Czech Subjectivity Lexicon: A Lexical Resource for Czech Polarity Classification
نویسنده
چکیده
This paper introduces Czech subjectivity lexicon – the new lexical resource for sentiment analysis in Czech. The lexicon is a dictionary of 4947 evaluative items annotated with part of speech and tagged with positive or negative polarity. We describe the method for building the basic vocabulary and the criteria for its manual refinement. Also, we suggest possible enrichment of the fundamental lexicon. We evaluate the current version of the dictionary by implementing it to the classifiers for automatic polarity detection and compare the results of both plain and supplemented system.

متن کاملSemantic Classes in Czech Valency Lexicon: Verbs of Communication and Verbs of Exchange
We introduce a project aimed at enhancing a valency lexicon of Czech verbs with coherent semantic classes. For this purpose, we make use of FrameNet, a semantically oriented lexical resource. At the present stage, semantic frames from FrameNet have been mapped to two groups of verbs with divergent semantic and morphosyntactic properties, verbs of communication and verbs of exchange. The feasibi...
متن کاملWhy Words Alone Are Not Enough: Error Analysis of Lexicon-based Polarity Classifier for Czech
Lexicon-based classifier is in the long term one of the main and most effective methods of polarity classification used in sentiment analysis, i.e. computational study of opinions, sentiments and emotions expressed in text (see Liu, 2010). Although it achieves relatively good results also for Czech, the classifier still shows some error rate. This paper provides a detailed analysis of such erro...
متن کاملValency Lexicon of Czech Verbs: Towards Formal Description of Valency and Its Modeling in an Electronic Language Resource
Valency refers to the capacity of verb (or a word belonging to another part of speech) to take a specific number and type of syntactically dependent language units. Valency information is thus related to particular lexemes and as such it is necessary to describe valency characteristics for separate lexemes in the form of lexicon entries. A valency lexicon is indispensable for any complex Natura...
