ABSTRACT

The access and scope of Online and CD ROM searching changed due to the advent of World Wide Web and the increase in the computer industry research and development of high-density recording techniques. From CD ROM stand alone systems to remote availability of resources on web, improvement on information retrieval is noteworthy as there existed a drastic booming on various free-access or with-fee online search services from online vendors all over the world, that have specially designed interfaces and search features that make the user searching easier and profitable.

THINGS I HAVE LEARNED

CD ROM and Online Search Services system has its own search features and interfaces that would greatly influence and relate to the user search capabilities. Although the searching on these systems were made easy, the user still need to have knowledge or familiarization with these its system aspects, learn to formulate appropriate search expression and reinvent it until the satisfactory or optimum results are attained. The use of command language such as Boolean operator is also applicable for these types of retrieval systems. Price is always a major concern for both CD ROM and Online Information retrieval.

IMPLICATIONS OF WHAT I HAVE LEARNED

In my institution, I do online searching to check the details of some new songs. Doing online searching is very helpful to me because I am always positive that in my every search I will be getting the most recent information I wanted since online information are most likely up-to-date. Thus, if ever I need to make some corrections regarding the details of any material, I can easily provide the exact details of it (provided that the network connection is stable). And if I am still in doubt regarding the material details I got, I can easily make comparisons of content or information from the sites based on the evaluation of source cited and authorship (determining which among those sites is the most authoritative).

For me, I can say that I still CD-ee Future of some CD ROMs in the up-coming years. I believe that, with the aid of technology, people in the computer industry would still give effort to do researches on the high end recording techniques, hence, there are still chance that they could develop optical disks with high capacity and longer usability as storage device. Although we cannot normally get the recent information from CD ROM based system (since updates are available only through purchase of new CD ROMS every now and then) still retaining these materials will be beneficial for us because we can have source of information that we can access anytime without needing any network connection or working online---- I think information on these formats are useful because it can somehow readily answer basic factual information query (those not in need of very detailed inputs) like encyclopedias and dictionaries on discs. Although data lost could occur if discs are used frequently; but in a normal function, we could maximize its use and retain it until five years.

Although I am not using CD ROM based in my institution, given a chance I want to try this CD ROM based services if ever there will be available materials that might call my clientele interests. Retrieval wise, I can say that the response time of CD ROM would be shorter than ONLINE because online based search do retrieve for information on almost all databases available on web while CD ROM are subject specific and bound to discs.

It can never be denied that we are now continuing ON LINEage, hence, whether or not we like it, more or less we will be using web based system, since information here are adequately available and accessible anytime and anywhere provided that you have the computer that is capable of networking and also the other facilities required.

We can never go wrong with being traditional. CD ROM is useful, information from this can be use as supplements and back ups of whatever we have online. It is the safest source when the online system went down. Although the initial cost of this system is expensive. I guess it would still be worth the price in a long run.

Having said all these, I think it is a better to have a mindset that are open to possibilities and options that we could put these materials together, get a grasp of its usability to the extent of our abilities.

We should learn how to CD-ee the future ON LINEage. We should see the future on the connections (lineage) of these materials. It is true that these materials might not provide same inputs because information from here varies, but I do believe that with the aid of technological “continuity on lineage (from printed-CD ROM based to online)”------ whatever differences that these technologies will have now will meet in same context in the end, this is, to prepare us to CDee future to get ONLINE with development. ^_^ Hence, it is not awful to get a balance of both technological advancements----- the old and the latest, nevertheless the usefulness of these materials will more or less, would really depend on us, not just on the interfaces or information that they provide, but also based on how we see, understand and evaluate how useful the information we got from it. ^_^

Strategies in Effective Searching of Information?

Strategies for You and For me...

Strategies for Everybody?

It was a stormy day for all of us last Wednesday. No one had expected that its going to be a one "HELLen" of a day---a day of struggle for each of us who have given their best to battle the angst of the tremendously pouring wind and rain just to attend the forum in Mandaluyong, with hope that we will learn something new that we could later impart to our institutions.

The presentation was very informative for information professionals who are not familliar with the existing reference sources on web. However, for groups who are quite knowledgeable with the references presented, the entire forum would be somehow insipid.

I guess the forum should have focused more on the "strategies per se" in effective searching.. and not with the resources available on web. It should have taught or informed at least the attendees on the latest and existing search strategies that could help them in maximizing the uses of those resources cited from web. Although, some a bit new strategies terms had been mentioned--like path finders ( quite same with bookmarking we discussed in Web 2.0?).

The information presented were quite inadequate to suffice the needed information of information profesionals who went all the way from different parts of the metro and even for individuals who came all the way from the Northern parts of the Philippines. It would have been better if the forum title was just changed to "Reference Sources on Web: Aid for Searching Information" rather than the one presented on "Strategies"... so that they could at least minimimized the amount of expectations withdrawn by the forum attendees way before they came for the forum.

Its a fact that not everyone are that sufficiently informed about the technological advances at present..but i guess, being part of the information professional communities, and being an information professional alone---had offered you advantages and responsibility to somehow take the initiative to know those things-- and implement it on your institution to help the user communities. And formulating or implementing it to an educational program requires you to have a stern plan on how you will implement it; and also on how you will know that it is effective also requires regular evaluation, and demands cooperation from the parent institution's faculty and administration. We, as information professionals should always present our initiative and be affirmative with our plans. There should be no room for uncertainties.We should know how to uplift our profession.

I agree that anyone could post anything on Web, but it does not mean that most of the thing there are not reliable. Information on Web are almost the same information from the printed materials--- a more advance way of presenting information. Information from printed materials is incomparable, but still it should not draw our interest away from the good resources that we could also find on Web. Its nicer to have a balance of both.. i believe we have our inquisitive minds to know what references are scholarly and what are not. We are surrounded by fast-changing informations, and Information is our LIVES FUEL, hence, Every second counts... No time to waste..Everyone should learn.

Although we are not able to hear and see what we have expected... it still had left a very important fact for all of us. LITERACY IS IMPORTANT.. not just for information professional but most importantly to the community that we are catering. Hence, its a must to each of us to take our part and do our best to help them be productive and knowledgable individuals for a better society.

More over, the forum presented a fact that it is not bad to be traditional.. and Its not bad to take sometime to look back where we have once started. I believe you cannot tell that there have been development or changes that had happened if you're not aware of its past..agree? Would you agree?

I believe what ever advances we have now, we also owe it to the Traditional. Hence, we should still show our gratitude by finding ways on how we could help them. Not all are given a chance to be knowledgeable--- for us individuals who had enough chance to be one, let's help create an informative society and environment for them. Let's help. ^_^ Let us all be literate! ^_^

Its true that the forum might not have presented the recent strategies for information searching that we expected. Nevertheless, it still presented strategy--- strategy on how we should view and value information and opportunities given to us to be knowledgeable individuals.

...A Strategy not to be boastful about our knowledge but to be more considerate to those who are experiencing inadequacies. It gives us a chance to do some sharing strategy ^_^

A chance to share what we know and what we learned from the university-- a strategy for you, for me, and for everybody.

Web 2.0 Technologies in the Library

Web 2.0 Technologies:
Are they applicable to our libraries?

With the help of Web 2.0 technologies, libraries and information professionals are given a chance to explore and utilize the available web resources to promote, develop and improve the library with the active participation of the clienteles--- giving them power and opportunity to control information, as well as experience access to library services in a more special way.

Some of the most popular Web 2.0 technologies are Instant Messaging (IM), Web blogs, and RSS (Really Simple Syndication), which could potentially provide an adequate development on how library would timelessly presents and deliver its services to its clienteles.

It was a surprise to know that the concept of Web 2.0 is already in existence for quite sometime and that we are already using it, but we are not just aware that these technologies are part of the so called “Web 2.0”. I, myself, I am not familiar with the term, and I didn’t even know that IM , which I have been using for two years now, is part of it.

Instant messaging (IM) is useful for library reference service. Clienteles can easily send-in their requests and queries to the librarian or reference officer without actually going to the library. The librarians can actually respond to clientele concerns through Instant Message. IM provides auto- archive of conversations (you can actually archive the requests/ query transaction per day), show IM status on if busy or available, as well as share or submit document requests to clienteles. Instant messaging also requires familiarity with the available services of the IM, version upgrades, and most importantly, the library staff and clienteles should have create IM IDs, and also a stable internet connection in order to facilitate prompt communication of service.

Blog or Web Blog, can give a more interactive services for clienteles if used in a library set-up. Through this library can make the public know the information about its institution and library as well------ it may include data on library collection and library staff, library service hour, services available, its location and contact information. Blog can be use as an effective publicity media for the current activities of the library since it presents posts on chronological order. Moreover, library could actually include a feedback or comment section for clienteles so that they could dig up some inputs from its users, and whatever are the feed backs-- it could be an ample basis for the improvement or additional services for the library.

The combination of RSS and Weblog create a more advance and interesting services for the library. With this, libraries can provide combine and present different services from a wide variety of resources available on web (such as videos, pictures, and sounds), and make it available from one place to another. Through the use of RSS, library could supply clienteles with information that need to be read or access on a regular basis.

I found IM very useful in my institution because the clienteles of the library donot have to go personally to requests for material, i can easily accomodate their requests through IM. Archived message can also be used for requests documentation, and you can also easily go back to each messages in case you have forgotten it. However, sometimes IM is not also that stable. Based on my experience, sometimes i wasn't able to recieved requests sent through IM and often than not..some IM software downloads are prone to virus (such as Kxvo system files) that are quite hazardeous to the computer system.

With regard to RSS and weblog, i think this could provide and pretty much accomodate interesting services for the library. I just have to be prepared and interested in discovering the web advances of each. I just need the right attitude.. no matter how confusing it is, as long as you have the right attitude towards it, you will definitely learn to appreciate and love it, hence, the course of learning will be easy and fun. And also we should take note that before we publish anything in our blogs, we must always consider the inherent danger or possible outcome of it, especially when its a blog site for our institution -- we should always consider SOPs and confidentialities of related information. ^_^

ABSTRACT

Web 2.0 deals more on the combination of the technology and programming languages on resources and services available on the World Wide Web which allow users to interact or collaborate with each other, thus creating a social network. It paved way for the development and changes of different web- based communities that have undeniable applications to libraries.

As response to this development, libraries would adhere to create a modernized library services that mirrors the progress in libraries on how services are delivered to users with web as its platform, allowing clienteles to interact with the available information, thus creating a likeness called Library and Librarian 2.0 concept which follows some of Web 2.0 essential philosophies, such as: encouraging the application of Online Public Access Catalog (OPAC) systems and increase dynamic participation of users in the design and implementation of services through their feedbacks---- a scenario indistinct to the traditional services of libraries today.

Most of the advances would more or less should be taken into considerations, and learn to be utilize properly by information professionals in order to progress into a Librarian 2.0 equipped with knowledge that could go along with the fast paced development in information, society, and technology.


THINGS THAT I HAVE LEARNED

Web 2.0 can be consider as an abridge representation of the present web based innovations. It allows us to have a control over the information that we create and access it through web. Encouragement for the active participation of the users is the primary idea of its development. Librarian plays important role towards the development and creation of the future Library 2.0 in which the services should be constantly evaluated and updated to meet the changing needs of its users with the aid of the concepts presented by web 2.0.


As information professionals we should make an effort to learn Web 2.0 applications especially now a day that development of information and web services is very fast. Whatever inputs we will get there should not be consider as something that would totally divert or cease our traditional functionality as librarians or information providers. Instead we should take this opportunity as a chance to break away from old service set-up towards the more dynamic and interactive library that would definitely encourage more participation from the end-user of our services.

IMPLICATIONS OF WHAT I HAVE LEARNED

Despite of my unfamiliarity with the various existing concept of Web 2.0 technology I can still say that this had never been a hindrance to me to learn it. There is this eagerness in me to be more participative and be knowledgeable about these advancement concepts.

I believe that knowledge on this is a good foundation towards the improvement of services for my library. Being part of a TV Broadcasting company, it is vital to have a grasp of this, for me to be adequately view its possible applications on the nature of my work.

I believe that we can use this Web 2.0 learning not only to improve our library, but also, to develop ourselves as information specialist and as a being. With these advances, we have a chance to also actively participate with the social networks by freely expressing our point of views on issues, and also share and have a glimpse of the ideas from the other members of the network.

However, as we partake on this development, we should not forget that technology has also its fallback, hence we should prepare ourselves with back ups of everything that we have----- the classic or traditional way of service is still important.

Being skilled with the web applications, it would be easier for us to join whatever advancement would happen in the future. I guess what is really important is that we are prepare and willing to learn.

ABSTRACT:

One of the most important skills for internet searchers today is to how successfully they can search for information on the internet. But since most people are keen to search for specific information on the internet, often than not, most of the useful information available online is not utilized because it could not be found in time of need. However, Boolean operators aided to make these information retrievable, it is use as part of the search strategy for accessing this vast array of information.

Boolean is use to further specify what a search engine to find. Its rule varies from search sites. It plays an important role in the coordination of the search concepts. Results relevancy to the concept being searched varies, basically, results can be too narrow or too broad depending on how concepts are presented. With the use of Boolean operators, search results could focus solely on one concept excluding the other concept (NOT logic), could retrieve all relevant concepts (AND logic), or relevant documents on either of the two concepts (OR logic). Other online search sites uses (+) for AND, and (-) for NOT.

An effective search strategy is feasible through user’s knowledge of concept keywords (its synonyms and word variant forms), and the application of Boolean operator.

THINGS I LEARNED:

Knowledge of the effective search strategy is a must for a researcher. And knowing at least the basics of Boolean operators is a great advantage, and could help minimize the cost of searching.

However, although the Boolean searching is widely used in keyword searches on most computer- based and online – based system, it still has its limitations especially with regard to the retrieved references ---most searches resulted to high recall but low precision. And at the end of the search process, no matter how extent the information retrieved was , the user is still the one who decides which material among the retrieved relevant by the system are said to be relevant based on his own evaluation.

But in some cases that although the clientele is familiar with the Boolean operators, clienteles understanding about the concept that need to be searched, is still the major influencing factor on the search process since the user is the one providing the key concepts. The Boolean operator functions only as connectors that coordinate the concepts provided by the users.

IMPLICATIONS OF THE NEW THINGS I LEARNED:

Through the readings i have learned to appreciate more the importance of having knowledge in Boolean operators for information specialist like me.

The fluency with concepts of data being searched conjunct with Boolean knowledge, is a great advantage for individuals working in a library to immediately assist their clienteles on doing web-based research, and other computer based system search. And also, in a user-based system set-up, providing an accurate constructed query statement (with the aid of Boolean operators) could help limit the time cost needed for just searching for relevant references from various search sites.

Based from what I have often experienced when doing keyword or phrase searches in online- based systems, I often re-do the search because most of the hits does not match what information I need, thus, I use Boolean operators in order to find at least more relevant references that matches my search query. I can say that knowledge on these search operators definitely helped me in adapting with the challenges presented today by the modern information retrieval systems.

ABSTRACT:

Evaluation is absolutely necessary in all research to show progress and to have arguments for the use of certain program or technology.
There are some complexities in pursuing information retrieval system because more people are needed to be involved in the evaluation and ; the evaluation does not just have to focus on the technical proof or technical aspects o the system but also on the effects of the human factors in the process.

In the evaluation process it is essential to verify if the system is build correctly and if it will satisfy its purpose on the organization or institution that will utilize it; and as well as, knowing whether the system satisfies the users or not about the outcome of its search and retrieval functions.

THINGS THAT I HAVE LEARNED:

It is important in any institution to have an effective and efficient information retrieval system-- an IRS that will truly fulfill the objectives of the organization, satisfies the needs of clienteles.

Evaluation of information retrieval system is very important, and this has to be done regularly in order for the organization to have a grasp of the possible or existing problem of the system prior to its application, hence through the tests conducted and evaluation, they could develop plan on how they could minimize the effect of the problem. Or even re-think its performance and cost-effectiveness or efficiency before they implement its application.

Moreover, since information retrieval system performance effectiveness and efficiency is something immeasurable, at the verge of evaluating the system, is important to not only focus on the technicalities related of the system but also on the existing influences of the human factors, specifically the role of the system's end user.

IMPLICATIONS OF WHAT I HAVE LEARNED

I realized that my role as an information service provider is crucial when it comes to providing an effective- efficiency information retrieval system. It is my responsibility to think of a way on how I can make the information on my collection accessible and usable for the users.

Now, considering the fact that not all institutions are prepared for adapting or even implementing an information retrieval system, our skills as information professionals are always put into test. It is our sole responsibility (especially for those one-man librarians – information specialist) to provide a simple retrieval system (for the meantime) to be able to have at least a retrieval system for our institution’s library collection.

Bearing in mind the essence and demand for timeless access to information, we sometimes dared to stick on devising only from what is the available resources we have (although we know that these resources would not suffice the needed support for the system that we are doing), just for us to immediately respond the clientele information needs.

On my part, I opted to devise a simple retrieval system, since my institution immediately necessitates a retrieval system (that will respond to their fast-phased information needs on media materials), in which later I found unsatisfactory because the system application inadequacies became a hindrance to the extensiveness of information that i should have provided for my clienteles.

Hence through this experience, I have seen the importance of a constant evaluation of IR system to be able to know the existing inadequacies, and immediately develop a plan on how to improve the system. Taking also into consideration that, prior to the application of the system, it is better that we have at least a contingency plan so that we will be able to respond immediately to the unexpected fall backs of the system.

We should be able to set what evaluation criteria we will be using for us to know immediately if that particular system fulfills our institution’s objectives, and purposes as retrieval system--- provided that we know the purpose of our system evaluation.

With set criteria, we are certain that we know what areas we need to evaluate, and who will be the people involve in the evaluation of this system----- of course, it should not only be the institution’s management but most importantly, also the end-users of information.

For librarians involve in creating the retrieval system, it is our responsibility to provide appropriate and uniform indexed terms for our collection that will be later used as retrieval points for the user search. Hence, the relevance of the documents retrieve will also depend on how we index the documents/ materials in our collections to make its information retrievable. And on the stage of client searching, we should exercise our roles in providing search assistance, at least provide guidance on familiarizing the clienteles on how the system works to ease their trouble in searching, and also actually observe if the interface or systems application is something that they can easily understood, thus, help minimize the user-cost.

Amidst the existing cost factors, in the end, what ever is the outcome of the IR system evaluation prior to application, it is our responsibility as information professionals to strive for the improvement and the implementation of this IR system in our institutions ( with the hope of gaining support from them, provided that we supplied proper justifications for the importance of this IRS) so we could adequately serve our clientele community.
