The document discusses the evaluation of information retrieval systems. Evaluation is defined as systematically determining a subject's merit using a set of standards. The main purposes of evaluation are to compare the performance of different systems, assess how well systems meet their goals, and identify ways to improve effectiveness. Evaluation can consider managerial or user viewpoints. Common criteria include recall, precision, fallout, generality, effectiveness, efficiency, usability, satisfaction, and cost. Recall measures the proportion of relevant documents retrieved while precision measures the proportion of retrieved documents that are relevant. Evaluation helps identify ways to improve information retrieval system performance.
An introductory presentation on the concept of Library Classification by Dr. Keshava, Professor, Department of Studies and Research in Library and Information Science, Tumkur University, Karnataka, INDIA.
This PPT contain details of Z39.50 and useful for Library Science students. This protocol used for information retrieval and in the end list of different types of protocols are given.
Library automation refers to the implementation of information and communications technologies (ICT) in the libraries and information centres for replacing manual library operations. The term automation is used for any process which is done through input and output operation. Library automation system includes maintenance of large bibliographical database. The status of library automation depends on Interaction between human and computer to accomplish various tasks of the library automation systems. In order to provide and also to enable the records in the database. The international standards for bibliographic description of library automation system uses sophisticated software tools and standard to index search and display information from the database created.
These slides contain various sections in libraries and their functions including ICT devices that can be used to perform these functions in the 21st century.
A comparative analysis of library classification systemsAli Hassan Maken
We use classification each & every moment of the life by intentionally or unintentionally. Classification has always been the backbone of all Library operations and without it, library is definitely going to suffer in its recourse and to find a particular piece of information from unorganized heap of knowledge is almost impossible. The library classification is core instrument for organizing and retrieval of the documents stored in a library. At present era they are the navigation tools for locating and retrieving documents in more precisely and relevantly. The electronic versions of the DDC and UDC and other classification schemes make it possible to realize the potential of library classification to improve subject retrieval.
Information repackaging is a process to repackage the analyzed, consolidate information in that form which is more suitable & usable for library users. Customization of information taking into account the needs and characteristics of the individual or user groups and matching them with the information to be provided so that diffusion of information occurs.

From Position Management to Performance Management….
Position Management:
emphasizing analyzing jobs,
establishing essential duties and responsibilities,
determining necessary knowledge, skills and abilities,
classifying jobs, setting a pay scale,
and using the position as a critical feature of financial management
It could all be done without a single reference to a real live person.
Any deliberate act intended to affect employee performance falls’ under the category of Performance Management.
Formal performance appraisal provides employees with feedback on their work.
Because this leads to organizational decisions regarding promotion and pay the process becomes more complicated:
As it is accompanied by heightened legal scrutiny for civil rights violations and demands for reasons behind the decisions.

Performance appraisal is directed toward technical and management goals but rarely toward employee aspirations.
The technical part focuses on developing an instrument that accurately mea ...

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

2. INTRODUCTION
Evaluation is a systematic determination of a subject's merit, worth
and significance, using criteria governed by a set of standards.
It ascertain the degree of achievement in regard to the aim and
objectives and results of any such action that has been completed.
Evaluation of information retrieval system measure which of the two
existing system perform better and try to assess how the level of
performance of a given can be improved.
Lancaster state that evaluation of information retrieval system can be
justified by the following three issues:
How well the system is satisfying its objectives
How efficiently it is satisfying its objectives and
Whether the system justified its existence.
3. PURPOSE OF EVALUATION
The main purpose of the evaluation is to focus on the process of
implementation rather than on its impact.
Evaluation studies also investigate the degree to which the state goals
have been achieved to which these can be achieved.
To measure information retrieval effectiveness in the standard
way, we need a test collection consisting of three things:
A document collection.
A test suite of information needs, expressible as queries.
A set of relevance judgments, standardly a binary assessment of
either relevant or non relevant for each query-document pair.
4. PURPOSE OF EVALUATION
Swanson state seven purposes for evaluation:
To assess a set of goals, a programme plan, or a design prior to
implementation.
To determine whether and how well goals or performance
expectation are being fulfilled.
To determine specific reasons for success and failure.
To uncover principles underlying a successful programme.
To explore technique for increasing programme effectiveness.
To established a foundation of further research on the reason for
the relative success of alternative technique and
To improve the means employed for attaining objectives or to
redefine sub goals or goals in view of research findings.
5. PURPOSE OF EVALUATION
Keen give three major purpose of evaluation for an information
retrieval system:
The need for measures with which to make merit comparisons
within a single test situation. In other words, evaluation studies
are conducted to compare the merits or demerits of two or more
system.
The need for measure with which to make comparison between
results obtained in different test situation and
The need for assessing the merit of a real-life system.
6. EVALUATION CRITERIA
Evaluation of Information Retrieval can be conduct into two
different viewpoints.
Managerial viewpoint: when evaluation is conducted from
managerial point of view it is called managerial oriented
evaluation.
User viewpoint: when evaluation is conducted from the user point
of view it is called user-oriented evaluation study.
7. EVALUATION CRITERIA
Lancaster in 1971 proposed five Evaluation Criteria
Coverage of the system
Ability of the system to retrieve wanted items (i.e. recall).
Ability of the system to avoid retrieval of unwanted items (i.e.
precision).
The response time of the system and
The amount of effort required by the user.
9. EVALUATION CRITERIA
Recall
Recall is defined as the proportion of the total relevant documents
that is retrieved.
Number of relevant item retrieved
Recall=——————————————————————x 100
Total number of relevant items in the collection
Example If there are 100 documents in a collection that are relevant
to a given query and 60 of these items are retrieved in a given
search, then the recall is state to be 60% in other words the system
has been able to retrieve 60% of the relevant items.
10. 60
Recall= ———x 100
100
Recall= 60%
Total number of relevant items in the collection=100
Number of relevant item retrieved=60

Total no. of relevent
items
no. of relevent items
11. EVALUATION CRITERIA
Precision
Precision is defined as the proportion of documents retrieved that is
relevant.
Number of relevant item retrieved
Precision=——————————————————x 100
Total number of items retrieved
Example In a given search the system retrieves 80 items, out of
which 40 are relevant and 40 are non-relevant, the precision is 50%.
12. 40
Precision= —————x 100

Relevant Not-relevant Total
Retrieved a (hints) b (noise) a+b
Not-retrieved c (misses) d rejected c+d
Total a+c b+d a+b+c+d
14. EVALUATION CRITERIA
Fallout
Fallout ratio is the proportion of non-relevant items that has been
retrieved in a given search.
Generality
Generality ratio is the relevant items that have been retrieved in a
given search.
15. Retrieval Measure
Symbol Evaluation measure Formula Explanation
R Recall a/(a+c) Proportion of relevant
items retrieved
P Precision a/(a+b) Proportion of retrieved
item that are relevant
F Fallout b/(b+d) Proportion of non-relevant
items retrieved
G Generality (a+c)/(a+b+c+d) Proportion of relevant
items per query
16. LIMITATIONS OF RECALL AND
PRECISION
Different users may want different levels of recall.
A person going to prepare a state-of-the-art report on a topic would
like to have all the items available on the topics and therefore will go
for high recall.
Where as a user wanting to know about a given topic will prefer to
have a few items and thus will not require a high recall.
18. OTHER EVALUATION CRITERIA
Effectiveness
Effectiveness means the level up to which the given system attained
its objectives.
In an information retrieval system effectiveness may be measure of
how far it can retrieve relevant information while with-holding non-
relevant information.
Efficiency
Efficiency means how economically the system is achieving its
objectives.
In an information retrieval system efficiency can be measured be
factor such as cost.
Cost include factor such as response time, time taken by the system
to provide an answer.
19. OTHER EVALUATION CRITERIA
Usability
Measure that embraces the interface through which the user interacts
with the system.
Takes into account the user and their expectations, skills and
experiences.
Satisfaction
Search task
Search setting
The searcher’s state contributes to quality and satisfaction judgments
in digital environments.
Other perspectives on satisfaction are to be found in the service
quality and website quality literatures.
20. OTHER EVALUATION CRITERIA
Cost
Users may experience costs in terms of any payment that they need
to make for system or document access.
Most significant cost is associated with the time that they spend in
searching a system.
21. CONCLUSION
Evaluation is a systematic determination of a subject's merit, worth
and significance, using criteria governed by a set of standards.
Effectiveness and efficiency are two basic parameter for measuring
the performance of system.
Evaluation criteria
Managerial viewpoint: when evaluation is conducted from
managerial point of view it is called managerial oriented
evaluation.
User viewpoint: when evaluation is conducted from the user point
of view it is called user-oriented evaluation study.
