ASSALAMUAAIKUM,

HYE NICE TO MEET Y0u,

This week I would like to talk about Introduction to of Information Analysis. I hope you will be interesting with explanation. Okay. How are you guys? I hope you will be fine. If you sick just take a medicine. Okay. This week I  felt too tried coz I have a lot of thing that I need to do.

Now is time to explain about this topic!!!

EVALUATE

Now that anyone with access to a server and a passing knowledge of HTML (Hypertext Markup Language) can put information on the Internet. Information can be spread over the Internet by anyone without regard to accuracy, validity, or bias. Although many of the traditional principles of collection development of printed materials. For librarians and library users to make effective use of the Internet, they need criteria to use in evaluating the information found. Without explicit criteria for selection of these sources, libraries risk wasting their users' time with tools of dubious value.

Criteria for evaluating Resources

• Resources should be evaluated on the basis of the following

       broad levels of analysis:

• —  If a site provides its own mission statement, the user can verify whether the content matches this statement

• —  A good resource will not be ambiguous and will not deflect potential users, due to its poor communication of  purpose.

Authority

Institution

•         Is this the official site of an organization or association?

•         Is the publisher a  recognized organization?

•         On which server is the site mounted? Is it reputable? Sponsored?

•         Does the address, specifically the domain, suggest the perspective from which the site was designed and does this suit our purpose?

For example, ".edu," ".com," ".gov" respectively imply education, commercial, and government origins - a tilde "~" usually indicates a personal web directory, thereby reflecting a personal rather than institutional viewpoint.

Resource

•         Is the information credible and of high quality?

•         Is the information objective?

•         Is there an obvious bias? Is this site designed for promotional purposes?

•         How long has a resource been available (either in print or as an electronic version)?

•         Is the information verifiable?

•         Does the resource document the sources the information is based on and how that information was obtained?

•         The site should have the confidence to offer a feedback facility such as a form, preferably with e-mail and postal addresses as well.

Audience

• —  Who are the intended users of this resource?

• —  At what level is the resource pitched: a subject expert, a layperson, or a school student?

• —  Will the resource satisfy the needs of the intended users?

—  Does your user group correspond to the intended audience?

Information Content

Accuracy

·        Is the information in the resource accurate? check this against other resources, or by checking some information about which you have special knowledge.

Currency

·        Different parts of web sites may be updated at different times. For example, e-journals, news sections, bulletin boards, and any section dedicated to new information should .Fast moving fields produce more new information and need more frequent updates.

·        A six month interval is the maximum acceptable period between updates regardless of disciplined be updated fairly frequently.

Uniqueness

◦      A particular site may not be available when required, and an alternative or mirror site may have to be used .

◦      Redundancy may be valuable on the Internet.

◦      Librarians in the Internet environment will need to become familiar with the strengths and weaknesses of the range of sources reviewing Internet resources.

Quality of writing   

◦      While hypertext linking and multimedia are important elements of the Web, the bulk of the information content on the Web still lies in text, and quality of writing is important for the content to be communicated clearly.

Design and layout

Organization

•         How big is the resource? - If a resource is particularly large, it should really be sensibly and logically divided into unique and separate segments of information with go the balance of links and text good? - A Web document that has a vast tree of links is difficult to navigate and overwhelming to the eye.

•         Is there a consistent look and feel from one page to another? - Visual similarities in all sections navigation links between each segment.

Navigability.

•         Can you find your way around and easily locate a particular page from any other page?

•         Are there enough internal links?

•         If the value of the site lies in its links to other resources, are the links kept up to date, and made  to appropriate resources?

Style & Functionalist.

• —  Whatever the level of technology employed, it must function well and allow the user to progress logically through the information.

• —  A very simple, classic design can appeal as much as a clever, graphically innovative one.

Colour

• —  Are the text and background colour choices contrasting enough for the text to be easily read?

• —  Is the background plain enough for the text to be easily read?

• —  Are backgrounds or other visual elements distracting or cluttered?

Multimedia

◦      If the site is multimedia, consider creativity, quality of the image and sound, and interactivity.

◦      Good web sites weave together relevant text, audio, video, and still images to give users a rich experience.

Ease of use….

•         For interactive sites, such as databases and search engines, it is vital that 'Help' on how to use the system is readily available

•         How usable is the site? Can visitors get the information they need within a reasonable number of links - preferably 3 or  fewer clicks

•         Does it encourage you to explore further? - A good resource should encourage exploration.

Browsability.

• —  It is useful to test resources with a variety of browsers and connections.

ü Telnet resources may pose problems to users who have not installed a telnet client.

ü Images and other multimedia may create problems if users have not installed the correct viewer.

Connectivity

• —  If more than one user will need to access a site, consider each users' access and "functionality."

• —  How long does it take to download? - Particularly one which heavily relies on graphics, is a particularly long textual document, or is a large piece of software. Provide a warning to indicate its size and potential transfer time.

Copyright/Censorship/Encryption

• —  Does your institution, based on its mission, parent organization or space limitations, apply some restrictions to Internet use

• —  Even if the copyright notice does not appear prominently, someone wrote, or is responsible for, the creation of a document, graphic, sound or image, and the material falls under the copyright conventions.

Criteria…

• —  This indicates that appearance is widely regarded as important, even among sites that are primarily concerned with content.

• —  The organization of the site and ease with which users can find their way around are also seen as important in the Internet environment.

• —  All evaluation sites included some aspect of content and workability.

• —  The traditional reference librarian's criteria of currency, authority, and audience are also widely used.

HI…..Ihope you will understand hat I already explain to you just now,,,,
