Continuous word representations, trained on large unlabeled corpora are useful for many natural language processing tasks. Popular models to learn such representations  ignore the morphology of words, by assigning a distinct vector to each word. This is a limitation, especially for languages with large vocabularies and many rare words. In this paper, we propose a new approach based on the skipgram model, where each word is represented as a bag of character n-grams. A vector representation is associated to each character n-gram, words being represented as the sum of these representations. Our method is fast, allowing to train models on large corpora quickly and allows to compute word representations for words that did not appear in the training data. We evaluate our word representations on nine different languages, both on word similarity and analogy tasks. By comparing to recently proposed morphological word representations, we show that our vectors achieve state-of-the-art performance on these tasks.

Enriching Word Vectors with Subword Information

How has Japan become a major economic power, a world leader in the automotive and electronics industries? What is the secret of their success? The consensus has been that, though the Japanese are not particularly innovative, they are exceptionally skilful at imitation, at improving products that already exist. But now two leading Japanese business experts, Ikujiro Nonaka and Hiro Takeuchi, turn this conventional wisdom on its head: Japanese firms are successful, they contend, precisely because they are innovative, because they create new knowledge and use it to produce successful products and technologies. Examining case studies drawn from such firms as Honda, Canon, Matsushita, NEC, 3M, GE, and the U.S. Marines, this book reveals how Japanese companies translate tacit to explicit knowledge and use it to produce new processes, products, and services.

A Question of Identity 
Life on the Screen is a fascinating and wide-ranging investigation of the impact of computers and networking on society, peoples' perceptions of themselves, and the individual's relationship to machines. Sherry Turkle, a Professor of the Sociology of Science at MIT and a licensed psychologist, uses Internet MUDs (multi-user domains, or in older gaming parlance multi-user dungeons) as a launching pad for explorations of software design, user interfaces, simulation, artificial intelligence, artificial life, agents, "bots," virtual reality, and "the on-line way of life." 
Turkle's discussion of postmodernism is particularly enlightening. She shows how postmodern concepts in art, architecture, and ethics are related to concrete topics much closer to home, for example AI research (Minsky's "Society of Mind") and even MUDs (exemplified by students with X-window terminals who are doing homework in one window and simultaneously playing out several different roles in the same MUD in other windows). Those of you who have (like me) been turned off by the shallow, pretentious, meaningless paintings and sculptures that litter our museums of modern art may have a different perspective after hearing what Turkle has to say. 
This is a psychoanalytical book, not a technical one. However, software developers and engineers will find it highly accessible because of the depth of the author's technical understanding and credibility. Unlike most other authors in this genre, Turkle does not constantly jar the technically-literate reader with blatant errors or bogus assertions about how things work. Although I personally don't have time or patience for MUDs,view most of AI as snake-oil, and abhor postmodern architecture, I thought the time spent reading this book was an extremely good investment.

Patient-centredness: a conceptual framework and review of the empirical literature.

Online spaces that enable shared public interpersonal communications are of significant social, organizational, and economic importance. In this paper, a theoretical model and associated unobtrusive method are proposed for researching the relationship between online spaces and the behavior they host. The model focuses on the collective impact that individual information-overload coping strategies have on the dynamics of open, interactive public online group discourse. Empirical research was undertaken to assess the validity of both the method and the model, based on the analysis of over 2.65 million postings to 600 Usenet newsgroups over a 6-month period. Our findings support the assertion that individual strategies for coping with "information overload" have an observable impact on large-scale online group discourse. Evidence was found for the hypotheses that: (1) users are more likely to respond to simpler messages in overloaded mass interaction; (2) users are more likely to end active participation as the overloading of mass interaction increases; and (3) users are more likely to generate simpler responses as the overloading of mass interaction grows.The theoretical model outlined offers insight into aspects of computer-mediated communication tool usability, technology design, and provides a road map for future empirical research.

Information Overload and the Message Dynamics of Online Interaction Spaces: A Theoretical Model and Empirical Exploration

If useful explanations are to be provided about the relationship between computer mediated communication (CMC) technologies and online behavior, then a longer-term perspective needs to be taken than the current focus of CMC researchers. This paper provides such a perspective by outlining in theoretical terms how a cyber-archaeology of virtual communities can be conducted. In archaeology, researchers focus on cultural artifacts. A similar focus on the cultural artifacts of virtual communities should be a focus for CMC researchers as these artifacts can provide an integrative framework for a community's life, be it virtual or real. It is proposed that CMC researchers pursue cyber-archaeology by systematically examining and modeling the framework for virtual community life provided by their cultural artifacts.



The systematic exploration of cyber-space via cyber-archaeology cannot proceed without adequate linguistic tools that allow for taxonomy. The first step in the creation of such a taxonomy is to distinguish between virtual communities and their cyber-place, the virtual settlement. The second, is to define and operationalize the term virtual settlement so that they can be systematically characterized and modeled. With this new terminology, it is possible to detail a cyber-archaeology where technological determinism is replaced with the notion of bounded hierarchies and material behavior. The theoretical outline will show how cultural artifacts can play a role in constraining the forms virtual settlements can sustain. The modeling of the boundaries of virtual settlements via cyber-archaeology should dramatically increase our understanding of communication in general.

Patient participation in the cancer consultation: Evaluation of a question prompt sheet

There are few data available on which to base recommendations for effective communication in the cancer consultation. This paper describes a computerised interaction analysis system designed specifically for the cancer consultation and its application in a study investigating the relationship between doctor-patient behaviour and patient outcomes. One hundred and forty-two cancer patients attending their first consultation with a cancer specialist were audio taped and a copy of the tape was retained for interaction analysis. Before the consultation patient anxiety and information and involvement preferences were measured. Outcomes included recall of information, patient satisfaction with the consultation and psychological adjustment to cancer. Doctor behaviour was shown to vary significantly according to the age, sex, involvement preferences and in/out-patient status of the patient. The ratio of doctor to patient talk was related to satisfaction with communication, while patients whose questions were answered showed better psychological adjustment at follow-up. The results suggest that patient-centred consultations lead to improved satisfaction and psychological adjustment. These data provide precise information about consultation behaviour which can be used in the documentation of current practice and the evaluation of new interventions to improve communication.

Computer-based interaction analysis of the cancer consultation.

PURPOSEStudies of tape recordings of cancer consultations have produced conflicting results. At the same time, audiotapes containing general information about cancer are poorly evaluated and are distributed to patients in an ad hoc manner. We compared the effects of both interventions on patient satisfaction, psychologic adjustment, and recall of information following their first consultation with a medical oncologist.PATIENTS AND METHODSPatients (n = 142) were randomized to receive (1) an audiotape of their consultation, (2) an audiotape describing cancer in general terms, or (3) no tape. Recall of information was assessed in a structured interview 4 to 20 days after the consultation.RESULTSSatisfaction with the consultation increased linearly from no tape to general tape to consultation tape. Satisfaction with the tape itself was higher in patients who received the consultation tape (satisfaction score, 61%) compared with those who received the general tape (43%). Average recall for all groups was 6.4 o...
