Dictionary-based Amharic - English Information Retrieval
نویسندگان
چکیده
We present two approaches to the Amharic – English bilingual track in CLEF 2004. Both experiments use a dictionary based approach to translate the Amharic queries into English Bags-of-words, but while one approach removes non-content bearing words from the Amharic queries based on their IDF value, the other uses a list of English stop words to perform the same task. The resulting translated (English) terms are then submitted to a retrieval engine that supports the Boolean and vector-space models. In our experiments, the second approach (based on a list of English stop words) performs slightly better than the one based on IDF values for the Amharic terms.

Amharic-English Information Retrieval with Pseudo Relevance Feedback
We describe cross language retrieval experiments using Amharic queries and English language document collection from our participation in the bilingual ad hoc track at the CLEF 2007. Two monolingual and eight bilingual runs were submitted. The bilingual experiments designed varied in terms of usage of long and short queries, presence of pseudo relevance feedback (PRF), and three approaches (max...

The demand for multilingual information is becoming perceptive as the users of the internet throughout the world are escalating and it creates a problem of retrieving documents in one language by specifying query in another language. This increasing demand can be addressed by designing automatic tools, which accepts the query in one language and retrieves the relevant documents in other languag...

We describe Amharic-English cross lingual information retrieval experiments in the adhoc bilingual tracs of the CLEF 2006. The query analysis is supported by morphological analysis and part of speech tagging while we used different machine readable dictionaries for term lookup in the translation process. Out of dictionary terms were handled using fuzzy matching and Lucene[4] was used for indexi...
متن کاملDictionary-based Amharic-French Information Retrieval
We present four approaches to the Amharic French bilingual track at CLEF 2005. All experiments use a dictionary based approach to translate the Amharic queries into French Bags-of-words, but while one approach uses word sense discrimination on the translated side of the queries, the other one includes all senses of a translated word in the query for searching. We used two search engines: The SI...
متن کاملAn Amharic Stemmer : Reducing Words to their Citation Forms
Stemming is an important analysis step in a number of areas such as natural language processing (NLP), information retrieval (IR), machine translation(MT) and text classification. In this paper we present the development of a stemmer for Amharic that reduces words to their citation forms. Amharic is a Semitic language with rich and complex morphology. The application of such a stemmer is in dic...
