Using Part of Speech Tagging in Persian Information Retrieval
نویسندگان
چکیده
With the emergence of vast resources of information, it is necessary to develop methods that retrieve most relevant information according to the users needs. These retrieval methods may benefit from natural language constructs to boost their results by achieving higher precision/recall rates. In this attempt, we have used part of speech attributes of terms as extra information about document and query terms and have evaluated the impact of such information on the performance of the retrieval algorithms. Also the effect of stemming has been experimented as a complement to this research. Our findings indicate that part of speech tags may have small influence on effectiveness of the retrieved results. However, when this information is combined with stemming it improves the accuracy of the outcomes considerably.

Applying Natural Language Processing Techniques for Effective Persian- English Cross-Language Information Retrieval
Much attention has recently been paid to natural language processing in information storage and retrieval. This paper describes how the application of natural language processing (NLP) techniques can enhance cross-language information retrieval (CLIR). Using a semi-experimental technique, we took Farsi queries to retrieve relevant documents in English. For translating Persian queries, we used a...
متن کاملAn improved joint model: POS tagging and dependency parsing
Dependency parsing is a way of syntactic parsing and a natural language that automatically analyzes the dependency structure of sentences, and the input for each sentence creates a dependency graph. Part-Of-Speech (POS) tagging is a prerequisite for dependency parsing. Generally, dependency parsers do the POS tagging task along with dependency parsing in a pipeline mode. Unfortunately, in pipel...

Abstract: Part-Of-Speech (POS) tagging is essential work for many models and methods in other areas in natural language processing such as machine translation, spell checker, text-to-speech, automatic speech recognition, etc. So far, high accurate POS taggers have been created in many languages. In this paper, we focus on POS tagging in the Persian language. Because of problems in Persian POS t...
متن کاملA hidden Markov model for Persian part-of-speech tagging
One of the important actions in the processing of languages is part-of-speech tagging. Against of this importance, although numerous models have been presented in different languages but there is few works have been done in Persian language. In this paper, a part-of-speech tagging system on Persian corpus by using hidden Markov model is proposed. Achieving to this goal, the main aspects of Pers...
