Reflection on IFN611 Information Retrieval

I completed IFN611 – Information retrieval in my first semester of the Master of Information Science (Library and Information Practice) in 2015.  This was my first semester back at university since completing my first degree in 2000.  Everything had changed in 15 years.  Firstly, I was studying completely externally and online! In my first degree, the personal use of computers, the internet, email and the World Wide Web was only just coming in during the last year or two of my degree, and everyone was on a steep learning curve with this new technology.  Secondly, I was a completely different person studying this time around.  I had already been working as a professional for the last 15 years, developing many professional skills (including very competent computer and Web use skills), and I was motivated, organised, an efficient time manager; and conscious of the need to ensure that I was living a healthy lifestyle.  All of these factors culminated to ensure that my experience of university the second time around was a much better one than the first time.

I really enjoyed studying Information Retrieval.  The subject gave me core knowledge and skills that are essential for any librarian.  I believe that information retrieval comprises an essential component of the librarian’s tool kit.  I enjoyed the content in Information retrieval, and achieved key learnings from the first assignment, which were as follows:

  • Prior to conducting any search for information, define and specify the client’s information need carefully in a client interview, so that appropriate and relevant search objectives emerge.
  • I must have a breadth of knowledge of relevant search tools, including databases and search engines, in order to select an appropriate tool in which to search.
  • When constructing search strategies, a thorough knowledge of the unique search features of each online search tool is required to obtain the most relevant results from the search.
  • Evaluate results carefully to ensure that they are of adequate quality in terms of reliability, credibility, authority, validity, accuracy, timeliness and point of view.

Apart from the standard learnings about the standard information search and retrieval process (listed above), I also enjoyed learning about other models of the information seeking process in Hearst (2009); including Bates’ (1989) Dynamic (Berry-Picking) model.  This model evolved from observational studies of the information seeking process, in which it was found that the searcher’s information needs continually changed as they read and learned from the information encountered during the search process.  They might find new keyword suggestions, and formulate new questions along the way.  The main value of the search was in the learning and acquisition of information that occurred during the search process, rather than in the final set of results.  This model is the one that most closely aligns with the way I conduct a search for information for my own assignments.  To me, it is an exciting adventure to embark on a search for information.  My information need and search query is always vague and only partially outlined, because I rely on learning more about the subject as I go, finding new keywords, and exciting new paths to follow.  The blanks get filled in as I go.

Of course, I see that in a workplace environment, an efficient, systematic method is called for to retrieve information for users; therefore, the standard method is very useful for librarians when they are assisting users to find the information they need.  The standard method presents a systematic way to efficiently extract the information need from the user, construct a search strategy, search for, and retrieve quality information for the user.  I will leave the berry-picking model for my own information search process.  Although, it might be good to remember it for any classes in information retrieval I might teach in the future.

Accuracy, misinformation and pseudoscience on the internet

Climate change doesn’t exist.

Immunisation causes autism.

Fluoride is poison.

Scientists and governments don’t want you to know.

These are some of the things you might read on the internet.  They may be quite persuasive, depending on your particular set of values, beliefs and knowledge. But are they true? How do you know? How do you find out? Today’s blog post will discuss some of these issues.

What is accuracy on the internet?

Accuracy on the internet refers to the truth of the information: true or false, right or wrong, black or white.  We know that there is no guarantee that the information we find on the internet is accurate. Anyone can publish anything they like.  There may be no review process or fact-checking of the information prior to it being published, as there is for other published information, such as newspapers, journals, books and magazines.

Evaluating the quality of information on the internet

The notion of “accuracy” is limited because it refers to information that can be held up to some objective notion of “truth”.  This may work for some kinds of information, e.g. science (more on science later), geography and mathematics; but there is a lot of information on the internet that is not fact-based, but based on someone’s opinion.

We are talking about a bigger concept than simply whether the information we are reading is accurate or correct. We are referring to the quality of the information, which has many dimensions, of which accuracy is one.  QUT’s Study Smart Research and Study Skills Tutorial uses the following 6 criteria in evaluating internet resources:

  1. Reliability of the source: the credentials of the author and the publication are used to establish authority and credibility of the information.
  2. Validity: documentation of research methods, and inclusion of references.
  3. Accuracy: facts are cited and referenced; spelling and grammar is accurate.
  4. Authority of the author: Information is provided about the author, as well as their affiliations to organisations, their qualifications and experience.
  5. Timeliness: refers to information about when the information was created or published, and whether the information is updated. Currency of information is important in areas of rapid change, such as information technology.
  6. Point of view: Information is evaluated to decide if it is biased or unbalanced.

People need to evaluate internet resources based on a number of criteria to determine whether it is good quality information. The skills involved in evaluating information are part of a larger skill set referred to as “Information literacy”.

What is information literacy?

The Association of College and Research Libraries (ACRL), a division of the American Library Association (ALA) defines information literacy as the abilities that enable individuals to “recognise when information is needed and have the ability to locate, evaluate, and use effectively the required information.”

Determining the accuracy of information on the internet comes into the “evaluate” part of the definition.  People need to have the skills to critically evaluate information. This is really important! Many adults don’t have the skills to do it, taking for granted that the information they read on the internet is correct.

What is misinformation?

Misinformation refers to inaccurate or false information that is spread intentionally or unintentionally.

Misinformation on the internet is a bit scary.  Read some of the stories on What’s the Harm?   and listen to this episode of Ockham’s razor on ABC Radio National if you don’t believe me.

In this episode, Tory Shepherd, Senior Writer for the Advertiser in Adelaide, worries about today’s kids, wondering how they will ever be able to determine truth, logic and reason, when truth is your own opinion, experts are hiding the truth, and science is no longer an objective, observable source of truth, but a belief system, which you can choose to believe in, or not.  She discusses how powerful the pseudoscience on a number of issues has become, and how resistant to extinction; particularly the pseudoscience on climate change, the anti-vaccination movement and fluoridation.  Her concern is that these movements can have such strength that they actually influence public policy.  She mentions a couple of politicians who believe that fluoride is a neurotoxin that politicians want to put in the water to poison the population.  She discusses the danger of people doing their own research, distrusting experts, and not knowing the limits of their own knowledge.

Why is misinformation so effective?

I found out that there are a few interesting psychological explanations for the power of misinformation; including:

  • It takes cognitive effort to evaluate the plausibility and source of a message. If you don’t really care about the topic, or you don’t have time to think about it or evaluate it, you may be more likely to accept the misinformation as fact.
  • When people do evaluate the message, they mainly consider whether the information agrees with what they already believe (confirmation bias).

When efforts are made to retract misinformation, often times they don’t work, and may even increase the person’s belief in the misinformation.

Cousins’ article states that there are real dangers of misinformation; particularly in terms of misinformation of the majority possibly influencing political decisions; and misinformation of individuals potentially causing them to make poor decisions with serious consequences.

Cousins believes that misinformation is worse than ignorance.

Is there a solution?

Education in critical thinking and information literacy skills are very important.  But I wonder if that is a complete solution.  Education won’t help everyone. Education may not unseat the misinformed beliefs that some people already hold, due to their distrust of science and expert opinion, or confirmation bias.  And what about vulnerable people who have limited cognitive, learning, intellectual or other impairments; with concomitant poor literacy, poor reasoning skills, and inability to conduct a critical evaluation of internet information?  Children are another vulnerable group, who potentially risk being harmed by carers with misinformed, pseudoscientific beliefs.

I don’t have the answer.  But I can envisage an ideal world where there might be a benevolent, independent global community of editor/s (maybe librarians? Maybe Wikipedia editors?) who would asterisk potentially suspect internet sources and indicate why they may not be the most credible, reliable or accurate source of information.
