Reference Scenario


Reference Scenario (RS) is an imagined situation where a library patron brings a question to a librarian and there is then a conversation, called in the field a reference interview, where the librarian works to help the patron find what he or she wants. There are three (3) reference scenarios in this activity containing question and sentences describing the situation that underlies that question.

Instruction:
Describe the interactive process in question negotiations, searching strategies and analytical skills as well as behavioral attributes of the librarian you observed during the reference interview. Determine ways in which communication skills in the reference interview might be improved in face-to-face or online interaction. Document the reference encounter to support your assertions based on the ALA Reference User Services Association (RUSA).

RS1
Library User: I want some information on H1N1 (Swine Flu)?
Background: You are a father/mother who has heard that H1N1 is still active in Malaysia. You learned that a school classmate of your child is infected with the disease. You want to know to be able to tell if your child may have H1N1 and want to know the symptoms and treatments.

Virtual Reference

Virtual reference is reference service initiated electronically, often in real-time, where patrons employ computers or other Internet technology to communicate with reference staff, without being physically present. Communication channels used frequently in virtual reference include chat, videoconferencing, Voice over IP, co-browsing, e-mail, and instant messaging. While online sources are often utilized in provision of virtual reference, use of electronic sources in seeking answers is not of itself virtual reference. Virtual reference queries are sometimes followed-up with telephone, fax, in-person and regular mail interactions, even though these modes of communication are not considered virtual.

I chose online chat as my communication channel with the librarian. And I’ve also received an e-mail with attachment of the chat transcript after the chat ended.

Guidelines for Behavioral Performance of Reference and Information Service Providers

(Revised by MOUSS Management of Reference Committee and approved by the RUSA Board of Directors, June 2004.)

Remote reference service - Additional guidelines that are specific to reference encounters by telephone, email, chat, etc., where traditional visual and non-verbal cues do not exist.
Five behavioral attributes - Approachability, Interest, Listening/Inquiring, Searching, and Follow Up.

Approachability
In order to have a successful reference transaction, patrons must be able to identify that a reference librarian is available to provide assistance and also must feel comfortable in going to that person for help. In remote environments, this also means placing contact information for chat, email, telephone, and other services in prominent locations, to make them obvious and welcoming to patrons. Approachability behaviors, such as the initial verbal and non-verbal responses of the librarian, will set the tone for the entire communication process, and will influence the depth and level of interaction between the staff and the patrons. At this stage in the process, the behaviors exhibited by the staff member should serve to welcome the patrons and to place them at ease. The librarian's role in the communications process is to make the patrons feel comfortable in a situation that may be perceived as intimidating, risky, confusing, and overwhelming. To be approachable, the librarian:
-Should provide prominent, jargon-free links to all forms of reference services from the home page of the library's Web site, and throughout the site wherever research assistance may be sought out. The Web should be used to make reference services easy to find and convenient.

As of this assignment, I’ve tried three chat sessions with three different libraries. I found out that the New York Public Library gave the best services as they gave quick responses after I enter the chat session compared to the other library which gave really late responses and no response at all for the other library. The librarians also introduced her name and start the conversation by asking of what she can help me with.

Interest
A successful librarian must demonstrate a high degree of interest in the reference transaction. While not every query will contain stimulating intellectual challenges, the librarian should be interested in each patron's informational need and should be committed to providing the most effective assistance. Librarians who demonstrate a high level of interest in the inquiries of their patrons will generate a higher level of satisfaction among users. To demonstrate interest, the librarian:
-Maintains or re-establishes "word contact" with the patron in text-based environments by sending written or prepared prompts, etc., to convey interest in the patron's question.
-Acknowledges user email questions in a timely manner.
-States question-answering procedures and policies clearly in an accessible place on the Web. This should indicate question scope; types of answers provided and expected turnaround time.

In my reference scenario case, the librarian did state their policies as I asked about medical advice or opinions. The librarian state that they are prohibited by law from offering medical advice or opinions. But the librarian gave me informative site regarding consumer health and advice me to contact health professional regarding my question.

Listening/Inquiring
The reference interview is the heart of the reference transaction and is crucial to the success of the process. The librarian must be effective in identifying the patron's information needs and must do so in a manner that keeps patrons at ease. Strong listening and questioning skills are necessary for a positive interaction. As a good communicator, the librarian:
-Uses reference interviews or Web forms to gather as much information as possible without compromising user privacy.

The librarian somehow did not ask as much information because my first question is quite general (i.e. I want some information on H1N1 (Swine Flu)? ). But the librarian did ask whether the sources I need is for research/personal opinion. As I gave detail information about my background, she gave responses and proposes suitable resources for my question.

Searching
The search process is the portion of the transaction in which behavior and accuracy intersect. Without an effective search, not only is the desired information unlikely to be found, but patrons may become discouraged as well. Yet many of the aspects of searching that lead to accurate results are still dependent on the behavior of the librarian. As an effective searcher, the librarian:
-Uses appropriate technology (such as co-browsing, scanning, faxing, etc.) to help guide patrons through library resources, when possible.

The librarian gave only web resources because my medium of interaction is just through online chat. If I enhanced my communication through e-mail or telephone, I might be able to receive various sources such as scanned, faxed and electronic resources.

Follow-up
The reference transaction does not end when the librarian leaves the patrons. The librarian is responsible for determining if the patrons are satisfied with the results of the search, and is also responsible for referring the patrons to other sources, even when those sources are not available in the local library. For successful follow-up, the librarian:
-Suggests that the patrons visit or call the library when appropriate.

The librarian did ask whether she gave enough information and suggest that I login again anytime if I have more questions.

Ways to improve online interaction communication skills in reference interview.

The librarian uses open-ended questioning techniques to encourage patrons to expand on the request or present additional information.
-Please tell me more about your topic.
-What additional information can you give me?
-How much information do you need?

The librarian uses closed and/or clarifying questions to refine the search query. Some examples of clarifying questions are:
-What have you already found?
-What type of information do you need (books, articles, etc.)?
-Do you need current or historical information?

Neutral questioning was developed to improve reference interviewing outcomes. Neutral questions are also known as “sense-making questions”. They “provide more structure than open questions, but are less likely to lead to premature diagnosis than closed questions. Sample questions include:
-Can you describe the kind of information you would like to find?
-Is there a specific question you are trying to answer?
-What are you hoping to find?
-Tell me what you’re ultimately trying to do, so I can head in the right direction.
-Can you give me a little background on your interest in this?

Search Engines


Definition
-Britannica Concise Encyclopedia
Tool for finding information, especially on the Internet or World Wide Web. Search engines are essentially massive databases that cover wide swaths of the Internet. Most consist of three parts: at least one program, called a spider, crawler, or bot, which "crawls" through the Internet gathering information; a database, which stores the gathered information; and a search tool, with which users search through the database by typing in keywords describing the information desired (usually at a Web site dedicated to the search engine).


Program that scans or "crawls" through Web pages, classifying and indexing them based on a set of pre-determined criteria.

Search engines help organize the more than two billion pages of information on the World Wide Web and make them accessible to Internet users. Search engines are the primary method Internet surfers use to locate information on the Web. In fact, Karl Greenberg noted in Brandweek that 85 percent of Internet surfers use search engines to locate information online. Search engines generate the largest percentage of new traffic to Web pages, followed by links from other sites, printed media, and word of mouth.

How to use Search Engine

-Keyword searching
This is the most common form of text search on the Web. Most search engines do their text query and retrieval using keywords. Keyword can simply be any word on a webpage. Words that are mentioned towards the beginning of a document are given more weight by most search engines. The same goes for words that are repeated several times throughout the document. Some search engines index every word on every page. Others index only part of the document. Full-text indexing systems generally pick up every word in the text except commonly occurring stop words such as "a", "an", "the", "is", "and", "or" and "www." Some of the search engines discriminate upper case from lower case; others store all words without reference to capitalization.

-Refining your search
Most sites offer two different types of searches--"basic" and "refined" or "advanced." In a "basic" search, just enter a keyword without sifting through any pull down menus of additional options. Depending on the engine, though, "basic" searches can be quite complex. Advanced search refining options differ from one search engine to another, but some of the possibilities include the ability to search on more than one word, to give more weight to one search term than you give to another, and to exclude words that might be likely to muddy the results. Some search engines also allow users to specify what form they'd like your results to appear in, and whether users wish to restrict their search to certain fields on the internet (i.e., usenet or the Web) or to specific parts of Web documents (i.e., the title or URL). Many, but not all search engines allow users to use so-called Boolean operators to refine your search. These are the logical terms AND, OR, NOT, and the so-called proximal locators, NEAR and FOLLOWED BY. Some search engines use the characters + and - instead of Boolean operators to include and exclude terms. The ability to query on phrases is very important in a search engine. Those that allow it usually require to enclose the phrase in quotation marks, i.e., "space the final frontier."

-Relevancy rankings
Most of the search engines return results with confidence or relevancy rankings. In other words, they list the hits according to how closely they think the results match the query. Most search engines use search term frequency as a primary way of determining whether a document is relevant. If you're researching diabetes and the word "diabetes" appears multiple times in a Web document, it's reasonable to assume that the document will contain useful information. Therefore, a document that repeats the word "diabetes" over and over is likely to turn up near the top of your list. If your keyword is a common one, or if it has multiple other meanings, you could end up with a lot of irrelevant hits. And if your keyword is a subject about which you desire information, you don't need to see it repeated over and over--it's the information about that word that you're interested in, not the word itself. Some search engines consider both the frequency and the positioning of keywords to determine relevancy, reasoning that if the keywords appear early in the document, or in the headers, this increases the likelihood that the document is on target.

Activity 4 : Question 2


:: Federated Search ::

Definition

Federated searching is a simultaneous search of multiple online databases or web resources and is an emerging feature of automated, web-based library and information retrieval systems. It works as a tool to help users identify the databases that are best suited to the subjects they are researching. It allows users to search across multiple resources: subscription databases, library catalogs, and web sites. It has other names as well - metasearch, parallel search, broadcast searching.

There is a large amount of content that is not available to crawl-type search engines like Google. Federated search engines, in particular ones that perform deep web searches, are required to access this additional content like scientific, technical, and business databases.

Federated searching consists of:
(1) Transforming a query and broadcasting it to a group of disparate databases or other web resources, with the appropriate syntax
(2) Merging the results collected from the databases
(3) Presenting them in a succinct and unified format with minimal duplication
(4) Providing a means, performed either automatically or by the portal user, to sort the merged result set.


Technologies

Federated search software uses standardized protocols to access databases. The most common protocol used is Z39.50. Some target databases that do not comply with the Z39.50 standard can still be searched using "translator" programs that convert the query format of the federated system into the format of the native system. However, many information resources do not make their query protocols public, and thus they cannot be searched using a federated search engine. The search results that are retrieved from various targets may be deduplicated to reduce extraneous results. Some systems also rank results by relevancy or permit some other type of sorting.

User authentication is another necessary technology for federated search systems. This stems from the use of licensing agreements that libraries sign with vendors. These agreements typically limit access to certain groups or numbers of users affiliated with an institution or consortia.


How federated search works

Federated search engines use software "connectors" to access information sources. The federated search engine takes the user's search query, transforms the search terms to match each content source's requirements, and submits the query to each of the sources simultaneously. When the search results come back from each of the sources, the federated search engine merges them together, modifying the look and feel of each of the result pages to have a single look and feel.

A connector is a piece of software that is written to access a content source. A connector must know the URL of the source, how to send search commands, what the search syntax is, and how to process the search results that are returned from a source. Connectors can be challenging to write if access to a source requires handling multiple steps, URL redirection, cookies, sessions, or authentication methods.

A web patron seeking science information comes to a gateway site, like Science.gov, and enters a query. The query is transmitted to the gateway server and then it is fanned out to a suite of databases across the entire world. At each database, the query launches a search and brings back a hit list. The list is then transmitted back to the gateway server, where the hits are relevancy ranked and presented to the web patron. So, in the span of about 20 seconds, the query is transmitted to numerous databases, searches are executed at numerous databases, and the results are brought back and ranked for the patron.

Federated search drills down to the deep web where scientific databases reside. Unlike the popular search engines, federated search places no burden on the database owners.


Organizations

Science Accelerator is a gateway to science, including R&D results, project descriptions, accomplishments, and more, via resources made available by the Office of Scientific and Technical Information (OSTI), U.S. Department of Energy. Science Accelerator was developed and is made available by OSTI as a free public service.

Science.gov is a gateway to government science information and research results. Currently in its fifth generation, Science.gov provides a search of over 40 scientific databases and 200 million pages of science information with just one query, and is a gateway to 1,950+ scientific websites.

WorldWideScience.org is a global science gateway connecting users to national and international scientific databases and portals. WorldWideScience.org accelerates scientific discovery and progress by providing one-stop searching of global science sources. The WorldWideScience Alliance, a multilateral partnership, consists of participating member countries and provides the governance structure for WorldWideScience.org.

Deep Web Technologies host a federated search application in their data center and deploy it in hosting environment. Additionally, they can maintain customer’s application, including monitoring and updating of connectors as needed. They also provide a needs assessment, consulting services, deployment and maintenance training, custom software development and look-and-feel design service. Deep Web Technologies' flagship product is its Explorit Research Accelerator federated search application. The product can be customized for specialized customer needs, both in terms of look-and-feel and to add functionality. Deep Web Technologies develops connectors for a wide range of content databases and will create custom connectors to meet customer’s needs.


Strengths

1. One search interface for multiple resources from different database providers eliminates the need for the user to learn how to use the different search interfaces of all the individual databases.
2. Increasing the size of the collection searched may help improve the number of articles retrieved.
3. The searcher may be exposed to relevant content from resources that s/he may not have been familiar with.


Limitations

1. The lack of a uniform authentication standard means that some databases are inaccessible to federated search engines.
2. True, full, deduplication is impossible because databases download results in small sets and metadata standards vary by resource.
3. Relevancy ranking is limited by the quality of the metadata, which usually does not include abstracts or full-text information.
4. Although federated search systems are fundamentally software, they must be implemented and managed as a service, which takes a great deal of resources.
5. Federated search engines cannot improve on the native interface in terms of search accuracy and precision.

Annotated Webliography


:: Annotated Webliography ::
By : Noor Husna binti Mohamad Zayadi (WGB090005)
Topic : Health, Medical and Medicine

Health is "a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity".

Medicine is the art and science of healing. It encompasses a range of health care practices evolved to maintain and restore health by the prevention and treatment of illness.

The importance of health and wellness has certainly come to the forefront of the health industry in the last decade. It is reflected by the fact that diets, weight loss programs, exercise programs and equipment, fitness facilities, spas, nutritional supplements and activity/leisure groups of all sorts are now commonplace in our everyday lives. Some of these changes are driven by the extreme demands and long waits for treatment in the health care system, but also by the desire of the working generation for a more active lifestyle after retirement, with the hope of being fit and well enough to participate in their chosen activities. For these goals to manifest into reality the base of good health must be built up throughout life, not just to try to repair the damage after it's been done.

This webliography compiles 25 websites and online articles of 25 different aspects/topics of health, medical and medicine. It is arranged alphabetically by topics and each entry contains few lines of information about the website/article and it's URL.
