Automatic Retrieval of Good Dictionary Examples

Automatic Retrieval of Good Dictionary Examples

Abstract: This thesis proposes and implements an algorithm for evaluation of sentences with respect to their understandability and informativeness. It can be embedded into a variety of applications, such as corpus querying tools or automated dictionaries. The proposed algorithm is highly customizable, since it employs a variety of criteria approximating the similarity of sentences to good dictionary examples. It was optimized using machine learning algorithms according to a set of manually labelled concordances. The algorithm is usable in practical applications, however it is still being developed. …víceméně

Zadání: Both the electronic and printed dictionaries contain examples as a part of dictionary entries. The examples illustrate a usage of a word (or phrase) and are very popular with foreign language learners. Therefore, the quality of these examples inevitably affects the quality of the whole dictionary. In modern dictionaries these examples are usually chosen from text corpora, which represent the real (not artificially created) usage of particular expressions. The aim of this thesis is to design and implement an algorithm, which automates (or at least simplifies) the retrieval of suitable examples illustrating a given word or phrase. The output of this thesis should be a system helpful to lexicographers for creating new dictionaries based on text corpora. It is advisable to incorporate it into an existing corpus query system. …víceméně
