Craveiro, Olga; Macedo, Joaquim; Madeira, HenriqueIn this work, we introduce a software testbed for temporal processing of Portuguese texts, composed by several building blocks: identification, classification and resolution of temporal expressions and temporal text segmentation. Starting from a simple document, we can reach a set of temporally annotated segments, which enables the establishment of relationships between words and time. This tem- porally enriche...
Towards a segment-based temporal information retrieval model
Craveiro, Olga; Macedo, Joaquim; Madeira, HenriqueThe extraction of temporal information from text documents is becoming increasingly important in many applications such as natural language processing, information retrieval, question answering, etc.. Indeed, the temporal dimension plays a key role on most of these systems, promoting better performance. Our goal is the definition of a temporal document representation, incorporating the time dimension into infor...
Use of Co-occurrences for temporal expressions annotation
Craveiro, Olga; Macedo, Joaquim; Madeira, HenriqueThe annotation or extraction of temporal information from text documents is becoming increasingly important in many natural language processing applications such as text summarization, information retrieval, question answering, etc.. This paper presents an original method for easy recognition of temporal expressions in text documents. The method creates semantically classified temporal patterns, using word co-o...
