Papageno: Predictive Models for Crisis Intelligence
Last Updated: Stockholm, 15 May 2013 Papageno: A Pilot Study to identify suitable Predictive Models for Crisis Intelligence I need some help to jot down real-world use cases for crisis intelligence. Could you please point out to me past events or previous experiences that can be useful for a pilot study? ”Crisis intelligence” is a new research area that is becoming more and more crucial in medium-large organizations and companies. It consists in detecting an upcoming “crisis” (a scandal or general dissatisfaction or any negative attitude) by automatically analysing text documents of any kind in electronic format. Many commercial and open source solutions are proposed to identify the “mood” and the sentiment of masses with respect to a certain event, brand, or person through tweets, blogs, etc. But very little research has been carried … Read entire article »

Towards a Cross-Lingual Lexical Knowledge Base of Lexical Forms
Last updated: 15 May 2013 How do you overcome problems related to cross-linguality? My specific problem at them moment is caused by the poor coverage of everyday language in lexical resources. For instance, the Swedish single-word expression /egenremiss/ (14,900 hits, Google.se April 2013) – or alternatively as a a multiword expession (MWE) – /egen remiss/ (8,210 hits, Google.se April 2013) denotes a referral to a specialist doctor written by patients themselves. This expression is made up from two common Swedish words /egen/ `own (adj)’ and /remiss/ `referral’. It is a recent expression (probably coined around 2010*) and not yet recorded in any official dictionary nor in Wiktionary or other multilingual online lexical resources. This compound happens … Read entire article »

Book in Preparation: A Computational Theory of Digital Genre
Book in preparation: A Computational Theory of Digital Genre by Marina Santini The book lists, examines and develops the key concepts necessary to build a novel, intuitive and robust definition of digital genre for computational purposes. The newly proposed definition is the tenet of the computational theory underlying computational models for automatic digital genre classification. The book is divided into six parts, each one discussing exhaustively issues that have been neglected or considered to be too controvertial to find any theoretical or pragmatic agreement among scholars or researchers. The book provides not only theoretical foundations, but also a number of use cases, corpora/datasets, and computational models that readers can re-use for their own experiments to evaluate … Read entire article »

Dear all, I wonder if you have any experience or if you can provide references on how to build automatically a glossary from genre-specific corpora.

Reflection: Analysing Emotions of Social Writing
by Marina Santini A few days ago, I attended a fascinating session organized by the Quantified Self Stockholm (QS) MeetuUp, in a venue with an inspiring name, Psykologifabriken (The Psychology Factory), in center Stockholm. This QS session – Adding Power to body and soul… – included two presentations: one about adding power to the body through a robotic glove that adds gripping energy to the hand of those who have lost strength in this limb; the other one about methods to enable self-development through digital tools. Since I am not into robotics, I will only say that the empowering glove shown by Johan Ingvast from Bioservo is simply amazing… I am not a psychologist either, but I found the presentation … Read entire article »
Question: How to Define Criteria for Subgenre Classification?
I had an interesting email exchange with Christophe Clugston, a researcher currently located in Thailand, about the classification of a specific subgenre belonging to the Netadvertising supergenre. He says: “I am looking at classifying a very narrow sub genre. Within the domain of Netvertising I am looking at an extant, variant genre that I am terming Long Scroll Web Advertisements (as the off line version is termed Long Copy Advertising). This type of advertising is very different than the multi media image tied to a few words or few clauses. It is based entirely on the factor of extended reading (some of these ads are over 24 pages when printed). I have enclosed a link to … Read entire article »
