A Sentimental Education: Sentiment Analysis Using Subjectivity Summarization Based on Minimum Cuts
Sentiment analysis seeks to identify the viewpoint(s) underlying a text span;
an example application is classifying a movie review as "thumbs up" or "thumbs
down". To determine this sentiment polarity, we propose a novel
machine-learning method that applies text-categorization techniques to just the
subjective portions of the document. Extracting these portions can be
implemented using efficient techniques for finding minimum cuts in graphs; this
greatly facilitates incorporation of cross-sentence contextual constraints.Comment: Data available at

Preliminary study of head-up assessment techniques. 1: Viewing duration of instrument panel and HUD symbology using a recall methodology
Eight commercial pilots were shown 50 colored, high fidelity slides of a standard instrument panel (IP) with the needle positions of each instrument varying from slide to slide and then 50 slides of a head-up display (HUD) symbology format which contained an equivalent amount of flight-related information as the instrument panel slides. All stimuli were presented under controlled, static viewing conditions that allowed the measurement of the speed and accuracy with which one randomly selected flight parameter on each slide could be read. The subject did not know which parameter would be requested and, therefore, had to remember the total set of information in order to answer the question correctly. The results showed that from 6.6 - 8.7 sec total viewing time was required to correctly extract altitude, airspeed, heading, VSI, or ADI from the IP slides and from 6.1 to 7.4 sec for the HUD slides
Attitudes, Ideological Associations and the LeftâRight Divide in Latin America
Do Latin American citizens share a common conception of the ideological leftâright distinction? And if so, is this conception linked to individualsâ ideological self-placement? Selecting questions from the 2006
LatinobarĂłmetro survey based on a core definition of the leftâright divide rooted in political theory and philosophy, this paper addresses these questions.
We apply joint correspondence analysis to explore whether citizens who relate to the same ideological identification also share similar and coherent convictions and beliefs that reflect the ideological content of the leftâright distinction. Our analysis indicates that theoretical conceptions about
the roots of, and responsibility for, inequality in society, together with the
translation of these beliefs into attitudes regarding the state versus market divide, distinguish those who self-identify with the left and those who selfidentify with the right
Working out a common task: design and evaluation of user-intelligent system collaboration
This paper describes the design and user evaluation of an intelligent user interface intended to mediate between users and an Adaptive Information Extraction (AIE) system. The design goal was to support a synergistic and cooperative
work. Laboratory tests showed the approach was efficient and effective; focus groups were run to assess its ease of use. Logs, user satisfaction questionnaires, and interviews were exploited to investigate the interaction experience.
We found that userâ attitude is mainly hierarchical with the user wishing to control and check the systemâs initiatives. However when confidence in the system capabilities rises, a more cooperative interaction is adopted
An Empirical Analysis of Internal Marketing on Organizational Commitment:a Study of Banks in Lagos-Nigeria
The purpose of this paper was to investigate the effects of aspects of internal marketing on organizational commitment of employees. The research was conducted among managers of Nigerian banks situated in the major commercial city in Lagos, Nigeria. Internal marketing is growing recognition of both scholars and professionals with the increasing commoditization of products and services and the continuing failure of technology driven customer relationship management. The main criteria of internal marketing were derived from the literature; provided the backbone for our internal marketing dimensions. Data was gathered from a survey among 128 managers who rated self completion questions on the basis of their perception. In order to achieve the purpose, five hypotheses have been formulated that link the dimensions of internal marketing including motivation, job satisfaction, training,â understanding and differentiationâ, âinter-functional coordination and integrationâ âto organizational commitment. Data analysis indicated that âinter-functional coordination and integrationâ, training and motivation have positive effects on the organizational commitment of employees among Nigerian banks. Therefore if the banks want to ultimately provide a better service experience for their customers, it is recommended that more attention be directed toward enhancing organizational commitment among personnel, with a focus on the effective aspects of internal marketing
