    2. 2. ObjectiveAnalyze the behavior of emergency governmentalagencies on social networks in crisis situationsSome questions that arise:- Are social networks used in crises? If so, - When are they used? (e.g. Pre-crisis, during crisis or post-crisis) - What kind of information is published?- Is there a communication with other users? If so, - With who? General public and/or other agencies? - Is it a one-way or two-way communication?- Other…References: DEI Meeting – 10/nov/2011
    3. 3. Possible data• Quantitative: – # of publications – # of retweets, reply/mentions, shares, likes, etc.• Qualitative: – Type of content published – Meta-data of posts (date and time, location, etc.) – Multimedia elements – Communication and interaction with other accountsReferences: DEI Meeting – 10/nov/2011
    4. 4. Methodology• Grounded theory: An inductive qualitative research method which starts from a set of data and aims to develop a theory. It consists on an iterative process of data collection and analysis in order to extract a theory [Glasser & Strauss, 1967; Corbin & Strauss, 2008]. – Stages: • Open coding • Development of concepts • Grouping concepts into categories • Formation of a theory• Content analysis: “Any technique for making inferences by objectively and sistematically identifying specified characteristics of messages.” [Holsti, 1969]References: DEI Meeting – 10/nov/2011
    5. 5. Methodology• Coding Coding is a process to analyze text content that “involves interacting with data, making comparisons between data, and so on, and in doing so, deriving concepts to stand for those data, then developing those concepts in terms of their properties and dimensions” *Corbin et al., 2008].• Common procedure: – Based on a set of collected data, coding can be a priori or emergent. It usually requires different analysts to code the data (or a subset), compare and consolidate the categories, reliability test on coded data and repetitions of the procedure in order to achieve a reliable analysis.• Similar approaches: – Action-object pairing with coding techniques [Zhang & Jansen, 2008] – Noticing, collecting and thinking [Seidel, 1998]References: DEI Meeting – 10/nov/2011

    8. 8. Ideas & proposal• A multi-step approach consisting on: – Selecting a set of governmental agencies involved in crisis management from different countries and with diverse competences (with accounts on social networking sites) • EMA, OEP, police, national guard, etc. – Data collection using social networks APIs from past events – Iterative open-coding process to define initial categories • Various coders? • A priori coding based on literature (on/off-topic, crises stages, …) – Validation and consolidation of categories • If applies, definition of subcategories and relation of concepts – Perform reliability tests – Repeat the process, use a present or close event to validate coding.References: DEI Meeting – 10/nov/2011
    9. 9. Possible events to study• The crisis events to analyze may have the following characteristics: – Recent events from the past two years or less – Events from different locations and reach/scope – Events with different types based on the EM-DAT classification ( DEI Meeting – 10/nov/2011
    10. 10. Practical issues• Technological – Public availability of social network publications depends on the site preferences and each account’s settings – Time of publications and availability: for instance, Twitter search API only allows retrieving recent data with a maximum of 3200 tweets• Resources – The coding technique requires multiple coders to code content iteratively, comparison of categories and reliability assessmentReferences: DEI Meeting – 10/nov/2011
