Query Processing in a Video Retrieval System
نویسندگان
چکیده
In an earlier paper, we designed a similarity based video retrieval system. Queries are speciied in a language called Hierarchical Temporal Language (HTL). In this paper, we present several extensions of the HTL language. These extensions include queries that can have the negation operator and any other logical and temporal operators such as disjunction. EEcient algorithms for processing queries in the extended language are also presented.

Boosting Passage Retrieval through Reuse in Question Answering
Question Answering (QA) is an emerging important field in Information Retrieval. In a QA system the archive of previous questions asked from the system makes a collection full of useful factual nuggets. This paper makes an initial attempt to investigate the reuse of facts contained in the archive of previous questions to help and gain performance in answering future related factoid questions. I...
متن کاملSemiautomatic Image Retrieval Using the High Level Semantic Labels
Content-based image retrieval and text-based image retrieval are two fundamental approaches in the field of image retrieval. The challenges related to each of these approaches, guide the researchers to use combining approaches and semi-automatic retrieval using the user interaction in the retrieval cycle. Hence, in this paper, an image retrieval system is introduced that provided two kind of qu...
