Putting News in a Perspective: Framing by Word Choice and Labeling

Descargar para leer sin conexión

While following the news, one can notice the same story can
have different impact depending on which news agent tells
it. One reason for this is how the facts are framed. Framing is described by communication sciences as an instrument
influencing on how people perceive, interpret and convey information. It can be obtained by use of specific word choice
and labeling that describe event or problem from a particular perspective, e.g. positive or negative. In order to derive a frame, social sciences usually perform a manual qualitative analysis, but recently a computer-assist quantitative
approaches commence to be an essential way of conducting
framing analysis. This work provides a literature review on
the existing frame derivation methods based on problem of
word choice and labeling.

  2. 2. Agenda 1. Introduction: What is a frame? 2. Framing analysis 3. Research questions 4. Inductive approaches 5. Deductive approaches 6. Discussion of results 7. Future work 8. Conclusion 07/02/2017 Putting News in a Perspective: Framing by Word Choice and Labeling 2
  3. 3. What is a frame? 07/02/2017 Putting News in a Perspective: Framing by Word Choice and Labeling 3 Framing is a conceptualization of an issue, the way how people organize, perceive, and communicate information. Example: After this procedure 90% of patients are alive After this procedure 10% of patients are deceased The information in the two sentences is the same.
  4. 4. What is a frame? 07/02/2017 4 ➢ A frame is central organizing idea, that selects and emphasizes information. ➢ Framing devices are salient indicators of a frame • Word choice • Metaphors • Catchphrases • Visual images • Stereotypes • Labels • Etc. ➢ Framing is a type of media bias. ➢ It influences on how people interpret and use information. Putting News in a Perspective: Framing by Word Choice and Labeling Frame
  5. 5. Word choice and labeling 07/02/2017 Putting News in a Perspective: Framing by Word Choice and Labeling 5 Word choice: • Influences on the message, changing its perception Example: “Heart-wrenching tales of hardship faced by people whose care is dependent on Medicaid” VS “Information on the lifestyles of Medicaid dependents” Labeling: • Describes someone or something in one word • Refers to stereotypes Example: political party (democrat/republican), religion (Muslim/Christian), race (black/white), etc.

  10. 10. Inductive approaches 07/02/2017 Putting News in a Perspective: Framing by Word Choice and Labeling 10 How to find frames? Most frequent words Correlation between words [1] • Cosine similarity matrix • PCA • Hierarchical clustering Word co-occurrence [4] • Semantic network • Cosine similarity matrix • Value ≥ threshold  node in a network [3] • Word = neuron • Self-organizing map • Hierarchical clustering [2] • Covariance matrix • PCA • Significant eigenvalues frames
  11. 11. Inductive approaches 07/02/2017 Putting News in a Perspective: Framing by Word Choice and Labeling 11 Most frequent words … Text structure Center resonance analysis [5] • Noun phrases = idea centers • Word co-occurrence  resonance of words • PCA Keyword-weight model [6] • Weight words according to location of occurrence • Location = place in news pyramid •Aspect-based clustering How to find frames?
  12. 12. Inductive approaches 07/02/2017 Putting News in a Perspective: Framing by Word Choice and Labeling 12 Most frequent words … Text structure … Semantic meaning [7] • Latent semantic analysis • High cosine similarity  words with similar meaning Keywords [8] • Log-likelihood ratio of words in a list w.r.t. reference word-list • Word co-occurrence • Qualitative analysis Named entity recognition [9] • Extract different entity categories • Find salient terms • Qualitative analysis How to find frames?
  13. 13. Deductive approaches 07/02/2017 Putting News in a Perspective: Framing by Word Choice and Labeling 13 Classification How to find presence of frames? Logistic regression Ensemble of logistic regressions Supervised Hierarchical LDA [10] • Binary classifier • 1 classifier = 1 frame • Features: based on word’s presence/absence in a vocabulary • Prediction = measure of frame presence [11] • Collection of classifiers • 1 classifier = 1 framing device • Features: based on TF-IDF score • Prediction = measure of frame device presence [12] • Probabilistic model • Forms frames around assigned label
  14. 14. Deductive approaches 07/02/2017 Putting News in a Perspective: Framing by Word Choice and Labeling 14 How to find presence of frames? Classification … Homogeneity analysis Clustering Rule-based approach [13] • Clusters = frames • Features = based on coding agreement of framing device • Hierarchical clustering [14] • Homogeneity analysis most influential devices in each frame • Final result for a text: 2 indices of 2 frames’ presence [15] • Semantic Network analysis • Framing devices = sentences • Texts = network of sentences • Sentence is parsed into 3 roles
  15. 15. Discussion RQ1: How do scholars approach computer-assisted framing analysis? 07/02/2017 Putting News in a Perspective: Framing by Word Choice and Labeling 15 Inductive Deductive Word Frequency • Correlation • Co-occurrence Classification Text Structure • Central Resonance Analysis • Keyword-weight model Homogeneity analysis Latent Semantic Analysis Clustering Keywords Rule-based approach Named Entity Recognition
  16. 16. Discussion RQ2: What are the methods that focus analysis on constructing frames based on word choice and labeling? 1. Keyword-weight model  word choice is connected with the most prominent parts on news 2. LSA  semantic similarity of words could addressed word choice influence 3. LSA  semantic similarity of labels w.r.t. the context 4. Named Entity Extraction  salience topics, framing devices, and if extended, labels 5. Neural Network  concentration around salience concepts. Log-likelihood instead of frequent words in an option. 6. Current methods don’t capture “between line” information 7. Frames representing same entity from several perspectives are not united to one concept. 07/02/2017 Putting News in a Perspective: Framing by Word Choice and Labeling 16
  17. 17. Future work 1. LDA as topic modeling could be used for inductive analysis 2. Review other keyword or keyphrase extraction methods 3. Use named entity extraction for framing devices identification 07/02/2017 Putting News in a Perspective: Framing by Word Choice and Labeling 17
  18. 18. Conclusion Performed a comprehensive literature review. Current approaches: + Focus on interpretation of frame definition from social sciences + Address both inductive and deductive analysis + Frames are based on semantic and structural properties of text - Mostly semi-automated analyses - Represent more agenda-setting analysis rather than framing - Construction of framing devices is not solved 07/02/2017 Putting News in a Perspective: Framing by Word Choice and Labeling 18
