified or can be generated during
information seeking.
- work needs
- work needs are more clear and their satisfaction is imperative
and often takes place in pressing conditions.
- Obviously, information needs are included in work needs.
9
10. definition of need
- Needs affect several expressions of information behavior.
- Needs are related to motives and constraints in information seeking.
- According to Taylor [1986] needs are:
- Visceral
- Conscious
- Formalized
- Compromised
10
11. types of user studies
- User studies are distinguished in two broad categories:
- usage studies
- what, why and how much is used
- behavior studies
- how and why something is used
11
12. usage studies
- Usage studies are important for the area of libraries and related
information organizations.
- They have important practical significance and they can assist decision
making.
- They focus on usage patterns.
12
13. examples of findings
- ...one or two sessions per month, wide use of journals and articles, mostly
social scientists and graduate students...
- ...journal-focused (many sessions but concentrated on 4 or 5 specific journal
titles and 50% full text, mostly scientists and graduate -students)...
- ...topic-focused (searched less often and by subject rather than -specific
journals, used many articles, mostly social scientists...
- Clinicians and biology researchers use e-journals differently: clinicians search
online material (often abstracts) for educational and clinical purposes, while
biology researchers use online material for research. Health professionals
with an M.D. degree use abstracts rather than full-text articles to access
treatment protocols and say they would go without an article rather than pay
for online access. Those without the M.D. degree use e-journals even more
often.
Findings from SuperJournal and HighWire eJUSt (last bullet) studies as
reported in Tenopir [2003]
13
15. why?
- Cost-benefit decisions
- subscription/operational costs
- costs per use (download, view, etc.)
- Understanding users
15
16. user behavior studies
- Behavior studies are known in information science as “information
behavior” studies
- According to T.D. Wilson:
those activities a person may engage in when identifying their
own needs for information, searching for such information in
any way, and using or transferring that information.
- Information behavior is inclusive of all stages of information lifecycle
and is not constrained only in retrieval.
16
17. user behavior studies
- Information behavior refers to the environment in one user is acting
and his/her “primary” needs one attempts to cover.
- Various contributing areas:
- psychology, with emphasis in cognitive psychology and behavioral
psychology
- anthropology and linguistics
- communication-related sciences
- computer science, with emphasis in human-computer interaction
17
18. micro/macro behaviors
- Information searching: the sum of all
interactions of the user with the system
on two levels (a mental and a physical,
i.e. the communication between a user
information
and a machine’s parts).
behavior
- related concepts: search, browse,
relevance, serendipity, keystroke information
level failures, multi-tasking, etc. seeking
- Information seeking: the intentional and
targeted seeking of information as driven
information
by a primary level.
searching
- related concepts: filtering, sharing,
collaborating
Figure by Wilson
18
19. interaction ground
- The differences between the:
- organized and certain state of a system.
- unclear and uncertain state of user.
- these particular differences express a certain paradigm, which
is called the “bibliographic paradigm”
- the advent of new information-organizing features, e.g.
information architecture or knowledge organization features, has
lessened these differences.
19
20. fundamental theories & models
- Belkin’s Anomalous State of Knowledge (ASK)
- Dervin’s Sense Making
- Bates Berrypicking
- Ellis & Haugan’s model for Information Seeking
- Kuhlhau’s Information Search Process
- Wilson’s extended model of IB
20
21. anomalous state of knowledge
- Belkin’s anomalous state of knowledge is based on the discrete mental
models of the information system and the user.
- According to the model, there is an anomalous state of knowledge when
the user can not resolve an information need based only on her
existing knowledge. ASK reinforces uncertainty.
21
22. ASK-coping IR systems
1. Statement of problem
2. Structural analysis of the statement
3. Choice of retrieval strategy according to type of ASK
4. Abstract presented to user simultaneously with explanations
5. Structured dialog between system and user to infer user’s evaluation of
a. Method of choice
b. Suitability of document to problem
c. Whether need has changed
6. Modifications based on evaluation or conclusion
7. Return to 2 or 3 if needed
22
23. Dervin’s Sense-Making
- Emphasized on the internal (cognitive) and
the external (procedural) aspects of
situation
information seeking.
- A methodology rather than a model. Four
methods:
gap outcome
- Micro-Moment Time-Line Interview
- Help/Hurt chaining
- Close-ended Sense-Making Interview
- Message Q/ing Interview
- Information seeking is a cognitive process
evolved over time and space (a context) in
support of resolving a knowledge gap for
certain uses (desired outcomes).
- Each component has different variables.
23
24. Bates’ Berrypicking
- Differed from the traditional IR
process:
- Nature of the query.
- Nature of the overall search document
process.
- Range of search techniques

26. Ellis & Haugan
- Ellis and Haugan do not refer to stages.
- They discuss on the characteristics of information seeking, which can
be inter-related.
- These features refer to both micro and macro behavior level.
- Their model has a strong validation grounded on empirical studies.
- Wilson attempted to depict their model as a process.

27. Kuhlthau’s Information Search Process
- The relation of cognitive and affective structures of user during the
information search process (ISP).
- The rationale is:
- at the early stages of information searching process there is a
feeling of uncertainty (linked with the unclear state of user).
- gradually the cognitive state of the user is improved.
- during the later stages certainty gains ground.
- The cognitive changes are developed between the stages of resolution
of an information need.
- The affective changes are developed according to the stages of
searching.

31. a synopsis
- The previous models have established basic theories of information
science and have fueled other models in IR.
- Some of them are linear, following a time-dependent sequence of
actions.
- A few have empirical validation.
- The majority of these are generic models, which have been applied
mainly in Information Retrieval system, due to various reasons (mainly
proximity).
- The explanation of user behavior is useful:
- support system design
- support information literacy
- support community practices
