A Logic Programming-based Approach to the QA@CLEF05 Track
نویسندگان
چکیده
In this paper the methodology followed to build a question-answering system for the Portuguese language is described. The system has two modules: preliminary analysis of documents (information extraction) and query processing (information retrieval). The proposed approach is based on computational linguistic theories: syntactical analysis (constraint grammars); followed by semantic analysis using the discourse representation theory; and, finally, a semantic/pragmatic interpretation using ontologies and logical inference. The system was evaluated under the CLEF’05 question and answering track with a collection of documents from two newspapers: Público (Portuguese) and Folha de São Paulo (Brazilian).

A Logic Programming Based Approach to QA@CLEF05 Track
In this paper the methodology followed to build a questionanswering system for the Portuguese language is described. The system modules are built using computational linguistic tools such as: a Portuguese parser based on constraint grammars for the syntactic analysis of the documents sentences and the user questions; a semantic interpreter that rewrites sentences syntactic analysis into discour...
متن کاملTREC 2003 Robust, HARD and QA Track Experiments using PIRCS
We participated in the Robust, HARD and part of the QA tracks in TREC2003. For Robust track, a new way of doing ad-hoc retrieval based on web assistance was introduced. For HARD track, we followed the guideline to generate clarification forms for each topic so as to experiment with user feedback and metadata. In QA, we only did the factoid experiment. The approach to QA was similar to what we h...
متن کاملHunting Answers with RAPOSA (FOX)
In this paper, we will present RAPOSA, an early prototype of a question answering system for Portuguese that heavily relies on a named-entity recognition (NER) system to discover answers for several types of factoid and simple definition questions. We will describe the architecture of RAPOSA and explain the role of the NER system in the question answering procedure. We will also compare and dis...
متن کاملTREC-8 Experiments at Maryland: CLIR, QA and Routing
The University of Maryland team participated in four aspects of TREC-8: the ad hoc retrieval task, the main task in the cross-language retrieval (CLIR) track, the question answering track, and the routing task in the filtering track. The CLIR method was based on Pirkola’s method for Dictionary-based Query Translation, using freely available dictionaries. Broad-coverage parsing and rule-based ma...
متن کاملFunction-Based Question Classification for General QA
In contrast with the booming increase of internet data, state-of-art QA (question answering) systems, otherwise, concerned data from specific domains or resources such as search engine snippets, online forums and Wikipedia in a somewhat isolated way. Users may welcome a more general QA system for its capability to answer questions of various sources, integrated from existed specialized sub-QA e...
