Week 7 [03-09.06.2019] Automated identification of media bias in news articles



I want to sharre with you an article with overview of news media bias detection methods. News media bias was well studied in social sciences and now become an interest of computer scientists. There are plenty of text mining, computer vision and other types of algorithms that may be used to detect media bias. I want to ask you the questions below.

  1. 1. What is media bias? What types of media bias do you know?

    Media bias is the bias or perceived bias of journalists and news producers within the mass media in the selection of many events and stories that are reported and how they are covered. The term "media bias" implies a pervasive or widespread bias contravening the standards of journalism, rather than the perspective of an individual journalist or article. The direction and degree of media bias in various countries is widely disputed. There are many types, the most popular one are: Coverage bias, Statement bias, Gatekeeping bias.

    2. Which type of media bias has the greatest impact on the reader?

    I think the bias statement is the most commonly used one. Especially traditional media very much impose their version of events, which is not necessarily true, especially in the case of politics, where unambiguously presented material aims to support one party and completely negatively presents another party. It is very unfair behavior, it is easier to control such information on the internet because it is possible to conduct discussions and two-way communication.

    3. Do you think it is possible to create automatic tools to detect news media bias?

    To some extent, yes, but it will also depend on the autonomy of the creator of such an algorithm, which does not present its own assumptions and preferences only in a completely neutral approach to the matter. You can create a tool that compares publications on the same topic and search for glaring differences, focusing on more publications or the authenticity of the source.

    1. Thank you for your comment.I agree that statement bias has high impact on readers but do you think it applies to alll kind of readers?I think that more frequent readers, the ones that keep an eye on the situatuon all the time, they are aware of this type of bias.

      Yes, creating fair tools is also challenging task

  2. 1. What is media bias? What types of media bias do you know?

    The media's bias is based on the systematic favoring by the mass media of a single position, where these activities serve media corporations, governments or political parties, thereby reinforcing one system of interests and weakening the alternative system.
    The most common forms of bias used to manipulate the media are, for example, election advertising, corporatism, mainstream, media sensation, censorship and bias of the media.

    2. Which type of media bias has the gratest impact on the reader?

    Any type of bias can affect people's attitudes and behavior. Contribute to strengthening or weakening the systems of power, world views, attitudes or political preferences of recipients. I think that kind does not matter. For one it works for another one. It's the same as with coffee. Some people drink black and other white coffee.

    3. Do you think it is possible to create automatic tools to detect news media bias?

    It sounds almost like detection of false messages. Maybe bias simply hides something and does not falsify, while the algorithm would probably be similar.
    I think that at the moment, not soon, though, by using the novelty of artificial intelligence, it certainly does.

    1. True that every types ofbias may influence our behaviour. Different type of people should beawareof different thing.

      Media bias is not about detecting false messages. It also type of bias but the genearal bias is something more. Even the true message may be presented in such way it change our opinion. What about not writing about the truth?

  3. 1. What is media bias? What types of media bias do you know?
    To my mind, media bias is an unethical behavior of persons affecting the presentation of information. I’ve found few types of media bias in presented article, such as: coverage bias, gatekeeping bias or statement bias.

    2. Which type of media bias has the greatest impact on the reader?
    I think that the coverage bias has the greatest impact on the reader. Today, we get the most information from the Internet or social media. Readers tend to follow only the news that conforms with their views. Such kind of media bias is reinforcing their beliefs. This method is very effective.

    3. Do you think it is possible to create automatic tools to detect news media bias?
    I’m not sure. According to the article, there are few approaches in the social sciences to analyse media bias: content analysis, frame analysis or meta-analysis. These three forms of analysis require human interpretation of the texts and cannot be fully automated. Maybe in the future it would be possible to create automatic tools that would be able to read for meaning between the lines.

    1. Thank you for your comment. Yes media bias is unethical and dangerous if exceed some norms. It is hard to avoid because everyone have some view which mau influence the way he write about the world. Is it unethical in this cas as well?

    2. In this case no. Covering the truth or presenting not the whole truth is unethical.

  4. 1. What is media bias? What types of media bias do you know?

    Media coverage often exhibits an internal bias, reflected in news articles and commonly referred to as media bias. Factors influencing this bias can include ownership or source of income of the media outlet, or a specific political or ideological stance of the outlet and its audience.The literature identifies numerous ways in which mediacoverage can manifest bias. For instance, journalists select events, sources, and from these sources the information they want to publish in a news article. This initial selection process introduces bias to the resulting news story. Journalists can also affect the reader’s perception of a topic through word choice, e.g., if the author uses a word with a positive or a negative connotation to refer to an entity, or by varying the credibility ascribed to the source. Finally, the placement and size of an article within a newspaper or on a website determine how much attention the article will receive.

    2. Which type of media bias has the gratest impact on the reader?

    I think the most dangerous thing is to present one group as the best and, at the same time, to discriminate against and present the others as badly as possible.

    3. Do you think it is possible to create automatic tools to detect news media bias?

    There are ongoing studies in this area. However, I do not know if we will be able to obtain a fully independent system one day. In this type of issues even people will be subjective, so I don't know if the computer will be able to learn how to evaluate it objectively.

    1. Thanks for your comment. I cant agree that this kind of bias is the most dangerous. When one group is resented as goood vs another bad it is easy to detect such bias. The most dangerous is when the bias is hidden.It is difficult to obtain fully efficient system even in other fields. It is alway some place for mistakes.

  6. 1. Media bias occurs when journalists and management boards of media stations filter information provided to viewers. The information is chosen not because of their importance, but because of financial or political reasons. Several types of bias are: mainstream, media sensation, overage bias, gatekeeping bias, censorship.

    2. I think that every kind of media bias is bad. The media often have a lot of manipulative power and use it to create the wrong picture of the world in our eyes. The media should be reliable and independent. Currently in Poland we see that every station focuses on supporting a different political faction instead of showing global problems, climate warming, extinction of animals, pollution, etc. Many people do not watch TV, and information comes from the Internet, but there are also many false messages , bending the truth, and above all biased views. In the present world there is little understanding of the position and views of another person, the media only intensifies such conflicts because such topics are sold.

    3. I think that it is impossible right now. There are many methods of bias analysis and many people do it. I think that for the moment, catching nuances in the messages would be too difficult for any algorithm. In addition, there is a problem with obtaining any test files. The biased information can be either a lie, the truth or a modified truth, eg a description of a given situation from a different perspective.

  7. According to the article the madia bias is an intentional and systematic manipulation of presented information to achieve a specific goal. I'm not sure to what "types of media bias" in the question refer to, but I assume those are specific forms of bias described in the article. So when I was thinking about the bias before reading the article it was "labelling and word choice" (naturally I didn't know the term :). I like the deconstruction of bias the authors proposed. I think that from the now on I'll be paying even more attention to it when consuming news.

    I think that facts selection is the most dangerous. Other aspects are often easy to spot while reading/watching news. But when there is some manipulation regarding facts it requires much more effort to even notice.

    It should be possible to create automated tools for detecting bias. It seems that some forms are purely linguistic so one could analyse usage of for example adjectives to detect potential bias. Fact selection could be addressed by some comparison with many other articles about the same subject/event. But all of these seem difficult, especially when we're thinking about a comprehensive solution to the problem.

    The bias of the media is that the media systematically favour a single position in the media, where these activities serve to serve media corporations, governments or political parties, thereby strengthening a single set of interests and weakening the alternative system. Bias is important insofar as it influences people's attitudes and behaviours. A mere statement of bias does not yet prove the influence of the media on the audience, but it may contribute to strengthening or weakening the power systems, world views, attitudes or political preferences of the audience. Distribution and control of political information is one of the attributes and mechanisms of the government.
    In addition, it can be distinguished:
    The following types of bias can be distinguished: unambiguous, propaganda, random and ideological.
    Vvisibility bias when actors or problems are more or less visible in the messages.
    Selection bias when stories are selected or deleted, sometimes for ideological reasons. It is also sometimes referred to as prejudicial to the agenda when it focuses on political actors and whether or not they are taken into account on the basis of their preferred political considerations.
    presentation bias when the media coverage is directed towards or against individual actors or issues.
    Ad2
    Convergent media are the most influential, as they enable more efficient transmission of notifications and making them available to a large number of people, while at the same time targeting target groups with messages that affect their minds and consciousness. The network tools of such influence influence function clearly and coherently, producing a "right" understanding of events and directing the national community towards the goals of the aggressor. Convergent media are both a means of influencing and manipulating information and of implementing scenarios of information aggression.

    Ad3
    On the global scale of the Internet, we are, as users of Polish, a very small community speaking a grammatically complex language. If such a thing exists (because I haven't heard about the solution you have presented), people with the right know-how won't even want to start thinking about it.

  9. 1. What is media bias? What types of media bias do you know?

    Media bias is showing situations in positive or negative way depends on type of information and whom it concerns. I can point election advertising and censure as type of media bias.

    2. Which type of media bias has the gratest impact on the reader?

    In my opinion censure...people don't know about everything so they can't understand some situation well. They known only part of information and based on it make a opinion.

    3. Do you think it is possible to create automatic tools to detect news media bias?

    I think that yes. If any information is in tv news, that could be checking in internet in many sources and show viewer more complex information about this news. That would be helpful.

  10. 1. What is media bias? What types of media bias do you know?

    Media bias is the bias of journalists and news producers in the selection of events and stories that are reported, and how they are covered. One of the definition stands that there are two types of media bias, one of them is Ideological and second I a spin. Ideological bias is present if an outlet biases articles to promote a specific opinion on a topic. Spin bias is present if the outlet attempts to create a memorable story.

    2. Which type of media bias has the gratest impact on the reader?

    Political bias has been a feature of the mass media since its birth following the invention of the printing press. Publishers often served the interests of powerful social groups, for example newspapers, the broadcast media—radio and television—have been used as a mechanism for propaganda from their earliest days, a tendency made more pronounced by the initial ownership of the broadcast spectrum by national governments. Bias occur when the media support or attack a particular political party, candidate, or ideology.

    3. Do you think it is possible to create automatic tools to detect news media bias?

    I think that in times when we have more and more advanced NLP algorithms we going thorward full automation of detecting media bias, but we currently this process is semi - automatic

  11. 1. What is media bias? What types of media bias do you know?
    Media bias refers to the media exhibiting an unjustifiable favoritism as they cover the news.
    The most common forms of bias used to manipulate the media are, for example, election advertising, corporatism, mainstream, media sensation, censorship and bias of the media.

    2. Which type of media bias has the gratest impact on the reader?
    I think the great impact of the reader has bias by story placement. Someone who reads a newspaper know that the most important article is in the top. Media could be positioning such articles to suggest people one thinking direction. Through the play of words journalists could manipulate people and influence theirs decision.

    3. Do you think it is possible to create automatic tools to detect news media bias?
    It is difficult to say. Maybe AI could help to detect media bias. The technology is fast growing and maybe in someday someone will find a method to do it automatically. In this article there are mentioned steps that are required to try to find media bias.

  12. Hi,

    many thanks for interesting issue, not examined by me too deeply before.

    Media bias is the bias of journalists and news producers within the mass media, concerning the selection of events and stories that are reported, and how they are covered. The term “media bias” implies a pervasive or widespread bias contravening the standards of journalism, rather than the perspective of an individual journalist or article.
    There are many types of media bias. most commonly discussed forms of bias occur when the media support or attack a particular political party, candidate, or ideology; however, other common forms of bias exist, including advertising bias, corporate bias, mainstream bias, sensationalism, and concision bias. Advertising bias refers to when stories are selected or slanted to please advertisers; corporate bias refers to when stories are selected or slanted to please corporate owners of media; mainstream bias refers to a tendency to report what everyone else is reporting, and to avoid stories that will offend anyone. Sensationalism is a type of editorial bias in mass media in which events and topics in news stories and pieces are over-hyped to increase viewership or readership numbers. Sensationalism may include reporting about generally insignificant matters and events that don’t influence overall society, as well as biased presentations of newsworthy topics in a sensationalist, trivial, or tabloid manner. Finally, concision bias refers to a tendency to report views that can be summarized succinctly, crowding out more unconventional views that take time to explain.

    In my opinion political media bias has the gratest impact on the reader. It causes a lot of emotions, supporting or being against shall be presented honestly and people don’t want to feel cheated, or manipulated referring to their opinions.

    There are many methods used to analyze the existence of and quantify bias, computer analysis is one of them, in my opinion all methods shall be used to cope with this issue, because it is not possible exactly to solve the problem automatically, as it has many aspects and reasons, which cannot be discovered so easy by programmed tool. Only continuing such fight using all possibilities can help in complementary way, the methods are for example:
    1. Surveys of the political/cultural attitudes of journalists, particularly members of the media elite, and of journalism students.
    2. Studies of journalists' previous professional connections.
    3. Collections of quotations in which prominent journalists reveal their beliefs about politics and/or the proper role of their profession.
    4. Computer word-use and topic analysis searches to determine content and labeling.
    5. Studies of policies recommended in news stories.
    6. Comparisons of the agenda of the news and entertainment media with agendas of political candidates or other activists.
    7. Positive/negative coverage analysis.

  13. Hello Katarzyna, thank you for an interesting subject to discuss.

    1. What is media bias? What types of media bias do you know?
    This is a natural consequence of the subjective human nature that is being revealed in the medium whose role is to be objective. It could be presented in every possible form, including political/advertising/corporate bias.

    2. Which type of media bias has the greatest impact on the reader?
    I think that emotional ones- in every context. The emotion could have an impact on our behaviour.

    3. Do you think it is possible to create automatic tools to detect news media bias?
    Sure, I think that some words could be considered as bias-charged in a given context that could be resolved as unobjective.

  14. 1. What is media bias? What types of media bias do you know?
    Media bias means that certain matters, problems, issues are presented in an unobjective manner, showing only one side of the coin. The most popular media bias, in my opinion, is bias by ommision. One simply doesn't mention certain things that might change the perspective of the reader with regards to the issue shown.

    2. Which type of media bias has the greatest impact on the reader?

    In my opinion, all kinds of media bias, as they all lead to manipulation and disinformation.

    3. Do you think it is possible to create automatic tools to detect news media bias?

    Up to certain extent, yes, but then people will create new methods of manipulations, so the tools will have to be updated and upgraded all the time, but still they will be imperfect and won't detect everything that they should.

    Mainstream bias, a tendency to report what everyone else is reporting, and to avoid stories that will offend anyone.
    Sensationalism, bias in favor of the exceptional over the ordinary, giving the impression that rare events, such as airplane crashes, are more common than common events, such as automobile crashes.
    Structural bias, when an actor or issue receives more or less favorable coverage as a result of newsworthiness and media routines, not as the result of ideological decisions
    False balance, when an issue is presented as even sided, despite disproportionate amounts of evidence.


    3. Do you think it is possible to create automatic tools to detect news media bias?
    In general it seems that such an idea is feasible. But as for most cases devil is in the detail and such actual implementation could be really resource consuming.

  16. 1. What is media bias? What types of media bias do you know?

    The media's bias depends on the mass media favoring one party, group, faction or other institution. Of course, it is described in an ideal matrix, while the opposite faction is described negatively. Known forms of media bias include: election advertising, propaganda, censorship, and media sensation.

    2. Which type of media bias has the gratest impact on the reader?

    In my opinion, it is certainly a media sensation, because all possible copper uses some information in their favor. They put it wherever it is possible so that the widest possible audience can learn about it and assimilate it in a way described by individual media. Interestingly, the media rather do not give the opportunity for ordinary readers to respond to a given topic, but only describe the situation in accordance with their way of understanding.

    3. Do you think it is possible to create automatic tools to detect news media bias?

    I believe that it is possible to create such a tool that allows to capture the bias of the Jews. You can create a list of media, a list of described events, a way of describing the event and compare the same event with other media, so that you have a reference point. The differences that have been captured should be properly defined, or a system defining them should be created. You can also think about doing research among people using different media and ask about how to describe the same event.

  17. 1. What is media bias? What types of media bias do you know?
    It's an un-objective presentation of idea or fact by the media. It can happen in various stages of "production": during selection of facts to present, choice of language, placement on the page or in the time, or combinations.

    2. Which type of media bias has the gratest impact on the reader?
    I think the greatest impact comes from own source selection biases, a.k.a. "echo chambers". Good thing it's usually limited to political topics, but on the other hand, when it happens it tends to reinforce itself to become even stronger.

    3. Do you think it is possible to create automatic tools to detect news media bias?
    Up to some point, I think it is possible. But the we will start to split hairs and invent and observe new kinds of biases I think. Also bias detection gives nothing when we are applying it ourselves by choice of sources to follow.

  18. 1. What is media bias? What types of media bias do you know?
    Like it was mentioned in the publication that You shared with us, there are many different definitions of media bias as well as distinctions of it. Speaking in my own words, media bias is a situation, when information presented by media are not completely neutral, impartial and accordant to reality. It usually happens, when some field of media is running by somebody who wants to present some part of reality in a way he or she sees it.
    And speaking of media bias’ types, I may give You a few examples: events selection (only reports on events that support the preferable authority), source selection (basing Your news only on partial sources, which presents news according to Your point of view), commission and ommission (when You intentionally remove some facts from the news), labeling and word choice, story placement (where in the site with news You place some kind of news), size allocation (how long should be some story), picture selection, picture explanations (captions), and other combined versions of media bias.

    2. Which type of media bias has the gratest impact on the reader?
    In my opinion, from the types of media bias I mentioned in the previous question, the greatest impact on the reader have commissions and ommissions, because when we see the news, in the major part of situations we believe in it. If the news is tottally unbelieveable or impossible even, then we won’t believe in it, but if somebody just ommit one fact from the whole story, it is highly likely that we won’t notice this and therefore we will believe in the news, in spite of the fact that some important part was intentionally removed.

    3. Do you think it is possible to create automatic tools to detect news media bias?
    I think that when You have enough data, than everything can be detected, therefore it is possible to create automatic tools to detect media bias. Although there are many factors which must be taken under consideration in the proccess of distinguish neutral media from biased ones, for example the political or religious views of the media.

  19. 1. What is media bias? What types of media bias do you know?

    The media bias implies a pervasive or widespread bias contravening the standards of journalism, rather than the perspective of an individual journalist or article. Below, I listed the types of media bias which I have ever heard. They are for example: Coverage bias, Gatekeeping bias, Advertising bias, Corporate bias. Coverage bias appears when actors or issues are more or less visible in the news. You can observe the Gatekeeping bias when stories are selected or deselected, sometimes on ideological grounds. Advertising bias appears, when stories are selected or slanted to please advertisers. Corporate bias can be observed when stories are selected or slanted to please corporate owners of media.


    2. Which type of media bias has the gratest impact on the reader?

    I think that each type of media bias has the impact on the reader and I really do not know which has the greatest. I guess that it depends on the situation. Nowadays the coverage bias has the big influence on the reader certainly. Everybody has the access to Internet and social media and some of people like following only the information which are compatible with their point of view. It strengthens their point of view and shows that the media is biased

    3. Do you think it is possible to create automatic tools to detect news media bias?
    I think it is possible to create an automatic tool allowing to detect media bias. The modern neural networks are applied in various fields, so , to my mind, media are not exclusion in that case.
