Abstract

Current Web-search engines can be improved through techniques that consider a temporal dimension in both query formulation and information extraction processes. An accurate recognition of temporal expressions in data sources is required, as well as extracting semantic embedded meta-information concerning time in a standard format that allows reasoning without ambiguity. Temporal Web searching entails an interesting advance on the way to the Semantic Web. We propose a temporal expressions recognition and normalization (TERN) system for contents in Spanish, which has been integrated into a Web-search engine prototype. The contribution of this system lies in its capability of taking into account the semantics of time in the user queries as well as in the search collections, independently of its representation. Evaluation figures show that the inclusion of temporal information management aptitudes to Web searching means considerable improvements in its performance.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
